[0031] The pressing mechanism 3 also includes two guide posts 303 fixedly connected to the upper end surface of the workbench 1, and the two guide posts 303 are respectively arranged on both sides of the pressing plate 302. The two guide posts 303 are axially sleeved with a buffer spring 6, which is arranged between the pressing plate 302 and the workbench 1, and is used to reduce the pressure of the pressing plate 302 on the plastic shell and the elbow pin. In other embodiments, the downward pressure of the pressing plate 302 can be adjusted by changing the model of the buffer spring 6, and the plastic shell and the elbow pin can be avoided as much as possible while ensuring the normal insertion of the elbow pin.

[0032] The upper end surface of the workbench 1 is provided with a sliding groove 7, and the pre-installation mechanism 2 includes a sliding seat 201 slidably arranged in the sliding groove 7. A translation cylinder 8 is fixedly connected to the side of the workbench 1 away from the opening of the sliding groove 7, and the piston rod of the translation cylinder 8 is fixedly connected to the side wall of the sliding seat 201.

[0033] refer to Figure 2 Two limiting grooves 9 are provided on one side of the sliding seat 201 close to the translation cylinder 8, and two limiting rods 10 are vertically fixed on the upper end surface of the workbench 1, and the positions of the two limiting rods 10 correspond to the limiting grooves 9. In addition, a through hole is provided on the pressing plate 302 for the two limiting rods 10 to pass through.

[0034] When the translation cylinder 8 drives the sliding seat 201 to slide toward the translation cylinder 8, the two limiting rods 10 are inserted into the corresponding limiting grooves 9. When the two limiting rods 10 are pressed against the corresponding limiting grooves 9, the sliding seat 201 is located directly below the pressing plate 302.

[0035] refer to Figure 1 The upper end surface of the sliding seat 201 is fixedly connected with two guide blocks 202, and the two guide blocks 202 are respectively arranged on both sides of the upper end surface of the sliding seat 201 near the edge. The pre-installation mechanism 2 also includes a lifting plate 204 arranged above the two guide blocks 202, and the lower end surface of the lifting plate 204 is provided with lifting grooves corresponding to the positions of the two guide blocks 202, and the two guide blocks 202 extend into the corresponding lifting grooves respectively.

[0036] The side walls of the two guide blocks 202 close to each other are fixedly connected with the limiting blocks 203. The lifting plate 204 can slide along the guide blocks 202 close to or away from the sliding seat 201, and the limiting blocks 203 limit the shortest distance between the lifting plate 204 and the sliding seat 201.

[0037] Four return springs 205 are fixedly connected to the upper end surface of the sliding seat 201. The four return springs 205 are arranged in two groups and are respectively arranged on both sides of the lower end surface of the lifting plate 204. The top ends of the four return springs 205 are fixedly connected to the lower end surface of the lifting plate 204.

[0038] refer to Figure 1 , Figure 3 The pre-installation mechanism 2 also includes a mold plate 206 fixedly connected to the upper end surface of the lifting plate 204. Two groups of pin holes 11 are opened on the mold plate 206, and the number of each group is set to three. Six top pillars 16 corresponding to the pin holes 11 are fixedly connected to the sliding seat 201, and the top pillars 16 are vertically penetrated in the pin holes 11. At the same time, the top pillars 16 and the inner wall of the pin hole 11 cooperate to form a placement groove for placing and limiting the elbow pin, and the top of the top pillar 16 carries the elbow pin.

[0039] The two opposite side walls of the plastic shell are integrally formed with claws, and the mold plate 206 is provided with two groups of fixing holes 12, each group of which is set to two. The claws in the plastic shell extend into the fixing holes 12 accordingly and are engaged with the fixing holes 12.

[0040] Each group of fixing holes 12 and pin holes 11 corresponds to the installation of a plastic shell and a corresponding elbow pin. In other embodiments, the fixing holes 12 and pin holes 11 can be set to multiple groups of other numbers.

[0041] The implementation principle of the embodiment of the present application is: when assembling the elbow pin and the plastic shell on the mold, the elbow pin is first placed on the top column 16 in the pin hole 11, and at this time the height of the top column 16 is lower than the upper surface of the mold plate 206, and then the claw of the plastic shell is inserted into the fixing hole 12.

