(with reference to Fig. 1) as can be known when observing from the top, the upper end of sidewall 12 is curved. in more detail, the upper end of two side 12 begins to insert oral-lateral near the convex contact more from contact site 12x, the inside and outside two sides of y direction are big more at interval, begin more A direction end near enlarged portion 12b from contact site 12x, the inside and outside two sides of y direction are also big more at interval.Particularly carry out chamfer machining near the upper end of the convex contact of sidewall 12 insertion oral-lateral, made wall thickness diminish.
Conductor pressure contact portion 20 and insulator pressure contact portion 30 are as Fig. 1~shown in Figure 3, all form the U font that the top is opened wide. when using concave contactor 1, conductor pressure contact portion 20 and insulator pressure contact portion 30 be as Fig. 5 (A) and shown in Figure 6, respectively the conductor 51 of electric wire 50 and insulator sheath 52 carried out crimping and fix.
Then, with reference to Fig. 5 (A), Fig. 5 (B) and Fig. 6, the state that concave contactor 1 is contained in the state in the housing 40 and takes in convex contact 100 in concave contactor 1 describes.In the present embodiment, housing 40 holds 3 concave contactors 1.In Fig. 5 (A) and Fig. 6, only the concave contactor 1 of paper inboard to be annotated with symbol, 2 concave contactors 1 of other paper nearside are identical with it, the Therefore, omited symbol.
At first, the formation to housing 40 describes. and shown in Fig. 5 (A), housing 40 has 3 roughly rectangular-shaped concave contactor accommodating chambers 41 that are used to hold concave contactor 1.Each concave contactor accommodating chamber 41 extends on the x direction, at x direction one end opening that is positioned at Fig. 5 (A) left side of housing 40.Can be that front end inserts concave contactor 1 from this opening with socket 10, and, after having held concave contactor 1, will be drawn out to the outside by conductor pressure contact portion 20 and the fixing lead 50 of insulator pressure contact portion 30 crimping.Near housing 40 end faces of this opening, its periphery is cut off a part, thereby has increased aperture area.
On the other hand, on the x direction other end on the right side that is positioned at Fig. 5 (A) of housing 40, being formed with 3 convex contacts in the mode that is communicated with each concave contactor accommodating chamber 41 inserts mouthful 45. convex contacts and inserts mouthfuls 45 and have similar to the cross section of convex contact 100 but than its big some shape, and, same with above-mentioned opening, be cut off a part near housing 40 end faces of convex contact insertion mouth 45, increased aperture area, so that can plug convex contact 100 (with reference to Fig. 6).
Each concave contactor accommodating chamber 41 has the cross section shape shown in Fig. 5 (B) at the part place that keeps socket 10.In more detail, concave contactor accommodating chamber 41 has wide cut space 41a that is formed at the bottom and the 41b of space in a narrow margin that is formed at top.Wide cut space 41a and in a narrow margin the width of space 41b (being the length of y direction) respectively with D
oNear 1 (lateral surface of part on the y direction at interval two side main body 12a and connecting portion diapire 11) and D
o2 (two enlarged portion 12b on the y direction lateral surface at interval) are about equally. in housing 40, formed ladder by different space 41a, the 41b of such width. and wide cut space 41a and the height of space 41b (being the length of z direction) is roughly the same in a narrow margin, both sums are more some greatly than the height of socket 10.
Under concave contactor 1 is contained in state in the accommodating chamber 41, the diapire 11 of socket 10 is by the housing 40 inwalls supporting of the bottom that is positioned at wide cut space 41a, basically contact with housing 40 inwalls of 41a both sides, wide cut space near among the sidewall body 12a and connecting portion diapire 11. thus, the bottom of socket 10 stably remains in the concave contactor accommodating chamber 41. on the other hand, on the top of socket 10, enlarged portion 12b contacts basically with housing 40 inwalls of space 41b both sides in a narrow margin.
The convex contact 100 that electrically contacts with concave contactor 1 as shown in Figure 6, card ends on housing 140 in advance. be accompanied by housing 40 then, engaging operation between 140, two connectors 1 have been realized, electric contact between 100. in more detail, the convex contact is engaged with housing 40 with concave contactor with housing 140, make the convex contact cover concave contactor housing 40 with housing 140, with its concomitantly, each convex contact 100 inserts mouth 45 by the convex contact of housing 40 successively, between the sidewall body 12a of the socket 10 of concave contactor 1, and then contact with contact site 12x and contact site 12x is pushed open laterally and inserts, like this, housing 40, engaging between 140 has just been finished. at this moment, convex contact 100 is by elastic force that contact site 12x gave and be fixed on reliably in the socket 10, but conducting ground keeps under the contact pressure of regulation. thus, and two connectors 1, guaranteed good electric contact between 100.On the other hand, enlarged portion 12b contactlessly keeps apart with convex contact 100 this moment.
