[0002] In the field of electronic device connectivity, connectors, as key components for achieving circuit continuity, directly impact the ease of use and maintenance efficiency of the equipment due to the rationality of their structural design. Currently, most connectors widely used in the market adopt an integrated housing structure, fixing the conductive terminal module inside the housing. This traditional design has revealed many problems in practical use: when the connector malfunctions or requires maintenance, the housing structure is difficult to disassemble, often requiring the use of specialized tools for forced removal. This is not only cumbersome and time-consuming, but also easily damages the housing or the internal conductive terminal module, thereby affecting the connector's performance and lifespan.

[0003] Furthermore, in existing connectors, when it is necessary to replace or repair the conductive terminal module, the entire connector must be removed from the equipment due to the lack of a convenient disassembly structure. This undoubtedly increases the workload and cost of maintenance, especially in some complex electronic equipment systems, where this maintenance inconvenience is even more prominent. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-5 As shown, this utility model provides an easy-to-disassemble and maintain connector, mainly comprising a housing 1 and a conductive terminal module 2 disposed within the housing 1. The housing 1 is composed of an interlocking upper cover 11 and a base 12, and this split structure provides a basis for subsequent disassembly and maintenance.

[0030] The upper cover 11 is provided with several guide ribs 111 extending along the insertion direction. These guide ribs 111 have trapezoidal cross-sections and are staggered with the locking rods 112. The trapezoidal cross-section guide ribs 111 play a good guiding role during the installation of the connector, ensuring accurate mating between the upper cover 11 and the base 12. At the same time, several elastic locking rods 112 are provided on the upper cover 11, and the ends of the locking rods 112 are provided with locking bosses 113. The elastic locking rods 112 can deform during installation, making it easy to insert into the corresponding structure of the base 12, while the locking bosses 113 are the key components for realizing the locking function.

[0031] The base 12 is provided with a guide groove 121 that mates with the guide rib 111. When the top cover 11 is installed, the guide rib 111 is inserted into the guide groove 121. Under the action of the trapezoidal cross section, it can effectively guide the movement direction of the top cover 11, ensuring the accuracy of installation. The base 12 is also provided with a sliding groove 122 for the locking rod 112 to slide. The sliding groove 122 is connected to the inner wall of the base 12, which allows the locking rod 112 to slide smoothly in the sliding groove 122. The end of the sliding groove 122 is provided with a locking hole 123 that penetrates the side of the base 12. When the locking rod 112 slides to the end of the sliding groove 122, the locking boss 113 will engage with the locking hole 123, thereby forming a detachable structure and realizing a firm connection between the top cover 11 and the base 12.

[0032] In addition, the side of the base 12 is provided with several patches 126 that connect to the corresponding locking bosses 113. The patches 126 are embedded and installed on the outside of the base 12, and their end faces are provided with plug-in portions 127 for insertion and fixing inside the locking bosses 113. The patch 126 further enhances the connection stability between the locking bosses 113 and the base 12, and improves the overall structural strength of the connector.

[0033] When the conductive terminal module 2 is installed inside the housing 1, the bottom surface of the base 12 has several terminal mounting holes 124. The conductive terminal module 2 is bidirectionally fixed by a lower retaining groove 125 on the base 12 and an upper retaining groove 114 on the upper cover 11. Specifically, the top of the conductive terminal module 2 has an upper protrusion 203 that matches the upper retaining groove 114. The upper protrusion 203 is engaged in the upper retaining groove 114, thus achieving upper fixation. The bottom of the conductive terminal module 2 has a lower protrusion 204 that matches the lower retaining groove 125. The lower protrusion 204 is engaged in the lower retaining groove 125, thus achieving lower fixation. This bidirectional fixation method can effectively prevent the conductive terminal module 2 from shifting within the housing 1, ensuring its stable operation.

