Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted intelligent cockpits, in particular to a full-pin power socket structure with multiple fixing modes. Background Art

[0002] The automobile industry is developing rapidly. New energy vehicle companies represented by BYD have started to reduce prices, driving the automobile industry to "involve internally", from the past technology and service to the current price and quality. The price reduction of each OEM will pass the price reduction pressure to each supplier. Monopoly suppliers still have the strength to "arm wrestle" with the OEM, but most suppliers can only accept the price reduction requirements of the OEM. This requires each supplier to optimize the design, production, assembly and other links under the premise of ensuring product quality, standardize parts and components, and platformize the design to reduce material costs.

[0003] Traditional car host power sockets are customized according to customer requirements. Even if the appearance of the power socket is standardized, there will be many models because customers require different assembly methods. At the same time, the metal parts that match the power socket are also different: there are sheet metal parts and die-casting parts, which will result in different plastic shells, increase mold costs, and cannot be mass-produced. In addition, the number and position of tinned solder pins used in power sockets for different customers and different platform products of the same customer are also different, which will further increase the variety of products. Suppliers cannot achieve platform management, which also increases product prices invisibly.

[0004] In order to improve market competitiveness and solve the above-mentioned platformization problems, we have proposed a full-pin power socket structure design with multiple fixing methods. The external interface of the power socket is a platformized interface that adapts to the requirements of different OEMs. The plastic shell of the power socket is structurally compatible with three fixing methods: positioning hole fixing, positioning slot fixing and screw fixing, which is suitable for shells with different structures; the tin-plated solder pins adopt a full-pin design, and customers can match the tin-plated solder pins of the power socket according to their different needs to achieve a platformized design. Based on the above analysis, power socket suppliers can make a standardized power socket that adapts to customers with different fixing structures and different requirements for the number of tin-plated solder pins, and achieve large-scale, automated production, thereby improving product quality and reducing prices, and improving product market competitiveness.

[0005] To this end, we propose a full-pin power socket structure with multiple fixing modes. Utility Model Content

[0008] Furthermore, the shell positioning column is arranged on the top of the power socket assembly, and the sheet metal shell is provided with a positioning hole that matches the shell positioning column.

[0009] Furthermore, the power socket assembly is fixed to the sheet metal housing by screws passing through screw holes.

[0010] Furthermore, the sheet metal shell and the sheet metal bottom shell are made of hot-dip galvanized steel plates.
