[0026] 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 efforts shall fall within the protection scope of the present invention.
[0027] As Figures 1-4 shown, the present invention discloses an electrical connector convenient for maintenance, including a plug connector 1, a mounting base 2, and a plug-in body 3 located between the mounting base 2 and the plug connector 1. A circuit board 4 (this is the prior art and the wiring connection method is well-known, and only a schematic diagram is shown in the figure) is provided on the mounting base 2 and is matched with the rear side of the plug-in body 3. A wire insertion hole 11 is provided on the plug connector 1. A sealing ring 5 is also included. One side of the plug-in body 3 is located inside the plug connector 1 and the other end is located inside the mounting base 2. The mounting base 2 and the plug connector 1 are detachably connected by bolts, buckles, etc. The sealing ring 5 is located between the plug connector 1 and the mounting base 2. 1. Since the mounting base 2 and the plug connector 1 are detachably connected, when it is necessary to maintain and repair the electrical connector, after separating the mounting base 2 and the plug connector 1 at this time, it is possible to detect and repair the damaged parts of the local parts, thereby extending the service life of the entire electrical connector; 2. Since the sealing ring 5 is located between the plug connector 1 and the mounting base 2, for the separable plug connector 1 and the mounting base 2, there is a sealing ring 5 at the connection position between the two, which can reduce the entry of external moisture from the connection position between the two, thereby improving the waterproof performance of the electrical connector.
[0028] Among them, a locking member 6 is further included. The plug connector 1 includes a mating section 12 at the front side. An external thread 121 is provided on the outer periphery of the mating section 12. The locking member 6 is in threaded cooperation with the external thread 121. After objects such as cables and wires are inserted into the wire insertion hole 11, the locking member 6 is rotated at this time to be located in the circumferential direction of the mating section 12, which can provide a more secure connection and reduce the occurrence of situations such as the cable loosening or falling off due to external vibrations, acting forces, etc.
[0029] Among them, a plurality of contact grooves 61 are circumferentially spaced on the locking member 6. The arrangement of each contact groove 61 can increase the frictional force in the circumferential direction of the locking member 6, facilitate manually tightening or loosening the locking member 6, and improve the operation convenience.
[0030] Preferably, the front side diameter of the plug body 3 is smaller than that of the rear side, and it is set in a frustum shape. An installation groove 13 with the same shape and size as the plug body 3 is provided in the plug connector 1. The plug body 3 includes a connection disk 31 at the rear side. The plug connector 1 protrudes backward with a plurality of bumps 17. The connection disk 31 is provided with installation grooves 311 corresponding to each bump 17. 1. Since the front side diameter of the plug body is smaller than the rear side diameter, and the installation groove 13 in the plug connector 1 is adapted to the shape of the plug connector 1, during the process of inserting the plug body into the installation groove 13, only the front side of the plug body can be aligned with the rear side of the installation groove 13 and inserted. Because the rear side diameter of the plug body is larger than the front side diameter of the installation groove 13, the rear side of the plug body cannot be inserted from the front side of the installation groove 13, which limits the insertion direction of the plug body. At the same time, after the installation is completed, the rear side of the plug body 3 cannot enter the front side of the installation groove 13 forward, which not only ensures the accuracy during the assembly process but also enhances the structural stability after the final assembly. Furthermore, it makes it convenient for the plug body inserted into the installation groove 13 not to move axially forward to fix it with the plug connector 1; 2. At the same time, when the plug body 3 is inserted, at this time, the installation grooves 311 of the connection disk 31 cooperate with the bumps 17 at the rear side of the plug connector 1, so that the two cannot rotate relative to each other, which facilitates the assembly and fixation of the plug body and the plug connector 1.
[0031] Among them, a plurality of jacks 312 are provided on the connection disk 31. The front side of the connection disk 31 abuts against the rear side end face of the plug connector 1, and the plug connector 1 is provided with screw holes 14 corresponding to each jack 312. After a bolt with a model adapted to the screw hole 14 is inserted into the jack 312 and then threaded with the screw hole 14, the connection disk 31 can be fixed to the plug connector 1, and thus the plug body 3 can be fixed to the plug connector 1, so that the plug body 3 cannot move or shake relative to the plug connector 1, and it can be stably located in the installation groove 13.
[0032] Among them, a limiting ring 15 is integrally formed on the outer periphery of the plug connector 1, and the limiting ring 15 includes an insertion section 151 for inserting the mounting seat 2, and the sealing ring 5 is located between the insertion section 151 and the mounting seat 2. The plug connector 1 is located on the rear side of the limiting ring 15 and is protruding with a number of positioning blocks 16, and the mounting seat 2 includes a sleeve 21 made of rubber on the front side, and the sleeve 21 is provided with a positioning slot 211 corresponding to each positioning block 16. In the process of moving the mounting seat 2 forward and onto the plug connector 1, the front end face of the mounting seat 2 will abut against the limiting ring 15 of the plug connector 1, thereby completing the axial position determination of the two.
[0033] Preferably, each of the positioning blocks 16 is in a stepped configuration with the width of the outer end face being smaller than the width of the inner end face. By radially bending the sleeve 21 outward, each positioning block 16 can be made to enter the corresponding positioning slot 211. At the same time, the stepped configuration with a narrow outer side and a wide inner side helps to align with the corresponding positioning slot 211 more easily, thereby facilitating the alignment of the positioning block 16 with the positioning slot 211. At the same time, due to the presence of each positioning block 16, the mounting base 2 after assembly cannot be radially rotated or axially moved compared to the plug connector 1, thereby ensuring the safety and reliability of the connection between the two.
[0034] The mounting base 2 further includes a mounting plate 22 located at the rear side of the sleeve 21 , and mounting holes 221 are provided on both the left and right sides of the mounting plate 22 . The arrangement of the mounting plate 22 and the mounting holes 221 can facilitate the fixed installation of the electrical connector.
[0035] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
