Description

Electric connector making method and products thereof

[technical field]

The invention relates to a kind of electric connector making method and products thereof.

[background technology]

LGA electric connector one big advantage is it and docks electronic component when butt joint, only need to adopt crimping apparatus with its with dock electronic component and carry out crimping and can realize the electric connection of the two, and do not need any welding operation.Relevant present technology can be with reference to United States Patent (USP) the 5th, 820, and 389,5,395,252,5,380, No. 210 cases.In these prior aries, make the LGA electric connector and make an insulating body and several conducting terminals usually at first respectively, then the conducting terminal group is fixed in the corresponding hole of insulating body.But this manufacture method is too loaded down with trivial details and be unfavorable for the enforcement of automation mode, has therefore increased the manufacturing cost of electric connector.In addition, because insulating body is that rigid plastic material is made, it is flexible very little, so the flatness on electric connector insulating body composition surface plays crucial effects for connector with the quality that is connected of docking between the electronic component.

Therefore, be necessary to invent a kind of electric connector making method and products thereof, to overcome above-mentioned defective.

[summary of the invention]

The object of the present invention is to provide a kind of electric connector making method and products thereof, reduce production costs thereby this electric connector can adopt the automation mode to make.

For achieving the above object, making method for electric connector of the present invention, may further comprise the steps: 1. become several and metal material belt to small part to be positioned at same plane and terminal blank connected to one another and connecting portion by the punching out of metal material belt one, and the blank mechanical type is electrical connected together by connecting portion, the terminal of making comprises base portion and go out first contact arm by base portion one end diagonally extending, and from free end diagonally extending second contact arm of first contact arm; 2. the base portion with described terminal blank is bonded to insulator with integrated mode, and insulator is provided with several through holes that holds terminal two contact arms; 3. by mould adjacent all around terminal bond sites is cut off; 4. two contact arms are protruded in the surface of insulator both sides respectively towards two lateral bucklings.

Electric connector of the present invention, it comprises insulator and is located in terminal in the insulator, and this insulator adopts integrated mode that insulator is coated on the terminal, and this terminal comprises base portion and two contact arms, and described base portion is embedded in the insulator.

Compared with prior art, advantage of the present invention is: insulator of the present invention adopts integrated mode that insulator is coated on the terminal, and it is made easy and be beneficial to and reduces production costs; Moreover insulator of the present invention is that elastomeric material is made, so it can guarantee conducting terminal and firm connection of docking between the electronic component.

[embodiment]

Below in conjunction with the drawings and specific embodiments the present invention is further elaborated.

See also Fig. 1 to shown in Figure 5, the method of making electric connector of the present invention is as follows: may further comprise the steps: 1. become several and metal material belt to small part to be positioned at same plane and terminal blank 1 connected to one another and connecting portion 2 by the punching out of metal material belt one, and blank 1 mechanical type is electrical connected together by connecting portion 2, described terminal blank 1 is arranged, which is provided with at least one be used for the visual discrimination position lack block 13, this lacks block 13 has some terminals to lack for a block is arranged, be used for the visual discrimination position, has foolproof function, the situation that setup error can not occur, described terminal comprises base portion 10 and two contact arms 11,11 ', before not cutting off, one contact arm 11 of a described terminal 14 is linked to the base portion 10 of another terminal 15, base portion 10 ' with the 3rd terminal 16 before the base portion 10 of described another terminal 15 does not cut off links, and the position that described terminal links is provided with the groove 12 of prejudging when punching press; 2. the integrated mode of base portion 10 usefulness with described terminal 1 is bonded to insulator 3, and insulator 3 is provided with several and holds terminal two contact arms 11,11 ' through hole 30; 3. inciting somebody to action all around by mould (not shown), the groove 12 of adjacent terminal 1 bond sites cuts off; With at least one contact arm towards a lateral buckling above insulator 3 surface, described in the present embodiment first surface of contact arm 11, second contact arm 11 ' another surface towards the opposite side bending above insulator towards a lateral buckling above insulator.Like this, described electric connector this completed.
