Description

[Detailed Description of the Invention] This invention relates to a container for electrical equipment, such as a photoelectric automatic blinker or an intercom, which is installed outdoors, and which stores electronic parts therein.

Conventionally, in this type of container, as shown in Fig. 1, the opening of the through-hole of the leader wire A is sealed with a rubber button. Water may get inside.

Further, the tension applied to the leader wire A may be applied to the connection point between the leader wire A and the board on which the electronic component E is mounted.

This idea was made focusing on the above circumstances,
The purpose is to completely waterproof the through hole of the leader wire, prevent the tension applied to the leader wire from being applied directly to the inside, and provide a container for electrical equipment that is easy to assemble.

An embodiment of this invention will be described below with reference to FIG.

Reference numeral 1 denotes a board, on which electronic components 2 are mounted and lead wires 3 are connected.

Reference numeral 4 denotes a container, which is composed of a container body 5 and a lid 6. The covering of the leader wire 3 is peeled off at the part that contacts the container body 5 and the lid 6 to expose the core wire 3a. A through hole 7 having approximately the same diameter as the core wire 3a is formed on the contact surface of the body 6, and the core wire 3a is inserted into the through hole 7.
to fit.

Further, tension stop portions 8 are provided extending outward from the outer wall surfaces of the container body 5 and the lid body 6 near the through hole 7, and the ends of these tension stop portions 8 have lead-out lines in opposite directions. It has a protruding claw that bites into the cover of No. 3 and locks it.

When the container body 5 and the lid body 6 are melt-bonded and assembled by ultrasonic bonding, the claws of the tension stopper part 8 are embedded in the coating and lock the lead wire 3, and the through-hole where the core wire 3a is fitted. The resin around the hole 7 melts and fills the gap between the core wires 3a.

At this time, the closer the core wire 3a and the through hole 7 are fitted, the more easily melting occurs.

The present invention is constructed as described above, and a through hole having approximately the same diameter as the core wire of the leader wire exposed by peeling off the steps is bored in the welded abutment part of the container body and the lid body. Therefore, when the lid body and the container body are bonded together by ultrasonic bonding, the molten resin flows into the through hole and fills the gap between the core wires, eliminating the capillary phenomenon caused by the core wires, completely sealing the through hole and making it waterproof. A tension stopper is provided with a claw at the tip that bites into the covering of the leader wire from at least the top and bottom and extends outward from the outer surface of the container body and the lid body near the opening of the through hole, respectively. There is an advantage in that the tension applied to the lead wire from the inside can be prevented from being applied directly to the connection portion with the internal board or the through hole.
