Description
[technical field]
The utility model relates to a kind of electric connector, refers to a kind of power connector that is installed on mobile phone inside especially.
[background technology]
The existing power connector that is used for mobile phone inside generally comprises insulating body, is contained in center terminal and the first terminal and second terminal that insulating body both positive and negative polarity interior and banjo connects.Center terminal has cylindric contact jaw, and after plug inserted, center terminal one end and banjo connected, and its other end and second terminal connect, and this second terminal other end and circuit board connect simultaneously.The first terminal one end and banjo connect, and the other end and circuit board connect, and constitute the galvanic circle with this.
Promptly disclosed this kind electric connector No. 200320120741.0 as Chinese patent application, please in conjunction with consulting Fig. 1 and shown in Figure 2, electric connector 1 is used to be installed on circuit board (not icon), and it comprises the insulating body 10 that is provided with jack 100, is contained in the insulating body 10 and center terminal 12, the first terminal 14, second terminal 16 and the 3rd terminals 18 separated from one another.Center terminal 12 comprises cylinder arm 120 and the fixing step 122 that circumferentially protrudes out from cylinder arm 120 1 ends.Cylinder arm 120 inserts jack 100 centre positions and can connect the tail end of fixing step 122 and second terminal, 16 butts with banjo 2.The first terminal 14 comprises first contact arm 140 that can connect with banjo 2 and second contact arm 142 that connects with circuit board.Second terminal 16 comprises for the tabular fixing wall 160 of fixing step 122 butts of center terminal 12 and the 3rd contact arm 162 that connects with circuit board.The 3rd terminal 18 is included in the 4th contact arm 180 that preceding and center terminal 12 that plug 2 inserts connects and the 5th contact arm 182 that connects with circuit board, the 4th contact arm 180 is provided with collets 184, after plug 2 inserted, plug 2 promotes collets 184 made the 4th contact arm 180 separate with center terminal 12.When plug 2 inserted, the fixing step 122 of center terminal 12 was connected on the fixing wall 160 of second terminal 16, utilized this kind structure fixing center terminal 12 to be moved back by excessive insertion force top preventing.
But the center terminal 12 of this electric connector 1 and second terminal, 16 independent design, the center terminal 12 and second terminal 16 need be assembled respectively during assembling, thereby make the installation step complexity, and when terminal is electroplated, need to guarantee the good electroplating effect of contact portion of the center terminal 12 and second terminal 16, thereby increased the plating difficulty and therefore increased production cost.So it is a kind of with center terminal 12 and the 16 integrated designs of second terminal that industry occurs, and utilize and hangnail is set on the terminal of one-body molded back cooperates so that center terminal is immobilizated in the insulating body with the interior appropriate section of insulating body.
Yet along with the increase of modern electrical equipment functional module and reducing of profile, electric connector structure is increasingly sophisticated, size reduces day by day, correspondingly, the structure of the center terminal of above-mentioned electric connector also reduces day by day, for guaranteeing terminal intensity, the hangnail that is provided with on the center terminal can not be too big, the insertion force when but banjo inserts electric connector is generally bigger, this moment is if only utilize hangnail fixing center terminal, produce the phenomenon that center terminal is moved back by excessive insertion force top probably, thereby can not guarantee the electrical laser propagation effect of stablizing of electric connector.
Given this, be necessary to provide a kind of improved electric connector in fact, to overcome the defective of above-mentioned electric connector.
[utility model content]
The purpose of this utility model is to provide a kind of electric connector that can reduce production costs and can guarantee stable electrical transmission.
The purpose of this utility model is achieved through the following technical solutions: a kind of electric connector, in order to be installed on the circuit board, it comprises insulating body, is contained in the insulating body and the first terminal and second terminal separated from one another.Insulating body is provided with jack, can hold a banjo with both positive and negative polarity and insert; Behind the plug insertion jack, the first terminal and second terminal connect with the plug both positive and negative polarity respectively; The first terminal comprises first contact arm that connects with plug, second contact arm that connects with circuit board and first holding parts that is connected first and second contact arms; Second terminal comprises the 3rd contact arm that connects with plug, the 4th contact arm that connects with circuit board and second holding parts that is connected third and fourth contact arm; Extension is provided with stop block on first holding parts, is provided with the backstop groove of accommodating stop block in the insulating body, and when plug inserted, stop block cooperated with the backstop groove to prevent that the first terminal from being moved back by the top.
Compared with prior art, the first terminal of the utility model electric connector is provided with first contact arm that connects with banjo and second contact arm that connects with circuit board, thereby avoid first contact arm and second contact arm are arranged at two independently on the terminal, and then simplification number of assembling steps, reduce to electroplate difficulty, reduce production costs, and, cooperate firmly to be immobilizated in the first terminal in the insulating body by corresponding backstop groove in the stop block that is provided with on the first terminal and the insulating body, thereby avoid insertion force excessive when banjo inserts that the first terminal top is moved back, and then guarantee stable electrical laser propagation effect.
