Description

Technical Field

[0001] The present invention relates to the technical field of special-shaped structure wires, and in particular to a special-shaped structure ultra-high-speed high-frequency wire. Background Art

[0002] Special-shaped ultra-high-speed high-frequency cables (hereinafter referred to as cables) generally refer to cables with non-traditional geometric shapes and characteristics. They are used to transmit high-speed data signals or high-frequency electrical signals and have the characteristics of high frequency response, low loss, good shielding effect and superior mechanical properties.

[0003] The structure of existing wires usually includes conductors, insulation layers, drain wires and shielding coatings, such as Figure 1 As shown, the conductors are symmetrically arranged on both sides, the insulation layer is coated on the conductors, the drain wires are symmetrically arranged and located on either side of the symmetrical conductors, and the shielding coating layer (the shielding coating layer is composed of an internal shielding layer and an external coating layer) is coated outside the insulation layer and the drain wires. The axis of the drain wire and the axis of the conductor are coplanar. This arrangement is beneficial for improving signal transmission stability and reducing electromagnetic interference. However, during use, the drain wire of existing wires is prone to displacement when the wire is subjected to force or bending, which reduces the stability of signal transmission. In addition, when in use, the end of the wire has an external connection portion for connecting to an external device. Currently, wires with external connections are connected to the conductor, drain wire, and external connection portion by welding or crimping. When connected, the shielding coating at the end of the wire peels off. The existing external connection portion is difficult to quickly connect to the wire and fully ensure that the relative position of the conductor and drain wire is stable and reliable. On the one hand, this reduces the convenience and efficiency of manufacturing wires with external connections. On the other hand, the change in the relative position of the conductor and drain wire reduces the stability of signal transmission during use of the wire. Summary of the Invention

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] See also Figure 2 and Figure 3 A special-shaped ultra-high-speed high-frequency wire includes a wire body 1, which includes a conductor 102 wrapped with an insulating layer 101, an inner layer 103 symmetrically provided with slots 104, a drain wire 105, and a shielding coating 106. Figure 2 As shown, the conductors 102 are symmetrically distributed on the left and right, the inner layer 103 is coated on the insulating layer 101 of the symmetrical conductor 102, the slots 104 are symmetrical on the left and right, the drain wires 105 are respectively embedded in the slots 104, and the drain wires 105 and the axis of the conductor 102 are on the same horizontal plane, the shielding coating 106 is coated on the inner layer 103, and the drain wires 105 are clamped by the slots 104 to prevent the drain wires 105 from moving up and down. It also has the effect of reducing the width of the wire, effectively improving the stability of the wire during use. Among them, the inner layer 103 plays the role of fixing and protecting the insulating layer, increasing the mechanical stress of the wire, and reducing the changes when the wire is bent. The inner layer 103 can be made of polyethylene material with low dielectric loss. A plurality of channels 107 are opened on the insulating layer 101, and the plurality of channels 107 are evenly distributed along the circumference of the insulating layer 101 to form a lotus root-like structure, which can reduce the amount of wire used.

[0025] See Figure 2 、 Figure 4 、 Figure 5 and Figure 6The end of the line body 1 is connected to the profiling medium end 2, and the profiling medium end 2 is sleeved with an external joint 3. The profiling medium end 2 includes a clamping body 21 that is symmetrical and connected to the upper and lower sides and slides up and down. An elastic member 22 is provided between the clamping bodies 21. When no external force is applied, the symmetrical clamping bodies 21 are in an outwardly stretched state under the action of the elastic member 22, that is, Figure 4 As shown, there is a certain distance between the upper and lower symmetrical clamping bodies 21, and the opposite surfaces of the clamping bodies 21 are provided with a limiting groove 1 23 corresponding to the conductor 102, a limiting groove 24 corresponding to the insulating layer 101, a limiting groove 3 25 corresponding to the shielding coating 106, and a limiting groove 4 26 corresponding to the drain line 105. The limiting groove 1 23, the limiting groove 24 and the limiting groove 3 25 on the clamping body 21 are distributed in sequence from front to back along the axial direction of the conductor 102. In the connected state, the conductor 102 is clamped and fixed and limited by the upper and lower symmetrical limiting groove 1 23, and the upper and lower symmetrical limiting groove 2 24 is used to clamp and limit the conductor 102. The insulating layer 101 is clamped, fixed and limited, the upper and lower symmetrical limiting grooves 25 are clamped, fixed and limited, and the upper and lower symmetrical limiting grooves 26 are clamped, fixed and limited. The drain wire 105 is clamped, fixed and limited. On the one hand, the wire body 1 and the clamping body 21 are stably fixed together, and on the other hand, the conductor 102 and the drain wire 105 maintain a stable and reliable relative position relationship, thereby improving the stability of the wire material. In the manufacturing process, the clamping body 21 in the outward state facilitates the rapid placement of the conductor 102, the insulating layer 101, the drain wire 105 and the shielding coating 106 in the corresponding positions.

