technical field

The utility model relates to a connector, in particular to a post-mounted switch controller anti-open-circuit circular connector which is more reliable and automatically conducts after the plug is separated from the socket.

Background technique

Existing connectors are mainly used for circuit connection between electric equipment and various electronic instruments and electrical equipment. Because it is often used in harsh environments such as floods and sewage, the requirements for the sealing, waterproof and pressure resistance of the connector are very high.

However, during the use of the existing connector, when the plug and the socket are disconnected under normal conditions, the contacts in the plug show an unstable automatic conduction state, and the connected system cannot be reliably short-circuited and grounded. the

Further speaking: the front end of the jack sheath is provided with a fixed piece and a small compression spring.

A rubber pad is provided at the part where the convex body is combined with the electrical equipment.

An o-ring is provided at the joint between the transition cover and the connecting cap.

A flat washer is arranged between the locking cap and the sealing sleeve.

Due to the adoption of the above technical solution, compared with the prior art, the utility model has high working stability. When the plug and the socket are disconnected under normal conditions, the contacts in all the plugs are more automatically turned on, which can strengthen the power system. and equipment security. In addition, the utility model has a simple structure, is easy to produce, has excellent sealing performance, waterproof performance and pressure resistance, and can be applied to relatively harsh working environments such as coal mines and floods.

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

Detailed ways

Example:

An anti-open circuit circular connector for a switch controller on a column includes a plug and a socket, and the plug is connected to the socket in a sealed manner.

As shown in Figure 1, the plug includes a connection cap (109), a transition cover (111), a sealing sleeve (118), a flat washer (117), a clamping plate (113), and a clamping plate type locking cap (116) , jack insulator (123) and some jacks (101); Connection cap (109) <inner end bottom is placed with corrugated spring (108)> is enclosed within the periphery of the front end of transition cover (111); Jack insulator (123) Installed in the inner cavity of the front part of the transition cover (111), the end of the jack insulator (123) is installed with a jack cover (119), and the front side of the jack cover (119) has a compression spring (107) and a jack The sheath (120), the front end of the clip spring (107) has a short circuit (103); the sealing sleeve (118) is located in the inner chamber at the end of the transition cover (111), and the flat washer (117) and the clamping plate type locking cap ( 116) is located at the rear side of the seal sleeve (118), and the splint type locking cap (116) is screwed into the afterbody cavity of the transition cover (111).

The structural feature of the above-mentioned post-mounted switch controller anti-open circuit circular connector is that a fixed piece (121) and a small compression spring (122) are added to the front end of the jack sheath (120), and when the plug is not connected to the socket , because the small compression spring 122 presses the fixed piece 121 to the short-circuit piece 103, and the compression spring 107 presses the short-circuit piece 103 to the fixed piece 121, so that the contacts are more reliable and all conduction (short circuit), and the stability of the power system is enhanced.