As previously discussed, concave contactor 1 according to present embodiment, in concave contactor 1 is contained in the housing 40, shown in Fig. 5 (B), near the diapire 11 of socket 10 and sidewall body 12a and connecting portion diapire 11, enlarged portion 12b also contacts basically with housing 40. like this, the top of socket 10 and two places, bottom all with situation that housing 40 contacts basically under, as shown in Figure 6, even the convex contact 100 in the accommodation space that is accommodated in socket 10, perhaps be connected on the electric wire 50 on the concave contactor 1 and apply external force, and on concave contactor 1, apply the power of its cross section direction therefrom, can prevent that also the side of concave contactor 1 in housing 40 from falling.That is,, concave contactor 1 stably can be remained in the housing 40 according to the formation of present embodiment.
In addition, the enlarged portion 12b of present embodiment is located at the x terminad of sidewall 12 as shown in Figures 1 and 2. according to this formation, when on sidewall 12, forming enlarged portion 12b, as long as its x direction end is pushed open laterally, can form enlarged portion 12b with suitable utensil fairly simplely.
The contact site 12x and the enlarged portion 12b that are formed on the sidewall 12 set gradually along the A direction. in addition, convex contact by oppose side wall 12 carries out chamfer machining near inserting the upper end of oral-lateral, as shown in Figure 1, the mutual medial surface of sidewall 12 upper ends on the y direction at interval, insert the porch greatly at the convex contact than contact site 12x place. therefore, its front end and sidewall butt when being inserted into convex contact 100 in the socket 10 can be prevented, thereby the insertion operation of convex contact 100 can be successfully carried out.Promptly, bigger by the sidewall 12 medial surfaces interval that makes the slotting porch of convex contact than the width W of convex contact 100, make and be easy to insert convex contact 100, and it is little that sidewall 12 medial surfaces at the contact site 12x place by making A direction downstream are inserted the porch than above-mentioned convex contact at interval, can give elastic force ground to convex contact 100 and carry out clamping, thereby can improve connection reliability with convex contact 100 it.
In addition, as shown in Figures 3 and 4, socket 10 is when observing from the cross section, and is elongated on the z direction.That is, the sidewall 12 of socket 10 is smaller along the length of y direction, so the implementation space is saved effectively.Although and then constituting as this, under the elongated situation in the cross section of socket 10, be difficult to guarantee the stability of concave contactor 1 in housing 40, above-mentioned side Inverse problem becomes remarkable, but in the present embodiment, even under such situation, also can prevent concave contactor 1 sidelong the side of profile direction fall, thereby can stably keep concave contactor.
More than, a preferred embodiment of the present invention is illustrated, but the present invention is not limited to above-mentioned execution mode, can do various design alterations within the scope of the claims.Especially, can consider following change.
Socket 10 can not be elongated on the z direction when the cross section is observed.
And, enlarged portion 12b can not be arranged on the x direction end of sidewall 12, contact site 12x and enlarged portion 12b set gradually along the A direction. promptly, enlarged portion 12b is so long as get final product near being positioned at the upper end of sidewall 12, the not special restriction in its position on the x direction. for example, can form enlarged portion 12b by near convex contact insertion mouth, making sidewall 12 expansion outside the y direction, can also form enlarged portion 12b by making near outside the y direction, the expansion in its upper end near the z direction central authorities that contact site 12x are located at sidewall.
In the above-described embodiment, in order successfully to carry out the insertion operation of convex contact 100, and make the mutual medial surface of upper end on the y direction of sidewall 12 insert the porch greatly at the convex contact at interval than contact site 12x place, but be not limited to this, also can make the above-mentioned medial surface of the slotting porch of convex contact roughly the same with the width W of connector 100 at interval.
The shape of convex contact 100 is not limited to tabular, also can be the pin shape. then, can be in the scope that does not break away from purport of the present invention, with the shape of convex contact 100 correspondingly, the shape, the particularly shape of socket 10 of suitable change concave contactor 1.
Each one to concave contactor 1 is illustrated by 1 dull and stereotyped situation about forming, but is not limited to this, and for example also can make the lance shape 11a of portion is miscellaneous part. and each one of concave contactor 1 is not limited to be made of same material, also can be made of different materials.
