Problems solved by technology
[0004] However, the use of rubber plugs for waterproofing has the following problems: frequent opening and closing of rubber plugs will cause wear and tear, resulting in poor sealing performance and weakened waterproof effect
Opening and closing will not be easy
And it is easy to forget to plug or not completely plugged, so that the purpose of waterproofing cannot be achieved.

The invention relates to a terminal matched with an electrical signal transmission device in use and provided with an electrical signal transmission interface. The terminal comprises a switching circuit used for controlling whether an internal circuit and a metal contact are connected or disconnected. The metal contact comprises a switching control pin. The electrical signal transmission device is correspondingly provided with a power-on pin which is electrically connected with the switching control pin to provide a switch-on signal. When the switching control pin receives the switch-on signal, the internal circuit and the metal contact are connected. When the switching control pin does not receive the switch-on signal, the internal circuit and the metal contact are disconnected. When metal contacts are connected due to water or other causes, the internal circuit will neither be burned out nor function abnormally due to short circuit. Thus, injection molding can be carried out directly at the interface to expose the metal contact, and there is no need to use a waterproof rubber plug for water proofing. Compared with the traditional waterproof design, the terminal has advantages such as easier use and higher reliability.
Description
technical field [0001] The invention relates to the electric communication technology, in particular to a terminal with an electric signal transmission interface used in conjunction with an electric signal transmission device. Background technique [0002] In the handheld terminal, in order to facilitate charging and data transmission, etc., a matching base is generally designed. The connection between the base and the handheld terminal adopts the method of elastic thimble (pogopin), that is, a bare metal contact is designed on the handheld terminal, and an elastic thimble is designed at the corresponding position of the base. When the handheld terminal is inserted into the base, the elastic thimble contacts with the metal contact to form a circuit, realizing functions such as charging and data transmission. [0003] Since handheld terminals, especially industrial-grade handheld terminals, generally have higher waterproof requirements, such as IPX4, IPX5, IPX6, IPX7, etc., ...
