Description

Technical Field

[0001] This invention relates to the field of electrical device technology, specifically a switch socket with replaceable functional modules. Background Technology

[0002] Switches and sockets are electrical switches and sockets installed on walls for connecting and disconnecting electrical circuits. Sometimes they also serve a decorative function for aesthetic purposes. The quality of switches and sockets determines their safety and directly affects household electrical safety. Some existing switches and sockets incorporate functional modules such as Bluetooth, voice, and USB to enable more functions within their structure.

[0003] To facilitate the installation and removal of functional modules inside the switch and socket, the switch and socket have mounting slots for placing functional modules. After the functional module is placed in the mounting slot, terminal connections are required. Connecting the terminal to the functional module is quite troublesome when installing and removing it. In particular, if the operator forgets to remove the terminal when removing the functional module, it can easily damage the terminal and terminal block, affecting the use of the entire switch, socket and functional module. Summary of the Invention

[0004] The purpose of this invention is to provide a switch socket with replaceable functional modules to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A switch socket with replaceable functional modules includes a switch socket body, at least one functional module assembly, and a power connection cable disposed at one end of the switch socket body. The switch socket body has an internal cavity for accommodating the functional module assembly. The functional module assembly includes a functional module body, a rear end plate, and a row of front connection terminals. The functional module body is inserted into the cavity. The front connection terminals are located at the end of the functional module body within the cavity. The rear end plate is located at the other end of the functional module body and is detachably and securely connected to the port of the cavity. The cavity has a partition plate with a communication opening for the front connection terminals to pass through. The front end of the placement cavity is divided into a clamping cavity. The clamping cavity has two opposing elastic clamping mechanisms. One end of each elastic clamping mechanism passes through a partition plate and extends into the placement cavity. When the functional module body is inserted into the placement cavity, the end of the functional module body abuts against the ends of the two elastic clamping mechanisms. Under the push of the functional module body, the part of the elastic clamping mechanism in the clamping cavity can clamp the end of the front connecting terminal that extends into the clamping cavity. The end of the switch socket body away from the port of the placement cavity has a connecting cavity. The connecting cavity has a terminal block assembly inside. The connection part of the terminal block assembly and the front connecting terminal extends into the corresponding clamping cavity.

[0007] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0008] In one alternative embodiment: the terminal block assembly includes an electrical connector, a terminal mounting base, a terminal plug-in portion, and at least one adjusting screw. The side wall of the electrical connector is slidably fitted with the inner wall of the connecting cavity. The terminal mounting base is disposed on the end face of the electrical connector. One end of the terminal mounting base passes through the partition between the clamping cavity and the electrical connector and extends into the interior of the clamping cavity. The end of the terminal mounting base located in the clamping cavity has multiple terminal plug-in portions opposite to the front connecting terminals. The adjusting screw is disposed at the end of the switch socket body and is helically fitted with the side wall of the connecting cavity. The end of the adjusting screw extending into the connecting cavity is rotatably connected to the electrical connector. The outer end of the adjusting screw located in the connecting cavity has a rotating wheel.

[0009] In one alternative embodiment: the elastic clamping mechanism includes a clamping slider, at least one elastic abutment rod, and multiple clamping parts. The clamping slider slides inside the connecting cavity, and the upper end face of the clamping slider is inclined. The inclined surface of the clamping slider has at least one connecting slide rail, and the connecting slide rail is provided with a push-pull sliding seat that slides on it. One end of the elastic abutment rod is connected to the push-pull sliding seat, and the other end of the elastic abutment rod passes through the partition plate and extends into the placement cavity. Multiple clamping parts are arranged side by side on the end faces of the clamping slider opposite to another clamping slider. When the clamping parts on the opposite end faces of the two clamping sliders are close together, they can form a clamp to lock the front connecting terminal.

[0010] In one alternative embodiment: the elastic abutment rod includes an abutment strip, a push-pull guide rod, and a return spring. One end of the push-pull guide rod is hinged to the push-pull sliding seat, and the other end slides through the partition plate. The abutment strip is located at the end of the push-pull guide rod that extends into the placement cavity and is used to abut against the end of the functional module body. One end of the return spring is connected to the side of the abutment strip, and the other end is connected to the side of the partition plate.