The connecting heads 34 pass through the base 31 backward to the limiting groove 5 32 and the connecting heads 34 correspond to the conductor 102 and the drain wire 105 one by one. The locking assembly 33 fixes the clamping body 21 and the base 31 together. During the connection process, when the conductor 102, the insulator 101, the drain wire 105 and the shielding coating 106 are quickly placed in the corresponding positions in the outward clamping body 21, and then the symmetrical clamping body 21 is initially pressed, the drain wire 105 and the conductor 102 are at this time. The front ends are all placed in front of the front end surface of the clamping body 21, and then the base body 31 is put on, so that the symmetrical clamping body 21 enters the limiting groove five 32, and the limiting groove five 32 limits the clamping body 21 to further clamp the symmetrical clamping body 21, and reaches the preset position after the front ends of the drain line 105 and the conductor 102 are against the corresponding connecting head 34, and then the base body 31 and the clamping body 21 are fixedly connected together by the locking assembly 33, so that the drain line 105 and the conductor 102 maintain a stable and reliable positional relationship, and at the same time, the drain line 105 and the conductor 102 are in a stable connection state with the corresponding connecting head 34, and the connecting head 34 is used to connect the conductor 102 and the drain line 105 to external equipment.

[0027] See Figure 4 、 Figure 6 and Figure 7 The locking assembly 33 includes an automatic buckling portion 331 and a tightening reinforcement portion 332. The automatic buckling portion 331 automatically connects the symmetrical clamping body 21 to the base 31 when the base 31 is sleeved to the preset position of the clamping body 21, and then the tightening reinforcement portion 332 further tightens the symmetrical clamping body 21, further improving the firmness and stability of the clamping of the clamping body 21. The automatic buckling portion 331 includes a connecting piece 3312 that is slidably connected to the buckle joint 3311 left and right, a buckling seat 3313 fixedly installed on the base 31, and a press-unlocking piece 3314 that is slidably connected to the base 31 up and down. The connecting piece 3312 is fixedly installed on the clamping body When the cam 3314 is in the unlocking state, the cam 3314 is in the unlocking state, and ... Figure 7As shown, the unlocking is completed by pressing the unlocking piece 3314 to limit the snap joint 3311 so that the snap joint 3311 moves out of the snap seat 3313.

[0028] See Figure 6 The tightening reinforcement part 332 includes a threaded member 3322 rotatably connected to a tightening head 3321. The threaded member 3322 is symmetrically distributed and threadedly connected to the base 31. The tightening head 3321 is slidingly connected to the base 31 and is in direct contact with the clamping body 21. Rotating the threaded member 3322 causes the tightening head 3321 to move downward and tighten against the clamping body 21, further improving the stability and firmness of the clamping and fixing of the clamping body 21.

[0029] See Figure 6 The connecting pieces 3312 correspond one-to-one to the symmetrical clamping bodies 21, and the connecting pieces 3312 on the symmetrical clamping bodies 21 are symmetrical to each other. The opposite side of the symmetrical connecting pieces 3312 is a pressing area. During the processing, the pressing area of ​​the connecting piece 3312 can be pressed at the same time to complete the initial clamping and fixing of the clamping body 21.

A plurality of raised wedge-shaped areas 27 are provided on the clamping body 21. The wedge-shaped portions 321 correspond to the wedge-shaped areas 27 one by one. The wedge-shaped portions 321 and the wedge-shaped areas 27 cooperate to limit the clamping body 21, so that the clamping body 21 can be inserted into the limiting groove five 32 quickly and smoothly.
