Abstract

An electric connector for connecting electric components includes an insulating main body and electroconductive terminals. The electroconductive terminals are held in holes which are formed on the insulating main body. One end of each electroconductive terminal is provided with a fixing-supporting part and the other end is provided with a contacting part, an elastic arm is provided between the fixing-supporting part and the contacting part, and a barrier block for supporting the elastic arm is provided on one side of each hole. Thus, influence is avoided on the normal electric conduction between the electric components and the connector by the permanent deformation resulting from condensed impact force of the fixing-supporting part and the elastic arm when the electroconductive terminals are bearing pressure.

[background technology]

At present, industry is in order to connect the electric connector of electronic cards, as Figure 10, shown in 11, usually by insulating body 50, conducting terminal 60 and the shielding casing 70 that is arranged on the insulating body 50 constitute, 70 of insulating body 50 and shielding casings are provided with the receiving space 90 of accommodating electronic cards 80, on insulating body 50, also be provided with some accommodation holes 501 of accommodating conducting terminal 60, conducting terminal 60 is contained in wherein, conducting terminal 60 comprises holding parts 601 that is immobilizated in the insulating body and the elastic contact part 602 that is extended to form by holding parts 601, accommodation hole 501 1 sides are provided with the groove 502 of accommodating conducting terminal elastic contact part 602 on the insulating body, the upper surface of elastic contact part 602 outstanding grooves 502, when electronic cards 80 is inserted receiving space 90, conducting strip 801 on the electronic cards 80 and conducting terminal elastic contact part 602 connect mutually, simultaneously elastic contact part 602 is pressed onto in the groove 502, realizes electrically conducting of electronic cards 80 and conducting terminal 60.But, because when electronic cards 80 is inserted, groove 502 forms one and allows bit space, elastic contact part 602 unsettled settings, the stressed junction a that all concentrates on elastic contact part and holding parts of conducting terminal, in use electronic cards is through after repeatedly plugging, stress is concentrated more serious, conducting terminal very easily because of fatigue generation permanent deformation, no longer has elasticity, and influences normally electrically conducting of electronic cards and electric connector.

Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.

[summary of the invention]

The utility model purpose is to provide a kind of electric connector, and it can guarantee that electronic cards and electric connector excellent electrical property connect.

In order to achieve the above object, the utility model electric connector is in order to connect the butt joint electronic building brick, comprise insulating body and conducting terminal, insulating body is provided with some accommodation holes, conducting terminal is contained in wherein, and conducting terminal one end is provided with holding parts, and the other end is provided with contact site, between holding parts and contact site, be provided with elastic arm, but accommodation hole one side is provided with the stop block of support elastic arm.

Compared with prior art, the utility model electric connector is provided with the stop block that can support the conducting terminal elastic arm in accommodation hole one side of insulating body, and the holding parts that stress concentrates on conducting terminal when avoiding conducting terminal because of pressurized and the junction of elastic arm produce permanent deformation to be influenced and dock normally electrically conducting of electronic building brick and electric connector.

[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model electric connector is described further.

Please refer to Fig. 1 to shown in Figure 9, the utility model electric connector 1 is a kind of electronic card coupler, in order to connect butt joint electronic cards 3, comprise insulating body 10, lid 12 and conducting terminal 14, lid 12 is arranged on the insulating body 10 and forms a receiving space 20 of accommodating electronic cards 3 with insulating body 10.

Insulating body 10 is provided with the some accommodation holes 101 that form a line, to accommodate conducting terminal 14, accommodation hole one side is provided with curved stop block 103, this stop block 103 is provided with depression 105, because the some block points 1031 of stop block 103 formation that are arranged so that of depression 105 (only are provided with a depression in the present embodiment, so only form two block points, certainly, also can be provided with more than more than one depression to form more block point), above stop block 103, be provided with the positioning groove 107 that is connected with accommodation hole 101, be provided with slot to make way 108 to extending away from the direction of accommodation hole 101 by positioning groove 107.

Conducting terminal 14 comprises the holding parts 141 that is arranged at the one end, the other end relative with holding parts 141 is provided with contact site 142, be provided with elastic arm 143 at holding parts 141 and 142 of contact sites, be provided with weld part 144 by holding parts 141 to elastic arm 143 opposite directions extensions, weld part 144 is provided with scolder 15 (being the tin ball in the present embodiment), the width of the elastic arm 143 of conducting terminal 14 is from dwindling gradually toward contact site 142 1 ends near holding parts 141 1 ends, and this makes both had preferably by conducting terminal elasticity also has intensity preferably.

When being installed in conducting terminal 14 in the insulating body 10, the holding parts 141 of conducting terminal is contained in the accommodation hole 101 of insulating body, the elastic arm 143 of conducting terminal is contained in the positioning groove 107, the contact site 142 of conducting terminal is by extending on the slot to make way 108 upper surface of contact site 142 outstanding positioning grooves 107 on the positioning groove 107.When electronic cards 3 is inserted in the receiving space 20, the contact site 142 of electronic cards 3 compression conductive terminals 14 outstanding positioning groove 107 upper surfaces, make the conducting strip 31 on the electronic cards 3 contact with contact site 142, make to form between conducting terminal and electric connector and electrically conduct, because accommodation hole one side is provided with curved stop block 103 on insulating body, and the radian of this stop block is docked electronic cards compression back elastic arm 143 with conducting terminal radian about equally, when the electronic cards 3 of butt joint is inserted, the contact site pressurized of conducting terminal, but the elastic arm 143 of stop block 103 effective support conducting terminals, and absorption portion pressure, make the conducting terminal pressure can not concentrate entirely on the junction of the holding parts and the elastic arm of conducting terminal as existing this kind electric connector, avoid the conducting terminal stress to concentrate, produce permanent deformation and influence normally electrically conducting of butt joint electronic cards and electric connector.
