General self-locking insulation protective cover cooperated with fast connecting terminal

Abstract

The invention discloses a general self-lock type insulating protection sleeve matched with quick-connection terminals, leading the quick-connection terminals to be easy to be inserted into and unlikely to get out of the protection sleeve. Stop parts for the terminals are arranged at the middle section of the insulating sleeve body of the protection sleeve; stop grooves for the terminals are respectively arranged at the front and the back sides of the face part of the stop parts for the terminals, while corresponding stop lug bosses for the terminals are formed at the front and the back sides of the inner wall of the face part of the stop part for the terminals; a terminal cavity is arranged between the stop grooves for the terminals and the entry holes of plugging sheets; a longitudinal guiding convex groove is arranged at the central part of the inner wall of the face part of the terminal cavity; drum-shaped side parts are arranged at both sides of the middle section of the insulating sleeve body of the protection sleeve. The general self-lock type insulating protection sleeve matched with quick-connection terminals is mainly applied to match with the 250 type quick-connection terminals of different specifications.

Description

A kind of universal self-locking insulation protection cover matched with quick-connect terminal technical field The invention relates to terminal protective sleeves, in particular to a universal self-locking insulating protective sleeve matched with quick-connect terminals. Background technique The insulating terminal protective cover is used in conjunction with the connecting wire terminal to provide insulation protection. It is mainly used on the connecting wires of the internal circuit of the electrical appliance. The characteristic of the conventional post-mounted insulated terminal protection sleeve is that the wiring terminal can only enter the sheath cavity after a certain distance from the sheath entrance. Since there is a groove between the sheath entrance and the terminal clamping position, the size is narrowed. When wiring When the terminal passes through, the resistance is relatively large, and it takes a little force to pass through. Therefore, the threading...

Problems solved by technology

The characteristic of the conventional post-mounted insulated terminal protection sleeve is that the wiring terminal can only enter the sheath cavity after a certain distance from the sheath entrance. Since there is a groove between the sheath entrance and the terminal clamping position, the size is narrowed. When wiring When the terminal passes through, the resistance is relatively large, and it takes a little force to pass through. Therefore, this type of sheath has a slow threading speed, which affects production efficiency.

Although the size of this place can be appropriately widened to make it easier for the terminals to pass through, but in this way, the protective sleeve will easily fall off and the terminals will lose their insulation protection.
