Abstract
An electrical connector comprises a shielding shell body, an insulating body and conductive terminals contained in the insulating body, wherein, the shielding body comprises a first shielding shell body and a second shielding shell body. A grounding locking part and a contacting part are both integrally formed on two sides of the second shielding shell body. The locking part on the plug-in circuit board corresponds with a holding hole while the contacting part is conducted with the first shielding shell body. The insulating body comprises a containing part and a fixing part which is vertical to the containing part. The first shielding shell body covers the containing part of the insulating body while the second shielding part covers the fixing part of the insulating body. The utility model simplifies the whole structure of the electrical connector by adopting the structure and at the same time enhances the shielding effect of the electrical connector against the EMI (electromagnetic interference).
Description
[technical field]
The utility model relates to a kind of electric connector, refers in particular to a kind of high density electrical connector that is installed on the circuit board and has preferable anti-electromagnetic interference.
[background technology]
In electronics industry, circuit board and other electronic installations are often realized electrically connecting by electric connector.Electric connector then is fixed on the circuit board by both sides installing retaining component.Simultaneously, in order to shield EMI (electromagnetic interference), adopt the metal shell of ground connection to be coated on the periphery of electric connector insulation shell usually.Relevant prior art can be with reference to United States Patent (USP) the 4th, 512, and 618,4,943, No. 244 etc.See also shown in Figure 1ly, existing electric connector 12 comprises longitudinal insulating body 18, is coated on metal shielding casing 10, plurality of conductive terminals 29, catch member 14 and the retaining component 16 of insulating body 18 interfaces.Wherein, shielding casing 10 lower end edge insulating bodies 18 lower ends extend back and are provided with grounding parts 40, catch member 14 is secured to shielding casing 10 on the insulating body 18, retaining component 16 passes the through hole 42 on the grounding parts 40 of the holding hole 28 of insulating body 18 and shielding casing 10 ends successively, and be secured on the circuit board, electric connector 12 is installed with on circuit board, reaches simultaneously and cover effect.
Yet, above-mentioned electric connector realize covering the required element of effect more, install loaded down with trivial detailsly, both be unfavorable for reducing cost, be unfavorable for again enhancing productivity.And in use, 16 of its shielding casing 10 and retaining components easily produce loosening, and the function of shielding of 10 couples of EMI of shielding casing will be weakened like this.
[author content]
The purpose of this utility model is to provide a kind of defective that can overcome above-mentioned prior art and simple in structure and have an electric connector of good screening effect.
The purpose of this utility model is achieved through the following technical solutions: the utility model electric connector comprises shielding casing, insulating body and is contained in the conducting terminal of insulating body, wherein shielding casing comprises first shielding casing and second shielding casing, the second shielding casing both sides are all one-body molded latch part and contact site, wherein corresponding holding hole and ground connection on the latch part grafting circuit board, the contact site and first shielding casing connect.Insulating body comprise the resettlement section and with perpendicular Fixed Division, resettlement section, first shielding casing is coated on the insulating body resettlement section, second shielding casing is coated on the insulating body Fixed Division.
Compared to prior art, because latch part of the present utility model and shielding casing are one-body molded, both simplified the overall structure of electric connector, also improved the shield effectiveness of electric connector simultaneously to EMI.

[embodiment]
Please refer to Fig. 2 and shown in Figure 3, the utility model electric connector 1 is a kind of high density electrical connector that is installed on the circuit board (not shown), comprises shielding casing 2, insulating body 3 and plurality of conductive terminals 4.
The roughly L-shaped lengthwise body of insulating body 3, comprise resettlement section 31 and with perpendicular Fixed Division 32, resettlement section 31.Be provided with the terminal containing slot 33 that several run through resettlement section 31 and Fixed Division 32 in insulating body 3 inside.And be provided with locating convex block 34,35 and 36 corresponding to the position of fastener 21b, 21d on the shielding casing and 22d in its outside.
Please refer to shown in Figure 4ly, during assembling, earlier conducting terminal 4 is installed in the terminal containing slot 33 of insulating body 3.Then second shielding casing 22 is coated on the periphery of insulating body 1 Fixed Division 32, and the locating convex block on bending fastener 22d and the insulating body 36 fastens.Again resettlement section 31 windings of first shielding casing 21 and insulating body 3 are in the same place, fastener 21b corresponding on locating convex block 34 and first masking device 21 on the insulating body 3 is fastened, and the locating convex block 35 that bends simultaneously on fastener 21d and the insulating body fastens.At this moment, the contact site 22b of second shielding casing 22 is contained between first shielding casing 21 and the insulating body 3, and its engaging piece 22e overlaps mutually with another lengthwise side (not label) of first shielding casing 21, and second shielding casing 22 and first shielding casing 21 are electrically connected.At last latch part 22a is plugged on the circuit board corresponding holding hole, and with circuit board on the ground path conducting, thereby reach the shielding effect to EMI of shielding casing 2.
