Description

Foolproof case

The invention relates to a fool-proof casing, in particular to a fool-proof casing which can be used for installing various types of installation parts.

Nowadays, the configuration of electronic devices is becoming more and more complicated, and the assembling process thereof is becoming more and more complicated. If the electronic device is installed in any wrong direction or type when the electronic device is assembled, it may cause the electronic device to fail to function, and it may even burn the electronic device when it is powered on.

In order to avoid this situation, in the existing foolproof casing designs, fixed shapes are usually used for foolproof designs. For example, the foolproof design is made by the shape of the mounting member to be installed in the casing and the mechanical characteristics of the casing. The operator can install a mounting member whose shape matches the mechanical characteristics of the casing to the casing, and avoid installing the mounting member in a wrong manner. However, for mounting parts of different specifications, it is necessary to prepare casings of different specifications. When the expected stock of various specifications of the casing does not match the shipment, it may lead to increased inventory.

In view of the above problems, the present invention proposes a fool-proof casing, so as to respond to a variety of mounting components of different specifications.

An embodiment of the present invention provides a foolproof housing for mounting a first mounting member including a first foolproof recess or a second mounting member including a second foolproof recess. The foolproof casing includes a shell and a foolproof member. The fool-proof element includes a fool-proof bump. The foolproof member is movably disposed on the casing, and the foolproof member includes a first position and a second position. When the fool-proof element is located at the first position, the shell is used for installation of the first mounting member, the fool-proof projection is correspondingly provided at the first fool-proof recess, and the fool-proof projection blocks the second mounting member from being mounted on the casing . When the fool-proof element is located at the second position, the shell is used for mounting the second mounting member, the fool-proof projection is correspondingly disposed on the second fool-proof recess, and the fool-proof projection blocks the first mounting member from being mounted on the casing .

According to the foolproof housing of an embodiment of the present invention, the position of the foolproof bump is changed by moving the foolproof member between the first position and the second position. When the fool-proof element is located at the first position, the fool-proof bump can match the shape of the first mounting element. When the fool-proof element is located at the second position, the fool-proof projection can match the shape of the second mounting element. Therefore, the foolproof case can be matched with the installation of the first mounting member or the second mounting member of different specifications by switching the foolproof member between the first position and the second position. Therefore, a single foolproof enclosure can share mounting parts of different specifications, which can reduce the inventory of the enclosure.
