Handle-type high-voltage connector

Abstract

The invention discloses a handle anti-loosening mechanism, which is easy to operate, long in service life and reliable in secondary locking, and a handle-type high-voltage connector using the handle anti-loosening mechanism. The handle anti-loosening mechanism comprises a main body slide groove arranged on a high-voltage connector main body in an integrated manner; a locking block detachably and slidably arranged in the main body slide groove to limit or allow a handle of the high-voltage connector to rotate with respect to the high-voltage connector main body; and a locking press block detachably arranged on a connecting rod portion of the handle, wherein the locking block has a buckle position for buckling with the main body slide groove, and the locking press block has an abutting portion abutted against the buckle position to allow the locking block to slide in the main body slide groove.

Description

technical field [0001] The present invention relates to a handle-type high-voltage connector for connecting high-voltage cables, and more specifically to a handle-type high-voltage connector with a handle-type high-voltage connector and a handle-type high-voltage connector with the handle-type high-voltage connector. Background technique [0002] In recent years, significant progress has been made in high-voltage connector technology. For example, in eco-friendly vehicles such as hybrid vehicles and electric vehicles, high-voltage connectors for connecting high-voltage cables are widely used. In order to make the two connector parts (male side connector part and female side connector part) of the high voltage plug and the high voltage socket easy to lock and separate so that they are in the mated state and the non-fitted state, in the high voltage connector A handle part is often added, and such a high-voltage connector is called a handle-type high-voltage connector.

AI Technical Summary

Problems solved by technology

However, in the case of high-voltage connections, the size and weight of the high-voltage plug and high-voltage socket itself are relatively large, so the handle mechanism requires a large external force to rotate to achieve the locking and separation of the high-voltage connector

However, since the space at the handle connecting rod is very limited, as disclosed in the above-mentioned prior art, the secondary locking mechanism of the handle with a buckle / slot structure and its ejection device are adopted, so the operator is very laborious and laborious to operate. inconvenient to use

In addition, the buckle / slot structure is also prone to engagement failure due to vibration, etc. Although the ejection device is further provided in the above-mentioned prior art, in the actual working environment of the high-voltage connector, the ejection device It is also easy to loosen due to vibration etc.

Not only that, such a buckle / slot structure is difficult to withstand excessive external force due to the relatively concentrated force, so when the operator exerts too much force, it may also cause other safety hazards due to the sudden damage or separation of the buckle and the slot. Hidden danger

In addition, if the buckle / slot structure is often scrapped due to excessive external force during use, it is necessary to frequently replace the handle or some components of the advanced connector

Furthermore, since the chute and the slide block of the ejection device are also relatively thin in structure, they are easily broken or damaged during frequent use, resulting in the scrapping of the entire handle and high maintenance costs
