In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, in the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0052] like Figures 1 to 9As shown, at least one embodiment provides a housing for a controller, including a rectangular housing 1 and an interface 2, wherein the housing 1 includes a panel 101 and a back panel 102 arranged in parallel, and the interface 2 is exposed on the bottom plate of the housing 1. The edges where the two wide sides of the back panel 102 are located are the first edges 103, and the edges where the upper long side is located are the second edges 104. The female clamping part 3 includes a first groove wall 301, a positioning inner wall 302, a positioning hole 303 and a positioning guide block 304, wherein the first groove wall 301 is vertically connected to the positioning inner wall 302 and is embedded in the first edge 103 of the housing 1 to form a right-angled groove, and the positioning guide block 304 protrudes from the first groove wall 301 and is spaced apart from the positioning inner wall 302. The right-angled groove includes a connected guide space 307 and a positioning space 308, wherein the guide space 307 is located above the positioning guide block 304, and the positioning space 308 is located between the positioning inner wall 302 and the positioning guide block 304. In this embodiment, two female clamping parts 3 are arranged on each first edge 103, and male clamping parts 4 corresponding to the female clamping parts 3 are arranged on the panel 101. The male clamping part 4 includes a first body 402 fixed with a spherical plunger 401 and a clamping part 403 protruding inwardly from the first body 402, a part of the ball head of the spherical plunger 401 protrudes from the first body 402 in a direction perpendicular to the panel, and the first body 402 is detachably fixed to the panel 101 by screws.

[0053] In some embodiments, an elastic member is disposed inside the spherical plunger to lift the ball head.

[0054] When two controllers are connected, first, the male connector 4 is inserted into the guide space 307 of the female connector 3 in a direction perpendicular to the back plate 102, and then the clamping portion 403 is inserted into the positioning space 308 in a direction parallel to the first edge 103. Since the positioning inner wall 302 is provided with a positioning hole 303, the ball head of the spherical plunger 401 is embedded in the positioning hole 303, and the positioning hole 303 presses the ball head of the spherical plunger 401 so that the spherical plunger 401 generates an elastic force, and the elastic force presses the clamping portion 403 against the positioning guide block 304. The elastic force of the spherical plunger 401 not only positions the two controllers relative to each other in a direction perpendicular to the back plate 102, but also, due to the friction between the positioning guide block 304 and the clamping portion 403 and the pressure and friction between the ball head and the positioning hole 303, the two controllers can also constrain each other's positions in a plane parallel to the back plate.

[0055] In some embodiments, the vertical distance between the center of the ball head of the spherical plunger 401 and the outer wall of the first body 402 is equal to the vertical distance between the center of the positioning hole 303 and the side wall of the shell 1, so that when the clamping portion 403 is limited in the positioning space 308, the outer wall of the first body 402 is flush with the side wall of the shell 1, making the multiple controllers appear more neat and beautiful after connection.

[0056] In some embodiments, an inclined first wedge surface 305 is provided on the positioning guide block 304, and an inclined second wedge surface 404 is provided on the clamping portion 403. When the clamping portion 403 enters the positioning space 308, the friction between the clamping portion 403 and the positioning guide block 304 increases due to the force between the ball head of the spherical plunger 401 and the positioning inner wall 302. Then, the first wedge surface 305 and the second wedge surface 404 can be used to guide the clamping portion 403 to be inserted into the positioning space 308 more smoothly. In addition, in order to guide the ball head to be smoothly embedded in the positioning hole 303, a guide groove 309 adapted to the front end of the ball head of the spherical plunger is provided on the positioning inner wall 302. The length direction of the guide groove 309 is parallel to the first edge 103, and the guide groove 309 extends to the positioning hole 303.

[0057] In some embodiments, in order to provide a certain supporting force to the male clamping member 4 , the positioning guide block 304 extends a supporting bottom 306 for supporting the first body 402 .

[0058] In order to strengthen the connection reliability between the controllers, a female connector 5 is provided at the second edge 104 of the back plate 102. The female connector 5 includes a slide groove and two retaining edges 501 embedded in the second edge 104 of the housing 1. The slide groove includes a slide groove wall 502 and a third groove wall 503 connected vertically. The slide groove wall 502 is parallel to the back plate 102, and the third groove wall 503 is parallel to the second edge 104. Two retaining edges 501 extend from the two side walls of the slide groove into the slide groove, and the retaining edges 501 are spaced apart from the slide groove wall 502. The male connector 6 includes a second body 601 and two wing edges 602 protruding from both sides of the second body 601. An inclined third wedge surface 603 is provided on the wing edge 602. The third wedge surface 603 is used to smoothly insert the male connector 6 into the slide groove. The second body 601 is detachably fixed to the panel 101 by screws from the back side of the panel 101. While the snap-fit ​​portion 403 is inserted into the positioning space 308, the male connector 6 is inserted into the slide groove, and the elastic force of the spherical plunger 401 is utilized to limit the wing edge 602 and the retaining edge 501 to each other in a direction perpendicular to the back plate 102, thereby further increasing the connection between the two signal acquisition controllers.

[0059] This signal acquisition controller has improvements in production cost, durability, safety and scope of application. The specific beneficial effects are summarized as follows:

[0060] Reduce production costs:

[0061] By designing the snap fastener as a detachable independent component, the traditional one-piece molding process is avoided, material waste is reduced, and production costs are lowered.

[0062] Improved durability and serviceability:

[0063] The independent design of the fastener means that when the fastener is damaged, there is no need to replace the entire cavity. Only the damaged fastener needs to be replaced, which reduces maintenance costs and increases the service life of the product.

[0064] The use of screw fixing makes it easy to quickly disassemble and repair, improving the product's user experience and maintenance convenience.

[0065] Enhanced safety and robustness:

[0066] The design of a spherical plunger and a positioning hole is adopted, and the buckle can be firmly fixed in both vertical and horizontal directions through elastic force, avoiding the buckle from falling off during sliding and improving safety.

[0067] The limit design of the card connector is added to effectively prevent the controller from sliding or falling off during use, thereby improving the stability and safety of the overall structure.

[0068] Expand the scope of application:

[0069] The improved buckle structure increases the engagement area and limiting force of the clip, making it applicable to more and heavier products and expanding the application range of the controller.

[0070] Multiple female and male card-joint parts are provided to enhance the connection firmness between signal acquisition controllers and ensure stable use in different application scenarios.

[0071] Improve installation efficiency and convenience:

[0072] The inclined wedge surface design makes it easier for the clamping part to enter the positioning space, reduces the resistance during the installation process, and improves the installation efficiency.

[0073] The bottom support design provides additional support, making the snap-on connector more stable during installation, thus improving the convenience and reliability of installation.

[0074] Through the above improvements, the utility model is superior to the prior art in terms of production cost, durability, safety and scope of application, and has significant beneficial effects.
