Electric connector
[technical field]
The utility model relates to a kind of electric connector.
[background technology]
In the technology relevant with the utility model, electric connector generally has the plug of pin type terminal to circuit board in order to electric connection.This electric connector comprises the insulating body that is provided with terminal containing slot and is placed in plurality of conductive terminals in the insulating body accepting groove.During use, the pin type terminal of plug is inserted in the terminal containing slot electrically contacting with conducting terminal, and conducting terminal is connected on the circuit board, thereby has realized the electric connection between plug and the circuit board.
Two shell fragment clampings of the general employing of above-mentioned electric connector pin type terminal mode and are connected, one side of a shell fragment contact pin type terminal, it is the single-point contact, yet, having under the specific environment of sharp pounding, this single-point way of contact then may cause the loose contact of electric connector and plug.
Therefore, necessary existing electric connector is improved to overcome the defective of prior art.
[utility model content]
The purpose of this utility model provides a kind of electric connector that firmly contacts with banjo.
The purpose of this utility model is achieved through the following technical solutions: a kind of electric connector, generally connect with the plug that has the pin type terminal, it comprises insulating body and is contained in the interior conducting terminal of insulating body, described conducting terminal comprises base portion, from upwardly extending shell fragment in base portion top and the weld part that extends downwards from the base portion bottom, described shell fragment bends out first contact site, and this first contact site lower end also stamps out second contact site with the first contact site homonymy.
The purpose of this utility model can also be achieved through the following technical solutions: a kind of electric connector, generally connect with the plug that has the pin type terminal, it comprises insulating body and is contained in the interior conducting terminal of insulating body, described conducting terminal comprises base portion, from the base portion top upwardly extending a pair of relative shell fragment and the weld part that extends downwards from the base portion bottom, each shell fragment is provided with first contact site and second contact site that joins continuously and protrude towards another shell fragment.
Compared to prior art, each shell fragment of the utility model conducting terminal became present front and back two point contact with the contact of corresponding pin type terminal by former single-point contact, also just improved the stability that the utility model electric connector cooperates with corresponding plug.

[embodiment]
Please join Fig. 1 to shown in Figure 5, the utility model is a kind of electric connector 100 that is welded on the circuit board (not shown), and this electric connector 100 generally connects with the plug (not shown) that has the pin type terminal.Described electric connector 100 comprises insulating body 20 and some conducting terminals 30 that is contained in the insulating body 20.
Insulating body 20 roughly is long rectangle, and it comprises main part 21 and is positioned at the projection 22 of main part 21 all sides.Be provided with two rows in the main part 21 and be the terminal containing slot 211 that array row establishes, these terminal containing slots 211 run through the end face and the bottom surface of main part 21 up and down, and the top of terminal containing slot 211 is formed with the introduction part 212 that is the inclined-plane.
Conducting terminal 30 is made by metal material, and it has a base portion 31, and this base portion 31 comprises flat part 311 and from flat part 311 both lateral sides ends outward extending extension 312 respectively, these extensions 312 are symmetrical arranged.The top of each extension 312 is extended with shell fragment 32, described shell fragment 32 also is symmetrical arranged, each shell fragment 32 is provided with first contact site 321 and second contact site 322 that joins continuously and protrude towards another shell fragment 32, described first contact site 321 is bent to form by shell fragment 32, and described second contact site 322 forms from the mode of first contact site, 321 lower ends by punching press, and second contact site 322 extends towards the base portion 31 of conducting terminal 30, and second contact site 322 is than first contact site, 321 more close another shell fragments 32 on described each shell fragment 32, in addition, described extension 312 outboard ends also are provided with the holding section 313 that roughly is wedge shape.In addition, described flat part 311 tops and bottom are outward extended with restrictions 314 and weld part 315 respectively.
During assembling, the terminal containing slot 211 of conducting terminal 30 correspondences insulating body 20 inserts from lower to upper, and conducting terminal 30 is by holding section 313 firm being contained in the terminal containing slot 211 of extension 312.
During use, the pin type terminal of banjo can elder generation contact with first contact site 321 of the shell fragment 32 of the utility model conducting terminal 30, then, described pin type terminal can continue to insert and contact with second contact site 322 of shell fragment 32, like this, each shell fragment 32 became present front and back two point contact with the contact of corresponding pin type terminal by former single-point contact, also just improved the stability that the utility model electric connector 100 cooperates with corresponding plug.
Below only be preferred embodiment of the present utility model, other any improvement conversion of being done on the present embodiment basis also should not break away from the technical solution of the utility model.
