Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

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 herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 3, a straight-end power line includes a first plug 1 and a second plug 2, the first plug 1 is connected to the second plug 2 through a wire harness 3, a first insertion groove 11 is disposed at an end of the first plug 1 away from the second plug 2, two power terminals 111 and a plurality of signal terminals 112 are disposed in the first insertion groove 11, a separation plate 113 is further disposed in the first insertion groove 11 and used for separating the power terminals 111 from the signal terminals 112, and heights of the two power terminals 111 protruding from an end surface of the first plug 1 are not equal. Specifically, in this example, the first plug 1 and the second plug 2 of the power cord are both straight-head-shaped, which is convenient for a user to hold and pull. The first plug 1 is provided with a first insertion groove 11, and the first insertion groove 11 is used for protecting the power terminals 111 and the signal terminals 112 located in the first insertion groove 11, so as to prevent the power terminals 111 and the signal terminals 112 from being bent by external force when the first plug 1 is not in use, and thus the first plug cannot be correctly inserted into a socket (not shown). Further, in this example, the signal terminals 112 are isolated from the power terminals 111 by the isolation board 113, so as to reduce electromagnetic interference of the power terminals 111 on the signal terminals 112 when the power terminals are energized. It should be noted that, the heights of the two power terminals 111 protruding the first plug 1 are not the same, when the user inserts the first plug 1 into the socket by hand, the longer power terminal 111 can be firstly clamped with the corresponding jack on the socket, so as to play a role in positioning, reduce the tightness when the power terminal 111 is inserted, avoid the two power terminals 111 from being inserted into the jacks simultaneously, facilitate the user to insert and remove, and have good practicability.

As shown in fig. 1 to 3, the second plug 2 is provided with a second insertion groove 21, a fixing portion 22 is provided around the second insertion groove 21, and the fixing portion 22 is provided with a bolt hole 221. In particular, the second plug 2 is also provided with a plug-in slot 21 for protecting the power terminals therein. It should be noted that, the fixing portion 22 is further disposed on the second inserting groove 21, and after the second inserting groove 21 is inserted into a corresponding socket, the bolt hole 221 of the fixing portion 22 is penetrated by a bolt, so that the second plug 2 and the socket can be stably connected without falling off.

As shown in fig. 4, the wire harness 3 includes an electric wire 31, a signal wire 32, an aluminum plastic film 33, a protective shell 34, and a harness shell 35, the electric wire 31 and the signal wire 32 are electrically connected to the power terminal 111 and the signal terminal 112, respectively, the electric wire 31 is disposed in the aluminum plastic film 33, the protective shell 34 is disposed outside the aluminum plastic film 33, and the signal wire 32 is disposed between the protective shell 34 and the harness shell 35.
