At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the specification are only for the convenience of clear description, and are not used to limit the scope of the present application. The change or adjustment of the relative relationship, without substantially changing the technical content, is also considered as the scope of the present application.

[0049] As Figures 1-3 shown, the present application provides a connector welding fixture, which comprises a base support table 1, which is placed at the bottom of the entire fixture and is used to support and counterweight the entire fixture. According to actual needs, holes or supports for fixing the workbench can be provided on the base support table 1. The top of the base support table 1 is provided with a connector support mechanism 2, and the connector support mechanism 2 is installed with a connector fixing mechanism 3. The connector support mechanism 2 and the connector fixing mechanism 3 cooperate to clamp the connector.

[0050] Specifically, the connector support mechanism 2 comprises a horizontal support table 21, and the edge of the top of the horizontal support table 21 is provided with a vertical support frame 22. The connection between the vertical support frame 22 and the horizontal support table 21 is provided with a connector fixing hole 23, so that the vertical support frame 22 is in the form of a portal frame, and the connector fixing hole 23 is used to place the connector to be welded. The top of the vertical support frame 22 is provided with a lock catch hole 24 vertically downward, and the top of the vertical support frame 22 is provided with a lifting groove 25 on both sides of the lock catch hole 24.

[0051] The connector fixing mechanism 3 comprises a clamping block 31, the top of the clamping block 31 is provided with a limiting baffle 32, the clamping block 31 is inserted from the locking hole 24 and extends to the inside of the connector fixing hole 23. The bottom of the clamping block 31 can be overlapped with the top of the horizontal support table 21, so that the outer surface of the connector is pressed and clamped fixedly through the connector fixing hole 23. The two ends of the limiting baffle 32 extend to the outside of the clamping block 31, the limiting baffle 32 is penetrated by the lifting groove 25, and the lifting groove 25 can guide the clamping block 31 to move up and down in the inside of the locking hole 24. The clamping block 31 can be moved up and down stably through the lifting groove 25, and the clamping block 31 is limited to be out of the constraint of the locking hole 24.

[0052] The outer surface of all the lifting grooves 25 is also sleeved with an elastic piece 4, the elastic piece 4 is located in the upward direction of the limiting baffle 32 and applies pressure to the limiting baffle 32, so as to improve the clamping force of the clamping block 31 on the connector. At the same time, because the connector is light in weight, it is not necessary to clamp by excessive force. The clamping mode can be more convenient when clamping and taking out the connector relative to the above-mentioned fixing mode.

[0053] As shown in Figure 4 , in some embodiments, the clamping block 31 is provided with a bevel 33 at the bottom of the side surface. When the connector needs to be clamped, the connector is pressed from one side of the bevel 33 to the bevel 33 to apply force to the clamping block 31, and the clamping block 31 will move up under the action of the force of the connector, so that the connector enters the bottom of the clamping block 31 and is clamped and fixed by the clamping block 31. The connector includes various shapes, of which the rectangular and circular shapes are the most common. Therefore, the bottom of the clamping block 31 is provided with a semicircular fixing groove 35. When the connector is rectangular, the edge of the semicircular fixing groove 35 at the bottom of the clamping block 31 applies pressure to the surface of the connector to clamp it. When the connector is circular, the connector is clamped by the semicircular fixing groove 35.

[0054] As shown in Figure 3 and Figure 4 , in some embodiments, the inner wall of the two sides of the connector fixing hole 23 is provided with a support limiting rod 26, and the inside of the horizontal support table 21 is provided with a locking device mounting cavity 27, and the support limiting rod 26 and the locking device mounting cavity 27 are penetrated. The inside of the support limiting rod 26 is provided with a loosening prevention mechanism 5, one end of the loosening prevention mechanism 5 extends out of the support limiting rod 26 to limit the height of the clamping block 31. When the connector is welded, the end of the connector will be pressed by the welding tool, so that the clamping block 31 is pushed up under the action of the force of the lever principle. In order to avoid this situation, the loosening prevention mechanism 5 is used to apply a limiting force to the clamping block 31, so as to avoid the clamping block 31 from being pushed up.

[0055] As shown in Figure 4As shown, in some embodiments, the utility model clamping block 31 both sides are provided with positioning groove 34, positioning groove 34 equidistant vertical distribution.The positioning groove 34 that is set can promote the restriction between anti -unthreading mechanism 5, make clamping block 31 can be more easily be limited.

