Therefore, as for the metal shell structure, the structure is simpler, the material consumption is less, the processing process is simple, the cost is reduced, the fixed feet directly and integrally extend to the lower ends of the left side wall and the right side wall, so that the fixed feet have wider base parts, further the structural strength of the fixed feet is improved, the connection of the fixed feet with a circuit board is more stable, and the length of the fixed feet also can be freely designed according to the actual needs so as to be suitable for being installed on the circuit boards with different thicknesses.
Description
Technical field
The present invention relates to the field of connectors technology, refers in particular to a kind of simple in structure, production cost is low and structural strength is high metal shell structure of electric connector.
Background technology
At present, along with the development of science and technology, various electronic products are also in develop rapidly, and be widely applied to electric connector in electronic product, and for example, HDMI (High Definition Multimedia Interface), be the HDMI connector, it has extensively become the interface standard of Digital Television and consumption electronic product; Therefore, the quality of electric connector quality can produce extremely important impact to the result of use of associated electrical product.
And the metal-back of electric connector has also played very important effect in product, for example, shielding action etc., also have, electric connector system is connected and fixed by fixing feet and the circuit board of metal-back, therefore, the structural strength of its fixing feet is also to weigh a very important factor of this metallic shell of electric connector.
Existing metallic shell of electric connector can satisfy above-mentioned needs substantially,, in actual production and use procedure, can find that also there are many weak points in the metallic shell of electric connector of prior art, for example: it is by extending also bending acquisition fixing feet in two side front end or rear end for some metallic shell of electric connector, its base portion is narrower, makes the bonding strength of fixing feet inadequate, can't satisfy the requirement of current product quality and structure; And some metallic shell of electric connector, its structural strength increases relatively,, the deficiency that also unavoidable structure was more complicated, part is more its while and bring, for example, by increasing by a crown cap in its metal-back top and extending to form the mode of fixing feet in lower end, crown cap both sides, its consumption material is more, thereby increased material cost, and its course of processing is also more complicated; And for example, by extending to form a metallic plate in metal-back diapire front-end edge and extending to form fixing feet downwards in this metallic plate both side edges, and this metallic plate is fixed on diapire by welding manner, the moulding of this kind metallic shell of electric connector is more difficult, be prone to failure welding and even scrap phenomenon in processing procedure, reduced product quality and yields etc.; So, structural strength metal-back preferably in prior art is because its higher production cost and material cost are unfavorable for market competition and popularization.
Summary of the invention
In view of this, the present invention is directed to the disappearance of prior art existence, its main purpose is to provide a kind of metal shell structure of electric connector, and it is simple in structure, be easy to processing, reduced production cost, and it has good structural strength.
For achieving the above object, the present invention adopts following technical scheme:
A kind of metal shell structure of electric connector includes integrated roof, left side wall and right side wall, and this left and right sidewall system stretches out and downward bending forms from the left and right lateral margin place of aforementioned roof one respectively; Under this left side wall and right side wall the ora terminalis place respectively one extended to form fixing feet downwards; Extend respectively at the ora terminalis place of this left side wall and right side wall and inverse bending is formed with the first wall extension and the second wall extension, and this first wall extension and the second wall extension to lay respectively at aforementioned left and right sidewall inboard; This first wall extension be connected wall extension and be interlocked to connect and enclose with aforementioned roof and form an accommodating cavity that is used for taking in insulating base, the front end of this accommodating cavity is interface.
As a kind of preferred version, described the first wall extension includes the first connecting plate and the first base plate, and described the second wall extension includes the second connecting plate and the second base plate; Wherein, this first connecting plate and the second connecting plate system respectively from aforementioned left and right sidewall front-end edge place one extend forward and backward bending form, and this first connecting plate and the second connecting plate to lay respectively at aforementioned left and right sidewall inboard; And, this first base plate and the second base plate system respectively from the lower ora terminalis place of this first connecting plate and the second connecting plate one to downward-extension and inwardly bending form, and this first base plate be connected the base plate connection that is interlocked.
As a kind of preferred version, be provided with the first stopper slot and the first stopper protrusion on described the first base plate, correspondingly, aforementioned the second base plate is provided with the second stopper slot and the second stopper protrusion, this second stopper protrusion is embedded in the first stopper slot, and this first stopper protrusion is embedded in the second stopper slot.
As a kind of preferred version, described the first base plate is respectively arranged with the connection shell fragment with being connected on base plate.
As a kind of preferred version, described left and right sidewall all in ora terminalis thereafter place one extend back and inwardly bending be formed with holding parts.
As a kind of preferred version, described roof front-end edge place one is extended forward and bending up is formed with a fixed head, and offers a fixing hole on this fixed head.
As a kind of preferred version, be provided with the connection shell fragment on described roof.
After the present invention adopted technique scheme, its beneficial effect was:
Main system goes out roof and left and right sidewall by one-body molded, and be formed with first and second wall extension in ora terminalis place's extension and the inside inverse bending of left and right sidewall, first and second wall extension being interlocked connects and encloses with roof the accommodating cavity that is formed for device insulating base and terminal again, fixing feet directly one extend under left and right sidewall and hold; Compare conventional art:
On the one hand, this fixing feet has wider base portion, thereby, improved the structural strength of this fixing feet, being conducive to this metallic shell of electric connector is connected with the firm of circuit board, simultaneously, the length of this fixing feet can freely be designed to different length according to actual needs, thereby can be fit to be installed on the electric connector that reaches differing heights on thicker circuit board;
On the other hand, structure is more simple, consumptive material is less, and its course of processing is also very simple, only needs by punching press, bending and fasten to get final product, and has saved the operations such as welding, buckle in conventional art, so, has reduced to a great extent material cost and processing cost;
And, the metallic shell of electric connector of this kind structure, it is except fastening the position, and all the other positions are all one-body molded, its bonding strength is good, avoided in the conventional art because of the loosening phenomenon of even unclamping of weld or button buckle place, and the present invention's fastenings position is the bottom position that is positioned at metal-back, during use, can put to strengthen by the pressure of insulating base the stable connection of this buckling parts, so, be difficult to occur the phenomenon that this buckling parts unclamps.
