Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a telephone housing structure in which recesses are provided on both sides of the telephone housing to function as gripping parts.

[Conventional technology]

As shown in FIG. 3, this type of conventional telephone housing structure consists of a combination of a case 6 having a handset and a cover 7 forming the back surface, and shallow recesses 8 are formed in the longitudinal direction on both sides of the cover 7. It is placed on the surface and functions as a grip for the housing.

[Problem that the invention attempts to solve]

In the above-described conventional telephone housing structure, the mold structure for injection molding the cover 7 is as shown in FIG. Therefore, it is necessary to construct a slide mold 11 that is movable perpendicularly to the mold opening direction, which leads to a complicated mold structure and increases the mold cost.

[Means for solving problems]

The telephone casing structure of the present invention has a structure in which shallow recesses are provided on both sides of the case and cover along the longitudinal direction, straddling the dividing surface of the phone casing, which is divided into two parts: the transmitting/receiving side and the back side. It's summery.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an external perspective view showing an embodiment of the present invention, and FIG. 2 is a sectional view showing a mold for forming the cover of the casing shown in FIG. The longitudinal recesses 3 provided on both sides of the phone housing allow the case 1 and the cover 2 to
They are provided on both sides across the dividing plane, and are structured to form one gripping recess 3 when combined. As shown in Fig. 2, the mold structure for the injection molding of the cover 2 is such that if the dividing surface 5 of the mold is set at the starting point of the recess 3, molding can be performed by simply dividing the mold in one direction. Is possible. This also applies to the mold structure of case 1.

[Effect of idea]

As explained above, the present invention enables the recessed part that functions as the grip part of the phone case to be molded to span both sides of the case and cover, thereby reducing the cost when molding the case using injection molding. This simplifies the mold structure, prevents deterioration in quality due to burrs on the mating surfaces of the molds, and reduces mold costs.

Claims (1)

[Scope of utility model registration request] In a telephone housing structure consisting of a combination of a case forming the handset side and a cover on the back side, a portion of the housing is formed on both sides of the case and the cover, and extends in the longitudinal direction of the housing in a manner that straddles the dividing surface thereof. A telephone housing structure, characterized in that both the case and the cover are formed with a shallow recess along which the grip becomes a gripping part.
