Detailed Description

The present invention will be further illustrated by the following specific examples, which are carried out on the premise of the technical scheme of the present invention, and it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.

As shown in figure 1, the broadband cable assembly comprises a cable 2 and a connector arranged at the end of the cable 2, wherein the connector is connected with one end of the cable 2 and used for connecting the cable 2 to other equipment or cables, the connector comprises a shell 1 and a contact pin 3 arranged in the shell 1, the shell 1 is made of stainless steel, the contact pin 3 is made of high-elasticity beryllium copper, the contact pin 3 is connected with a conductor of the cable 2, and the head end of the contact pin 3 is in a needle point shape and is conveniently connected to a connector female head of other equipment. Casing 1 includes shell body 11 and

interior casing

12, 3 outsides of contact pin are equipped with insulating cover 4, insulating cover 4 adopts the high strength PEI material to be hollow circular cylinder, be equipped with the first spread groove 41 that corresponds with the outer circumference of insulating cover 4 on the interior casing 12, the outer wall middle part position of contact pin 3 is equipped with the second spread groove 42 that corresponds with the interior circumference of insulating cover 4, thereby insulating cover 4 card is in two spread grooves, contact pin 3 passes through insulating cover 4 to be fixed in interior casing 12, thereby air medium is passed through on contact pin 3's both sides and insulating, the centre supports through insulator 4 of thin slice medium, the cut-off frequency of cable subassembly has been promoted.
