Abstract
The utility model discloses an anti-overvoltage and anti-lightning connector which solves the problem that when invading into coaxial cable core wires to spread to the connector, over-voltage and lightning-induced overvoltage can instantaneously produce spark discharge to the shell of the connector and quickly discharge to the earth, thus subsequent circuit board elements and devices are effectively prevented from being shocked and damaged. The connector comprises a through connector and a needle connector which are both arranged in a port or two ports, and one or a plurality of discharge points are additionally arranged. The utility model has the advantages that the over-voltage or lightning-induced pulse on lines can be directly short-circuited to discharge to the earth, and the anti-overvoltage and anti-lightning connector has better effect and stability, higher safety, very low cost and favorable application prospect, and can be widely used in communications, transportation, computers and other departments.
Description
Affiliated technical field
This utility model relates to a kind of connector, comprises connecting perforation head and the pin type connector that coaxial cable is used, and is the anti-overvoltage connector of anti-thunder and lightning.Be widely used in departments such as communication, traffic, computer.
Background technology
Known CATV amplifier or its connector of optical workstation, commonly used have the head of perforation and a pin type head, because of all there not being the anti-overvoltage effect of anti-thunder and lightning, every thunderstorm season, meet lightning induction or overvoltage, very easily burn out the components and parts on its circuit board, cause heavy economic losses, cause the rapid increase of a large amount of complaints of user and maintenance capacity.And the manufacturer that has is designed into lightning protection function on the circuit board, and its effect is not very good yet, can not show a candle to directly with its design on connector more directly, more effective.Because what thunder and lightning or overvoltage at first will be passed through is exactly connector; as long as thunder and lightning or overvoltage are in time released on connector; and connector directly is connected equipment metal shell and ground connection by screw thread; so give thunder and lightning and overvoltage provide one the most safe and reliable; also be direct and the most nearest leakage path, thereby protected the safety of subsequent conditioning circuit board component.
Summary of the invention
The purpose of this utility model will provide so a kind of anti-thunder and lightning to prevent the overvoltage connector just, and external form and size are identical with common connector, just increases single or multiple metal type discharge tip in the port, makes it have the function of the anti-overvoltage of anti-thunder and lightning.For finishing above-mentioned task, the solution that the utility model adopts is, the one, promptly connect head and pin type head to existing by two kinds of the coaxial cable transmission signals common device connectors, in an one port or two ports, increase the anti-overvoltage metal discharge tip of single or multiple anti-thunders and lightnings, comprise pin type discharge tip or zigzag discharge tip.
Specific as follows: as, to increase discharge tip at an one port or two ports to connecting head.Discharge tip can be the pin type, also can be zigzag, and quantity is single or a plurality of.Discharge tip does not contact with the coaxial cable core wire that penetrates the perforation head.
To pin type head, increase discharge tip at an one port or two ports.Discharge tip can be the pin type, also can be zigzag, and quantity is single or a plurality of.Discharge tip does not contact with contact pin, does not contact with the coaxial cable core wire that inserts pin type head contact pin yet.
Action principle is such: when overvoltage and lightning induction high voltage intrusion coaxial cable core wire; when preventing the overvoltage connector through anti-thunder and lightning; because point discharge; can be at first by discharge tip to the housing sparkover; and introduce the earth by earth connection and discharge, effectively do not protected components and parts on the circuit board of back breakdown even burn.
The beneficial effects of the utility model: compared with prior art; the anti-overvoltage connector of the anti-thunder and lightning of the utility model; the overvoltage of invading on the coaxial cable core wire and lightning induction pulse can be sparked and be shorted to ground, effectively protect the circuit of back, be a simple and effective lightning protection new unit.Because of its simplicity of design, easy for installation, increase any cost hardly, practicality is very big.
