{Self-latching arrangements}
Definition statement

This place covers:

Leaf springs that can be latched in a position (usually open or biased position). This latching should not be due to the spring activating arrangement but to the spring itself.

The following figures show a leaf spring (14). On figure 1, the leaf spring is latched in the biased open position. The greyed-out portions (25a) and (25b) of the spring are resting on the greyed-out surface (27a) and (27b) of the spring itself. On figure 3 the latching configuration is removed and the spring is biasing the core (12) of the wire (11).

media372.png

The following figure shows a leaf spring (200) which is coiled on itself and latched in a biased position by the part of the spring itself highlighted in grey and pointed out by the arrow. Insertion of a wire (1a) will push down the bottom left end of the spring thereby releasing the cantilevered lance.

media373.png

Relationships with other classification places

Leaf springs latched by the spring activating arrangement are covered by group H01R 4/4835.

{the spring shape preventing insertion of the conductor end when the spring is unbiased}
Definition statement

This place covers:

Spring clamped connections requesting an opening of the spring before being able to insert the wire. In its un-biased position, the spring prevents the conductor to be inserted in the connection area of the spring e.g. by presenting a flat portion blocking the insertion channel of the conductor or by guiding the wire away from the spring.

The following figures show a busbar (31), a leaf spring (32) and a wire (60) that cannot be connected to the spring without previously opening it. The wire connecting site is greyed-out on figure 5b below between the vertical part of the busbar and the moving horizontal edge of the spring. On figure 4b the leaf spring is abutting on the busbar and the end of the leaf spring obstructs the connecting site suitable for receiving the wire. On figure 5b, as the spring is biased by the element (40), then the connection site for the wire (60) is opened between the busbar and the spring.

media374.png

The following figures show a leaf spring (102). On figure 3, the leaf spring is in the unbiased position and the connection site between (214) and (230) is not available because the two ends of the spring are not aligned and are not forming the insertion site for the wire. On the contrary, after biasing the spring (pushing the movable greyed-out part down) as visible on figure 4a, the connection site for the wire is available.

media375.png

{the spring shape allowing insertion of the conductor end when the spring is unbiased}
Definition statement

This place covers:

Electrical connections established by a leaf spring. The insertion of the wire will push the spring away from the busbar. Said otherwise, the spring is shaped to allow the insertion of the wire even if it is not pre-biased.

The following figure shows a busbar (3), a leaf spring (2) and the wire (4) that can be inserted without previously opening the spring because the spring presents an orientation allowing it.

media376.png

The following figure shows a leaf spring (25) shaped to allow the insertion of the wire (45) without pre-opening of the spring. It is mentioned that in the present case, no busbar is provided in the housing. The leaf spring is the only electrical element electrically connecting the wire (45) to the other wire (47).

media377.png

{Single-blade spring}
Definition statement

This place covers:

Leaf springs with the resilient part biasing the core of the wire, where the resilient part is made of a single resilient arm.

The following figure shows a leaf spring (3) biasing the core (14) of the wire (13) towards the busbar (15). The leaf spring has a single resilient arm biasing the wire.

media378.png

The following figure shows a leaf spring (3) biasing the wire (5) towards the busbar. The leaf spring is made of a single resilient arm.

media379.png

{Multiblade spring}
Definition statement

This place covers:

Leaf springs with the resilient part biasing the core of the wire, where the resilient part is made of a at least two resilient arms.

The following figures show a leaf spring (7) comprising three resilient arms (7c) clamping the wire between them.

media380.png

The following figure shows a leaf spring (101) comprising two different elastic members (104 and 105) both biasing the core of the wire.

media381.png

Relationships with other classification places

Leaf springs with the same blade having two opposite ends acting on two different wires are classified in groups H01R 4/4821 and H01R 11/09 (if different connecting locations are present).

In the following example, E3 and E4 are made for insertion of two different wires. Even if 3 and 4 are part of the same blade, each connection is using a single resilient blade 3 or 4. Each blade establishes a galvanic connection in the sense of H01R. Therefore the device establishes two different galvanic connections with two different wires.

media382.png

{and having a hole for the conductor, e.g. a wire, passing through}
Definition statement

This place covers:

Configurations where the wire is inserted into the electrical connection by a hole in the spring. For example, the spring usually starts parallel to the wire in a direction opposite to the insertion direction of the wire and then loops back to create a free end used for biasing the wire. In this case the hole is usually located in the part of the spring looping back.

The following figure shows a busbar (140), a leaf spring (142) and the wire (122) is inserted from the back of the leaf spring (142) at the position is loops back toward the left of the figure. The spring comprises a hole (160) receiving the wire (122).

media383.png

The following figure shows a leaf spring (131) and the wire is inserted from the back of the leaf spring (131) inside the hole (1321).

media384.png

{Spring-activating arrangements mounted on or integrally formed with the spring housing}
Definition statement

This place covers:

Details of the leaf spring activating arrangements that cannot be classified in the subgroups of the present group.

The following figures show a handle (2) mounted on the housing and used to indirectly actuate the leaf spring. This handle does not have a simple sliding or rotating movement.

media385.png

{Pivoting arrangements, e.g. lever pushing on the spring}
Definition statement

This place covers:

Leaf springs are activated by an arrangement pivoting with respect to the spring or the housing.

