ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a connector case, such as a table tap, in which insertion ports are provided in two directions at right angles to the surface and side surfaces, and its purpose is to provide a connector case that is easy to manufacture. Provides the configuration of the case.

ない。 Conventionally, in order to improve the electrical insulation of this type of connector case and to prevent damage due to impact, the entire case, except for the insertion part of the plug blade, was wrapped in a protective body made of flexible synthetic resin. However, since the power connection cord is also molded and bonded in close contact with the protector, there is a drawback that if the power connection cord is cut, it cannot be reconnected. Therefore, if reconnection is to be considered, the connector case must allow connection terminals of internal electrical components to be exposed as necessary. If the connector case is made of a combination of two split cases due to such requirements, there is a problem in the molding of the main body and the retaining body that is attached to the outer surface of the main body to accommodate the electrical components that make up the split case. must be resolved.

ならないことである。 One is that the main body is made of a hard, heat-resistant thermosetting synthetic resin material such as phenol or urea resin, as it houses the blade holder and connection terminal that make up the connector, and the protective body However, it is made of soft and elastic synthetic resin materials such as nylon and rubber because it needs to be soft and resilient in order to cushion external impacts and prevent deformation.For this purpose, the primary molding process that plasticizes the main body, the protector and the main body are made. There is no misalignment with the secondary molding process that molds the outer surface,
It must be ensured that the main body and the protector are accurately integrated. Another problem is that when the protector is formed on the outer surface of the main body by molding in the secondary molding process, the protector material in a molten state wraps around the insertion part formed on the main body and hardens, causing thin burrs. The connector case must be designed to prevent this.

Furthermore, the end surface A of the protector 6 is positioned on a horizontal plane that is lowered by a distance G from the opening edge B of the main body 5, thereby shifting the joining line between the main body 5 and the protector 6, and , protector 6
The end face A of the mold is used as the parting line X3 of the mold for forming the divided cases 1a and 1b. By setting this parting line X3 , the divided cases 1a and 1b have the rising edges Y, Y', etc. of the main body 5 rising from the end surface A of the protector 6, which are necessary for removing one mold.

る。 Accordingly, in the present invention, after the primary processing of forming the main body 5 by plastic molding from a thermosetting synthetic resin material, a secondary molding process is performed in which the protector 6 of thermoplastic soft elastic nature is attached by forming. Since the parting line X 2 of the upper and lower molding dies in the primary and secondary molding coincides with the end surface A on the same horizontal plane, the outer surface of the protector 6 is formed when the main body 5 is molded. The thermoplastic material is transferred to another mold and injected into the cavity formed by the outer surface of the main body 5 and the other mold to be hardened. Therefore, one of the molds is shared, and the mold that forms the outer surface of the protector 6 is replaced in secondary processing.

is provided to cross the joint between the main body 5 and the protector 6, and the material of the protector 6 is inserted into the insertion portions 2 and 3 during plastic molding.
This prevents the hardening from flowing to the sides, and even if a small amount of hardening occurs, it will appear at the bottom of the groove 11, making it difficult to see from the outside and preventing it from degrading the appearance. This also applies to the insertion part 4 on the side, in which case the insertion part 4 protruding or recessed from the outer surface of the protector 6 connects the joining line between the main body 5 and the protector 6. positioning the joining line at the offset corner to prevent the thermoplastic material from flowing onto the surface of the insertion part 4;
Improve appearance.

ができる接続器ケースとなる。 As described above, according to the connector case of the present invention,
A connector case 1 has insertion parts 2 and 3 on the surface, and an insertion part 4 and a cord hole 5 on the side.
Two split cases 1 with horizontally split circumferential sides.
a, 1b, and each divided case 1a,
1b is provided with a main body 5 made of thermosetting synthetic resin that accommodates electrical components, and a protector 6 made of a soft elastic material molded on the outer surface of the main body 5, and an end surface A of the protector 6 is provided with a protector 6 made of a flexible elastic material. The end surface A is positioned on a horizontal plane that is one step below the opening rim.
is formed so that it can be used as the parting line X 3 of the mold for plastic forming the divided cases 1a and 1b, and the insertion portion 4 on the side surface is made to protrude outward from the surface of the protector 6 or to be recessed. Furthermore, the insertion parts 2 and 3 on the surface are formed with a groove 11 on the joining line between the main body 5 and the protector 6. A connector case with an accurate shape without misalignment with the protective body 6 formed by molding on the outer surface can be obtained,
In addition, the burrs of the thermoplastic material forming the protective body 6 do not go around the surfaces of the front insertion parts 2, 3 and the side insertion parts 4, and even if they do, they will not get caught in the groove 11 or the split case. In the combined state of 1a and 1b, it appears between the end faces A and A of the protector 6 and does not come out on the outer surface, resulting in a connector case that can ensure an accurate shape.
