Wire harness one end is fixedly connected by solder joint 1 with electrical connector plug, is drawn through the through hole on housing 3.In order to avoid wirning harness
Butt welding point 1 applies active force when being acted on by external force, reduces the damage of butt welding point 1, and wirning harness is clamped by individual pressing plate 2.Described
Pressing plate 2 is fixed on housing 3, exposes to the outside of housing, this structure design, is caused the thickness of plug larger, is unfavorable for electricity
The bending of wire harness.
The content of the invention
Present invention solves the technical problem that it is：There is provided a kind of structural thickness small electrical connector plug.
The technical scheme is that：A kind of electrical connector plug, it is characterized in that：Described plug includes the He of shell body 4
Middle casing 5, shell body 4 and middle casing 5 have the structure inside and outside insertion housing, the He of shell body 4 in corresponding position
The inside and outside outlet hole 6 of connection electrical connector plug, the external electricity of electrical connector plug are formed after the installation of middle casing 5 is fixed
Wire harness is drawn by outlet hole 6.
Preferably, annular knurl is machined with the face that outlet hole 6 contacts with external cord beam.
Preferably, the cross-sectional area of outlet hole 6 is less than the cross-sectional area of external cord beam.
Preferably, shell body 4 and middle casing 5 are respectively uncovered structure, and middle casing 5 is sleeved in shell body 4, shell
Body 4 is provided with groove upwards from opening end, carries arc-shaped surface in groove, boss is set on inner housing 4, boss top carries circular arc
Face, boss are located in the groove of shell body, two arc-shaped surface composition outlet holes 6.
Beneficial effects of the present invention are：By using the design feature of shell itself, wire hole is directly set on housing
Hole, solve the technical problem that external wire harness is fixed, while avoid and fixed in the prior art by installing pressing plate additional on housing
External wire harness, the increased technical problem of electrical connector plug thickness is caused, objectively reduce the thickness of electrical connector plug.

Embodiment
Technical scheme is described in detail with reference to the accompanying drawings and examples.
A kind of electrical connector plug, it is characterized in that：Described plug includes shell body 4 and middle casing 5, the He of shell body 4
Middle casing 5 has the structure inside and outside insertion housing in corresponding position, after shell body 4 and the installation of middle casing 5 are fixed
The inside and outside outlet hole 6 of connection electrical connector plug is formed, the external cord beam of electrical connector plug is drawn by outlet hole 6
Go out.The structure inside and outside insertion housing described in the technical program includes diversified forms, can be processed respectively on two housings
The docking of through hole or two uncovered structures either other be provided with shell structure can realize that combination utilizes
The other structures of the appearance hole formed inside and outside insertion electrical connector plug.
Embodiment
As seen in figures 3-6, the electrical connector plug described in the present embodiment includes shell body 4 and middle casing 5, shell body
4 and middle casing 5 be all uncovered structure, i.e. one end open body structure, electric elements and circuit are installed in enclosure interior
Arrangement etc..Middle casing 5 is sleeved in shell body 4, i.e., two openings are relative, and shell body 4 is sleeved in middle casing 5, both
A hollow body structure is formed, electric elements, arrangement circuit etc. are installed in casing.Wherein, on shell body 4 from open-mouth to
On be provided with one end closing open at one end groove, groove insertion housing inside and outside, the blind end of groove is provided with arcwall face.
One is provided with middle casing 5 has certain thickness boss, and the side of boss and other sides of housing connect
Connect, form the enclosed construction of an open at one end, be i.e. boss belongs to a part for middle casing side, in general the thickness of boss
Degree should be more than or equal to the thickness of side.Due to being provided with arcwall face above boss, ensureing the thickness of boss also for increasing
Greatly with the contact area of external wire harness, avoid damaging external connection Shu Zaocheng.The height of the convex platform of middle casing 5 is less than shell body
The length of groove on 4, when shell body 4 and middle casing 5 are fixed by screw 7, the boss on middle casing 5 is located at shell body 4
The inside of upper groove, i.e. groove are sleeved on boss.One is formed between the boss on groove and middle casing 5 on shell body 4
The through hole penetrated inside and outside electrical connector plug, the through hole is outlet hole 6.
It is reliable fixed to ensure to do up external connection, avoid butt welding point from causing to damage.Outlet hole 6 will to external connection beam
There is certain clamping force, even outlet hole is circle, then diameter is less than external beam diameter, transversal equivalent to outlet hole
Face area is less than external wire harness cross-sectional area, if outlet hole is irregular shape, can be carried out from cross-sectional area
Limit.No matter it is defined from which angle, is provided to ensure chucking power of the outlet hole 6 to external connection beam, realizes external
The fixation of wiring beam.Meanwhile on the face that outlet hole 6 contacts with external wire harness, in the technical program i.e. on boss
In cambered surface in cambered surface and groove, annular knurl is machined with increasing friction force, realizes the reliable fixation of external wire harness.
This gives a kind of scheme for realizing electrical connector plug, and other can realize insertion housing external and internal compositionses
Technological means also have a variety of modes of texturing, be included on housing and process through hole respectively, two the overlapping of through hole realize structure
Outlet hole 6, the clamping action to external connection beam is realized by the size of through hole in adjustment housings.Or by shell body 4 with
Between housing 5 realize that counterpart is fixed, be different from the mode being socketed in embodiment, it is recessed to process arc respectively in the opening end of two housings
Face, two arc-shaped concaves form the outlet hole 6 inside and outside an insertion Electric plug with shutter, real by the size for adjusting arc-shaped concave
Reveal blessing fixation of the string holes hole 6 to external connection beam.Other deformations fall within the protection domain under this patent core concept.
