[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0022] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0023] Example 1

[0024] Reference Figure 1 to Figure 4 The present embodiment provides a π-type DB9 connector that is easy to assemble, including a plug connector 100 on which a positioning ring plate 200 is disposed.

[0025] The positioning ring plate 200 is used to position the plug connector 100 so that the plug connector 100 is aligned with the plug hole 301 on the socket 300 .

[0026] Specifically, a conductive socket is provided at the end of the plug connector 100, and a conductive layer is provided on the inner wall of the socket to be connected to a conversion mainboard provided inside the plug connector 100. The conversion mainboard is used for signal processing, etc. How it is electrically connected and its working principle are prior arts and will not be repeated here. The present application improves the housing hardware of the plug connector 100 to avoid the problem of bending the PIN pin in the socket 301 during the insertion of the plug connector 100 into the socket 301. The reason for this problem is that the prior art uses bolts to connect the plug connector 100 and the socket 301, so the depth of the socket 301 is shallow, so there is a problem of crooked insertion of the plug connector 100 when inserted into the socket 301.

[0027] Furthermore, a embedding groove 101 is provided on the side of the plug connector 100 , and an embedding block 201 is provided on the inner side of the positioning ring plate 200 , and the embedding block 201 is arranged in the embedding groove 101 .

[0028] The insert block 201 can move in the insert groove 101 , so the positioning ring plate 200 can slide on the plug connector 100 .

[0029] A sleeve plate 202 is disposed at one end of the positioning ring plate 200 , and a first groove 203 is disposed inside the positioning ring plate 200 ; the positioning ring plate 200 also includes a socket 300 , a socket 301 is disposed on the socket 300 , and a peripheral edge 302 is disposed at the opening of the socket 301 .

[0030] The jack 301 is provided with a PIN pin to realize electrical connection with the plug connector 100 . The connection between the PIN pin and the circuit inside the socket 300 is a prior art and will not be described in detail.

[0031] The outer side of the sleeve plate 202 matches the inner side of the surrounding edge 302 in size.

[0032] A closing groove 102 is arranged on the side of the plug connector 100 , a buckle ball 103 is arranged in the closing groove 102 , and a spring 104 is arranged in the closing groove 102 to connect the buckle ball 103 .

[0033] The spike ball 103 partially extends out of the closing groove 102 , and squeezing the spike ball 103 can press the spike ball 103 back into the closing groove 102 , while the spike ball 103 will not separate from the closing groove 102 .

[0034] A second groove 303 is disposed on the side wall of the plug hole 301 ; an end plate 105 is disposed at the end of the plug connector 100 .

[0035] Therefore, in the utility model, in the initial state, the positioning ring plate 200 is at the end of the plug connector 100, and the buckle ball 103 is partially embedded in the first groove 203 to form a fixation. During the connection process, the sleeve plate 202 is first sleeved on the outside of the surrounding edge 302, and then the plug connector 100 is pressed hard to complete the connection. During this process, the buckle ball 103 is disengaged from the first groove 203 and then connected to the second groove 303 to complete the plug-in process.

[0036] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
