Description

Technical Field

[0001] This application relates to the field of electrical technology, and in particular to a terminal crimping device for an integrated double-clamp automatic wiring system. Background Technology

[0002] Terminal blocks are widely used in various electrical equipment for connecting and disconnecting wires.

[0003] For example, utility model patent CN213905716U discloses a terminal block assembly, including a cover and at least one wiring unit; the cover has a socket; the wiring unit includes a box and a pin holder, a V-shaped spring, a handle and a rivet disposed in the box, the inner surface of the box has a cavity and a post corresponding to the socket on the cover, the outer surface has a socket corresponding to the post on the inner surface, and the side has a wire inlet hole communicating with the cavity and the outside; a wiring unit is inserted and fixed into the socket on the cover through the post on its box to form a single terminal block; multiple wiring units are sequentially inserted and fixed into the socket on the cover and the box of the previously assembled wiring unit through the post on their respective boxes to form a terminal block.

[0004] When using the above-mentioned terminal block assembly, during wiring, the handle end needs to be lifted, the handle presses down on the V-shaped spring to deform it, the wire is then inserted into the inlet hole, and the handle is released. The V-shaped spring returns to its original position and locks the wire in place, thus completing the wiring. The operator needs to coordinate the actions of "lifting the handle with one hand" and "inserting the wire with the other hand" simultaneously. The operation has a low error tolerance and may cause the timing of wire insertion to deviate, resulting in insufficient clamping reliability. This needs to be improved. Summary of the Invention

[0005] To address the aforementioned issues, this application provides an integrated double-clamp automatic wiring terminal crimping device.

[0006] This application provides an integrated double-clamp automatic wiring terminal crimping device, which adopts the following technical solution:

[0007] A terminal crimping device for automatic wiring with integrated double snap fasteners includes a handle and a spring. The spring includes a connecting part, a clamping part and a triggering part disposed on the connecting part. The clamping part and the triggering part are respectively located on both sides of the connecting part. The triggering part is provided with a snap fastener for locking the clamping part. The handle abuts against the side of the clamping part away from the connecting part.

[0008] By adopting the above technical solution, before wiring, lifting the handle causes the clamping part to deform towards the connection part by squeezing the handle. The latch then locks the clamping part in place. At this time, the spring is in the triggered state. When wiring, simply insert the wire between the handle and the clamping part. The wire passes over the clamping part and squeezes the triggering part, causing the triggering part to disengage from the clamping part. The clamping part then resets and locks the wire in place, thus completing the wiring. The operator only needs to insert the wire to trigger the clamping part to automatically clamp, making the operation more convenient, improving the error tolerance, and unaffected by deviations in the timing of wire insertion.

[0009] Optionally, the trigger part is provided with a second latch, which is located on the side of the first latch away from the connecting part. The second latch is used to lock the handle. When the second latch locks the handle, the first latch locks the clamping part.

[0010] By adopting the above technical solution and setting a second clip, the handle is positioned by clipping the handle, which makes it easier to intuitively determine whether the spring is in the triggered state, and helps to improve wiring efficiency.

[0011] Optionally, the buckle is provided with an inclined surface, which is located on the side of the buckle away from the connecting part, and the inclined surface is inclined toward the clamping part in a direction closer to the connecting part.

[0012] By adopting the above technical solution, an inclined surface is set. When the handle squeezes the clamping part, causing the clamping part to deform in the direction closer to the connecting part, the clamping part presses against the inclined surface and pushes the trigger part to deform in the direction away from the clamping part. This makes it easier for the trigger part to reset after the clamping part passes the first latch, so that the first latch locks the clamping part.

[0013] Optionally, the clamping part is provided with a force-receiving protrusion one, and the handle is provided with a force-receiving protrusion two. The handle abuts against the force-receiving protrusion one through the force-receiving protrusion two, thereby abutting against the clamping part.

[0014] By adopting the above technical solution, force-bearing protrusion one and force-bearing protrusion two are set to form a fulcrum, which makes it easy for the clamping part to deform and bend towards the connecting part under the pressure of the handle.

[0015] Optionally, the force-bearing protrusion is formed by bending the clamping portion toward the handle.

[0016] By adopting the above technical solution, the clamping part forms a corrugated plate-like concave-convex structure, which reduces stress concentration and resists local deformation.

[0017] Optionally, the clamping part and the connecting part are connected by an arc-shaped transition, and the connecting part and the triggering part are connected by an arc-shaped transition.

[0018] By adopting the above technical solution, the stress distribution of the arc transition connection is more uniform, which allows the connection between the clamping part and the connecting part, as well as the connection between the connecting part and the triggering part, to withstand repeated bending at a larger angle. The recovery ability after deformation is stronger, the elastic range is wider, and it is beneficial to extend the service life of the spring.

[0019] Optionally, the handle has a clearance groove on the side near the trigger portion, the clearance groove being for the wire to pass through.