[0011] In one alternative embodiment: the clamping part includes a fixed base, a clamping plate, and rubber friction-enhancing strips. The fixed base is fixed to the end face of the clamping slider, the clamping plate is semi-circular and fixed to the end of the fixed base, and the rubber friction-enhancing strips are multiple and evenly distributed on the inner arc wall of the clamping plate.

[0012] In one alternative: the inner wall of the placement cavity is provided with multiple lateral grooves, and each lateral groove is equipped with a retaining ball that protrudes from the port of the lateral groove. The retaining ball is connected to the inner wall of the lateral groove by a shock-absorbing spring.

[0013] In one alternative: side plates are provided on both outer side walls of the switch socket body, and the lower end of the side plate is elastically rotatably connected to the side wall of the switch socket body through a spring-loaded rotating seat. The side plate is provided with multiple cross-shaped connection ports.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In this invention, the elastic clamping mechanism uses the insertion of the functional module component into the placement cavity as a thrust to clamp and fix the front connecting terminal, and ensures that the position of the front connecting terminal accurately corresponds to the terminal block component, which facilitates the electrical connection between the functional module component and the components in the switch socket.

[0016] 2. In this invention, when the main body of the functional module is removed from the placement cavity, the two elastic clamping mechanisms can be elastically reset, so that the two elastic clamping mechanisms move away from each other and do not clamp the front connecting terminal. The front connecting terminal can be removed from the placement cavity along with the main body of the functional module, thereby facilitating the separation and replacement of the functional module components.

[0017] 3. The present invention has a simple structure, can quickly realize the installation and separation of functional module components, and ensures that the terminal connection is stable and accurate, making it easy to use and highly practical. Attached Figure Description

Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. In the drawings or description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this invention are merely illustrative and not intended to limit the scope of the invention. Any obvious modifications or changes made to this invention do not depart from the spirit and scope of the invention.

[0024] In one embodiment, such as Figures 1-3As shown, a switch socket with replaceable functional modules includes a switch socket body 100, at least one functional module assembly 200, and a power connection cable 400 disposed at one end of the switch socket body 100. The switch socket body 100 has a placement cavity 110 for accommodating the functional module assembly 200. The functional module assembly 200 includes a functional module body 210, a rear end plate 220, and a row of front connection terminals 230. The functional module body 210 is inserted into the placement cavity 110. The front connection terminals 230 are disposed at the end of the functional module body 210 located inside the placement cavity 110. The rear end plate 220 is disposed at the other end of the functional module body 210 and is detachably and securely connected to the port of the placement cavity 110. The placement cavity 110 has a partition plate 160 with a communication opening 180 for the front connection terminals 230 to pass through. The partition plate 160 divides the placement cavity... The front end of 110 is divided into a clamping cavity 170. The clamping cavity 170 has two opposing elastic clamping mechanisms 500. One end of each elastic clamping mechanism 500 passes through the partition plate 160 and extends into the placement cavity 110. When the functional module body 210 is inserted into the placement cavity 110, the end of the functional module body 210 abuts against the ends of the two elastic clamping mechanisms 500. Under the push of the functional module body 210, the portion of the elastic clamping mechanism 500 in the clamping cavity 170 can clamp the end of the front connecting terminal 230 that extends into the clamping cavity 170. The end of the switch socket body 100 away from the port of the placement cavity 110 has a connecting cavity 120. The connecting cavity 120 has a terminal block assembly inside. The connection portion of the terminal block assembly and the front connecting terminal 230 extends into the corresponding clamping cavity 170.

[0025] In this embodiment of the invention, the functional module body 210 is inserted into the corresponding placement cavity 110 and is fastened to the end face of the switch socket body 100 via the rear end plate 220. The front connection terminal 230 passes through the connecting port 180 and gradually extends into the clamping cavity 170. The end of the functional module body 210 extending into the placement cavity 110 presses against the ends of the two elastic clamping mechanisms 500 extending into the placement cavity 110. Under the push of the functional module body 210, the two elastic clamping mechanisms 500 move relative to each other and gradually clamp a row of front connection terminals 230, thus fixing the position of the front connection terminals 230. By adjusting the terminal block assembly in the connection... The position inside the cavity 120 allows the portion of the terminal block assembly extending into the clamping cavity 170 to move toward the front connecting terminal 230. Since the front connecting terminal 230 is clamped and kept in a stable position by the two elastic clamping mechanisms 500, the terminal block assembly and the front connecting terminal 230 are accurately and securely connected. When the functional module body 210 is removed from the placement cavity 110, the two elastic clamping mechanisms 500 can elastically reset, thereby moving away from each other and no longer clamping the front connecting terminal 230. The front connecting terminal 230 can be removed from the placement cavity 110 along with the functional module body 210, thus facilitating the separation and replacement of the functional module assembly 200.

