Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a synthetic resin bus bar support device used in a distribution board or the like.

(Prior Art) A synthetic resin bus bar support device used in a conventional distribution board, etc. supports a bus bar 53 that conducts electricity from a main switch 51 to a branch switch 52, as shown in FIGS. 4 and 5. The bus bar 53 was attached and fixed to the base 54 with screws 55, but
Not only does it take a lot of effort to attach and fix the support base 54 using the synthetic resin support base 54, but the support base 54, which is made of synthetic resin, is prone to screw defects and lacks reliability.

(Problems that the invention attempts to solve) This invention solves these conventional problems,
This device was completed with the aim of providing a synthetic resin bus bar support device that allows the bus bar to be easily attached and that does not cause screw defects.

(Means for Solving the Problems) The present invention arranges a plurality of upright plate sections in parallel on a band at required intervals, forms a support section between adjacent upright plate sections, and Locking claws for locking the top surface of the bus bar are provided on the wall surfaces of the upright plates on both sides of each support base, and locking claws for locking the top surface of the bus bar are provided on the upper end of each of the outermost upright plates for attaching a protective cover. It is characterized by providing a locking part.

(Example) Next, an example of the present invention will be described in detail based on FIGS. 1, 2, and 3.

Reference numeral 1 denotes a substrate, and on the upper surface of the substrate 1, four upright plate portions 2 are arranged side by side, two on the outside and two on the inside, at intervals comparable to the width of the bus bar 53.
Reference numerals 3, 3, and 3 are support base parts formed between adjacent upright plate parts 2, 2, and two support bases formed between the outer upright plate parts 2, 2 and the inner upright plate parts 2, 2. The parts 3, 3 are placed in a high position, and the inner standing plate parts 2, 2
A central support portion 3 formed between the two is formed at a low position. Reference numerals 4 and 4 designate locking claws that lock both sides of the upper surface of the bus bar 53 supported on the upper surface of each support base part 3; At least one of the locking claws 4
is in the shape of a notch that is gently inclined from the wall surface 2a of the upright plate portion 2 in order to facilitate the locking operation of the bus bar 53 to the locking pawl 4. Also, the bus bar 53
In order to allow the locking claws 4, 4 to be easily opened and expanded when passing through, at least one side of the support base portion 3 is formed as a bottom stepped portion 3a. Reference numerals 5 and 5 denote locking portions for attaching the protective cover provided at the upper ends of the outermost upright plate portions 2, 2, and a hook portion 6 for preventing removal is formed outwardly on the outside of each locking portion 5. ing. 7, 7 is an engagement claw provided at the lower end of one side of the board 1 for engagement with the engagement hole 61 of the base 60 of the distribution board, and 8 is provided at the edge of the extension plate portion 1a of the board 1. The U-shaped notches 9, 9 through which the male screws 62 are inserted are reinforcing plates formed below between the outer upright plate parts 2, 2 and the inner upright plate parts 2, 2. Numerals 10, 10, and 10 are protrusions protruding from the upper surface of each support base 3, which fit into holes such as screw insertion holes of the busbar bar 53, and are inserted into the busbar bar 53.
This prevents the movement of 3.

(Function) With this configuration, the locking claws 7, 7 of the board 1 are connected to the engaging holes 61, 61 of the base 60 of the distribution board.
It is used by attaching it to a distribution board by screwing a male screw 62 into a U-shaped notch 8 provided in the extension plate portion 1a of the board 1, and connecting the branch switch 52 from a main switch (not shown) to a distribution board. By pressing the bus bar 53 that branches into
The busbar bar 53 is fixedly attached to the support base part 3 by holding the upper ends of both sides of the busbar bar 53 by locking claws 4, 4 which are protrudingly provided opposite to a, 2a. Since the busbar support device of the present invention is made of synthetic resin, the spacing between the locking claws 4, 4 protruding from the wall surfaces 2a, 2a of the upright plate parts 2, 2 is such that the busbar bar 53 can be attached to the support base part 3. When supporting, it is forcibly opened and the bus bar 53
When it passes between the locking claws 4, 4 and is completely supported by the support base part 3, the locking claws 4, 4 return to the old state and automatically lock both sides of the upper surface of the bus bar 53. Therefore, the bus bar 53 can be attached to the support base 3 very easily. In addition, since locking portions 5, 5 for attaching the protective cover are provided at the upper ends of each of the outermost upright plate portions 2, 2, there is no need to separately provide a member for attaching the protective cover, and the locking portions 5,5
By attaching the protective cover 63 to the outermost upright plate portions 2, 2, the outermost upright plate portions 2, 2 are prevented from expanding outward, so there is a risk that the space between the aforementioned locking claws 4, 4 will expand and the busbar bar 53 will fall off. There is no such thing.

(Effects of the invention) As is clear from the above explanation, the invention has the following effects:
This makes it possible to easily attach the bus bar to the support base, and also prevent screw failures that occur in the prior art. In addition, the present invention prevents the locking claws that lock the bus bar from opening by attaching a protective cover to the locking portion provided on the outermost upright plate, eliminating the risk of the bus bar falling off. This, combined with the advantage of reducing the number of parts,
The practical value of this device is extremely great as it eliminates the problems of the conventional busbar support device of this type.
