Fig. 9 is the figure that observes the connector cable socket 10 under the secondary fastening state from side 53 sides of connector shell 50.Manifest medial surface 31b and the end face 31c of metal sleeve 22, first alar part 31, medial surface 33b and end face 33c, the side 58a of base portion 58 and the side 59a of base portion 59 of flap portion 33 from window portion 55.The operator who carries out secondary fastening operation is through visuognosis medial surface 31b and end face 31c and medial surface 33b and end face 33c, thereby can learn easily that connector cable socket 10 is secondary fastening states.Have, though not shown, the operator who carries out secondary fastening operation can also be from the medial surface 32b of window portion 56 visuognosiss, second alar part 32 of window portion 55 opposition sides and the medial surface 34b and the end face 34c of end face 32c and the 4th alar part 34 again.
Here; If for example with medial surface 33b and end face 33c with the color separation in advance of mutually different color; Surface state (surface state), surface roughness (the thick さ of face) that perhaps makes medial surface 33b and end face 33c etc. is different and can discern by reflection of light, and then the operator can learn more easily that connector cable socket 10 is secondary fastening states.
Secondly, the assembling procedure to connector cable socket 10 describes.
At first, the metal shell 30 with outer casing sleeve crimp body 20 is inserted in the patchhole 51 along each self-corresponding gathering sill 61~64 ground to make first alar part 31~the 4th alar part 34.When metal shell 30 arrived fastening spaces 57, then metal shell 30 fastenings were on fastening wall 67.At this moment, thus the operator of hand-held housing sleeve crimp body 20 falls into from each guide wall of gathering sill 61~64 through first alar part 31~the 4th alar part 34 and obtains click effect, therefore can recognize a fastening clearly and finish.
Secondly, secondary fastening operation is described.Shown in Figure 10 (a), in secondary fastening operation, use a pair of anchor clamps 70 that insert in window portion 55 and 56.The anchor clamps 70 that insert in the window portion 55 have the contact site 71 and 73 that is formed by curved surface.The anchor clamps 70 that are inserted in the window portion 56 have the contact site 72 and 74 that is formed by curved surface.Contact site 71~74 is respectively with first alar part 31~the 4th alar part 34 bendings.
At window portion 55 and 56 configuration anchor clamps 70; Anchor clamps 70 are inserted into the position shown in Figure 10 (b); With first alar part 31 and second alar part 32 by the side that is pressed in base portion 58, flap portion 33 and the 4th alar part 34 by after the ground bending on the side that is pressed in base portion 59, are extracted anchor clamps 70.Its result, shown in Figure 10 (c), first alar part 31~the secondary fastening is last at secondary fastening wall 68a~68d respectively for the 4th alar part 34.
As stated, constituting of the connector cable socket 10 that this execution mode relates to possesses: first alar part 31~the 4th alar part 34 that is formed at metal shell 30; Carry out a fastening wall of a fastening in the fastening space 57 on being formed at connector shell 50; With first alar part 31 after the bending~the 4th alar part 34 is carried out the secondary fastening wall of secondary fastening, so can realize the raising of fastening intensity.According to the comparative result of fastening intensity, be the fastening intensity of resinous existing connector with respect to retainer etc., because the connector cable socket 10 that this execution mode relates to has above-mentioned formation, so can obtain the fastening intensity more than 2 times.
In addition, the connector cable socket 10 that this execution mode relates to not need as the retainer of existing connector etc. establish parts in addition, therefore can realize the minimizing of number of components, and can be than existing connector reduction manufacturing cost.
Secondly, the variation of above-mentioned alar part is described with reference to Figure 11 and Figure 12.Figure 11 and Figure 12 are the figure of the variation of expression metal shell 30 shown in Figure 3.
In the above-described embodiment, shown in the figure of upper strata central authorities of Fig. 3, first alar part 31 and flap portion 33 are arranged on the same position with respect to the direction of insertion of metal shell 30.In addition, shown in lower map among Fig. 3, flap portion 33 and the 4th alar part 34 are arranged on the same position with respect to the direction of insertion of metal shell 30.
Relative with it, the metal shell 30 shown in Figure 11 (a) is provided with alar part 81 in the position different with the position of first alar part 31 as flap portion with respect to direction of insertion.In addition, the metal shell 30 shown in Figure 11 (b) is provided with alar part 82 in the position different with the position of the 4th alar part 34 as flap portion with respect to direction of insertion.
In addition, in the above-described embodiment, shown in the right at the middle and upper levels figure of Fig. 3, the alar part that the present invention relates to is made up of four first alar parts 31~the 4th alar part 34.
Relative with it, can also constitute the alar part that the present invention relates to as illustrated in fig. 12.That is, the metal shell 30 shown in Figure 12 (a) has on the tangential direction of metal shell 30 outstanding two alar parts 83 and 84.In addition, the metal shell 30 shown in Figure 12 (b) has in the footpath of metal shell 30 upwards outstanding two alar parts 85 and 86.In addition, the metal shell 30 shown in Figure 12 (c) has three upwards outstanding alar parts 87~89 in the footpath of metal shell 30.
If as one man form a fastening wall, secondary fastening wall and the base portion of connector shell with the shape of Figure 11 and alar part 81~89 shown in Figure 12 and position etc., then can carry out a fastening and secondary fastening to alar part 81~89.
Utilizability on the industry
As stated; Connector that the present invention relates to and assemble method thereof have the effect of the minimizing of the raising that can realize fastening intensity and number of components, and are useful as connector and the assemble method thereof that the fastening through two sections of metal shell and connector shell fixes will be set at an end of coaxial cable.
