[0021] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0022] This application discloses a fixture for assembling electrical connectors. For example... Figure 1 , 3 As shown in Figure 4, the device includes a frame 1 for housing electrical connectors. A mounting base 2, rectangular in shape, is bolted to the frame 1. Two mounting bases 2 are symmetrically arranged about the center line of the frame 1. A through hole 3, penetrating the thickness direction of the mounting base 2, is located in the middle of the mounting base 2 and is rectangular in shape. A rotating base 4, with a U-shaped cross-section, is rotatably connected within the through hole 3. Multiple rotating bases 4 are evenly spaced along the length of the mounting base 2. A rotating shaft 16 is threaded onto the mounting base 2. A circular recessed groove 17, with an interference fit bearing for the rotating shaft 16, is located in the middle of each rotating base 4. A fixing rod 5 is slidably connected within each rotating base 4. Two opposite sidewalls of the rotating base 4 have protrusions 18, rectangular in shape. The fixing rod 5 has a slide rail 19 that mates with the protrusions 18 and is coated with grease. A through groove 6 is provided at the end of the fixing rod 5 away from the fixing base 2. A connecting strip 7 is provided in the through groove 6 on the fixing rod 5 within the same fixing base 2. When the two connecting strips 7 cover the outer wall of the circular electrical connector and are fixed at their intersection, the electrical connector will be fixed on the frame 1. Both ends of the two connecting strips 7 are slidably connected to clips 8 for fixing the two connecting strips 7. The clips 8 are used to fix the connecting strips 7 to the outer wall of the electrical connector. The clips 8 are prior art. A push rod motor 20 is fixed on the fixing base 2 by mounting bolts. The fixing base 2 is provided with a round hole. The output shaft of the push rod motor 20 extends through the round hole to the through hole 3 and is keyed to a fixing plate 21. When the push rod motor 20 is working, the fixing plate 21 presses against the fixing rod 5 to prevent the fixing rod 5 from rotating.

[0023] In one embodiment, according to the appendix Figure 2As shown, the end of the fixed rod 5 is provided with a positioning end 9, the through groove 6 is located on the positioning end 9, the positioning end 9 is glued with a rubber pad 10 in contact with the shell of the electric connector, and the rubber pad 10 is in the shape of an isosceles trapezoid. The through groove 6 is provided with a spring 13 near one end of the fixed rod 5, one end of the spring 13 is clamped with a pressing plate 11, and the pressing plate 11 is in the shape of a rectangular plate. The two opposite faces of the positioning end 9 are provided with grooves 12, the grooves 12 are provided with screw rods 14 extending into the through groove 6, and the positioning end 9 is provided with screw holes for connecting the grooves 12 and the through groove 6. When the screw rod 14 pushes the pressing plate 11 to move, the positioning end 9 will be fixed with the connecting belt 7 under the action of the pressing plate 11.

[0024] In an embodiment, according to the attached Figure 4 As shown, the connecting belt 7 is provided with a scale, and the scale extends to both ends along the middle position of the connecting belt 7.

The circle where the clamping groove is located is concentric with the circle where the rotating shaft 16 is located. The clamping groove is glued with an angle ruler 15 for observing the rotation angle of the rotating seat 4.

[0025] The implementation principle of the electric connector assembly clamp of the embodiment is as follows: the worker adjusts the length of the connecting belt to be appropriate by referring to the scale on the connecting belt and pulling the connecting belt corresponding to the two fixed seats with both hands according to the diameter of the electric connector to be assembled, so that the circumference of the connecting belt is slightly larger than the outer diameter of the electric connector, and a proper allowance is reserved for subsequent fixation. The electric connector is placed between the two fixed seats of the rack, the rotating seat drives the fixed rod to swing flexibly at multiple angles, the rubber pad of the positioning end of the fixed rod is gently attached to the circumference of the outer wall of the electric connector, the screw rod is rotated, the screw rod pushes the pressing plate to move stably against the spring force, until the pressing plate is tightly compacted, the pushing rod motor on the fixed seat is started, and the fixed plate extrudes the fixed rod to fix the angle of the fixed rod.
