Abstract

The utility model relates to a plug connector, particularly a plug connector and a shell structure thereof, which is used for preventing misplug failure of butt-joint electronic elements. The plug connector is mainly provided with a shell and a plurality of conductive terminals penetrating through the shell, wherein, a specific side surface of the shell is provided with a limiting part, so that the butt-joint electronic element can be successfully plugged in only by butt-joint along the correct direction, to realize the death preventing goal for preventing misplug. The original complicated death preventing structure of the shell is simplified, to provide convenience for processing.

Description

Pin connector

The utility model is about a kind of pin connector, is meant especially to prevent to dock the improvement with shell structure of pin connector that electronic component misplugs and fool proof thereof.

At present, the existing design that is relevant to this case please refer to United States Patent (USP) the 5th, 342,221,5,131, No. 867 and Deutsche Bundespatent DE4025571A1 number and Taiwan patent the 80208826th, 82200584,83105748, cases such as 83301429 and No. 83110257, be these existing pin connectors 3 as shown in Figure 1, this pin connector 3 is provided with the housing 30 that is the square frame shape, in housing 30, be equipped with the terminal accommodation holes 31 that connects shape before and after being, and the position corresponding to terminal accommodation holes 31 convexes with several butt joint posts 32 respectively on the butt joint side of pin connector 3, insert in the butt joint electronic component so that difference is corresponding, the terminal accommodation holes 31 of pin connector 3 is further to docking the direction extension and running through butt joint post 32, so that the conducting terminal (not shown) of being accommodated in it conducting terminal interior with docking electronic component constitutes electric connection simultaneously.In addition; the butt joint post 32 of pin connector 3 is for realizing preventing to dock the anti-inserted or wrong plug of electronic component, to avoid causing the fool proof purpose of short circuit phenomenon; usually can be made as the form that differs from one another, to dock post with corner cut hexagon cylindricality be to be special being staggered to square column type butt joint post as shown in the figure.Yet though the design of these fool proofs can realize preventing the purpose that misplugs, still the profile interval variation of docking post can cause the Mold Making difficulty.

Main purpose of the present utility model is to provide a kind of corresponding fool proof mechanism that is provided with on housing, can make simplifies the structure is easy to mold design and reduces the pin connector of manufacturing cost.

The purpose of this utility model so realizes: convex with several identical square column type butt joint posts on the housing of pin connector, run through housing and the butt joint post is provided with terminal accommodation holes again and accommodates conducting terminal with correspondence, conducting terminal one end stretch into wherein with dock electronic component and electrically conduct, its other end then is exposed to pin connector and sentences with circuit board and electrically lead to, being provided with restriction two electric connectors again in the appropriate location of specific butt joint post side only can be according to the restrictions of formulating the direction winding, if and only if restrictions just can realize dock with another electronic component butt joint when aligning the relative structure of butt joint electronic component, realization prevents the fool proof purpose that oppositely misplugs whereby.

The utlity model has following advantage: it can reach and prevent to misplug, and has the effect of fool proof, and shell structure is oversimplified and the reduction manufacturing cost, is beneficial to Mould Machining, group mould and ejection formation and processes finishing rapidly of every operation, to promote production efficiency.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the schematic perspective view of existing pin connector.

Fig. 2 is the schematic perspective view of the utility model pin connector first embodiment.

Fig. 3 is the schematic perspective view of the utility model pin connector first embodiment when docking with butt connector.

Fig. 4 is the schematic perspective view of the utility model pin connector second embodiment.

Office's cutaway view that Fig. 5 is the utility model pin connector second embodiment when docking the electronic component winding.

See also shown in Figure 2, this pin connector 1 bottom has square casing 10, on the butt joint side 14 of this housing 10 corresponding to the position of terminal accommodation holes 11 respectively one convex with several butt joint posts 12, terminal accommodation holes 11 connects butt joint post 12 and housing 10, one end of conducting terminal 17 stretch in the butt joint post 12 and can with dock electronic component and electrically lead to, its other end then is exposed to outside the opposite side bottom side 15 of housing 10 with respect to butt joint side 14, to be electrically connected on the circuit board, these butt joint posts 12 and the terminal accommodation holes 11 that connects in it all are single form, be illustrated in figure 3 as square column type, and the side surface that partly docks post is provided with a restrictions at least, it is ined succession and forms in the butt joint side 14 and parallel docking post 12 definite length extended of housing 10, this restrictions is a restrictions 13 on this pin connector 1, to cooperate (being detailed later) with butt joint electronic component relative configurations, on housing 10 side wall surfaces and one extend the holding structure 16 of certain-lengths to bottom side 15, so that pin connector 1 is immobilizated on the circuit board (not shown), and conducting terminal 17 and circuit board (not shown) are electrically conducted.

See also shown in Figure 3, when this pin connector 1 when docking electronic component 5 butt joint, the restrictions 13 of pin connector 1 have only when and 50 pairs of timings of the corresponding buckle that dock electronic component 5, just can allow another dock electric component group and go into.Otherwise, the restrictions 13 of pin connector 1 will interfere with the housing wall that docks electronic component 5 and can not organize into.Like this, what this pin connector 1 can be borrowed restrictions 13 and butt joint electronic component 5 relative configurations 50 guides pin connector 1 only can be connected with group with docking electronic component 5 according to specific direction correct the cooperation, and realization prevents the fool proof purpose that misplugs whereby.Moreover, because of preventing the fool proof effect that misplugs, this can realize by restrictions, and the butt joint post that can make pin connector is single square column type, can simplify casing structure, and the every operation that makes Mould Machining, the processing of group mould and ejection formation with simplification and finish rapidly, can increase and decrease simultaneously the number of butt joint post at any time according to need, improve the shared property of mould.Shared property.

See also Fig. 4 and Fig. 5 again, the feature structure of most of member of second embodiment is identical with first embodiment, do not give unnecessary details so do not add, and difference is designed the electric connector with latching device.The housing 20 of this pin connector 2 is provided with a fixture block 28, front end has trip 29, fixture block 28 is connected in housing 20 in middle appropriate position, thereby make fixture block 28 rear and front ends have certain elasticity, when pin connector 2 when docking electronic component 4 butt joint, except that borrowing restrictions 23 prevents to misplug, the trip 29 that also can further borrow fixture block 28 with dock electronic component 4 on the fixture block 40 of establishing be interlocked and make winding firm.