[0034] The conductive terminal module 2 is provided with at least two contact terminals 201 for connecting to electricity. Each contact terminal 201 extends through a corresponding terminal mounting hole 124 to the bottom of the base 12. Each contact terminal 201 is fixed to the base 12 by a snap-fit ​​portion 202 located on the outer side, which extends through the terminal mounting hole 124 and is an arc-shaped surface extending in the insertion direction. The arc-shaped snap-fit ​​portion 202, when passing through the terminal mounting hole 124, forms a good fit with the hole wall, facilitating installation and ensuring a secure connection between the contact terminal 201 and the base 12, preventing loosening.

[0035] To ensure the connector's heat dissipation performance during operation, the upper surface of the top cover 11 is provided with several upper heat dissipation holes 115 that communicate with the inner wall, and the lower surface of the base 12 is provided with several lower heat dissipation holes 128 that communicate with the inner wall. When the conductive terminal module 2 operates, it generates heat, which can be dissipated through the upper heat dissipation holes 115 and the lower heat dissipation holes 128, thereby effectively reducing the internal temperature of the connector and extending its service life.

[0036] Specifically, during installation, the conductive terminal module 2 is placed on the base 12, with the lower protrusion 204 of the conductive terminal module 2 aligned with the lower slot 125 of the base 12. The lower protrusion 204 is then snapped into the lower slot 125, achieving initial fixation of the lower part of the conductive terminal module 2. The contact terminal 201 is then passed through the corresponding terminal mounting hole 124. Because the snap-fit ​​part 202 is an arc surface, it contacts the hole wall and undergoes a certain elastic deformation when passing through the terminal mounting hole 124. After successfully passing through the hole, the snap-fit ​​part 202 returns to its original shape, thereby fixing the contact terminal 201 to the base 12. The guide rib 111 of the upper cover 11 is aligned with the guide groove 121 of the base 12, and then the upper cover 11 is slowly pushed along the insertion direction. During the pushing process, the guide rib 111 slides in the guide groove 121, playing a guiding role and ensuring accurate movement of the upper cover 11. As the top cover 11 is pushed, the locking rod 112 is gradually inserted into the insertion slide 122. Due to the elasticity of the locking rod 112, it undergoes a certain deformation during insertion. When the locking rod 112 slides to the end of the insertion slide 122, the locking boss 113 aligns with the locking hole 123. At this time, the elasticity of the locking rod 112 is restored, and the locking boss 113 is engaged in the locking hole 123, realizing the locking connection between the top cover 11 and the base 12. At the same time, the upper protrusion 203 of the conductive terminal module 2 is engaged in the upper slot 114 of the top cover 11, completing the bidirectional limiting and fixing of the conductive terminal module 2. Finally, the insertion part 127 of the patch 126 is inserted into the locking boss 113 to further fix the locking boss 113 and enhance the overall structural stability of the connector.

[0037] Specifically, during disassembly, firstly, remove the patch 126 from the outside of the base 12, separating the insertion part 127 from the locking boss 113. Then, apply a certain external force to the locking rod 112, causing it to elastically deform away from the locking hole 123, thereby moving the locking boss 113 out of the locking hole 123. Next, push the upper cover 11 in the opposite direction of insertion, causing the guide rib 111 to slide out of the guide groove 121, separating the upper cover 11 from the base 12. After the upper cover 11 is removed, the conductive terminal module 2 can be inspected and maintained. To remove the conductive terminal module 2, simply lift it upwards, causing the lower protrusion 204 to disengage from the lower slot 125, and simultaneously the upper protrusion 203 to disengage from the upper slot 114, allowing the conductive terminal module 2 to be removed. For maintenance of the contact terminal 201, an external force can be applied to the locking part 202 with appropriate tools to deform the locking part 202, thereby removing the contact terminal 201 from the terminal mounting hole 124 for inspection or replacement.

[0038] Compared with traditional technologies, the connector provided by this technical solution, through the split structure of the upper cover 11 and the base 12, and the combination of the guide rib 111 and the guide groove 121, the locking rod 112 and the locking hole 123, and the sliding and fixed structure of the snap-fit ​​part 202 on the contact terminal 201, realizes the easy disassembly connection of the housing 1, which facilitates the overall disassembly and maintenance of the connector, and can greatly improve maintenance efficiency and reduce maintenance costs.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
