Background

With the rapid development of information technology, electronic information equipment and computer systems are widely used in various industries, and the equipment is extremely vulnerable to lightning and electric pulses due to low working voltage and impact voltage resistance and weak anti-interference capability. A surge protector, also called a lightning protector, is an electronic device for providing safety protection for various electronic equipment, instruments and meters and communication lines. When the peak current or the voltage is suddenly generated in the electric loop or the communication line due to the external interference, the surge protector can conduct and shunt in a very short time, so that the damage of the surge to other equipment in the loop is avoided.

The SPD backup protector is characterized in that when the SPD is conducted and has a fuse-through short circuit due to abnormal transient overvoltage of a power supply, the power supply can be tripped and powered off if the power supply is light, and a serious fire accident can be caused if the power supply is heavy, and the circuit can be rapidly disconnected if the SPD is short-circuited if the external disconnector is installed; when the SPD has lightning current, the external disconnector cannot be tripped by mistake, so that the lightning protection of the electrical equipment is always in an effective state.

The existing backup protectors also have the following disadvantages in use.

Because its adoption discharge tube of current backup protector reaches the effect of the lightning impulse current of releasing usually, however current discharge tube adopts one end to connect binding post usually, and the other end is connected to the coil in the backup protector, and this kind of connected mode makes discharge tube when releasing, because the interference of coil internal resistance for the lightning impulse current of releasing receives the restriction, thereby influences this backup protector's application range. Therefore, it is necessary to provide a backup protector that does not pass through the contacts.

The problem to current backup protector discharge capacity is little, the utility model provides a backup protector is through on will discharging the tube connection to first extension board and second extension board, wherein first extension board and second extension board are arranged first binding post and second binding post in respectively for should discharge the tube lug connection in this backup protector's input and output, avoided the interference of internal resistance, thereby reach stronger effect of the lightning impulse current of discharging, strengthened this backup protector's application range and security performance.

In order to solve the above problems, the utility model adopts the following technical proposal.

The utility model provides a backup protector, includes the drain pan and the upper cover of assembling with the drain pan, the drain pan both sides are equipped with first binding post and second binding post, be equipped with first extension board and second extension board in first binding post and the second binding post respectively, be equipped with in the drain pan and put discharge tube, this discharge tube links to each other with first extension board and second extension board.

Preferably, a cavity for accommodating the discharge tube is arranged in the bottom shell, and a first clamping groove and a second clamping groove which play a role in clamping are formed between the cavity and the shell.

Preferably, one end of the first extension plate is clamped to the first connection terminal, and the other end of the first extension plate is clamped to the first clamping groove.

Preferably, one end of the second extending plate is clamped to the second terminal, and the other end of the second extending plate is clamped to the second clamping groove.

Preferably, the discharge tube is fixed to the first extension plate and the second extension plate by welding.

Advantageous effects

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses be equipped with in the well drain pan and hold the chamber, should hold the intracavity and be equipped with discharge tube, will discharge on tube is connected to first extension board and second extension board, just first extension board and second extension board are arranged in first binding post and second binding post respectively for should discharge tube direct connect in the input and the output of this backup protector, avoided the interference of internal resistance, thereby reach stronger effect of the lightning impulse current of releasing, strengthened the application range and the security performance of this backup protector.
