[0039] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0040] Example 1:

[0041] A connector assembly device, reference Figure 1 , including a workbench 1, on which a pre-installation mechanism 2 and a pressing mechanism 3 are provided, and the pressing mechanism 3 is located above the pre-installation mechanism 2. A plurality of plastic shells and a corresponding number of elbow pins are placed in the pre-installation mechanism 2, and the pressing mechanism 3 is used to press the elbow pins into the corresponding plastic shells.

[0042] Four support columns 4 are fixedly connected to the workbench 1, and a fixed plate 5 is fixedly connected to the upper ends of the four support columns 4. The pressing mechanism 3 includes a pressing cylinder 301 fixedly connected to the upper end surface of the fixed plate 5. The piston rod of the pressing cylinder 301 passes through the fixed plate 5 and is fixedly connected to the pressing plate 302 at the end of the piston rod. The pressing cylinder 301 drives the pressing plate 302 to move toward or away from the pre-assembly mechanism 2.

[0043] The pressing mechanism 3 also includes two guide posts 303 fixedly connected to the upper end surface of the workbench 1. These two guide posts 303 extend through either side of the pressing plate 302. A buffer spring 6 is axially sleeved on each guide post 303. The buffer spring 6 is positioned between the pressing plate 302 and the workbench 1 to reduce the pressure exerted by the pressing plate 302 on the plastic housing and elbow pins. In other embodiments, the downward pressure of the pressing plate 302 can be adjusted by changing the type of buffer spring 6. This minimizes damage to the plastic housing and elbow pins while ensuring proper insertion of the elbow pins.

[0044] 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.

[0045] refer to Figure 2 Two limiting grooves 9 are provided on one side of the sliding seat 201 near the translation cylinder 8. Two limiting rods 10 are vertically fixed to 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.

[0046] When the translation cylinder 8 drives the sliding seat 201 to slide toward the translation cylinder 8, the two limiting rods 10 are snapped into the corresponding limiting grooves 9. When the two limiting rods 10 are squeezed with the corresponding limiting grooves 9, the sliding seat 201 is located directly below the pressing plate 302.

[0047] refer to Figure 1 Two guide blocks 202 are fixedly connected to the upper end surface of the sliding base 201. The two guide blocks 202 are respectively arranged on opposite sides of the upper end surface of the sliding base 201 near the edge. The pre-installation mechanism 2 also includes a lifting plate 204 disposed above the two guide blocks 202. The lower end surface of the lifting plate 204 has lifting slots corresponding to the positions of the two guide blocks 202. The two guide blocks 202 extend into the corresponding lifting slots.

[0048] The side walls of the two guide blocks 202 that are close to each other are fixedly connected to the limiting blocks 203. The lifting plate 204 can slide close to or away from the sliding seat 201 along the guide blocks 202, and the minimum distance between the lifting plate 204 and the sliding seat 201 is limited by the limiting blocks 203.

[0049] Four return springs 205 are fixedly connected to the upper end surface of the sliding seat 201. The four return springs 205 are set into 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.

[0050] refer to Figure 1 、 Figure 3The pre-installation mechanism 2 also includes a mold plate 206 fixedly connected to the upper end surface of the lifting plate 204. The mold plate 206 is provided with two groups of pin holes 11, each group having three pin holes. Six top posts 16 are fixedly connected to the sliding seat 201, corresponding to the pin holes 11. The top posts 16 are vertically inserted into the pin holes 11. At the same time, the top posts 16 cooperate with the inner wall of the pin cavity 11 to form a placement groove for accommodating and limiting the position of the elbow pins. The top ends of the top posts 16 support the elbow pins.

[0051] 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 two. The claws in the plastic shell extend into the fixing holes 12 and engage with the fixing holes 12.

[0052] 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.

[0053] The implementation principle of the embodiment of the present application is as follows: 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 claws of the plastic shell are clamped into the fixing hole 12.

[0054] 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.

[0055] 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 contract the return spring 205.

[0056] At the same time, the top post 16 remains stationary, so that as the mold plate 206 descends, the top of the top post 16 gradually emerges from the pin hole 11. At the same time, the top post 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.

[0057] 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 work process.

[0058] Example 2:

[0059] A connector assembly device, reference Figure 4 , including a workbench 1, the upper end surface of the workbench 1 is fixedly connected to a fixing frame 23, the upper end surface of the fixing frame 23 is fixedly connected to a mold plate 206, and the mold plate 206 in Example 2 has the same structure as the mold plate 206 in Example 1.

[0060] refer to Figure 4 、 Figure 5 Mounting slots 20 are provided on both sides of the mold plate 206. A baffle 21 is fixedly connected to the mold plate 206. The baffle 21 is in the shape of an inverted "C," with both ends of the baffle 21 extending into the corresponding mounting slots 20. A latch 22 is provided on each horizontal side of the mold plate 206. Both latches 22 penetrate the corresponding side wall of the mold plate 206 and the baffle 21 and extend into the mold plate 206.

[0061] 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. The end of the piston rod of the top cylinder 14 is fixedly connected to the top plate 15. Two guide rods 17 are fixedly connected to the workbench 1, which pass through the two 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. The top end of the guide rod 17 is fixedly connected to the lower end surface of the fixed frame 23.

[0062] refer to Figure 4 、 Figure 5 , buffer springs 6 are axially sleeved on both guide rods 17, and the 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.

[0063] A support block 18 is fixedly connected to the mold plate 206 and is arranged at the pin hole 11. A support hole 19 for passing the elbow ejector insertion end is opened on the support block 18, and the support hole 19 is open on the side facing the elbow ejector.

[0064] 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.

[0065] Subsequently, the ejection cylinder 14 is driven to slide the ejection plate 15 along the guide rod 17 toward the mold plate 206 , so that the ejection column 16 ejects the elbow pin placed above the ejection column 16 into the plastic shell.

[0066] 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 set in the support hole 19 of the support block 18, so that the insertion end of the elbow pin can be abutted 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.

[0067] After the elbow pins are assembled, the push cylinder 14 drives the push plate 15 to reset, causing the push column 16 to retract and facilitate placement of the next set of elbow pins. Subsequently, the latch 22 is opened and the baffle 21 is removed, allowing the assembled connector to be disassembled. Compared to other related technologies, this embodiment has a simpler structure and is easier to transport.

[0068] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
