Abstract

The utility model provides a connector receptacle, including a shell body, an internal base body, electric contact points and wires, wherein the shell body is a seamless canister type shell body molded by insulation material, the internal base body includes a pair of extended parts, a clamping slot is arranged at the front end of the each extended part, the wires pass through the internal base body and are welded with the electric contact points at the tail ends, the two electric contact points are just inserted into the two clamping slots to make the wires and their two electric contact points clamped and positioned by the internal base body; the internal base body is placed into the hollow inside of the shell body from the backside, and then the thermoplastic padding is filled into the end space of the shell body. The connector receptacle uses the internal base body to clamp and fix the electric contact points and the wires, to enhance the intensity of the whole connector structure, to make the connector receptacle suitable for heavy-current and hot environment, with no need for adhesives or an ultrasonic mode to bond subassemblies.

Description

Connector body

One, technical field

The utility model relates to electric connector, relates in particular to a kind of Socket casing inside and grips electric terminal and lead by inner base frame, and temperature tolerance is good, flexible type not, is suitable for the connector body that big electric current and hot environment are used.

Two, background technology

Connector is widely used in various places, for example uses battery as the electronic toy of power etc.Existing connector, many distinct disadvantage when using, reality are arranged and practicality no all roses, modal puzzlement is that the electric terminal contact site of plug and socket because big electric current is flowed through can generate high heat and conduct to plug and socket at electric terminal in operation; Because existing plug and socket are by adhesive or the ultrasonic wave mode structure that shell is bonding, be subject to temperatures involved and make bond site generation qualitative change, will cause gap and slight crack after using when long, especially plug and socket are pegged graft or pull out when separating as the end user, because above-mentioned high heat, a little firmly situation that the shell body modification will take place and break.During manufacturing, existing connector is limited by base and last cover combined structure, and essential lead by complexity makes up preparation process such as processing and the bonding loam cake processing of ultrasonic wave, makes to make comparatively to bother and takes a lot of trouble, and can't reduce cost; In addition, the finished product of making more has on plug and the socket to demonstrate the joint clearance, has the shortcoming of appearance tactile impression difference.

Three, utility model content

Main purpose of the present utility model is to overcome the above-mentioned shortcoming that existing product exists, and provide a kind of connector body, it is in Socket casing inside, grip electric terminal and lead by inner base frame, make this connector body have good, the not flexible type, and the advantage that is suitable for big electric current and hot environment use of temperature tolerance.

Another purpose of the present utility model is to provide a kind of connector body, its integrated seamless cartridge type housing, cooperate the inner base frame that grips electric terminal and lead, make the designs simplification of plug and socket, do not need complicated assembling processing, make manufacturing process more simple, spare part reduces, and is cheap and useful life is better.

The purpose of this utility model is realized by following technical scheme.

The utility model connector body comprises housing; It is characterized in that described housing is the integrated seamless cartridge type body of insulating material; The hollow inside of housing is provided with inner base frame, and this inner base frame is that insulating material is made, and it comprises a pair of extension, and each extension is provided with clip slot foremost; Lead passes through line hole default on the inner base frame, and in end welding electric terminal; Two electric terminals are embedded in two clip slots of inner base frame extension, and lead and terminal two electric terminals are located by the inner base frame clamping; Inner base frame is inserted housing hollow inside from the housing rear, the plastic filler of filling heat and form one in the shell end space again, thus constitute connector body.

Aforesaid connector body, wherein the filling of hot plastic filler is to utilize socket die automation filling processing, can optionally the socket end be made different shapes according to mold shape.

The beneficial effect of the utility model connector body is to comprise housing, inner base frame, a pair of electric terminal and lead; Housing is the integrated seamless cartridge type housing of insulating material; Inner base frame is that insulating material is made, and comprises a pair of extension, and each extension front end is established clip slot, and inner base frame can be placed into enclosure interior; Lead can pass through line hole default on the inner base frame, and in end welding electric terminal; Two electric terminals can be embedded in two clip slots of inner base frame extension, and lead and terminal two electric terminals are located by the inner base frame clamping.Inner base frame is inserted the hollow inside of housing from the housing rear, form one at the shell end space filling plastic filler of heat again, promptly constitute connector body of the present utility model.This connector body need not use adhesive or ultrasonic wave mode bonded assemblies, is to utilize inner base frame to grip electric terminal and lead, has strengthened the structural strength of connector body integral body, makes connector body be applicable to big electric current and hot environment.The connector body that the utility model provides, its integrated seamless cartridge type housing, cooperate the inner base frame that grips electric terminal and lead, make the designs simplification of plug and socket, do not need complicated assembling processing, make manufacturing process more simple, spare part reduces, and is cheap and useful life is better.
