The present embodiment provides a wiring device, which is mainly composed of an operation handle 1, a decorative panel 2, a panel body 3, a cover 4, a reversing handle 5, and a body 6, taking the wall switch in fig. 1 as an example.

Wherein, after the installation, the operating handle 1 and the decorative panel 2 are positioned at the side of the user and can be observed by the user. The user can control the on-off of the switch circuit by pressing the upper end and the lower end of the operating handle 1. Specifically, the operating handle 1 is fixed on the reversing handle 5, the middle part of the reversing handle 5 is rotatably connected to the cover 4, and the middle part of the reversing handle 5 is coupled with a contact structure (not shown) inside the body 6 for controlling the circuit to be opened and closed, so that the contact structure inside the body 6 can be controlled to be disconnected and communicated through the transmission of the reversing handle 5 by utilizing the rotation of the operating handle 1.

Further, in order to accomplish the relative fixation between the structures of the operating handle 1, the decorative panel 2, and the like, and the fixation of the entire structure to the wall surface 8 (see fig. 3 to 6 described below), the wiring device in the present embodiment further includes a panel body 3. The panel body 3 is a structure like the Chinese character 'kou', the outer edge of the panel body 3 is close to the position of the second end 3b (back) of the panel body 3, a notch 302 for clamping and fixing the clamping jaw 202 on the decoration panel 2 is arranged, the clamping jaw 202 is arranged on the height direction of the decoration panel 2, for example, the clamping jaw can be arranged at the upper end and the lower end of the decoration panel 2 respectively, the clamping jaw 202 arranged at the upper end of the decoration panel 2 is not shown in figure 1 because of the observation angle, the inner edge of the panel body 3 can be clamped and fixed with the clamping structure 402 on the cover 4, and then the outer edge and the inner edge are used for fixing the panel body 3 and the decoration panel 2 and fixing the panel body 3 and. The panel body 3 further has a screw hole 304 capable of fixing with the wall surface 8, and the panel body 3 abutting against the wall surface 8 can be fixed with a bottom box (not shown) preset on the wall surface 8 by passing through the screw hole 304 by a screw, thereby completing the fixed connection of the wiring device and the wall surface 8.

In mounting the wiring device according to the present embodiment, it is necessary to first bring the second end 3b of the panel body 3 into contact with the wall surface 8 and to screw the panel body 3 to a bottom case (not shown) provided in the wall surface 8 (on the opposite side of the panel body 3 with respect to the wall surface 8) through a screw hole 304 in the panel body 3 for fixing the panel structure. Then, the decoration panel 2 is sleeved on the periphery of the panel body 3, and the claw 202 on the decoration panel 2 is clamped and fixed with the notch 302 of the panel body 3.

In some existing wiring devices, the clamping structure between the decoration panel 2 and the panel body 3 is shown in fig. 2, wherein the decoration panel 2 has a receiving groove 204 for receiving the panel body 3 of the wiring device, a claw 202 for clamping on the decoration panel 2 protrudes out of a side wall 206 of the receiving groove and is arranged at a notch of the receiving groove 204, the claw 202 adopted by the wiring device is provided with a chamfer on one side (right side) away from the bottom of the receiving groove 204, and the side (left side) close to the bottom of the receiving groove 204 is a plane perpendicular to the side wall 206 of the receiving groove.

Accordingly, the notch 302 for clamping on the panel body 3 is located at the outer edge of the second end 3b of the panel body 3, and when the first end 3a of the panel body 3 enters the receiving groove 204, the panel body 3 is clamped and fixed with the claw 202 on the decoration panel 2 by using the notch 302. Specifically, the panel body 3 is provided with the guide surface 306 on the left side of the notch 302, the chamfer on the right side of the claw 202 of the decoration panel 2 is matched, when the panel body 3 is guided to enter the accommodating groove 204, the elastic deformation of the decoration panel 2 made of plastic is utilized, the notch of the accommodating groove 204 of the decoration panel 2 is opened, when the decoration panel 2 and the panel body 3 are continuously close to each other, the claw 202 can cross the guide surface 306 on the left side of the notch 302, the notch 302 is released when the decoration panel 2 reaches, the elastic deformation generated in the guide process of the guide surface 306 at the moment is relieved, and the claw 202 can rebound and be clamped into the notch.

However, in some scenarios, for example, when the bottom case is disposed relatively deep, or when a decorative layer such as wallpaper 7 is additionally attached to the surface of the wall surface during the decoration process, referring to fig. 3, the surface plane of the wall surface will be raised (shifted to the left). If the existing wiring harness is installed in these scenarios, the pawl 202 will be prevented from moving further to the right when it is moved to the left of the recess 302 against the surface of the wallpaper 7 (or the surface plane of the raised wall surface), and will not be able to get stuck into the recess 302. At this moment, only need to add the application of force to the decoration panel 2 to the left side slightly, can take off decoration panel 2, be difficult to by fixed between decoration panel 2 and the panel body 3, the fixed mechanical properties of its joint descends seriously, can't satisfy the standard requirement.

