DETAILED DESCRIPTION

[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0027] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it may be directly on the other component or there may also be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in the specification of this application are for illustrative purposes only and do not represent the only implementation method.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are indirectly in contact through an intermediate medium. Moreover, a first feature being “above”, “above” or “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below” or “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0030] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0031] See also Figures 1 to 4 The present application provides a power plug-in for electrically connecting an electrical appliance to a car power supply. The power plug-in includes a housing 10, an input terminal 20, and an output terminal 30. The input terminal 20 is provided on the housing 10 and is used to be plugged and electrically connected to the car power supply. The output terminal 30 includes at least a first output terminal 31 and a second output terminal 32, and the first output terminal 31 and the second output terminal 32 are used to be plugged and electrically connected to the electrical appliance respectively. The first output terminal 31 and the second output terminal 32 are both provided on the housing 10 and are electrically connected to the input terminal 20 respectively.

[0032] It is understandable that the output terminal 30 can be set to two or more. In other embodiments, the output terminal 30 can also include a third output terminal 30, a fourth output terminal 30, etc. In this embodiment, it is preferably set to two, namely a first output terminal 31 and a second output terminal 32. When two external electrical appliances need to use the car power supply, they only need to be plugged into the first output terminal 31 and the second output terminal 32 through their wiring harness ends, and the first output terminal 31 and the second output terminal 32 can be electrically connected to the car power supply respectively, so as to meet the power demand of the two external electrical appliances at the same time.

[0033] Further, the plugging direction of the first output terminal 31 is defined as the first direction, and the plugging direction of the second output terminal 32 is defined as the second direction. The first direction and the second direction can be set in parallel, overlapped or intersecting. In this embodiment, the first direction and the second direction are set in parallel. When the same direction is set, the operation of plugging the wiring harness end of the external electrical appliance is more convenient.

[0034] For example, the first direction and the second direction are arranged in opposite directions, so that there is a certain distance between the plugging positions of the first output terminal 31 and the second output terminal 32, and the operation space when plugging the wiring harness end of the external electrical appliance is larger, and the operation is easier.

[0035] Exemplarily, the plugging direction of the input terminal 20 is defined as the third direction, and the third direction is perpendicular to the first direction and the second direction. In this embodiment, the first output terminal 31 and the second output terminal 32 are symmetrically arranged with the third direction as the axis. That is, the input terminal 20, the first output terminal 31, and the second output terminal 32 are in a T-shaped structure, which greatly compresses the volume of the power plug-in, reduces the plug-in cost and space occupation.

[0036] Specifically, Figure 2 As shown, the housing 10 includes an input housing 11, a first output housing 12, and a second output housing 13. The input housing 11, the first output housing 12, and the second output housing 13 are all hollow structures and are interconnected. The input end 20 is arranged in the input housing 11, the first output end 31 is arranged in the first output housing 12, and the second output end 32 is arranged in the second output housing 13, so that the input end 20, the first output end 31, and the second output end 32 are isolated and protected by the housing 10. Optionally, the input end 20, the first output end 31, and the second output end 32 can all use directly purchased terminals, and are electrically connected to each other through wires.

[0037] In one embodiment, the housing 10 further includes a connection base 14, which is connected to the input housing 11 and is provided with a connection hole 141. During installation, the connection base 14 can be fixed to the installation position of the power plug-in by passing screws, bolts, etc. through the connection hole 141, so that the power plug-in can be firmly installed.

[0038] Exemplarily, the connection seat 14 is disposed at the bottom of the input housing 11, and the connection seat 14 and the input housing 11 can be connected by integral molding, welding, bonding, etc. Preferably, in this embodiment, the connection seat 14 and the input housing 11 are integrally molded, which is easier to process.

[0039] Optionally, the connection holes 141 are provided in plurality, and the number can be selected to be two, three, four, etc., preferably four, so that the connection is more stable.

[0040] In one embodiment, if Figure 3 As shown, a first guide structure 40 is provided on the first output housing 12 for guiding the plugging of the first output terminal 31 with the electrical appliance, thereby ensuring smooth matching between the wiring harness end of the external electrical appliance and the first output terminal 31 .

[0041] Specifically, the first guide structure 40 includes a first guide rail 41 and a first lock 42. The first guide rail 41 is disposed on the outer wall of the first output housing 12 and protrudes from the outer wall of the first output housing 12. A slot may be provided at a position corresponding to the first guide rail 41 on the wiring harness end of the external electrical appliance.

[0042] It is understandable that when the wiring harness end is plugged into the first output end 31 , the first guide rail 41 will always slide along the slot, thereby preventing the wiring harness end from being offset during the plugging process, thereby allowing the wiring harness end to be plugged into the first output end 31 smoothly.

[0043] Furthermore, the first lock buckle 42 is also provided on the outer wall of the first output housing 12, and the first lock buckle 42 can be engaged with the electrical appliance. The first lock buckle 42 can adopt a triangular protrusion, a protrusion, a hook-shaped protrusion or the like, and a groove can be provided on the wiring harness end of the external electrical appliance corresponding to the first lock buckle 42.

[0044] It is understandable that when the wiring harness end is plugged into the first output end 31 , the first lock buckle 42 can be snapped into the slot, thereby preventing the wiring harness end from being disengaged from the first output housing 12 and ensuring stable plugging of the wiring harness end with the first output end 31 .

[0045] In one embodiment, if Figure 4 As shown, a second guide structure 50 is provided on the second output housing 13 for guiding the plugging of the second output terminal 32 and the electrical appliance, thereby ensuring smooth matching between the wiring harness end of the external electrical appliance and the second output terminal 32 .

[0046] Specifically, the second guide structure 50 includes a second guide rail 51 and a second lock 52. The second guide rail 51 is disposed on the outer wall of the second output housing 13 and protrudes from the outer wall of the second output housing 13. A slot may be provided at a position corresponding to the second guide rail 51 on the wiring harness end of the external electrical appliance.

[0047] It is understandable that when the wiring harness end is plugged into the second output end 32 , the second guide rail 51 will always slide along the slot, thereby preventing the wiring harness end from being offset during the plugging process, thereby allowing the wiring harness end to be plugged into the second output end 32 smoothly.

[0048] Furthermore, the second lock buckle 52 is also arranged on the outer wall of the second output housing 13, and the second lock buckle 52 can be engaged with the electrical appliance. The second lock buckle 52 can adopt a triangular protrusion, a protrusion, a hook-shaped protrusion or the like, and a groove can be arranged on the wiring harness end of the external electrical appliance corresponding to the second lock buckle 52.

[0049] It is understandable that when the wiring harness end is plugged into the second output end 32 , the second lock buckle 52 can be snapped into the slot, thereby preventing the wiring harness end from being disengaged from the second output housing 13 , thereby ensuring stable plugging of the wiring harness end with the second output end 32 .

[0050] In order to distinguish the first output terminal 31 from the second output terminal 32, the first guide rail 41 and the second guide rail 51 are arranged at different positions. Preferably, the first guide rail 41 is arranged at the upper position of the output housing, and the second guide rail 51 is arranged at the lower position of the output housing, which can be distinguished intuitively.

[0051] The present application also provides a car, which adopts the power plug-in in any one of the above embodiments.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
