DETAILED DESCRIPTION

[0029] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments and drawings, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0030] Example 1: See Figure 1-Figure 4 The purpose of this embodiment is to provide a welding fixture for a circular electrical connector. The fixture body 1 of the welding fixture includes two clamping blocks 11 arranged opposite to each other, one end of the two clamping blocks 11 is hinged by a rotating shaft 12, and the other end is provided with a first card slot 16; the first card slot 16 is a triangular slot, and the extension direction of the bottom of the first card slot 16 is parallel to the rotating shaft 12; the two first card slots 16 are arranged opposite to each other and are used to clamp the circular electrical connector.

[0031] Each clamping block 11 is provided with a rotatably connected pin shaft 13, and the pin shaft 13 is parallel to the rotating shaft 12; the sliding rod 131 simultaneously passes through the two pin shafts 13 and is slidably connected with the two pin shafts 13, and the sliding rod 131 also passes through the two clamping blocks 11, and there is a sufficient gap between the sliding rod 131 and the clamping block 11 for the sliding rod 131 to swing; a limit block 132 is provided on the sliding rod 131, and the limit block 132 is slidably connected with the sliding rod 131, and a first threaded knob 134 is also provided on the limit block 132, and the limit block 132 and the sliding rod 131 can be fixed by tightening the first knob 134. A spring 133 is provided between the limit block 132 and the nearest clamping block 11, and the spring 133 applies elastic force to the clamping block 11, so that the two clamping blocks 11 are clamped.

[0032] A pressing handle 14 is fixedly provided at the end of one clamping block 11 close to the rotating shaft 12, and a connecting handle 15 is fixedly provided at the end of the other clamping block 11 close to the rotating shaft 12. By pressing the pressing handle 14 to make it close to the connecting handle 15, the clamp body 1 will open; after the circular electrical connector is placed between the two first clamping grooves 16, the pressing handle 14 is released, and the clamping block 11 will clamp the circular electrical connector under the action of the spring 133. At the same time, by adjusting the position of the limit block 132, the elastic force of the spring 133 can be adjusted. Therefore, when the clamp body 1 is clamping circular electrical connectors of different sizes, the limit block 132 can be adjusted to make the clamp body 1 have a suitable clamping force.

[0033] A side of the pressing handle 14 facing away from the connecting handle 15 is provided with an anti-slip surface.

[0034] At the same time, the clamping block 11 is provided with a second slot 17 at the end away from the rotating shaft 12. The second slots 17 are all triangular slots, and the bottom of the second slot 17 extends toward the rotating shaft 12. The two second slots 17 are arranged opposite to each other. The size of the second slot 17 is smaller than the first slot 16. Therefore, some small-sized circular electrical connectors can be clamped by the second slot 17.

[0035] A gasket 135 is further provided between the spring 133 and the clamping block 11, and the gasket 135 is slidably connected to the slide bar 131. The provision of the gasket 135 can prevent the spring 133 from directly contacting the clamping block 11 and damaging the contact surface of the clamping block 11.

[0036] The clamp body 1 can be connected to the fixed support member through the connecting handle 15. A screw hole is arranged in the free end of the connecting handle 15, and the axis of the screw hole is parallel to the connecting handle 15; a second knob 151 is arranged in cooperation with the screw hole.

[0037] Example 2: See Figure 5 The welding fixture of a circular electrical connector provided in this embodiment has the following improvements compared with the embodiment 1:

[0038] The fixed support member includes a bottom plate 2 and a vertical plate 3 vertically fixedly connected to the bottom plate 2. A vertical slide groove 31 is provided on the vertical plate 3. The outer diameter of the screw rod of the second knob 151 is slightly smaller than the groove width of the slide groove 31, so the second knob 151 can slide along the slide groove 31. After the second knob 151 passes through the slide groove 31 and is threadedly connected to the connecting handle 15, the second knob 151 is tightened to fix the clamp body 1 and the vertical plate 3.

[0039] In this embodiment, the clamp body 1 can slide up and down along the vertical plate 3, so the use height can be adjusted as needed; the clamp body 1 can also rotate along the second knob 151, so the deflection angle in the vertical direction can be adjusted as needed.

[0040] Example 3: See Figure 6 The welding fixture of a circular electrical connector provided in this embodiment has the following improvements compared with the embodiment 1:

[0041] The fixed support member includes a bottom plate 2 and a vertical pole 4 fixedly connected to the bottom plate 2. A sliding block 41 is provided on the vertical pole 4. The sliding block 41 can be fixed to the vertical pole 4 by a third knob 43 connected by a thread. A mounting plate 42 is fixedly provided on the sliding block 41. The mounting plate 42 is provided with a through hole with a horizontal axis. The outer diameter of the screw rod of the second knob 151 is slightly smaller than the aperture of the through hole. After the screw rod of the second knob 151 passes through the through hole and is threadedly connected to the connecting handle 15, the second knob 151 is tightened to fix the clamp body 1 and the sliding block 41.

[0042] In this embodiment, the clamp body 1 can slide up and down along the vertical pole 4, so the use height can be adjusted as needed; the clamp body 1 can also rotate along the second knob 151, so the deflection angle in the vertical direction can be adjusted as needed; the clamp body 1 can also rotate along the vertical pole 4, so the deflection angle in the horizontal direction can be adjusted as needed.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