[0026] In one embodiment, such as Figure 2 and Figure 3As shown, the terminal block assembly includes an electrical connector 130, a terminal mounting base 131, a terminal insertion portion 132, and at least one adjusting screw 140. The side wall of the electrical connector 130 is slidably engaged with the inner wall of the connecting cavity 120. The terminal mounting base 131 is disposed on the end face of the electrical connector 130. One end of the terminal mounting base 131 passes through the partition between the clamping cavity 170 and the electrical connector 130 and extends into the clamping cavity 170. The end of the terminal mounting base 131 located in the clamping cavity 170 has multiple terminal insertion portions 132 opposite to the front connecting terminals 230. The adjusting screw 140 is disposed at the end of the switch socket body 100 and is helically engaged with the side wall of the connecting cavity 120. The end of the adjusting screw 140 extending into the connecting cavity 120 is rotatably connected to the electrical connector 130. The end of the adjusting screw 140 located outside the connecting cavity 120 has a rotating... Rotating wheel 150; In this embodiment of the invention, turning the rotating wheel 150 causes the adjusting screw 140 to rotate, and the adjusting screw 140 can be screwed into or out of the connecting cavity 120; when the adjusting screw 140 is screwed into the connecting cavity 120, the adjusting screw 140 pushes the electrical connector 130 and causes the terminal mounting base 131 to move toward the clamping cavity 170; thereby the terminal plug 132 moves toward the front connecting terminal 230 clamped by the two elastic clamping mechanisms 500 and connects to the front connecting terminal 230; when the adjusting screw 140 is gradually screwed out of the connecting cavity 120, the adjusting screw 140 pulls the electrical connector 130 back and causes the terminal plug 132 to disengage from the front connecting terminal 230; thereby, by turning the rotating wheel 150, the electrical connection between the control function module assembly 200 and the electrical connector 130 and other electrical components inside the switch socket body 100 can be realized.

[0027] In one embodiment, such as Figure 3 and Figure 4As shown, the elastic clamping mechanism 500 includes a clamping slider 510, at least one elastic abutment rod, and multiple clamping portions 570. The clamping slider 510 slides inside the connecting cavity 120, and its upper end face is inclined. At least one connecting slide rail 520 is provided on the inclined surface of the clamping slider 510, and a push-pull sliding seat 530 is provided on the connecting slide rail 520 for sliding. One end of the elastic abutment rod is connected to the push-pull sliding seat 530, and the other end of the elastic abutment rod passes through the partition plate 160 and extends into the placement cavity 110. Multiple clamping portions 570 are arranged side-by-side on the end faces of the clamping slider 510 and another clamping slider 510. When the clamping portions 570 on the opposite end faces of the two clamping sliders 510 are close together, they can form a clamping clamp on the front connecting terminal 230. In this embodiment of the invention, the functional module body 210... The insertion of the elastic abutment rod into the placement cavity 110 and its end abutting against the end of the placement cavity 110 are both present. The elastic abutment rod moves toward the clamping cavity 170 under the push of the functional module body 210. The elastic abutment rod pushes the push-pull sliding seat 530 to move laterally on the connecting slide rail 520. Since the push-pull sliding seat 530 moves laterally and the upper end surface of the clamping slider 510 is inclined, the push-pull sliding seat 530 pushes the clamping slider 510 toward the middle of the clamping cavity 170. Therefore, the two clamping parts 570 can move relative to each other and clamp the front connecting terminal 230. When the functional module body 210 is pulled out of the placement cavity 110, the elastic abutment rod can reset and pull the clamping slider 510 to reset. As a result, the two clamping parts 570 move away from each other, thereby loosening the front connecting terminal 230 and facilitating the disengagement of the front connecting terminal 230 from the terminal insertion part 132.

