Description

Technical Field

[0001] This utility model relates to the field of radio frequency connector technology, specifically to an SMP connector that is easy to assemble and disassemble. Background Technology

[0002] SMP connectors are widely used in high-density electronic devices due to their small size and wide frequency range. However, most existing SMP connectors use either a "threaded engagement lock" or a "fixed snap-lock" structure, which presents the following problems: 1. Low assembly and disassembly efficiency: The threaded engagement structure requires 3-5 rotations to lock or unlock. In equipment with a dense layout of multiple connectors, the operation is time-consuming and prone to interference with adjacent components. 2. Tool-dependent operation: Some snap-fit ​​structures require tools such as tweezers and flathead screwdrivers to press and unlock, making quick disassembly and assembly impossible without tools; 3. Poor connection reliability: It is easy to loosen after use, or the threads may strip due to wear, affecting the stability of signal transmission.

[0003] To address the aforementioned issues, a tool-free, one-step assembly / disassembly, and reliable locking SMP connector structure needs to be designed. Utility Model Content

[0004] The purpose of this invention is to provide an SMP connector that is easy to install and disassemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an SMP connector that is easy to assemble and disassemble, comprising a socket assembly and a plug assembly that cooperate with each other. The socket assembly and the plug assembly achieve quick locking and unlocking through an elastic locking mechanism. The socket assembly includes a socket shell and a socket inner conductor. The socket shell is cylindrical, with symmetrically arranged axially extending guide protrusions on the center of its inner wall. The outer end of the socket shell has a locking protrusion. The socket inner conductor is embedded in the center of the socket shell. A spring is sleeved on the outer side of the socket inner conductor. One end of the spring is fixedly connected to the bottom of the inner cavity of the socket shell, and the other end is fixedly connected to a movable top block, which is sleeved on the socket inner conductor. The plug assembly includes a plug shell, a tapered guide head, and a plug inner conductor. The plug housing has a positioning cavity that mates with the socket housing.

[0014] 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.

[0015] Please see Figure 1-6 This utility model provides a technical solution: an SMP connector that is easy to assemble and disassemble, including a socket assembly 1 and a plug assembly 2 that cooperate with each other. The socket assembly 1 and the plug assembly 2 are quickly locked and unlocked by an elastic locking mechanism.

[0016] The socket assembly 1 includes a socket housing 11 and a socket inner conductor 12. The socket housing 11 is cylindrical, and the inner wall is symmetrically provided with axially extending guide protrusions 15. The outer end of the socket housing 11 is provided with a locking protrusion 16. The socket inner conductor 12 is embedded in the center of the socket housing 11. A spring 14 is sleeved on the outer side of the socket inner conductor 12. One end of the spring 14 is fixedly connected to the bottom of the inner cavity of the socket housing 11, and the other end is fixedly connected to a movable top block 13. The movable top block 13 is sleeved on the socket inner conductor 12.

[0017] Furthermore, the end of the guide protrusion 15 is an arc-shaped structure, which facilitates the docking of the guide protrusion 15 with the guide groove 27 and improves the insertion efficiency. The length of the guide protrusion 15 is less than the inner cavity depth of the socket housing 11, so that the docking of the guide protrusion 15 and the guide groove 27 is carried out inside the socket housing 11, ensuring stable docking between the two.

[0018] Furthermore, the locking protrusion 16 is integrated into the outer end of the socket housing 11, and the locking protrusion 16 has a circular structure with a minimum inner diameter equal to the inner diameter of the socket housing 11, making the outer end of the socket housing 11 arc-shaped. This facilitates the insertion of the tapered guide head 25 into the socket housing 11 and also facilitates the connection of the socket housing 11 to the plug housing 21, thereby improving the insertion efficiency.

[0019] Furthermore, the movable top block 13 forms a movable structure inside the socket housing 11 through the spring 14, and the outer side of the movable top block 13 abuts against the outer end face of the tapered guide head 25, which can hold the tapered guide head 25, increase the stability of the connection state of the tapered guide head 25, and also provide convenience when pulling out and disassembling.

[0020] The plug assembly 2 includes a plug housing 21, a tapered guide head 25, and a plug inner conductor 26. The plug housing 21 has a positioning cavity that mates with the socket housing 11. The tapered guide head 25 is fixed at the center of the plug inner conductor 26, and the outer end of the tapered guide head 25 is inserted into the socket housing 11. The center of the tapered guide head 25 is fixed with the plug inner conductor 26. The socket inner conductor 12 is inserted into the plug inner conductor 26. The outer side of the tapered guide head 25 has a guide groove 27 along the axial direction, and the guide groove 27 is adapted to the guide protrusion 15.

[0021] The plug housing 21 is provided with an elastic locking mechanism. The elastic locking mechanism includes a locking connection part 22, a second spring 23, and a movable locking block 24. The locking connection part 22 is fixedly connected to the plug housing 21. The locking connection part 22 is provided with a second spring 23 and a movable locking block 24. The movable locking block 24 forms a movable telescopic structure in the locking connection part 22 through the second spring 23. The outer side of the movable locking block 24 contacts the locking protrusion 16.

[0022] Furthermore, the movable locking block 24 is spherical in shape and protrudes from the inner wall of the plug housing 21. The inner diameter of the plug housing 21 is equal to the maximum outer diameter of the locking protrusion 16, ensuring normal insertion and removal limiting operation and improving disassembly and assembly efficiency.

[0023] Furthermore, the outer end of the tapered guide head 25 protrudes beyond the outer side of the plug housing 21, allowing the tapered guide head 25 to first engage with the socket housing 11, ensuring a stable and normal docking process between the socket housing 11 and the plug housing 21.

[0024] Specifically, when using this easy-to-install SMP connector, first align the tapered guide head 25 with the outer opening of the socket housing 11. Due to the tapered shape of the outer end of the tapered guide head 25 and the locking protrusion 16 on the outer end of the socket housing 11, the tapered guide head 25 can be easily inserted into the socket housing 11. When the tapered guide head 25 is inserted into the socket housing 11, it maintains a stable docking state. By rotating the plug assembly 2, the guide groove 27 on the tapered guide head 25 can quickly dock with the locking protrusion 16 inside the socket housing 11, thereby achieving complete insertion of the tapered guide head 25 and the socket housing 11. After the tapered guide head 25 is fully inserted into the socket housing 11, the outer end of the socket housing 11 will be inserted into the plug housing 21. The locking protrusion 16 will press the movable locking block 24 inside the plug housing 21 and pass through the plug housing 21. At this time, the movable locking block 24 will limit the locking protrusion 16 under the action of the second spring 23, so that the socket housing 11 and the plug housing 21 maintain a stable plugging state. The tapered guide head 25 is connected to the movable top block 13 inside the socket housing 11. The movable top block 13 is pressed outward by the first spring 14 and, together with the limiting of the locking protrusion 16, can ensure a stable plugging state between the socket assembly 1 and the plug assembly 2. The plugging and installation of the SMP connector is thus completed. When disassembly is required, the plug assembly 2 can be pulled directly, and the locking protrusion 16 will press the movable locking block 24 to exit from the plug housing 21, thus completing the disassembly work directly.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
