Abstract

A keystone jack (10) includes a cover body (1), a lining body (2), a carrier body (3), a printed circuit board (4), a housing (5), and a flap (6). The cover body (1) includes a space (11). The space (11) includes a cruciform partition with an elongated partition plate (13) perpendicular interlaced a short partition plate (14). The lining body (2) has two edges (21). A connection part (22) is between the two edges (21). A stud (23) and a separation plate (24) are between the connection part (22) and the two edges (21). The stud (23) has a first channel (231). The separation plate (24) has a second channel. When the lining body (2) is installed in the space (11), the elongated partition plate (13) and the short partition plate (14) in the space (11) are through the first channel (231), the second channel (242), and the opening (25) to form a double-cross isolation structure. When the keystone jack (10) is used, the electricity is more stable, and the crosstalk interferences are decreasing, and the impedance is more stable, and the electronic signals are not decayed.

Claims

1. A keystone jack (10) including comprising:

a cover body (1) including a space (11) formed between two sidewalls (cc), the cover body (1) including a bottom surface (111), an elongated partition plate (13) formed on the bottom surface (111), the elongated partition plate (13) perpendicularly interlacing a short partition plate (14), the short partition plate (14) including a bottom part (141), extending a distance (15) from the bottom surface (111);

a lining body (2) installed in the space (11), the lining body (2) having two symmetrical edges (21), a connection part (22) formed between the two edges (21), the connection part having a stud (23), including a first channel (231), a separation plate (24) being arranged between the two edges (21), the separation plate (24) including a convex wall (241) including a second channel (242) opposite the first channel (231), an opening (25) formed between the separation plate (24) and the connection part (22);

wherein when the lining body (2) is installed in the space (11), the elongated partition plate (13) is accommodated in the first channel and the second channel and the short partition plate (14) is accommodated in the opening.

2. The keystone jack (10) in claim 1, further comprising a joining part (12) having a barb shape is provided on each of the four corners of the space (11).
