Description

Technical Field

[0001] The present invention belongs to the technical field of SMP connectors, and particularly relates to a self-locking SMP coaxial connector and a manufacturing method thereof. Background Art

[0002] An SMP connector is a radio frequency coaxial connector for high-frequency signal transmission, belonging to the type of miniature and high-performance connectors. Currently, standard SMP connectors are divided into three types of plugging and unplugging forces: optical hole, semi-escape, and full-escape, which are respectively applied to different scenarios. When the plug is mated with the cable, a flange fixation or other pressing block structure is usually used to apply an external force to ensure reliable contact in an environment where the cable swings or vibrates. However, the flange or other pressing block structures are complex to operate and occupy a large space, which does not conform to the current development trend of miniaturization and high efficiency.

[0003] Therefore, we provide a self-locking SMP coaxial connector and a manufacturing method thereof to solve the above problems. Summary of the Invention

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0005] The present invention is a self-locking SMP coaxial connector and a manufacturing method thereof, including:

[0006] An SMP-K type plug and an SMP-J type socket;

[0007] A locking mechanism composed of a front sleeve and a locking contact head is arranged outside the SMP-K type plug, wherein the front sleeve is fixed to the outer shell of the SMP-K type plug;

[0008] A card slot matching with the locking mechanism is arranged on the outer shell of the SMP-J type socket;

[0009] The locking mechanism can achieve self-locking by pushing the locking contact head into the card slot through the front sleeve after the SMP connector is engaged, and the locking contact head can be disengaged from the card slot by pulling the front sleeve backward during separation.

[0010] The present invention is further configured such that the front-end shell of the SMP-K type plug is a cavity structure, a connection end is arranged in the cavity, and a spring is arranged between the connection end and its shell.

[0011] The present invention is further configured such that the locking contact head is provided with a barb at its front end, and the barb is adapted to the card slot of the SMP-J type socket to form a mechanical lock.

[0012] The present invention is further configured such that a jack is provided at the middle position of the front connection end of the SMP-K type plug, and the jack is adapted to the connection head provided in the middle of the SMP-J type socket, and the protrusion at the end of the connection end cooperates with the annular groove at the bottom of the SMP-J type socket.

[0013] The present invention is further configured such that an insulator is embedded in the connection end at the front end of the SMP-K type plug, and the insulator is arranged around the jack.

[0014] The present invention is further configured such that the front end of the front sleeve is sleeved outside the SMP-J type socket, and the locking contact head is fixed inside the front sleeve;

[0015] When the SMP connector needs to be separated, by pulling the front sleeve backward, the locking contact head can be contracted and disengaged from the card slot, and the SMP connector is compatible with the standard SMP-K type connector.

[0016] A manufacturing method of a self-locking SMP coaxial connector includes the following steps:

[0017] Assemble a locking mechanism composed of a front sleeve and a locking contact head outside the SMP-K type plug;

[0018] Machine a card slot on the SMP-J type socket housing that matches the locking mechanism;

[0019] The above steps need to ensure that the locking mechanism can achieve self-locking by pushing the locking contact head into the card slot through the front sleeve after the connector is engaged.

[0020] The present invention is further configured such that the locking contact head is subjected to a specific aging treatment to make it have sufficient elasticity to maintain good performance during insertion and extraction.

[0021] The present invention is further configured such that after manufacturing, the function of the locking mechanism is tested to ensure that when the front sleeve is pulled backward, the locking contact head can smoothly disengage from the card slot, and at the same time, it can stably maintain the self-locking state under normal operating conditions

[0022] The present invention has the following beneficial effects:

[0023] 1. By adding a locking mechanism including a front sleeve and a locking contact head with barbs outside the SMP-K type plug, the present invention can be automatically locked in the card slot on the SMP-J type socket after insertion, significantly enhancing the stability of the connector under adverse conditions such as vibration and pulling, effectively reducing the risk of accidental disconnection. The barb at the front end of the locking contact head has been subjected to aging treatment, with excellent elasticity and durability, ensuring reliable mechanical locking can still be maintained during multiple plugging and unplugging operations.

[0024] 2. The locking mechanism of the SMP connector proposed by the present invention simplifies the operation process. Users only need to perform simple pushing and pulling actions to complete the locking and unlocking processes of the connector, without the need to use additional tools or complex steps, which simplifies the on-site installation and maintenance work processes, improves work efficiency. When the locking contact head fully enters the card slot to achieve locking, users can intuitively feel the state change of the connector, increasing the confidence in operation.

