This electronic device constitutes a housing of the electronic device by closing the opening 102 of the lower case 101 fixed to the wall by the upper case 103. The electronic device is not shown in the lower case 101 and the upper case 103 is accommodated in an electronic device (not shown). A stored electronic device (not shown) is connected by a cable. Accordingly, when the upper case 103 is removed from the lower case 101 in order to adjust the internal electronic device, the upper case 103 cannot be completely removed from the lower case 101. Therefore, the hook formed on the lower case 101 as shown in FIG. The upper case 103 is hangably connected to the lower case 101 by the string 107 by hooking the string 107 on the 104 and the mounting leg portion 106 of the inner cover 105.

  In addition, since the patent document corresponding to a prior art is not found, the description is abbreviate | omitted.

  However, since the hook 104 provided in the lower case 101 is relatively large in the above-described conventional configuration, it is necessary to secure an arrangement space thereof. Further, in the upper case 103, it is necessary to attach the inner cover 105 after the string 107 is hooked on the mounting leg portion 106 of the inner cover 105 of the lower case 101, which restricts the assembling procedure. Furthermore, in the lower case 101, since the string 107 is only hooked on the hook 104, the string 107 may be detached when the upper case 103 is opened (indicated by a two-dot chain line in FIG. 12).

  The present invention has been made in view of the above circumstances, and an object thereof is to manufacture a structure for connecting one case to the other case so that the case can be suspended, and can be manufactured without being restricted by an assembling procedure. An object of the present invention is to provide a housing structure for an electronic device that is not disconnected when the case is opened.

  According to invention of Claim 1, in order to connect one case to the other case so that suspension is possible, it latches by hooking the hole of a connection member on a projection part. In this state, the connecting member locked to the protruding portion is retained by the retaining portion, so that the connecting member can be prevented from coming off from the projecting portion when the case is opened. Further, since the connecting member is a thin strip member, the projection for locking the connecting member can be manufactured in a small size, and the arrangement space can be small. Furthermore, since the protrusion and the retaining portion are provided in the case independently of other assembly configurations, there are no restrictions on the assembly procedure.

According to the second aspect of the present invention, since the protruding portion and the retaining portion are provided inside the side surface of the case, it can be carried out without reducing the arrangement space of the electronic device stored in the case.
According to the invention of claim 3, in order to lock the hole portion of the connecting member to the protruding portion, the end portion of the connecting member is inserted between the protruding portion and the retaining portion. Then, since the retaining portion is elastically deformed in a direction away from the projecting portion and a gap is formed between the projecting portion and the retaining portion, when the end portion of the connecting member is further inserted into the back, the hole portion of the connecting member Can be locked to the protrusion. In this state, since the retaining portion is restored so as to elastically contact the protruding portion, the connecting member can be prevented from coming off from the protruding portion.

According to invention of Claim 4, since a projection part and a securing part can be resin-molded integrally with a case, a projection part and a securing part can be manufactured at low cost.
According to the invention of claim 5, the connecting member can be produced accurately and at low cost.
