Concentrate the syndeton of table box unit casing
Technical field
The utility model relates to the syndeton between the watt-hour meter table case, is specifically related to the syndeton of a kind of two or more ammeter boxes when installing concentratedly.
Background technology
In the city domestic power grid was transformed, Every household has an ammeter, and system was widelyd popularize, and the ammeter of next unit corridor of generalized case requires to install concentratedly together.In the prior art, if install several single household table casees concentratedly place an appointment, common way is that several single household table casees are leaned on side by side mutually, then its back side with bolt on the irony connection strap, thereby several single household table casees are linked into an integrated entity.The problem that this in the past mode is brought in actual installation is: 1, bolt hole need be opened in each single household table case back side, connects by bolt and goes up the irony connection strap, the attended operation trouble; 2, because the threading between case and the case by the side opening interconnection, causes threading to have one section to be exposed to outside the case, like this can not waterproof, stealing easily again.
Summary of the invention
The utility model purpose provides a kind of syndeton of concentrated table box unit casing, has both made things convenient for attended operation, solves the waterproof of threading between case and the case, anti-electricity-theft problem again.
For achieving the above object, the technical solution adopted in the utility model is: a kind of syndeton of concentrated table box unit casing is made of the cooperation of the mouth of connecting trough on contiguous block and the two adjacent unit box sidewalls; Described contiguous block is a rectangle, and its three limit outer rims are provided with groove, and this groove is convexed to form by outer rim both sides bead, and the contiguous block middle part offers through hole, and the through hole direction is vertical with the direction of groove; Described mouth of connecting trough also is a rectangle, and its limit towards the unit box rear is uncovered, and its other edge, three limits is corresponding with three limit grooves on the contiguous block as the embedding limit; Described several unit boxs are arranged side by side, and the mouth of connecting trough correspondence on the sidewall of adjacent cells casing is leaned on mutually, clamping in the three limit grooves of the corresponding embedding in three the embedding limits one described contiguous block of the mouth of connecting trough that it leans on mutually.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described through hole is one or more, and its hole shape is circle, triangle, rectangle, square, rhombus, trapezoidal or its combination.
2, in the such scheme, mouth of connecting trough is at least one on described unit box one sidewall, according to size, also can increase to two and three.Certainly, when the quantity of the mouth of connecting trough on unit box one sidewall was one, contiguous block also only needed one, and when mouth of connecting trough was two, contiguous block also needed two, and when mouth of connecting trough was three, contiguous block also needed three.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because the utility model is realized splicing between the table case by the groove structure on the contiguous block, can save like this at the table case back side and open fixedly irony connection strap of bolt hole, as long as thereby splicing the time will show case side by side the back card upward contiguous block be about to some table casees and be connected in one, attended operation is convenient, fast.
2, because the utility model will show between the case syndeton and cable channel combines, utilize threading via hole set on the contiguous block to come cabling, two cable channels of showing between the case are not exposed, so waterproof, anti-electricity-theft better performances.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: shown in accompanying drawing 1~8, a kind of syndeton of concentrated table box unit casing is made of 3 cooperations of the mouth of connecting trough on contiguous block 1 and two adjacent unit box 2 sidewalls.
Shown in accompanying drawing 1~4, described contiguous block 1 is a rectangle, and its three limit outer rims are provided with groove 4, and this groove 4 is convexed to form by outer rim both sides bead, and the contiguous block middle part offers threading via hole 5, and threading via hole 5 directions are vertical with the direction of groove 4.Threading via hole 5 is one or more, and its hole shape is circle, triangle, rectangle, square, rhombus, trapezoidal or its combination.
Shown in accompanying drawing 5, accompanying drawing 6, accompanying drawing 9, described mouth of connecting trough 3 also is a rectangle, and its limit towards unit box 2 rears is uncovered, and its other edge, three limits is corresponding with three limit grooves 4 on the contiguous block 1 as embedding limit 6.Specifically be on the outside surface of unit box 2 one sidewalls, to establish three mouth of connecting troughs 3 in upper, middle and lower altogether, sidewall is thicker, mouth of connecting trough 3 is located at its outside surface, and its inboard position of corresponding mouth of connecting trough 3 is also established through hole 7 and got through in casing, so that the electric wire between case and case feeds casing thus.
Shown in accompanying drawing 7~9, several (illustrating two) unit boxs 2 are arranged side by side, mouth of connecting trough 3 correspondences on the sidewall of adjacent cells casing 2 are leaned on mutually, clamping in the three limit grooves 4 of three embedding limits, the 6 corresponding embedding one described contiguous blocks 1 of its every pair mouth of connecting trough that leans on mutually 3.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the present utility model.
