Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector with flexible terminal.

[background technology]

The electric connector that a kind of known being used for connects electroacoustic component and circuit board comprises insulating body and a pair of elastic conduction terminal that is fixed in the insulating body.Insulating body is provided with a rectangular aperture at middle position, and this opening forms the electroacoustic component that a receiving space is used for accommodating butt joint.This parameatal insulating body is provided with the terminal conduit that is open upwards of a pair of symmetry, and conducting terminal is housed in this terminal conduit.Conducting terminal comprises the elasticity docking arm that is housed in the main part in the terminal conduit and extends the terminal conduit.When electric connector was installed on circuit board, the elasticity docking arm that circuit board can be oppressed terminal moved in conduit, in it is housed in the terminal conduit fully.Because the elasticity docking arm length of terminal is longer, in the process of pressing down, the position, intermediate portion is upwards heaved easily and is arrived to circuit board, makes that corresponding conducting strip well contacts on contact point and the circuit board of docking arm front end.Thereby be necessary to provide a kind of electric connector to address the above problem.

[utility model content]

Main purpose of the present utility model is to provide a kind of electric connector, and it can guarantee that corresponding conducting strip well contacts on contact site and the circuit board on the terminal elastic arm.

To achieve these goals, the utility model is by the following technical solutions: a kind of electric connector, it comprises insulating body and conducting terminal, the terminal conduit that this insulating body is provided with an outer surface and runs through this outer surface to be accommodating aforementioned conducting terminal, and conducting terminal comprises the elastic arm that the main part that is fixed in the terminal conduit and diagonally extending go out described outer surface.Described elastic arm end is provided with contact site, the part of closing on contact site of elastic arm and elastic arm away from forming a kink between the part of contact site, this kink deviates from the outer surface of described insulating body.

Compared with prior art, the utility model electric connector has following beneficial effect: its elastic arm of terminal is provided with kink, in the time of in elastic arm is housed in the terminal conduit fully, this kink can not protrude out described outer surface, thereby can guarantee that the contact site on the terminal elastic arm contacts with the good of circuit board.

Fig. 4 is that the flexible terminal of electric connector shown in Figure 1 is housed in the lateral plan in the terminal conduit fully.

[embodiment]

As depicted in figs. 1 and 2, this creation electric connector comprises insulating body 1 and a pair of elastic conduction terminal 2 that is fixed in the insulating body.Insulating body 1 is rectangle, the rectangle receiving space 12 that is used for accommodating electroacoustic component that it comprises the body 10 of a frame shape structure and is arranged on body 10 central authorities.Be provided with a pair of terminal conduit 11 that is open upwards relatively on the body 10 around the receiving space 12, this terminal conduit 11 is " n " shape, its be located at body 10 an end wall 101 and with the perpendicular two side 102 of end wall 101 on.Also be respectively equipped with the opening 111 that vertically runs through this sidewall at the two ends of sidewall 102, be provided with projection 112 in the opening 111.Body 10 also is provided with a pair of through hole 121 at the diagonal positions place of receiving space 12.

Elastic conduction terminal 2 is bent to form by a frame shape sheet metal punching press, it comprises main part 22 and the elastic arm 21 that is " n " shape, elastic arm 21 autonomous body 22 1 ends upwards bending extend and and main part 22 between be the acute angle setting, so elastic arm 21 will move to main part 22 when being subjected to the external force of effect downwards.Main part 22 is housed in the terminal conduit 11, and it comprises first, second adjutage 222,223 that is parallel to each other and the connecting portion 221 that connects first, second adjutage.Be respectively equipped with a button that extends downward vertically in first, second adjutage 222,223 outsides and hold sheet 224, button is held sheet 224 and is provided with an accepting hole 225.Button is held sheet 224 and is housed in the opening 111 on the sidewall 102, thereby its accepting hole 225 combines with projection 112 interference on the sidewall terminal 2 is fixed in the terminal conduit 11.The inboard of second adjutage 223 is bent to form a clamping part 226, and it is housed in the through hole 121 of body 10 and is used for connecting extended cable (not shown) on the electroacoustic component.

As shown in Figures 2 and 3, elastic arm 21 comprises first, second elastic arm 211,212 that is parallel to each other and the contact site 213 that connects first, second elastic arm.When electric connector was installed to circuit board, contact site 213 overlapped mutually with circuit board.First elastic arm 211 is bent to form a broken line 214 at place, contiguous centre position, and so, first elastic arm 211 is not in same plane, and it is divided into two sections 211a that are provided with in obtuse angle, 211b, and one section 211b of contiguous contact site is away from conduit end face 110.Second elastic arm 212 is provided with too.In other embodiments, these two ends are arc-shaped transition.Arc-shaped transition or broken line make to have kink between two sections of elastic arm, and this kink deviates from conduit end face 110.

Terminal 2 is housed in the terminal conduit 11, and its elastic arm 21 protrudes out the end face 110 of conduit 11.When electric connector is installed on circuit board, the contact site 213 of elastic arm 21 will be subjected to downward pressure and move to body 22, in being housed in terminal conduit 11 fully.Owing to be respectively equipped with the kink that deviates from end face 110 on first, second elastic arm 211,212, when elastic arm was depressed into horizontal level, elastic arm will be near level, the therefore phenomenon that can not occur raising up, as shown in Figure 4.That is to say that because the existence of this kink 214, the terminal elastic arm can be housed in the end face 110 times of conduit 11 fully, thereby corresponding conducting strip contacts well on the contact site that can guarantee the elastic conduction terminal and the circuit board.
