Description

Technical Field

[0001] This utility model belongs to the field of automatic control, and specifically relates to a switch lead-out device. Background Technology

[0002] With the widespread adoption of the Internet of Things (IoT), electronic instruments and devices such as remote controls with button functions and smart keys need to be integrated with IoT for intelligent monitoring, management, and control in many situations.

[0003] During automation upgrades, for example, physical buttons on existing equipment can be brought out through parallel virtual switches, and electronic circuits can be used for monitoring and control. This can greatly improve the convenience of monitoring and the implementation of automatic control, and expand the scope of use of the existing equipment.

[0004] In existing technologies, parallel switches use soldered bypass harnesses, requiring specialized tools such as soldering irons. Slight mishandling can easily damage existing equipment, making recovery difficult and inconvenient for non-electronics professionals. This is especially true for some consumer products, which demand highly skilled operators, hindering widespread adoption.

[0005] In the prior art, a switch lead-out device, as disclosed in patent publication number CN216902569U, aims to reduce the operational difficulty of connecting lead-out circuits to switches. The switch lead-out device includes a bracket and a conductive sheet. The bracket is used to fasten onto the switch; the conductive sheet includes a lead-out piece and a contact piece. The conductive sheet is disposed on the bracket, and the lead-out piece is located on the surface of the bracket. The lead-out piece is used to connect to the lead-out circuit, and the contact piece is used to contact the exposed contacts when the bracket is fastened to the switch. When it is necessary to connect a lead-out circuit to the switch to monitor switch operation or control the switch in parallel, the bracket is fastened onto the switch, and simultaneously the contact piece contacts the switch contacts. Electrical connection is achieved by connecting the lead-out circuit to the lead-out piece. The operation is simple, requires no tools or experience, and will not damage existing equipment, making digital transformation and automated testing more convenient and efficient.

[0006] However, the switch contacts and contact plates of the above technical solutions are electrically connected by abutting. Since the end face area of ​​the switch contacts is small and the abutting method uses the elastic force of the contact plates, the electrical connection is prone to poor contact, which affects the normal use of the switch. Utility Model Content

[0007] In order to solve the above-mentioned problems in the prior art, namely the problem that the electrical connection of the switch lead-out device is prone to poor contact, this utility model provides a new switch lead-out device.

[0008] The technical solution of this utility model includes:

[0009] A switch lead-out device includes a switch body (1) and a pair of terminals (2) disposed on the switch body (1), characterized in that: it further includes a pair of elastic wire clamps (5) adapted to the terminals (2), and a clamping device that is fastened and electrically connected to the terminals (2), and the elastic wire clamps (5) are electrically connected to the clamping device.

[0010] As an optional technical solution, the elastic wire clamp (5) is an elastic hollow conductive frame. The hollow conductive frame can deform under the action of external force and press the wire inserted in its cavity.

[0011] As an optional technical solution, the elastic wire clamp (5) is an inverted C-shaped conductive frame made of conductive material with one end open.

[0012] As an optional technical solution, the clamping device includes a mounting seat (3) and a fixing seat (6) placed on both sides of the switch body (1), and the mounting seat (3) and the fixing seat (6) are fastened together by fixing bolts (7).

[0013] As an optional technical solution, the fixing seat (6) is provided with a through hole to accommodate the fixing bolt (7), and the mounting seat (3) is provided with a threaded hole that is compatible with the fixing bolt (7).

[0014] As an optional technical solution, the outer end of the through hole of the fixing seat (6) is provided with a receiving groove (9) for accommodating the bolt head of the fixing bolt (7).

[0015] As an optional technical solution, a bottom conductor plate (4) is fixedly provided on the inner side of the mounting base (3), a pressure conductor plate (8) is fixedly provided on the inner side of the fixing base (6), and the elastic wire clamp (5) is electrically connected to the bottom conductor plate (4).

[0016] As an optional technical solution, the lower conductor plate (8) is provided with a connecting protrusion (10), the protrusion of the connecting protrusion (10) is located between the two terminals (2) and is connected to the bottom conductor plate (4).

[0017] The pressure conductor plate (8) is made of conductive metal.

[0018] The beneficial effects of this utility model are:

[0019] (1) By setting up an elastic wire clamping body, the present invention can deform under the action of the clamping device to firmly clamp the external lead wire, thus avoiding the defects of poor contact caused by point contact of external lead wires and the defects of switch reliability caused by poor contact in the prior art.

[0020] (2) This utility model can also be tightly connected to the terminal block by pressing down the conductor plate, the bottom conductor plate and the connecting protrusion, further improving the good contact of the external guide wire. Attached Figure Description

[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] This utility model provides a switch lead-out device.

[0029] like Figure 1 , Figure 2 As shown, this utility model provides a switch lead-out device, including a switch body 1, with two terminals 2 at the lower part of the switch body 1. The switch lead-out device also includes a clamping device, which includes a mounting base 3 on one side of the switch body 1 and a fixing base 6 on the other side of the switch body 1. A locking bolt 7 passes through the fixing base 6 and is engaged and screwed onto the mounting base 3. The fixing base 6 is locked and fastened by screwing the locking bolt 7 onto the mounting block 3.

[0030] The mounting base 6 has a receiving groove 9, and the screw head of the fixing bolt 7 falls into the receiving groove 9. The receiving groove 9 hides the screw head of the fixing bolt 7, reducing the overall volume.

[0031] The mounting base 3 has a bottom conductor plate 4 on its inner side, and the fixing base 6 has a pressing conductor plate 8 on its inner side. The pressing conductor plate 8 has a connecting protrusion 10 on its inner side. The connecting protrusion 10 is fixedly connected to the pressing conductor plate 8. Its protrusion is located between the terminals 2 and contacts the bottom conductor plate 4, so that the contact surface between the bottom conductor plate 4 and the terminals 2 also forms a passage, further increasing the contact area with the terminals 2 and improving the overall circuit reliability.

[0032] An elastic wire clamp 5 is provided on the outer side of the bottom conductor plate 4. In this embodiment, the elastic wire clamp 5 is an inverted U-shaped metal conductor structure with plasticity and elasticity. The elastic wire clamp 5 can deform under the action of external force and form a tight electrical connection with the external wire inserted therein.

[0033] In use, the switch body 1 is connected via the mounting base 3. The bottom conductor plate 4 mounted on the mounting base 3 contacts the terminal 2, and the clamping device presses the terminal 2 to ensure full contact between the terminal 2 and the bottom conductor plate 4, thereby achieving an electrical connection. Then, the external wire is inserted into the elastic wire holder 5 and clamped with clamping pliers to achieve a quick connection of the external wire without the need for soldering. Since the bottom conductor plate 4 contacts the entire side of the terminal 2, the contact area is large, which reduces resistance and the possibility of poor contact.
