Description

Technical Field

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

[0002] An RF connector is an electronic component used for high-frequency signal transmission. It is usually attached to a cable or installed on an instrument as a component for electrically connecting or disconnecting transmission lines. Its main function is to connect or disconnect two RF ports when needed, so as to realize the electrical connection, disconnection or conversion of different types of transmission lines.

[0003] In practical applications, the existing RF connectors have relatively complete structures and functions, which can meet basic usage requirements, but the following problems still exist:

[0004] When the male and female connectors of an RF connector are connected, they are mainly fixed by friction. When the RF connector is subjected to a large external force (such as pulling force or tripping), the male and female connectors may separate, thus affecting its normal use.

[0005] Therefore, this utility model provides a self-locking radio frequency connector. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a self-locking radio frequency connector.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a self-locking radio frequency connector, comprising a female connector and a male connector, wherein the female connector and the male connector are inserted together; a self-locking insertion structure is provided between the female connector and the male connector, the self-locking insertion structure comprising a mounting block, the outer surface of the mounting block being fixedly connected to the outer surface of the female connector, a sliding rod being inserted into the inner wall of the mounting block and the female connector, and a circular stop block being fixedly connected to the top end of the sliding rod; a guide fixing structure is provided between the female connector and the male connector, the guide fixing structure comprising an operating ring plate, the inner wall of the operating ring plate being fixedly connected to the outer surface of the male connector, and a plurality of first rectangular protrusions being fixedly connected to the outer surface of the operating ring plate.

[0008] In a preferred embodiment, a return spring is sleeved on the outer surface of the sliding rod, and the two ends of the return spring are fixedly connected to the round stop block and the mounting block, respectively. A snap-fit ​​connector is fixedly connected to the bottom end of the sliding rod, and a snap-fit ​​hole is opened on the outer surface of the male connector. The snap-fit ​​hole snaps into the snap-fit ​​connector, and a chamfer plate is fixedly connected to one side of the male connector.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the return spring, it can cooperate with the sliding rod to make the snap-fit ​​connector snap-fit ​​and fix it with the snap-fit ​​hole. In this way, after the male connector and the female connector are snap-fit ​​and fixed, they can be self-locking and fixed, thereby avoiding the separation of the male connector and the female connector due to external pulling force.

[0010] In a preferred embodiment, the inner wall of the female connector is provided with a circular insertion hole, and a circular insertion rod is fixedly connected to one side of the male connector.

[0011] The technical effect of adopting the above-mentioned further solution is that the round plug can be inserted into the inner wall of the round plug hole, so that the female connector and the male connector can be locked in a fixed position during the locking process, and the locking connector can be aligned with the locking hole without manual alignment.

[0012] In a preferred embodiment, an annular plate is fixedly connected to one side of the outer surface of the female connector, a plug-in cylinder is fixedly connected to one side of the outer surface of the annular plate, a plug-in rod is fixedly connected to one side of the outer surface of the operating ring plate, and a second rectangular protrusion is fixedly connected to the outer surface of the plug-in rod.

[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the plug-in tube and the plug-in rod, the male connector and the female connector can be assisted in being aligned and snapped together, thereby facilitating the snapping and alignment of the female connector and the male connector.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting a self-locking insertion structure, under the action of the round insertion rod and the round insertion hole, the male connector and the female connector can be aligned on the same horizontal line during the insertion and fixing process. Under the action of the return spring, the snap-fit ​​connector can be assisted in resetting, allowing it to snap into the inner wall of the snap-fit ​​hole, thus completing the snap-fit ​​fixing of the male and female connectors. By setting a guide fixing structure, under the action of the insertion rod, it can assist in the insertion and fixing with the insertion cylinder, thereby assisting in the fixing of the annular plate, and thus assisting in the fixing and alignment of the male and female connectors during insertion.

[0024] 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.

