Detailed Description

In order to make the technical field person understand the scheme of the present invention better, the following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical scheme in the embodiments of the present invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The terms "first," "second," and the like in the description and claims of the present invention and in the above-described drawings are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

As shown in fig. 1 and 2, an MPP power pipe connector includes a connection sleeve 1, two ends of which can be sleeved with an MPP power pipe, a limiting convex ring 2 is integrally formed in the middle of the inner wall of the connection sleeve 1, the inner diameter of the connection sleeve 1 is equal to the outer diameter of the MPP power pipe, at least two arc-shaped pressing plates 3 for pressing the MPP power pipe from the inner side are respectively disposed on two sides of the limiting convex ring 2, and a control mechanism for controlling the arc-shaped pressing plates 3 to loosen or press the MPP power pipe is correspondingly disposed on the connection sleeve 1.

In this embodiment, as shown in fig. 3, the control mechanism includes a threaded column 5 and a nut 7, a sliding portion 31 is integrally formed at one end of the arc-shaped pressing plate 3 close to the limit protruding ring 2, a sliding groove 4 which is matched with the sliding portion 31 to slide is arranged on a side wall of the limit protruding ring 2 along a radial direction, the threaded column 5 is arranged in the sliding groove 4, and a lower end of the threaded column 5 is connected to the sliding portion 31. The upper end of the threaded column 5 penetrates through the connecting sleeve 1 and is in threaded connection with the nut 7. Because arc clamp plate 3 passes through 4 cooperation sliding connection of spout on the lateral wall of sliding part 31 and spacing bulge loop 2, improves the stability that arc clamp plate 3 removed, avoids it to take place the skew, and because the setting of screw post 5 is in spout 4, makes it not influence cup jointing of adapter sleeve 1 and MPP power tube.
