Description

The socket electric connector

The utility model is about a kind of electric connector, is meant that especially a kind of language signal that is used for transmits, and the socket electric connector with good earth effect.

At present, electric connector is equipped with the metal shell that is used to cover, so that prevent outside electromagnetic interference, but along with dataphone develops rapidly, the electronic building brick that is disposed on the host computer is more and more little, and the transmission of telecommunication is more and more fast, and also more and more high to the quality requirement of telecommunication transmission.Thereby existing metal shell as simple coating effect is though have the protective action of covering.Most computer assembly scattered out on the motherboard electromagnetic interference is non-to be solved by outer coating by metal shell yet come from.Especially, when butt connector docks with it, how to avoid electromagnetic interference in the motherboard, to guarantee the real problem of telecommunication transmission quality for remaining to be broken through.With regard to regard to the socket electric connector, existing structure is United States Patent (USP) the 5th as shown in Figure 1,092, No. 795, Japanese Utility Model case and for example shown in Figure 2 61-74977 number etc., the metal shell of these existing socket electric connectors all is simple coatings and do not have the measure that prevents that the motherboard internal electromagnetic from disturbing, thereby, influence for the telecommunication transmission is quite big, and interference is usually arranged, and the quality that makes this type of electric connector telecommunication that is used for the transmission of speech signal transmit is very undesirable.

The purpose of this utility model is to provide a kind of jack connetor that has good screening effect, two ground connection effects are arranged.

For achieving the above object, socket electric connector of the present utility model by the following technical solutions, it mainly comprises: metal shell, insulating body, earth terminal and signal terminal, wherein metal shell is one of the forming, it is provided with upper surface, a left side, right flank and trailing flank, extend forward and interface through being bent to insulating body forms a resilient abutment face by upper surface, the spigot of the corresponding insulating body of this resilient abutment face is the arch breach, the side also is provided with shell fragment within it simultaneously, can contact with earth terminal, make metal shell to form grounded circuit by motherboard.

Relatively prior art the utlity model has two grounding functions, and its metal shell manufacturing simple, have favorable elasticity and an indeformable advantage, in addition, because this metal shell is the structure that integrated punching is shaped, not only coats and make good use of, and have good screening effect.

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

As shown in Figure 3, the utility model socket electric connector mainly comprises metal shell 1, first insulating body 2, earth terminal 3,

signal terminal

4,5,6,7 and second insulating body 8, wherein, metal shell 1 is that the integrated punching bending is shaped, it is provided with upper surface 12, a left side,

right flank

13,14, trailing flank 15 and resilient abutment face 11, wherein resilient abutment face 11 is that front-end edge by upper surface 12 extends forward and forms through bending, and the upper surface 12 that forms with metal shell 1 in two lateral incisions, one conduit 18 of next-door neighbour's first insulating body 2 upper surfaces 23 (seeing aftermentioned for details) is separated, the socket 27 (as shown in Figure 5) of these resilient abutment face 11 corresponding first insulating bodies 2 forms an arch breach, and it is a slight inclination and form the setting with pretightning force, in order to lean with the baffle plate (not shown) that this jack connetor is installed, machinery electrically connects and the formation grounded circuit to constitute, and better contact effect can be provided.In addition, in the left and

right side

13,14 and the following ora terminalis of trailing flank 15 be equipped with several trips 16, in order to first insulating body 2 on draw-in groove 202 buckle (seeing aftermentioned for details) mutually, simultaneously, medial surface at left surface 13 also is provided with shell fragment 17 (as shown in Figure 4), can contact with ground strip 3 by this shell fragment 17, make metal shell 1 can pass through motherboard (not shown) ground connection.So make metal shell 1 have the effect of two ground connection by resilient abutment face 11 and shell fragment 17.

This first insulating body 2 is to make with a kind of resin material, it is provided with interface 21, in order to connect with butt connector (not shown), be composition surface 22 (please refer to Fig. 4) and be connected with these interface 21 lower limbs, this composition surface 22 is that first insulating body 2 engages part with second insulating body 8 (seeing aftermentioned for details).In addition, being connected with interface 21 left and right sides edge is left and