[0025] like Figures 1-4As shown, this embodiment provides a technical solution: a self-locking radio frequency connector, including a female connector 1 and a male connector 2, which are inserted into each other; a self-locking insertion structure 3 is provided between the female connector 1 and the male connector 2, the self-locking insertion structure 3 includes a mounting block 31, the outer surface of the mounting block 31 is fixedly connected to the outer surface of the female connector 1, a sliding rod 32 is inserted into the inner wall of the mounting block 31 and the female connector 1, and a round stop block 33 is fixedly connected to the top of the sliding rod 32; a guide fixing structure 4 is provided between the female connector 1 and the male connector 2, the guide fixing structure 4 includes an operating ring plate 41, the inner wall of the operating ring plate 41 is fixedly connected to the outer surface of the male connector 2, and a plurality of first... A rectangular protrusion 42, through the setting of a self-locking insertion structure 3, can, under the action of the round insertion rod 38 and the round insertion hole 36, ensure that the male connector 2 and the female connector 1 are fixed during the insertion process, so that the snap-fit ​​connector 35 can be on the same horizontal line as the snap-fit ​​hole 39. Under the action of the return spring 34, the snap-fit ​​connector 35 can be assisted in resetting, so that the snap-fit ​​connector 35 can be snapped into the inner wall of the snap-fit ​​hole 39, thereby completing the snap-fit ​​fixing of the male connector 2 and the female connector 1. Through the setting of a guide fixing structure 4, under the action of the insertion rod 43, it can assist in the insertion fixing with the insertion cylinder 46, thereby assisting in the fixing of the annular plate 45, and thus assisting in the fixing and alignment of the male connector 2 and the female connector 1.

[0026] Going a step further, such as Figures 2-3 As shown: A return spring 34 is sleeved on the outer surface of the sliding rod 32. The two ends of the return spring 34 are fixedly connected to the round stop block 33 and the mounting block 31, respectively. A snap-fit ​​connector 35 is fixedly connected to the bottom end of the sliding rod 32. A snap-fit ​​hole 39 is opened on the outer surface of the male connector 2. The snap-fit ​​hole 39 snaps with the snap-fit ​​connector 35. A chamfer plate 37 is fixedly connected to one side of the male connector 2. Under the action of the return spring 34, it can cooperate with the sliding rod 32 so that the snap-fit ​​connector 35 can snap and fix with the snap-fit ​​hole 39. After the male connector 2 and the female connector 1 are snapped and fixed, they can be self-locked and fixed, thereby preventing the male connector 2 and the female connector 1 from being separated by external pulling force.

[0027] The above solution also has the problem that during the insertion and fixing of the female connector 1 and the male connector 2, the positions need to be constantly adjusted to ensure that the snap-fit ​​connector 35 and the snap-fit ​​hole 39 are on the same horizontal line. Figure 2 and Figure 4 As shown: In this solution, the inner wall of the female connector 1 is provided with a circular insertion hole 36, and a circular insertion rod 38 is fixedly connected to one side of the male connector 2. The circular insertion rod 38 can be inserted into the inner wall of the circular insertion hole 36, so that the female connector 1 and the male connector 2 can be engaged in a fixed position during the engagement process, so that the engagement connector 35 can be aligned with the engagement hole 39 without manual alignment.

[0028] The above solutions still have the problem that the positions of the round plug 38 and the round plug hole 36 need to be aligned during insertion. However, during insertion, the plug may still shift due to external forces, resulting in inaccurate insertion angles. Figures 2-4 As shown, an annular plate 45 is fixedly connected to one side of the outer surface of the female connector 1, and a plug-in cylinder 46 is fixedly connected to one side of the outer surface of the annular plate 45. A plug-in rod 43 is fixedly connected to one side of the outer surface of the operating ring plate 41, and a second rectangular protrusion 44 is fixedly connected to the outer surface of the plug-in rod 43. Under the action of the plug-in cylinder 46 and the plug-in rod 43, the male connector 2 and the female connector 1 can be assisted in being aligned and snapped together, thereby facilitating the snapping and alignment of the female connector 1 and the male connector 2.

[0029] Working principle:

[0030] like Figure 1-4 As shown:

[0031] When in use: Align the plug rod 43 with the plug tube 46 so that the plug rod 43 can be snapped and fixed with the plug tube 46. At this time, the first rectangular protrusion 42 can prevent slipping, and the second rectangular protrusion 44 makes the plug rod 43 and the plug tube 46 more secure.

[0032] During the process of inserting the male connector 2 into the female connector 1, the round insert rod 38 can be inserted into the inner wall of the round insert hole 36. At the same time, when the snap connector 35 is aligned with the snap hole 39, the sliding rod 32 can drive the snap connector 35 to be inserted into the inner wall of the snap hole 39 under the reaction force of the return spring 34.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
