Description

[Detailed Description of the Invention] The present invention relates to a downlight socket mounting structure.

In the conventional downlight socket mounting structure, as shown in FIG. 2 at the top of the hole, fix the fixed leg 3 and the socket base plate 1 with screws 4, and attach the socket 2 to the socket base plate 1.
It was fixed at

Therefore, the installation work is troublesome, and when removing the socket 2 from the socket base plate 1, it is troublesome to remove the screws 4 that are tightly screwed together.

The present invention was developed in view of the above-mentioned drawbacks, and its purpose is to provide a downlight socket mounting structure that allows the socket to be easily attached to and removed from the socket base plate. be.

The present invention will be explained below with reference to examples.

The socket base plate 1 has a socket fitting hole 5 having a shape substantially equal to the cross-sectional shape of the socket 2 main body, and notch holes 6 are continuously formed on both side opening edges of the socket fitting hole 5. It is something that

The socket 2 is formed from a bottomed cylindrical body, and engaging claws 7 are provided on the outer walls of the lower ends of both sides of the socket 2, respectively, protruding outward. Presser claws 8 are provided on the outer wall of the socket 2 to protrude outward, respectively.
Furthermore, a notch groove 9 is provided on both outer walls of the socket 2, which is opened at the lower end and dug upward, with the engaging claw 7 rotated 90 degrees from the position, and a stopper is integrated into the notch groove 9 so as to be able to move up and down. 1
0, and a spring body 11 interposed between the upper end of the stopper unit 10 and the upper end of the notch groove 9 constantly closes the stopper unit 10.
is biased downward by a spring.

Here, the width and length of the engaging claw 7 are set to such a size that it can pass through the notch hole 6 upwardly and downwardly, and there is a gap between the upper surface of the engaging claw 7 and the lower surface of the presser claw 8. The distance is set to be larger than the thickness of the socket base plate 1.

The stopper unit 10 has an outer side projecting outward from the side opening of the notched groove 9, and has tapers 12 on both sides of the lower end.

When attaching the socket 2 to the socket base plate 1, the socket 2 is first pushed down so that both engaging claws 7 of the socket 2 are inserted into the notch holes 6 from above as shown by arrows F.

At this time, the lower end of the stopper unit 10 is pushed upward by the upper surface of the socket base plate 1 at the opening periphery of the socket fitting hole 5, and the stopper unit 10 compresses the spring body 11 in the notch groove 9 while making the notch groove. 9 and the lower part of the socket 2 is fitted into the socket fitting hole 5.

When socket 2 is rotated 90 degrees in this state, spring body 1
1 spring biasing force causes the lower end of the stopper unit 10 to close to the notch hole 6.
fall inside.

Here, as shown in FIG. 4, the width of the stopper unit 10 is
Since the width a is set larger than the width a, the taper 12 is engaged so as to bite into the notch hole 6.

On the other hand, the socket base plate 1 at the opening periphery of the socket fitting hole 5
is in a state where it is held between the presser claw 8 and the engagement claw 7 as shown in FIG.

In this way, the swinging of the socket 2 in the rotational direction can be suppressed by the engagement between the taper 12 of the stopper unit 10 and the notch groove 9, and the upward and downward rattling can be prevented by the presser pawl 8 and the engaging pawl 7. This can be suppressed by holding the socket base plate 1 between the socket base plates 1 and 1.

Next, when removing the socket 2 from the socket base plate 1, the stopper unit 10 is pushed upward, and the lower end of the stopper unit 10 is placed on the socket base plate 1 at the opening periphery of the socket fitting hole 5.
When socket 2 is rotated 90 degrees while riding on top,
The engaging pawl 7 matches the notch hole 6, and when the socket 2 is lifted upward at that position, the engaging pawl 7 comes out of the notch hole 6, and the socket 2 can be removed from the socket base plate 1.

The present invention provides a notch hole continuous with the socket fitting hole on both sides of the socket fitting hole drilled in the socket base plate,
Engagement claws that can be inserted vertically into the notch holes are provided protrudingly on the outer wall of the lower end of the socket, and together with the engagement claws on the outer wall of the socket above each engagement claw, the socket base plate is located on the periphery of the opening of the socket insertion hole. Since the presser claws that clamp the socket are protruded, the socket base plate around the opening of the socket insertion hole can be clamped by inserting the engaging claws into the notched holes from above and rotating the socket. Moreover, the lower end of the stopper, which is attached to the outer wall of the socket at a fixed rotational angle away from each engaging claw so as to be movable up and down and is constantly biased downward by a spring, is engaged in the notch hole, so that the socket base plate It is possible to prevent vibration in the direction of rotation, and the above-mentioned structure also suppresses rattling in the upward and downward directions, and the socket can be securely fixed to the socket base plate without having to be fixed with screws. It has the advantage that it can be easily installed and removed by simply rotating the socket.

In particular, in this invention, since the spring body always biases the stopper unit downward, when the stopper unit slides on the socket base plate until the stopper unit engages in the notch hole, the stopper unit is biased downward. In order to retract against the bias, it is possible to make the space between the retaining piece and the holding piece close to the thickness of the socket base plate, and therefore the upper part.

It is possible to almost eliminate rattling during downward movement, and the position of the stopper is separate from the engagement piece and presser piece.
When screwing the lamp into the socket, even if an upward or downward force is applied to the socket, the above-mentioned retaining piece and presser piece can suppress the upward or downward movement of the socket. This has the advantage that it is less likely to fall off, and as a result, rotation of the socket can be reliably stopped when the lamp is attached.

Moreover, as described above, if the stopper unit is biased downward by a spring and tapers are formed on both sides of the bottom end of the stopper unit, the stopper unit and the notch hole can be securely engaged without any looseness.
