Description

coaxial cable connector

technical field

The utility model relates to a coaxial cable connector, in particular to a connector capable of assembling coaxial cables with different diameters of wires.

Background technique

At present, television reception is mainly based on cable television. The cable TV signal is connected to the receiving TV with a coaxial cable (Coaxial cable). It is not limited to cable TV. Coaxial cables are mainly used for signal transmission. Nowadays, they often have the function of bidirectional transmission of high-frequency signals. They extend from outdoors to indoors, and a connector needs to be installed at the end of the cable to connect with the receiving TV or The distributor is connected to achieve signal transmission; the connector is connected to the docking piece set on the TV or the distributor.

Different requirements for signal transmission quality, the coaxial cable of the same specification has two layers of braiding (Standard), three layers of braiding (Tri-shield) and insulating jacket between the inner insulating layer around the needle-shaped center conductor and the insulating jacket. Different sheathing forms such as four-layer braiding (Quad) will result in different outer diameters of the cables used. In addition, the outer surface of the inner insulating layer has an aluminum foil covering layer to achieve the shielding effect.

In order to cooperate with coaxial cables with different outer diameters, there are various known connector structures. For example, as shown in Figure 1, the connector A at the end of the cable B is mainly composed of an annular nut A 1, a plastic annular body A 2, an inner annular cylinder A 3 and a metal outer circular shaft Formed by ring A 4.

The annular nut A 1 is located on the front side, and has an internal thread inside and is screwed with the docking piece; the plastic annular body A2 is connected with the annular nut A 1, and a waterproof gasket A 21 is provided at the connecting position therebetween; The ring cylinder A 3 is installed inside the plastic ring body A 2 ; the outer circular collar A 4 is sleeved on the side of the plastic ring body A 2 close to the cable B.

When assembling, as shown in Figure 1, after the cable B is stripped, the terminal needle-shaped central conductor B 1 passes through the outer circular collar A 4, and then enters the center of the inner annular cylinder A 3. Afterwards, the outer circular collar A 4 is slid on the plastic ring-shaped main body A 2 through a crimping tool to approach the ring-shaped nut A 1, as shown in Figure 1

A combination of A completes the structure. Because there is enough space between the outer edge A 31 of the buckle part on the side of the inner annular cylinder A 3 and the inner edge A 23 on the side of the plastic annular body A 2, it can accommodate the same specification but the outer diameter of the wire The multi-layer braiding of cables B of different sizes penetrates, and the elastic deformation effect produced by the special shape of the plastic annular body A 2 is used to clamp and seal the cables with different outer diameters. b. For details, please refer to the US Pat.6,848,939 "Coaxial cable connector with integral grip bushing for cables of varying thickness (Coaxial cable connector with integral grip bushing for cables of varying thickness)".

However, after this kind of known connector A is assembled, because the plastic ring-shaped main body A2 is partly exposed (see FIG. 1A), it is prone to aging or oxidative deterioration; therefore, the use of connector A is quite limited. Many, and in actual operation, there are still the following problems and shortcomings:

1. The plastic annular body A 2 is exposed between the annular nut A 1 and the outer circular collar A 4. If it is used outdoors, the plastic ring may be easily damaged after long-term exposure to wind, sun, and rain. The ring-shaped main body A 2 is aged or oxidized and deteriorated, causing damage to the plastic ring-shaped main body A 2 , and water seepage leads to poor contact of the cable B connected to the connector A, which affects the quality of signal transmission and becomes unstable. If the plastic ring-shaped main body A2 is changed to a metal material, it will be very laborious and difficult to use a crimping tool for tight sealing, so it is not welcomed by the market.

