Embodiment

As shown in Figure 2, the housing for electronic installation of an embodiment of the present utility model, the coupling end of the coupling end and the 2nd housing 4 that comprise the first housing 3 and the 2nd housing 4, first housing 3 is formed interferes.

Specifically, the angle of inclination 42 that the coupling end that the coupling end of the first housing 3 has the first inclined-plane the 31, two housing 4 has the 2nd inclined-plane 41, inclined-plane the 41, two is greater than the angle of inclination 32 on the first inclined-plane 31, as shown in Figure 3, the contact part on the first inclined-plane 31 and the 2nd inclined-plane 41 is formed and interferes.

By interfering formation to closely cooperate, eliminate gap between housing, improve the stopping property of housing, thus improve waterproof and dustproof and the ESD performance of electronic installation.

In the present embodiment, the angle of inclination 42 on the 2nd inclined-plane 41 is 90 degree.

First housing mentioned here, the 2nd housing can be discrete parts, such as, to slotting upper cover, Xia Gai; Parts can also be injected into, by the upper cover of hinge or gemel connection and Xia Gai, rotate upper cover or the two button is closed by lower lid.

As shown in Figure 4, the housing for electronic installation of another embodiment of the present utility model, the coupling end of the first housing 5 and the coupling end of the 2nd housing 6 connect to be formed by card and interfere.

Specifically, the cross section of the coupling end of the first housing 5 is fusiform, and the coupling end of the 2nd housing 6 is provided with groove, and fusiform side 51 forms interference with outer side wall 61 and the inner side-wall 62 of groove.

When the fusiform coupling end of the first housing 5 is installed in the groove of the 2nd housing 6, as shown in Figure 5, fusiform side 51 forms interference with outer side wall 61 and the inner side-wall 62 of groove, eliminate gap between housing, eliminate gap and formation tortuous cooperation path between housing, improve the stopping property of housing, thus improve waterproof and dustproof and the ESD performance of electronic installation.

Certainly by the different designs of the coupling end of the first housing 5 and the shape of groove, only can also form interference with outer side wall 61 in fusiform side 51, or fusiform side 51 is only formed with inner side-wall 62 interferes, and associated viscera belongs to routine techniques, no longer describes in detail here.

The thickness of inner side-wall 62 can be less than the thickness of outer side wall 61, and thickness difference interferes the distortion amount produced also not identical, and the thickness of inner side-wall 62 is little, it is easier to distortion, and the thickness of outer side wall 61 is big, being not easily out of shape, the distortion that can reduce outer side wall 61 like this is on the impact of product design.

The coupling end of the first housing 5 can also adopt other shapes, such as wedge shape, interferes as long as can be formed with the outer side wall 61 of groove and/or inner side-wall 62, and this is not restricted by the utility model.

The one or both sides of groove have guiding surface, are easy to be inserted in groove by fusiform or the wedge shape coupling end of the first housing 5, and in the present embodiment, the both sides of groove have guiding surface 63, as shown in Figure 4.

The both sides of groove have guiding surface 63, and the angle of inclination of guiding surface 63 can be identical, it is also possible to different, in the present embodiment, the angle of inclination of guiding surface is identical.

As shown in Figure 5, the arranged outside of the coupling end of the first housing 5 has flange 53, flange 53 contacts with the end of the outer side wall 63 of groove, the path formed between housing is in Fig. 5 shown in dotted line, therefore steam, dust enters from hull outside needs that more grow, more tortuous path inside housing, improves waterproof and dustproof and the ESD performance of electronic installation further.

As shown in Figure 6, the housing for electronic installation of another embodiment of the present utility model, groove can be multiple, correspondingly the cross section of the coupling end of the first housing 7 is multiple fusiform, in the present embodiment, the cross section of the first housing 7 coupling end is two fusiforms, and correspondingly the 2nd housing 8 coupling end is provided with two grooves.

Each fusiform side 71, forms interference with the outer side wall 81 of groove with inner side-wall 82, thus defines path longer, more tortuous between housing, improves waterproof and dustproof and the ESD performance of electronic installation further.

Part in the middle of two grooves is provided with recess 83, reduces the thickness of groove inner side-wall 82 so that the inner side-wall 82 of two grooves is easier to distortion, reduces the distortion of outer side wall 81.

The utility model also provides a kind of electronic installation, comprising: the above-mentioned housing for electronic installation of circuit card and containment circuit board, such as gateway module, car body control module (BodyControlModule, BCM) etc.

Although the utility model discloses as above with better embodiment, but the utility model is not defined in this. Any those skilled in the art, not departing from the various change and amendment done in spirit and scope of the present utility model, all should include in protection domain of the present utility model, and therefore protection domain of the present utility model should be as the criterion with claim limited range.
