DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0021] like Figures 1 to 4As shown, the railway signal relay contact assembly includes a plurality of groups of jacks 102 arranged on a relay fixing seat 101, and also includes a plurality of groups of mounting covers 2 installed at the front end of the relay fixing seat 101, each mounting cover 2 is respectively located at the front side of each jack 102, and a shielding protection assembly for shielding and protecting the jack 102 is arranged on the mounting cover 2;

[0022] When the contact assembly on the railway signal relay is in operation, the two sets of shielding and protective plates 302 in the resisting state are blocked on the front side of the socket 102 by the squeezing and pushing action of the extrusion assembly on the two sets of mounting plates 301 inside the mounting cover 2 and the opposing pushing action of the two sets of telescopic assemblies on the two sets of shielding and protective plates 302, so as to reduce the probability of dust accumulation and moisture inside the socket 102, and facilitate the stable connection and use of the subsequent railway signal relay contact assembly.

[0023] The shielding and protection assembly includes two groups of mounting plates 301 arranged inside the mounting cover 2, and an extrusion assembly for pushing and extruding the mounting plates 301 is arranged on the mounting cover 2. The opposite sides of the two groups of mounting plates 301 are connected with shielding and protection plates 302 through telescopic assemblies. The two groups of shielding and protection plates 302 are located in front of the socket 102, and the two groups of shielding and protection plates 302 are pushed by the telescopic assembly to shield and protect the socket 102; the front side of the socket 102 is shielded and blocked by the shielding and protection plates 302, so as to reduce the probability of dust accumulation and moisture inside the socket 102.

[0024] The two sets of shielding and protective plates 302 are provided with an inclined surface 303 on one side close to the outside of the mounting cover 2; the inclined surface 303 is convenient for abutting against the front end of the plug to drive the two sets of shielding and protective plates 302 to move.

[0025] The telescopic assembly includes a plurality of first sleeves 401 fixed on the mounting plate 301, each of which is slidably connected with a first slide bar 402, one end of the first slide bar 402 is fixed to the shielding protection plate 302, and a first spring 403 is sleeved on the outer side of each first sleeve 401, and the two ends of the first spring 403 are respectively set to resist the mounting plate 301 and the shielding protection plate 302; the telescopic movement of the shielding protection plate 302 is guided by the plurality of first sleeves 401 and the first slide bar 402, and the shielding protection plate 302 is squeezed and reset after the movement by each first spring 403.

[0026] The extrusion assembly includes a fixed plate 501 fixed on one side of the mounting plate 301, a second spring 502 for extruding and pushing the fixed plate 501 is connected between the fixed plate 501 and the inside of the mounting cover 2, and a guide assembly for guiding during the extrusion process is arranged between the fixed plate 501 and the mounting cover 2; the mounting plate 301 is extruded and pushed by the fixed plate 501 and the second spring 502, and during the extrusion and pushing process, the shielding protection assembly is abutted against the front side of the socket 102 through the connection action of the various components on the telescopic assembly.

[0027] The guide assembly includes a second sleeve 601 fixed on the fixed plate 501, and a second slide bar 602 is slidably connected to the second sleeve 601. One end of the second slide bar 602 is fixed to the inner wall of the mounting cover 2, and the second spring 502 is sleeved on the outer side of the second sleeve 601; through multiple groups of second sleeves 601 and second slide bars 602, the extrusion and push of the fixed plate 501 and the mounting plate 301 are guided.

[0028] When the contact assembly on the railway signal relay is in operation, the two sets of shielding and protective plates 302 in the resisting state are blocked and blocked on the front side of the jack 102 by the squeezing and pushing action of the squeezing assembly on the two sets of mounting plates 301 inside the mounting cover 2 and the resisting and pushing action of the two sets of shielding and protective plates 302 by the two sets of telescopic assemblies, thereby reducing the probability of dust accumulation and moisture inside the jack 102, and facilitating the stable connection and use of the subsequent railway signal relay contact assembly;

[0029] When the socket 102 on the contact assembly needs to be connected to an external plug, the end of the plug is pushed toward the inside of the mounting cover 2 and connected to the socket 102. In the process of pushing and squeezing the plug, the end of the plug abuts against the inclined surfaces 303 on the two sets of shielding protective plates 302, pushing the two sets of shielding protective plates 302 to move away from each other. After the plug is plugged and connected to the socket 102, the elastic squeezing effect of the first springs 403 on the telescopic assembly causes the front ends of the two sets of shielding protective plates 302 to abut against the outside of the inserted plug, squeezing the inserted plug, thereby preventing the plug from falling off after connection.
