Detailed Description
The utility model is described in detail below with reference to the accompanying drawings. As shown in fig. 1 to 3.
Example 1: referring to fig. 1, a metal shielding case includes: the annular sleeve 1, the side of annular sleeve 1 is equipped with at least one axial setting's clearance 3, and the both sides of clearance 3 are main connecting portion 12 and vice connecting portion 13 respectively, are connected with the elastic connection piece 2 that the multi-disc interval set up between main connecting portion 12 and the vice connecting portion 13.
When the metal shielding sleeve is manufactured, the sheet is adopted, the elastic connecting piece 2 is punched at one end of the sheet, then the sheet is bent to be round, and the outer end part of the elastic connecting piece 2 is welded with the other end of the sheet, so that the metal shielding sleeve is formed. When the sleeving is completed, the elastic connecting sheet 2 is retracted, the inner diameter of the metal shielding shell is reduced, and the metal shielding shell is tightly sleeved with the electronic connector.
See fig. 1, 2; further, the elastic connection piece 2 has a wave shape.
The wavy elastic connecting sheet 2 has certain elasticity, and can stretch and retract in a short distance, so that the inner diameter of the metal shielding sleeve is temporarily increased, and the sleeve is convenient to sleeve.
See fig. 3; further, the elastic connecting piece 2 is square-wave-shaped.
The elastic connecting piece 2 is provided with a square wave shape, so that the elastic connecting piece 2 has elasticity and can stretch and retract for a short distance.
Further, one end of the elastic connecting piece 2 is integrally formed with the main connecting portion 12, the other end of the elastic connecting piece 2 is provided with a clamping portion 21, and the auxiliary connecting portion 13 is provided with a clamping hole 16 matched with the clamping portion 21.
In order to prevent the elastic connecting piece 2 from separating from the main connecting part 12 or the auxiliary connecting part 13 in the using process, the technical scheme adopts the technical scheme that a clamping hole 16 is formed in the auxiliary connecting part 13; when the shell is specifically manufactured, the shell is processed by a sheet, and one end of the sheet is stamped to form the elastic connecting sheet 2, so that the elastic connecting sheet 2 and the main connecting part 12 are integrally formed; the other end of the sheet is punched to form a clamping hole 16 matched with the clamping part 21 of the elastic connecting sheet 2, the sheet is bent and molded, and the clamping part 21 is clamped into the clamping hole 16; ultrasonic welding may be performed as necessary. By providing the engaging portion 21 and the engaging hole 16, the welding area can be increased.
Further, the clamping portion 21 includes a main card 23, and a plurality of auxiliary cards 22 are respectively arranged on two sides of the main card 23; the clamping hole 16 comprises a main clamping groove 14 matched with the main card 23, and auxiliary clamping grooves 15 matched with the auxiliary cards 22 are respectively arranged on two sides of the main clamping groove 14.
By providing the main card 23, the sub card 22, and the like, the connection area between the engaging portion 21 and the sub connection portion 13 is increased, and the connection stability is improved.
Further, a plurality of hollow grooves 11 are formed in the side face of the annular casing 1 at intervals.
The hollow groove 11 is arranged, so that the material consumption is reduced, and the cost can be reduced; secondly, the annular casing 1 is provided with a certain elasticity.
The foregoing is merely exemplary of the utility model, and those skilled in the art will recognize that the utility model is not limited thereto, except insofar as modifications may be made by those skilled in the art in light of the teachings of the utility model.
