Abstract

The utility model discloses an electric connector used for connecting circuit boards. The electric connector comprises an insulating body and a plurality of conductive terminals contained in the insulating body, wherein the insulating body comprises a side wall and a butt joint slot enclosed by the side wall. Each of the conductive terminals comprises a contact part and a weld part which is connected with the contact part and extends out of the insulating body. The outer surface of the side wall is inward dented to form a groove. The contact part is fixed in the groove. In the arrangement, the utility model can efficiently prevent the contact part from outward flicking.

Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refers in particular to a kind of electric connector that is used for the connecting circuit plate.

[background technology]

Usually need to be provided with electric connector on the electronic equipment such as computer, mobile phone in order to the circuit board that connects mutual isolation, this type electric connector generally comprises and is separately positioned on two pin connector and socket connectors on the circuit board, the prior art relevant with the utility model can be referring to No. the 2004/0157478th, U.S. Patent Publication, the pin connector that this patent discloses comprises insulating body and is contained in plurality of conductive terminals in the insulating body, the weld part in order to weld mutually with circuit board that described conducting terminal is provided with contact site and links to each other with contact site.The contact site of described conducting terminal not complete stability is immobilizated on the insulating body, and moderate finite deformation can take place, and therefore, the easy outer bullet of this contact site also extends insulating body, too much departs from the outer surface of insulating body.On the one hand, the outer bullet of conducting terminal contact site makes the conducting terminal distortion of socket connector that elastic failure too much takes place easily; On the other hand, the outer bullet of contact site causes upwards skew of weld part easily, is unfavorable for the electric connector surface soldered on the related circuit plate.

[utility model content]

The purpose of this utility model is to provide a kind of electric connector reliable, easy to use that docks.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of electric connector, in order to the connecting circuit plate, comprise insulating body and some conducting terminals that is contained in the insulating body, wherein, insulating body comprises sidewall and the docking groove that is surrounded by sidewall, and conducting terminal comprises contact site and the weld part that extends insulating body that links to each other with contact site, described sidewall outer surface caves inward and is provided with groove, and contact site is immobilizated in the groove.

Compared with prior art, the contact site of the conducting terminal of the utility model electric connector is immobilizated on the groove of insulating body sidewall, conducting terminal can not depart from the outer surface of insulating body sidewall and outwards eject, thereby, during use, realize well contacting between the conducting terminal of conducting terminal and butt connector, the conducting terminal distortion of having avoided butt connector too much and elastic failure takes place; In addition, when conducting terminal welds mutually with the corresponding circuits plate, be immobilizated on the insulating body because contact site is stable, the weld part that links to each other with contact site can upwards not be offset and have good flatness, and it is convenient that welding becomes.

[embodiment]

See also Fig. 1 to shown in Figure 5, the utility model electric connector 100 is to be used for matching with butt joint electric connector 2, comprise insulating body 10, be contained in the plurality of conductive terminals 11 in the insulating body 10 and be fixed on the insulating body 10 in order to strengthen the bonding pad 12 of welding effect.Described insulating body 10 comprises sidewall 101,102,103,104 and the diapire 105 that links to each other with sidewall 101,102,103,104, surround a docking groove 106 between described sidewall 101,102,103,104 and the diapire 105, wherein, the middle part that is positioned at horizontal sidewall 101,102 is provided with the accepting groove 1011 in order to accommodate conducting terminal 11, the outer surface of sidewall 101,102 caves inward and is provided with some grooves 1012 that are positioned at accepting groove 1011 outsides, and this groove 1012 is wide at the top and narrow at the bottom; Being positioned at longitudinally, the middle part of sidewall 103,104 is respectively equipped with convenient butt joint and realizes the recess 1013 of location.The outer surface of sidewall 103,104 caves inward and is formed with the holding slot 1014 in order to fixing bonding pad 12 of several fonts.

Described conducting terminal 11 comprises contact site 111, from the stretch out weld part that forms 112 and extend the holding parts 113 that forms from contact site 111 other ends of contact site 111 1 ends.Described contact site 111 is provided with in order to strengthen the protuberance 114 of contact effect, can be provided with respectively on described contact site 111 and the holding parts 113 in order to strengthen the protruding thorn 115 of fixing effect.

See also Fig. 2 to shown in Figure 3, during assembling, the holding parts 113 of conducting terminal 11 is fastened in the accepting groove 1011 of insulating body 10, the contact site 111 of conducting terminal 11 and groove 1012 interlock and hold and be fixed in the groove 1012, the outer surface of the outer surface of contact site 111 and sidewall 101,102 roughly is positioned at same plane, weld part 112 extends the sidewall 101,102 of insulating body 10, to be welded on the circuit board (not shown).

See also shown in Figure 5, when electric connector 100 matches with butt connector 2, conducting terminal 11 contact sites 111 are realized electrically connecting with the conducting terminal 21 of butt connector 2, because contact site 111 stable being immobilizated in the groove 1012 of insulating body 10, on the one hand, outer bullet can not take place and can prevent that conducting terminal 21 distortion of butt connector 2 from elastic failure too much taking place in contact site 111, thereby has guaranteed the good electrically contact between the connector; On the other hand, weld part 112 can the maintenance level and is helped surface soldered on the corresponding circuits plate.