[0020] By adopting the above technical solution, the situation where the handle squeezes the wire and thus affects the wiring is reduced.

[0021] Optionally, the handle includes a squeezing part and a handle portion disposed on the squeezing part, the squeezing part abutting against the clamping part, the handle portion being located on the side of the squeezing part away from the clamping part, and the handle portion being provided with anti-slip texture.

[0022] By adopting the above technical solution and setting anti-slip texture, the friction between the hand and the handle is increased when the hand contacts the handle, reducing the chance of slipping when the operator lifts the handle.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Before wiring, lift the handle. The handle presses against the clamping part, causing the clamping part to deform towards the connection part. The latch locks the clamping part and positions it. At this time, the spring is in the triggered state. When wiring, simply insert the wire between the handle and the clamping part. The wire passes over the clamping part and presses against the triggering part, causing the triggering part to disengage from the clamping part. The clamping part then resets and locks the wire to complete the wiring. The operator only needs to insert the wire to trigger the clamping part to automatically clamp. The operation is more convenient, the error tolerance is improved, and it is not affected by the timing deviation of wire insertion.

[0025] 2. A second latch is installed to lock the handle in place, making it easier to visually determine whether the spring is in the triggered state, which helps improve wiring efficiency;

[0026] 3. Two force-bearing protrusions are provided to form a fulcrum, which facilitates the clamping part to deform and bend towards the connecting part under the pressure of the handle. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0032] This application discloses an integrated double-clamp automatic wiring terminal crimping device. See also: Figures 1-3 The terminal crimping device for the integrated double-clamp automatic wiring includes a handle 1 and a spring 2. The spring 2 includes a connecting part 21, a clamping part 22, and a triggering part 23. The clamping part 22 and the triggering part 23 are located on opposite sides of the connecting part 21, and the clamping part 22 is inclined away from the connecting part 21 in the direction closer to the triggering part 23. The clamping part 22 and the connecting part 21 are connected by an arc-shaped transition, and the connecting part 21 and the triggering part 23 are connected by an arc-shaped transition. The connecting part 21, the clamping part 22, and the triggering part 23 are integrally set.

[0033] See Figures 1-3 The trigger part 23 is bent at both ends in the horizontal direction toward the clamping part 22. Each end of the trigger part 23 is integrally fixed with a first buckle 3 and a second buckle 4. Both the first buckle 3 and the second buckle 4 are located on the side of the trigger part 23 closer to the clamping part 22, and the second buckle 4 is located on the side of the first buckle 3 away from the connecting part 21. The first buckles 3 at both ends of the trigger part 23 are aligned in the horizontal direction, and the second buckles 4 at both ends of the trigger part 23 are aligned in the horizontal direction. A bevel 5 is formed on the outer wall of each first buckle 3. The bevel 5 is located on the side of the first buckle 3 away from the connecting part 21, and the bevel 5 is inclined toward the clamping part 22 in the direction of the connecting part 21. The first buckle 3 is used to clamp the clamping part 22.

[0034] See Figures 1-3 The handle 1 is located on the side of the clamping part 22 away from the connecting part 21. The handle 1 includes a pressing part 11 and a handle 12. The pressing part 11 has a force-bearing protrusion 6 protruding outward on the outer side wall near the clamping part 22. A clearance groove 111 is provided on the side of the pressing part 11 near the trigger part 23 for the wire to pass through. The handle 12 is located on the side of the pressing part 11 away from the clamping part 22 and is integrally fixed with the pressing part 11. Anti-slip texture 7 is formed on the outer side wall of the handle 12. The anti-slip texture 7 is located on the side of the handle 12 near the connecting part 21. The second buckle 4 is used to lock the pressing part 11. When the second buckle 4 locks the pressing part 11, the first buckle 3 locks the clamping part 22.

[0035] See Figures 1-3 The clamping part 22 is bent toward the direction of the pressing part 11 to form a force-receiving protrusion 8. The pressing part 11 abuts against the force-receiving protrusion 8 through the force-receiving protrusion 26, thereby abutting against the side of the clamping part 22 away from the connecting part 21.

[0036] The implementation principle of the terminal crimping device for integrated double-clamp automatic wiring in this application embodiment is as follows:

[0037] Before wiring, lift the handle 12. The handle 12 drives the squeezing part 11 to squeeze the clamping part 22, causing the clamping part 22 to deform towards the connecting part 21. The latch 3 locks the clamping part 22 and positions it. At this time, the spring 2 is in the triggered state. When wiring, simply insert the wire between the squeezing part 11 and the clamping part 22. The wire passes over the clamping part 22 and squeezes the trigger part 23, causing the trigger part 23 to disengage from the clamping part 22. The clamping part 22 then resets and locks the wire to complete the wiring. When wiring, the operator only needs to insert the wire to trigger the clamping part 22 to automatically clamp. This makes the operation more convenient, improves the error tolerance, and is not affected by the timing deviation of wire insertion.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
