Embodiment Construction

[0023] Such as figure 1 As shown, the plug-in structure of the surge protector includes a base 1 and a protection module 3 , and the protection module 3 is plugged and connected to the base 1 so that the electrode pins of the protection module 3 are electrically connected to the terminals in the base 1 . A linkage rod 2 is provided on the protection module 3 , and the protection module 3 can be ejected from the base 1 by rotating the linkage rod 2 .

[0024] Such as figure 2 , image 3 As shown, the linkage rod 2 includes a handle portion 21, a rotating shaft portion 22 and a reverse thrust portion 23, wherein the handle portion 21 is in the shape of a thin plate, the axis of the rotating shaft portion 22 extends horizontally perpendicular to the plane of the handle portion 21, and the reverse thrust portion 23 extends substantially horizontally in the radial direction of the shaft portion 22 . The handle part 21 is provided with a card slot 24 opening downward.

Abstract

A pull and plug structure for a surge protector comprises a protecting module (3) and a base (1). The protecting module is in pull and plug connection with the base and rotatably connected with a linkage rod (2). The said linkage rod is composed of an inverse pushing part (23), a rotating shaft part (22) and a handle part (21), wherein the said inverse pushing part is contacted with the base; the said rotating shaft part is contacted with bottom of the protecting module; and the said handle part extends to top of the protecting module. When there is a need to remove the protecting module from the base, the protecting module can be pried out of the base based on lever principle by slight pulling of the linkage rod. The surge protector is convenient and saves force.

Description

technical field [0001] The invention relates to a surge protector, in particular to a plug-in structure of a surge protector. Background technique [0002] Surge protector (SPD) is an indispensable device in the lightning protection of electronic equipment. It can limit the instantaneous overvoltage that enters the power line and signal transmission line within the voltage range that the equipment or system can withstand, or the powerful overvoltage The lightning current leaks to the ground, protecting the equipment or system from being damaged by the impact. [0003] The surge protector generally includes a base and a protection module, and the protection module is plugged and connected to the base. When the protection module fails, only the protection module can be replaced. [0004] Chinese invention patent 03150798.0 discloses a "surge protector pluggable module and base", which allows one or more pluggable modules to be installed on a base by rationally designing the s...
