[0022] Please see Figure 1-5 The present invention provides an embodiment of an easy-to-disassemble connector, including a terminal housing 1 and an inner terminal housing 2 inside the terminal housing 1. The inner terminal housing 2 is a centrally symmetrical split structure design, that is, the inner terminal housing 2 is composed of two symmetrical upper and lower half-inner housing structures. When the half-inner housing structures are closed, they form the inner terminal housing 2 assembly. It can also be separated, so as to facilitate the separation and opening of the interior of the inner terminal housing 2, and facilitate the quick opening and maintenance of the internal structure.

[0023] The terminal housing 1 is slidably fitted onto the outside of the terminal inner housing 2. After assembly, both the terminal housing 1 and the terminal inner housing 2 have aligned positioning holes inside. A retainer 8 is fixedly installed on one outer wall of the terminal housing 1, and a snap-fit ​​member 9 is inserted into the positioning hole. For details, please refer to the attached instruction manual. Figure 4 As shown, the snap-fit ​​component 9 adopts an arched structure design;

[0024] For further details, please refer to the appendix to the instruction manual. Figure 2 As shown, the card head 10 adapted to the card seat 8 is fixedly installed on both sides of the tail end of the card connector 9. The inner shell 2 of the terminal is provided with a limit post 6, and the limit post 6 is sleeved with a conductive contact piece 7.

[0025] With this structural design, when it is necessary to assemble the terminal head structure, the conductive contact 7 can be sleeved on the limiting post 6, and then the other half of the inner shell of the terminal inner shell 2 can be placed on top of the conductive contact 7. In this way, the closed assembly between the two half inner shell structures can be completed, thus forming a complete structural assembly of the terminal inner shell 2.

[0026] After the terminal inner shell 2 and the conductive contact 7 are assembled, the terminal outer shell 1 is slidably fitted onto the outside of the terminal inner shell 2 assembly. After the fitting is completed, the terminal outer shell 1 and the terminal inner shell 2 are aligned with each other through the positioning holes. Then, the snap-fit ​​component 9 for fixing the housing is installed in the positioning holes.

[0027] After the snap-fit ​​9 is inserted into the positioning hole, the snap-fit ​​head 10 at one end can be manually pressed and snapped onto the outside of the snap-fit ​​seat 8. In this way, the snap-fit ​​9 can be fixedly installed in the terminal housing 1 and the terminal inner housing 2 through the snap-fit ​​9, thereby completing the fixed connection between the housing and the inner housing. At this time, the assembly of the terminal head is completed.

[0028] When it is necessary to disassemble the terminal head, the clip 10 can be pushed out of the clip seat 8 by using a cylindrical tool such as a screwdriver. Then the clip 9 can be pulled out, and the clip 9 can be pulled out from the two housings. After that, the terminal housing 1 can be slid off the terminal inner housing 2.

[0029] The split-type terminal inner shell 2, without the enclosure and restraint of the terminal outer shell 1, can be separated into two halves by manual prying, thereby opening the terminal inner shell 2 and completing the quick disassembly of the terminal head. It has the characteristics of easy assembly and disassembly.

[0030] In this embodiment, in order to facilitate the clamp-type power connection process, the upper and lower ends of the front side of the terminal inner shell 2 are provided with claw discs 3. Claw grooves are opened on the claw discs 3, and power connection claws 4 are placed in the claw grooves of the claw discs 3. Each power connection claw 4 is clamped with an elastic metal piece 5.

[0031] This structural design allows the set electrical contact claws 4 to contact external conductive structures. The opposing upper and lower electrical contact claws 4 ensure normal clamping and electrical contact operation, and ensure normal electrical conduction effect.

[0032] The present invention has an elastic metal sheet 5 on the power receiving claw 4. When the power receiving claw 4 clamps the external conductor, it will abut against the elastic metal sheet 5 to cause a certain deformation. The deformed elastic metal sheet 5 has a certain elasticity. In this way, the conductor between the power receiving claw 4 can be clamped by the elastic rebound force of the metal sheet.

[0033] When the terminal head is pulled out, the power clamp 4 can spring back and reset under the action of the elastic metal sheet 5, thereby achieving a certain structural reset effect and ensuring the clamping and reset usability of the terminal head of this utility model.

