Abstract

The utility model relates to an electric connector which comprises an insulating body, a terminal base provided with an insert and a conductive terminal, a shielding casing, etc., wherein, the terminal and the insert are integrally injected to be molded; after the molding, the terminal base is inserted into the insulating body and is fixed to the insulating body; the shielding casing covers the insulating body and the periphery of the insert. The utility model is characterized in that after properly bent, the terminal extends out of the abutting end of the insert and has definite spacing with the shielding casing covering the terminal before the terminal and the insert are integrally injected to be molded, preventing the abutting end of the terminal from being too close to the shielding casing from the extending part of the insert and ensuring the stability of telecommunication transmission.

Description

Electric connector

The relevant a kind of electric connector of the utility model refers to a kind of electric connector of being connected between circuit board and network of being used for especially.

Along with making rapid progress of science and technology, electronic equipment such as computer and many communication network products are universal day by day, and especially in telecommunication equipment today of miniaturization day by day, compact and transmission telecommunication quick and precisely becomes the target that people pursue telecommunication equipment.In the design of existing electric connector, terminal and insert are the one ejection formation, will engage again into the terminal of one and insert winding on insulating body.As shown in Figures 1 and 2, be connected lengthwise body on the connecting band 14 for several two ends before this kind connector terminals 10 and insert 12 are one-body molded, these terminals 10 fuse with it through insert 12 behind ejection formation, connecting band 14 with terminal 10 two ends excises again, the two ends that terminal extends insert 12 form abutting end 16 and butt end 18 respectively, but the abutting end 16 of terminal 10 is all bent the back and winding (Fig. 3 reference) on insulating body 34 to the lower surface 20 of insert 12 with butt end 18.Because the restriction in space, the thinner thickness of insert 12, terminal 10 extends insert 12 and to form the part of abutting end 16 also very near with the distance of the upper surface 22 of insert 12, so, when shield shell 36 cover caps thereon the time, abutting end 16 tops of terminal 10 apart from the upper surface of shield shell 36 apart from t very little (Fig. 3 with reference to), in case product size has deviation slightly, cause abutting end 16 to contact easily, and then influenced the effectiveness of terminal 10 telecommunication transmission and shield shell 36 with shield shell 36.

For guaranteeing the stability of telecommunication transmission, it is to adopt the method for extending the position stickup plastic cement insulating trip of insert 12 at terminal 10 abutting ends 16 that some designs are also arranged, contact with shield shell 36 with the abutting end 16 of avoiding terminal 10, though this kind method can prevent the abutting end 16 of terminal 10 and contact with shield shell 36, but its must increase by the plastic cement insulating trip manufacturing cost and the waste resource, the institute think prevent this kind connector terminals 10 contact with shield shell 36 should seek more effective and the saving resource method.

The purpose of this utility model is that the abutting end of connector terminals and the assembling distance of insulation shell can strengthen, and can guarantee that the terminal abutting end can not contact with the shield shell of electric connector.

For achieving the above object, the utility model adopts following technical proposals to realize, the utility model electric connector mainly comprises insulating body, be provided with the terminal base of insert and conducting terminal and be coated on the members such as shield shell of insulating body, wherein but the insert winding is on insulating body, conducting terminal and insert one ejection formation, the two ends of terminal are extended insert respectively and are formed butt end and abutting end respectively through bending, the shield shell cover cap is at insulating body and insert periphery, be primarily characterized in that: terminal with insert one ejection formation before through suitably bending, and make the distance of the distance of part that the abutting end of terminal after the electric connector winding extends insert and shield shell greater than butt end and shield shell, can avoid terminal and shield shell too near and influence telecommunication and transmits.

Compare prior art, the abutting end of the utility model terminal can not contact with the shield shell of electric connector, has the stable advantage of telecommunication transmission.

The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.
