Abstract

The utility model relates to a clamp able to filter wave, comprising two clamp units. The clamp units comprises two casing seats and two electromagnetic elements, the electromagnetic elements are respectively placed into the containing space of the casing seat, the clamping block of the containing space is clamped into the clamping slot of the electromagnetic elements, then the two clamp units are mutually buckled together, each buckling block is buckled into each buckling ear, baffles are clamped on the outer wall surface of the casing seat to make that the casing seats are buckled and fixed, two contacting surfaces of the electromagnetic elements are closely contacted to obtain excellent filtering effect, and because the electromagnetic elements and top holding sheets are arranged in the line contact, the magnetic leakage phenomenon can be prevented simultaneously.

Description

But the anchor clamps of filtering

The utility model relates to a kind of filter, but refers to the anchor clamps of the filtering on a kind of input cable that is installed on the video signal acoustic product especially.

But the anchor clamps 10 of existing filtering as shown in Figure 1, 2, 3, can be installed on the input cable 11 of video signal acoustic product, and it is to be made of integrated housing 12 and two electromagnetic components 14; Wherein this housing 12 is combined by two

halves housing

16,18, utilize brace 13 that it is connected into one in 16,18 of two halves housings, these half housing, 16 1 ends are provided with two fastening holes 15, second half housing 18 1 ends are provided with two card protuberances 17, be positioned at two halves housing 16,18 bottoms and be provided with two top holding pieces 111, the end of this top holding piece 111 is provided with a round convex grain 112, in the two halves housing 16,18 of respectively electromagnetic component 14 being packed into.When but the anchor clamps 10 of filtering are held on the cable 11, with 16,18 pressings of two halves housing, card protuberance 17 are buckled in fastening hole 15 get final product again.Though but the anchor clamps 10 of this filtering can reach the effect of filtering, yet have following shortcoming:

1, easily cause between the two halves housing about distortion, make two electromagnetic components produce the gap, and then the magnetic leakage phenomenon take place, so can't reach the effect of filtering.

2, the round convex grain of top holding piece and contact area between electromagnetic component are to contact, and easily roll, and then reduce the effect of filtering.

3, the two halves housing after covering does not have the gap design, causes two halves housing mutual extrusion, easily causes and forms the gap between electromagnetic component.

In view of this, the inventor is the shortcoming that overcomes prior art, and on the clamp structure basis of above-mentioned filtering, development and Design is constantly tested energetically, but successfully develops the anchor clamps of the filtering of innovation fully finally.

Main purpose of the present utility model, but be to provide a kind of anchor clamps of filtering, so as to improving the close contact between two electromagnetic components, so that the noise and the noise phenomenon that reduce video product significantly and produced, and then improve competitiveness of product.

For this reason, the utility model adopts following technical scheme:

But a kind of anchor clamps of filtering, it is characterized in that it being to constitute by two fixture units, this fixture unit includes a shell block and an electromagnetic component, this shell block is provided with a spatial accommodation, on two relative internal faces of spatial accommodation, be provided with fixture block, on other two relative internal faces, be provided with semi-circular hole, be provided with several double wedges in semi-circular hole, be provided with two top holding pieces of Zhe in addition in the shell block bottom, this top holding piece has the angle of upwards steeving, and be provided with a wire bead in the end of top holding piece, a side of this shell block is provided with two buckle ears, and is provided with two catch and two binding blocks in another side.When two fixture units are buckled into one mutually, can make it reach 4 effects that are fastened, make two contact-making surfaces of electromagnetic component contact closely, again because of contacting for line between electromagnetic component and top holding piece, can avoid rolling of electromagnetic component, and then obtain good filtering effect.

The utility model embodiment is described in detail as follows in conjunction with following accompanying drawing:

But Fig. 1 is the anchor clamps of existing filtering uses scheme of installation.

But Fig. 2 is the anchor clamps schematic perspective view of existing filtering.

But Fig. 3 is the cross section view of the anchor clamps of existing filtering.

Fig. 4 is a three-dimensional combination schematic diagram of the present utility model.

Fig. 5 is a perspective exploded view of the present utility model.

Fig. 6 is a profile of the present utility model.

See also shown in Fig. 4,5,6, but the anchor clamps 20 of the utility model filtering, it is to be made of two fixture units 21, this fixture unit is made up of two shell blocks 30 and two electromagnetic components 40, wherein, this shell block 30 is provided with a spatial accommodation 31, electromagnetic component 40 can be inserted in the spatial accommodation 31, is provided with a fixture block 32 in the opposed inner walls face of spatial accommodation 31; And be provided with semi-circular hole 33 in other two relative internal faces, be provided with several double wedges 34 in semi-circular hole 33, make it can bite the crust of cable, be provided with two top holding pieces 35 of Zhe in addition in shell block 30 bottoms, this top holding piece 35 has the angle of upwards steeving, be provided with a wire bead 36 in the end of top holding piece 35, the side in shell block 30 is provided with two buckle ears 37 again, is provided with two catch 38 and two binding blocks 39 in another side.

This electromagnetic component 40 is provided with a semi-circular groove road 41, and it can be coated on cable in two electromagnetic components; In addition slot 42 is arranged on two sides, it can engage with above-mentioned fixture block 32.

Respectively electromagnetic component 40 is placed in the spatial accommodation 31 of two shell blocks 30, can make fixture block 32 snap into slot 42 internal fixation, and the bottom of this electromagnetic component 40 is that line contacts with 35 of two top holding pieces, when two fixture units 21 are buckled into one mutually, even each binding block 39 buckles in each buckle ear 37, and simultaneously catch 38 is held on the outside wall surface of shell block 30, makes the utility model reach at 4 and be fastened, make two contact-making surfaces of electromagnetic component 40 contact closely.Again because of forming a gap 311 behind two fixture units, 21 fastenings, this gap 311 can confirm that more two electromagnetic components 40 have close contact, and then the acquisition good filtering effect, again because of 35 of electromagnetic component 40 and top holding pieces for line contacts, thereby prevent the generation of magnetic leakage phenomenon.
