Embodiment
In order to further illustrate principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is elaborated.
Refer to Fig. 1 to Fig. 5, Fig. 1 is the perspective view of a preferred implementation of a kind of VGA interface of the utility model, Fig. 2 is the front view of the VGA interface shown in Fig. 1, Fig. 3 is the upward view of the VGA interface shown in Fig. 1, Fig. 4 is the cross-sectional view of Fig. 2 along the A-A line, and Fig. 5 is the blast structural representation of the novel VGA interface shown in Fig. 1.
VGA interface of the present utility model fills in 9 after comprising a protecting sheathing 2, plastic cement main body 3, a plurality of terminal and one.Should by the plurality of terminal and this plastic cement main body 3, fix by rear plug 9.This protecting sheathing 2 half covers on plastic cement main body 3.
Each terminal comprises a socket and a pin section.This socket is U-shaped, and this pin position is L shaped.This pin section comprises orthogonal first side and Second Edge.This first side connects this socket and this Second Edge, and the bottom of this socket is connected with this first side.
Should rear plug 9 be writing board shape, be disposed with a plurality of positioning jacks on it.The quantity of the plurality of positioning jack is 15, and accordingly, the quantity of the plurality of terminal is also 15.The plurality of positioning jack spread configuration, every row amount is 5, every registration jack is parallel, is respectively first row pin 6, second row pin 7 and the 3rd row's pin 8.Insert in a positioning jack for second time of each terminal.This positioning jack is funnel shaped, has the insertion opening of a taper and the pin fixed part of a bar shaped.This insertion opening is positioned at a surface of this rear plug 9, and the pin fixed part of this bar shaped extends to the another one surface of this rear plug 9.When this VGA interface is installed, this Second Edge inserts in the insertion opening of this taper, is inserted into this pin fixed part, and protrudes on another surface through fill in 9 after this pin fixed part from this.The end points of the plurality of pin section is in the same plane, that is, the end points of each pin section is identical to the distance on the surface of plug 9 after this.
This plastic cement main body 3 comprises that one is refuted the section of connecing, one and slot fixed part and a plurality of jointing holes of refuting of refuting the section of connecing and being connected.The plurality of quantity of refuting jointing holes is 15, and each is refuted, and jointing holes runs through this slot fixed part and this refutes the section of connecing.Each slot is contained in one and refutes among jointing holes.
This refutes the jointing holes spread configuration, is divided into 3 rows, and every row amount is 5.Any two rows refute jointing holes and all be arranged in parallel.Refute jointing holes and also be parallel to each other for any two.This 3 row refutes jointing holes and is respectively that first row is refuted jointing holes, second row refutes jointing holes and the 3rd row refutes jointing holes.This second row is refuted jointing holes and is refuted jointing holes and the 3rd row refutes between jointing holes at this first row.
This protecting sheathing covers this and refutes around the section of connecing, and has an opening, and this exterior contour and this open interior profile of refuting the section of connecing is complementary, and makes this refute refuting jointing holes and can expose in the section of connecing.
This slot fixed part has three steps, is respectively first step, second step and the 3rd step.These three steps sequentially arrange, and this distance of refuting the section of connecing of these three step distance is all not identical.It is nearest that this first step refutes apart from this section of connecing, and this refutes the section of connecing farthest the 3rd step distance.This first row is refuted jointing holes and is arranged on this first step, runs through this first step and refutes through this section of connecing.This second row is refuted jointing holes and is arranged on this second step, runs through this second step and refutes through this section of connecing.The 3rd row refutes jointing holes and is arranged on the 3rd step, runs through the 3rd step and refutes through this section of connecing.Insert this slot of refuting jointing holes through corresponding step, and extend to this and refute in the section of connecing.
The both sides of this slot fixed part respectively are provided with a screw through-hole, and the axis of this screw through-hole is parallel with this axis of refuting jointing holes.This VGA interface also comprises two screws and two nuts, and each screw inserts among a nut by a screw through-hole.
The both sides of slot fixed part also respectively are provided with a location notch.Also be provided with a locator protrusions on this nut.This locator protrusions is arranged in this location notch.By coordinating of location notch and this locator protrusions, make this nut rotate by this screw, being screwed into Shi Buhui.
With respect to prior art, because the terminal of novel VGA of the present utility model has a L shaped pin section, one side of this pin section is for being welded and fixed with socket, another side is for being fixed on this bonnet, article two, limit is mutually vertical, therefore make the utility model only need to lean on plastic cement main body and terminal close-fitting when assembling, rear plug is the structure of pin fixedly, this VGA interface just forms an open structure like this, be convenient to the circulation of hot gas, make this terminal in welding, be not easy to form cold welding, be not easy to cause the failure welding situation generations such as rosin joint, thereby make relative productivity reduce.
Further, with respect to prior art, three rows of VGA interface of the present utility model refute jointing holes and lay respectively on three steps, make hot gas more easily circulate, and more are not easy to produce the bad problems such as cold welding rosin joint, make production efficiency relatively better.
Simultaneously, further, with respect to prior art, due to the terminal shape of VGA interface of the present utility model is special and can with rear jam-pack close fit, therefore make this VGA interface to connect technique by Through-hole reflow and welded, can adopt the carrier band packing, thereby can realize machine absorption plug-in unit, reduce so artificial degree of participation, strengthen the automatic and mechanical degree, thereby further raise the efficiency.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is limited by claims and equivalency range thereof.
