Then, the assemble method of electric connector assembly 1 and the chimeric method of pin connector 10 and socket connector 40 are described.Figure 10 is presented at pin connector 10 and socket connector 40 when chimeric, the state that the 23a of corner portion of the protrusion 23 of pin connector 10 and circuit substrate PCB collide.
At first, the substrate connecting portion 64 with the plug contact 60 that constitutes socket connector 40 is welded on the circuit substrate PCB.Thus, socket connector 40 is installed on the circuit substrate PCB.
Then, as shown in Figure 2, insert through hole 25 from the electric wire of pin connector 10 end of 2 wire W is positioned on the electric wire connecting portion 32, with opening 22e the heart yearn W1 of these electric wires W is soldered to electric wire connecting portion 32 from welding.Then, the connector that the contact site 33 of wall portion 22, protrusion 23 and the plug contact 30 of pin connector 10 is inserted socket connector 40 as illustrated in fig. 1 holds in the recess 51.Thus, the card that the locking protrusion 24 of pin connector 10 is limited to socket connector 40 ends teat 55, and pin connector 10 is chimeric with socket connector 40.
If pin connector 10 is chimeric with socket connector 40, so, contact between the U-shaped shape two sides of each contact site 33 of plug contact 30 and the contact 63c of 1 pair of contact arm 63 of socket contact 60.Submounts that will be connected with electric wire W thus, and circuit substrate PCB are electrically connected.
At this, when between the contact 63c of each contact site 33 of plug contact 30 and socket contact 60, contacting, the 1 pair of contact arm 63 contact 63c place by about push expansion, simultaneously, be divided into the center and displacement downwards with the radicle that extends from base portion 62.That is, each contact 63c is pulled by contact site 33, and thus, 1 pair of contact arm 63 is divided into the center and displacement downwards with the radicle that extends from base portion 62.At this moment, the support portion 63b of each contact arm 63 contacts with the diapire 51a of Socket casing 50 and is supported.Thus, can prevent buckling of each contact arm 63.Especially, because support portion 63b is located at the position near contact 63c, thereby the distance between contact 63c and the support portion 63b is short, can prevent buckling between these contacts 63c and the support portion 63b exactly.
In addition, support portion 63b possesses from the bending part 63bb of extension, below 63ba that the front end of arm portion 63a extends downwards, the lower end edge horizontal direction bending of 63ba from the extension, below and from what bending part 63bb upwards erected and upwards erects part 6363bc.And 63b contacts with the diapire 51a of Socket casing 50 and when supported, the press surface of bending part 63bb is supported by diapire 51a in the support portion.Therefore, support portion 63b does not become the obstacle when carrying out that 1 pair of contact arm 63 pushed the action of expansion about contact 63c place.That is, when pushing of 1 pair of contact arm 63 expanded action, the press surface of bending part 63bb successfully moved on diapire 51a.In contrast, supported by diapire 51a if support portion 63bb processes the shear surface that is caused at the stamping-out of metallic plate, then the expansion action of pushing to 1 pair of contact arm 63 brings obstacle.
In addition, shown in figure 10 with pin connector 10 and socket connector 40 when chimeric, the connector that sometimes pin connector 10 is inserted socket connector 40 obliquely holds recess 51.If pin connector 10 is inserted obliquely, then the 23a of corner portion of the protrusion 23 of pin connector 10 sometimes collides with circuit substrate PCB.This be because, the diapire 51a for low level at Socket casing 50 is formed with through hole 56, the 23a of this corner portion is sometimes through this through hole 56.In this case, because the 23a of this corner portion forms by insulating material, thereby the metallic plug contact 30 that can avoid pin connector 10 sides is with respect to the circuit on the circuit substrate PCB and the possibility of short circuit.That is, because protrusion 23 is formed by insulating material, the outermost corner portion of the contact site 33 of plug contact 30 is formed with otch 33a with the mode that is covered by the insulating material of protrusion 23 (23a of this corner portion).
In contrast, under the situation of the electric connector shown in Figure 12 200 shown in the prior art, the enhancing protrusions 228 of socket contact 224 is outstanding towards circuit substrate PCB from the opening 223 that is formed at Socket casing 221, is connected to circuit substrate PCB.Therefore, be formed under the situation on the circuit substrate PCB under the opening 223, might be short-circuited etc. at circuit.
And, under the situation of the electric connector assembly 1 of this execution mode, be formed with opening 65 at the base portion 62 of socket contact 60.And, at Socket casing 50, be provided with the projection 53 that gets into opening 65 and support socket contact 60.Constitute through possessing these, thereby play 3 following effects.
At first, the first, with pin connector 10 during from socket connector 40 dismounting, the masterpiece that pulls to the top is used for socket contact 60, and excessive masterpiece is used for fixing portion 61 and substrate connecting portion 64.At this moment, because the projection 53 of Socket casing 50 supports socket contact 60, thereby can reduce the power that acts on these fixed parts 61 and substrate connecting portion 64.Especially, because opening 65 is located at base portion 62 with the mode of crossing over substrate connecting portion 64, thereby the position of projection 53 is near the substrate connecting portion 64 that is soldered.Therefore, it is big to act on the reduction effect of power of substrate connecting portion 64.
The second, through projection 53 is set, thereby can improve the mechanical strength of Socket casing 50 self.
The 3rd, through projection 53 is set, near the base portion 62 substrate connecting portion 64 forms opening 65, thereby owing to opening 65 works as the scolder place of accumulating, thereby can prevent that scolder from rising.
More than, execution mode of the present invention has been described, but has been the invention is not restricted to this, can carry out various changes, improvement.
For example, plug contact 30 respectively is provided with 2 with socket contact 60, but quantity is not limited thereto, and also can be 1, also can be more than 3.
In addition, not necessarily must protrusion 23 be set in the tabular portion 21 of plug casing 20, in addition, the contact site 33 of plug contact 30 also can not necessarily form and cover protrusion 23 with the U-shaped sigmoid.
And, in the situation etc. that does not form through hole 56 at the diapire 51a of Socket casing 50 down, not necessarily must form otch 33a with the mode that is covered by the insulating material of protrusion 23 in the outermost corner of the contact site 33 of plug contact 30 one.
In addition, at contact arm 63, under the situation that contact arm 63 can not be buckled, not necessarily support portion 63b must be set.In addition,, also be not limited to shape shown in Figure 9, the shape that promptly possesses below extension 63ba, bending part 63bb and upwards erect part 63ba even under the situation that is provided with support portion 63b.
In addition, not necessarily must form opening 65, in addition, not necessarily must projection 53 be set at Socket casing 50 at socket contact 60.
And, be formed with recess 52 at the end face of Socket casing 50, but also can make the height of end face all become the height of the bottom surface of recess 52.That is, also can there be the stage portion of dividing recess 52.