[0028] In one embodiment, such as Figure 4 As shown, the elastic abutment member includes an abutment strip 540, a push-pull guide rod 550, and a return spring 560. One end of the push-pull guide rod 550 is hinged to the push-pull sliding seat 530, and the other end slides through the partition plate 160. The abutment strip 540 is located at the end of the push-pull guide rod 550 that extends into the placement cavity 110 and is used to abut against the end of the functional module body 210. One end of the return spring 560 is connected to the side of the abutment strip 540, and the other end is connected to the side of the partition plate 160. In this embodiment of the invention, the abutment strip 540 abuts against the end of the functional module body 210 in a face-to-face contact manner to avoid concentrated force. When the abutment strip 540 is not pushed by the functional module body 210, the return spring 560 can drive the push-pull guide rod 550 and the clamping slider 510 to automatically return to their original positions through its own elasticity.

[0029] In one embodiment, such as Figure 4As shown, the clamping part 570 includes a fixing base 571, a clamping piece 572, and a rubber friction-enhancing strip 573. The fixing base 571 is fixed to the end face of the clamping slider 510. The clamping piece 572 is semi-circular and fixed to the end of the fixing base 571. There are multiple rubber friction-enhancing strips 573, which are evenly distributed on the inner arc wall of the clamping piece 572. In this embodiment of the invention, the clamping piece 572 is semi-circular so that when two clamping pieces 572 are fastened together, they form a circular clamp, which increases the firmness of clamping the front connecting terminal 230. The rubber friction-enhancing strip 573 can increase the friction between the clamping piece 572 and the outer wall of the front connecting terminal 230, while avoiding scratching the outer wall of the front connecting terminal 230.

[0030] In one embodiment, such as Figure 2 and Figure 3 As shown, the inner wall of the placement cavity 110 is provided with a plurality of lateral grooves 111, and each lateral groove 111 is equipped with a partially protruding ball bearing 112. The ball bearing 112 is connected to the inner wall of the lateral groove 111 by a shock-absorbing spring 113. In this embodiment of the invention, when the functional module body 210 is pulled out or inserted into the placement cavity 110, the side wall of the functional module body 210 rolls in contact with the ball bearing 112, thereby reducing wear. Since the shock-absorbing spring 113 has elastic buffering, it can buffer the vibration of the functional module body 210 caused by the impact of the switch socket body 100, thereby achieving a shock absorption effect.

[0031] In one embodiment, such as Figure 1 As shown, side plates 300 are provided on both outer side walls of the switch socket body 100. The lower end of the side plate 300 is elastically rotatably connected to the side wall of the switch socket body 100 through a spring-loaded rotating seat 310. The side plate 300 is provided with multiple cross-shaped connection ports 320. In this embodiment of the invention, since the side plate 300 is rotatably engaged with the side wall of the switch socket body 100, the side plate 300 can be unfolded and, through the engagement of the connection ports 320 with other fasteners, the entire switch socket can be fixed or hooked. When it is not necessary to fix the switch socket, the side plate 300 can be attached to the side wall of the switch socket body 100, reducing the space occupied.

[0032] The above embodiment provides a switch socket with replaceable functional modules. The functional module body 210 is inserted into the corresponding placement cavity 110 and fastened to the end face of the switch socket body 100 via a rear end plate 220. The front connecting terminal 230 passes through the connecting port 180 and gradually extends into the clamping cavity 170. The end of the functional module body 210 extending into the placement cavity 110 presses against the ends of two elastic clamping mechanisms 500 extending into the placement cavity 110. Under the push of the functional module body 210, the two elastic clamping mechanisms 500 move relative to each other and gradually clamp a row of front connecting terminals 230, fixing the position of the front connecting terminals 230. By adjusting... The position of the terminal block assembly inside the connecting cavity 120 allows the portion of the terminal block assembly extending into the clamping cavity 170 to move toward the front connecting terminal 230. Since the front connecting terminal 230 is clamped and kept in a stable position by two elastic clamping mechanisms 500, the terminal block assembly and the front connecting terminal 230 are accurately and firmly connected. When the functional module body 210 is removed from the placement cavity 110, the two elastic clamping mechanisms 500 can elastically reset, thereby moving away from each other and no longer clamping the front connecting terminal 230. The front connecting terminal 230 can be removed from the placement cavity 110 along with the functional module body 210, thus facilitating the separation and replacement of the functional module assembly 200.

[0033] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
