Abstract

An electric appliance connector comprises a shell made of an insulating material and wiring terminals made of metal materials. The above shell is equipped with jacks molded along a length direction, a circular ring is radially protruded on the inner wall of each jack, and a stepped surface is formed between the front end of the circular ring and the inner wall of the jack. Each wiring terminal is equipped with fastening pins, and the back end of each wiring terminal is connected with a conducting wire; the front ends of the wiring terminals are inserted in the jacks of the shell, and the fastening pins are buckled on the stepped surfaces to fix the wiring terminals on the shell. A fastening block is protruded radially at the back end of each wiring terminal, and the back end of the shell is equipped with a locking and buckling member. The locking and buckling member is equipped with through holes through which the conducting wires can pass, and the through holes can limit the above fastening blocks in the jacks of the shell. Compared with the prior art, the advantage of the utility model is that: the locking and buckling member is arranged at the back end of the shell additionally, so that the locking and buckling member and the fastening blocks of the wiring terminals are in secondary locking to isolate the loosening paths of the wiring terminals, and accordingly, the loosening problem of the connector can be solved effectively.

Description

Electrical connector

Technical field

The utility model relates to a kind of electrical connector, relates in particular to the connector on a kind of electric equipment products, belongs to wire interconnection technique field.

Background technology

Existing electrical connector, generally comprise the housing of insulation material and the binding post (claiming again contact pin or slot) of metal material, housing alongst forms jack, this jack inwall radial convex be provided with annulus and and form step surface between the jack inwall, binding post has card base, the rear end of this binding post is connected with wire, and front end is inserted in the jack of housing, and card base is buckled on step surface and binding post is fixed on housing surely and can not throw off.

In the connector production process of reality, because the cooperation of part binding post is not in place, easily occur the phenomenon that gets loose after inserting.Find by the statistical analysis of inefficacy product, at present, it is not in place that the main cause that gets loose of connector is that connector patches, and stressed rear contact pin ejects and causes.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of binding post to coordinate the electrical connector that puts in place and be difficult for getting loose for the above-mentioned state of the art.

the utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of electrical connector, comprise the insulate housing of material and the binding post of metal material, aforesaid housing alongst forms jack, this jack inwall radial convex is provided with annulus, form step surface between this annulus front end and jack inwall, aforesaid binding post has card base, this binding post rear end is connected with wire, front end is inserted in the jack of housing, aforesaid card base is buckled on step surface and makes binding post surely be fixed on housing, it is characterized in that: the rear end radial protrusion of described binding post has fixture block, the rear end of described housing is provided with a snap close piece, this snap close piece has the through hole that passes through for wire, and, this through hole can be limited in aforesaid fixture block in the jack of housing.

Described binding post encases wire by riveting sheet, and the radial protrusion of described riveting sheet forms described fixture block.The expansion characteristics of riveted joint position are come to form fixture block along band, are beneficial to the manufacturing.

Easy to assembly for making, connect closely, described snap close piece comprises the vertical portion and is raised in the sleeve part of vertical portion, and this sleeve part stretches in the jack of housing and has the central passage of passing through for wire, and described fixture block is limited in the sleeve part front end face.Further, the jack of described sleeve part and housing is tight fit.Be connected firmly.

As preferably, the connected mode of snap close piece and housing is preferably as follows setting: the top of described vertical portion forms grab, and accordingly, the rear end outer wall of described housing is raised with for the adaptive projection of aforementioned grab.Certainly can also realize being connected and fixed with setting-in or concave-convex fit structure.

Compared with prior art, the utility model has the advantage of: set up snap close piece in the housing rear end, make between the fixture block of snap close piece and binding post and form secondary locking, the approach that pair of wire connection terminals gets loose completely cuts off, and can effectively solve this connector problem that gets loose.

Embodiment

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.

as Fig. 1, Fig. 2 and shown in Figure 3, electrical connector in the present embodiment comprises the housing 1 of the material that insulate, the binding post 2 of metal material and snap close piece 3, housing 1 alongst forms a plurality of jacks 11, each jack 11 inwall radial convex is provided with annulus 13, form step surface 14 between these annulus 13 front ends and jack 11 inwalls, binding post 2 has card base 21, binding post 2 rear ends are connected with wire 4, front end is inserted in the jack 11 of housing, card base 21 is buckled on step surface 14 and binding post 2 is fixed on housing 1 surely, the rear end radial protrusion of binding post 2 has fixture block 22, snap close piece 3 is located at the rear end of housing 1, this snap close piece 3 has the through hole that passes through for wire, and, this through hole can be limited in fixture block 22 in the jack 11 of housing.

Particularly: binding post 2 encases wire by riveting sheet 23, and the radial protrusion of riveting sheet 23 forms fixture block 22.Snap close piece 3 comprises vertical portion 31 and is raised in the sleeve part 32 of vertical portion 31, and this sleeve part 32 stretches in the jack 11 of housing and has the central passage of passing through for wire 4, and sleeve part 32 is tight fit with the jack 11 of housing.Fixture block 22 is limited in sleeve part 32 front end faces.The top of vertical portion 31 forms grab 33, and accordingly, the rear end outer wall of housing 1 is raised with for the adaptive projection 12 of grab.

It is expendable locked that card base 21 and step surface 14 form, and fixture block 22 forms secondary lockings with sleeve part 32, and double locking can effectively solve this connector problem that gets loose.It is larger that the fastening of housing 1 and snap close piece 3 can bear external force, can resist more greatly inserting power, can guarantee the contact pin slot when inserting, accurate positioning.In wire and binding post riveted joint process, rivet the expansion characteristics of position and come to form fixture block along band, be beneficial to the manufacturing.
