[0035] At present, the power supply mode of the vehicle refrigerator is usually that the cigar lighter plug with spring sheet and contact is directly inserted into the cigar lighter socket of the automobile. Since the reliability of electrical connection is related to the insertion depth, and the existing cigar lighter plug-in structure cannot provide feedback for the user to plug in place, the cigar lighter plug-in structure may have unstable electrical connection problem, but since the traditional cigar lighter plug-in structure is only used for low-power electrical equipment, the current is small, and even if the power supply is unstable, it will not cause great influence, but for low-voltage high-power vehicle refrigerator, the current is large, if the plug-in is loose or the plug-in is loose, the plug-in is bad, and the risk of striking or fire is easy to appear, at the same time, if the user plugs in the plug with load, there will be the risk of arc.
[0036] Based on this, the utility model provides an electrical connection structure for vehicle refrigerator, aims at solving the problem that the plug-in structure of the existing vehicle refrigerator is easy to appear bad plug-in. Among them, Figure 1 The structure diagram of the electrical connection structure provided by the utility model.
[0037] Please refer to Figure 1 In an embodiment of the utility model, the electrical connection structure 100 includes plug-in structure 1 and detection assembly 2, the plug-in structure 1 includes the plug-in head 11 that can be electrically connected and the socket 12, the socket 12 is equipped with the socket groove 121, the plug-in head 11 is inserted in the socket groove 121, the detection assembly 2 is used to detect the position information of the plug-in head 11 in the depth direction of the socket groove 121.
[0038] The utility model discloses a technical scheme, through setting up the socket groove 121, in order to the plug 11 plug, so that the plug 11 can be installed in the socket 12, so that the plug 11 with socket 12 can be electrically connected, at the same time through setting up the detection component 2, in order to detect the position of plug 11 in the socket groove 121, to determine the insertion depth of plug 11, so that the user can determine whether the plug 11 is loose or plugs in place.
[0039] It can be understood that the detection component 2 also includes a prompting device, so that the user is prompted in time when the detection component 2 determines that the plug 11 is loose or not plugged in place. Further, the prompting device has various forms, for example, it can be a prompt light, a prompt sound or the like, as long as it can remind the user, and the utility model does not limit it.
[0040] In an embodiment of the utility model, the detection component 2 includes a magnet part 21 and a magnetic induction part 22, the magnet part 21 and the magnetic induction part 22 are separately arranged on the plug 11 and the socket 12, so that the insertion depth of the plug 11 is determined through the magnet part 21 and the magnetic induction part 22 cooperating with each other, so as to realize non-contact detection, which can reduce the possibility of wear and failure, and is beneficial to increasing the service life of the detection component 2.
[0041] It can be understood that the detection component 2 has various forms, and in another embodiment, the detection component 2 includes a clamping convex and a clamping groove cooperating with each other, one of the clamping convex and the clamping groove is arranged on the plug 11, and the other is arranged on the socket groove 121, when the clamping convex is clamped into the clamping groove, it can be determined that the plug 11 is plugged in place, so that when the plug 11 is inserted into the socket groove 121, the user can determine whether the plug 11 is plugged in place through the touch feeling or sound when clamping.
[0042] Further, the magnetic induction part 22 has various forms, for example, it can be a Hall element, a Hall switch or the like, and the utility model does not limit it. Specifically, in the embodiment, the magnetic induction part 22 includes a Hall switch, since the utility model only needs to determine whether the plug 11 is loose or plugged in place, it only needs to judge whether the magnetic field exists, and does not need to judge the intensity of the magnetic field, so in the embodiment, the Hall switch is adopted to induct the magnetic field on the plug 11, so as to determine whether the plug 11 is loose or plugged in place through the magnetic field.
[0043] It should be noted that the Hall switch is an electronic component that works by the Hall effect, which can detect the presence or absence of a magnetic field and change the output state (on / off) accordingly. It is usually used as a non-contact proximity switch; while the Hall element is a semiconductor device based on the Hall effect, which can convert the change of magnetic field strength into a voltage signal. Among them, the Hall effect refers to the generation of a potential difference in the direction perpendicular to the current and magnetic field when the current passes through the conductor or semiconductor placed in the magnetic field. This potential difference is called Hall voltage.

[0050] In an embodiment of the utility model, the side of the plug-in connector 11 is provided with a spring piece 4, which is elastically clamped on the inner side wall of the socket groove 121. In this way, the spring piece 4 is arranged to elastically press the plug-in connector 11 in the socket groove 121, so as to prevent the plug-in connector 11 from shaking.
[0051] It should be noted that the above two associated technical features: "the end of the plug-in connector 11 is provided with an electrical connection part 3" and "the side of the plug-in connector 11 is provided with a spring piece 4" can be selectively arranged or simultaneously arranged, and the utility model does not limit this.
