In addition, shown in Fig. 3 (c),,, be provided with open with the rear respectively earth connection recess 15 downwards in each one that becomes the upside that imports otch 23b in the back of lid 1b.And, be inserted into earth connection with in the recess 15 by front portion, thereby can make the anticreep projection 23c earth connection EC that nips improve maintenance intensity in anterior farther position from earth connection EC with earth connection EC.
In addition, as shown in figure 11, approach the inner surface of the opposing party's earth connection in about earth connection is with recess 15 with a side of recess 15, near open lower side, form towards the below, to increasing the inclined plane 15a that the direction of earth connection with the opening of recess 15 tilts, earth connection EC is guided shown in the arrow A 3 of Figure 11 like that by this inclined plane 15a, and earth connection EC is more prone to be imported into earth connection with in the recess 15 thus.
According to said structure, owing to import otch 23b by on packing ring 23, being provided with, make the distance of anticreep projection 23c of the lower end of packing ring 23 and upside shorten, therefore, by earth connection EC is imported to the downside of packing ring 23 through importing otch 23b, can make the anticreep projection 23c earth connection EC that easily nips.In addition, import otch 23b owing to utilize, can make earth connection EC is imported the position of downside of packing ring 23 more by upside, so by further increasing the width dimensions up and down of spigot surface 12c, make to tilt to be tending towards and relax, the bending of earth connection EC in the time of can reducing the downside that imports packing ring 23 reduces to insert needed power, thereby can carry out the connection of earth connection EC to earth terminal 2 more easily.
, the earth terminal 2 of present embodiment as shown in figure 12, can also be connected in the Y shape crimp type terminal YT that is made of metallic plate, have otch YT1.For such Y shape crimp type terminal YT is connected with earth terminal 2, Y shape crimp type terminal YT is imported between packing ring 23 and the earth terminal daughter board 21, and the otch YT1 of Y shape crimp type terminal YT is imported to the stubborn 22a of portion that closes of terminal screw 22, and fastening then terminal screw 22 gets final product.And,,, be provided with the open up and down importing recess 16 that is communicated with terminal housing recess 12 in the front of lid 1b at the downside of terminal screw 22.Import recess 16 about the size of size about greater than above-mentioned Y shape crimp type terminal YT, by Y shape crimp type terminal YT is imported through importing recess 16, Y shape crimp type terminal YT easily can be connected with earth terminal 2.
And, also can make the size of small diameter part 22c, greater than the total of the gauge of the gauge of packing ring 23 and Y shape crimp type terminal YT at direction of principal axis (fore-and-aft direction).If adopt this structure, then as shown in figure 13, since can be between the head 22b of packing ring 23 and terminal screw 22 clamping Y shape crimp type terminal YT, so compare with the situation that Y shape crimp type terminal YT need be imported to the rear side of packing ring 23, the connection of Y shape crimp type terminal YT is more easy.
In addition, downside at the importing otch 23b of packing ring 23, also can replace anticreep projection 23d being set by bending rearward, but as Figure 14 (a) and shown in Figure 15, (top of Figure 15) perk is provided with by forwards: the back is towards the top (Figure 15's is right-hand) of the depth direction that imports otch 23b and the introduction part 23e of tilted rearward.If adopt this structure, then since the back that earth connection EC is imported into the 23e of portion be directed between packing ring 23 and the earth terminal daughter board 21, so earth connection EC is more easy to the connection of earth terminal 2.In addition, at Figure 14 (a) (b) and in the example of Figure 15, by changing the shape of packing ring 23, make on the anticreep projection 23c, the back towards above and the scope of tilted rearward is further elongated on above-below direction, give anticreep projection 23c function thus, so that earth connection EC becomes the mode at oblique rear to earth connection EC channeling conduct with respect to the front of shell 1 as guide portion.In addition, shown in Figure 14 (b), on earth terminal daughter board 21, rearward outstandingly respectively from the both ends, the left and right sides of main part 21b be provided with rake 21j, the front of this rake 21j is relative with the back of anticreep projection 23c, and towards the top and tilted rearward.Earth connection EC is guided by the back of anticreep projection 23c, and become oblique rear with respect to the front of shell 1, thus, becoming parallel situation with earth connection EC with respect to the front of shell 1 compares, because by the more earth connection EC of clamping between earth terminal daughter board 21 and packing ring 23, so can improve the confining force of 2 couples of earth connection EC of earth terminal.In addition, by on earth terminal daughter board 21, being provided with rake 21j,, thereby improved connection reliability owing to the contact area increase of earth terminal daughter board 21 and earth connection EC.