[0034] In this embodiment, in order to ensure the conductivity of the battery cell in the terminal head, the tail ends of several connecting claws 4 are in electrical conductive contact with the conductive contact 7. One end of the conductive contact 7 extends out of the housing, and a through hole is provided on the outer surface of the conductive contact 7. The through hole can be used to wrap external electrical wires, thereby ensuring the normal wire harness connection of the terminal head.

[0035] When the power-connecting claw 4 clamps the conductive plate, the power-connecting claw 4 can transmit electrical signals to the conductive contact 7. Thus, when the conductive wire harness is wound on the conductive contact 7, it can perform normal electrical conduction through the terminal head of this utility model.

[0036] Working principle: When in use, the conductive contact 7 of this utility model can be connected to an external electrical wire, thereby ensuring the normal wiring harness connection of the terminal head.

[0037] In practical use, the terminal head of this utility model can be inserted into the matching terminal slot. The set power-connecting claws 4 can clamp and contact with the conductive structure of the terminal slot. In this way, the upper and lower opposing power-connecting claws 4 can ensure normal clamping and power-connecting operation and ensure normal electrical conduction effect.

[0038] When the power-connecting claw 4 clamps the conductive structure of the terminal slot, the power-connecting claw 4 can transmit the electrical signal to the conductive contact 7. Thus, when the conductive wire harness is wound on the conductive contact 7, it can carry out normal electrical conduction through the terminal head of this utility model, ensuring normal use.

[0039] The present invention has an elastic metal sheet 5 on the power receiving claw 4. When the power receiving claw 4 clamps the external conductor, it will abut against the elastic metal sheet 5 to cause a certain deformation. The deformed elastic metal sheet 5 has a certain elasticity. In this way, the conductor between the power receiving claw 4 can be clamped by the elastic rebound force of the metal sheet.

[0040] When the terminal head is pulled out, the power clamp 4 can spring back and reset under the action of the elastic metal sheet 5, thereby achieving a certain structural reset effect and ensuring the clamping and reset usability of the terminal head of this utility model.

[0041] When it is necessary to assemble the terminal head structure, the conductive contact 7 can be sleeved on the limiting post 6, and then the other half of the inner shell of the terminal inner shell 2 can be placed on top of the conductive contact 7. This completes the closed assembly between the two half inner shell structures, forming a complete terminal inner shell 2 structure assembly.

[0042] After the terminal inner shell 2 and the conductive contact 7 are assembled, the terminal outer shell 1 is slidably fitted onto the outside of the terminal inner shell 2 assembly. After the fitting is completed, the terminal outer shell 1 and the terminal inner shell 2 are aligned with each other through the positioning holes. Then, the snap-fit ​​component 9 for fixing the housing is installed in the positioning holes.

[0043] After the snap-fit ​​9 is inserted into the positioning hole, the snap-fit ​​head 10 at one end can be manually pressed and snapped onto the outside of the snap-fit ​​seat 8. In this way, the snap-fit ​​9 can be fixedly installed in the terminal housing 1 and the terminal inner housing 2 through the snap-fit ​​9, thereby completing the fixed connection between the housing and the inner housing. At this time, the assembly of the terminal head is completed.

[0044] When it is necessary to disassemble the terminal head, the clip 10 can be pushed out of the clip seat 8 by using a cylindrical tool such as a screwdriver. Then the clip 9 can be pulled out, and the clip 9 can be pulled out from the two housings. After that, the terminal housing 1 can be slid off the terminal inner housing 2.

[0045] The split-type terminal inner shell 2, without the enclosure and restraint of the terminal outer shell 1, can be separated into two halves by manual prying, thereby opening the terminal inner shell 2 and completing the quick disassembly of the terminal head. It has the characteristics of easy assembly and disassembly.

[0046] Based on the above description, the connector of this utility model allows for convenient and rapid assembly and disassembly of its internal components during actual use. It features easy assembly and disassembly, making it easy to use. Compared to traditional encapsulated connector structures, the detachable, split structure of this utility model allows for targeted opening and repair when internal faults occur, effectively improving the overall maintenance and repair efficiency of the connector. The structure is more convenient to use, effectively reducing usage limitations and avoiding the drawbacks of traditional connectors requiring disposal after damage. This improves structural utilization efficiency, avoids structural waste, and demonstrates better practical application and greater usability.
