Description

Technical Field

[0001] This utility model relates to the field of power strip technology, specifically to a fixed track socket. Background Technology

[0002] CN220341625U discloses an embedded fixed track socket, in which the top cover assembly, protective door assembly, conductive component, support, and base are all mounted on the top surface of the upper housing. This causes the socket to protrude significantly from the fixed track socket, resulting in a large size that is easily damaged by impact. Moreover, the use of screw connections requires sequential alignment and connection of the top cover assembly, protective door assembly, conductive component, support, and base from the inside out of the upper housing, making the assembly process quite complex. Utility Model Content

[0003] The purpose of this invention is to provide a fixed track socket that is easy to assemble.

[0004] The purpose of this utility model is achieved as follows.

[0005] A fixed track socket includes a base assembly and a socket assembly. The base assembly has a receiving cavity and a non-circular mounting hole communicating with the receiving cavity. The socket assembly includes a base and a cover assembly. The outer circumference of the base is adapted to the mounting hole. The side of the base has an elastic latching protrusion. The base is inserted into the mounting hole. The cover assembly has a protruding edge. The bottom of the cover assembly extends into the mounting hole and is snapped into the base. The protruding edge and the elastic latching protrusion clamp the edge of the mounting hole.

[0006] This utility model utilizes the snap-fit ​​connection between the base and the cover assembly and clamps the edge of the mounting hole to achieve the assembly of the three components. The base can be placed in the receiving cavity and assembled with the cover assembly, or the base and the cover assembly can be assembled and then installed into the base assembly. Assembly can be completed without tools, making the operation simple and convenient. The assembly process can be flexibly adjusted according to the actual production situation. The base is located in the receiving cavity, and the socket assembly only protrudes from the cover assembly, making the socket assembly less prone to damage and reducing the overall size of the fixed track socket.

[0007] Furthermore, the face cover assembly includes a face cover body and a retaining ring. The outer diameter of the retaining ring is larger than the maximum diameter of the mounting hole, forming the raised edge. The bottom of the face cover body extends downward to form a vertically arranged insertion part. The insertion part has a locking hole. The corresponding base side has a vertically arranged slot. The slot has a protruding buckle. The insertion part is inserted into the slot, and the protruding buckle is engaged in the locking hole to form the buckle connection. The face cover body abuts against the top edge of the mounting hole through the retaining ring.

[0008] The retaining ring eliminates the error gap between the faceplate body and the base clamping base assembly.

[0009] Furthermore, the mounting hole has two opposite straight sections on its side, and the corresponding base has a planar sidewall. The planar sidewall has two parallel protrusions along the vertical direction, forming the slot between the two protrusions. At least one buckle is provided between the two protrusions, and the protrusions and buckles are located within the vertical projection range of the mounting hole.

[0010] The slot is easy to manufacture and does not affect the insertion of the base through the mounting hole.

[0011] Furthermore, the buckle is provided with a first guide slope to guide itself into the card hole, and the bottom of the insertion part is provided with a second guide slope to guide the buckle into the card hole.

[0012] The assembly of the buckle and the snap-fit ​​is effortless and easy.

[0013] Furthermore, an annular step is provided on the inner circumference of the fixing ring, and the cover body sits on the annular step.

[0014] The retaining ring restricts the circumferential displacement of the cover body, preventing the protruding buckle from disengaging from the locking hole.

[0015] Furthermore, the base is provided with an arc-shaped sidewall. The arc-shaped sidewall has two slots in the vertical direction from top to bottom. The arc-shaped sidewall between the two slots forms an elastic arm. An elastic latch extends from the top of the elastic arm, and the outer end of the latch extends beyond the vertical projection range of the mounting hole.

[0016] The elastic latch protrusion, through the elastic deformation of the elastic arm, facilitates the insertion of the base into the mounting hole.

[0017] Furthermore, the top of the elastic card protrusion is provided with an inclined abutment surface, and the abutment surface is provided with several limiting steps, any of which abuts against the bottom edge of the mounting hole.

[0018] The limiting step restricts the radial movement of the base within the mounting hole, and at the same time, the limiting step prevents the base from easily detaching from the mounting hole axially.

[0019] Furthermore, a third guide slope is provided at the bottom of the elastic protrusion, which guides the outer end of the elastic protrusion through the mounting hole.

[0020] The third guide slope facilitates the elastic clip to pass through the mounting hole using elastic deformation.

[0021] Furthermore, it also includes an end cap, the inner end of which has an inverted "convex" shaped protrusion. The inner end of the end cap is inserted into the receiving cavity from the end of the base assembly. The end cap and the base assembly are connected and fixed by screws. The bottom surface of the end cap has a communication port. The top of the end cap has a flip cover. The flip cover has convex shafts on both sides near the inner end. The corresponding inner sidewall of the end cap has shaft holes. The convex shafts are inserted into the shaft holes. The inner end of the top of the flip cover has a clearance step. The end cap has a limiting part that extends to the clearance step. The outer end of the flip cover flips upward around the convex shaft and opens. Under the action of gravity, the outer end of the flip cover falls down until the bottom surface of the limiting part and the clearance step abut against each other. The flip cover remains flat and covers the top opening of the end cap.

[0022] The end caps facilitate wiring for the base assembly. The flip-top design offers flexibility in use.

[0023] This utility model utilizes a snap-fit ​​connection between the base and the cover assembly, clamping the edges of the mounting holes to achieve assembly of the three components. The base can be placed inside the receiving cavity and assembled with the cover assembly, or the base and cover assembly can be assembled first and then installed into the base assembly. Assembly is completed without tools, making operation simple and convenient. The assembly process can be flexibly adjusted according to actual production conditions. With the base located inside the receiving cavity and only the cover assembly protruding from the socket assembly, the socket assembly is less prone to damage, thus reducing the overall size of the fixed track socket. The snap-fit ​​connection structure between the cover body and the base is rationally designed, making assembly labor-saving and easy. Attached Figure Description

The protruding edge and the resilient latching protrusion 50 clamp the edge of the mounting hole 10.

[0035] The faceplate assembly 21 includes a faceplate body 6 and a retaining ring 7. The outer diameter of the retaining ring 7 is larger than the maximum diameter of the mounting hole 10, forming the raised edge. An annular step 71 is provided on the inner circumference of the retaining ring 7, and the faceplate body 6 sits on the annular step 71.