[0057] The outer surface of telescopic sleeve 52 is provided with traction rod 57 symmetrically.Lock catch 58 is two and is located on the two sides of locking device installation cavity 27.When trigger button 56 is subjected to downward pressure, traction rod 57 will slide down with the slide of telescopic sleeve 52.The one end of each lock catch 58 extends to the inside of the same side support limiting rod 26 and abuts against the positioning groove 34 on the side of clamping block 31, and the other end of lock catch 58 is connected with traction rod 57.

[0058] The up-down movement of traction rod 57 can draw lock catch 58 to swing, so that traction rod 57 is separated from positioning groove 34 to release the restriction on clamping block 31, to facilitate the lifting of clamping block 31.

[0059] As Figure 5 As shown, in some embodiments, the utility model limit slot 53 is opened on the outer surface of telescopic sleeve 52, and the end of button support rod 51 is provided with stop block 54.Stop block 54 extends to the inside of limit slot 53 to limit the rising height of telescopic sleeve 52, to avoid that telescopic sleeve 52 is separated from the constraint of button support rod 51.

[0060] Reset spring 55 is arranged in telescopic sleeve 52, and reset spring 55 applies upward thrust to telescopic sleeve 52 from the inside of telescopic sleeve 52 by elasticity.When telescopic sleeve 52 loses pressure, telescopic sleeve 52 will drive trigger button 56 to return to the initial state under the elastic force of reset spring 55, to facilitate the next pressing.Meanwhile, telescopic sleeve 52 returning to the initial state will drive traction rod 57 to rise, so that lock catch 58 restricts clamping block 31.

The upper end of curved panel 581 is provided with tongue 583. The initial state of curved panel 581 is that tongue 583 penetrates and supports limiting rod 26 and is in contact with positioning groove 34, when curved panel 581 is forced to rotate around hinged joint 582, tongue 583 enters the inside of supporting limiting rod 26 and loses the constraint of positioning groove 34, so that clamping block 31 can be lifted according to the requirement.

[0062] As shown in the drawings, Figure 6 and Figure 7 As shown in the drawings, in some embodiments, the utility model curved panel 581 is provided with inclined plate at the bottom. The side of inclined plate facing traction rod 57 is provided with inclined traction groove 584, and the end of traction rod 57 extends into the inside of inclined traction groove 584 and is limited. When traction rod 57 moves downward, because the end of traction rod 57 is limited by inclined traction groove 584, curved panel 581 can only rotate to make traction rod 57 move downward. When curved panel 581 rotates, tongue 583 moves to the inside of supporting limiting rod 26, thereby releasing the constraint of positioning groove 34, so that clamping block 31 can be freely lifted.

[0063] As shown in the drawings, Figures 1-4 As shown in the drawings, in some embodiments, the utility model horizontal support table 21 is provided with cable supporting mechanism 6 at the side, and cable supporting mechanism 6 can fix and support external cable. When welding connector, cable needs to be in contact with the contact of connector. Generally, the welder supports cable to weld.

When fixing cable, cable is clamped and fixed by cable clamping piece 62 after being expanded by pressure, and the core of cable is supported by extension bracket 61, so as to avoid that cable falls off.

[0065] The specific use process of the utility model is as follows:

[0066] Press trigger button 56, contact tongue 583 to limit positioning groove 34, so that clamping block 31 can move up and down;

[0067] The connector is pressed from one end of the clamping block 31 with the chamfered surface 33 to the clamping block 31 or directly lifts the clamping block 31, so that the connector is located at the bottom of the clamping block 31, and the connector is clamped and fixed by the pressure of the clamping block 31 on the connector, at this time, the trigger button 56 is released, and the latch tongue 583 is matched with the positioning groove 34 to limit the height of the clamping block 31, so that the connector is prevented from loosening;

[0068] The cable to be connected is fixed and limited by the cable clamping piece 62, and then the core of the cable is welded on the pin to be welded of the connector;

[0069] After welding, the cable is forced to be separated from the constraint of the cable clamping piece 62, and the trigger button 56 is pressed again to release the constraint of the clamping block 31 to take out the welded connector.
