Description

[Detailed explanation of the idea] Industrial applications The present invention relates to an electrical connector.

Conventional configuration and its problems Generally, in a lighting system used in a refrigerated storage case, an electric connector is attached to the end of the cord that supplies power to the lighting device installed under the shelf of the storage case, and the electrical connector is fixed to the back plate of the storage case. A configuration in which the food is connected to a corresponding electrical connector is adopted, but the former electrical connector is configured so that it does not protrude from the back plate as much as possible to secure storage space for food items to be displayed on the shelf. There is a need. Therefore, the cord is introduced from the back side of the electrical connector and connected to the internal electrical connector, and the back of the electrical connector is also provided with a grip that can be held with your fingers when pulling out the electrical connector. It is configured to be formed as small as possible. In the past, some gripping portions were formed with a fairly large diameter, but while they were easy to pull out, they had the disadvantage of increasing the cost of molding materials, so it was better to form them as narrow as possible.

However, since the width and length of the introduction part of the cord are quite necessary, it affects the width of the gripping part, and it is difficult to design it within a certain limit, and there is a problem that it cannot be improved much in terms of saving materials. Since the cord is introduced in a straight line, if it is assumed that the cord is pulled and pulled out, the tension of the cord will be applied to the connection part with the electrical connector, creating a risk of disconnection.

OBJECTS OF THE PRESENT DEVICE The present invention has been made in consideration of the above problems, and aims to provide an electrical connector which saves materials, ensures ease of removal, and prevents the cord from breaking.

Structure of the Device In order to achieve the above object, the present invention is an electrical connector whose outer shell is molded with synthetic resin, and a narrow gripping portion is formed on the back side, and a cord is introduced from the side of the gripping portion. This constitutes an electrical connector that is bent forward to avoid this grip and connected to an internal electrical connector.

DESCRIPTION OF EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

The drawing shows an electrical connector A whose outer shell is molded from synthetic resin, with a cylindrical front part, a narrow grip part 1 formed on the back side, and a cord 2 from the side of the grip part 1. is introduced, bent forward so as to avoid the grip part 1 (2' is the bent part), and connected to the electrical connector 3 inside. That is, although the width of the cord introduction part 4 is required to be quite large, the cord 2 has a bending part 2'.
Since the gripping portion 1 is molded from resin as the outer shell, the gripping portion 1 is kept relatively narrow and quite long.

FIG. 3 shows another electrical connector 6 attached to the back plate 5.
In this state, the electrical connector A is pushed in and connected, and in order to have a waterproof effect, a waterproof ring 7 made of rubber or the like is attached to the outer periphery of the electrical connector A, and is pressed against the inner surface of the electrical connector 6. There is.

When pulling out the electrical connector A, it is sufficient to grasp the grip part 1 with your fingers, but the waterproof ring 7
It is also related to the fact that there is a
It is easy to pull the cord 2 first, then grasp the grip part 1 and pull it out. Even in such a case, since the cord 2 has the bent portion 2', almost no force is applied to the connecting portion 3' with the electrical connector 3, and breakage of the cord 2 can be prevented. Since the grip portion 1 is quite long, a space for gripping with fingers is secured, making it easy to pull out, and a considerable effect can be achieved in terms of material saving.

Effects of the invention From the details described above, it is clear that the present invention eliminates the risk of cord breakage even if the cord is pulled out by holding it by mistake, and the gripping part used for normal pulling is also small. Since it is formed in a wide and long shape, it has the advantage of being easy to pull out because it can secure enough space for grasping the fingers, and furthermore, it is accompanied by a considerable material saving effect.
