Description

[Detailed Description of the Invention] The present invention relates to a structure for preventing erroneous operation of a telephone switch.

2. Description of the Related Art Electric circuits of telephones, for example those used in vehicles, are rapidly becoming smaller. For this reason, there is an increasing number of so-called handset-type telephones with a handset, in which the switch and circuitry housed in conventional general-purpose telephones are mounted in the handset, and it functions as a telephone by itself. For this reason, the part corresponding to the main body of a general-purpose telephone no longer has any electrical functions, and has come to be used only for operating the touch switch and holding the handset.

Since the line connection operation of the telephone switch is a function for starting use of the telephone, it is desirable that the attachment and detachment of the handset from the holder and the operation of the telephone telephone are linked. Conventionally, as shown in Figures 1 to 3,
The protrusion 4 provided on the holder 3 is fitted into the recess 2 on the handset 1 side, and at the same time the pin 6 built in the recess 2 is inserted.
It was common practice to move the switch 7 and operate the switch 7. With this structure, even the laborious and rough work of attaching and detaching the handset 1,
The recess 2 must be made large so that the handset 1 can be reliably attached to and removed from the holder 3. For this reason,
The fingers of the hand holding the handset 1 unconsciously enter the recess 2 of the handset 1, causing an erroneous operation in which the switch 7 is operated, resulting in shortcomings such as sudden disconnection of the line during a call.

In order to eliminate the above-mentioned drawbacks, the present invention provides a hook switch which is characterized by providing a partition in the recess on the handset side, thereby eliminating careless and erroneous operation of the switch by fingers, etc., and also having a practical attachment/detachment function. This provides a structure to prevent erroneous operation.

This will be explained below with reference to the drawings.

FIG. 4 is a perspective view of the vicinity of the handset side recess according to the present invention. The fitting mechanism itself between the handset 1 and the holder 3 is the same as the conventional one shown in FIGS. 1 to 3. In the structure according to the present invention,
A partition 9 is provided in the recess 8 on the handset 1 side,
The hook switch stored in retainer 3 is numbered 10.
The structure is as shown in . That is, the switch 10 has a slit 11 that fits into the partition 9 on the handset 1 side.

The presence of the partition 9 prevents inadvertent malfunction of the hook switch due to fingers or the like when attaching or detaching the handset 1 or making or receiving calls. Further, the fitting function between the recess 2 and the hook 4 has the same function as the conventional one. As described above, according to the present invention, a practical structure for preventing a lock switch from malfunctioning can be obtained.
