Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to electrical connector devices for making electrical connections through panels.

Conventional Structure and Problems Conventionally, in refrigerated showcases, in order to supply power to the lighting equipment for illuminating the shelves, the lighting equipment and the lighting equipment were connected to a power supply connector provided on the back panel on which the shelves were hung. Connect the connected power receiving connector. In such cases, an annular collar piece with the end bent outward is formed on the edge of the elastic synthetic resin receiver that forms the outer shell of the power supply connector.
This flange piece is elastically deformed and press-fitted into a mounting hole formed in the panel, and the flange piece is fixed and attached to the edge of the mounting hole. However, in this attachment means, since the collar piece is annular, it is not easy to elastically deform, and there is a drawback that it is difficult to press fit into the attachment hole.

Furthermore, when grasping the outer periphery of the power receiving connector with your fingers in order to pull out the power receiving connector that has been inserted into the inside of the receiving sleeve and electrically connected to the power feeding connector f', the collar piece gets in the way and makes it difficult to pull out the power receiving connector. Since this is difficult, it is necessary to take measures such as providing a pull-out handle or a ring on the rear surface of the power-receiving connector, resulting in a large-scale construction and high cost.

Purpose of the Invention The present invention fundamentally solves the above-mentioned drawbacks, and makes it easy to attach one of the connectors to a mounting surface such as a panel, as well as to easily attach the other connector connected to this connector. Its purpose is to facilitate removal.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is provided with a receiving tube made of elastic synthetic resin, and has a plurality of cut portions formed between the edges thereof, and a plurality of grooves with the ends bent outward. A first connector provided with a claw piece and a mounting hole are formed, the claw piece is elastically deformed and pressed into the mounting hole, and the claw piece is locked to the edge of the mounting hole. A mounting surface to which the first connector is attached, and a second connector which is electrically connected to the first connector by being inserted into the receiver and is attached so that its rear end slightly protrudes beyond the claw piece. This constitutes an electrical connector device characterized by comprising two connectors.

Description of examples Next, embodiments of the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a first connector, which is equipped with a receiving sleeve 2 made of elastic synthetic resin such as polypropylene or nylon. A plurality of claw pieces 3, whose ends are bent outward, are provided on the edge of the receiving tube 2 between the cut parts 4.

Furthermore, a guide groove 5 is provided inside the cut portion 4 . A contact piece 6 is provided inside the first connector 1, and this contact piece is electrically connected to a lead wire 7. Reference numeral 8 denotes an insertion hole into which a conductive pin of a second connector to be described later is inserted. Reference numeral 9 denotes a mounting surface such as a panel, on which a mounting hole 1° is formed.
The first connector 1 is mounted by pressing the claw pieces 3 into the mounting hole 1o and locking them to the edge of the mounting hole 1o. Reference numeral 11 denotes a second connector, and when inserted into the receiving sleeve 2, a conductive pin 12 provided inside passes through the insertion hole 8, contacts the contact piece 6, and is electrically connected to the first connector 1. Connected. In this connected state, the rear end portion of the second connector 11 is attached so as to protrude slightly from the claw pieces 3. A recess 13 for a finger rest is formed on the outer periphery of the rear end of the second connector 11, and a lead wire 14 connected to the conductive pin 12 is provided from one side of the rear end. ing. Further, a plurality of protrusions 16 formed on the outer periphery of the second connector 11 are inserted into the guide groove 6 to position the first connector 1 and the second connector 11. To attach the first connector 1 to the mounting surface 9, push the claw pieces 3 into the mounting hole 10, and the claw pieces 3 with the cutout 4 formed therebetween will elastically deform inward. Since it is easy to remove, it can be easily press-fitted, and the claw piece 3 is locked to the edge of the mounting hole 10 to complete the mounting.

When pulling out the second connector 11 from the first connector 1, the finger indicated by the dotted line as shown in FIG. The part is wider and can be easily pulled out. A waterproof ring 16 made of a soft material such as rubber is fitted around the outer periphery of the second connector 11, and when attached to the first connector 1, the waterproof ring 16 comes into pressure contact with the inner circumferential surface of the receiving tube 2, making it waterproof. It has an effect.

Effects of the Invention The present invention described above has the following excellent effects.

(1) On the edge of the receiver that constitutes the first connector, a plurality of claw pieces are provided with the ends bent outward, with cutouts formed between them, so that they fit into the mounting holes on the mounting surface. The claw piece is elastically deformed and press-fitted easily, and the installation is easily completed.

(2) Because of the cutout, when pulling out the second connector, the rear end of the second connector can be grasped by positioning the fingers within the cutout, making the pulling operation extremely easy.
