Description

Technical Field

[0001] This utility model relates to the technical field of terminal wire harness dispensing auxiliary devices, and in particular to a terminal alignment structure for terminal wire harness dispensing. Background Technology

[0002] Currently, most dispensing fixtures for wire harness processing involve directly slotting and fixing the product (connector). For example, a terminal wire harness dispensing fixture with application number 202020046540.4 discloses multiple sets of parallel wire harness and terminal slots on the upper surface of the fixture. Each set of wire harness and terminal slots is interconnected, allowing for quick and precise positioning and dispensing of multiple terminal wire harnesses with high reliability and efficiency. While this slotting and fixing method can hold the connector within the slot for dispensing, it is too simplistic and prone to detachment or reduced connector lifespan. Furthermore, it only fixes the product and cannot align the terminals within the connector. Because there is a gap between the connector housing and its internal terminals, the terminals are in a random state. Irregularly positioned terminals may result in flared shapes between adjacent terminals, which persists after dispensing. This can lead to instability in mechanical and electrical performance during connector insertion with other connectors. Utility Model Content

[0003] The purpose of this utility model is to provide a terminal alignment structure for dispensing terminal wire harnesses. During the insertion process between the product connector and the board connector, the product connector can be fixed, and the position of the terminals in the product connector can be finely adjusted by the alignment pin, ensuring that the terminals are dispensed in the correct state, ensuring the stability of the terminals, and avoiding twisting of the terminals in the product connector during insertion or disengagement.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a terminal alignment structure for terminal wire harness dispensing, comprising:

[0005] The fixture plate has at least one positioning groove.

[0006] A board-end connector has a slot, in which at least one guiding pin is provided, and at least two opposite sides of the slot are respectively formed with a first sidewall and a second sidewall. The board-end connector is embedded in the positioning groove, and the first sidewall and the second sidewall respectively abut against the sidewall of the positioning groove to engage the board-end connector in the positioning groove.

[0007] As a further optimization, the end of the board connector protrudes from the fixture plate, facilitating insertion with the product connector.

[0008] As a further optimization, the first sidewall and / or the second sidewall are provided with abutments protruding from their bodies, the abutments abutting against the sidewall of the positioning groove.

[0009] As a further optimization, the abutment is provided in pairs, with the pair of abutments located on both sides of the second sidewall.

[0010] As a further optimization, the end of the guiding pin is provided with a guide surface.

[0011] As a further optimization, the inner wall of the slot is provided with a bottom groove, the projection of the guiding pin is located in the bottom groove, and a portion of it is embedded in the bottom groove and forms a gap with the bottom wall of the bottom groove.

[0012] As a further optimization, the fixture plate includes a base and a backing plate. The base is provided with a groove, and the backing plate is locked onto the base so that the positioning groove is formed between the backing plate and the groove. The assembly-type cooperation between the backing plate and the base facilitates the installation or removal of the plate connector.

[0013] As a further optimization, the base is provided with a locking hole, and the abutment is provided with a through hole. The abutment is fixed to the base by a bolt that passes through the through hole and extends into the locking hole; a washer is provided between the bolt and the through hole.

[0014] As a further optimization, the base includes a vertical plate and a horizontal plate disposed at one end of the vertical plate and protruding from the vertical plate. The groove is formed on the end of the vertical plate away from the horizontal plate. The adjacent side walls of the abutment plate abut against the vertical plate and the horizontal plate respectively, which can achieve stable bearing of the abutment plate.

[0015] As a further optimization, the fixture plate is provided with mounting holes, and the mounting holes are equipped with adsorption magnets, which can be easily adsorbed and positioned with the dispensing device.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. A board-end connector is set on the fixture plate. A guide pin is set inside the board-end connector. During the insertion process between the product connector and the board-end connector, the product connector can be fixed and the position of the terminals in the product connector can be finely adjusted by the guide pin. This ensures that the terminals are in the correct state when applying glue, ensuring the connection effect of the product connector itself after glue application. It can also ensure the stability of the terminals and avoid phenomena such as twisting of the terminals in the product connector.

[0018] 2. In one particular embodiment, the jig plate is assembled from a base and a backing plate, which facilitates the assembly and disassembly of the board end connector. Attached Figure Description

[0020] Figure 2 This is a structural diagram of the board-end connector of this utility model.

[0021] Figure 3 This is an exploded view of the present invention.

[0022] Figure 4 This is a structural diagram from another perspective of the present invention. Detailed Implementation

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figures 1 to 2 As shown, a terminal alignment structure for dispensing terminal wire harnesses includes a fixture plate 10 and a board-end connector 20. The fixture plate 10 has multiple positioning grooves 100, and the board-end connector 20 has a slot 200. Multiple alignment pins 22 are disposed within the slot 200. At least two opposite sides of the slot 200 are respectively formed with a first sidewall 211 and a second sidewall 212. The board-end connector 20 is embedded within the positioning groove 100, and the first sidewall 211 and the second sidewall 212 abut against the sidewalls of the positioning groove 100, securing the board-end connector 20 within the positioning groove 100. Preferably, in addition to the first sidewall 211 and the second sidewall 212, the other opposite sides of the slot 200 also have sidewalls, which, together with the first sidewall 211 and the second sidewall 212, enclose the positioning groove 100 to form a shell 21.

