Description

Technical Field

[0001] The utility model relates to the technical field of connector pins, in particular to an eccentric connector pin structure. Background Art

[0002] Connectors are essential components for electrical connections in entire circuit systems. As electronic products become increasingly lightweight and thinner, connectors are being driven toward smaller size, lower height, narrower pitch, and greater functionality. The M5 connector is the smallest of the commonly used circular connectors. Its greatest advantage is its minimal footprint, making it suitable for space-constrained circuit systems.

[0003] According to an eccentric connector pin structure disclosed in Chinese patent CN202223270670.4, this application eccentrically arranges the central axis of the pin part and the central axis of the solder cup part. In the connector housing, while keeping the position coordinates of the four pin parts unchanged, it effectively increases the distance between the center points of the connecting grooves at one end of the four solder cup parts, which can meet the requirements of welding and fixing the 24AWG wire harness with the solder cup part, effectively expanding the diameter of the connecting groove, and facilitating the wiring harness with larger wire diameter to be inserted into the connecting groove and then welded and fixed with the solder cup part. The existing connector pin structure protects the through hole by clamping the elastic sealing sleeve on the limit ring. When the welding is not firm, the elastic sealing sleeve needs to be removed and re-welded through the through hole. Since the elastic sealing sleeve is clamped on the limit ring by the T-shaped clamp, it is more troublesome to disassemble.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0005] In view of the problems in the related art, the present invention proposes an eccentric connector pin structure to overcome the above technical problems existing in the existing related art.

[0006] To this end, the specific technical solutions adopted in this utility model are as follows:

[0007] An eccentric connector pin structure includes a connector shell, a plurality of evenly distributed mounting grooves are provided in the connector shell, a pin portion is provided in the mounting groove, a solder cup portion is provided on one side of the pin portion and extends to the outside of the connector shell, a mounting sleeve is provided on the outer wall of the connector shell, a welding hole connected to the solder cup portion is provided on the outer wall of the mounting sleeve, a sealing sleeve is provided on the outer wall of the mounting sleeve, and the sealing sleeve is connected to the mounting sleeve through a connecting assembly.

[0008] Preferably, the mounting sleeve is fixedly connected to the connector housing.

[0009] Preferably, the outer wall of the sealing sleeve is provided with a plurality of evenly distributed anti-slip grooves. Preferably, the connecting assembly includes a plurality of evenly distributed guide blocks provided on the outer wall of the mounting sleeve, a sliding groove provided on the inner wall of the sealing sleeve to match the guide blocks, a travel groove provided in the guide block, a matching slider provided in the travel groove, a return spring provided at the bottom end of the slider, a stop ball provided on the side of the slider away from the return spring that extends outside the guide block, and a stop groove provided on the sealing sleeve to match the stop ball.

[0010] Preferably, the guide block is fixedly connected to the mounting sleeve, and the sliding block is connected to the guide block via the return spring.

[0023] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] According to an embodiment of the present utility model, an eccentric connector pin structure is provided. Example

[0025] like Figure 1-7 As shown, the eccentric connector pin structure according to the embodiment of the present invention includes a connector housing 1, characterized in that a plurality of evenly distributed mounting grooves 2 are provided in the connector housing 1, a pin portion 3 is provided in the mounting groove 2, a solder cup portion 14 extending to the outside of the connector housing 1 is provided on one side of the pin portion 3, a mounting sleeve 4 is provided on the outer wall of the connector housing 1, a welding hole 5 connected to the solder cup portion 14 is provided on the outer wall of the mounting sleeve 4, a sealing sleeve 6 is provided on the outer wall of the mounting sleeve 4, and the sealing sleeve 6 is connected to the mounting sleeve 4 through a connecting assembly. Example

[0026] like Figure 1-7As shown, the connector housing 1 includes a plurality of evenly distributed mounting slots 2, each of which includes a pin portion 3. A solder cup portion 14 extending outside the connector housing 1 is provided on one side of the pin portion 3. A mounting sleeve 4 is provided on the outer wall of the connector housing 1. A solder hole 5 is provided on the outer wall of the mounting sleeve 4, which communicates with the solder cup portion 14. A sealing sleeve 6 is provided on the outer wall of the mounting sleeve 4, which is connected to the mounting sleeve 4 via a connecting assembly. The mounting sleeve 4 is fixedly connected to the connector housing 1. The outer wall of the sealing sleeve 6 includes a plurality of evenly distributed anti-slip grooves 7. The connection assembly includes several evenly spaced guide blocks 8 on the outer wall of the mounting sleeve 4. A sliding groove 9 is defined on the inner wall of the sealing sleeve 6, matching the guide blocks 8. A travel groove 10 is defined in the guide block 8, and a matching slider 11 is located within this travel groove 10. A return spring 12 is located at the bottom of the slider 11. A stop ball 13 is located on the side of the slider 11 that extends beyond the guide block 8, away from the return spring 12. A stop groove is defined in the sealing sleeve 6, matching the stop ball 13. The guide block 8 is fixedly connected to the mounting sleeve 4, and the slider 11 is connected to the guide block 8 via the return spring 12. The stop ball 13 is fixedly connected to the slider 11.

[0027] In actual application, when the wiring harness and the welding cup part 14 are not firmly welded and need to be re-welded, the personnel can pull the sealing sleeve 6 to one side, and the sealing sleeve 6 is squeezed by the force to squeeze the limiting ball 13. When the pulling force is too large, the reset spring 12 begins to compress, and the limiting ball 13 disengages from the limiting groove on the sealing sleeve 6 and enters the travel groove 10. At this time, the sealing sleeve 6 is released from the limit and slides off the mounting sleeve 4. Then the welding hole 5 on the mounting sleeve 4 that is connected to the welding cup part 14 is exposed, and the personnel can re-drip solder liquid into the welding hole 5. By setting up the connecting component, when the wiring harness is not firmly welded and falls off, the personnel can quickly slide the sealing sleeve to open the welding hole on the mounting sleeve and re-drip solder liquid for welding. The operation is more flexible and convenient, and the subsequent maintenance efficiency is improved.

[0028] To sum up, with the help of the above-mentioned technical solution of the present invention, by setting up a connecting component, when the wiring harness is not welded firmly and falls off, personnel can quickly slide the sealing sleeve, open the welding hole on the mounting sleeve, and re-drip solder liquid for welding. The operation is more flexible and convenient, and the efficiency of subsequent maintenance is improved.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
