Abstract
The utility model relates to a plug-in electrical connector. The electrical connector comprises a plug and a socket, wherein, the plug comprises a plug housing; a plug contact element is arranged in the plug housing; the socket comprises a socket housing; a socket contact element is arranged in the socket housing; an elastic cantilever extends forwards at the front end of the plug housing; a barb raised outwards is arranged at the overhanging tail end of the elastic cantilever; a matched insertion cavity, in which the front end of the plug is inserted, is formed at the front part of the socket housing; a clamping groove penetrating the cavity wall of the matched insertion cavity is formed on the cavity wall of the matched insertion cavity; and the clamping groove and the barb are clamped with each other correspondingly in a matched manner. A connector adopting the structure can solve the problem of circuit system breakdown caused when a non-operator unplugs the connector improperly.
Description
Technical field
The utility model relates to a kind of grafting electric connector.
Background technology
At present, at field of connectors plug and fixing dual modes that adopt after socket is connected, a kind of is to adopt the attaching nut that plug and socket are fixed together more; Another kind of mode is to plug together the back by the contact engaging and separating force between plug casing and Socket casing and plug contact and the socket contact at plug and socket, makes plug and socket keep the state that is connected.The connector that adopts above-mentioned dual mode to connect does not all need to adopt special instrument plug can be separated with socket when plug unplugs with socket.This just exists certain problem, and when connector was in the environment of an exposure, the inoperative personnel also can unplug plug and plug-in mounting under not by the situation of any instrument very easily.Above-mentioned situation can produce beyond thought fault to the entire circuit system.
The utility model content
The purpose of this utility model provides a kind of grafting electric connector, does not use extracting tool also can easily plug and socket be unpluged in order to solve existing connectors, and causes occurring the improper problem that connector produces the Circuits System fault that unplugs.
For achieving the above object, the utility model adopts following technical scheme: a kind of grafting electric connector, comprise plug and socket, and described plug comprises plug casing, is provided with the plug contact in this plug casing; Described socket comprises Socket casing, is provided with the socket contact in this Socket casing, and the front end of described plug casing is extended with elastic cantilever forward, and the end that overhangs of described elastic cantilever is provided with the hangnail to outer lug; The front portion of described Socket casing is provided with the inserting chamber of inserting for plug head, and the chamber wall in described inserting chamber is provided with the draw-in groove that connects this chamber wall, and the corresponding card with hangnail of described draw-in groove ends cooperation.
Described elastic cantilever integrated setting is on the front end face of plug casing.
Described plug casing upper edge circumferentially at least evenly is provided with two elastic cantilevers.
Grafting electric connector of the present utility model, the front end of its plug casing are provided with the elastic cantilever that extends forward, are provided with the hangnail of evagination at the end that overhangs of elastic cantilever.Simultaneously, the chamber wall in Socket casing front end grafting chamber is provided with the draw-in groove that connects this chamber wall.When plug and socket plugged together, elastic cantilever extend in the grafting chamber of Socket casing, and hangnail is limited in the draw-in groove, just plug and socket can't be unpluged under not by the situation of instrument like this.When needs unplug plug and socket, only need to adopt a special instrument to extend in the draw-in groove elastic cantilever is inwardly pressed from the outside, be separated up to hangnail and draw-in groove, after hangnail and exact separation, can very easily plug and socket be unpluged.Obviously, adopt the connector of said structure to avoid unpluging the problem that connector causes the Circuits System fault because of the not operation personnel are improper.
Description of drawings
Fig. 1 is the structural representation of plug in the utility model;
Fig. 2 is the structural representation of socket in the utility model.
Embodiment
Shown in Fig. 1,2, grafting electric connector of the present utility model comprises plug and socket.Described plug comprises plug casing 3, and forward integration is extended with elastic cantilever 4 on the front end face of plug casing 3, and the end that overhangs of elastic cantilever 4 is provided with the hangnail 5 of evagination.Be provided with the stepped cavity before and after connecting in the plug casing 3, the middle part path section of this stepped cavity is a plug contact installing hole, plug-in mounting plug contact 6 in this plug contact installing hole, have ring platform and annular groove on the plug contact 6, the rear end of the plug contact installing hole claw 7 that extended back, holding in end clamping and the annular groove of claw 7, described ring platform cooperates with the end face pushing tow at contact installing hole other end place.The rear end of plug casing stepped cavity is fitted with a cushion rubber 1, and the rear end of plug casing 3 is bolted with a nut 2.Described socket comprises Socket casing 10, has the stepped cavity before and after connecting in the Socket casing 10, the inserting chamber of the front end of this cavity for pegging graft for plug, the chamber wall in this inserting chamber are provided with and the overhang draw-in groove 11 of terminal hangnail corresponding matching of elastic cantilever 4, and this draw-in groove 11 connects the chamber wall in inserting chambeies.The middle part of described Socket casing 10 internal cavities is a socket contact installing hole, be fitted with socket contact 13 in the socket contact installing hole, socket contact 13 is provided with the ring platform, the ring decometer that is provided with on the claw 12 that extended back in the rear end of socket contact installing hole, this claw 12 and socket contact 13 is held and is cooperated.The rear end of stepped cavity is fitted with cushion rubber 8 in the described Socket casing, and the rear end of Socket casing 10 is bolted with a nut 9.
