目前的有线电视系统或宽频网络系统都是利用同轴线缆来作为传输讯号的载体，其中在构成有线电视系统或宽频网络系统时，同轴缆线的串联，一对多的线路需求，都要利用各种不同的讯号连接器来完成讯号的传递或分路，例如双头连接器或讯号分配器；如图1、图2所示，图中所示的为讯号连接器的一种，其依序是由外壳41、防水套42及讯号端子43所组成，外壳41是金属材质制成一中空贯穿的圆柱体，一端为连接端411，其上具有一开口4111，一端则为组合端412，其上也具有一开口4121，而在外壳41的外缘成形有螺纹，以供同轴缆线的接头螺接啮合，防水套42是由橡胶等挠性材质制成一中空贯穿的圆柱体其外径约略等于外壳41的内径，恰可塞入于外壳41内，防水套42对应连接端411的开口4111处设有一恰等于开口4111的突出部421，突出部421伸出于外壳41的连接端411，并完全使开口4111密封，使水气无法由开口4111的接缝处渗入于外壳41内，达到防水的效果，当然在突出部421的顶端具有一开口4211，以供同轴缆线插入作电性连接；讯号端子43为金属材质所制成，一端为输入端431，用以供同轴缆线讯号连接，另一端为连接端432，用以与电路板电性连接，其中讯号端子43中央处包覆有一以绝缘材质制成的绝缘套433，绝缘套433的外径约略等于防水套42的内径，讯号端子43以输入端431插入防水套42内，再由绝缘套433迫紧于防水套42而固定于外壳41内，其中讯号端子43的输入端431恰对正于突出部421的开口4211，以供同轴缆线插入与它电性连接，连接端432则可利用导线或直接的连接于电路板上与它电性连接。The current cable TV system or broadband network system all use coaxial cables as the carrier for transmitting signals. When forming a cable TV system or broadband network system, the series connection of coaxial cables and the one-to-many line requirements are all necessary. It is necessary to use various signal connectors to complete signal transmission or branching, such as double-headed connectors or signal distributors; as shown in Figure 1 and Figure 2, the one shown in the figure is a kind of signal connector, It is composed of a casing 41, a waterproof cover 42 and a signal terminal 43 in sequence. The casing 41 is a hollow cylindrical body made of metal material. One end is a connecting end 411 with an opening 4111 on it, and the other end is a combined end. 412, which also has an opening 4121, and a screw thread is formed on the outer edge of the shell 41 for the joint screw engagement of the coaxial cable. The waterproof cover 42 is made of a flexible material such as rubber and is a hollow penetrating cylinder. The outer diameter of the body is approximately equal to the inner diameter of the casing 41, and it can be inserted into the casing 41. The waterproof cover 42 is provided with a protrusion 421 that is exactly equal to the opening 4111 at the opening 4111 of the connection end 411.

在实际生产一讯号连接器的过程是：The process of actually producing a signal connector is:

1．将一金属板材冲制成讯号端子；1. Punching a sheet metal into a signal terminal;

2．将讯号端子装设一绝缘套上；2. Install the signal terminal on an insulating sleeve;

3．于绝缘套上装设防水套；3. Install a waterproof cover on the insulating cover;

4．将讯号端子、绝缘套、防水套一并的冲压于外壳内。4. Stamp the signal terminals, insulating sleeves, and waterproof sleeves into the housing together.

然而由上述的结构及生产的过程不难发现，防水套为达到防水的目的是为具挠性的材质制成，具有大小约略等于外壳的内径，而讯号端子配合同轴缆线轴心的大小，其尺寸小于防水套的内径，因此防水套与讯号端子的输出端间具有一间隔，在将端子、绝缘套、防水套一并的冲压于外壳内时，由于外壳的内径与防水套的外径约略相同，而绝缘套是利用紧配合的关系将讯号端子固定于外壳内，因此在冲压时必须施以一定的力量，且对应的关系必须相当的精确，但由于防水套具有挠性，因此对应关系稍有误差，将使防水套弯曲，而无法正确的进入到外壳内，甚至由于防水套的弯曲，而压制到讯号端子的输入端使其弯折，将使输入端无法对正于突出部的开口，即无法供同轴缆线的轴心插入作电性连接，造成不合格品的产生。However, it is not difficult to find from the above-mentioned structure and production process that the waterproof cover is made of flexible material for the purpose of waterproofing, with a size approximately equal to the inner diameter of the shell, and the signal terminal matches the size of the coaxial cable axis , whose size is smaller than the inner diameter of the waterproof case, so there is a gap between the waterproof case and the output end of the signal terminal. The diameters are roughly the same, and the insulating sleeve uses a tight fit to fix the signal terminal in the housing, so a certain force must be applied when stamping, and the corresponding relationship must be quite accurate, but because the waterproof sleeve is flexible, so A slight error in the corresponding relationship will cause the waterproof cover to bend and cannot enter the housing correctly. Even due to the bending of the waterproof cover, the input end of the signal terminal will be pressed to make it bend, which will make the input end unable to align with the protrusion. The opening of the part, that is, the axial center of the coaxial cable cannot be inserted for electrical connection, resulting in the generation of substandard products.
