If be provided with sealing gasket 3 between the outside of the first cavity 101 outer walls of the connector for electronic detonators that embodiment 1 provides and the inner side of the second cavity 201 outer walls, as shown in Figure 7, the gap between the first cavity 101 outer walls and the second cavity 201 outer walls not only has the function that prevents conductive impurity, rainwater and sweat, also has the function of degree of depth waterproof.Although connector for electronic detonators is fallen in the puddle of 30 centimetres of the depth of waters, water also cannot enter the second cavity 201 from the gap between the first cavity 101 outer walls and the second cavity 201 outer walls, and then cannot have influence on the fastening place of metal snap-fastener.
The structure that above-described embodiment 1 provides can also be improved.As shown in Fig. 8 (a), the protuberance 108 around the first cavity 101 outer walls is set at the middle part of the first cavity 101 outer walls, and the second cavity 201 outer walls are divided into inside and outside two-layerly, inner layer outer wall 210 is shorter than outer outer wall 211.And when 2 metal snap-fasteners 104 that are fixed on the first cavity 101 bottom outside respectively with the dividing plate 204 being fixed in the second cavity 201 on 2 metal snap-fasteners 207 while fastening, the top of the bottom of the protuberance 108 of the first cavity 101 outer walls and the inner layer outer wall 210 of the second cavity 201 is closely pressing just in time, as shown in Fig. 8 (b).The inner layer outer wall 210 of the second cavity 201 equals the thickness around the protuberance 108 of the first cavity 101 outer walls with the difference in height of outer outer wall 211.Now, the top around the protuberance 108 of the first cavity 101 outer walls flushes with the top of outer outer wall 211.This structure, in the situation that the top of the first cavity 101 outer walls does not arrange outer, has also reached the effect in the gap between shutoff the first cavity 101 outer walls and the second cavity 201 outer walls, and then prevents almost whole conductive impurities, rainwater and sweat.
In electric detonator installation process, if enforcement personnel touch electric detonator electric wire connecting junction because of carelessness, likely the first connecting portion 1 snapping together and the second connecting portion 2 are dragged out.For the first connecting portion 1 and the second connecting portion 2 that make to snap together are more firm, embodiment 4 can also be further improved.As shown in Fig. 9 (a), at the top of the outer outer wall 211 of the second cavity 201,2 symmetrical elastic protrusions 212 are set, on each elastic protrusion 212, arrange 1 to the interior side-prominent flange 213 of outer outer wall 211.When 2 metal snap-fasteners 104 that are fixed on the first cavity 101 bottom outside are respectively when being fixed on 2 metal snap-fasteners 207 on dividing plate 204 and fastening, the bottom of this flange 213 is just pressed in the top of the protuberance 108 of the first cavity 101 outer walls, as shown in Fig. 9 (b).The advantage of this structure is, after the first connecting portion 1 and the second connecting portion 2 fasten, flange 213 has been pushed down the protuberance 108 of the first cavity 101 outer walls, therefore can only pass through larger power, the first cavity 101 could be extracted out in accommodating cavity 202 from the second cavity 201.This makes the first connecting portion 1 and the second connecting portion 2 after fastening be difficult for throwing off.
As shown in Figure 10 (a), flange 213 adopts semicircular shape.This flange 213 is convenient to installation and removal.When mounted, when when pressing down the first cavity 101, the protuberance 108 of the first cavity 101 outer walls can glide in supreme accommodating cavity 202 along the first half of semicircular flanges 213.Otherwise when dismounting, when upwards drawing the first cavity 101, the protuberance 108 of the first cavity 101 outer walls can skid off upper accommodating cavity 202 in the Lower Half of semicircular flanges 213.Because semicircular flanges 213 is arranged on elastic protrusion 212, therefore the protuberance 108 of the first cavity 101 outer walls can stretch because of the elasticity of self automatically laterally in downward or the process Elastic projection 212 that moves up, thereby makes the first cavity 101 enter smoothly or take out accommodating cavity 202.
As shown in Figure 10 (b), flange 213 can also adopt take the inwall of elastic protrusion 212 and the right angled triangle that flange 213 bottoms are right-angle side.This flange 213 is convenient to install, and operation is more complicated during dismounting.When mounted, when when pressing down the first cavity 101, the protuberance 108 of the first cavity 101 outer walls can glide in supreme accommodating cavity 202 along the hypotenuse of right angled triangle.In when dismounting, need firmly elastic protrusion 212, to extrapolation, when the bottom of flange 213 is not pressed in protuberance 108 top of the first cavity 101 outer walls, just the first cavity 101 to be taken out from upper accommodating cavity 202.This structure makes the first connecting portion 1 and the second connecting portion 2 after fastening more be difficult for throwing off.
In order to make the structure of embodiment 4 there is better sealing effectiveness, at the top of the first cavity 101 outer walls, can be provided for the outer 107 that the gland outer outer wall of the second cavity 201 210 tops do not arrange the part of elastic protrusion 212, as shown in figure 11.When 2 metal snap-fasteners 104 that are fixed on the first cavity 101 bottom outside are respectively when being fixed on 2 metal snap-fasteners 207 on dividing plate 204 and fastening, under outer 107, correct the tight pressing of part that elastic protrusion 212 is not set with the outer outer wall of the second cavity 101 211 tops.
In order to reach the effect of degree of depth waterproof, can between the protuberance 108 of the first cavity 101 outer walls and the outer outer wall 211 of the second cavity 201, sealed insulation pad 3 be set, as shown in figure 12.
