The utility model is a kind of pin connector, relates in particular to a kind of highly different conducting terminal that has, the pin connector that mating force reduces when making it to peg graft with socket connector.
The pin connector of current popular, its conducting terminal height is all identical, and need execute bigger power when pegging graft with socket connector just can be with two complete windings of butt connector.Fig. 1 is a kind of existing pin connector schematic diagram, the plug terminal 32 of this pin connector 3 has the head 321 of taper and square main body 322, when pin connector 3 and socket connector 4 were connected with group, the maximum static friction force that the female terminal 421 of plug terminal 32 and socket connector 4 needs to overcome between the two at the beginning of pegging graft just can make plug terminal 32 enter accepting groove 42.The main part 322 of plug terminal 32 contacts with female terminal 421 after the maximum static friction force that overcomes both, only need overcome the kinetic force of friction of 421 of plug terminal 32 and female terminals this moment.And according to theory analysis, maximum static friction force is bigger than kinetic force of friction, because existing plug terminal height is all identical, so, at the beginning of plug terminal 32 and female terminal 421 are pegged graft mutually, all plug terminals 32 all need overcome and the maximum static friction force of 421 of female terminals, therefore, need apply bigger power when pegging graft can insert plug terminal 32 in the accepting groove 42 of female terminal 4, so not only mating force greatly also can cause the inhomogeneous and then injury pin connector of the application of force, thereby will reduce the useful life of pin connector, also be unfavorable for the carrying out of plug and electric connector for socket operation.
The purpose of this utility model provides a kind of pin connector, and it can utilize the difference of conducting terminal deploying height, makes plug terminal formation time when inserting the accepting groove of socket connector poor, with the strength that reduces to peg graft mutually; And make grafting convenient, prolong the connector life-span
The purpose of this utility model is achieved in that is arranged to different shapes with the terminal height of pin connector, be disposed at then in the terminal containing slot of pin connector insulation shell, as clocklike arranging or modes such as irregular arrangement are provided with, and all plug terminals all have the head of taper and square main part.And the female terminal height of the respective socket connector that plugs with this pin connector is all identical.In the grafting process, the head of long plug terminal will contact with female terminal earlier like this, and the carrying out of the process of at this moment pegging graft need overcome maximum static friction force between the two; Along with proceeding of pegging graft, the head of long plug terminal has slipped in the accepting groove of socket connector, maximum static friction force between them is converted into the body of plug terminal and the kinetic force of friction between female terminal, and the head of short plug terminal also begins to contact with female terminal, at this moment grafting process also needs to overcome the maximum static friction force between the two, and so continuation can be finished whole grafting process.
Owing to adopt such scheme, maximum static friction force in the grafting process between female terminal and plug terminal divides two stages to reach maximum, and according to theory analysis, maximum static friction force between them is greater than kinetic force of friction, mating force is evenly disperseed, the whole mating force that connects a process is reduced, and is improved the useful life of connector.
The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 6,7, the 8th, pin connector shown in Figure 5 and socket connector winding schematic diagram.
Please consult Fig. 2 earlier, this pin connector 1 comprises insulation shell 11 and several plug terminals 12,13 as shown in the figure, wherein an end is provided with plug surface 111 on the insulation shell 11, is provided with plurality of terminals accepting groove 112 (not shown) on plug surface again, is used to accommodate and locking-type plug terminal 12,13.And plug terminal 12,13 is fixed in the accepting groove 112 of insulation shell 11, and the length that is provided with of plug terminal 12 is lacked than 13, and the head 121,131 of two kinds of plug terminals 12,13 is taper, is beneficial to peg graft.In addition, socket connector 2 comprises insulation shell 21 and accepting groove 22, and wherein accepting groove 22 is located in the insulation shell 21, and female terminal 221 is installed in the accepting groove 22, after pin connector 1 and socket connector 2 grafting, female terminal 22 and plug terminal 12,13 promptly are electrically connected mutually.
As shown in Figure 3, because the plug terminal 12,13 of pin connector 1 has the branch of height, so, when pin connector 1 and socket connector 2 are connected with group, plug terminal 12,13 is divided into two stages with contacting of female terminal 221, wherein the phase I is that the head 131 of plug terminal 13 contacts with female terminal 221, and plug terminal 12 still can not come in contact with female terminal 221.Only be that the part plug terminal 13 of pin connector 1 contacts with female terminal 221 this moment, and the maximum static friction force that need overcome 221 of the head 131 of plug terminal 13 and female terminals can make plug terminal 13 enter the accepting groove 22 of socket connector 2.Continue the second stage of the application of force afterwards for pegging graft, plug terminal 12 also contacts with female terminal 221 as shown in Figure 3, but the head 131 of plug terminal 13 enters in the accepting groove 22 of socket connector 2 fully, only have its body 132 to contact with the conducting terminal 221 of socket connector 2, advancing the mating force of pin connector 1 and socket connector 2 this moment is the maximum static friction force sum of 22 of the head 131 of the kinetic force of friction of 22 of the body 132 of plug terminal 13 and female terminals and plug terminal 12 and female terminals.See also Fig. 4 again, at this moment the head 121,131 of the plug terminal 12,13 of pin connector 1 all enters in the accepting groove 22 of socket connector 2, and the kinetic force of friction sum that the power that only need apply again reaches 221 of the body 122,132 of plug terminal 12,13 and female terminals can make plug terminal 12,13 organize to go in the accepting groove 22 of socket connector 2 fully.According to result of theoretic analysis, the maximum static friction force that the head 121,131 of plug terminal 12,13 and female terminal are 221 is greater than the kinetic force of friction of 221 of the body 121,131 of plug terminal 12,13 and female terminals, because the head 121,131 of present embodiment plug terminal 12,13 reaches maximum with the stiction of 221 of female terminals respectively at phase I of pegging graft and second stage, make mating force evenly disperse and effectively reduced pin connector 1 and the mating force of 2 of socket connectors.
