Description

Technical Field

[0001] The present application belongs to the field of relay technology, and in particular relates to an expandable combined relay. Background Art

[0002] Relay expansion is generally achieved by adding new relays, which usually requires certain hardware support. When the hardware is installed on the circuit board, if several relays need to be replaced, the entire hardware needs to be removed before the corresponding relays can be removed.

[0003] Therefore, for a single circuit board, if a single relay is installed, it is easy to disassemble due to its small size and few structures. However, if multiple relays are installed together, disassembly is also more troublesome. Although a combination relay that is convenient for expansion is proposed in the prior art, such as Chinese Utility Model Patent No. 202320825644.9, which discloses a combination relay that is convenient for expansion, it is required to install some components that are convenient for connection and disassembly on the relay body. Since the relay components themselves are relatively precise, these precise small components for card disassembly and connection are also required, which puts certain requirements on processing, and therefore the manufacturing cost is also relatively high. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an expandable combined relay in order to solve the problem of high manufacturing cost in the prior art.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] An expandable combined relay includes a relay body and a mounting frame for mounting a plurality of relay bodies. The relay bodies are mounted on corresponding positions of electronic components via the mounting frame. The mounting frame includes a base, a plurality of rotating assemblies, and a plurality of detachable assemblies. The plurality of rotating assemblies and the plurality of detachable assemblies are connected one by one.

[0007] The relay body is installed on the rotating assembly through a detachable assembly, which is convenient for disassembly. The rotating assembly rotates under the action of external force to facilitate adjustment of the installation angle; the rotating assembly includes a groove, a connecting column, a fixing plate, a rubber pad, and a fixing seat opened on the base. A mounting hole is opened in the groove, the connecting column is passed through the mounting hole, and a rubber pad is installed under the fixing plate. The fixing plate is detachably installed under the connecting column, and the fixing seat is fixed on the connecting column. The detachable assembly can be detachably installed on the fixing seat.

[0008] Specifically, the detachable component includes a connecting seat, an internal threaded hole is provided on the fixing seat, an external thread is provided on the outer surface of the connecting seat that is threadedly connected to the internal threaded hole, and a fixing groove for mounting the relay body is provided on the top of the connecting seat away from the fixing seat. When the connecting seat is fully threadedly connected to the fixing seat, the connecting seat is at least partially exposed outside the fixing seat.

[0009] Specifically, an internal threaded hole is provided on the fixing plate, and an external thread is provided on the connecting column to be threadedly connected to the internal threaded hole, so that the threaded connection is easy to disassemble.

[0010] Specifically, the cross sections of the fixing seat and the groove are both circular, and the center lines of the circles coincide with each other.

[0011] Specifically, the base includes a support plate and support legs located on both sides of the support plate. The support legs support the support plate so that there is a gap between the surface of the support plate under which the support legs contact, and the fixing plate and rubber pad are located therein. Several connection holes are opened on the support legs.

[0012] Specifically, the rubber pad has a polygonal structure and has anti-slip grooves on the bottom surface.

[0013] The beneficial effects of the utility model are:

[0014] 1. The structure of the utility model is simple. You only need to fix the connecting base to the bottom surface of the relay body first. The relay body can be connected to the fixing base through the threaded connection between the connecting base and the fixing base. Then, the base of all relay bodies can be detachably installed, so that one or several relay bodies can be easily disassembled.

[0015] 2. The relay body can also adjust the angle of the circumferential position. By rotating the connecting column with external force, the angle of the relay body can be adjusted to correspond to the position of the pins on the circuit board, which is flexible to use.

[0025] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] This embodiment provides an expandable combined relay, comprising a relay body 10 and a mounting frame 20 for mounting a plurality of relay bodies 10. The relay bodies 10 are mounted to corresponding positions of a circuit board or electronic components via the mounting frame 20. The mounting frame 20 includes a base 21, a plurality of rotating assemblies 22, and detachable assemblies 23, wherein one detachable assembly 23 corresponds to each rotating assembly 22, and the detachable assemblies 23 are connected one to one.

[0027] The relay body 10 is mounted on the rotating assembly 22 via a detachable assembly 23 for easy disassembly. The rotating assembly 22 rotates under external force to facilitate adjustment of the installation angle of the relay body 10.

[0028] The rotating assembly 22 includes a circular groove 221, a connecting column 222, a fixing plate 223, a rubber pad 224, and a fixing seat 225 opened on the base 21. A mounting hole 226 is opened in the center of the groove 221. The connecting column 222 is passed through the mounting hole 226 and can move up and down in the mounting hole 226. A rubber pad 224 is installed under the fixing plate 223. The rubber pad 224 has a polygonal structure and has protrusions around it for easy gripping or friction connection with external objects, and the bottom surface is provided with anti-slip grooves to increase the anti-slip performance.

[0029] The fixing plate 223 can be detachably mounted under the connecting column 222, making it convenient to assemble the connecting column 222 and other components onto the base 21; the fixing plate 223 can block the mounting hole 226 to prevent the connecting column 222 from falling out of the mounting hole 226, and the fixing seat 225 is fixed on the connecting column 222. The connecting column 222 moves downward, which can drive the fixing seat 225 to hide in the groove 221, and the detachable component 23 can be detachably mounted on the fixing seat 225.

[0030] The detachable component 23 includes a connecting base 231, an internal threaded hole 227 is formed on the fixing base 225, and an external thread 228 is provided on the outer surface of the connecting base 231 that is threadedly connected to the internal threaded hole 227. A fixing groove for mounting the relay body 10 is provided on the upper surface of the connecting base 231 away from the fixing base 225. When the connecting base 231 is fully threadedly connected to the fixing base 225, the connecting base 231 is at least partially exposed outside the fixing base 225. The exposed portion is a portion that is easy for people or machines to hold or clamp, thereby facilitating the clamping operation.

[0031] An internal threaded hole is provided on the fixing plate 223, and an external thread is provided on the connecting column 222 for threaded connection with the internal threaded hole 227. The threaded connection is used for easy disassembly.

[0032] The cross sections of the fixing seat 225 and the groove 221 are both circular, and the center lines of the circles coincide with each other, so that the appearances of the two are matched and more beautiful.

[0033] The base 21 includes a support plate 211 and support legs 212 located on both sides of the support plate 211. The support legs 212 support the support plate 211 so that there is a gap between the surface of the support plate 211 below that contacts the support legs 212, leaving space for the fixing plate 223 and the rubber pad 224 to be located therein. A number of connecting holes 213 are provided on the support legs 212, and screws are inserted into the connecting holes 213 to fix the support legs 212 to the circuit board.

[0034] When the utility model product is used:

[0035] First, connect the fixing base and the connecting column, then the rubber pad under the connecting column abuts against the outer surface of the circuit board. The connecting base is fixed to the lower end of the relay body by adhesive and partially wrapped around the outside of the relay body. The connecting base is threadedly connected to the fixing base to fix the relay body on the base. The base is fixed to the circuit by screws. Since the rubber pad abuts against the outer surface of the circuit board, the relay body is difficult to rotate without external force. When the angular position of the relay body needs to be adjusted, the relay body can be held and rotated by human or mechanical force; outside the relay body, the connecting base is threadedly connected to the fixing base to facilitate disassembly.

[0036] Based on the above-mentioned ideal embodiments of this application, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the scope of the technical concept of this application. The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
