Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-7, the utility model provides a protective cover for a wiping line connector, which comprises two pairs of covers, the existing protective cover is basically a pair of covers, and the pair of covers is also formed by buckling two covers 1, the structure is simple, the length of the protective cover is fixed, and can not be adjusted according to the length of the connector, each pair of covers is formed by fixedly connecting two covers 1, the two covers 1 can be connected by buckling or screwing, because the buckling connection is simple and convenient, and the screw is not needed, the application is more, a limit plate 5 is arranged in the middle of the cover 1, the lower end of the limit plate 5 is provided with a mounting groove 4, the mounting groove 4 and the limit plate 5 are used for clamping and sleeving the protective cover on the connector, one end of the covers is open, the two pairs of covers are connected by a telescopic rod 2 and move along the length direction of the covers to be close, in order not to affect the installation of the connector, the telescopic rod 2 is positioned above the limiting plate 5, and the telescopic rod 2 can be designed into two parts (as shown in fig. 6 and 7), so that the two pairs of the covers can move stably, and two ends of the telescopic rod 2 extend into the covers through the openings and are fixedly connected with the covers; install the locking button 3 that can restrict the telescopic link 2 and stretch out and draw back on the outer wall of housing 1, the structure of locking button 3 is as shown in fig. 8 and fig. 9, locking button 3 includes box body 31 of fixed mounting on the outer wall of housing 1 and slides the slider 32 of pegging graft in box body 31, set up the perforation 33 that supplies telescopic link 2 to pass on box body 31 and the slider 32, it has slipmat 34 to paste on the perforation 33 pore wall on the slider 32, slider 32 is tight on telescopic link 2 through the top of a tight spring 35 top, when pressing down slider 32, slipmat 34 and the separation of telescopic link 2, telescopic link 2 can freely stretch out and draw back this moment, when loosening the pressing to slider 32, slider 32 compresses tightly on telescopic link 2 under the effect of top tight spring 35, thereby with the tight messenger's of telescopic link 2 unable free expansion and draw back.

When the protective cover for the sliding contact line connector is used, two pairs of cover bodies are pulled according to the length of the connector to expand the length of the protective cover until the lengths of the protective cover and the connector are approximately equal (when the cover bodies are pulled, a locking button 3 needs to be pressed down firstly, then a telescopic rod 2 is stretched, the locking button 3 is loosened after the telescopic rod 2 is stretched to a proper position), then the cover shells 1 of the two pairs of cover bodies are disassembled, a mounting groove 4 is clamped on the connector, then the position of the connector in the mounting groove 4 is adjusted, the length direction of the connector is aligned with the length direction of the mounting groove 4, finally the cover shells 1 are fastened together, if the connector still shakes in the cover bodies after the cover shells 1 are fastened, the locking button 3 can be pressed down again to finely adjust the length of the telescopic rod 2 until the connector cannot shake in the cover shells 1 along the length direction of the connector (because the widths of the connectors of the same model and different lengths, therefore, the connector can only slide along the length direction of the connector in the installation groove 4 after the connector is installed in the installation groove 4, so that the problem can be solved by adjusting the expansion amount of the expansion link 2).

As an optional implementation mode, the upper surface of one housing 1 in the pair of housing bodies is provided with a clamping groove 9, the upper surface of the other housing 1 is fixedly provided with a clamping plate 8, and the clamping plate 8 is clamped in the clamping groove 9.

An ash blocking tape 6 is fixedly arranged in one pair of the cover bodies, and a tape 7 pulled out of the ash blocking tape 6 moves along the length direction of the telescopic rod 2 and extends into the other pair of the cover bodies and is fixedly connected with the cover bodies; the upper surface level of chi area 7 and hug closely the lower surface of limiting plate 5, the design like this, after the protector is stretched and tightly overlaps on the connector, accessible keeps off grey tape measure 6 and blocks that external dust gets into in mounting groove 4 influence the connector and normally work, because two pairs of covers quilt are stretched the back, regional direct and external intercommunication between the two pairs of covers, at this moment, external dust falls on the connector easily and influences the connector and normally work, consequently specially blocks on the connector through keeping off grey tape measure 6 that external dust falls, the structure that keeps off grey tape measure 6 is the same with the structure of current tape measure, can regain the book automatically after chi area 7 draws to stretch out.

The width of chi area 7 is not less than the width of the cover body, design like this, further promoted the separation performance of protection casing to the dust, ensure on the dust can not fall the connector, the both sides of the chi area 7 of design like this can stretch out and slide on the outer wall of housing 1 from the housing 1 outer wall, at this moment, the gliding gap of confession chi area 7 of design on the housing 1 should not be too wide, it is suitable with the inseparable slip of housing 1 to use chi area 7, on order to avoid external dust to fall on the connector from gap department entering mounting groove 4.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