[0042] After completion, the sliding seat 201 is driven to slide to the bottom of the pressing plate 302 by driving the translation cylinder 8, and then the mold plate 206 is moved to the bottom of the pressing plate 302 through the cooperation of the two limiting rods 10 and the two limiting grooves 9.

[0043] Secondly, the pressing cylinder 301 is driven to move the pressing plate 302 toward the plastic shell. When the pressing plate 302 begins to squeeze the plastic shell and pushes the lifting plate 204 toward the sliding seat 201, the plastic shell, the mold plate 206, and the lifting plate 204 move closer to the sliding seat 201, and further shrink the return spring 205.

[0044] At the same time, the top column 16 remains stationary, so that as the mold plate 206 descends, the top of the top column 16 gradually emerges from the pin hole 11. At the same time, the top column 16 remains stationary so that the elbow pin also remains stationary, thereby achieving relative displacement between the elbow pin and the plastic shell, allowing the elbow pin to be inserted into the plastic shell.

[0045] After the insertion is completed, the pressing cylinder 301 drives the pressing plate 302 to reset, and the reset spring 205 is released to reset the lifting plate 204, so that the top column 16 is re-immersed in the pin hole 11 for placing the elbow pin in the next working process.

[0046] Embodiment 2: A connector assembly device, reference Figure 4 , including a workbench 1, a fixing frame 23 is fixedly connected to the upper end surface of the workbench 1, a mold plate 206 is fixedly connected to the upper end surface of the fixing frame 23, and the mold plate 206 in Example 2 has the same structure as the mold plate 206 in Example 1.

[0047] refer to Figure 4 , Figure 5 , both sides of the mold plate 206 are provided with mounting grooves 20, and a baffle 21 is fixedly connected to the mold plate 206, and the baffle 21 is in an inverted "C" shape, and both ends of the baffle 21 extend into the corresponding mounting grooves 20. A latch 22 is provided on both horizontal sides of the mold plate 206, and the two latches 22 penetrate the side wall of the mold plate 206 and the baffle 21 on the corresponding side and extend into the mold plate 206.

[0048] refer to Figure 4 The upper end surface of the workbench 1 is provided with a clearance groove, in which a top cylinder 14 is fixedly connected, and the end of the piston rod of the top cylinder 14 is fixedly connected to a top plate 15. Two guide rods 17 are fixedly connected to the workbench 1 and pass through both ends of the top plate 15, respectively. The two guide rods 17 are respectively arranged on both sides of the piston rod of the top cylinder 14, and the top end of the guide rod 17 is fixedly connected to the lower end surface of the fixed frame 23.

[0049] refer to Figure 4 , Figure 5 , buffer springs 6 are axially sleeved on both guide rods 17, and buffer springs 6 are arranged between the top plate 15 and the fixing frame 23. Top columns 16 corresponding in number and position to the pin holes 11 are fixedly connected to the top plate 15, and the top columns 16 extend into the pin holes 11.

[0050] A support block 18 is fixedly connected to the mold plate 206. The support block 18 is arranged at the pin hole 11. A support hole 19 for passing the insertion end of the elbow ejector pin is opened on the support block 18. The support hole 19 is open on the side facing the elbow ejector pin.

[0051] The implementation principle of the embodiment of the present application is: after placing the elbow pin and the plastic shell on the mold plate 206, the two ends of the baffle 21 are inserted into the installation groove 20 and the baffle 21 is fixed by the pin 22.

[0052] Subsequently, the push cylinder 14 is driven to make the push plate 15 slide along the guide rod 17 toward the mold plate 206, so that the push column 16 pushes the elbow pin placed above the push column 16 into the plastic shell.

[0053] In order to avoid the position of the elbow pin and the plastic shell from being offset when the elbow pin is pushed into the plastic shell, the insertion end of the elbow pin is arranged in the support hole 19 of the support block 18, so that the insertion end of the elbow pin can be against the inner wall of the support hole 19 away from the opening and the two opposite inner walls when inserted into the plastic shell.

[0054] After the elbow pin is assembled, the top cylinder 14 drives the top plate 15 to reset, so that the top column 16 retracts, which is convenient for placing the elbow pin for the next round of work. Then, the latch 22 is opened and the baffle 21 is pulled out to disassemble the assembled connector. Compared with other related technologies, this embodiment has a simple structure and is convenient for transportation.
