Description

Electric connector and shell thereof

The present invention relates to electric connector, relate in particular to the electric connector of the contact that is used for big electric current more than two and the shell of use thereof.

Electric power is widely used for the power circuit of electric or e-machine such as washing machine, refrigerator, high-frequency electronic food heater and air conditioner with electric connector.If electric connector is used for these electric or e-machines, then owing to can assemble some parts singly, be assembled into finished product at last, therefore have the making that can simplify these machines significantly and the advantage of maintenance operation.

The contact (terminal) that electric power normally will have a high current capacity more than about 1A (ampere) with (power supply) connector is housed in the good shell of dielectric voltage withstand performance between the contact and uses, and this is a kind of electric connector of special-purpose.This electric power is generally used for connecting the power line and the ground wire of electric and e-machine etc. with connector, but also is widely used for various power driving circuits such as automobile.

Typical electric connector has adopted inserted sheet contact (male type) and the receptacle contacts of being made by thicker copper or copper alloy (gynetype).187 series, 250 series and 312 serial terminals that the example of this receptacle contacts has U.S. AMP Inc. to sell.In addition, this receptacle contacts is published in No. the 3rd, 976,348, special public clear 55-11269 number of U.S. AMP Inc., 5 5-42467 number and 64-5756 number, special fair 2-43314 number, real fair 6-7580 communique and United States Patent (USP) and the 4th, in 679, No. 887 communiques etc.

Illustrated among Fig. 5 one adopt flag-shaped power contact head 10 electric connector arranged earlier.Fig. 5 (A) is the oblique view of receptacle contacts, and Fig. 5 (B) is the oblique view of all shells 20 of this connector.

Flag-shaped receptacle contacts 10 has: two

sidewalls

12,13; The lateral bending song roughly is the jack portion 11 of C font inwards; And the Elastic Contact spring 14 of the single armed beam type that base plate 16 is processed to form through otch.The free end of this contact spring 14 has block 15, is used for limiting insertion (or chimeric) degree of depth with the chimeric inserted sheet contact (not shown) of this receptacle contacts 10.The other end in receptacle contacts 10 is formed with wire socket 18 and insulator sleeve 17, is connected on electric wire (not shown among Fig. 5) and the exterior insulation foreskin with the crimp technology that has earlier.Therefore, the contact 10 that is crimped on the electric wire looks like flag, therefore is called the flag-shaped contact.

Flag-shaped receptacle contacts 10 shown in Fig. 5 (A) is housed in and is in shown in Fig. 5 (B) in the shell 20 under lid 21 closed conditions.This shell 20 is made of with the cover plate part that is connected with main part shell 23 by hinge portion 22 (also abbreviating lid as) 21 10 main part shells 23 that can insert of the contact that constitutes the electric wire terminal.Also be formed with a plurality of not shown pins that bump on 21 at lid, also form the pin that bumps that matches at the correspondence position of main body cover 23, after lid 21 was closed, two bump pin worked in coordination, and will cover 21 and remain on blocking.The inserted sheet contact (not shown) of pairing is mutually inserted from the opening 24 on the shell 20, be electric contact state with receptacle contacts 10.

In many application, particularly be used under the situation of power supply, need plural contact, these contacts are used for outlet and the loop or the ground connection of positive and negative polarities or a plurality of power supplys.When using several connectors that have only a contact, not only be difficult for installing, and will prevent connection error, so very inconvenient in the operation.

On the other hand, can design the single connector of a plurality of contacts, if but only that a plurality of connectors are integrated, be invalid, perhaps not talkative very effective.

Therefore, the purpose of this invention is to provide a kind of like this electric connector, this electric connector is effectively with a plurality of outer shell integrated, and improved mechanical strength, makes and operates all being easy to simultaneously, and include a plurality of contacts.

Another object of the present invention provides a kind of improved connector housing that can accommodate a plurality of contacts.

In order to achieve the above object, electric connector of the present invention is characterised in that, by form groove between adjacent side wall of outer shell a plurality of shells is linked up side by side, thereby obtains integrated housing.Shared lid is combined in an end of these integrated housing with hinge.On the outer wall of the both sides of this shell He in the groove, form mating component, simultaneously also form mating component, thereby shell is locked into blocking in the lump and contact is pressed into and remains on assigned position in the corresponding position of lid.In other words, the feature of electric connector of the present invention is that by the formation groove is and fixing side by side with several shells between adjacent sidewall, the interval that keeps regulation between said groove and each contact is simultaneously also as the blocking mechanism that covers.

Several flag-shaped contacts are inserted in the cavity of each shell and live common cover by locking and keep in the enclosure.When common cover is positioned at locking (latch) position, match, thereby increased the mechanical strength of electric connector with integrated housing.
