Description

Technical Field

[0001] The utility model relates to the technical field of insulating terminals, and particularly relates to an insulating terminal structure for a relay. Background Art

[0002] A relay is an electrical control device that is widely used in household appliances, remote control, communication, and automation control circuits. Its essential function is an automatic switch that controls the large current in the output circuit by controlling the small current in the control circuit. However, after the relay is installed, an insulating terminal is still required. An insulating terminal is a piece of metal enclosed in insulating plastic, with holes at both ends for inserting wires and screws for tightening or loosening. For example, for two wires, sometimes they need to be connected and sometimes disconnected. At this time, the terminals can be used to connect them and can be disconnected at any time without having to weld or wind them together, which is very convenient and fast.

[0003] Most of the existing insulating terminals fasten or loosen the wires through screws, but relying solely on screws for fixation is relatively single. When the wires are inside the insulating terminal, especially when pulled by an external force, the wires are still prone to shaking. In addition, the replacement of the connection head and the insulating sleeve on the insulating terminal is also relatively inconvenient. Especially when one of the components is damaged, the entire insulating terminal is often replaced. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an insulating terminal structure for a relay, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An insulating terminal structure for a relay includes an insulating sleeve. A first connection sleeve is installed at the left end of the insulating sleeve, a second connection sleeve is installed at the right end of the insulating sleeve, a fixing screw is installed at the upper right part of the second connection sleeve, a connection device is installed at the right end of the second connection sleeve, and a clamping device is installed in the middle of the upper end of the insulating sleeve.

[0007] Preferably, the connection device includes a connection head. A connection sleeve is fixedly installed at the left end of the connection head. A screw hole is opened at the upper right part of the connection sleeve, and external threads are engraved on the left part of the outer surface of the connection sleeve. The connection head is threadedly installed at the right end of the second connection sleeve through the connection sleeve. The connection sleeve is threadedly connected to the second connection sleeve, and a fixing screw is also provided on the second connection sleeve. After the connection sleeve is threadedly installed, it is fixed by the screw. The double fixing method avoids the loosening of the connection head and ensures the stability of the connection head. Moreover, the surface of the connection head has a nickel plus matte tin coating, thereby improving its electrical conductivity and welding performance.

[0008] Preferably, the clamping device includes a rotating block, a threaded rod is fixedly installed at the lower end of the rotating block, a threaded groove is opened in the middle of the upper end of the insulating sleeve, the rotating block is installed in the middle of the upper end of the insulating sleeve through the threaded rod, and internal threads are engraved on the inner wall of the second connecting sleeve. By rotating the rotating block, the rotating block drives the threaded rod at its lower end to press down and clamp the wire of the relay in the insulating sleeve. At the same time, several anti-slip bumps in the first connecting sleeve can also clamp the wire of the relay, thereby improving the stability of the wire of the relay after insertion.

[0009] Preferably, several anti-slip bumps are fixedly installed in the first connecting sleeve.

[0010] Preferably, after the connecting sleeve is screwed into the second connecting sleeve, the positions of the fixing screw and the screw hole correspond up and down.

[0011] Preferably, several of the anti-slip bumps are distributed in a circular array in the first connecting sleeve.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When the relay needs to use an insulating terminal to connect with the wire of an electrical product, first insert the connector on the connecting device into the terminal of the electrical product, and then insert the wire of the relay into the connecting sleeve through the first connecting sleeve, the insulating sleeve and the second connecting sleeve, so that the wire of the relay is connected to the corresponding wire of the electrical product through the connector. At the same time, after the wire of the relay is inserted, by rotating the rotating block on the clamping device, the rotating block drives the threaded rod at its lower end to press down and clamp the wire of the relay in the insulating sleeve. At the same time, several anti-slip bumps in the first connecting sleeve can also clamp the wire of the relay, thereby improving the stability of the wire of the relay after insertion. Moreover, the surface of the connector has a nickel plus matte tin coating, thereby improving its electrical conductivity and welding performance.

[0014] 2. The connecting sleeve is threadedly connected to the second connecting sleeve, and a fixing screw is also provided on the second connecting sleeve. After the connecting sleeve is threadedly installed, it is fixed by the screw. The double fixing method avoids the loosening of the connector and ensures the stability of the connector. At the same time, the whole device can also be disassembled. That is, when the insulating sleeve or the connector is damaged, the threaded rod is screwed out of the insulating sleeve, and then the fixing screw is loosened and the connector is screwed out, so as to replace a damaged part of the insulating terminal.

The connecting head 20 is threadedly installed at the right end of the second connecting sleeve 5 through the connecting sleeve 21. After the connecting sleeve 21 is screwed into the second connecting sleeve 5, the positions of the fixing screw 6 and the screw hole 23 are vertically corresponding. The connecting sleeve 21 is threadedly connected in the second connecting sleeve 5, and a fixing screw 6 is also provided on the second connecting sleeve 5. After the connecting sleeve 21 is threadedly installed, it is fixed by the screw. The double fixing method avoids the loosening of the connecting head 20 and ensures the stability of the connecting head 20. Moreover, the surface of the connecting head 20 has a nickel plus matte tin coating, thereby improving its electrical conductivity and welding performance.

[0025] The clamping device 3 includes a rotating block 30. A threaded rod 31 is fixedly installed at the lower end of the rotating block 30.
