In the description of the present specification, the terms "upper", "lower", and the like indicate orientations or positional relationships based on those shown in the drawings, only for convenience of describing the present application and simplifying the description, but do not indicate or imply that the referred devices or units must have a specific direction, be configured in a specific orientation, and operate, and thus, should not be construed as limiting the present application.
Fig. 1-3 illustrate one embodiment of such a power connector of the present application for directing power provided by an upstream power source to a downstream powered device. The power connector also includes a male plug 1 with a positive plug 101 and a negative plug 102 and a female plug 2 with a positive socket 201 and a negative socket 202, as in the conventional power connector. In practical application, the female plug 2 is connected with an upstream power supply device, the male plug 1 is connected with a downstream power utilization device, after the male plug 1 and the female plug 2 are plugged into each other, the positive plug 101 is just inserted into the positive jack 201, and the negative plug 102 is just inserted into the negative jack 202, so that electric energy provided by the upstream power supply device is led to the downstream power utilization device through the power connector.
The key improvement of this embodiment is that the male plug 1 is provided with an inward-recessed insertion groove 101, and the positive plug 101 and the negative plug 102 are both accommodated in the insertion groove 103. The female plug 2 includes a plug column 203 matching with the shape of the plug groove 103, and the positive electrode jack 201 and the negative electrode jack 202 are both disposed in the plug column 203. And, the aforesaid peg 203 is fixed to be set up waterproof sealing ring 3 outward, and this waterproof sealing ring 3 is the O type circle of rubber material, and after peg 203 inserted the inserting groove 103, aforesaid waterproof sealing ring 3 is pressed from both sides between peg 203 surface and inserting groove 103 wall to plug up the gap of peg and inserting groove fitting surface, prevent that the water in the environment from flowing to above-mentioned positive, negative pole bolt or positive, negative jack from the gap.
It is understood that, if the above-mentioned structure of the insertion groove 103 and the insertion column 203 is not provided on the male and female plugs, the male and female plugs are guided and fixed only by the positive and negative plugs and the positive and negative jacks which are matched with each other, the positive and negative plugs are easily bent or inclined to deform, and the problem of small connection force of the male and female plugs also exists. In this embodiment, the mating grooves 103 and the mating posts 203 have a guiding effect on the mating of the male and female plugs, thereby greatly facilitating the mating of the male and female plugs, reducing the possibility of deformation of the positive and negative plugs, and greatly improving the connection force of the male and female plugs after mating to prevent the male and female plugs from being separated from each other in the use process. In addition, the positive and negative plugs are accommodated in the insertion groove 103, and have a structural protection function, so that the positive and negative plugs are prevented from being exposed outside directly and being damaged easily.
In order to facilitate the assembly and fixation of the waterproof sealing ring 3 on the plugging column 203, a ring of annular caulking groove 204 is formed around the surface of the plugging column 203, and the waterproof sealing ring 3 is embedded in the annular caulking groove 204.
Further, the positive electrode insertion hole 201 and the negative electrode insertion hole 202 are linear holes arranged in parallel, and the positive electrode insertion hole 201 and the negative electrode insertion hole 202 are both arranged perpendicular to the annular caulking groove 204, that is, the positive electrode insertion hole and the negative electrode insertion hole are both arranged perpendicular to a plane surrounded by the annular caulking groove.
In this embodiment, the positive plug 101 and the negative plug 102 are linear pins arranged in parallel, and the lengths of the positive plug 101 and the negative plug 102 extend along the depth direction of the insertion groove 103. Thus, when the plug column 203 and the plug groove 103 are plugged together along the groove depth direction of the plug groove, the positive and negative plugs are just inserted into the positive and negative jacks along the same direction.
Defining that the left direction parallel to the paper surface is "left" and the right direction parallel to the paper surface is "right" in fig. 2, the positive plug pin 101 and the negative plug pin 102 are arranged in the insertion groove 103 at a distance from left to right, and we can divide the insertion groove 103 into left and right half-parts, namely a left half-groove for accommodating the positive plug pin 101 and a right half-groove for accommodating the negative plug pin 102, and the left half-groove and the right half-groove are directly communicated.
The left half groove and the right half groove have asymmetric cross section shapes, namely the cross section of the left half groove and the cross section of the right half groove are not symmetric. The aforementioned "cross section" means a section perpendicular to the groove depth direction.
The foregoing has been described: the plug column 203 is matched with the shape of the plug groove 103. The cross-section of the left half and the right half of the bayonet 203 is asymmetric. Therefore, during plugging, the plugging column 203 can only be inserted into the plugging slot 103 according to a fixed angle, so that the plugging column 203 is prevented from being reversely connected with the plugging slot 103, and the positive plug is connected with the negative jack while the negative plug is connected with the positive jack.
Furthermore, the right half groove has two plane groove walls 103a which are separated from each other and arranged in parallel with the groove depth direction of the insertion groove 103, and the two plane groove walls 103a are arranged at a non-zero included angle. While the left half slot does not have these two planar slot walls.
In this embodiment, the two planar slot walls 103a are arranged at an included angle of 97 °.
In this embodiment, the male plug 1 has a first annular end surface 104 located at the notch of the insertion groove 103, the female plug 2 has a second annular end surface 205 located at the periphery of the (rear) end of the insertion column 203, and after the male plug 1 is inserted into the female plug 2, the first annular end surface and the second annular end surface are in abutting contact with each other in the groove depth direction of the insertion groove 103. Therefore, moisture in the environment can be blocked on the outer surfaces of the male plug and the female plug as much as possible.
It should be noted that, in some other embodiments of the present application, the male plug 1 may be connected to an upstream power supply device, and the female plug 2 may be connected to a downstream power consumption device. However, considering that the positive and negative pins in the male plug 1 are more easily touched by people than the conductors inside the positive and negative jacks, it is preferable to connect the male plug 1 to a downstream electric device and the female plug 2 to an upstream electric device to prevent electric shock.
It should be understood that the above-mentioned embodiments are only illustrative of the technical concepts and features of the present application, and the present application is not limited thereto. All equivalent changes and modifications made according to the spirit of the main technical scheme of the application are covered in the protection scope of the application.
