Special universal interface used for electric power control cabinet and with reliable inserting and connecting

Abstract

The invention discloses a special universal interface used for an electric power control cabinet and with reliable inserting and connecting. The special universal interface comprises a plug and a socket; the plug and the socket are matched in an inserting manner; the plug comprises an upper shell, a contact pin and an upper locking mechanism; a first groove and a third groove are formed in the endplane of the upper shell; the contact pin is fixedly connected in the first groove; a second groove connected with the third groove is formed in the side surface of the upper shell; an elastic section of the upper locking mechanism is fixedly connected with the bottom surface of the second groove; a locking section of the upper locking mechanism is glidingly matched with the second groove; the socket comprises a lower shell, an inserting sleeve and a fixed column; the fixed column is fixedly connected with a base shell, and glidingly matched with the third groove; the fixed column is tightlyclamped and matched with the locking section of the upper locking mechanism; a fourth groove corresponding to the contact pin is formed in the lower shell; and the inserting sleeve is fixedly connected in the fourth groove and glidingly tightened and matched with the contact pin. In all, the special universal interface is convenient to mount and detach, high in stability, and capable of unifying switch cabinet relay protection apparatuses of different wiring modes, thereby achieving a time-saving, labor-saving, convenient and efficient effect.

Description

technical field [0001] The invention relates to the electrical field, in particular to a universal interface for reliable plugging and connection of a power control cabinet. Background technique [0002] At present, the replacement of relay protection devices in switch cabinets has been carried out on a regular basis. However, with a product span of more than ten years, even if the original products of the same manufacturer are used, the consistency of the terminal wiring of the product cannot be guaranteed. , these tasks are not only a huge workload, but the reliability of the secondary circuit is reduced due to the reconnection of the secondary line, and a huge workload such as re-transmission is required. The traditional relay protection device replacement project requires multiple steps every time, and the workload is large. It is time consuming and the work requires high precision. For example, if the wiring between the relay protection equipment and the terminal bloc...

However, with a product span of more than ten years, even if the original products of the same manufacturer are used, the consistency of the terminal wiring of the product cannot be guaranteed. , these tasks are not only a huge workload, but the reliability of the secondary circuit is reduced due to the reconnection of the secondary line, and a huge workload such as re-transmission is required. The traditional relay protection device replacement project requires multiple steps every time, and the workload is large. Time-consuming, and the work requires high precision

For example, if the wiring between the relay protection equipment and the terminal block is mismatched, poor contact, or empty, the wiring problem can only be found in the later stage of debugging, which has a great potential safety hazard

The existing interface is inconvenient to connect, and the stability after plugging is poor, especially in a high-voltage environment such as a substation, if the plugging is not firm, it will affect the performance of the relay protection device, resulting in economic losses and even irreparable power consumption disasters
