Abstract
The utility model discloses a seven-core high-voltage electric connector, comprising a plug and a socket. The plug is formed by a plug housing, a tail housing, and contact pins. The socket is formed by a socket body, jacks, and crown reeds. An outer surface of the plug housing is provided with a positioning milling flat plane. An inner wall is provided with a positioning milling flat plane. An inner cavity is provided with an arc-shaped barrier, a raised rib, and contact pin holes. An outer surface of an end of the socket body is provided with a positioning milling flat plane, the middle part is provided with an arc-shaped concave pit, a side surface is provided with a square concave pit, and an end face is provided with jack holes. The contact pins and the jacks are in a barb structure. The tail end of the socket body is a welding cup. The electric connector is characterized by high-voltage resistance, simple and compact structure, light weight, low manufacturing cost, etc. The electric connector can be plugged in a blind manner, and has certain retention force after butt joint, thereby ensuring good butt joint performance. The electric connector can disconnect from a butt joint position under relatively large tension forces. The electric connector has high security, and is especially suitable for medical industry.
Description
Technical field
The utility model relates to technical field of electric connectors, especially a kind of seven core high-voltage electric connectors.
Background technology
The modes such as the connected mode of electric connector is threaded, kayser connection, plug-type connection, existing connected mode all can guarantee not disconnect under larger pulling force, realize reliable connection, but just there is certain defect for mobile platform, particularity due to mobile platform, especially for the high-tension connector using on mobile platform, need higher fail safe, can blindmate, can prevent high pressure electric leakage, for the demand of mobile platform high-tension connector, design a high security, miniature connector high voltage withstanding, anti-mis-insertion seems very necessary.
Utility model content
The purpose of this utility model is a kind of seven core high-tension connectors that provide for the characteristic of mobile platform, and it has, and volume is little, reliability is high, possesses blindmate characteristic, is applicable to little space, mobile platform, proof voltage lower than the application scenario of 4000V.
The concrete technical scheme that realizes the utility model object is:
A kind of seven core high-voltage electric connectors, feature is that it is comprised of plug and socket, described plug comprises plug body, contact pin and afterbody shell, plug body is cylindric, its outer surface is provided with that location milling flat horizontal surface, inwall are provided with location milling flat horizontal surface, inner chamber is provided with circular-arc jube, convex tendon and pin holes, and contact pin is that hangnail structure, tail end are weldering cup, and afterbody shell is cylindric, described contact pin is plugged in the pin holes of plug body, afterbody shell and plug body interference fit plastic packaging; Socket comprises socket, the jack spring of coming of age, socket one end is that cylinder, one end are that cylindric, middle part has fixed head, its cylinder end outer surface is provided with location milling flat horizontal surface, middle part and is provided with that circular-arc pit, side are provided with square pit, end face is provided with jack hole, cylindric end fixed head place is provided with location and installation boss, described jack is hangnail structure, tail end, for weldering cup, is located in the jack hole on socket, and hat spring is loaded on jack front end; Contact pin on plug body docks with the jack on socket.
The contact that the utility model is comprised of contact pin and jack is fixed in connector by hangnail structure, the blindmate of connector is realized by location milling flat horizontal surface and the circular-arc jube of plug and socket, the rotation of plug convex tendon restriction socket, in plug body, circular-arc jube increases creepage distance, realizes electric signal transmission.
The utility model is considered from the use function of connector, meets the blindmate characteristic of connector, guarantees the fail safe of connector when the transferring high voltage signal of telecommunication.The utility model difference with the prior art is:
, adopt circular-arc jube to increase creepage distance, meet high pressure resistant requirement.
(2), adopt milling flat horizontal surface and circular-arc jube etc. to realize the blindmate of connector.
(3), contact connect to adopt contact pin to coordinate with hat spring the contact engaging and separating force that keeps certain, guarantees reliably connection.
