The bracket comprises the EMI filter 3 and a casing bracket 2 fixed on a housing of the device, wherein the EMI filter 3 is inserted through a mounting hole 22 formed on the casing bracket 2; an end surface 31 of the EMI filter 3 and a mounting plate 21 are connected through a bolt; the casing bracket 2 comprises the mounting plate 21 that inclines relatively to a casing of the device; and the mounting hole 22 is formed on the mounting plate 21. The mounting plateis arranged obliquely, so that the EMI filter can be installed at any angle, and the bracket is suitable for the electrical device and is especially suitable for the fixation for the EMI filter of thedevices with small thickness and compact internal space, such as a panel TV set, a flat-panel display, and the like.

Description

The support of electromagnetic interface filter

Technical field

The utility model relates to a kind of supporting structure, especially a kind of support of fixedly electrical installation electromagnetic interface filter.

Background technology

At present, the interference that produces for anti-locking apparatus itself enters power line, prevents the work of power line countermeasure set simultaneously, and the incoming end port of the power line of being everlasting is provided with electromagnetic interface filter.But electromagnetic interface filter fixed form, be generally it directly or by being fixed on the parallel or vertical casing that is fixed in device of outer casing stand on the apparatus housing, but this fixed form is arranged the device internal structure and the design of the complete machine appearance poor opposite sex can cause restriction, especially for the influence of panel TV set, the flat-panel monitor equal thickness is little, the inner space is compact electrical equipment.

The utility model content

In order to overcome the deficiency of existing electromagnetic interface filter fixed form, technical problem to be solved in the utility model provides a kind of can avoiding the complete machine internal structure is arranged and the different in nature support that designs the electromagnetic interface filter that impacts of complete machine appearance poor.

The technical scheme that its technical problem that solves the utility model adopts is: the support of electromagnetic interface filter, comprise electromagnetic interface filter, be fixed on the outer casing stand on the apparatus housing, electromagnetic interface filter inserts from the installing hole on the outer casing stand, the end face of electromagnetic interface filter is connected by screw with mounting panel, described outer casing stand comprises and the mounting panel of crust of the device inclination that described installing hole is arranged on the mounting panel.

The beneficial effects of the utility model are: can be by the angle of mounting panel and apparatus housing is set, make electromagnetic interface filter finish installation with angle arbitrarily, thereby itself and device internal structure, appearance design are adapted, avoided the influence that it is arranged the complete machine internal structure and the design of the complete machine appearance poor opposite sex causes.

In order to strengthen the structural strength of support, described support comprises the U type support that is fixed on device inside, and the side plate of U type support both sides is provided with fixed head, and fixed head is connected with the mounting panel of outer casing stand by fixed structure; Electromagnetic interface filter inserts installing hole and snaps in the groove of U type support, and the end face of electromagnetic interface filter, fixed head, mounting panel three connect by screw.By the angle of mounting panel and fixed head and apparatus housing is set, make electromagnetic interface filter finish installation with angle arbitrarily.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the support of electromagnetic interface filter of the present utility model, comprise electromagnetic interface filter 3, be fixed on the outer casing stand 2 on the apparatus housing, electromagnetic interface filter 3 inserts from the installing hole 22 on the outer casing stand 2, the end face 31 of electromagnetic interface filter 3 and mounting panel 21 are connected by screw, described outer casing stand 2 comprises and the mounting panel 21 of crust of the device inclination that described installing hole 22 is arranged on the mounting panel 21.

Owing to need often external power cord to be patched, in order further to improve the structural strength of support, described support comprises the U type support 1 that is fixed on device inside, the side plate 13 of U type support 1 both sides is provided with fixed head 12, and fixed head 12 is connected with the mounting panel 21 of outer casing stand 2 by fixed structure; Electromagnetic interface filter 3 inserts installing hole 22 and snaps in the groove of U type support 1, and the end face 31 of electromagnetic interface filter 3, fixed head 12, mounting panel 21 threes connect by screw.

Concrete, fixed head 12 and fixed structure between the mounting panel 21 comprise the draw-in groove 211 that matches on clamp 121 on the fixed head 12 and the mounting panel 21, the hook groove 212 that matches on grab 122 on the fixed head 12 and the mounting panel 21, it also can adopt other existing fixed structures certainly.

Outer casing stand 2 is the cavity type, form the space that connects the external power source wire terminal by cavity, mounting panel 21 is one of them sidewall of cavity, certainly outer casing stand 2 also can be set to the cavity of projection, outer casing stand 2 by the flanging 23 around its cavity and by screw on the casing of device; U type support 1 is by its bottom surface 11 and by screw, and outer casing stand 2 and U type support 1 also can be existing by other certainly, the mode that adapts with apparatus structure fixes.

Outer casing stand 2 and U type support 1 are connected as a single entity and all are fixed, so fixed head 12 and the mounting panel 21 of outer casing stand 2 and the angle of apparatus housing by U type support 1 is set, because end face 31, fixed head 12, mounting panel 21 threes of electromagnetic interface filter 3 connect by screw, therefore electromagnetic interface filter 3 can be finished installation with angle arbitrarily, thereby itself and device internal structure, appearance design are adapted, avoid the influence that it is arranged the complete machine internal structure and the design of the complete machine appearance poor opposite sex causes, and made things convenient for patching of external power cord.

Because external power cord is when patching, need roll when extracting in the time of especially, in order further to strengthen the structural strength of support, especially strengthen the support when electromagnetic interface filter 3 rocked, the side up and down of described electromagnetic interface filter 3 respectively be arranged on installing hole 22 on the mounting plate 231 of lower limb contact with bottom plate 232, its left and right side contacts with the side plate 13 of U type support 1 both sides respectively.

In order further to strengthen the shield effectiveness of electromagnetic interface filter, described U type support 1 is a sheet metal component, further strengthens shield effectiveness by the metal parcel.
