The top of the boss structure has an insertion interface, and the bottom of the housing has a through hole that communicates with the receiving cavity. A plug-in assembly is installed in the receiving cavity for allowing a wire to enter through the through hole and connect to the plug-in assembly; A self-locking assembly includes a locking plate, a linkage assembly, and an unlocking latch. The locking plate is located on the side of the plug-in assembly facing the plug-in interface and is inclined relative to the plug-in assembly. The locking plate has a through hole corresponding to the plug-in interface. The linkage assembly connects the locking plate and the unlocking latch. The unlocking latch is located on the outside of the housing. A fixing component is disposed within a receiving cavity. The fixing component includes at least two positioning parts and at least one wire clamping member. The two positioning parts are disposed on the inner wall of the housing, and there is a positioning space between the two positioning parts. The wire clamping member is installed on the positioning parts to restrict the wire in the positioning space.
[0007] In one embodiment, the outer shell includes a front shell and a bottom shell. The front shell is detachably installed on the bottom shell. The front shell and the bottom shell form a receiving cavity. The top of the bottom shell is provided with an insertion interface. The bottom of the bottom shell and / or the bottom of the front shell are provided with through holes that communicate with the receiving cavity. The bottom shell and the top shell together define the abutment portion, and the top of the boss structure is located on the bottom shell.
[0008] In one embodiment, a limiting block is provided at the bottom of the bottom shell protruding towards the unlocking buckle, the unlocking buckle is provided with an avoidance groove, and the limiting block abuts against the side wall of the avoidance groove to limit the unlocking buckle.
[0009] In one embodiment, the linkage component includes a connecting part and a linkage part, the connecting part connecting the linkage part to the unlocking buckle, and the linkage part connecting the locking plate.
[0010] In one embodiment, the linkage includes a bent portion, an extension portion, and a snap-fit portion. The bent portion is bent relative to the connecting portion, the extension portion extends along the length direction of the locking piece, and the snap-fit portion snaps into the side of the locking piece.
[0011] In one embodiment, the snap-fit portion is provided with a second inclined surface, which is disposed corresponding to the first inclined surface; Correspondingly, the locking plate is provided with a third inclined surface, which is provided in relation to the second inclined surface.
[0012] In one embodiment, the self-locking assembly further includes a reset member connected to the linkage part, the reset member being used to reset the linkage part and the locking plate.

[0016] The technical solution of this utility model is equipped with a self-locking component. When the electrical plug is inserted into the connector, the self-locking component fixes the position of the electrical plug relative to the connector, thereby improving the stability of the connection between the connector and the electrical plug. Specifically, when the plug part of the electrical plug is inserted into the socket, the locking plate will rotate under the action of the plug until the through hole and the socket are aligned. At this time, the electrical plug can be inserted smoothly. After the electrical plug is inserted, the operator can operate the unlocking buckle to drive the locking plate to move, thereby tilting the through hole and the socket, thus restricting the movement of the electrical plug from the socket. When unlocking is required, the unlocking buckle is pulled outward to align the through hole with the socket to unlock. Furthermore, in the technical solution of this utility model, the contact surface is used to provide contact and limit the insulating shell of the power plug. Compared with the traditional connector structure without the first inclined surface, the setting of the first inclined surface of the boss structure reduces the material on the one hand, and on the other hand, enables the connector to be adapted to electrical plugs that are compatible with the shape of the boss structure, as well as electrical plugs with a rectangular outline without the first inclined surface, thereby improving the versatility of the connector.

[0024] Connectors are common equipment in building electrical installations, used to connect electrical equipment to power sources, and are an important component of power supply systems in homes, offices, and industrial sites.
[0025] Existing connectors typically consist of a plug and a socket. In actual operation, it is easy for the plug to become loose or even be pulled out of the socket due to external factors, which can cause great inconvenience to people working normally and may even lead to safety hazards in serious cases.
[0026] Therefore, there is an urgent need for a connector to strengthen the connection with electrical equipment in order to avoid the above situation from occurring.
[0027] This utility model proposes a connector 100 to improve the stability of the connection between the connector 100 and electrical equipment.