[0025] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] Embodiment

[0034] Please refer to Figures 1-3 , the present invention is a self-locking SMP coaxial connector and its manufacturing method, including:

[0035] SMP-K type plug 100 and SMP-J type socket 200;

[0036] The outside of the SMP-K type plug 100 is provided with a locking mechanism composed 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;

[0037] The outer shell of the SMP-J type socket 200 is provided with a card slot that matches the locking mechanism;

[0038] After the SMP connector is engaged, the locking mechanism can push the locking contact head 102 into the card slot through the front sleeve 101 to achieve self-locking, and when separating, the locking contact head 102 can be disengaged from the card slot by pulling the front sleeve 101 backward. The SMP-K type plug 100 and the SMP-J type socket 200 are self-locked through the locking mechanism, which is convenient for locking and unlocking the SMP connector, and at the same time ensures the accuracy and reliability of the operation.

[0039] Specifically, a jack 105 is opened at the middle position of the front connection end 103 of the SMP-K type plug 100, and the jack 105 is adapted to the connection head 201 provided in the middle of the SMP-J type socket 200. An insulator 106 is embedded in the front connection end 103 of the SMP-K type plug 100, and the insulator 106 is arranged around the jack 105. The end of the connection end 103 protrudes and is adapted to the annular groove at the bottom of the SMP-J type socket 200. The locking contact head 102 is provided with a barb at its front end, and the barb is adapted to the card slot of the SMP-J type socket 200 to form a mechanical lock;

[0040] The barbs at the front end of the locking contact head 102 have been aged treated, with good elasticity and durability. When inserted into the SMP-J type socket 200, the barbs can extend into the card slots to form a mechanical lock, preventing accidental disconnection. When separating, pulling the front sleeve 101 backward can cause the barbs to contract and disengage from the card slots; the connection end 103 is provided with a jack 105 for docking with the connector 201 in the SMP-J type socket 200. In addition, the protrusion at the end of the connection end 103 cooperates with the annular groove at the bottom of the SMP-J type socket 200, increasing the connection stability, enhancing the stability of the electrical connection and physical fixation, and reducing the risk of loosening caused by vibration or pulling; the insulator 106 is arranged around the jack 105, ensuring electrical isolation, avoiding current leakage, improving safety, and protecting the device from electrical faults; the card slots of the SMP-J type socket 200 are precisely machined to be adapted to the barbs on the locking contact head 102. This card slot not only provides a position for mechanical locking but also improves the connection safety and reliability through its appropriate size and shape, ensuring the effectiveness of the self-locking mechanism, making the connection between the SMP-K type plug 100 and the SMP-J type socket 200 both firm and easy to separate subsequently.

[0041] Further, the front-end housing of the SMP-K type plug 100 is a cavity structure, and a connection end 103 is arranged in its cavity, and a spring 104 is arranged between the connection end 103 and its housing;

[0042] The spring 104 is placed between the connection end 103 and its housing to achieve buffering protection for the connection end 103, avoiding loosening of the connection end 103 during the plugging and unplugging process of the SMP-K type plug 100. At the same time, the reaction force exerted by the spring 104 on the front sleeve 101 through the housing of the SMP-K type plug 100 can further improve the stability of the locking mechanism.

[0043] This SMP connector is compatible with standard SMP-K type connectors.

[0044] The implementation principle of this embodiment is as follows:

[0045] 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 to move forward, causing the barbs to enter the card slots to form a mechanical lock, and the jack 105 is precisely docked with the connector 201 to achieve electrical connection. The protrusion at the end of the connection end 103 cooperates with the annular groove at the bottom of the socket to enhance physical fixation.

[0046] When the SMP-K type plug 100 is separated from the SMP-J type socket 200, pull the front sleeve 101 backward. The front sleeve 101 exerts a reverse force on the locking contact head 102, causing its barbs to contract and disengage from the card slots, and this SMP connector can be easily separated without using additional tools or complex operation steps.

[0047] A manufacturing method of a self-locking SMP coaxial connector, comprising the following steps:

[0048] Before assembling the outer sleeve 101 and the locking contact head 102 to form a locking mechanism on the outside of the SMP-K type plug 100, perform a specific aging treatment on the locking contact head 102 to make it have sufficient elasticity so as to maintain good performance during the insertion and extraction processes;

[0049] Machine a card slot on the housing of the SMP-J type socket 200 that matches the locking mechanism;

[0050] The above steps need to ensure that the locking mechanism can achieve self-locking by pushing the locking contact head 102 into the card slot through the outer sleeve 101 after the connector is engaged. After manufacturing, test the function of the locking mechanism to ensure that when the outer sleeve 101 is pulled backward, the locking contact head 102 can smoothly disengage from the card slot, and at the same time can stably maintain the self-locking state under normal operating conditions.

[0051] In summary, this self-locking SMP coaxial connector not only solves the problems of complex fixation and large space occupation existing in traditional connectors, but also improves the connection reliability, simplifies the operation process, enhances the device compatibility, and improves the user experience through an optimized self-locking structure.
