Abstract
The utility model discloses a two fixed strain clamp of formula of cup jointing. The technical scheme who adopts includes the fastener body and fixes the drainage plate on the fastener body, drainage plate one end installation drainage tube, its characterized in that: the drainage plate rear end extend and to have sleeve portion, has seted up screw, lower extreme in sleeve portion upper end and be equipped with the screw socket, the drainage tube front end extend have with the cover head that sleeve portion suited, it has screw section, lower part to be equipped with the nut to extend in set head upper end. The utility model discloses a two fixed strain clamp of formula of cup jointing, during the installation, earlier insert the sleeve portion of drainage plate rear end with the cover head of drainage tube upper end in, the screw section of its front end stretches out the screw, rethread tighten nut is fixed, at this moment, the aluminum plate contact surface between the drainage section is very inseparable, further tightens fixedly afterwards through the nut of the other end, realizes two fixedly.
Description
Technical field
The utility model relates to a kind of power circuit auxiliary equipment, is specifically related to a kind of strain clamp.
Background technology
Existing strain clamp comprises wire clip body and drainage plate, and described wire clip body is connected with wire, and described drainage plate is fixedly mounted on wire clip body rear portion.The structure (if the patent No. is for shown in the Chinese invention patent of 200410096022.9) of described drainage plate comprises upper Drainage Section, lower Drainage Section, rear end, described upper Drainage Section arranges a jaws, upper end, described lower Drainage Section arranges flat part, the flat part of lower Drainage Section is inserted in the jaws of Drainage Section, fixed by nut.The drainage plate shortcoming of this structure is: 1, install very difficult, operating personnel needs after in the jaws that the flat part of lower Drainage Section is inserted Drainage Section in the air by height accurately, also need with hand, lower Drainage Section to be buttressed, with another hand, nut screwing clamping is fixed again, we know, aerial at height, and operating personnel inherently stands just unstable, very difficult as this operation, nor safety; 2, under the effect of natural climate environment and load current, the aluminium sheet touch panel between upper Drainage Section, lower Drainage Section easily loosens, oxidation, thus causes the contact-making surface resistance of drainage plate to become large, and drainage plate generates heat.
For the problems referred to above, the patent No. is the Chinese utility model patent of " 200920198891.0 ", disclose one " drainage rod type strain clamp ", it adopt socket mode to connect between Drainage Section, lower Drainage Section, aluminium sheet contact-making surface between Drainage Section is isolated from the outside not easily intake, thus solves the problem of oxidation.But the shortcoming also existed is: 1, only connected by coupling single-point between upper Drainage Section, lower Drainage Section, its bonding strength is inadequate; 2, not easily judge whether be in place between upper Drainage Section, lower Drainage Section; 3, joiner structure relative complex, installs difficulty.
Utility model content
The technical problems to be solved in the utility model is to provide the two fixing strain clamp of a kind of socket joint type.
For solving the problem, the technical solution adopted in the utility model comprises wire clip body and is fixed on the drainage plate on wire clip body, drainage tube is installed in described drainage plate one end, it is characterized in that: described drainage plate rear end is extended with sleeve part, offer screw in sleeve part upper end, lower end is provided with screw socket, described drainage tube front end is extended with the cover head adapted with described sleeve part, and at cover, head upper end is extended with threaded shank, bottom is provided with nut.
The two fixing strain clamp of described socket joint type, is characterized in that: the screw of described sleeve part is provided with waterproof washer.
The two fixing strain clamp of described socket joint type, is characterized in that: described sleeve part inner chamber conically.
The two fixing strain clamp of socket joint type of the present utility model, during installation, first the cover head of drainage tube upper end is inserted in the sleeve part of drainage plate rear end, the threaded shank of its front end stretches out screw, fixed by nut screwing clamping, now, the aluminium sheet contact-making surface between Drainage Section closely again, finally tighten fixing further by the nut of the other end again, realize two fixing.By the strain clamp of this connected mode reality, except solving the problem of the aluminium sheet contact-making surface water inlet oxidation between Drainage Section, its degree of being connected firmly is far above traditional drainage rod type strain clamp.In addition, installation is more prone to.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the cutaway view of the two fixing strain clamp of the utility model socket joint type.
Embodiment
As shown in Figure 1, the two fixing strain clamp of socket joint type of the present utility model, comprise wire clip body 1 and be fixed on the drainage plate 2 on wire clip body 1, described drainage plate 2 rear end is extended with sleeve part 4, offer screw 5 in sleeve part 4 upper end, lower end is provided with screw socket 6, described drainage tube 3 front end is extended with the cover head 7 adapted with described sleeve part 4, and be extended with threaded shank 8 in cover head 7 upper end, bottom is set with nut 9, described nut 9 lower inner wall arranges step 11.
For optimizing such scheme further, the screw 5 of described sleeve part 4 is provided with waterproof washer 10, and anti-sealing enters its inside from screw, and the port of described sleeve part 4 also arranges waterproof washer as required, plays further waterproof, anti-oxidation effect.Described sleeve part 4 inner chamber conically structure, the sleeve part 4 of described drainage tube 3 front end also arranges the conical structure adapted with it, the connecting portion of conical structure, has to install easily, connect advantage closely.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection range of the present utility model.
