Referring to fig. 1-2, fig. 1 is a schematic three-dimensional structure diagram of a connector welding fixture according to an embodiment of the present invention; fig. 2 is a front view of fig. 1.

In a specific embodiment, the utility model provides a connector welding jig includes base 1, clamp plate 2 and compresses tightly the subassembly.

Wherein, set up a plurality of connector locating holes 7 that are used for placing the connector on the base 1, connector locating hole 7 is used for fixing a position the connector, and specific quantity sets up as required, and this here is no longer repeated. Preferably, the plurality of connector positioning holes 7 are equally distributed side by side. The shape of the connector positioning hole 7 is set corresponding to the shape of the connector. The pressing plate 2 is matched with the base 1 and used for pressing the connecting rod from the top end under the action of the pressing component. The shape of the pressure plate 2 can be set according to the requirement, and the surface of the pressure plate acting on the connecting rod is a plane.

The pressing components are respectively installed at the two ends of the base 1, and the acting ends of the pressing components are used for pressing the pressing plate 2 to the base 1 so as to tightly press the connector in the connector positioning hole 7. That is, the hold-down assembly can provide pressure to the pressure plate 2, and the pressure plate 2 in turn transmits the pressure to the connecting rod, which acts on the connector again, so that the position of the connector and the connecting rod is restricted and cannot move. The pressing component may be a component that provides pressure through the elastic member 3, or a component that provides pressure through hydraulic pressure or air pressure for a telescopic cylinder.

Use the utility model provides a connector welding jig when carrying out the welding of connector and connecting rod, place the connector in connector locating hole 7 and lay the tin cream, install clamp plate 2 in the connecting rod top after corresponding the connecting rod of having placed, and make its effect end compress tightly clamp plate 2 to base 1's direction through compressing tightly the subassembly afterwards, thereby the connector is spacing with the locating lever, even be heated can not the drunkenness yet, thereby the uniformity of size after the welding has been guaranteed, also have good welding effect to small-size connectors such as 5G.

Specifically, compress tightly the subassembly and include elastic component 3, fastener 4 and with fastener 4 sliding connection's moving part 5, the one end and the base 1 of fastener 4 are connected, the both ends of elastic component 3 offset with the other end of fastener 4 and the one end that moving part 5 deviates from clamp plate 2 respectively, moving part 5 is the effect end towards the one end of clamp plate 2. That is, the one end of fastener 4 is connected with base 1, and moving part 5 and fastener 4 sliding connection specifically can set up the through-hole on moving part 5, and fastener 4 wears to locate in the through-hole, and then moving part 5 can slide from top to bottom along fastener 4. Or the sliding connection between the movable piece 5 and the fastening piece 4 can also be realized through the matching of a sliding rail and a sliding block and the like. Two ends of the elastic element 3 respectively abut against the end surface of the fastener 4 facing the movable element 5 and the end surface of the movable element 5 departing from the pressing plate 2, so that the elastic force of the elastic element 3 pushes the movable element 5 to apply pressure to the pressing plate 2. The pressure acting on the pressure plate 2 can be specifically adjusted through the pretightening force of the elastic piece 3, so that the connector and the connecting rod are prevented from moving in the welding process.

Furthermore, the connecting height of the fastening piece 4 and the base 1 is adjustable, so that for the same elastic piece 3, the connecting position of the fastening piece 4 and the base 1 can be adjusted, and after the connector and the connecting rod are assembled, the pretightening force of the elastic piece 3 is changed along with the height change of the fastening piece 4, so that the pretightening force is adjusted. In addition, to the welding of the connector and the connecting rod of different specifications, then can be through the hookup location of adjustment fastener 4 and base 1, guarantee that the pretightning force that elastic component 3 provided can compress tightly clamp plate 2, prevent connector and connecting rod drunkenness. Therefore, the welding fixture can be suitable for welding connectors of different specifications, so that the application range of the welding fixture is wider.

Furthermore, the fastening member 4 is a screw, and two ends of the elastic member 3 respectively abut against a head of the screw and one end of the movable member 5 away from the pressing plate 2. The screw is connected with the base 1, so that the height of the screw screwed into the base 1 can be adjusted, namely, the connection position of the screw and the base 1 can be continuously adjusted, and the application range of the welding fixture is wider. And the screw is connected, only the screw needs to be rotated during adjustment, and the operation is convenient. The end surface of the screw head is adapted to engage with the resilient element 3.

Specifically, the elastic member 3 is a compression spring. When the elastic part 3 adopts the spiral spring, the spiral spring can be sleeved outside the screw, so that the screw can support and limit the spiral spring, and the deformation of the spiral spring is more stable. The elastic member 3 is not limited to a spring, and other structural members and material members capable of providing elastic restoring force may be used as needed.

If necessary, the pressure plate 2 may be provided with positioning pins 6, and the base 1 may be provided with pin holes to position the two. In order to facilitate the installation of the positioning pin 6, pin holes can be respectively formed in the base 1 and the pressing plate 2, and then the two ends of the positioning pin 6 are respectively inserted into the pin holes in the base 1 and the pressing plate 2, so that the positioning of the base 1 and the pressing plate 2 is realized. Specifically, the two ends of the base 1 can be respectively positioned with the pressure plate 2 through the matching of the positioning pin 6 and the pin hole, namely, the two ends are positioned to ensure the positioning accuracy.

Specifically, the base 1 is provided with a U-shaped groove, the connector positioning hole 7 is formed in the bottom of the U-shaped groove, and the pressing component is mounted on the end faces of two sides of the U-shaped groove. Through the setting in U-shaped groove, for the installation of connector and connecting rod provides the space, the cooperation of base 1 and clamp plate 2 of being convenient for simultaneously. The U-shaped groove can be a through groove, so that the position condition of the connecting rod can be observed conveniently from two ends.

Furthermore, two sides of the U-shaped groove are provided with two-stage step surfaces, the step surface close to the U-shaped groove is lower than the step surface on the outer side, the pressing assembly is installed on the step surface on the outer side, and the positioning pin 6 is fixed on the step surface on the inner side. Namely, the U-shaped groove is a gradually rising step surface towards two sides, and the step surface at the inner side is provided with a positioning pin 6 to be matched with the pin hole on the pressure plate 2. And when the pressing component comprises a screw, the screw is in threaded connection with the step surface on the outer side.
