Description

Technical Field

[0001] This utility model relates to the field of wire harness assembly technology, and in particular to a wire harness connector snap-fit ​​device. Background Technology

[0002] Currently, most wiring harness connectors inside automotive lights are manually clamped. During assembly, the various electrical components are manually connected using the wiring harness. Due to size and cost limitations, wiring harness connectors are generally small, making automated assembly impossible; manual clamping is the most common method. Typically, the connector is first inserted into the interface, then the connector is pressed firmly into the interface until the plug and clip are fully engaged. However, when operating space is limited and the clamping workload is large, this process becomes difficult for operators, time-consuming, labor-intensive, inefficient, and hinders production output. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a wire harness connector clamping device, which can solve the problem of wire harness clamping difficulty in small spaces, and can facilitate operation by operators and improve efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A wire harness connector clamping device includes a handle, a first pawl disposed at the front of the handle, a second pawl rotatably disposed at the middle of the handle, and a rotary handle rotatably disposed at the rear of the handle;

[0006] Rotating the handle can push the second jaw forward to rotate, and the second jaw clamps with the first jaw to secure the wire harness connector.

[0007] A spring for resetting is provided between the first and second jaws.

[0008] Furthermore, a positioning pin is provided on the side of the first and second jaws that are close to each other, and the spring is sleeved on the two positioning pins with its front and rear ends tightly attached to the first and second jaws, respectively.

[0009] Furthermore, threaded blind holes are provided on the side of the first and second jaws that are close to each other, and the positioning pin is assembled in the threaded blind holes.

[0010] Furthermore, the upper part of the first claw is mounted on the handle via two pins, the top of the second claw is rotatably mounted on the handle via a single pin, and the front part of the throttle is rotatably mounted on the handle via a single pin.

[0011] Furthermore, both the first and second claws have openings at their bottoms for avoiding the wire harness.

[0012] Furthermore, the width of the opening is greater than the diameter of the wire harness, and the widths of the first and second claws are less than the width of the wire harness connector.

[0013] Furthermore, the front end of the throttle and the rear side of the second chuck are fitted with an inclined surface.

[0014] Furthermore, the handle has a U-shaped shell structure.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] 1. This utility model, through the design of a handle, a first jaw, a rotating second jaw, and a rotating handle, allows the second jaw to be rotated simply by gripping the handle when inserting the wire harness connector. This rotation, in turn, works with the first jaw to clamp the wire harness connector, making it easy to insert the connector into the interface. This makes the operation more labor-saving and efficient, and is suitable for large-volume insertion tasks.

[0017] 2. The first and second claws of this utility model are small in size and can be inserted into narrow spaces inside the lamp for operation, making it more convenient and faster to plug in in places with limited space. Attached Figure Description

[0024] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0025] like Figure 1-5As shown, in this embodiment, a wire harness connector clamping device is provided, which mainly consists of a handle 1, a first clamping claw 2, a second clamping claw 3, a throttle 4, and a spring 5. The handle 1 has a U-shaped shell structure. The first clamping claw 2 is located at the front of the handle 1, and its upper part is positioned and installed inside the handle 1 via two pins 7. The second clamping claw 3 is located in the middle of the handle 1, and its top is rotatably installed inside the handle 1 via a single pin 7. The throttle 4 is located at the rear of the handle 1, and its front part is rotatably installed inside the handle 1 via a single pin 7. When the throttle 4 is rotated and held, the front end of the throttle 4 can push the second clamping claw 3 forward, thereby clamping the second clamping claw 3 with the first clamping claw 2 to secure the wire harness connector.

[0026] To achieve reset each time, this embodiment includes a spring 5 between the first jaw 2 and the second jaw 3. Specifically, threaded blind holes 201 are provided on the sides of the first jaw 2 and the second jaw 3 that are close to each other. Positioning pins 6 are fitted into each of the two threaded blind holes 201, and the spring 5 is sleeved on the two positioning pins 6, with its front and rear ends respectively in close contact with the first jaw 2 and the second jaw 3. Each time the handle 4 is gripped and rotated, the front end of the handle 4 pushes the second jaw 3 forward, causing it to rotate. The second jaw 3 compresses the spring 5. When the handle 4 is released, the spring 5 causes the second jaw 3 to reset. (Reference) Figure 4 As shown, it is preferable to design the front end of the throttle 4 and the rear side of the second claw 3 as an inclined surface to make it more labor-saving.

[0027] In addition, in order to avoid the wire harness during insertion, this embodiment has an opening 200 at the bottom of both the first claw 2 and the second claw 3, and the width of the opening 200 is greater than the diameter of the wire harness. The width of the first claw 2 and the second claw 3 is smaller than the width of the wire harness connector, so as to ensure that the wire harness connector is pressed tightly without interfering with other components.

[0028] refer to Figure 1-5As shown, taking lamp 9 as an example, it is placed and positioned on fixture 8. Now, it is necessary to connect the wire harness connectors at one or both ends of the driver 10 inside lamp 9. Using the snap-fit ​​device of this embodiment, the wire harness connectors at one or both ends can be pre-installed and inserted into the interface at the end of driver 10. Then, the first claw 2 and the second claw 3 of the snap-fit ​​device are respectively inserted into the two ends of driver 10. The lower part of the first claw 2 abuts against the front end of driver 10, and the lower opening 200 of the second claw 3 avoids the wire harness. Even if the wire harness is inserted into the opening 200, and the lower part of the second claw 3 abuts against the outer end of the wire harness connector, then the second claw 3 can be rotated by gripping and turning the handle 4. It cooperates with the first claw 2 to clamp and press the wire harness connector forward and insert it into the interface at the end of driver 10. Similarly, if there are wire harness connectors at both ends that need to be plugged in, the lower part of the first claw 2 abuts against the outer end of the front wire harness connector, and the lower opening 200 of the first claw 2 also avoids the wire harness. The lower part of the second claw 3 abuts against the outer end of the rear wire harness connector. Then, the same operation can be performed to press the wire harness connectors on both sides into the interfaces at both ends of the driver 10.

[0029] As can be seen from the above design, when inserting the wire harness connector, this embodiment only requires gripping the handle 4 to rotate the second claw 3, which then cooperates with the first claw 2 at the front end to generate a clamping force on the wire harness connector, allowing the connector to be easily inserted into the interface. This makes the operation more labor-saving and efficient, suitable for large-volume insertion tasks. At the same time, the first claw 2 and the second claw 3 are small in size, allowing them to be inserted into narrow spaces inside the light fixture for operation, making insertion more convenient and faster in locations with limited space.
