Abstract
The utility model provides an explosion-proof electrical connector, which solves the technical problem that aluminum alloy tubular type sectional material can not be used as a casing directly because a positioning device is arranged on the casing, and a casing mold has to be manufactured separately, thereby greatly increasing the cost of the explosion-proof electrical connector. The utility model is characterized in that protruded ribs and the positioning device of a concave groove are arranged on the socket and the plug, respectively. Two axial protruded ribs are arranged on the surface of the insulation piece of the socket and are uniformly distributed on the circumference, and the concave groove complementary with the protruded ribs is arranged on the insulation piece of the plug in the corresponding position. The explosion-proof electrical connector remarkably saves the production cost.
Description
Technical field
The utility model relates to a kind of explosion-proof electric connector, and it comprises plug and socket.
Background technology
Explosion-proof electrical connection device is mainly used in the abominable hazardous areas of environment such as drilling platforms, oil tanker, harbour, contains in the environment maybe may produce and gathers explosive gas mixture.It is made up of socket, plug, plug be by housing and, insulating part and quil formula contact pin constitute, wherein insulating part and quil formula contact pin constitute plug core, socket is to be made of housing, insulating part and the pin holes that matches with quil formula contact pin, wherein insulating part and pin holes constitute the socket core, and said housing is a tube and pipe of aluminium alloy.For making all quil formula contact pins insert separately pin holes simultaneously, on the housing of plug casing and socket, be provided with positioner, specifically be that more than one axial protrusion muscle is set on the surface of plug casing, on the relevant position of Socket casing, be provided with and protrude the Baltimore groove that muscle compensates mutually, can prevent that plug and socket from producing relative displacement vertically, guarantee that quil formula contact pin can insert pin holes separately simultaneously.Because positioner is arranged on the housing, can not directly use the aluminum alloy round pipe profile as housing, must make housing mould separately, has promoted the cost of explosion-proof electric connector so greatly.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model is to provide a kind of explosion-proof electric connector.
The purpose of this utility model is achieved in that it is made up of socket, plug, it is characterized in that: the positioner that protrudes muscle, Baltimore groove is set respectively on socket and plug.
This positioner can be arranged on the insulating part of the insulating part of plug and socket.So, utilize the chance of insulating part die sinking, be located structural design on insulating part, housing directly uses the aluminum alloy round pipe profile, has saved housing mould.
This positioner also can be, make separately and protrude muscle, Baltimore groove, they are adhered to respectively on plug casing and the Socket casing, owing to protrusion muscle, Baltimore groove are plastic materials, it is cheaply more many than making the Al alloy shell mould to make such mould, has saved die cost.
The utility model compared with prior art, its technique effect is: saved explosion-proof electric connector production cost greatly.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Embodiment one
It is made up of plug 1 and socket 2, and plug 1 is made up of plug casing 12, plug insulating part 11 and contact pin 13, and wherein plug insulating part 11 and contact pin 13 are one; Socket 2 is made up of Socket casing 22, socket insulating part 21 and pin holes 23, and wherein socket insulating part 21 and pin holes 23 are one.Positioner is arranged on the insulating part of the insulating part of plug and socket, be provided with two on the surface of socket insulating part 21 and axially protrude muscle 24, these two protrude muscle and are evenly distributed on the socket insulating part circumference Baltimore groove 14 that setting and protrusion muscle compensate mutually on the relevant position of plug insulating part 11.
Protrude muscle and also can be arranged on the plug insulating part, quantity is one or more, can be evenly distributed on the circumference when above when being one, also can be the uneven distribution state.
Embodiment two
Positioner also can be that muscle, Baltimore groove are protruded in making separately, and they are adhered to respectively on plug casing and the Socket casing.Obviously its cost is higher than embodiment one.
Claims (2)
1, a kind of explosion-proof electric connector, it is made up of socket, plug, it is characterized in that: the positioner that protrudes muscle, Baltimore groove is set respectively on socket and plug.
2, according to the described explosion-proof electric connector of claim 1, it is characterized in that: said positioner is to be provided with two axially to protrude muscle on the surface of socket insulating part, these two protrude muscle and are evenly distributed on the socket insulating part circumference Baltimore groove that setting and protrusion muscle compensate mutually on the relevant position of plug insulating part.
