Description

Technical Field

[0001] This utility model belongs to the field of SMP connector technology, and in particular relates to a self-locking SMP coaxial connector. Background Technology

[0002] SMP connectors are radio frequency coaxial connectors used for high-frequency signal transmission, belonging to the miniature, high-performance connector type. Currently, standard SMP connectors come in three mating forces: optical aperture, semi-escapement, and full escapement, each applied to different scenarios. When mating cables, flange fixing or other clamping structures are typically used to apply external force to ensure reliable contact under cable swaying or vibration. However, flange or other clamping structures are complex to operate and occupy a large space, which does not conform to the current trend of miniaturization and high efficiency.

[0003] To address these issues, we provide a self-locking SMP coaxial connector. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

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.

[0027] Example

[0028] Please see Figure 1-3 This utility model is a self-locking SMP coaxial connector, comprising:

[0029] SMP-K type plug 100 and SMP-J type socket 200;

[0030] The SMP-K type plug 100 is provided with a locking mechanism consisting of a front sleeve 101 and a locking contact head 102, wherein the front sleeve 101 is fixed to the outer shell of the SMP-K type plug 100.

[0031] The SMP-J type socket 200 housing is provided with a slot that cooperates with the locking mechanism;

[0032] The locking mechanism can achieve self-locking by pushing the locking contact head 102 into the slot through the front sleeve 101 after the SMP connector is engaged. When disengaging, the locking contact head 102 is disengaged from the slot by pulling the front sleeve 101 backward. The SMP-K type plug 100 and SMP-J type socket 200 are self-locked by the locking mechanism, which facilitates locking and unlocking of the SMP connector, while ensuring the accuracy and reliability of operation.

[0033] Specifically, the SMP-K type plug 100 has a socket 105 in the middle of the front end 103, which is adapted to the connector 201 in the middle of the SMP-J type socket 200. The front end 103 of the SMP-K type plug 100 has an insulator 106 embedded in it, which surrounds the socket 105. The end protrusion of the connector 103 cooperates with the annular groove at the bottom of the SMP-J type socket 200. The locking contact head 102 has a barb at its front end, which is adapted to the slot of the SMP-J type socket 200 to form a mechanical lock.

[0034] The barb at the front end of the locking contact 102 has undergone aging treatment, providing excellent elasticity and durability. When inserted into the SMP-J type socket 200, the barb extends into the slot to form a mechanical lock, preventing accidental disconnection. Upon separation, pulling the front sleeve 101 backward retracts the barb and disengages it from the slot. The connecting end 103 is provided with a socket 105 for mating with the connecting head 201 in the SMP-J type socket 200. Furthermore, the protrusion at the end of the connecting end 103 engages with the annular groove at the bottom of the SMP-J type socket 200, increasing the stability of the connection and enhancing the stability and physical integrity of the electrical connection. The fixed design reduces the risk of loosening due to vibration or pulling; the insulator 106 is arranged around the socket 105 to ensure electrical isolation, prevent current leakage, improve safety, and protect the equipment from electrical faults; the slot of the SMP-J type socket 200 is precisely machined to fit the barb on the locking contact head 102. This slot not only provides a mechanical locking position, but also improves the safety and reliability of the connection through its appropriate size and shape, ensuring the effectiveness of the self-locking mechanism, so that the connection between the SMP-K type plug 100 and the SMP-J type socket 200 is both firm and easy to separate later.

[0035] Furthermore, the front end housing of the SMP-K type plug 100 has a cavity structure, and a connection end 103 is provided inside the cavity. A spring 104 is provided between the connection end 103 and the housing.

[0036] The spring 104 is placed between the connecting end 103 and its housing to provide buffer protection for the connecting end 103 and prevent the connecting end 103 from loosening during the insertion and removal of the SMP-K type plug 100. At the same time, the reaction force applied by the spring 104 to the front sleeve 101 through the housing of the SMP-K type plug 100 can further improve the stability of the locking mechanism.

[0037] This SMP connector is compatible with the standard SMP-K type connector.

[0038] The implementation principle of this embodiment is as follows:

[0039] When the SMP-K type plug 100 is inserted into the SMP-J type socket 200, the front sleeve 101 pushes the locking contact head 102 forward, so that the barb enters the slot to form a mechanical lock. The socket 105 and the connector 201 are precisely aligned to achieve electrical connection. The protrusion at the end of the connector 103 cooperates with the annular groove at the bottom of the socket to enhance physical fixation.

[0040] When the SMP-K type plug 100 is separated from the SMP-J type socket 200, the front sleeve 101 is pulled back. The front sleeve 101 applies a reverse force to the locking contact head 102, causing its barb to retract and disengage from the slot. The SMP connector can then be easily separated without the use of additional tools or complicated operating procedures.

[0041] In summary, this self-locking SMP coaxial connector not only solves the problems of complex fixing and large space occupation of traditional connectors, but also improves the reliability of the connection, simplifies the operation process, enhances equipment compatibility, and improves the user experience through its optimized self-locking structure.
