Detailed Description

The utility model is further described with reference to the following figures and specific embodiments.

As shown in fig. 1-4, in the present embodiment, for convenience of description, the up-down orientation of the intercom when the intercom is vertically placed on the horizontal desktop is taken as the up-down orientation of the intercom, the side of the intercom facing the operator when in use is taken as the front side of the intercom, the corresponding other side is the back side of the intercom, the left-hand direction when the user faces the front side of the intercom is taken as the left side of the intercom, and the corresponding other side is the right side of the intercom.

The intercom interface structure that this embodiment provided includes casing 10 and function connecting seat 20, wherein, the interface has been seted up to the side of casing 10, specifically, the left surface or the right flank of casing 10 are provided with side boss 12, and the interface is located side boss 11, and except this above-mentioned side boss 12 and interface, other structures of casing 10 are the same with the casing structure of conventional intercom, are not the focus of this embodiment, and no longer detailed here.

The interface is provided with a contact terminal 11 (at a position in the figure) electrically connected with a control circuit board of the interphone, and the contact terminal 11 is an electronic component directly available from the market and is not described in detail here. It should be noted that, a corresponding control circuit needs to be arranged on the control circuit board of the intercom matched with the contact terminal 11, and such control circuit is a conventional circuit, and the control circuit board with such control circuit can be selected or customized on the market according to actual needs.

The function connection socket 20 is provided with a contact pin header 21 to be fitted with the contact terminal 11 and a function module 22 electrically connected to the contact pin header 21, wherein the contact pin header 21 is also an electronic component directly available from the market.