[0028] Please see Figures 1 to 5 In one embodiment of this utility model, the connector 100 includes a housing 1, a plugging assembly 2, a self-locking assembly 3, and a fixing assembly 4. The housing 1 has a receiving cavity and includes an abutment portion 11 and a boss structure 12. The abutment portion 11 includes an abutment surface 111. The boss structure 12 is disposed on the abutment surface 111 and protrudes outward. The side of the boss structure 12 has multiple first inclined surfaces 121, which connect two adjacent sides of the boss structure 12, such that the orthographic projection of the boss structure 12 in the direction perpendicular to the abutment surface 111 is completely inside the contour of the abutment surface 111, and the projected contour of the boss structure 12 is a partially missing rectangle. The top of the boss structure 12 has a plug-in interface 122, and the bottom of the housing 1 has a through hole 13 communicating with the receiving cavity. The plugging assembly... 2 is installed in the receiving cavity to allow the wire to enter through the through hole 13 and connect to the plug-in assembly 2; the self-locking assembly 3 includes a locking plate 31, a linkage assembly 32, and an unlocking buckle 33. The locking plate 31 is located on the side of the plug-in assembly 2 facing the plug-in interface 122 and is inclined relative to the plug-in assembly 2. The locking plate 31 is provided with a through hole 311, which corresponds to the plug-in interface 122. The linkage assembly 32 connects the locking plate 31 and the unlocking buckle 33. The unlocking buckle 33 is located on the outside of the housing 1; the fixing assembly 4 is located in the receiving cavity. The fixing assembly 4 includes at least two positioning parts 41 and at least one wire clamping member 42. The two positioning parts 41 are located on the inner wall of the housing 1, and there is a positioning space between the two positioning parts 41. The wire clamping member 42 is installed on the positioning parts 41 to restrict the wire in the positioning space.
[0029] The technical solution of this utility model is provided with a self-locking component 3. When the electrical plug is inserted into the connector 100, the self-locking component 3 fixes the position of the electrical plug relative to the connector 100, thereby improving the stability of the connection between the connector 100 and the electrical plug. Specifically, when the plug of the electrical plug is inserted into the plug interface 122, the locking piece 31 will rotate under the drive of the plug until the through hole 311 is aligned with the plug interface 122. At this time, the electrical plug can be inserted smoothly. After the electrical plug is inserted, the unlocking buckle 33 can be operated by the operator to drive the locking piece 31 to move, thereby tilting the through hole 311 and the plug interface 122. This restricts the movement of the electrical plug out of the plug interface 122. When unlocking is required, the unlocking buckle 33 is pulled outward to align the through hole 311 with the plug interface 122 to unlock. Furthermore, in the technical solution of this utility model, the contact surface 111 is used to provide contact and limit the insulating shell 1 of the power plug. The setting of the first inclined surface 121 of the boss structure 12, compared with the traditional connector 100 structure without the first inclined surface 121, reduces the material on the one hand, and on the other hand, makes the connector 100 adaptable to both electrical plugs with the shape of the boss structure 12 and electrical plugs with a rectangular outline without the first inclined surface 121, thereby improving the versatility of the connector 100.
[0030] Please see Figure 3 To facilitate regular maintenance and replacement of the internal components of the connector 100, in this embodiment of the invention, the outer shell 1 includes a front shell 14 and a bottom shell 15. The front shell 14 is detachably mounted on the bottom shell 15, and the front shell 14 and the bottom shell 15 form a receiving cavity. The top of the bottom shell 15 is provided with a plug interface 122, and the bottom of the bottom shell 15 and / or the bottom of the front shell 14 are provided with a through hole 13, which communicates with the receiving cavity. The bottom shell 15 and the front shell 14 together define the abutment portion 11, and the top of the boss structure 12 is located on the bottom shell 15. By making the outer shell 1 a detachable front shell 14 and bottom shell 15, it is convenient to regularly maintain and replace the internal components of the connector 100. Furthermore, placing the top of the boss structure 12 on the bottom shell 15 avoids separating the plug interface 122, reducing processing difficulty and ensuring stable connection with the electrical plug.
[0031] To guide and limit the unlocking buckle 33, in this embodiment of the invention, a limiting block 151 protrudes from the bottom of the bottom shell 15 toward the unlocking buckle 33. The unlocking buckle 33 has a relief groove 331, and the limiting block 151 abuts against the side wall of the relief groove 331 to limit the unlocking buckle 33. When the locking plate 31 needs to be unlocked, the unlocking buckle 33 needs to be pulled outward, so that the linkage component 32 and the locking plate 31 move in the same direction, ultimately making the through hole 311 of the locking plate 31 aligned with the plug interface 122. This allows the electrical plug to be pulled out of the connector 100. During this process, the limiting block 151 prevents the unlocking buckle 33 from shifting during pulling or resetting, thereby avoiding the positional shift of the linkage component 32 and the locking plate 31, which could lead to the electrical plug being unable to be inserted into the connector 100 due to the positional shift of the locking plate 31.