In order to solve the above problem, in the clamping structure between the decorative panel 2 and the panel body 3 of the wiring device according to the present embodiment, as shown in fig. 4, the decorative panel 2 has an accommodating groove 204 for accommodating the panel body 3 of the wiring device, and the claw 202 protrudes from a side wall 206 of the accommodating groove and is disposed at a notch of the accommodating groove 204. The panel body 3 has a first end 3a and a second end 3b along the thickness direction, and a notch 302 is arranged at the outer edge 3b of the second end and at the position matched with the claw 202, when the first end 3a of the panel body 3 completely enters the accommodating groove 204 of the decoration panel 2, the notch 302 can be matched with the claw 202 on the decoration panel 2, and the panel body 3 and the decoration panel 2 are clamped and fixed.

Unlike the wiring tool in the related art, in the present embodiment, the claw 202 of the decorative panel 2 is configured in a stepped structure on its side close to the bottom of the accommodating groove 2.

The stepped structure is a two-step having a step surface parallel to the side wall 206 of the receiving groove and a step surface perpendicular to the side wall 206 of the receiving groove, wherein the step surface perpendicular to the side wall 206 of the receiving groove (i.e., perpendicular to the depth direction of the receiving groove 204) constitutes the engagement surface of the pawl 202. The clamping surface of the latch 202 includes a first clamping surface 202a and a second clamping surface 202b distributed at different positions in the depth direction of the receiving groove 204, and the latch 202 can be alternatively clamped and fixed with the recess 302 of the panel body 3 by using the first clamping surface 202a or the second clamping surface 202 b.

Specifically, referring to fig. 5, when the height of the surface plane of the wall surface 8 is normal, the decorative panel 2 can be snap-fitted with the first snap-fit surface 202a of the claw 202 and the notch 302 of the panel body 3.

For some scenes that the height of the surface plane of the wall surface 8 is raised, taking fig. 6 as an example, fig. 6 is a scene that the wall surface 8 is attached with the wallpaper 7, when the wiring device provided by the present embodiment is installed in the scene, even if the first clamping surface 202a cannot be clamped into the recess 302, the second clamping surface 202b can still be used as a better clamping surface to be clamped into the recess 302 of the panel body 3, and the clamping has a certain strength, so that the mechanical property of the clamping fixation between the decoration panel 2 and the panel body 3 can still be maintained at a higher standard without being too severely lowered.

In addition, as the clamping part on the left side of the clamping jaw 202 is configured to be of a stepped structure, the clamping jaw with the stepped structure has good mechanical strength, is not easy to bend, and has high clamping mechanical property; in addition, in a scene that the surface plane of the wall surface 8 is raised, referring to fig. 6, the decoration panel 2 is elastically deformed, and an elastic force generated by the elastic deformation can be applied to the outer edge 3c of the panel body through the claw step surface 202c perpendicular to the clamping surface (i.e. parallel to the side wall 206 of the receiving groove) to give the panel body 3a force for pressing the panel body, which can further improve the mechanical property of clamping fixation.

Further, in the present embodiment, since the stepped structure is configured as a step of two layers, accordingly, the number of the chucking surfaces is also two (the first chucking surface 202a and the second chucking surface 202 b). Therefore, the width of the step surface (d 1, d2, respectively) occupied by the first clamping surface 202a and the second clamping surface 202b can be wider, and by reasonably distributing the width d1 of the first clamping surface 202a and the width d2 of the second clamping surface 202b, the magnitude of the pressing force and the width of the step surface for clamping can be reasonably balanced. Referring to fig. 4 and 6, when the width d1 of the first clamping surface 202a is increased, in the case that the surface plane of the wall surface 8 is raised, when the decorative panel 2 is clamped and fixed only by the second clamping surface 202b, the amount of deformation of the elastic deformation generated by the decorative panel 2 is increased with the increase of d1, so that the pressing force between the decorative panel 2 and the panel body 3 is increased, and the width of the step surface (second clamping surface 202b) for clamping is decreased. In this embodiment, d1 ═ d2, in another embodiment of the present invention, the size of d1 and d2 may be adjusted according to actual needs to have a certain width difference between them, so as to balance the influence of the pressing force and the width of the step surface on the mechanical properties of the clamping fixation. Furthermore, in other embodiments of the present invention, the number of the clamping surfaces may be configured to be more than two, and the number of the clamping surfaces may be increased to facilitate the detachment.

