Protocol converter with anti-interference function

Abstract

The invention dscloses a protocol converter with the anti-interference function, which comprises a machine body. A cover plate is installed on the upper side of the machine body, a concentric-square-shaped sealing strip is arranged between the contact faces of the cover plate and the machine body, a copper plate is embedded in the cover plate, and an inner semiconductor chilling plate is arranged at the bottom of the copper plate; a heat conducting piece is fixed to the side, away from the copper plate, of the inner semiconductor chilling plate, an outer semiconductor chilling plate is arranged on the outer side of the copper plate, a cooling fin set is arranged on the outer side of the outer semiconductor chilling plate, and a cooling fan is installed in the cooling fin set. Heat in the machine body can be dissipated through the heat conducting piece, the inner semiconductor chilling plate, the copper plate, the outer semiconductor chilling plate and the cooling fin set in sequence, heat dissipation can be effectively carried out, meanwhile, heat dissipation holes do not need to be formed in the machine body, the sealing performance of the machine body is guaranteed, and therefore, moisture and dust in the air are difficult to enter the machine body through the heat dissipation holes, and normal operation of the protocol converter is ensured.

Description

technical field [0001] The invention relates to the field of protocol converters, in particular to a protocol converter with anti-interference function. Background technique [0002] Nowadays, with the emergence of various types of converters, the range of use of various instruments has been greatly expanded, making the automatic control system more flexible and adaptable. In this regard, The scope of application of the protocol converter is also very wide. The protocol converter is referred to as co-transfer, also called interface converter, which enables hosts using different high-level protocols on the communication network to still cooperate with each other to complete various distributed applications. Industrial communication requires information sharing and data exchange between multiple devices, and the commonly used communication ports of industrial control devices include RS-232, RS-485, CAN and network. Due to the different interface protocols, the operation and c...

Problems solved by technology

[0003] At present, in order to dissipate heat, the existing protocol converters usually have cooling holes on the body. Although it can effectively dissipate heat and reduce the temperature inside the body, it reduces the sealing performance of the body, and moisture and dust in the air are easy to enter through the cooling holes. Inside the body, the electrical wires inside the body will be damp and dust will accumulate, and poor contact will easily occur, which will affect the normal use of the protocol converter.
