Description
The present invention relates to a kind of electric connector making method, relate to the manufacturing of the many and electric connector that density is high of number of terminals.
At present; along with the continuous development of communication network technique and the appearance of portable type electronic product; data transmission between the distinct electronic apparatuses is also more and more frequent; so; various electronic installations not only need to import into apace or spread out of data, and want to transmit at short notice the data of maximum, in view of this; many electronic components with data transmission function such as electric connector etc. can be provided with a large amount of conducting terminals usually.And, because of the trend of electronic device miniaturization makes electronic installation only have limited inner space, make electric connector terminal density more and more big relatively, and existing electric connector adopts the pre-mode of inserting in a row to be inserted in terminal in the insulated part, apply the power of being pressed in terminal tails again and terminal group is gone into and the method that combines with plastic parts will be difficult to accurately promptly terminal group be gone into and do not injured the insulated part of terminal or its periphery, cause the product fraction defective to improve and cause production efficiency low.Especially conducting terminal is organized simultaneously the electric connector on thin and butt joint flank that utilize for butt joint, highdensity terminal is difficult to that effective group is gone into and the structure of not destroying this butt joint flank.In addition; when being pressed into terminal and making it organize insulated part into electric connector; the welding afterbody regular meeting of terminal is improper stressed and cause its same flatness to be affected; and then the electrical difficult quality guarantee of joint of formation electric connector; this is pressed into power also may destroy the insulated part that makes the wall attenuation because of density is too high, causes many defective productss.
The object of the present invention is to provide the mode of a kind of borrow time ejection formation to make the progressively moulding of insulated part of connector terminals and its periphery, and can in manufacture process, adjust the electric connector making method of terminal direction at any time.
For achieving the above object, the present invention is by the following technical solutions: the technology that this connector terminals utilization directly is inserted in ejection formation in the mould behind twice ejection formation with the insulated part fluid-tight engagement of electric connector, the semi-finished product of wherein finishing an ejection formation have the structure that suitable runner and terminal groove etc. help twice ejaculating forming, and the semi-finished product of an ejection formation can be directly with terminal position on the tram, and carried out twice ejaculating forming again to after still the terminal of no-fix readjusts, can obtain finished product after utilizing retaining piece assembling upper shell at last.
The invention has the advantages that: this electric connector manufacturing process is simple and easy rapidly, can save numerous and diverse processing and combination step, and reduce unnecessary mould, the tool manufacturing cost, and finished product reliability and yield height after the processing, connector terminals is organized easily in suitable location to be difficult for deviating from, and the thin typeization part that electric connector is accommodated terminal is not subject to improper outside destroy, and then the stability that improves global reliability and electrically transmit, also can further simplify the checking procedure of finished product, and, utilize this mode can improve terminal flatness behind the ejection formation, reliability and stability when helping terminal butt joint and welding, and the moulding qualification rate that can improve insulated part to be improving prouctiveness, and is beneficial to the raising of working (machining) efficiency.
The invention will be further described below in conjunction with accompanying drawing and preferred embodiment.
