Description
TECHNICAL FIELD
[0001] The present application relates to an electrical connector, in particular to a high-vibration-resistant modular transmitter electrical connector and a mounting method thereof. BACKGROUND
[0002] In the field of industrial automation, instruments and sensors, the electrical connector is a core component for signal transmission and power connection, and its reliability directly affects the overall performance of the equipment. The traditional electrical connector is connected with the metal shell through mechanical assembly or adhesive, and has the following key defects: First, the product stability is insufficient: the current pressure transmitter connector is usually a standard Hesman connector, which is matched with nuts, sealing rings and other ways to form an assembly structure with the metal shell. Such structure is prone to nut loosening and electrical interface failure under high vibration (such as 20g vibration).
[0003] Second, the protection performance is low: the protection of traditional standard Hesman electrical interface and M12x1 electrical interface is only IP65. Because the interface part is a standard product, the waterproof and breathable film position can only be fixed on the front of the electrical interface, which has no protection when contacting with the outside world, and there is a risk of water ingress.
[0004] Third, the sealing performance is limited: the traditional scheme needs to additionally add O-ring, sealing glue or gasket at the interface of metal shell-plastic connector to achieve the protection level. However, the multi-stage sealing structure not only increases the material cost and assembly complexity, but also has the risk of aging: the rubber sealing element is easy to be affected by oil stains and ultraviolet light, which hardens and cracks, and the liquid sealing glue has the problems of uneven solidification and poor material compatibility, which will affect the sealing performance of the pressure transmitter.
[0005] Fourth, the demand diversity and physical specifications are various, and the modularization cannot be realized: because the traditional A-type and C-type four-core connectors and metal and plastic M12x1 aviation plug structures are different, the corresponding metal shell structures are also different, which leads to complex material management and increased material cost.
[0006] Fifth, the production processes of different connectors are different, and the resource allocation is different, resulting in more required resources: because the structures of traditional A-type and C-type four-core connectors and M12x1 aviation plugs are different, the assembly processes are also different, and the materials, stations and equipment configurations involved are different, resulting in more required resources.
