Abstract

The utility model discloses an improved connecting base metal case which belongs to the connectors of the line. The utility model is cladded on a connecting base to prevent the electromagnetic wave from disturbing the signals, metal scraps are punched into a shell body, the shell body is provided with an opening corresponding to a jack of the front end of the connecting base, welding feet fixed with fixing holes of a circuit board are arranged below both sides of the shell body, adjoin at least a groove with the body, can be bent into a circular or triangular equi-solid structure, and are inserted into the fixing holes, so the utility model has excellent welding effect and the value of popularization and application.

Description

Modified model Connection Block metal shell
Technical field
A kind of structural improvement of Connection Block metal shell belongs to the connector class of electricity field circuit.
Background technology
Fast development along with electricity science and technology, various electrical equipment are more and more, for solving the Electromagnetic Interference problem, Connection Block adopts metal shell to prevent Electromagnetic Interference (Fig. 1) more at present, its Connection Block metal shell B, make with the sheet metal punching press, metal shell B front end is provided with a perforate D with respect to the jack C of Connection Block A front end, be provided with in metal shell B two side-lowers and can combine fixing welding foot G with the set fixing hole F of circuit board E, behind the fixing hole F that this welding foot G insertion circuit board E is upward set, with being fixed on the circuit board E after the tin sticky of tin stove, metal shell B is stamped to form with sheet metal, the welding foot G of metal shell B becomes flat, when welding foot G inserts in the fixing hole F on the circuit board E (Fig. 2), it is obviously excessive with the space that welding foot G goes up flat two sides and the distance between fixing hole F wall, the tin sticky fixed effect is not good, metal shell B goes up nickel plating in addition increases gloss, but welding foot G can not tin sticky, ability tin sticky behind the powerful scaling powder of necessary immersion, still can not automated job, must make it adhere to one deck scaling powder earlier with manually taking and to insert tin sticky in the fixing hole F on the circuit board E, so not only loaded down with trivial details, and bad control tin sticky thickness and height, Yi Yin pollutes and makes product can't improve acceptance rate, cost can't reduce, and in a large amount of societies that produce competition, cost can not reduce will have a strong impact on the competitiveness of product on market.
Summary of the invention
The metal shell procedure of processing is loaded down with trivial details in order to solve for the utility model, set fixing hole contacts to pay no attention to think of and pollutes workpiece in the course of processing on welding foot and the circuit board, the shortcoming that can't improve rate of finished products and reduce cost, for improving the market competitiveness, following solution is provided: promptly the adjacent at welding foot and housing main body is provided with at least one groove, it is a stereochemical structure that welding foot can bend, also available following measure realizes that promptly the section of welding foot is U-shaped, circle, triangle, polygon or ellipse; The welding foot surface electrical is coated with one deck tin material.
Advantage of the present utility model and effect are: have characteristics simple in structure, easy to manufacture after the improvement, have better fixed effect than prior art, can significantly improve the acceptance rate of product, and then reduce cost, enhance one's market competitiveness.

Fig. 2 is that welding foot combines schematic diagram with circuit board in the existing structure
Fig. 3 is stereo appearance figure of the present utility model (before welding foot is not crooked) schematic diagram
Fig. 4 is a scheme of installation of the present utility model
Fig. 5 is that the utility model welding foot combines schematic diagram with circuit board

Embodiment
By Fig. 3, Fig. 4 as can be known, the utility model modified model Connection Block metal shell, mainly be to be coated on the Connection Block 1, it is reached prevent that electromagnetic wave from producing interference to signal, housing main body 2 is to make with Metal Flake material punching press, be provided with a perforate 5 with respect to Connection Block 1 front end jack 4 places on the housing main body 2, two side-lowers on housing main body 2 are provided with and can combine fixing welding foot 6 with the set fixing hole 8 of circuit board 3, improvement of the present utility model is: welding foot 6 is provided with at least one groove 7 (Fig. 3) with housing main body 2 adjacents, make welding foot 6 be stereochemical structures (Fig. 4) such as circle and triangle by crooked folding, when welding foot 6 inserts in the fixing hole set on the circuit board 38, the space that the outer rim of welding foot 6 and fixing hole are 8 can dwindle (Fig. 5), can obtain better welding fixed effect, housing main body in the described prior art structure of leading portion 2 is earlier through doing secondary nickel plating program at welding foot 6 again after one nickel plating program again, can omit prior art picks powerful scaling powder with the workpiece of manually taking operation sequence, only zinc-platedly not only can increase output, and can avoid workpiece in the process of taking, to be polluted, effectively improve the acceptance rate of product, reduce production costs, improve the competitiveness on market; In structure of the present utility model, the welding foot 6 with stereo shaping structure can also make other geometric modelings (as polygon, ellipse) except the circle described in identical text, triangle (Fig. 6) and U-shaped (Fig. 7) again.
In sum, the utlity model has simple in structure, the characteristics that are easy to make, has better welding fixed effect than existing product, easy to process, increase substantially product quality, reduce cost and improve the advantage of sales rate, and the utility model does not see any publication or public occasion before application.