2. Between the aluminum foil covering layer insertion port A 32 on the side of the inner annular cylinder A 3 on the side of the annular nut A 1 and the cable insertion port A 41 on the side of the outer circular collar A 4, for There is a long distance, which is approximately equal to the width B 31 (or even longer) of the aluminum foil coating layer after the cable B is stripped, as shown in Figure 1. If this distance is too long, it will not be easy for the internal insulating layer B 2 and aluminum foil covering layer B 3 of the cable B to be inserted in place, which will often cause damage to the internal insulating layer B 2 and aluminum foil covering layer B 3, resulting in When the signal is transmitted in two directions, the reflection loss becomes worse, which affects the quality and stability of signal transmission. In order to improve this problem, it is necessary to shorten the distance between the cable insertion port A 41 of the aluminum foil covering layer insertion port A 32, and this distance is about 2/3 of the width of the aluminum foil covering layer B31 to have an effect. But in this way, the inner diameter of the inner edge A 23 on one side of the plastic annular main body A 2 will be forced by the pressing part A 22 of the plastic annular main body A 2 and the pressing slope A 42 of the outer circular collar A 4 Tight and narrow, so that cable B cannot penetrate.

Furthermore, as shown in Figure 2, another conventional connector D is mainly composed of an annular nut D 1, an inner annular cylinder D 2, an annular main body D 3, and an outer circular collar D 4, and a plastic bushing D 5 constitute. The main difference from the conventional connector A in FIG. 1 is that the plastic bushing D5 is set in the ring-shaped main body D3 and the outer circular collar D4 made of metal, and there is no problem of exposed plastic material.

One side of the annular nut D 1 is connected to the inner annular cylinder D 2 for the needle-shaped central conductor B 1 of the cable B to penetrate, and the annular main body D 3 is sleeved outside the inner annular cylinder D 2 , and One side of the inner annular main body D 2 is provided with a hook portion D 21, and the end of the hook portion D 21 extends from the end face of the annular pressing portion D31 of the annular main body D 3; the annular pressing portion of the annular main body D 3 The outer circular collar D 4 is sheathed outside D 31; the plastic bushing D 5 is set inside the outer circular collar D 4 .

There is a large space between the outer edge D 211 of the clasp at the side end of the inner annular cylinder D 2 and the inner edge D 51 on the side of the plastic bushing D 5 , which can accommodate cables of the same specification but with different diameters. The multi-layer braiding of the wire B penetrates, and the elastic deformation effect of the plastic sleeve D5 can be used to properly clamp and seal the cable B of different thickness.

In the structure of the connector D at the end of the cable line B, since the ring-shaped main body D 3 is made of metal, and its ring-shaped pressing part D 31 and the outer circular collar D 4, it is necessary to use a crimping tool when assembling For pressing and closing, because they are all made of metal, and the length of the pressing distance D 32 is relatively long, it is necessary to apply a considerable force of pressing to push the outer circular collar D 4 relative to the annular pressing part D 31 Crimping is tightened by pressing the distance D32 to complete the crimping, resulting in a time-consuming and laborious crimping operation.

Into, between the aluminum foil covering layer insertion port D22 on the side of the inner annular cylinder D 2 on the side of the annular nut D 1 and the cable insertion port D 41 on the side of the outer circular collar D 4 , There is a long distance, which is longer than the width B 31 of the aluminum foil covering layer after the cable B is stripped. If this distance is too long, it will cause the inner insulating layer B 2 of the power supply cable B and the aluminum foil covering layer B 3 to be opposite. Bit insertion is not easy, often causing damage to the inner insulation layer B2 and aluminum foil coating layer B3. Especially, when high-frequency signals are bidirectionally transmitted, such damage will lead to poor reflection loss and affect the quality and stability of signal transmission. To improve this problem, it is necessary to shorten the distance between the insertion port D 22 of the aluminum foil coating and the insertion port D 41 of the cable, and this distance is about 2/3 of the width B 31 of the aluminum foil coating to be effective. However, in this way, the inner diameter of the inner edge D 51 on one side of the plastic bushing D 5 will be tightened due to the tightening inclined surface D 52 of the plastic bushing D 5 and the tightening inner hole inclined surface D 33 of the annular main body D 3 And narrowed, resulting in the cable B can not be penetrated.