The following figures show a leaf spring (1) actuated by a lever (22). Further the lever biasing the leaf spring is rotating with respect to the housing (8) or the leaf spring (1).

media386.png

The following figures show a housing (2) comprising an integral rotating lever (12). This lever 12 is used for biasing opened both arms (9) of the leaf spring (3). Closed position of the spring is visible on Fig.1 and opened or biased position is visible on Fig.5.

media387.png

{Sliding arrangements, e.g. sliding button}
Definition statement

This place covers:

Leaf springs activated by an arrangement sliding with respect to the spring or the housing.

The following figures show an actuating mean 17 that is sliding left/right to bias or release the beam (16) of the leaf spring.

media388.png

The following figures show on figure 3A the activating arrangement (3) is slid up to open or bias the leaf spring (2) and allows insertion of the wire between the busbar (111) and the leaf spring (2). On figure 3B the activating arrangement (3) is slid down to close or release the leaf spring (2) thereby closing the connection site if no wire is present (case of figure 3B) or clamping the wire on the busbar if a wire would be present.

media389.png

{Mechanically bistable arrangements, e.g. locked by the housing when the spring is biased}
Definition statement

This place covers:

Activating arrangements which are mechanically stable in biased and un-biased position of the spring. Usually in the position where the activating arrangement is biasing the spring, the force of the spring tend to push the activating arrangement back, except in the case, for example, where the arrangement will be latched or locked somehow by the housing.

The following figures show an activating arrangement (15) which on figure 3 is mechanically locked behind a shoulder (141) of the housing. Because of this locking, the counter force created by the biasing of the leaf spring (12) does not slide the activating arrangement (15) back and the spring is blocked in the open position.

media390.png

The following figures show an activating arrangement (13) suitable for activating the leaf spring (12). As it is visible on figure 3, because of the flat shape (27) and the shape of (30) and the position of the hinge (29), the biased position is also a mechanically stable position for the lever (13). The user does not need to hold the lever in the open position while inserting the wire.

media391.png

{Single arrangement activating multiple springs}
Definition statement

This place covers:

Clamping devices comprising several leaf springs which are actuated by a common device.

The following figure shows a clamping device with two connection sites for two different wires (18). It further comprises a single actuating arrangement (16, greyed-out below) actuating both connection sites at the same time. Therefore, even if the spring (23) is common to both connection sites, this is not considered for the classification and only the fact that the arrangement actuates springs in at least two sites is considered.

media392.png

The following figure shows a clamping device with a single actuating arrangement (32) suitable for biasing both leaf springs (42) and (44) at the same time.

media393.png

{Spring housing details}
Definition statement

This place covers:

Details about the housing covering the leaf spring (e.g. waterproofing features, assembling elements being part of the invention).

The following figure shows a housing of the leaf spring comprising sealing members (120, greyed-out in the figure below) and special assembling elements (216) to mount several slices next to each other. Those details are both to be classified in class H01R 4/484.

media394.png

{the spring housing being provided with a single opening for insertion of a spring-activating tool}
Definition statement

This place covers:

Leaf springs with an opening in the housing to allow the insertion of a tool for biasing the leaf spring.

The following figures show a housing (50) comprising a hole (11) suitable for insertion of a tool (6) e.g. screwdriver or jig, suitable for biasing the leaf spring (51) as visible on figure 9. The activating arrangement is not part of the device, it is an additional part.

media395.png

The following figures show a tool (400) that is inserted inside the hole (118) of the housing to bias the spring (140) in the open position thereby allowing the removal of wire (310) from the busbar (130).

media396.png

Relationships with other classification places

Activating arrangements located between the tool and the leaf spring are covered by H01R 4/4828.

{the spring housing being provided with multiple openings for insertion of a spring-activating tool}
Definition statement

This place covers:

Leaf springs comprising a housing having at least two holes to allow the insertion of a tool for biasing the leaf spring from different angles.

The following figure shows two holes for inserting two different tools (22a) or (22b) in the housing from different angles.

media397.png

The following figures show a housing (12) comprising two holes (40C) and (40D) both suitable for receiving an activating arrangement (tool 44) used to act on the leaf spring (27).

media398.png

{Busbar integrally formed with the spring}
Definition statement

This place covers:

Clamping devices in which the leaf spring and the busbar are two parts of the same element. The leaf spring and busbar are both unitary.

The following figures show a leaf spring (17) and a busbar (14) made of the same metal piece. The metal piece is visible on the right before folding.

media399.png

The following figure shows a leaf spring (29 greyed-out below) and a busbar (part 31 contacting the wire, horizontal greyed-out part below) being made of the same element.

media400.png

{Single busbar common to multiple springs}
Definition statement

This place covers:

Leaf spring clamping devices comprising a common busbar to several connection sites. E.g. a clamping device suitable for shunting different wires to the same potential.

The following figure shows a single busbar (10) common to three different springs (7, 8, 9 greyed-out).

media401.png

The following figures show a single busbar (14) connecting three different connection sites for three different wires.

media402.png

{Means for improving the contact with the conductor, e.g. uneven wire-receiving surface}
Definition statement

This place covers:

Leaf spring clamping devices with the busbar presenting an uneven surface at the position connecting with the wire, usually the exact position where the leaf spring biases the wire on the busbar.

The following figure shows an uneven surface on the busbar at the position (inside the circle below) connecting to the wire (4). Those dents have the function to decrease the contact resistance between the busbar and the wire.

media403.png

The following figures show an uneven surface on the busbar at the position (inside the circle below) connecting to the wire. The dents (4,24) can have different patterns on the busbar (see left and right).
