Description
Technical Field
The present invention relates to an electrical connection terminal and an electrical connection device, and more particularly, to an electrical connection terminal and an electrical connection device for grounding.
Background
The current wiring harness grounding method comprises the following steps: carry out the crimping with the annular terminal that has octagonal hole with the electric wire earlier, then manually with this annular terminal cover that has octagonal hole on the octagonal protruding position of double-screw bolt, wherein the double-screw bolt is welded on the automobile body and ground connection through resistance welding, compress tightly between ground connection double-screw bolt and nut with the annular terminal that has octagonal hole with the nut at last to realize pencil ground connection and fixed.
However, such a wire harness grounding method adopted at present has the following problems:
(1) when more than two ring terminals are required to be sleeved on the same ground stud, a worker needs to pay more attention to manually arrange the ring terminals at a specific angle, such as 90 degrees, 120 degrees and the like, to avoid other components in the vehicle. When the number of the ring terminals increases, a worker easily makes a mistake.
(2) Since the ring terminal is manually fitted over the ground stud by a worker, the ring terminal is easily warped, so that interference between a plurality of warped ring terminals occurs when the nut is finally screwed, thereby causing false screwing and poor contact.
(3) Because the ground studs have height limitation, and a plurality of annular terminals are superposed on the same stud to easily cause warping, the number of annular terminals arranged on one ground stud is very limited. Generally, 2 are selected to ensure the grounding effect.
(4) The ground stud and nut, as well as the ring terminal, are metal pieces whose edges tend to pinch and cut the surrounding wires, causing the insulation of the surrounding wires to fail, thereby resulting in a tendency for short circuits to occur.

Detailed Description
While the invention will be described in further detail in connection with specific embodiments and with reference to the accompanying drawings, the following description sets forth numerous details for a thorough understanding of the invention, it will be readily apparent that the invention may be embodied in many other forms other than those described herein, and it will be readily apparent to those skilled in the art that the invention may be practiced with many modifications and alterations without departing from the spirit of the invention, and the scope of the invention should not be limited by the contents of this detailed embodiment.
This application uses specific words to describe embodiments of the application. Reference to "one embodiment," "another embodiment," and/or "some embodiments" means that a particular feature, structure, or characteristic described in connection with at least one embodiment of the application. Therefore, it is emphasized and should be appreciated that two or more references to "one embodiment" or "another embodiment" or "an alternative embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, some features, structures, or characteristics of one or more embodiments of the present application may be combined as appropriate.
It should be noted that in the foregoing description of embodiments of the present application, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure aiding in the understanding of one or more of the embodiments. This method of disclosure, however, is not intended to require more features than are expressly recited in the claims. Indeed, the embodiments may be characterized as having less than all of the features of a single embodiment disclosed above.

As shown in fig. 1, the male type electric connection terminal 100 may include a plug portion 120, a first connection portion 140, a second connection portion 160, and a fixing portion 180.
Referring to fig. 1, the plug portion 120 may have a comb shape, and have a ridge portion 122 and a plurality of bar-shaped electric connection terminals 124. In fig. 1, the strip-shaped electric connection terminals 124 are shown to have four, which are arranged on the same plane and extend from the ridge portion 122 in parallel with each other. In some embodiments, the number of the strip-shaped electrical connection terminals 124 may be selected according to the actual application, for example, adjusted to one, two, three, five, ten or any other number. In other embodiments, the plurality of strip-shaped electrical connection terminals 124 may also be arranged on a plurality of different planes.
