The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Show the concrete structure of the preferred embodiment of the utility model with reference to Fig. 2 and Fig. 3, described metal shell 100 is the thin sheet of metal housing of making through punching press, moulding and inclusion by by independent a slice sheet metal, and it comprises main part 10 and is arranged at the elastic cantilever 20 on the main part, a pair of preceding fixing feet 30 and a pair of back fixing feet 40.
This main part 10 forms the rectangular framework of a hollow by roof 11, left upright side walls 12, left bank sidewall 13, right upright side walls wall 14, right bank sidewall 15 and diapire 16 inclusions of disjunctor, the W of this inclusion place is positioned at diapire 16 centers, behind the inclusion, diapire 16 is a smooth slab construction.The front and back end opening of this rectangular framework forms in the framework and has the insulating base that is used for ccontaining connector and the ccontaining cavity 10a of terminal, and its front end is for ease of the standard interface 10b of counterpart to inserting of connector.Wherein, the length dimension of roof 11 fore-and-aft directions is greater than the length dimension of diapire 16 fore-and-aft directions, and the width dimensions of roof 11 left and right directions is also greater than the width dimensions of diapire 16 left and right directions, is connected by inclined wall 13,15 between diapire 16 and the sidewall 12,14.
In addition, position, the left and right sides on roof 11 and the diapire 16 is respectively arranged with perforation 10c, one is extended elastic cantilever 20 on the forward edge of this perforation 10c, this elastic cantilever 20 extends towards direction of insertion, is provided with the bending part 21 that protrudes in this ccontaining cavity 10a in the extension tail end of elastic cantilever 20.On left upright side walls 12 and right upright side walls wall 14, be respectively arranged with and aforementioned the same elastic cantilever 20 equally.These elastic cantilevers 20 are the stability of docking that is used to guarantee with the counterpart of connector.
Fixing feet 30 comprises the first basic portion 31 and the back leg 32 of disjunctor before being somebody's turn to do.Wherein, this first basic portion 31 extends by the downward one of aforementioned left and right upright side walls wall 12,14 rear positions; This back leg 32 is extended by these first basic portion, 31 downward one, and extends diapire below 16 always, and the width of back leg 32 is less than the width of the first basic portion 31 simultaneously, mat and in after leg 32 cooperate step 33 with the first basic portion 31 junctions formation first;
This back fixing feet 40 comprises second basic 41 ones and the preceding leg 42 of disjunctor, this second basic portion 41 is extended by the outside 180 degree bendings in edge place after the aforementioned first basic portion 31, and parallel being close in the first basic portion 31 after the bending, wherein, the width (with reference to size M among Fig. 3) of direction guarantees that with this second basic portion 41 has required structural strength under on the trailing edge of this first basic portion 31 needs necessarily; Should the downward one of preceding 42 extension tail ends of leg extend by the aforementioned second basic portion 41, and extend diapire below 16 always, the width of leg 42 is less than the width of the second basic portion 41 simultaneously, mat and cooperate step 43 with the junction formation second of the second basic portion 41 in preceding leg 42.
This second cooperation step 43 cooperates step 33 to be on the same horizontal plane with aforementioned first, certainly the level height of this first cooperation step 33 and the second cooperation step 43 can be for being below or above the level height of diapire 16, concrete condition is decided according to need, not to exceed.The metal shell 100 that shows present embodiment with reference to Fig. 6 is applied to the structure chart on the heightening type connector, the diapire of this connector metal shell 100 below is provided with a bed hedgehopping layer 200 as seen from the figure, this first bottom surface that cooperates step 33 and the second cooperation step 43 and this bed hedgehopping layer 200 is on approximate same elevation of water, and this forward and backward leg 42,32 stretches out under bed hedgehopping layer 200 bottom surface.
Should before leg 42 spaced apart with back leg 32 along fore-and-aft direction, this preceding leg 42 with respect to back leg 32 more be close to end before the metal shell standard docking port 10b some.
The process of fixing feet 40,30 is with reference to Fig. 4, Fig. 5 and Fig. 2 before and after concrete making of the utility model, at first in the process of making body 10, blanking molds the leg structure of deployed condition, at this moment, with reference to Fig. 4, this first basic portion 31 and the second basic portion 41 are the slab construction of disjunctor; Then carry out bending (state diagram when Fig. 5 spends for bending to 90), until (with reference to Fig. 2), second 41 parallel being close on first matrix part 31 of basic portion that this bending is gone out are spent in its bending to 180 in the relevant position at this slab construction middle part; Wherein, this second basic portion 41 need have the length of certain fore-and-aft direction, with guarantee should before leg 42 spaced apart with back leg 32 fore-and-aft directions, and preceding leg 42 more be close to end before the metal shell docking port 10b some; By this, finish the production process of whole front and back fixing feet 40,30.
Of the present utility model focusing on, should preceding fixing feet 40 be to extend by sidewall 12, the 14 trailing edge places bending of metal shell to form, comparatively speaking, because the sidewall trailing edge of metal shell is compared with its side arm leading edge, its trailing edge place have bigger on down the width dimensions M of direction and the length dimension N (with reference to Fig. 3) of leg, by this, on the one hand effectively broadening the structure width of the second basic portion 41 of preceding fixing feet 40, thereby the structural strength of fixing feet 40 before effectively strengthening, stability when guaranteeing that connector is installed on the circuit board promotes product quality; The effective length of the forward and backward fixing feet 40,30 that also can effectively extend on the other hand, and by the first cooperation step 33 and the second cooperation step 43 that elevation of water can be lower than the elevation of water of diapire 16 is set, with the structure height that realizes increasing connector, satisfy the needs of the product that structure height increases, enlarge the range of application of connector.
The above only is the preferred embodiment of the metal shell structure of a kind of HDMI connector of the utility model, is not that technical scope of the present utility model is imposed any restrictions.So every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
