Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to an electrical connector with quick unlocking and plugging. Background Art

[0002] For the existing electrical connector with a self-locking structure, generally, a spring piece and a buckle are formed on the side surface of the connector, and the connection strength between the two ends of the electrical connector is enhanced by the insertion of the buckle and the spring piece to achieve self-locking.

[0003] However, for this self-locking method, the locking strength is low. After being subjected to pressure, the spring piece is prone to break, thus affecting the connection strength between the two ends of the electrical connector. Therefore, in order to ensure the locking after the connection of the connector, this electrical connector with quick unlocking and plugging is designed. Content of the Utility Model

[0004] The purpose of the utility model is to provide an electrical connector with quick unlocking and plugging, which realizes the locking of the male plug and the female plug by rotating the lock catch to move the limiting groove onto the positioning shaft, enhances the connection stability between the male plug and the female plug, and avoids the two from slipping off.

[0005] The utility model provides the following technical solution: an electrical connector with quick unlocking and plugging, including a male plug and a female plug that are inserted into each other. An installation shaft is formed on the outer surface of the female plug, and a lock catch is also sleeved on the installation shaft. The lock catch locks the male plug and the female plug. Installation holes are opened at both ends of the lock catch, and the installation holes cooperate with the installation shaft. A limiting groove is opened on the inner wall of the lock catch. A positioning shaft is formed on the surface of the male plug. When locked, the positioning shaft is inserted into the limiting groove. A groove is opened on the inner wall of the lock catch. A limiting platform is also formed on the male plug. When the lock catch rotates and locks, the limiting platform is buckled into the groove.

[0006] In order to prevent the two ends of the lock catch from slipping off, a baffle is formed at the end of the installation shaft, and the baffle extends to the outside of the installation shaft. A convex platform is formed on the inner wall at one end of the installation hole. During installation, the installation shaft is inserted into the installation hole, and the baffle extends from between the convex platforms to the outside of the convex platforms. When the lock catch is locked, the lock catch drives the convex platform to rotate, and the baffle is located on the outer end surface of the convex platform to limit the two ends of the lock catch.

[0007] In order to guide the insertion of the male plug and the female plug, the female plug includes a female plug ring plate and a female socket. A gap is formed between the female socket and the female plug ring plate. A male plug ring plate is formed on the surface of the male plug, and the male plug ring plate is inserted into the gap between the female socket and the female plug ring plate.

[0008] In order to prevent misoperation, the limiting platform and the groove are on the same side. A positioning groove is opened on the inner wall of the female plug ring plate, and a positioning strip is formed on the surface of the male plug ring plate. The positioning strip cooperates with the positioning groove.

[0009] To facilitate the rotation of the buckle, a handle is formed outward on the outer surface of the buckle, and the handle and the groove are on the same central axis.

[0010] To guide the locking of the limiting platform and reduce the deformation of the buckle, a chamfer is also formed on one end surface of the buckle, and the limiting platform is buckled into the groove through the chamfer.

[0011] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0012] (1) By providing a buckle, the limiting groove is moved to the positioning shaft by the rotation of the buckle to realize the locking of the male plug and the female plug, enhancing the connection stability between the male plug and the female plug and preventing the two from slipping off.

[0013] (2) By forming a groove on the inner wall of the buckle and a limiting platform on the male plug, and using the limiting platform to buckle into the groove, the locking strength of the buckle for the male plug and the female plug is enhanced, ensuring the connection stability between the male plug and the female plug.

[0014] (3) By using the baffle formed on the installation shaft, through the locking of the buckle, the baffle is located outside the boss, and then by rotating the buckle, the male plug and the female plug are locked. At the same time, the baffle rotates to be located on the outer surface of the boss, locking both ends of the buckle to prevent both ends of the buckle from slipping outward.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. Embodiment

[0024] Please refer to Figures 1 to 3 , the present invention provides a technical solution: a quick-unlocking pluggable electrical connector, including a male plug 2 and a female plug 1 that are inserted into each other. A mounting shaft 12 is formed on the outer surface of the female plug 1, and a lock 3 is also sleeved on the mounting shaft 12. The lock 3 locks the male plug 2 and the female plug 1. Mounting holes 32 are opened at both ends of the lock 3, and the mounting holes 32 cooperate with the mounting shaft 12. A limiting groove 31 is opened on the inner wall of the lock 3. A positioning shaft 21 is formed on the surface of the male plug 2. When the lock 3 is locked, the lock 3 rotates, and the limiting groove 31 is rotated to the outside of the positioning shaft 21. At the same time, the limiting groove 31 limits the axial direction of the positioning shaft 21, locking the male plug 2 and the female plug 1. A groove 34 is opened on the inner wall of the lock 3, and a limiting platform 24 is also formed on the male plug 2. When the lock 3 rotates and locks, the limiting platform 24 is buckled into the groove 34. By the blocking of the limiting platform 24 on the groove 34, the locking strength between the male plug 2 and the female plug 1 is further enhanced, ensuring the stable connection between the male plug 2 and the female plug 1.

[0025] As Figure 3 、 4 and shown in 5, a baffle 13 is formed at the end of the mounting shaft 12, and both ends of the baffle 13 extend to the outside of the mounting shaft 12. A boss 33 is formed on the inner wall of one end of the mounting hole 32, and the bosses 33 are symmetrically arranged on the inner wall of the mounting hole 32. During installation, the mounting shaft 12 is inserted into the mounting hole 32, and the baffle 13 extends from between the bosses 33 to the outside of the bosses 33. When the lock 3 is locked, the lock 3 rotates, and the bosses 33 also rotate, so that the baffle 13 is located on the outer end surface of the bosses 33, limiting both ends of the lock 3 to prevent the two ends of the locked lock 3 from slipping off the mounting shaft 12 under pressure.

[0026] As Figure 1As shown in the figure, the female plug 1 includes a female plug ring plate 11 and a female socket 14. A gap is formed between the female socket 14 and the female plug ring plate 11. A male plug ring plate 22 is formed on the surface of the male plug 2. The male plug ring plate 22 is inserted into the gap between the female socket 14 and the female plug ring plate 11. Through the insertion of the male plug ring plate 22 and the gap, the insertion of the male plug 2 and the female plug 1 is guided.

[0027] As Figure 1 and 6 shown in the figure, a positioning groove 15 is formed on the inner wall of the female plug ring plate 11, and a positioning strip 23 is formed on the surface of the male plug ring plate 22. The positioning strip 23 cooperates with the positioning groove 15. By using the cooperation of the positioning strip 23 and the positioning groove 15, the insertion of the male plug 2 and the female plug 1 is positioned, so that the limiting platform 24 and the groove 34 are on the same side, improving the insertion accuracy of the male plug 2 and the female plug 1.

[0028] As Figure 2 shown in the figure, a handle 35 is formed outward on the outer surface of the lock 3. The setting of the handle 35 makes it more convenient for the lock 3 to receive force, further making the lock 3 rotate more quickly. The handle 35 and the groove 34 are on the same central axis, and the groove 34 is located below the handle 35, so that the groove 34 also receives force, further facilitating the buckling of the groove 34 on the limiting platform 24.

[0029] A chamfer 36 is also formed on one end surface of the lock 3. The limiting platform 24 is buckled into the groove 34 through the chamfer 36. The chamfer 36 plays a guiding role, making the locking of the lock 3 smoother and also reducing the deformation of the lock 3.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
