[0002] Electrical connection is required between circuit boards. Generally, one circuit board is provided with pin headers, and the other circuit board is provided with socket headers. The electrical connection between the two circuit boards is achieved through the plugging of the pin headers and the socket headers.

[0003] Chinese Patent with the authorization announcement number CN208549099 discloses an intelligent thermostat, which includes a panel assembly, a base upper cover, and a base. The base is provided with pin headers, the base upper cover is fixedly connected to the base, the base upper cover is provided with pin header holes for the pin headers to pass through, the panel assembly is provided with socket headers, and the socket headers are plugged with the pin headers to achieve electrical connection.

[0004] When the above-mentioned socket headers are plugged with the pin headers, in order to ensure the accuracy of the plugging fit between the socket headers and the pin headers, the pin header holes on the base upper cover will first be in guiding fit with the outer wall surface of the socket headers, and then the accurate plugging of the socket headers and the pin headers will be achieved. However, during the guiding fit process between the pin header holes and the socket headers, a force will be generated between the two, and this force acts on the socket headers, which will cause the socket headers to deform, thereby affecting the stability of the conductive contact between the socket headers and the corresponding circuit boards. Summary of the Invention

[0005] The purpose of the present invention is to provide an electrical appliance housing assembly to solve the technical problem that when the socket headers are plugged with the pin headers in the prior art, a force will be generated between the pin header holes of the pin headers and the socket headers, and this force will cause the socket headers to deform; the purpose of the present invention is also to provide an electrical appliance connector plugging structure to solve the technical problem that when the socket headers are plugged with the pin headers in the prior art, a force will be generated between the pin header holes of the pin headers and the socket headers, and this force will cause the socket headers to deform; the purpose of the present invention is also to provide a thermostat to solve the technical problem that when the socket headers are plugged with the pin headers in the prior art, a force will be generated between the pin header holes of the pin headers and the socket headers, and this force will cause the socket headers to deform.

[0006] To achieve the above purpose, the technical solution of the electrical appliance housing assembly of the present invention is as follows:

[0007] The electrical appliance housing assembly includes:

[0008] A first housing unit, which is provided with pin header exposure holes for exposing the pin headers;

[0009] A second housing unit, which is provided with socket header exposure holes for exposing the socket headers;

[0010] The first housing unit and the second housing unit are separately arranged;

[0011] It is characterized in that

[0012] One of the first housing unit and the second housing unit is provided with a guiding protrusion, and the other is provided with a guiding hole.

[0013] The guiding protrusion and the guiding hole are used to form a plug connection prior to the pin header and the socket when the first housing unit and the second housing unit are assembled along the plugging direction of the pin header and the socket, so as to form positioning in the direction perpendicular to the plugging direction, thereby realizing the accurate plugging of the pin header and the socket.

[0014] The beneficial effect is that when the first housing unit and the second housing unit are assembled along the plugging direction of the pin header and the socket, the guiding protrusion and the guiding hole form a plug connection prior to the pin header and the socket, so as to form positioning in the direction perpendicular to the plugging direction, thereby realizing the accurate plugging of the pin header and the socket. Therefore, the pin header and the socket will not be subjected to acting forces, ensuring the stability of the conductive connection between the pin header and the socket and the corresponding circuit board, reducing the defective rate of the thermostat, and increasing the service life of the thermostat.

[0015] Further, the guiding protrusion is formed by an enclosing structure, and the enclosing space formed by the enclosing structure forms the pin header exposure hole or the socket exposure hole.

[0016] The beneficial effect is that the guiding protrusion can protect the pin header or the socket.

[0017] Further, the enclosing structure is a sleeve structure.

[0018] The beneficial effect is that in this way, the pin header can be better protected.

The positioning boss sinks into the positioning groove, so that the part of the panel assembly exposed outside the wall is less, increasing the aesthetics.

[0025] Further, the guiding protrusion is integrally formed on the first housing unit or the second housing unit, or the guiding protrusion is separately fixed on the first housing unit or the second housing unit.

[0087] The features and performance of the present invention will be further described in detail below in conjunction with embodiments.

[0088] Specific Embodiment 1 of the thermostat of the present invention:

[0089] As Figure 1 and Figure 2 shown, the thermostat includes a middle support hanger 1, a bottom case assembly 2, a panel assembly 3, and a decorative plate 4 arranged in sequence along the front-rear direction. The bottom case assembly 2 includes a bottom case housing and a socket 5 provided on the bottom case housing. The socket 5 is electrically connected to the circuit board in the bottom case housing; the panel assembly 3 includes a panel housing and a pin 7 provided in the panel housing. The pin 7 is electrically connected to the circuit board in the panel housing. In this embodiment, when the bottom case assembly 2 and the panel assembly 3 are assembled, the pin 7 is inserted into the socket 5 to achieve electrical connection between the circuit board of the bottom case assembly 2 and the circuit board of the panel assembly 3. Among them, the panel housing constitutes the first housing unit, and the bottom case housing constitutes the second housing unit.

