Connector 1 such above, make the stator 6c of movable conducting terminal 6 press-in be fixed on the holddown groove 5a1 of movable housing 5 and make stator 6a2 be pressed into the holddown groove 4b1 being fixed on stationary housing 4, make the stator 7a of contact terminal 7 be pressed into the holddown groove 5a2 being fixed on movable housing 5 in the lump.
Now, be formed as about movable conducting terminal 6,7 movable conducting terminals 6, afterbody 6a1 side is same spacing relative to the bracket (omit diagram) of copper alloy terminal material with 7 retracting portion 5a of movable housing 5.Namely, the movable conducting terminal 6 of present embodiment with contact with terminal 7, the contact site 20b of the clip configuration in the past shown in Figure 29 is not all had to need like that along spacing direction cutting material and the structure part above launched at spacing direction (X-direction), so bracket can be formed at the thin space identical with retracting portion 5a.They can be pressed into together in the present embodiment and be fixed on stationary housing 4 and movable housing 5, thus reduce manufacturing cost.Contact terminal 7 also similarly can be formed with the thin space identical with retracting portion 5a relative to the bracket (omit and illustrate) of stainless steel alloy terminal material with movable conducting terminal 6, they can be pressed into together fixing thus reduce manufacturing cost.
Then, by last by standing finish 9 press-in be fixed on stationary housing 4 holddown groove 4d3 thus can assembly and connection device 1.Connector 1 after this assembling, the outer surface of movable housing 4 from the suspended state that the retracting portion 5a of stationary housing 5 leaves only by 7 movable conducting terminal 6 resiliency supported (Figure 14).
(using method of connector 1)
Next, method electric component 8 being connected to by use connector 1 to the circuit of substrate P is described.
before connection (Figure 13,14)
Connector 1 is by installing foot's 9b solder of afterbody 6a1 and standing finish 9 on surface in substrate P.And, as shown in Figure 13, Figure 14, from the below of substrate P, the terminal 8a of electric component 8 is inserted connector 1.
during the insertion of terminal (Figure 14, Figure 15)
First, if terminal 8a is inserted connector 1, then first terminal 8a passes through the hole P1 of substrate P, then passes through the patchhole 4c1 of stationary housing 4.Now, even if the insertion axle of terminal 8a is relative to the hole axle dislocation of inserting hole 4c1, owing to being formed with the conical surface at inserting hole 4c1, so also terminal 8a can be inserted smoothly.The situation that the insertion axle of so-called terminal 8a and hole axle misplace, produces when the forming position of the hole P1 of such as substrate P and/or the installation site of connector 1 misplace slightly.In addition, also can produce when staggering in the insertion position of substrate P and electric component 8.Such dislocation can all be eliminated by patchhole 4c1.
Next, terminal 8a enters the patchhole 5d1 of movable housing 5.Now, even if the insertion axle of terminal 8a is relative to the hole axle dislocation of patchhole 5d1, owing to being formed with the conical surface at inserting hole 5d1, so also terminal 8a can be inserted smoothly.Insertion axle in this situation and the dislocation of hole axle, further, at the assembling position of the movable housing 5 be only elastically supported relative to stationary housing 4 with movable conducting terminal 6 because also producing certain reason misplaces.Therefore, the exterior side bore edges of patchhole 5d1 compared with the inner face side bore edges of the patchhole 4c1 of adjacent stationary housing 4 formation larger.Thus, even if patchhole 4c1 is relative to the dislocation of hole axle, also terminal 8a can be inserted among movable housing 5 smoothly.
during the contact of terminal (Figure 15, Figure 16)
Enter the terminal 8a of the contact chamber 5a3 of the retracting portion 5a of movable housing 5, next contact with movable conducting terminal 6.Now, terminal 8a with the lower lateral bend 6d1 of movable conducting terminal 6 and rake 6d8 at least any one is " guiding inclined plane " and sliding contact, insert between the first contact portion 6d2 and the second contact portion 6d7.
The elastic contact part 6d of movable conducting terminal 6 is retractd in the inside of contact chamber 5a3 in cantilever manner with the elastic contact part 7b contacted with terminal 7.Under this retracting state, if the first contact portion 6d2 and the second contact portion 6d7 staggers from Standard contact position on fore-and-aft direction Y, the lower lateral bend 6d1 of movable conducting terminal 6 and rake 6d8 also can be utilized positively to be inserted by terminal 8a.
In addition, as the lower lateral bend 6d1 of the movable conducting terminal 6 on " guiding inclined plane " and rake 6d8 relative to the inclination angle of the insertion axle of terminal 8a, acute angle is in a ratio of with the inclination angle of the conical surface of patchhole 5d1.Therefore, it is possible to guide terminal 8a makes the contact position of its direction of insertion along terminal 8a periodically to standard close.
And if terminal 8a former state inserted, then the second contact portion 6d7 of movable conducting terminal 6 is opened by side pressure forward, thus the lower end side that sheet portion 6d5 is indulged in support chip portion 6d9 and front side contacts relative to pressure contact portion 7b4.The face contact power produced by the pressure contact portion 7b4 of contact terminal 7 acts on terminal 8a as Cat-in resisting force via the second contact portion 6d7.If continued to insert by terminal 8a under the state being subject to this Cat-in resisting force, then movable housing 4 displacement is until the movable projection 5c of side and the stopper portions 9a apical grafting of standing finish 9.And if in this condition terminal 8a is inserted into predetermined intubating length, then electric component 8 has connected (Figure 16) relative to the conducting of the contact position of the standard of connector 1 before movable.In addition, the fixture 10 that the mobile restriction of movable housing 4 when terminal 8a inserts also can utilize pressing plate such.In addition, the predetermined intubating length of terminal 8a is the length of the predetermined effectively chimeric length that can obtain terminal 8a, this length can be inserted until apical grafting adjusts in the back side of substrate P by such as electric component 8, or adjusts by using the insertion fixture of electric component 8.
the work (Figure 16) of connector 1
The contact position conducting of the standard that Figure 16 is terminal 8a before movable is connected to the state of connector 1, and the contact condition of terminal 8a and movable conducting terminal 6 is by realizing by contacting the face contact power produced with terminal 7.If apply vibration to connector 1 in this condition, then movable housing 5 by the movable plate 6b of movable conducting terminal 6 relative to stationary housing 4 in the scope of clearance D 1 ~ D3 elastic displacement to absorb vibration.Meanwhile, the electric component 8 maintaining terminal 8a also elastic displacement to absorb vibration.
