In addition, original connector is realized being connected with PCB by the threading welding, and the components and parts welding on connector welding and the pcb board is that gradation realizes, the pcb board electronic devices and components that welding easily causes through multiple high temp are fragile, the difficulty that connector is reprocessed behind the scolding tin is big, the connector of original structure is prone to the sealing-off phenomenon because the elasticity pin of needle-bar constantly touches in impact endurance test shock simultaneously, simultaneously high-temperature soldering cost height.For stability and the fail safe that improves product, simplify production process, enhance productivity, need improvement badly to meet the demands.
[summary of the invention]
The purpose of this utility model is to have overcome above-mentioned defective, provide a kind of composite type and can by flexible crimping and pcb board touch mutually the double density compression connector.
The purpose of this utility model is achieved in that a kind of double density compression connector, and its improvements are: it is made up of fixed support and at least one group, every group two linkage units that are arranged side by side; Described linkage unit comprises insulator, is packaged with contact in the insulator, and it is provided with in sidewall and is used for the support bracket fastened groove of inlay card;
In the said structure, described linkage unit insulator is provided with projection and the recess that is used to fasten the location in its horizontal two side correspondence; Described groove is arranged at the insulator vertical sidewall;
In the said structure, described groove comprises two, is arranged at the vertical two side of insulator respectively;
In the said structure, described two linkage units comprise at least two contacts that are provided with at interval, and the contact two ends stretch out in described insulator two different end faces respectively and are formed with PCB terminal and needle-bar terminal, and its middle part is for being used to be electrically connected both conductors;
In the said structure, the needle-bar terminal of described two linkage unit contacts is and shifts to install;
In the said structure, the PCB terminal of described contact is provided with flexible crimping structure;
In the said structure, described fixed support becomes the U font, and the one lateral edges is provided with the breach with the insulator interference engagement;
In the said structure, described contact plastic packaging is in insulator.
Than common connector, the beneficial effects of the utility model are to have adopted the structure that is arranged side by side by many groups, every group dual link unit insulator, and thereby insulator has guaranteed confining force between the two by injection moulding encapsulation contact, effectively solve defectives such as insulator wall thickness in the original structure, easily starved, intensity be little, avoided moving back PIN, problem such as crooked simultaneously.This external contact PCB terminal place has adopted flexible crimping structure, in use can be by this connector is applied certain pressure, can finish and being electrically connected of pcb board, and saved cost greatly, improved production efficiency.

[embodiment]
Below in conjunction with accompanying drawing the utility model specific embodiment is described in detail.
As shown in Figure 1, the utility model relates to a kind of double density compression connector, and it is by fixed support 5 and group, every group of two linkage units that are arranged side by side are formed at the most.Each linkage unit includes insulator 3,4, insulator 3,4 is equipped with in the vertical direction two side and is used for the support bracket fastened groove of inlay card, in insulator 3,4, also be packaged with contact 1,2 by injection moulding, promptly guaranteed the confining force of 3,4 of contact and insulators thus, thereby prevent that effectively contact 1,2 from moving back PIN, phenomenon such as crooked in long-term the use, injection molding process can also effectively solve problems such as insulator 3,4 wall thickness, easy starved, intensity are little simultaneously.
As Fig. 2,3, two linkage units are in its insulator 3,4 horizontal two sides, promptly be provided with corresponding recess 8 and projection 9 in the side that links to each other side by side each other, thereby can use for reality by firm complete connector of formation by fixed support 5 again after 3, the 4 stack amalgamations of the insulator of two linkage units, and can adjust PIN pin number as required at any time, very convenient.
Referring to Fig. 4,5, two linkage units contact 1,2 also comprise a plurality of usually, and 1,2 of a plurality of contacts are to be provided with at interval, thereby contact 1,2 two ends stretch out in 3,4 liang of different end faces of corresponding insulator (these both ends of the surface are mutually perpendicular level and vertical plane usually) respectively are formed with PCB terminal and needle-bar terminal, and contact 1,2 middle parts are then for being used to be electrically connected both conductors.The PCB terminal of above-mentioned contact 1,2 is provided with the flexible crimping structure that is similar to the barb buckle, thereby in use can be by this connector is applied certain pressure, flexible crimping structure directly is electrically connected with the printed circuit board realization, and flexible structure can guarantee contact reliability, promptly saved cost, also improved production efficiency, and whole maintain and replace is more convenient.
If need further to improve the test density of this patent connector, can be by the wall thickness 7 of control insulator 3,4, simultaneously the needle-bar terminal of the contact 1,2 of every group of two linkage units is mutually and shifts to install, can upgrade to double density for test by the Dan Mi that is arranged side by side.