[0090] In order to avoid phenomena such as bending, offset, and misalignment of the pin 7 caused by the long-term exposure of the pin 7 to the outside, as Figure 2 and Figure 4As shown, a guiding projection 8 is provided on the panel housing. The guiding projection 8 is formed by an enclosing structure. The enclosed space formed by the enclosing structure allows the pin header 7 to be exposed. The guiding projection 8 surrounds the pin header 7 to protect the pin header 7, avoiding problems such as smooth insertion and extraction caused by bending, offset, and misalignment of the pin header 7, as well as short circuits caused by contact between the pin headers 7, and improving the service life of the thermostat. Among them, the enclosed space of the guiding projection 8 constitutes a pin header exposure hole.

[0091] In this embodiment, the guiding projection 8 is of a sleeve structure, and the center line of the guiding projection 8 extends in the front-rear direction. This makes the processing of the guiding projection 8 relatively simple and can better protect the pin header 7. The pin header 7 retracts into the guiding projection 8, that is, the height of the guiding projection 8 is slightly higher than the height of the pin header 7, which can further protect the pin header 7.

[0092] The guiding projection 8 is integrally formed on the cover plate of the panel housing. The cover plate and the main board body of the panel housing are fixedly connected by fasteners. This not only facilitates the processing of the guiding projection 8 but also reduces the installation process and improves the production efficiency of the thermostat.

[0093] As Figure 1 、 Figure 3 and Figure 4 shown, a guiding hole 6 is provided on the bottom shell housing of the bottom shell assembly 2. The center line of the guiding hole 6 extends in the front-rear direction. The socket 5 retracts into the guiding hole 6, that is, the hole edge of the guiding hole 6 is slightly higher than the height of the socket 5. Such a design not only enables the guiding hole 6 to protect the socket 5 but also facilitates the guiding cooperation between the outer wall surface of the guiding projection 8 and the inner wall surface of the guiding hole 6 when the pin header 7 is inserted into the socket 5. Among them, the guiding hole 5 constitutes a socket exposure hole.

[0094] In this embodiment, the guiding hole 6 is provided on the cover plate of the bottom shell housing. The cover plate and the main board body of the bottom shell housing are fixedly connected by fasteners.

[0095] Chamfer structures are provided at the rear port edge of the guiding hole 6 and the front end of the guiding projection 8 to facilitate the guiding cooperation between the guiding projection 8 and the guiding hole 6. Among them, the chamfer structure is a rounded corner.

[0096] In order to enable the rapid guiding cooperation between the guiding hole 6 and the guiding projection 8, a positioning groove 10 is provided at the rear side of the bottom shell assembly 2, and a positioning boss 9 is provided on the panel assembly 3. The guiding hole 6 is located on the bottom wall of the positioning groove 10, and the guiding projection 8 is provided on the boss surface of the positioning boss 9. By pre-positioning and cooperating the positioning boss 9 with the positioning groove 10, the centering efficiency between the guiding projection 8 and the guiding hole 6 can be improved.

[0097] It should be noted that the distance between the convex surface of the positioning boss 9 and the edge of the positioning groove 10 is less than the distance between the end of the guiding protrusion 8 away from the positioning boss 9 and the edge of the guiding hole 6, and the distance between the end of the guiding protrusion 8 away from the positioning boss 9 and the edge of the guiding hole 6 is less than the distance between the pin header 7 and the socket 5.

[0098] When the panel assembly 3 and the bottom shell assembly 2 are assembled, the positioning boss 9 and the positioning groove 10 are pre-positioned and fitted, so that the guiding protrusion 8 and the guiding hole 6 are quickly aligned. Then, the outer wall surface of the guiding protrusion 8 and the inner wall surface of the guiding hole 6 are positioned and fitted, so that the relative positions of the pin header 7 and the socket 5 are corrected, and thus the insertion of the pin header 7 and the socket 5 is relatively smooth. After the panel assembly 3 and the bottom shell assembly 2 are snap-fitted and fixed, the pin header 7 and the socket 5 are fully inserted.

[0099] When the above-mentioned panel assembly 3 and bottom shell assembly 2 are assembled, as Figure 5 and Figure 6 shown, the guiding protrusion 8 and the guiding hole 6 are inserted first before the pin header 7 and the socket 5 to form a positioning in the direction perpendicular to the insertion direction, thereby realizing the accurate insertion of the pin header 7 and the socket 5. Therefore, the pin header 7 and the socket 5 will not be subjected to acting forces, ensuring the stability of the conductive connection between the pin header 7 and the socket 5 and the corresponding circuit board, reducing the defective rate of the thermostat, and increasing the service life of the thermostat.
