Description

[Detailed explanation of the idea] (b) Purpose of the idea The present invention relates to a glow socket.

Conventionally, due to poor contact or incomplete waterproofing, there are problems with waterproofing, and wire breakage occurs due to movement or vibration. However, the present invention was devised for the purpose of strengthening the connection of electric wires and making them completely waterproof.

(b) Structure of the idea Embodiments of the present invention will be described in detail below with reference to the drawings.

In the figure, reference numeral 1 denotes a socket body made of an insulating molded product, and a screw tube 2 is made to protrude upward from the center of the upper surface of the socket body 1, and a glow insertion opening 5 is inserted through the center of the body 1 and the inner peripheral surface of the lower part thereof. Near the lower end of the glow insertion port 5, this is cut horizontally into a thin ring to provide a ring-shaped horizontal surface 4, and further below that, the lower end of the glow insertion port 5 also has this as a horizontal surface 3. As described above, the glow insertion port 5 below the spiral tube 2 has two horizontal surfaces formed at the lower end surface and near the lower end surface.

An insulating seat plate 6 is provided below the main body 1 having such a configuration.
A central contact piece 7 and a side contact piece 8 are attached to the upper surface of the insulating seat plate 6, and terminals 9 and 10 are provided on the lower surface.
2 and an electric wire 13 are connected, and a long downward protrusion 14 is molded integrally with the insulating seat plate 6.

In order to fit the insulating seat plate 6 configured in this manner below the main body 1, the lower surface of the main body 1 must have a
Since spaces 15 are provided at both corners, rubber backings 20 are inserted into these spaces in advance.

A groove 23 for fitting the electric wire 13 is provided in the center of the backing 20.

The above-mentioned insulating seat plate is fitted to the bottom surface of the main body with the backing inserted into the spaces at both corners.First, the outer shape of the insulating seat plate is the same as the inner diameter of the glow insertion port. Since they are perfectly matched, the insulating seat plate is inserted into the glow insertion port in close contact with the glow insertion port, and in this case, the insulating seat plate is pushed in until it comes into close contact with the horizontal surface 4 and is completely fitted.

At this time, the electric wire attached to the fitted insulating seat plate passes through the recesses 17 provided on both sides under the main body, and by aligning the electric wire with the recess, the side contact piece is necessarily positioned so as to be accommodated in line with the vertical groove 25.

A separate presser plate 18 made of elastic rubber or the like is placed below the fitted insulating seat plate, and this presser plate is covered with a rubber backing having a groove 24 in the center into which the electric wire is to be fitted. 19 is glued to both corners, and the position of this backing 19 is provided in the same position as the backing 20, so by applying this presser plate, the electric wire is completely adhered to the upper and lower backings. It is fixed.

Finally, place a separate cover plate 21 of the same shape as the presser plate below the presser plate, and insert and fix the screws 22 into the screw holes provided in the same position for both the presser plate and the cover plate. Since the lower end surface of the main body has a groove formed in advance to match the outer shape and depth of the presser plate and the cover plate, the cover plate is housed completely flush with the lower end surface 16 of the main body. be.

(c) Effects of the invention The present invention, which has the above-mentioned configuration, is further completed by screwing the glow lamp through the guide strip 26 of the glow lamp, and the cap 27 and the waterproof band 28 attached to the top surface of the main body to match the cap. However, in the present invention, due to the above-mentioned configuration, the insulating seat plate is in close contact with the horizontal surface above it, the insulating seat plate is in close contact with the lower protruding part, and the presser plate is in close contact with this part. Since the board is in close contact with the horizontal surface 3 and is fixed with a cover plate at a predetermined position, it has a great waterproofing effect.Furthermore, since the electric wire is necessarily firmly fixed, contact pieces and terminal parts Since there is no deformation such as, etc., it is a practical device that has a unique effect that it does not inevitably become disconnected due to movement or vibration.

Claims (1)

[Scope of utility model registration request] The main body has an overall shape in which both sides of the upper surface of a rectangular parallelepiped are cut into approximately square shapes.A cylindrical through hole is passed through the center of the main body to serve as a glow insertion hole, and the lower end of the insertion hole is ring-shaped. A part of the peripheral wall that surrounds the horizontal surface and has the same inner periphery is made to protrude slightly below the ring-shaped horizontal surface, and its lower end is also a horizontal surface, and the horizontal surface is slightly higher than the lower end surface of the main body. It is made high, and its outside is cut into a rectangular parallelepiped shape to form a space of the same shape as the inner wall around the main body.On the other hand, there is also a separate peripheral wall that surrounds the ring-shaped horizontal surface and has the same inner circumference as this. The outer side of the main body is cut out in the same way, and a space of the same shape is formed at both corners of one side of the inner wall of the main body, and a disc-shaped insulating seat plate of the same diameter is formed on the horizontal surface of the ring. A rectangular central contact piece is attached horizontally to one end of the upper surface of the insulating seat plate, and a side contact piece of the same shape is attached vertically to the other end. A rectangular plate-shaped protrusion is integrally molded, and a nearly convex-shaped presser plate with a backing of the same shape as the space attached to both ends of one side is placed in contact with the lower end of the protrusion to create a backing. is fitted into the space, a cover plate of the same shape as the presser plate is placed below it, and a cutout of the same shape that allows storage of the presser plate and the cover plate is placed opposite the space on the inner surface of the main body.
