The figure is a front view with the relay rack panel removed.
In the figure, 1 is a relay rack panel, and 2 is a relay socket. The relay rack panel 1 is provided with a mounting hole 3 penetrating from the front side to the back side, and the socket 2 is inserted into the mounting hole 3.

The socket 2 has an insertion portion 2a that is inserted into the mounting hole 3 and has a small diameter.A collar portion 2b that is larger than the mounting hole 3 is connected to the insertion portion 2a, and this collar portion 2b is connected to the relay. It is located on the front side of the rack panel 1. Grooves 4 and 5 in the form of through holes are provided in the flange portion 2b at both ends of the socket 2, respectively.

Then, the first lock piece 6 and the second lock piece 7 are respectively inserted into the grooves 4 and 5, and between the first lock piece 6 and the inner wall surface of the groove 4, , second lock piece 7 and groove part 5
The locking pieces 8, 8 are press-fitted into the gaps created between the locking pieces 8, 8, and the inner wall surface of the
8, the first lock piece 6 and the second lock piece 7 are pressed and fixed to the socket 2.

The locking piece 6 is made of a thin plate material, and as shown in FIG. , 6a, an arbitrary number of notches 6b protruding in the direction opposite to the locking pieces 6a are provided at appropriate intervals. In the state shown in FIG. 1, the latching piece 6a protrudes to the back side of the relay rack panel 1 through the mounting hole 3 so as to be latched to the edge of the mounting hole 3 on the back side of the relay rack panel 1. I have let you. Further, the cutout piece 6b is inserted into the groove 4 so as to be hooked onto a step 4a provided in the groove 4 of the socket 2.

Furthermore, the second lock piece 7 is made of a thin plate material similar to the first lock piece 6, and as shown in FIG. 7a is bent and formed, and an arbitrary number of cutout pieces 7b are provided at appropriate intervals from the hooking piece 7a and protruding at an angle in the same direction as the hooking piece 7a. In the state shown in FIG.
Pass through the mounting hole 3 to the back side of the relay rack panel 1 so that the sloped surface of a is inclined downward toward the outside of the mounting hole 3, and the notched end is latched to the back side of the relay rack panel 1. It is protruded from the side. Further, the cutout piece 7b is inserted into the groove 5 so as to be hooked onto a step 5a provided in the groove 5.

Furthermore, the locking pieces 8, 8 are made of a plastic material such as nylon 6, and have a structure in which an inclined part 8a is provided on one end side, and protrusions 8b, 8b which stand upright at right angles are provided on both sides of this inclined part 8a. It is becoming. The locking pieces 8, 8 are press-fitted between the first locking piece 6 or the second locking piece 7 and the inner wall surfaces of the grooves 4, 5 in order to fill the gap between them. In this case, the inclined parts 8a, 8a
is press-fitted into the mounting hole 3 on the front side of the relay rack panel 1 in an upwardly inclined direction toward the outside.

Then, between the latching piece 6a of the first locking piece 6 and the inclined part 8a of the locking piece 8, and between the latching piece 7a of the second locking piece 7 and the inclined part 8a of the locking piece 8. The relay rack panel 1 is sandwiched between both sides. As a result, the first locking piece 6 and the second locking piece 7 are pressed and fixed to the inner wall surfaces of the grooves 4 and 5 of the socket 2, and the hooking piece 6a of the first locking piece 6 and the locking piece 8 The socket 2 is pushed into the mounting hole of the relay rack panel 1 by the elastic action generated between the second locking piece 7 and the inclined part 8a of the second locking piece 7 and between the locking piece 7a of the locking piece 7 and the inclined part 8a of the locking piece 8. It will be elastically fixed within 3.

Here, the first lock piece 6 and the second lock piece 7 have cutout pieces 6b and 7b that are connected to the groove portion 4 of the socket 2,
5, the first lock piece 6 and the second lock piece 7
There is no fear that the material will fall out of the grooves 4 and 5.

Further, since the lock holding piece 8 is arranged such that the inclined portion 8a is inclined upwardly toward the outside of the mounting hole 3 on the front side of the relay rack panel 1,
The relay rack panel 1 is sandwiched from both sides between the inclined portion 8a of the locking piece 8, the latching piece 6a of the first locking piece 6, and the latching piece 7a of the second locking piece 7. When an external force is applied to the socket 2, the inclined portion 8a becomes elastically deformed in such a direction that its elasticity increases in response to an increase in the external force, and decreases in its elasticity in response to a decrease in the external force. Moreover, after the first locking piece 6 and the second locking piece 7 are hooked and fixed in the grooves 4 and 5 of the socket 2, the elasticity of the sloped part 8a of the locking piece 8 is used to lock the relay rack panel 1. Since it is sandwiched between both sides, there are almost no gaps. Therefore, a socket mounting device that is extremely resistant to vibrations and the like and has high mounting stability can be obtained. Also,
When inserting a relay into the socket 2 from the front side of the relay rack panel 1, or when connecting various connectors from the back side of the relay rack panel 1, a considerable external force is applied to the socket 2. However, it can sufficiently withstand these external forces. Furthermore, since the protrusion 8b is provided on the side of the inclined portion 8a of the locking piece 8, there is no possibility that the locking piece 8 will sink into the grooves 4, 5.

Furthermore, since the structure is such that the first lock piece 6, second lock piece 7, and lock presser pieces 8, 8 are inserted into the grooves 4, 5 provided in the socket 2, the painted surface of the relay frame panel 1 may be damaged. Never.

Furthermore, when attaching the socket 2 to the relay rack panel 1, as shown in FIG. 2, insert the insertion part 2a of the socket 2 into the mounting hole 3, and insert the first
Insert the end edge of the relay rack panel 1 between the hooking piece 6a of the locking piece 6 and the inclined part 8a of the locking piece 8, and then using this sandwiching as a fulcrum,
Press in the direction of arrow a. Then, since the hooking piece 7a of the second locking piece 7 forms an inclined surface that slopes downward toward the outside of the mounting hole 3, the edge of the mounting hole 3 is hooked, as shown in FIG. 6b. The locking piece 7a is pressed while sliding on the inclined surface of the locking piece 7a, and the locking piece 7a projects to the back side of the relay rack panel 1. This results in
As shown in FIG. 1, between the hooking piece 7a of the second locking piece 7 and the inclined part 8a of the locking piece 8,
The structure is such that the relay rack panel 1 is inserted and fixed from both sides. As described above, according to the present invention, the first locking piece 6 side is attached to the relay rack panel 1, and then the second locking piece 7 side is pressed against the relay racking panel 1, so that the relay can be easily installed. . Furthermore, since this mounting work can be carried out by only one person from the front side of the relay rack panel 1, the workability of mounting and fixing the socket 2 is significantly improved.

As described above, according to the present invention, it is possible for one person to easily attach and fix the relay socket to the relay rack panel, and it is also able to withstand external forces such as the relay insertion force. Furthermore, it is possible to provide a relay socket mounting device that is resistant to vibrations and has high mounting stability.
