Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, the utility model includes spelling the first side plate 1 and the second side plate 2 interconnected during cabinet,
First side plate 1 and the second side plate 2 are separately positioned on the opposite sides of ring main unit, are both the left and right sides, the first side plate 1 and
It is provided with two side plates 2 by least two threading hole groups 4 constituted for the threading hole 3 through bus, generally general ring
Net cabinet can set three threading holes 3 with correspondence bus arrangement, so threading hole group 4 have three threading hole groups 4 into.Its feature exists
In：Male-type positioning head 5 and male-type positioning hole 6, male-type positioning head 5 are symmetrically arranged with the relative direction of threading hole group 4
Central point and male-type positioning hole 6 central point line by the central point of threading hole group 4, male-type positioning head 5 and
The setting of male-type positioning hole 6 is that, in order to be directed at threading hole 3, and threading hole group 4 has the composition of threading hole 3, so male-type
The line of centres of positioning head 5 and male-type positioning hole 6 allows for the position of threading hole group 4 through the central point of threading hole group 4
Put and be now uniquely determined, while the use of location structure can be greatly decreased in this structure, using only one group.First side plate 1
And second only set convex on a male-type positioning head 5 and a male-type positioning hole 6, the first side plate 1 on side plate 2
Play the set location and the male-type positioning head 5 and male-type on the second side plate 2 of type positioning head 5 and male-type positioning hole 6
The set location of positioning hole 6 mirror position each other, can excessively lead if male-type positioning head 5 and male-type positioning hole 6 are set
Resistance becomes big when causing the ring main unit to spell cabinet, while add the accurate requirement of processing, the male-type positioning head 5 of the present embodiment with
And the setting purpose of male-type positioning hole 6 be in order to which positioning action does not really want to play the effect such as fixed, so.In threading hole group 4
Centre-to-centre spacing between two threading holes 3 of arbitrary neighborhood is equal, so removes the requirement in electrical design, determines while also meeting
The requirement of position accuracy.The edge of the end of male-type positioning head 5 is provided with termination chamfering, the port of male-type positioning hole 6
Edge is provided with the angle identical port chamfering with termination chamfering.Male-type positioning head 5 and male-type positioning hole 6 are complete
Metal structure, eliminates the trickle displacement that relative deformation therebetween is produced using all-metal construction, can thus eliminate positioning
Produced because of the reason for deformation it is inaccurate the problem of, be so that prior art can not be accomplished using parts such as rivet, screws,
The parts such as rivet, screw will necessarily produce certain relative displacement during locking, and the displacement can not almost be eliminated, and this reality
The relative activity direction for applying example is only the activity without producing the axial direction twisted to screw etc. in stitching direction.
As shown in figure 5, at least one reinforcement 7 is provided with first side plate 1 and the second side plate 2 of the present embodiment, the
The set location of reinforcement 7 on side plate 1 and the mutual sequence of set location of the reinforcement 7 on the second side plate 2.Male-type is determined
Position hole 6 and the first side plate 1 or the second side plate 2 retreat structure 8 and are attached by pressing, and male-type positioning hole 6 is determined along male-type
The direction of insertion of potential head 5 is set with respect to the first side plate 1 or the linear activity of the second side plate 2, and the structure setting, which is directed to, to be needed to eliminate
The demand in gap is set between two ring main units, can be continued to drill after the completion of positioning between orientation reduces using the structure
It can ensure that the positioning of the second, opposite, side plate 2 of the first side plate 1 is not damaged in gap, whole process, so the structure can be matched.Point
Structure 8 is moved back in compression to be included being used to positioning hole will be made along male-type to determine after the fully-inserted male-type positioning hole 6 of male-type positioning head 5
The direction of insertion continuation of potential head 5 is linearly moving to be retreated device 8-1 and retreats device for the triggering of fitting projection type positioning head 5
The point driving switch 8-2 of 8-1 activities.Point driving switch 8-2 is arranged at the hole heart bottom of male-type positioning hole 6, and retreating device 8-1 includes
With the first side plate 1 or the second side plate 2 affixed rack 8-1-1 and screens groove 8-1-2, the rear end of male-type positioning hole 6 is set
There is the arc salient point 6-1 coordinated with rack 8-1-1, the rear end of point driving switch 8-2 rear end parts and male-type positioning hole 6 is affixed,
Gap is provided between the rear end of another part and male-type positioning hole 6, point driving switch 8-2 rear end is connected with and screens groove 8-
The buckle 6-2 of 1-2 clampings, when point driving switch 8-2 is pressed down, point driving switch 8-2 is to there is affixed side curving, now buckle 6-2
Released with screens groove 8-1-2, such male-type positioning hole 6 is with regard to that can be moved rearwards by, and it is fixed to facilitate that rack 8-1-1 provides anchor point
Position.The planar portions 6-2-1 that buckle 6-2 is oppositely arranged including two for being offseted with screens groove 8-1-2 medial surfaces, two planes
A rake 6-2-2, planar portions 6- for being used to facilitate buckle 6-2 to slip from screens groove 8-1-2 is provided between portion 6-2-1
2-1 can ensure that buckle 6-2 is not released usually.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected in right of the present utility model by Patent Law.
