[0031] The first embodiment of the present application provides a first electronic filter, referring to Figures 1-3The electronic filter includes an outer frame 100, a liquid crystal assembly 200, a first connector 300 and a second conductive part 400. An edge area of the outer frame 100 is provided with a mounting part 110. The outer frame 100 includes a first frame body 120 and a second frame body 130. The first frame body 120 is arranged opposite to the second frame body 130. The liquid crystal assembly 200 is arranged between the first frame body 120 and the second frame body 130. The liquid crystal assembly 200 includes a first substrate 210, a second substrate 220 arranged on one side of the first substrate 210, and liquid crystal 230 arranged between the first substrate 210 and the second substrate 220. An edge area of the first substrate 210 is provided with a first conductive part 211. The first connector 300 is arranged in the mounting part 110. The second conductive part 400 is electrically connected with the first conductive part 211 and a conductive probe 310 of the first connector 300. Specifically, the mounting part 110 is a slot 111 formed on an outer surface of the second frame body 130. The first connector 300 is arranged in the slot 111.

[0032] The electronic filter of the conventional scheme includes a housing, a liquid crystal assembly 200 arranged in the housing, a connecting wire and a circuit board. A connector of the circuit board is connected with the liquid crystal assembly 200 through the connecting wire. Since the electronic filter of the conventional scheme needs to additionally arrange the connecting wire and the circuit board for mounting the connector, the cost of the electronic filter is relatively high. Therefore, the electronic filter is provided. The electronic filter includes the outer frame 100, the liquid crystal assembly 200, the first connector 300 and the second conductive part 400. The slot 111 is arranged on a surface of the second frame body 130 away from the first frame body 120 of the outer frame 100. The first conductive part 211 is arranged on an edge area of the first substrate 210 of the liquid crystal assembly 200. The first connector 300 is arranged in the slot 111. The second conductive part 400 is electrically connected with the first conductive part 211 and the conductive probe 310 of the first connector 300. Compared with the electronic filter of the conventional scheme, the electronic filter of the present scheme does not need the circuit board and the connecting wire, and does not need to additionally arrange the connecting wire and the circuit board, so that the production cost of the electronic filter can be reduced. Since the first connector 300 is arranged in the slot 111, the length of the electronic filter in the first direction is not additionally increased.

[0033] In the embodiment, the slot 111 is formed on a surface of the second frame body 130 away from the first frame body 120. Figure 1

[0034] In the embodiment, the frame body 100 surrounds an edge of the liquid crystal assembly 200.

[0035] In the embodiment, the slot 111 is formed on a surface of the second frame body 130 away from the first frame body 120.​Figure 1 The first frame 120 and the second frame 130 enclose a first accommodating cavity 140, wherein the first conductive component 211 is located in the first accommodating cavity 140, one end of the second conductive component 400 is electrically connected with the first conductive component 211, and the other end of the second conductive component 400 penetrates through the side wall of the second frame 130 and is electrically connected with the conductive probe 310.

[0036] In the embodiment, the first connector 300 is connected with the second frame 130, and the first connector 300 and the second frame 130 are in an integrated structure. Figure 1 The first connector 300 is connected with the second frame 130, and the first connector 300 and the second frame 130 are in an integrated structure. By connecting the first connector 300 with the second frame 130 and making the first connector 300 and the second frame 130 in an integrated structure, the first connector 300 does not need to be assembled with the outer frame 100, thereby reducing the assembly difficulty of the electronic filter.

[0037] In the embodiment, the first connector 300 and the second frame 130 are injection molded into an integrated structure.

[0038] In the embodiment, the second conductive component 400 is injection molded in the outer frame 100.

By setting the first conductive part 211 as conductive contact, the second conductive part 400 as conductive spring, and the conductive spring in abutment with the conductive contact, when the second frame 130 is installed with the first frame 120, the conductive spring which is integral with the second frame 130 can be deformed to extrude the conductive contact, thereby ensuring the stability of the connection between the conductive spring and the conductive contact, and since the conductive spring is in abutment with the conductive contact, the electrical connection between the first connector 300 and the first substrate 210 can be achieved, which does not need to use a connecting wire to be welded with the substrate of the liquid crystal assembly 200, thereby making the assembly of the electronic filter more simple.

[0044] In the embodiment, the first frame 120 and the second frame 130 are fixed by snap connection.

[0045] In the embodiment, the first frame 120 and the second frame 130 are fixed by screw connection.

The first connector 300 is arranged in the notch 112. The second conductive component 400 is electrically connected with the first conductive component 211 and the conductive probe 310 of the first connector 300. Compared with the electronic filter of the conventional scheme, the electronic filter of the present scheme does not need the circuit board and the connecting wire, and does not need to additionally arrange the connecting wire and the circuit board, so that the production cost of the electronic filter can be reduced. Since the first connector 300 is arranged in the notch 112, the length of the electronic filter in the first direction is not additionally increased.

[0049] In the embodiment, the first connector 300 is provided with a second accommodating cavity 320 near one side of the liquid crystal assembly 200, a part of the first substrate 210 extends into the second accommodating cavity 320 through the sidewall of the gap 112, the first conductive part 211 is located in the second accommodating cavity 320, the second conductive part 400 is fixed to the sidewall of the second accommodating cavity 320, and the second conductive part 400 abuts against the first conductive part 211.
