Description
Technical field:
The present invention relates to appliance field, relate in particular to the connector of car electrics and civil electric appliance, is a kind of pressure line terminal structure for electric coupler specifically.
Background technology:
The connector product that is widely used in car electrics and civil electric appliance is comprised of plastic casing, pressure line terminal and wire, at first will be in the same place by pressure line terminal and conductor compression jointing, then use injection-moulding device and injection mold that their overall package are in the same place, finish whole process of producing product, wherein the pressure line terminal material is each metalloid, finishes this product by cold punching die production.For the ease of with conductor compression jointing, the wire interconnecting piece of pressure line terminal rear end is made as the opening curved surface that cross section takes the shape of the letter U, and its front end is the tubular structure with through hole, (applying date is on June 17th, 2004 such as Chinese invention patent " splicing ear ", Granted publication CN100477403C, April 8 2009 Granted publication day) splicing ear of putting down in writing in is this structure, if can be owing to spillage causes poor electric contact during with plastic casing and terminal together injection moulding.Because the front end of existing pressure line terminal is provided with through hole, can produce spillage in the through hole during this product injection molding packaging, product can't normally be produced, cause connector contact bad, in order to remedy this defective, have to increase manufacturing procedure one, carry out manual soldering plug-hole spillage not when guaranteeing the product injection molding packaging at the through hole lower end, and then carry out the product injection molding packaging, finish process of producing product; And for guaranteeing soldering tin technique, pressure line terminal also needs to increase the electroplating surfaces with tin operation, and the increase of operation need to take a large amount of artificial and so that the raising of production cost.Connector for digital product, also there are insulating body and insulating body by being provided with terminal containing slot to cover the incompatible front end of avoiding plastic cement to flow to terminal that matches, (applying date is on April 26th, 2002 such as Chinese invention patent " improved plug connector ", May 28 2008 Granted publication day, Granted publication CN 100391056C) connector of putting down in writing in.But the most of forceful electric power connector for automobile or household electrical appliance, but do not adopt the structure of above-mentioned patent, but by mold cavity pressure line terminal is positioned, obtain the ambroin glue shell part of connector by the injection moulding one-shot forming, can save procedure of processing like this, raise the efficiency, reduce cost.And the soldering tin block of plug-hole easily comes off, and the product percent defective is high, and product quality can not be guaranteed.
Summary of the invention:
The object of the present invention is to provide a kind of pressure line terminal structure for electric coupler, described this pressure line terminal structure for electric coupler will solve the prior art pressure line terminal because its through hole meeting spillage when injection moulding, cause existing connector production operation increase, cost height, and the insecure technical problem of the quality of product.
The objective of the invention is to be achieved through the following technical solutions: consisted of by plug and conductor compression jointing end, plug portion is the sidewall sealing, has the tubular of axially extending bore, the conductor compression jointing end is the curved-surface structure that keeps partial sidewall, the cross section of this curved-surface structure takes the shape of the letter U, pressure line terminal is encapsulated by injection molding machine, wherein, be provided with lid in the plug portion lower end, the Outside Dimensions of this lid greater than the size of plug portion lower end endoporus in order to when injection moulding, this endoporus is blocked, this lid passes through Blanking Shaping, and is connected by a bit of linkage section with plug lower end sidewall.
Endoporus in the plug lower end is provided with ladder, and hole dimension is less than the Outside Dimensions of lid in this ladder minimum.
Plug portion is the cylindrical structure with through hole, and the lid of plug lower end is the plectane lid, and the diameter of this plectane lid is greater than the diameter of plug portion lower end endoporus.
It is tight fit between plectane lid and the shoulder hole.
Operation principle of the present invention is: pressure line terminal of the present invention changes former terminal through-hole structure from structure with a lid into, once produced by a secondary precise cold stamping progressive die, stamping and blanking work step place at mould, stamping-out has stayed a lid, lid is connected with terminal bodies by a bit of material, shaping step in mould (injection moulding work step) is located, this lid has just in time been blocked the through hole of product during the terminal product moulding, this lid and through hole perisporium closely cooperate, without any the gap, lid moulding place has boss it accurately to be located and prevents the injection molding packaging pressure distortion, can well guarantee during the product injection molding packaging can not produce spillage, guarantee that whole connector product normally produces.
The present invention compares with prior art, and its effect is actively with obvious.The present invention is in the pressure line terminal structure that is used for electric coupler, be provided with a lid in the lower end of plug portion through hole, this lid is blocked the through hole of plug portion during the connector injection moulding, need not manually to weld a sprue, both improved the production efficiency of connector product, reduce production cost, guaranteed again the reliability of product.If the endoporus in the plug lower end arranges a step, by this step the plectane lid is positioned and reinforces, and this step matches with the plectane lid, the easier sealing function that plays, spillage not when guaranteeing injection moulding; If take tight fit between the hole of this plectane lid and step lower end, then liquid slurry pressure closely is pressed into this stepped hole with the plectane lid when injection moulding, can spillage.

Embodiment 1:
Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, consisted of by plug 1 and conductor compression jointing end 2, plug portion 1 is the cylindric of sidewall sealing, conductor compression jointing end 2 is the curved-surface structure that keeps partial sidewall, pressure line terminal is encapsulated by injection molding machine, wherein, be provided with plectane lid 3 in the plug portion lower end, this plectane lid 3 passes through Blanking Shaping, and be connected by a bit of linkage section 4 with plug lower end sidewall, endoporus in the plug lower end is provided with ladder 5, and the minimum diameter of bore of this ladder is tight fit between plectane lid 3 and the shoulder hole less than the diameter of plectane lid.
In the reality, the tubular structure of plug portion also may be the square tube with square hole, and at this moment the lid of its lower end is a square block that is a bit larger tham this square hole inside dimension, in order to when the connector injection moulding through hole is blocked.
Certainly, the plug portion lower end also can not arrange shoulder hole, at this moment requires the diameter of this plectane lid greater than the diameter of plug portion lower end endoporus, spillage when such structure also can be avoided injection moulding.
Equally, also can not adopt tight fit between plectane lid and the shoulder hole, as long as the diameter of plectane lid just can mortar leakage prevention greater than the aperture at the minimum place of shoulder hole, the tight fit structure that just adopts embodiment 1 is the shutoff through hole more effectively, guarantees not spillage.
