In addition, crossbeam 23 is for become the curved configuration body of protruding mode bending with front surface, thereby only for the situation of the planar configuration body of plane, compare with the front surface that makes crossbeam can enhance mechanical strength.
Moreover crossbeam 23 is arranged on the roughly front end of 1 the 1st contact 21 of pars intermedia that is configured in a plurality of contacts 21 that configured side by side.Therefore,, when a plurality of the 1st contacts 21 insertions are taken shape in to housing 10, the balance the 1st contact 21 and column direction position that crossbeam 23 is set is good, can guarantee the positional stability of a plurality of the 1st contacts 21.
The 1st variation of crossbeam 23 then, is described with reference to Figure 17 to Figure 19.In Figure 17 to Figure 19, for the parts identical with Figure 11 to Figure 13, give identical symbol, sometimes the description thereof will be omitted.
In Figure 17 to Figure 19, the roughly pars intermedia in a plurality of the 1st contacts 21 that configured side by side, specifically, at the front end of the 3rd the 1st contact 21 from left side, is provided with the crossbeam 23 extending along the left and right directions that is orthogonal to fore-and-aft direction.This crossbeam 23 is different from the crossbeam 23 shown in Figure 11 to Figure 13, via following surface the front end of the 21c of top contact portion from the 1st contact 21, becomes the link sheet 23a of protruding mode bending and extends.Crossbeam 23 is by forming from linking the rectangular-shaped clava in cross section of the front end edge left and right directions extension of sheet 23a.And crossbeam 23 is metal systems, form as one together with the 1st contact 21.In addition, the mode that crossbeam 23 exposes with front surface is embedded in protuberance 12.
Even in the situation that such crossbeam 23 is arranged to the front end of the 1st contact 21, when matching connector 50 is chimeric obliquely with respect to electric connector 1, the cover 80 of matching connector 50 also with the front surface collision of crossbeam 23.Therefore, avoid top (front end) breakage of protuberance 12.
In addition, matching connector 50 is chimeric obliquely with respect to electric connector 1, moreover, even matching connector 50 slides and in reciprocating situation, the cover 80 of matching connector 50 also slides with respect to the front surface of crossbeam 23 along left and right directions.Therefore, protuberance 12 can be not damaged.
The 2nd variation of crossbeam 23 is described with reference to Figure 20 to Figure 22 in addition.In Figure 20 to Figure 22, for the parts identical with Figure 11 to Figure 13, give identical symbol, sometimes the description thereof will be omitted.
In Figure 20 to Figure 22, crossbeam 23 is different from shown in Figure 11 to Figure 13, is configured to link the front end of 2 the 1st contacts 21 of the outermost end in a plurality of the 1st contacts 21 configured side by side.This crossbeam 23 is with front surface, to become protruding mode curved configuration body crooked and that extend downwards from the front end of the 21c of top contact portion of 2 the 1st contacts 21 of outermost end.Crossbeam 23 is metal systems, forms as one with together with 2 the 1st contacts 21 of outermost end.The mode that this crossbeam 23 exposes with front surface is embedded in protuberance 12.
Even in the situation that such crossbeam 23 is arranged to the front end of the 1st contact 21, when matching connector 50 is chimeric obliquely with respect to electric connector 1, the cover 80 of matching connector 50 also with the front surface collision of crossbeam 23.Therefore, avoid top (front end) breakage of protuberance 12.
In addition, matching connector 50 is chimeric obliquely with respect to electric connector 1, moreover, even slide and in reciprocating situation, the cover 80 of matching connector 50 also slides with respect to the front surface of crossbeam 23 along left and right directions at matching connector 50.Therefore, protuberance 12 can be not damaged.
In addition, crossbeam 23 is configured to link the front end of 2 the 1st contacts 21 of the outermost end in a plurality of the 1st contacts 21 configured side by side.Therefore, a plurality of the 1st contacts 21 are being inserted while taking shape in housing 10, the support of crossbeam 23 becomes stable because of 2 the 1st contacts 21 of outermost end.Thus, can maintain higher the positional stability of a plurality of the 1st contacts 21.
Above, embodiments of the present invention have been described, but have the invention is not restricted to this, can carry out various changes, improvement.
For example, crossbeam 23 needn't be located at the front end of the 1st contact 21, also can be located at the front end of the 2nd contact 22.
In addition, crossbeam 23 needn't be for becoming the rectangular-shaped clava of curved configuration body or cross section of protruding mode bending with front surface, if extended along the left and right directions with fore-and-aft direction quadrature, the mode of exposing with front surface is embedded in protuberance, can be so also any shape.
Moreover, crossbeam 23 also needn't be arranged at the roughly front end of 1 the 1st contact 21 of pars intermedia that is configured in a plurality of the 1st contacts 21 that configured side by side, also can be arranged on the front end of 2 the 1st above contacts 21, or be arranged at the front end of outmost the 1st contact 21.
In addition, crossbeam needs not to be metal system, in addition, also needn't form as one together with the 1st contact 21.
