The processing method comprises the following steps of: performing primary injection molding in a primary injection molding die to form the primary injection molding block; arranging all contact pins into contact pin holes formed on the primary injection molding block, and bending one end of each contact pin; and arranging the primary injection molding block which is filled with the contact pins and serves as a core die in a shell die to perform secondary injection molding, and forming the plastic shell which is connected with the pin base into an integral structure outside the primary injection molding block.
Description
Technical field
The present invention relates to a kind of automotive engine control modular connector assembly and processing method thereof.
Background technology
Automotive engine control modular connector assembly of the prior art generally comprises aluminum hull, plastics needle stand and contact pin, and contact pin is fixed in the pin hole that the plastics needle stand is provided with, and the plastics needle stand is fixedlyed connected with aluminum hull.The automotive engine control modular connector assembly of said structure is because aluminum hull and plastics needle stand are two kinds of materials, and the product processes more complicated causes production cost higher; In addition because the plastics needle stand volume of fixing plug pin is bigger, take place easily by contact pin the stress influence of PCB to be caused problems such as the contact pin welding ends comes off because of the plastic contraction distortion.
Summary of the invention
Technical problem to be solved by this invention provide a kind of process simple, cost low and can effectively prevent automotive engine control modular connector assembly and the processing method thereof that the contact pin welding ends comes off.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of automotive engine control modular connector assembly, comprise injection moulding piece, stay, contact pin, needle stand and plastic casing one time, contact pin is fixed in injection moulding piece, contact pin is fixed on the end in the injection moulding piece and is provided with 100～170 degree bending angles, the unsettled end of contact pin is provided with 100～170 degree bending angles, needle stand and plastic casing together injection moulding and with injection moulding piece structure that is connected as a single entity, stay is fixed on the plastic casing, and stay is provided with the pin holes that matches with contact pin.
The processing method of above-mentioned automotive engine control modular connector assembly is: at first carry out an injection moulding and form an injection moulding piece in an injection mold; Then all contact pins are installed in the pin holes that injection moulding piece is provided with, and bend at an end of contact pin; An injection moulding piece to filling contact pin again is placed on as core and carries out quadric injection mould in the outer casing mold and form injection moulding piece outside and the be connected as a single entity plastic casing of structure of needle stand.In order further to play the stress buffer effect, when carrying out quadric injection mould, the end face that contact pin does not bend in injection moulding piece is not covered by in the plastics of quadric injection mould, one time all the other each end faces of injection moulding piece all are covered by in the plastics of quadric injection mould, the contact pin that will not bend then leaves an injection moulding piece end face certain distance to carry out secondary and bends, thereby forms unsettled bending angle at the other end of contact pin.
The beneficial effect of automotive engine control modular connector assembly of the present invention is: replaced aluminum hull of the prior art by utilizing with the incorporate plastic casing of needle stand, made that product weight alleviates, product processes is oversimplified, production cost reduces; By the design of an injection moulding piece, the plastic monolith that has reduced fixing plug pin is thick, prevents the technical problem because of expecting that contact pin welding ends that former resulting plastic contraction distortion such as thick causes comes off easily; Because contact pin is provided with bending angle, two places, the bending angle of PCB end contact pin is arranged on the outside of an injection moulding piece, play the stress buffer effect, thereby reduce the distortion of plastic when being subjected to thermal shock, therefore can prevent effectively that the contact pin welding ends from coming off by the stress influence of contact pin to PCB.
The invention will be further described below in conjunction with the drawings and specific embodiments.
