[0022] The pin-assembly connector of this utility model is described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1 As shown, the pin assembly connector provided in this embodiment of the present invention includes: a connector body 10 and pins 20. The connector body 10 can be an integrally formed structure or a detachable structure. The connector body 10 has a plurality of assembly holes 121 arranged in the axial direction. One end of each assembly hole 121 is provided with a constriction portion 122. The pins 20 are detachably inserted into the assembly holes 121. When it is necessary to connect cables, the pins 20 can be assembled in the corresponding assembly holes 121. After the pins 20 are inserted, a part of the pins 20 can be covered and locked by the constriction portion 122 so that the constriction portion 122 and the pins 20 interlock in the axial direction.

[0024] Reference Figures 2 to 4As shown, when the connector body 10 adopts a detachable structure, the connector body 10 includes: a housing 11 and an assembly body 12. The assembly body 12 is detachably disposed inside the housing 11 and is mutually locked with the housing 11 in the axial direction. The assembly hole 121 is provided on the assembly body 12. The assembly body 12 can be made of materials such as plastic or rubber, so that when the assembly body 12 is assembled with the housing 11, the assembly body 12 can undergo a certain deformation and be engaged in the housing 11.

[0025] Furthermore, the assembly body 12 has a first end face 123 and a second end face 124. The first end face 123 and the second end face 124 are opposite to each other in the axial direction of the assembly body 12, and the constricted portion 122 protrudes from the first end face 123. The first end face 123 can be an end face for plugging into electrical equipment, and the second end face 124 can be an end face for connecting to a cable. When the pin 20 is assembled into the assembly hole 121, the pin 20 can be inserted into the assembly hole 121 from the second end face 124 and protrude from the first end face 123, so that the part of the pin 20 protruding from the first end face 123 can be made conductive when plugged into the electrical equipment.

[0026] Specifically, the constricted portion 122 includes a connecting end 1221 and a deformable end. The connecting end 1221 is connected to the assembly body 12, and the deformable end is used to abut against the pin 20. The diameter of the constricted portion 122 gradually decreases from the connecting end 1221 to the deformable end. The deformable end has an opening groove 1222 that extends radially into the assembly hole 121. The opening groove 1222 divides the deformable end into a plurality of clamping pieces 1223. Each clamping piece 1223 can move closer to or separate from each other radially when subjected to force. Furthermore, it combines with... Figure 5 As shown, the pin 20 includes a plug section 21, an insert section 22, and a stop section 23 connected sequentially along the axial direction. The diameter of the plug section 21 is larger than the diameter of the insert section 22, and the diameter of the stop section 23 is larger than the diameter of the insert section 22. More preferably, the diameter of the plug section 21 is equal to the diameter of the insert section 22, and there is a locking section 24 between the plug section 21 and the insert section 22. The diameter of the locking section 24 is smaller than the diameter of the plug section 21. The constricted portion 122 covers the surface of the locking section 24 and abuts against the plug section 21.

[0027] In this embodiment, when the pin 20 is inserted into the assembly hole 121, when the insertion section 21 of the pin 20 enters the constricted portion 122, the insertion section 21 of the pin 20 can compress the various locking pieces 1223 at the deformable end to deform radially. After the insertion section 21 extends out of the constricted portion 122, since the diameter of the engaging section 24 is smaller than the diameter of the insertion section 21, the constricted portion 122 springs back under its own rigidity and fits into the engaging section 24, so that the constricted portion 122 abuts against the insertion section 21 in the engaging section 24, thereby forming an axial lock at the position of the insertion section 21. This makes the assembly of the pin 20 in the assembly hole 121 more consistent and more reliable.

[0028] Furthermore, a stop hole 1211 is provided at the end of the assembly hole 121 away from the constricted portion 122. The diameter of the stop hole 1211 is larger than the diameter of the assembly hole 121, and the stop section 23 is embedded in the stop hole 1211. This allows the stop section 23 and the stop hole 1211 to cooperate after the pin 20 is inserted into the assembly hole 121, preventing the pin 20 from moving toward the insertion section 21. At the same time, the pin 20 is prevented from moving toward the stop section 23 by the constricted portion 122. Thus, the pin 20 is axially locked in the assembly hole 121, preventing the pin 20 from loosening during the insertion process, and improving the overall assembly reliability.

[0029] As a preferred embodiment, both the first end face 123 and the second end face 124 are provided with a partition 125. The partition 125 separates each of the pins 20 in each assembly hole 121 from each other. When each pin 20 is assembled in each assembly hole 121, the partition 125 separates each pin 20, avoiding contact between each pin 20 and improving overall safety.

[0030] Reference Figure 3 and Figure 4 As shown, the assembly body 12 also includes an inner core layer 126 and a locking layer 127. The locking layer 127 is composed of several mutually separated locking parts, and each locking part is spaced around the inner core layer 126. At least one locking part has a protrusion 1271 on its outer side that abuts against the inner wall of the outer shell 11. When the assembly body 12 is installed in the outer shell 11, since the locking layer 127 and the inner core layer 126 are spaced apart and the locking layer 127 is composed of several mutually separated locking parts, the locking layer 127 can deform towards the inner core layer 126 when squeezed by the outer shell 11. By providing a groove 111 on the inner wall of the outer shell 11, after the locking layer 127 enters the outer shell 11, the protrusion 1271 on the outer side of the locking layer 127 can be engaged in the groove 111, so that the assembly body 12 and the outer shell 11 are locked in the axial direction, resulting in better overall consistency.

[0031] The pin 20 assembly connector provided by this utility model allows the pin 20 to be inserted into the assembly hole 121 when assembling with the connector body 10. This allows a portion of the pin 20 to be covered and engaged by the constriction portion 122, while the constriction portion 122 and the pin 20 can interlock in the axial direction. Thus, different numbers of pins 20 can be installed to meet diverse connection requirements when facing different cable connection needs. Furthermore, the assembly does not require tools; the pin 20 can be manually inserted directly into the assembly hole 121 to complete the assembly. The operation is simple and the assembly efficiency is higher.