[0025] In this invention, the board-end connector 20 can be stably installed in the positioning groove 100 after its first sidewall 211 and second sidewall 212, which are arranged opposite to each other, are interference-fitted with the sidewall of the positioning groove 100. When using the terminal alignment structure for dispensing terminal harnesses, the terminal portion of the product connector (terminal harness) is inserted into the board-end connector 20, that is, the corresponding part on the terminal portion is embedded in the slot 200. During this process, the alignment pins 22 in the slot 200 can be embedded into a pair of adjacent terminals on the terminal portion to finely adjust the position of the terminals. Each guiding pin 22 can fine-tune the position of multiple terminals to ensure the accurate positioning of each terminal (avoiding adjacent terminals from being flared), thus guiding the terminals on the product connector. On this basis, applying adhesive can prevent the terminals from being in a random state, but rather apply adhesive in a consistent state, ensuring the connection effect after adhesive application. Moreover, after the adhesive has cured, the terminals will not twist during the process of pulling out the product connector or plugging the product connector into other connectors, ensuring the stability of the terminals and avoiding instability of the terminals that could lead to instability in mechanical and electrical performance.

[0026] In this utility model, preferably, ten to twenty positioning grooves 100 are provided on the fixture plate 10 at intervals, and ten to twenty board end connectors 20 are respectively snapped into the positioning grooves 100, which can allow multiple product connectors to be positioned at the same time, thereby improving utilization and processing efficiency.

[0027] Preferably, the end of the board-end connector 20 protrudes from the fixture plate 10, which facilitates insertion with the terminals on the product connector.

[0028] Preferably, a tab 2121 protruding from the body can be provided on the second sidewall 212. The tab 2121 abuts against the sidewall on one side of the positioning groove 100, and the first sidewall 211 abuts against the sidewall on the other side of the positioning groove 100. The tab 2121 has a sheet-like structure. Its thinner structure can more easily deform to a certain extent when it abuts against the sidewall of the positioning groove 100, thereby achieving an interference fit. Of course, a corresponding tab can also be provided on the first sidewall 211, and the tabs on the opposite sides of the outer shell 21 respectively abut against the sidewall of the positioning groove 100.

[0029] Furthermore, the abutment 2121 provided on the second side wall 212 is a pair, and the pair of abutment 2121 are respectively located on both sides of the second side wall 212, which can ensure the stability of the abutment.

[0030] Preferably, the end of the guiding pin 22 is provided with a guide surface, and its narrower end makes it easier to realize the insertion process.

[0031] In addition, a bottom groove 201 is provided on the inner wall of the slot 200. The existence of the bottom groove 201 can match the structure of the terminal part of the product connector. On the other hand, the projection of the guiding pin 22 is located in the bottom groove 201, and its part is embedded in the bottom groove 201 and forms a gap with the bottom wall of the bottom groove 201. This can ensure that the guiding pin 22 will not shift left or right during the insertion process with the product connector, thereby effectively ensuring the accurate position of the terminal in the product connector.

[0032] like Figure 3 As shown, in another embodiment of the present invention, the jig plate 10 includes a base 11 and a stop plate 12. The base 11 is provided with a groove 101, and the stop plate 12 is locked on the base 11 so that a positioning groove 100 is formed between the stop plate 12 and the groove 101. When it is necessary to engage the board end connector 20 in the positioning groove 100, the stop plate 12 is removed from the base 10 so that one side of the groove 101 is exposed. The board end connector 20 can be inserted into the groove 101 from the base 11 near the exposed side of the groove 101 on the stop plate 12. The stop plate 12 is abutted and locked on the base 11, so that one of the first side wall 211 and the second side wall 212 abuts against the side wall in the groove 101, and the other abuts against the stop plate 12 and is thus engaged on the jig plate 10. During the installation process described above, the board-end connector 20 is first positioned in the groove 101 without being snapped in. The positioning process is relatively easy. The board-end connector 20 is then fixed after being snapped in during the locking connection between the abutment plate 12 and the base 11. This method facilitates the assembly and disassembly of the board-end connector 20.

[0033] Specifically, the base 11 is provided with a locking hole 110, and the abutment 12 is provided with a through hole 120. The abutment 12 is fixed to the base 11 by bolts 13 that pass through the through hole 120 and extend into the locking hole 110. For example, two to four bolts 13 are provided, which can be quickly locked or disassembled, and the abutment 12 and the base 11 can be quickly assembled and disassembled. In addition, a washer is provided between the bolt 33 and the through hole 120, which can improve the locking stability of the bolt 33.

[0034] Furthermore, the base 11 includes a vertical plate 111 and a horizontal plate 112 disposed at one end of the vertical plate 111 and protruding from the vertical plate 111. The groove 101 is formed on the end of the vertical plate 111 away from the horizontal plate 112. The adjacent side walls of the abutment plate 12 abut against the vertical plate 111 and the horizontal plate 112 respectively, which can realize a stable connection between the abutment plate 12 and the base 11.

[0035] Combination Figure 4 As shown, the fixture plate 10 is provided with mounting holes 102. Preferably, the mounting holes 102 are provided on the base 11. The mounting holes 102 are provided with adsorption magnets 14 for matching with the assembly slot of the dispensing device. After magnetic attraction, the terminal wire harness dispensing terminal guide structure is fixed.

[0036] In addition, an auxiliary hole 103 connected to the mounting hole 102 can be provided on the base 11. When the magnet 14 is installed incorrectly in the mounting hole 102 (such as the magnetic pole direction is incorrect), the magnet 14 can be pushed out of the mounting hole 102 by a tool that passes through the auxiliary hole 103 and extends into the mounting hole 102.
