Description

Connector

Technical field

The present invention relates to a kind of connector, refer to it is a kind of connector that is applicable to power-supply adapter especially.

Background technology

The electronic installation of power-supply adapter (adapter) for often using in the daily life, major function is in order to the commercial power rectification and after converting direct current to, offers power receiving equipment again, for example: mobile computer or mobile phone use.

See also Fig. 1 (a), it is the known structural representation that uses power-supply adapter as the mobile computer power supply, as shown in the figure, one end of power-supply adapter 11 is connected with cable 12 and ac plug 13, the other end then is to be connected with direct current cables (DC cable) 14 and connector 15, when mobile computer 16 is powered, need part connector 15 is inserted in the power supply receiver hole 161 of mobile computer 16, and power-supply adapter 11 can convert the alternating current via ac plug 13 inputs to direct current, and is sent to mobile computer 16 to power via direct current cables 14 and connector 15 successively.

Please consult Fig. 1 (a) again, the part that is connected between direct current cables 14 and the connector 15 is packaged by a mold 17, as for the actual ways of connecting in both inside, sees also Fig. 1 (b), and it is about connector shown in Fig. 1 (a) and the connection diagram between cable.As shown in the figure, direct current cables 14 comprises positive wire 141 and cathode conductor 142, connector 15 then has negative pole connecting portion 151 and anodal connecting portion 152, wherein the positive wire 141 of direct current cables 14 is in corresponding position with the anodal connecting portion 152 of connector 15, therefore can be directly both be adhered together, and then the anodal connecting portion 152 of the positive wire 141 that makes direct current cables 14 and connector 15 electrically connects with scolding tin 18.After needing to cross over the isolated parts 19 of positive wires 141 and connector 15 earlier as for 142 of the cathode conductors of direct current cables 14, could utilize scolding tin 18 that the cathode conductor 142 and the negative pole connecting portion 151 of connector 15 are adhered together in the mode of joint welding, to reach the effect of electrical connection.

Because general user is when plug-in connector 15; regular meeting extracts connector 15 out with double swerve or the mode of pullling in the power supply receiver hole 161 (seeing also Fig. 1 (a)) of mobile computer 16; and only connect with scolding tin 18 between the negative pole connecting portion 151 of the cathode conductor 142 of known direct current cables 14 and connector 15; the phenomenon of disengaging takes place between the cathode conductor 142 that therefore is easy to cause direct current cables 14 in double swerve or the process of pullling and the negative pole connecting portion 151 of connector 15; and make both to be electrically connected, so will make power-supply adapter 11 to power to mobile computer 16.

See also Fig. 1 (c), it shows the connection diagram between another kind of known connector and cable.Shown in Fig. 1 (c), though the conductive ring structure 153 with a hole is set between the isolated parts 19 of connector 15 and the negative pole connecting portion 151, be adhered together with conductive ring structure 153 with the cathode conductor 142 of scolding tin 18 again after making the cathode conductor 142 of direct current cables 14 pass hole 154 earlier direct current cables 14, the extension of the last conductive ring structure of again welding being finished 153 and cathode conductor 142 are toward the pressuring direction of isolated parts 19, make this extension and isolated parts 19 parallel (shown in Fig. 1 (d)), the cathode conductor 142 of direct current cables 14 is electrically connected via the negative pole connecting portion 151 of conductive ring structure 153 with connector 15.

Though, the cathode conductor 142 of direct current cables 14 is inserted the mode of welding again behind the hole 154 of conductive ring structures 153 directly that cathode conductor 142 joint welding are more firm in negative pole connecting portion 151 than shown in Fig. 1 (b) really, but because the method that the cathode conductor 142 of direct current cables 14 and conductive ring structure 153 ways of connecting still need be used welding, the cathode conductor 142 that therefore still can cause direct current cables 14 in user's double swerve or the process of pullling is from conducting electricity ring structure 153 disengagings, and can't be electrically connected, can make power-supply adapter 11 to power equally to mobile computer 16.In addition, such mode can increase the time of assembling, is unfavorable for the raising of productivity ratio.

Therefore, how developing a kind of connector that improves above-mentioned known technology defective, is the problem that presses for solution at present.