[0032] Please see Figure 4 and Figure 5 Since the unlocking buckle 33 is located outside the outer casing 1 and is some distance from the locking plate 31, in order to drive the movement of the locking plate 31 through the unlocking buckle 33, in this embodiment of the invention, the linkage component 32 includes a connecting part 321 and a linkage part 322. The connecting part 321 connects the linkage part 322 to the unlocking buckle 33, and the linkage part 322 connects to the locking plate 31. In other words, through the linkage component 32, the movement of the unlocking buckle 33 can drive the movement of the locking plate 31.
[0033] Furthermore, in a further embodiment of this utility model, the linkage part 322 includes a bending part 3221, an extension part 3222, and a snap-fit part 3223. The bending part 3221 is bent relative to the connecting part 321. The extension part 3222 extends along the length direction of the locking piece 31. The snap-fit part 3223 snaps into the side of the locking piece 31. The bending part 3221 is provided because the locking piece 31 is located in the middle of the boss structure 12. In order to facilitate the utilization of the internal space of the connector 100, the connecting part 321 is located on the inner side of the outer shell 1, which is slightly outward. Therefore, the bending part 3221 is needed to compensate for this positional deviation. The extension part 3222 is provided to facilitate the adjustment of the positional error between the connecting part 321 and the locking piece 31. The snap-fit part 3223 is used to snap into the locking piece 31.
[0034] In an embodiment of this utility model, the snap-fit portion 3223 is provided with a second inclined surface 32231, which corresponds to the first inclined surface 121; correspondingly, the locking piece 31 is provided with a third inclined surface 312, which corresponds to the second inclined surface 32231. That is, the snap-fit portion 3223 is provided with a second inclined surface 32231, corresponding to the first inclined surface 121 on the boss structure 12. This facilitates the assembly of the snap-fit portion 3223 and the outer shell 1, and reduces the material required for the snap-fit portion 3223. Furthermore, the third inclined surface 312 on the locking piece 31 corresponds to the second inclined surface 32231 on the snap-fit portion 3223, which facilitates assembly, provides a specific installation position, and also reduces material usage.
[0035] To enable the locking plate 31 to automatically reset after unlocking, in this embodiment of the invention, the self-locking component 3 further includes a reset member (not shown). The reset member is connected to the linkage part 322 and is used to reset the linkage part 322 and the locking plate 31. It should be noted that this invention does not limit the installation position or specific form of the reset member, as long as it ensures that the locking plate 31 automatically resets after unlocking. Specifically, in this embodiment of the invention, the reset member includes a spring and is installed on the linkage part 322. The spring's restoring force resets the linkage part 322, further resetting the locking plate 31.
[0036] In an embodiment of this utility model, the plug-in assembly 2 is installed on the bottom shell 15, one end of the reset member is elastically connected to the linkage part 322, and the other end is elastically connected to the plug-in assembly 2. That is, by placing the reset member between the plug-in assembly 2 and the linkage part 322, the locking piece 31 can automatically reset after unlocking, and the internal layout of the connector 100 is more reasonable.
[0037] Please see Figure 4 To guide the movement of the connecting part 321 and prevent it from shifting, in this embodiment of the invention, the plug-in assembly 2 is provided with a guide channel protruding towards the unlocking buckle 33. The guide channel is located between the two positioning parts 41. One end of the connecting part 321 passes through the through hole 13 and the guide channel and is connected to the linkage part 322. The guide channel limits the movement of the connecting part 321, preventing it from shifting.
[0038] Please see Figure 3It should be noted that this utility model does not limit the connection and fixing method of the front shell 14 and the bottom shell 15. In the embodiment of this utility model, the front shell 14 is provided with a locking foot 141 on the side near the limiting block 151, and the locking foot 141 is locked into the limiting block 151. The front shell 14 is provided with a blocking block 142 on the side near the insertion interface 122. The bottom shell 15 is provided with a baffle 152 corresponding to the blocking block 142, and the blocking block 142 is locked into the baffle 152, so that the front shell 14 and the bottom shell 15 are locked together. By providing limiting structures at both ends of the front shell 14 to cooperate with the bottom shell 15, the fixing stability of the front shell 14 and the bottom shell 15 is good.
[0039] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
