As shown in fig. 5 to 8, the electrical assembly structure includes the above-described fixing frame and the mounting base 40. The mounting seat 40 extends into the frame 10 of the fixing frame through the mounting opening 11 of the fixing frame and is matched with the clamping structure 20 in a clamping manner.

As shown in fig. 5 to 8, the mounting seat 40 has a rib 41 for engaging with the latch structure 20. A rib 41 is provided around the periphery of the mount 40. The rib 41 has a notch 411 provided corresponding to the clip 30 of the holder. Specifically, the top end surface of the rib 41 is the mounting surface 412, and when the mounting base 40 is clamped with the fixing frame, the mounting surface 412 is finally abutted to the supporting surface 23 of the clamping end of the clamping structure 20. Because each clamping structure 20 is provided with two clamping members 30, correspondingly, the ribs 41 on both sides of the mounting base 40 are provided with two notch portions 411.

As shown in fig. 1 to 2 and 5 to 6, the locking structure 20 of the fixing frame has a positioning slot 22. The mount 40 has positioning ribs 42 corresponding to the positioning grooves 22. After the mounting seat 40 is fastened to the fixing frame, the positioning rib 42 extends into the positioning groove 22 to form a positioning stop. Specifically, the positioning groove 22 is disposed in the middle of the clamping end of the clamping structure 20. Like this constant head tank 22 and first fretwork area 21 dig out the intermediate structure of joint end the back local rigidity reduction, and constant head tank 22 makes the middle deformation breach that exists of joint end, make the deformation along the installation direction of mount concentrate to the middle part in the installation, and joint spare 30 sets up the both ends at joint structure 20, can guarantee the location along the installation direction at both ends about the mount, thereby make the function failure that reduces the function spare and produce because of warping after the product installation, can also improve the gap between installation rear panel and the installation face.

As shown in fig. 5 and 8, the side of the mounting seat 40 away from the rib 41 has a limiting surface 43. After the mounting seat 40 is clamped with the fixing frame, the clamping piece 30 is abutted against the limiting surface 43, so that the mounting seat 40 is limited and stopped. At this time, the limiting surface 43 begins to be stressed, and the notch 411 on the other side of the limiting surface 43 begins to deform towards the stress direction of the limiting surface 43, so that an additional clamping installation space is generated.

In this embodiment, the hook-shaped engaging end of the fixing frame forms an inverted L-shaped interlocking structure with the mounting surface 412 and the limiting surface 43 of the mounting seat 40. The distance from the interlocking structure is controlled according to the requirement, so that the fixing frame plays a role in controlling in the installation and deformation process.

In the present embodiment, the assembly process of the mounting seat 40 and the fixing frame is as follows: the mounting seat 40 enters the mounting opening 11 along the mounting direction, and in the process, the edge of the mounting seat 40 sequentially extrudes the three guide surface segments 3211 outwards, so that the clamping member 30 deforms outwards. The mounting base 40 continues to move along the mounting direction, the rib 41 enters the accommodating space of the clamping end of the clamping structure 20, and the mounting surface 412 of the rib 41 is finally abutted against the supporting surface 23 of the clamping structure 20. At this time, the mounting seat 40 does not press the clip 30 any more, the clip 30 starts to reset from the outside deformation, and the clip 30 abuts against the limiting surface 43 of the mounting seat 40. Meanwhile, the positioning rib 42 of the mounting seat 40 is clamped in the positioning groove 22 of the clamping structure 20 to form a limiting stop, and the mounting seat 40 and the fixing frame are assembled.

In this embodiment, since the clip 30 is suspended in the second hollow area 24, when the function needs to be replaced, a tool can be used to extend into the second hollow area 24 from the back of the fixing frame to apply a force to the cantilever section 31, and the clip 30 deforms outward to disable the constraint on the function, so as to replace the function. Therefore, the front surface of the fixing frame can not be damaged when the fixing frame is disassembled at the back, and the product appearance can not be influenced. In addition, the cantilever section 31 makes the detachment of the clip member 30 more labor-saving by applying the lever principle.

The application also provides a switch socket, which comprises the electrical assembly structure. The switch jack also includes a faceplate. The panel cover is arranged on the functional part and is connected with the fixing frame in a buckling way. As shown in fig. 1, the faceplate is snap-fitted to the mount by a faceplate snap 50.

In this embodiment, a mounting simulation test was performed on the fixture of the switch socket, and compared with the fixture of the prior art. Wherein the installation simulated pressure is 500 newtons.

Table 1 mounting simulation test results of the fixing frame

As shown in table 1, test point a is at panel buckle 50; the test point B is the position of the clamping piece 30; the test point C is at the first hollow area 21 corresponding to the mounting hole 12. As can be seen from table 1, under the same installation simulation pressure, the amount of deformation of the middle portion of the fixing frame increases, and the amounts of deformation of the two ends of the fixing frame decrease. In order to reduce the functional failure caused by the deformation of the functional element after the switch socket is installed and improve the gap between the installed back panel and the installation surface, the clamping elements 30 of the fixing frame need to be arranged at the two ends of the clamping structure 20, and the distance from the clamping elements 30 to the end of the fixing frame is less than 1/4 of the length of the fixing frame in the extending direction of the clamping structure 20. The simulation test results provide experimental basis for the reasonable arrangement position of the clamping piece 30.

From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects: include framework 10 and joint structure 20 through the mount, the middle part of framework 10 has installation opening 11, framework 10 still has mounting hole 12, joint structure 20 is two, two joint structure 20 set up respectively on a set of relative side that sets up of installation opening 11, and each joint structure 20 extends along the side at its place, joint structure 20 includes first fretwork area 21, first fretwork area 21 corresponds the setting of mounting hole 12, set up first fretwork area 21 through the position that corresponds at joint structure 20 and mounting hole 12, when each parts assembly of switch socket or switch socket install in the position of use, make the deformation of the mount in the installation direction that produces when production assembly or installation concentrate to first fretwork area 21, thereby improve the deformation condition, reduce the failure rate of function piece, reduce the gap of installation back panel and installation face.
