。The electrical component cover 4 covers the relay 3 and the glass terminal 9.
In order to protect the product from impact, a structure is required that is easy to fix during the manufacturing process, and once fixed, cannot be removed without the use of tools to ensure safety. The operation of the conventional electrical component cover fixing device will be described below.
まず圧縮機１の本体に配設されたガラスターミナル９に
配線（図示せず）の終ったリレー３を挿入固定した後、
電装品カバー４を所定の位置に取り付け、クランプ６の

係止孔８に係止することにより電装品カバー４をブラケ
ット２に固定する構造となっている。First, after inserting and fixing the relay 3 with wiring (not shown) into the glass terminal 9 provided on the main body of the compressor 1,
Attach the electrical component cover 4 to a predetermined position, and while pressing down the electrical component cover 4 using the spring properties of the clamp 6, engage the engaging portion 7 of the clamp e into the locking hole 8 provided in the bracket 2. The structure is such that the electrical component cover 4 is fixed to the bracket 2 by stopping.

プ６のバネ性を利用してクランプ６を押シながら係り部
７をブラケット２に配設された係止孔８から外す事によ

。Next, when you want to remove the fixed electrical component cover 4, use the spring properties of the clamp 6 to push the clamp 6 and remove the engaging part 7 from the locking hole 8 provided in the bracket 2. The electrical component cover 4 can be removed from the bracket 2.
発明が解決しようとする問題点
しかしながら上記のような構成では、外しにくくしよう
とすれば固定時の作業性が大変悪くなる。Problems to be Solved by the Invention However, with the above configuration, if it is difficult to remove, the workability during fixing will be very poor.
しかもクランプ６のもっているバネ性のために電装品カ

ている場合などにはクランプ６のバネ部を押すだけで外
れる事となる。その結果電装品カバー４も外す事が出来
、リレー３、ガラスターミナル９等の充電部が露出する
事となり安全上重大な問題をもっている。Moreover, due to the springiness of the clamp 6, after the electrical component cover 4 is fixed, if you press the spring part of the Clamp 6, the engaging part 7 of the clamp 6 will come out of the locking hole 8 of the bracket 2, and you can manually remove it. By pinching, the clamp 6 can be removed without using a tool, and especially when the shape of the clamp 6 is expanded outward, it can be removed simply by pressing the spring portion of the clamp 6. As a result, the electrical component cover 4 can also be removed, exposing live parts such as the relay 3 and the glass terminal 9, which poses a serious safety problem.
問題点を解決するための手段

である。Means for Solving the Problems In order to solve the above problems, there is a method that fixes the electrical component cover with screws, etc., but since the workability becomes worse, the present invention does not have the same method as before. The electrical component cover fixing device of the present invention is intended to solve the problem in terms of workability. This structure makes it easy to insert the clamp and prevents it from coming off.

工具を用いずクランプを外す事は出来なくなる。Function: With the above-described structure, even if the electrical component cover is locked to the bracket by the clamp and the user attempts to remove it by pushing the spring part of the clamp, the inner wall of the tunnel with the lower step provided in the clamp guide part will hit. This prevents the clamp from popping out of the locking hole, and the eaves provided in the tunnel-shaped opening prevent it from being pinched by hand, making it impossible to remove the clamp without using a tool.

２３が外せる事となる。The operation of the compressor electrical component cover fixing device configured as described above will be explained. First, when fixing the electrical component cover 23 to the bracket 27 fixed to the compressor 21, after inserting and fixing the W snow relay 22 into the glass terminal 29 provided on the compressor 210 main body, the electrical component cover 23 is fixed. The electrical component cover 2 is attached to a predetermined position, and the electrical component cover 2
The bracket 27 of the electrical component cover 23 is inserted by inserting the clamp 24 into the tunnel-shaped portion 28 while pressing down the clamp 24, and locking the engaging portion 26 of the clamp 24 into the locking hole 26 provided in the bracket 27. The fixing is completed. At this time, when the clamp 24 is inserted into the tunnel-shaped part 28, it will pass through the passage 28a and hit the protrusion 32 with a one-step difference provided in the tunnel-shaped part 28, but it will be further energized. As time passes, the engaging portion 26 of the clamp 24 passes over the protrusion 32 and enters the passage 28b, allowing continued insertion. When the engaging portion 26 of the clamp 24 reaches the position of the locking hole 26 provided in the bracket 27, ,
The engaging portion 25 enters the locking hole 26 and fixation is completed. In this case, even if you press the spring part 31 of the clamp 24 and try to remove the clamp 24 from the bracket 27,
Since the eaves portion 30 is located above the part that can be pinched with hands, it is impossible to remove it by pinching with hands.
Further, even when the clamp 24 is slightly opened outward, the inner wall of the tunnel-shaped portion 2B of the passage 28a is
This prevents the locking part 25 from coming off from the locking hole 26, and prevents the clamp 24 from coming off easily. While holding down the spring portion 31 of the clamp 24, insert a flat tool (for example, a flat head screwdriver) between the bracket 27 and the clamp 24 from the space between the bracket 27 and the eaves portion 3o, and remove the flat plate. By twisting the shaped tool, the engaging portion 26 is forcibly removed from the locking hole 26, the clamp 24 can be removed from the outside, and the electrical component cover 23 can be removed.

問題をなくすことができる。As described above, according to this embodiment, by forming the guide portion of the clamp 24 of the electrical component cover 23 into the tunnel-shaped portion 28 having the step L and the eaves portion 30, the electrical component cover 23
The workability required for fixing 3 is almost the same as the current method, and it is impossible to remove without using a tool 9, which eliminates the problem of exposed live parts.

る。Effects of the Invention As described above, the present invention provides a clamp guide portion on the outer surface of the electrical component cover as a tunnel-shaped portion with a step and a canopy, and fixes the electrical component cover to the bracket with a substantially U-shaped clamp. Therefore, it is possible to prevent the electrical component cover from being removed from the bracket without using the intended tool, without impairing workability during fixing.