In the present embodiment, the first engaging surface 202a and the second engaging surface 202b are spaced apart by 1mm or more in the depth direction of the receiving groove 204 (see fig. 4, i.e., the left-right direction in fig. 4). This difference in distance in the depth direction ensures that the second engagement surface 202b of the wiring device can still be inserted into the recess 302 even when the surface plane of most of the wall surface 8 is raised, and the fastening of the decorative panel 2 to the panel body 3 is completed.

In another embodiment of the present invention, the notch 302 of the panel body 3 of the wiring device may be configured to have a stepped structure. Referring specifically to fig. 7, the recess 302 at the second end 3b of the panel body 3 is configured as a two-layer stepped structure having a step surface parallel to the outer edge 3c of the panel body and a step surface perpendicular to the outer edge 3c of the panel body, wherein the step surface perpendicular to the outer edge 3c of the panel body is configured as a clamping surface of the recess 302, including third and fourth clamping surfaces 302a and 302b distributed at different positions of the panel body 3 in the thickness direction thereof. The third clamping surface 302a and the fourth clamping surface 302b are perpendicular to the thickness direction of the panel body 3, and the notch 302 can alternatively use the third clamping surface 302a or the fourth clamping surface 302b to receive the jaw 202 of the trim panel 2 so as to be clamped and fixed with the trim panel 2.

Specifically, referring to fig. 8, when the surface plane height of the wall surface 8 is normal, the panel body 3 can be snap-fixed with the claws 202 of the trim panel 2 using the third snap-in surfaces 302a of the recesses 302.

For some scenes that the height of the surface plane of the wall surface 8 is raised, taking fig. 9 as an example, fig. 9 is a scene that the wall surface 8 is attached with the wallpaper 7, when the wiring device provided by the present embodiment is installed in the scene, even if the claw 202 cannot be clamped to the third clamping surface 302a of the recess 302, the fourth clamping surface 302b of the recess 302 can still be used as a better clamping surface to receive the claw 202, and the clamping has a certain strength, so that the mechanical property of the clamping fixation between the decoration panel 2 and the panel body 3 can still be maintained at a higher standard without being too seriously lowered.

Similarly to the step structure provided on the claw 202, in the present embodiment, the decorative panel 2 can also utilize the elastic deformation thereof to give the panel body 3a force for pressing the decorative panel, and the force can also be adjusted by adjusting the widths of different step surfaces of the step structure on the notch 302, so as to balance the influence of the magnitude of the pressing force and the width of the clamping surface on the mechanical property of the clamping fixation. In addition, in the present embodiment, the third engaging surface 302a and the fourth engaging surface 302b are spaced apart by more than 1mm in the thickness direction of the panel body, so that the claw 202 of the wiring device can still extend to the fourth engaging surface 302b of the recess 302 to complete the engaging and fixing under the condition that the surface plane of most of the wall surface 8 is raised.

In another embodiment of the present invention, the side of the claw 202 near the bottom of the receiving groove 204 and the notch 302 can be configured as a step structure with the same number of clamping surfaces. Referring to fig. 10, in this embodiment, the pawl 202 and the recess 302 are each configured with two snap surfaces. In the scene that the surface plane of the wall surface 8 is not raised, the two clamping surfaces of the clamping jaw 202 can be abutted against the two clamping surfaces of the notch 302 at the same time, that is, the clamping jaw 202 can be clamped and fixed by using the "clamping surface combination" formed by the two clamping surfaces and the "clamping surface combination" formed by the two clamping surfaces of the notch 302, so as to improve the mechanical property of clamping between the clamping jaw 202 and the notch 302 in the scene that the surface plane of the wall surface 8 is not raised.

In addition, referring to fig. 11, in other embodiments of the present invention, the claw 202 may also be formed to protrude from the sidewall 206 of the receiving groove and have a structure of a plurality of protrusions with different protruding heights. The height of the protrusion gradually decreases from shallow to deep (from right to left) in the depth direction of the receiving groove 204. Through the above manner, the clamping jaw 202 may also form a plurality of clamping surfaces (corresponding to the left side surfaces of the protrusions) distributed along the depth direction of the receiving groove 204, and the clamping jaw 202 may be clamped and fixed with the panel body by selecting different clamping surfaces or clamping surface combinations from the plurality of clamping surfaces.

It should be noted that the term "wiring device" in this document should be understood to include at least "switch", "socket", or a combination thereof. Preferably, the wiring device may be one or a combination of wall switch, wall socket, electronic switch and information socket.

So far, the technical solution of the present invention has been described with reference to the accompanying drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
