Description

Can select the electric connector of setting height(from bottom)

The utility model relates to a kind of electric connector of electrical socket, particularly about a kind of electric connector of the setting height(from bottom) selected that is easy to assemble and has the protected type electrical socket of good earth performance.

In electronics telecommunication industry, most of system all is that the requirement according to various objectives is linked together by indivedual different units and forms, these units may be greatly to the center switch at a telecommunication networking, it also may be usefulness mouse on computers, in any case but, indivedual units are connected to each other to be needed by various types of cables, with and on plug be connected just with socket and can make the electric signal transmission.In some field, particularly in the high frequency communication, because electric signal is to circulate between different units with high frequency, therefore in the high frequency field, different electric signals often mutual to each other thousand is disturbed, and then makes the electric signal of transmission produce mistake.For avoiding this class phenomenon, in the field of electronics industry, how on individual other unit and cable connected to one another and electrical socket, plug, keep good shielding and ground connection performance just to become an important problem.In the prior art, a part of patent has disclosed relevant technology contents, and for example United States Patent (USP) the 5th, 244, and 397,5,277, No. 627 etc.But in such prior art, still have many not to the utmost satisfied problems of making us, good inadequately etc. as shielding properties, have to be solved.

In view of this, the purpose of this utility model is in order to solve the aforementioned problems in the prior, the electric connector that can select setting height(from bottom) in a kind of protected type electrical socket to be provided.

The purpose of this utility model be realize like this a kind of electric connector of selecting setting height(from bottom) promptly is provided, this electric connector has an insulating body, be provided with several in this body in order to conducting terminal to be set in passage wherein, one end of this insulating body is provided with the reference column in the precalculated position that is positioned at printed circuit board (PCB), one end of this reference column is provided with backstay, this backstay is the ladder form, and the height of its different ladders remains on the center of electric connector with chip and is a predetermined location relationship place.

The advantage of the electric connector of the utility model electrical socket is that it not only has good shield effectiveness, and it is simple in structure, and is easy to manufacture, and production cost is further reduced; It can be positioned at electrical socket on one circuit board, can be according to circuit board differing heights position and free choice device height.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Fig. 1 is a kind of three-dimensional exploded view of protected type electrical socket, and the relation of each element of electrical socket is shown;

Fig. 2 is a protected type electrical socket combination stereogram;

Fig. 3 is the cutaway view along III-III line among Fig. 2, and the shielding case of electrical socket and the syntagmatic between the body are shown;

Fig. 4 is that the protected type electrical socket is positioned at the end view on the printed circuit board (PCB);

Fig. 5 A and 5B are the embodiment end views of the utility model protected type electrical socket reference column, illustrate that it selected the state of reference column when electrical socket cooperated the circuit board of differing heights.

See also Fig. 1, it is the three-dimensional exploded view of protected type electrical socket, this electrical socket comprises an insulating body 10, have first surface 11 and opposing second surface 12 on this body 10, notch 13 is extended towards second surface 12 by aforesaid first surface 11, the bottom of this recess near but do not run through aforesaid second surface 12 form one with dock the receiving space that the plug (not shown) cooperates.An one-body molded insulating frame 14 in this notch 13, this terminal containing slot 15 is through to second surface 12 by the first surface 11 of body 10 to 15 of several terminals accepting grooves thereon, is plugged in wherein for several conducting terminals 20.In the present embodiment, several terminals accepting groove 15 only is positioned at a side of this insulating frame 14, and a side of this insulating frame 14 has several and distinguishes the guide groove 16 of looking usefulness for cooperating, and distinguishes the function of looking in order to provide when the grafting plug.

Above-mentioned body also has one the 3rd surface 18 and is connected in first surface 11 between the second surface 12, a draw-in groove 19 is positioned on the 3rd surface 18 of body 10, and the shield shell 40 of a conduction, be coated on outside the aforementioned body 10, so that function of shielding to be provided, this shield shell 40 is that a metal plate forms with punch process, and the one side has clamp 41, in the draw-in groove 19 in order to the 3rd surface 18 of inserting body 10.This shield shell 40 also has several outstanding contact chips 42, is used for doing to electrically contact with predetermined conductive path, and the periphery of conductive shield shell 40 is provided with outstanding horizontal alar part 43 and vertical alar part 44, in order to further this electrical socket 50 is positioned on the precalculated position.

This body 10 also has a pair of inserting slot 17 and pegs graft in order to accommodate a pair of fastening device 30 respectively in the both sides of its notch 13, and the hangnail 32 of its both sides of mat is fixed in wherein, this is the metal plate of a pair of punch forming to fastening device 30, its the place ahead has a snapping hole 31, in order to when the plug with butt joint cooperates, the pawl (not shown) of buckleing of power supply plug is buckled and is grabbed in wherein, is electrically connected reliably between socket 50 and plug guaranteeing.One afterbody 33 is extended back by these fastening device 30 one, and the end of this afterbody 33 has a positioning rod 34 to stretch out to the one distal process, so that protected type electrical socket 50 is positioned at (as shown in Figure 4) on the printed circuit board (PCB) 100.

The stepped form of the backstay of fastening device of the present utility model, its purpose as shown in Figure 5, when the electrical socket 50 that contains the utility model electric connector cooperates the circuit board 101 of the chip with differing heights (H1, H2) or 102 the time, can stair-stepping by this backstay 64, this electrical socket 50 is positioned on the identical height H.

At last, see also Fig. 2 and Fig. 3, as shown in Figure 2, it is each elements combination stereogram of protected type electrical socket 50, Fig. 3 is the cutaway view along III-III line among Fig. 2, the draw-in groove 19 that extends into body 10 inside on the 3rd surface 18 of its electrical socket 50 bodies 10, it is connected with aforesaid notch 13, when the clamp on this conductive shield shell 40 41 inserts this draw-in groove 19, the front end of clamp 41 may extend in the notch 13 of body 10, when cooperating with the plug (not shown) with this electrical socket 50 of box lunch, the front end of this clamp 41 can be done to electrically contact with the grounding path of plug, and makes whole connected system (electrical socket and plug) dead ground.

The electric connector of electrical socket of the present utility model can not only make electrical socket be positioned on the circuit board, more can be according to circuit board differing heights position and free choice device height.
