Drawings

In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments described in the present application, and other drawings can be obtained by those skilled in the art without creative efforts.

FIG. 1 is a schematic diagram of the overall structure of an embodiment of the present application;

fig. 2 is an enlarged view at a in fig. 1.

In the figure: 1. a housing; 2. a through hole; 3. a shielding elastic sheet; 4. and (6) connecting the interfaces.

Detailed Description

The present invention will be described in detail below with reference to embodiments shown in the drawings. However, the present invention is not limited to the embodiments, and the structural, method, or functional changes made by those skilled in the art according to the embodiments are all included in the scope of the present invention.

As shown in fig. 1 and 2, a connector housing includes a housing 1 surrounded by four walls, an upper wall, a lower wall, a left wall, a right wall, and a left wall, wherein a mating port 4 is formed at a front end of the housing 1, at least one through hole 2 penetrating the housing 1 is formed at least one outer edge of the housing 1, and the through hole 2 is formed at an outer edge of the housing 1 close to the mating port 4.

In the specific application process, considering that the shell 1 needs to be bent for three times in the forming process to form a whole, therefore, specifically, three outer edges of the shell 1 are provided with the through holes 2 corresponding to the three bending positions, and because the shell 1 is in a cuboid shape and is made of a single metal plate, one edge is connected in a welding or splicing mode, the through holes 2 are arranged on the other three edges of the shell 1, and the situation that the shell 1 is cracked when being bent is avoided as much as possible.

In order to enhance the technical effect, a plurality of through holes 2, preferably three through holes 2, may be provided on each outer edge, and since the strength of the housing 1 itself is affected by the length of one through hole 2 being too long, the plurality of through holes 2 may be selected to avoid the negative effect.

Specifically, be located the setting between three through-hole 2 equidistance on the outer arris of same department, the equidistance interval sets up and plays the stability of guaranteeing casing 1 when the shaping of bending.

In order to improve stability and reliability, after the length and the number of the through holes are controlled, the width of each through hole 2 needs to be controlled, and the extending width of each through hole 2 in the vertical direction and the horizontal direction is the same, so that the stress performance of two sides of the through holes can be evenly distributed in the bending process, certain symmetry is achieved, and the through holes 2 are prevented from deforming in the bending process of the shell 1.

But the extending width can not be too large, after the width is too wide, the overall strength of the shell 1 can be affected, when the repeated test is passed, the width of each through hole 2 extending in the vertical and horizontal directions is controlled to be not more than 110% of the thickness of the shell 1, within the range, the assembly yield after the shell 1 is bent is the highest, and the basic requirements of product production can be met. Too wide an extension will cause the overall strength of the housing 1 to be reduced, and cause process difficulties, too low and difficult to achieve the purpose of opening the hole, and it needs to be controlled within a certain range, and the most suitable extension width is 110% of the thickness of the housing 1 itself.

The utility model discloses in, also there is the requirement to the location of through-hole 2, particularly, be fixed with a plurality of shielding shell fragments 3 on interface 4, shielding shell fragment 3 extends to 1 rear end of casing from interface department 4, forms the extension terminal point, and through-hole 2 on each outer arris of department all sets up within extending the terminal point to the distance to interface 4 foremost, through extending the terminal point and to interface 4 foremost, reaches the effect of restriction through-hole position.

The utility model discloses a be provided with a plurality of through-holes 2 on the outer arris on casing 1 to stamping die avoids the problem of casing 1 fracture when preparing casing 1 to processes such as cutting, bending of metal feedstock, thereby reaches the effect that improves the stability of casing 1 itself, has rational in infrastructure, and material saving improves the effect of the qualification rate of product.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
