[0026] 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.

[0027] 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 is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1 to Figure 3 , which is the first embodiment of the utility model, and this embodiment provides a plug connector, including a plug unit 100, including, a plug base 101 on which a plurality of terminal connectors 102 are fixedly arranged, and the terminal connectors 102 penetrate the front and rear ends of the plug base 101;

[0030] The wire take-up unit 200 includes a connector housing 201 , which is disposed at the front end of the plug-in base 101 . A wire sleeve 202 is also connected to the side of the connector housing 201 , and the two are connected via a snap-fit ​​assembly 203 .

[0031] Furthermore, connection grooves 101a are provided on the upper and lower sides of the plug base 101. The connection grooves 101a penetrate the upper and lower ends of the plug base 101 and are rectangular grooves. They are connected with the connector housing 201 to protect the safety of the plug base 101 and the wires. A positioning slope 101b is also provided on one side of the plug base 101 to determine the direction when plugging in the connector to avoid damage to the equipment and injuries to personnel due to incorrect plugging.

[0032] Furthermore, positioning posts 101c are extended from the four corners of the rear end of the plug base 101 for contacting the socket for positioning during plugging. A plurality of terminal sockets 101d are also vertically arranged on the rear side of the plug base 101 to cooperate with the terminal connector 102 .

[0033] Furthermore, a plurality of baffles 101d - 1 are extended from both sides of the terminal socket 101d , and the terminal connectors 102 are respectively arranged between the baffles 101d - 1 for isolating the plurality of terminal connectors 102 .

[0034] Furthermore, the front end of the terminal connector 102 is a wiring terminal 102a, which extends out from the front side of the plug-in base 101, and the rear end of the terminal connector 102 is a plug-in terminal 102b, which extends out from the rear side of the plug-in base 101 and cooperates with the terminal plug-in socket 101d.

[0035] Furthermore, the wiring terminal 102a is a diamond-shaped single-hole connector, and the shorter diagonal of its opening is parallel to the surface of the plug-in base 101. The length of the plug-in end 102b is consistent with the length of the terminal socket 101d, and there is a five-degree angle between its direction and the terminal socket 101d. The end of the plug-in end 102b is a clamping section 102b-1, which is oriented close to the terminal socket 101d, and the distance between its end and the terminal socket 101d is the thickness of the terminal piece of the fixed interface of the equipment.

[0036] When in use, the wire is connected and fixed to the terminal 102a as needed, and the terminal 102a can be squeezed to clamp the wire through its opening to ensure a more stable connection. Then the plug-in base 101 is connected to the device in the direction of the positioning slope 101b. During the terminal connection process, the plug-in terminal 102b cooperates with the clamping section 102b-1 to clamp and connect the fixed interface terminal, making the terminal connection more stable and not easy to loosen.

[0037] In summary, by providing the positioning column 101c and the design of the terminal connector 102, it is possible to ensure a stable connection of the connector and to ensure that it is not easy to loosen after multiple plugging and unplugging.

[0038] Example 2

[0039] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model. Based on the previous embodiment, this embodiment further provides a plug connector. The difference between this embodiment and the first embodiment is that:

[0040] Furthermore, the two ends of the connecting piece housing 201 and the plug-in base 101 are provided with clamping feet 201a, the ends of which are triangular inclined blocks protruding inwards, which are used to connect the plug-in base 101, and the clamping feet 201a cooperate with the connecting grooves 101a.

[0041] Furthermore, a wire hole 201b is provided at the upper end of the connector housing 201, which cooperates with the wire sleeve 202. A docking hole 201c and an adjustment hole 201d are symmetrically provided on both sides of the wire hole 201b. The width of the adjustment hole 201d is greater than twice the width of the docking hole 201c.

[0042] Furthermore, snap-fit ​​plates 202a extend symmetrically on both sides of the end of the wire sleeve 202, which cooperate with the docking hole 201c and are used to connect and fix the wire sleeve 202 to the connector housing 201. The snap-fit ​​plate 202a is also provided with a snap-fit ​​hole 202b, which cooperates with the snap-fit ​​assembly 203.

[0043] Furthermore, the locking assembly 203 includes a locking member 203a slidably arranged on the inner side of the connector housing 201 and a locking spring 203b connected to the rear end of the locking member 203a. The locking member 203a cooperates with the locking hole 202b, and its front end is a sloped locking block 203a-1, and an opening and closing plate 203a-2 is arranged on the upper side. The opening and closing plate 203a-2 is arranged in the adjustment hole 201d. When in the locking state, under the action of the elastic force of the locking spring 203b, the sloped locking block 203a-1 cooperates with the locking hole 202b to fix the wire sleeve 202.

[0044] When in use, after connecting the wires to the terminal connector 102, all the wires are gathered and tied together and then placed into the wire sleeve 202 through the wire hole 201b for storage. The connector housing 201 is connected and fixed to the plug base 101, and the clamping plate 202a of the wire sleeve 202 is clamped with the docking hole 201c. The front end of the wire sleeve pushes the inclined clamping block 203a-1 to shrink it, and then enters the clamping hole 202 under the elastic force of the clamping spring 203b. b, the connection is completed. When the wire needs to be adjusted and the wire sleeve 202 needs to be opened, the opening and closing plates 203a-2 are pushed to both sides to disengage the inclined clamping block 203a-1 from the locking hole 202b, thereby releasing the limit on the wire sleeve 202 and completing the disassembly work. After loosening the opening and closing plates 203a-2, under the action of the elastic force of the locking spring 203b, the inclined clamping block 203a-1 returns to the position of the docking hole 201c again, so as to facilitate re-engagement.

[0045] In summary, the wire sleeve 202 is snap-connected by the snap-fit ​​assembly 203, which is convenient for assembly and disassembly and for the management of the wires.
