Abstract

The utility model discloses an electric connector, comprising an isolation body and a plurality of conductive terminals. The conductive terminals are arranged inside the isolation body, comprising a connection part, a holding part and a contact part. The holding part and the contact part are matched with the isolation body. The contact part of the conductive terminal forms a plurality of contact points by a plurality of times of bending. With the arrangement, the contact area and confining force of the conductive terminal and the abutting-terminals of an abutting connector are increased, so as to improve the electric contact performance and contact dependability of the conductive terminal and the abutting-terminals of the abutting connector.

Description

Electric connector

[Ji Intraoperative field]

The utility model refers in particular to the connector terminals structure about a kind of electric connector.

[Bei Jing Ji Intraoperative]

The Xian You Ji Intraoperative relevant with the utility model can consult shown in Figure 1, Figure 1 shows that a kind of supply socket, this supply socket 1 comprises insulating body 11, first conducting terminal 12 and second conducting terminal 13, wherein first conducting terminal 11 is the projection shape and is arranged in the cavity 110 at insulating body 11 middle parts, and second conducting terminal 13 is provided with a contact site 130 that extends to described cavity 110, and described contact site 130 middle parts are protruded and formed and attaching plug (not shown) contacted one prominent point 131.Because having only one prominent 131, second conducting terminal, 13 contact sites 130 contact with attaching plug, for guaranteeing that having preferable confining force therebetween makes therebetween reliably contact, the rigidity of second terminal 13 is stronger, but this can cause at second terminal when attaching plug repeatedly inserts permanent deformation taking place and can't restore to the original state and can't contact with attaching plug, and this kind situation is as can more being prone in vibration environment.Moreover because of only adopting some contact, contact area is little, and therefore the contact resistance between second conducting terminal 13 and the attaching plug is bigger, therefore can cause defectives such as distorted signals.

[summary of the invention]

Main purpose of the present utility model provides a kind of electric connector, and this electric connector can reliably contact and have preferable electric connection effect with butt connector.

For achieving the above object, the utility model adopts following Ji Intraoperative scheme: this electric connector comprises insulating body and several conducting terminals, wherein the conducting terminal group is located in the insulating body, comprise connecting portion, the holding parts that cooperates with insulating body and contact site, wherein the contact site of conducting terminal is through repeatedly being bent to form a plurality of contact points.

Compare Yu Xian You Ji Intraoperative, the utility model is by increasing the contact site of conducting terminal this conducting terminal and dock contact area between the terminal with butt connector through repeatedly being bent to form a plurality of contact points, thereby reduce contact resistance therebetween, described conducting terminal can adopt the preferable made of elasticity simultaneously, can avoid it to produce permanent deformation thus on the one hand, and can guarantee that on the other hand conducting terminal also can guarantee reliably to contact with butt connector under vibration environment.

[embodiment]

Below with this utility model of supply socket explanation De Ji Intraoperative scheme, see also shown in Figure 2, this supply socket 1 comprises an insulating body 11, first conducting terminal 12 and second conducting terminal 13, wherein insulating body 11 inside form host cavities 110, and first conducting terminal 12 is a positive terminal in the present embodiment, comprise the docking section 120 that is the projection shape and extends to host cavity 110 middle parts, cooperate with the holding parts 121 of locating first conducting terminal 12 with insulating body 11 and stretch out the outer weld part 122 of insulating body 11 to electrically connect with circuit board (not icon), and second conducting terminal 13 comprises a tabular location division 130, with the 130 perpendicular settings of tabular location division and protrude the connecting portion 131 of insulating body 11 and from tabular location division 130 1 end reflexeds and be arranged on the contact site 132 of host cavity 110, and contact site 132 is through repeatedly being bent to form a plurality of contact points 133, then be provided with two contact points 133 in the present embodiment, cause contact site 132 to be " M " shape.

As shown in Figure 3, when butt connector (in the present embodiment for attaching plug) 2 and supply socket 1 connect, attaching plug 2 directly is inserted in the host cavity 110 of supply socket 1, wherein first conducting terminal 12 electrically contacts with the positive pole butt joint terminal 21 of being located at attaching plug 2 inwalls, and second conducting terminal 13 electrically contacts with the negative pole butt joint terminal 22 of being located at attaching plug 2 outer walls, because second conducting terminal, 13 contact sites 132 are provided with two contact points 133, therefore can make between attaching plug 2 and the supply socket 1 and have bigger contact area, can reduce contact resistance therebetween thus, when being applied in the vibration environment as this supply socket 1 simultaneously, contact site 132 can be subjected to the active force of attaching plug 2, but owing to two contact points, 133 stressed differences produce different deflections, therefore can guarantee to have at least a contact point to contact, thereby avoid opening circuit with attaching plug 2.

Really, foregoing description is that example describes with the supply socket, but this utility model De Ji Intraoperative scheme can be applied in the electric connector of other employing face contact fully.
