[0031] like Figure 1 The cable TV terminal connection module shown, Figure 2 FIG. 1 is an exploded schematic diagram of the connection module in this embodiment. In the figure, the upper frame cover 3 is connected to the lower frame cover 1 through a first buckle assembly, and the lower frame cover 1 is connected to the socket panel 5 through a second buckle assembly, wherein the printed circuit board 2 is located between the upper frame cover 3 and the lower frame cover 1. In this embodiment, the first buckle assembly and the second buckle assembly have the same structure, both of which include a fixed end face 61 and a fixed buckle 62 for buckling on the fixed end face 61.

[0032] In the attached Figure 3 , Attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7 and attached Figure 8In the figure, different snap-on components are numbered respectively, and different fixed end faces 61 correspond to different fixed buckles 62. Different snap-on components are distinguished by a to f in the above figures. Among them, in the second snap-on component, the fixed buckles 62a, b and c are respectively located on the socket panel 5, and the corresponding fixed end faces 61a, 61b and 61c are located on the lower frame cover 1. Specifically, in order to ensure that the lower frame cover 1 can be stably fixed on the socket panel 5, the fixed end face 61a is located on the upper frame of the lower frame cover 1, the fixed end face 61b and the fixed end face 61c are located on the lower frame of the lower frame cover 1, and the fixed buckles 62a, 62b and 62c are respectively located at the corresponding positions of the socket panel 5. The above three second snap-on components are distributed in a stable triangle on the connection surface between the lower frame cover 1 and the socket panel 5.

Specifically, in order to ensure that the lower frame cover 1 and the upper frame cover 3 can be firmly fixed to each other, the above three first buckle assemblies are firmly triangularly distributed on the connecting surface of the upper frame cover 3 and the lower frame cover 1. Combined with the above first buckle assembly and the second buckle assembly, in order to save the position of the buckle assembly, the fixing end face 61f located on the lower frame of the lower frame cover 1 is located between the fixing end face 61b and the fixing end face 61c also located on the lower frame of the lower frame cover 1; the fixing end face 61a located on the upper frame of the lower frame cover 1 is located between the fixing buckle 62d and the fixing buckle 62e also located on the upper frame of the lower frame cover 1.

[0033] In order to facilitate the removal of the lower frame cover 1 from the socket panel 5, an ejection plate 13 is provided on the fixed end surface 61a of the lower frame cover 1. When the user wants to remove the lower frame cover 1 from the socket panel 5, the user pushes the ejection plate 13 downward to make the fixed end surface 61a disengage from the fixing buckle 62a, and finally takes out the lower frame cover 1.

[0034] The cable TV terminal connection module is mainly used to connect the cable and the connection line of the cable TV, and finally achieve the purpose of transmitting the cable TV signal. The printed circuit board 2 is used for intermediate signal transmission. In this embodiment, after the connection module is installed and fixed, the printed circuit board 2 is located between the upper frame cover 3 and the lower frame cover 1. Figure 4 As shown, one side of the printed circuit board 2 is provided with a radio frequency interface 21 for connecting the connecting wire, and the other side is provided with a nut 23 for fixing the cable, wherein the nut 23 is a fixed square nut 23 specially used for fixing the cable. The side of the printed circuit board 2 provided with the radio frequency interface 21 faces the lower frame cover 1, and the side provided with the nut 23 faces the upper frame cover 3.

[0035] like Figure 5 and Figure 6The structure diagram of the lower frame cover 1 in this embodiment is shown. The lower frame cover 1 is provided with a first connection hole 14 for exposing the RF interface 21. The corresponding socket panel 5 is also provided with a second connection hole 54 for exposing the RF interface 21. The RF interface 21 is exposed on the outer surface of the socket panel 5 through the first connection hole 14 and the second connection hole 54 respectively. An arc-shaped stopper 15 is provided on the inner side of the first connection hole 14 to facilitate the RF interface 21 to pass through the first connection hole 14. In this embodiment, two arc-shaped stoppers 15 are provided. The first connection hole 14 is a circular hole. The two arc-shaped stoppers 15 are symmetrically arranged on both sides of the circular first connection hole 14. The second connection hole 54 is a square hole. An embedded boss 111 is provided on the outer side of the first connection hole 14. The shape of the embedded boss 111 is adapted to the shape of the second connection hole 54. The embedded boss 111 on the lower frame cover 1 is inserted into the second connection hole 54 of the socket panel 5.

[0036] like Figure 7 The figure shows a schematic diagram of the structure inside the upper frame cover 3 in this embodiment. The upper frame cover 3 is provided with a through hole 36 for the cable to pass through. The cable is fixed to the printed board 2 through the through hole 36 on the lower frame cover 1 through the nut 23, and is connected to the RF interface 21 through the printed board 2. Among them, the upper frame cover 3 is provided with a push rod 35 for clamping the printed board 2. When the lower frame cover 1 and the upper frame cover 3 are covered, the push rod 35 on the upper frame cover 3 presses the printed board 2 against the lower frame cover 1. In this embodiment, two push rods 35 are provided. The push rods 35 are arranged on both sides of the upper frame cover 3, and the top of the push rod 35 contacts the printed board 2.

[0037] like Figure 8 As shown, the upper frame cover 3 is also provided with a wire pressing plate 4 for fastening the cable to the upper frame cover 3, and the wire pressing plate 4 fastens the cable to the through hole 36 through a fastener 41. In order to make the lower frame cover 1 and the lower frame cover 1 bracket more tightly combined, the upper frame cover 3 is provided with a through hole, and the lower frame cover 1 is provided with a fixing hole 110. The fastener 41 passes through the wire pressing plate 4 and is fixed on the fixing hole 110 through the through hole to fasten the upper frame cover 3 and the lower frame cover 1. Among them, in order to enable the printed circuit board 2 to be accurately positioned between the upper frame cover 3 and the lower frame cover 1, a limiting hole 24 is provided on the printed circuit board 2. In this embodiment, the limiting hole 24 is semicircular. The fastener 41 passes through the wire pressing plate 4, the through hole of the upper frame cover 3 and the limiting hole 24 of the printed circuit board 2 in sequence, and is finally fixed in the fixing hole 110. In this embodiment, the printed circuit board 2 is fixed by the positioning of the ejector rod 35 and the fastener 41 and the positioning hole 24, without the need to use other tools for fixing, which is more convenient and quick.

[0038] In this embodiment, in order to better position the upper frame cover 3 and the lower frame cover 1 when they are covered, the joint surface where the upper frame cover 3 and the lower frame cover 1 fit together is a step-type setting to prevent sliding between the two. The step-type setting prevents the upper frame cover 3 and the lower frame cover 1 from sliding up and down. In order to prevent the upper frame cover 3 and the lower frame cover 1 from sliding left and right, the lower frame cover 1 is provided with a non-slip boss 17, and the upper frame cover 3 is provided with a non-slip groove 34 that fits with the non-slip boss 17. When the lower frame cover 1 and the upper frame cover 3 are covered together, the non-slip boss 17 is located in the non-slip groove 34 to prevent the upper frame cover 3 and the lower frame cover 1 from sliding.

[0039] In order to facilitate the nut 23 to fix the cable on the printed circuit board 2, a through window 37 is opened on the upper frame cover 3 to facilitate the insertion of tools such as a screwdriver to tighten the nut 23. When the upper frame cover 3, the printed circuit board 2 and the lower frame cover 1 are covered, the position of the through window 37 corresponds to the position of the nut 23 on the printed circuit board 2, and the user can also check the internal situation through the through window 37.
