The anti-loosening protection apparatus comprises a pedestal (10) and a plugging module (20); and the plugging module (20) is inserted into a middle recessed hole of the pedestal (10). Besides, the anti-loosening protection apparatus is provided with a locking mechanism (30) including an inclined-surface plug (31), a locking spring (32), and a fixed screw (33); a cylinder (11) is arranged at the outer wall of the pedestal (10); a locking opening (21) is arranged at the outer wall of the plugging module (20), wherein the cylinder (11) corresponds to the locking opening (21); and the inclined-surface plug (31), the locking spring (32), and the fixed screw (33) are successively connected and are arranged in the cylinder (11) of the pedestal (10). According to the scheme, the provided anti-loosening protection apparatus has advantages of simple structure, low cost, and high practicability and reliability and is suitable for effective and normal working of the surge protection device (SPD) in a vibration environment.
Description
Technical field
The utility model relates to the protective device of Surge Protector, relates in particular to a kind of locking protective device of Surge Protector plug-in module.
Background technology
As Fig. 1, Surge Protector (Surge protection Device is called for short SPD) is mainly to rely on the frictional force between module 20 and base 10 to guarantee that it is connected; In transportation with having under the environment of vibration and use easily and lost efficacy.Especially along the railway vibration cannot be avoided, for guaranteeing that it effectively uses, other safeguard measure can only be increased.
Utility model content
The purpose of this utility model is just to overcome prior art existent defect and deficiency, and a kind of locking protective device of Surge Protector plug-in module is provided.
The purpose of this utility model is achieved in that
The utility model comprises base and plug-in module, in the middle shrinkage pool of plug-in module inserted base;
Be provided with retaining mechanism, retaining mechanism comprises inclined-plane plug, locking spring and hold-down screw;
Outer wall at base is provided with cylinder, at the outer wall of plug-in module, is provided with fore shaft, cylinder and fore shaft position correspondence;
Inclined-plane plug, locking spring and hold-down screw are connected successively, are placed in the cylinder of base.
Working mechanism of the present utility model:
When the plug-in module of SPD inserts to base, the front end inclined-plane that plug-in module acts on retaining mechanism makes inclined-plane plug indentation base, when reaching the fore shaft of plug-in module, under the effect of locking spring, retaining mechanism buckles into module, realizes the effect of plug-in module locking.When plug-in module will be extracted, first plug-in module is extracted from its rear end, made retaining mechanism depart from plug-in module, then plug-in module is extracted.
The utlity model has following advantages and good effect:
1. simple in structure, with low cost, practical and reliable;
2. be applicable to SPD under vibration environment effectively, normally work.

3. hold-down screw 33
The internal thread adaptation of the cylinder 11 of the external screw thread of the afterbody of hold-down screw 33 and base 10; Be convenient to fixing and locking mechanism 30.
Two, the using method of locking protective device
1. retaining mechanism 30 is placed in to the cylinder 11 of base 10, with straight screwdriver or similarly instrument hold-down screw 33 is tightened;
2. by the interstitial hole of plug-in module 20 inserted bases 10, because the inclined-plane plug 31 of retaining mechanism 30 is locked under the tension force effect of locking spring 32, prevent becoming flexible between plug-in module 20 and base 10;
When 3. wish is extracted base 10 by plug-in module 20, need retaining mechanism 30 be extracted from rear end with straight screwdriver or similar instrument.
Three, result of the test
1, vibration test: meet GB/T 2423.10-1995.
Claims (2)
