Description

Electric connector

Technical field

The utility model is a kind of electric connector, the particularly a kind of stacked electric connector that can locate and protect electric connector terminal better.

Background technology

In electronics industry, electric connector usually with circuit board on the circuit electric connection.Electric connector comprises the insulating body of ccontaining terminal, and a shielding casing is used to shield the external disturbance signal, make terminal can the normal transmission electric signal and an end be fixed on plurality of terminals in the insulating body, the other end connecting circuit plate of terminal.Along with development of science and technology; electronic devices and components require more and more miniaturization; but the amount of information that each element is handled is more and more; so just the terminal density on each electric connector unit are need be strengthened; but the density that is connected to the middle extending segment on the circuit board from the terminal that electric connector is drawn is very big; if external force is arranged slightly touches; the terminal displacement; will with adjacent terminal short circuit; the number of terminals that particularly stacked a plurality of electric connectors are drawn is more, so just need a positioning protection device be set in the middle extending segment that is connected on the circuit board, terminal is isolated; in case not-go-end is bumped askew by external force or bumps disconnectedly, cause short circuit or open circuit.

Chinese patent discloses a kind of stack-type electric connector No. 00242727.3, and as shown in Figure 1, its butt joint framework 9 is integrated L shaped, has an erection part 91 and a horizontal part 92.Wherein, this erection part 91 is formed with one can organize the depressed part 93 of establishing one first connector 81, and run through in these depressed part 93 belows to this erection part 91 and between this horizontal part 92 intersections and to be formed with at least one group of containing hole 94 of establishing one second connector 82, the height of this containing hole 94 is approximately identical with the whole height of this second connector 82, or even be slightly larger than the whole height of this second connector 82, make second connector 82 can insert in the containing hole 94 easily; And, the second set terminal 821 of the set the first terminal 811 of corresponding first connector 81 and each second connector 82 connects respectively and is provided with a plurality of first location holes 921 and second location hole 922 on horizontal part 92, when each connector is set up in depressed part 93 with containing hole 94 respectively, its terminal can plug respectively in the corresponding perforation and stretch out horizontal part 92.Because the insulation framework that this butt joint framework 9 is three-dimensionals, be provided with several through holes and storage tank on it again, so the mould of making this framework is had relatively high expectations, cost is also higher relatively, and each electric connector all to be connected to one by one the insulation framework on, install comparatively cumbersome.

In addition, No. the 87202919th, Taiwan patent application, a kind of combining structure of stacked electric connector is disclosed, as shown in Figure 2, comprise several

electric connectors

71,72, a fixed component 73 and a terminal position seat 74, offer at least one electric connector storage tank 731 on this fixed component 73, with

electric connector

71,72 are fixed on the fixed component 73 after putting into storage tank 731 again, and terminal position seat 74 is fixedlyed connected with electric connector 72, and this terminal position seat 74 is provided with several location holes 741, be used for holding the extended terminal of electric connector, be fixed in the terminal that stretches out in the

electric connector

71,72 on this fixed component 73 like this and pass location hole 741 on the terminal position seat 74, thereby terminal is connected on the circuit board exactly.The positioning protection device of this structure still only is that an end of its extension links to each other with one of them electric connector because terminal position seat wherein is the three-dimensional member of a three-dimensional, and reliability is very poor.In addition, between each connector, fixed component and the terminal position seat, need the local a lot of of connection, but, owing to the quality of fit of each connector terminals and location hole is had relatively high expectations, during fabrication, the manufacturing tolerance of this insulation framework requires very high, the also corresponding rising of manufacturing cost.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, and cost of manufacture is low, and electric connector easy for installation can be with connector terminals accurately, be connected on the circuit board safely.

Principal character of the present utility model is, the terminal position protection member of one U-shaped is vertically fixed on the insulation framework of electric connector, have several terminal position holes on the diapire of this U-shaped terminal position protection member, the terminal that extends out from the insulation framework of electric connector passes these terminal position holes, is connected on the circuit board; The two side of the member of this U-shaped terminal position protection simultaneously can protect terminal can not be subjected to the collision of next door external force again, and the circuit transmission of terminal has been guaranteed in the location and the protection of having strengthened exposing the terminal outside the insulation framework.

Another being characterised in that of the present utility model, for terminal position being protected member be connected to securely on the insulation framework, consideration all is provided with tie point in the upper and lower of this member, the diapire of U-shaped member is all fixedlyed connected with the insulation framework respectively with the two side, promptly convex with at least one fixture block in the close end of insulating framework of diapire of terminal position protection member, be provided with draw-in groove with the corresponding position of this fixture block on the described insulation framework, with described fixture block secure fit; The two side of described terminal position protection member respectively is provided with at least one locating convex block near the end of insulation framework, and position corresponding with this projection on the described insulation framework is provided with location hole, is complementary with described locating convex block.Like this, can not produce displacement in the top to bottom, left and right, front and rear direction between terminal position protection member and the insulation framework, guarantee the safety of terminal more.

Can dash forward on the insulation framework of the present utility model and establish the ccontaining housing of one or more terminals; the external shielding casing that is covered with of terminal putting part; be used to shield extraneous interference signal; extended terminal all passes the location hole on the terminal position protection member from the ccontaining housing of terminal; like this, no matter to be that single electric connector or stacked connector terminals can obtain location and protection.

The utility model also comprises an earthing component, when being single electric connector, be used for baffle is connected to circuit board, when being stacked electric connector, electrically connect constituting between the shielding casing of each electric connector earlier, be connected on the circuit board, reach the effect of ground connection simultaneously, and do not need to have separately the design of ground connection.

Adopt the electric connector combination of said structure; because insulation framework and terminal position protection piece can be made respectively; simplified the mould structure of making; processing request is low, and their mounting means is also very simple and convenient, solid and reliable; stability is high; and the U-shaped structure of terminal position protection member overcome the defective that prior art exists, and the protection of terminal is more put in place, guaranteed electric connector excellent electrical property linkage function more.
