The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] like Figure 2-5The shaving socket shown in the figure comprises a transformer 10 and a base 20; the transformer 10 comprises a frame 11, a pin 12, a coil 13 and an iron core 14; the coil 13 is wound on the frame 11; the iron core 14 is sleeved outside the frame 11 and fixedly connected to the frame 11; the pin 12 of the coil 13 is fixed to the frame 11 and is electrically in contact with and fixedly connected to the wire end 131 of the coil, so that the coil 13 and the pin 12 are electrically connected; here, the wire end of the coil 131 refers to the end of the wire wound into the coil 13; the wire end 131 of the coil can be fixed to the pin 12 by welding; the base 20 of the coil 13 is provided with a slot 21 for plugging with the pin 12; a conductive contact 30 electrically in contact with the pin 12 is provided in the slot 21, so that the pin 12 is electrically connected with the conductive contact 30; the conductive contact 30 can be an existing elastic contact, and the elasticity of the elastic contact ensures that it maintains contact with the pin 12.

[0027] Based on the above structure, the electrical connection between the transformer 10 and the base 20 is realized by the electrical contact between the pin 12 and the conductive contact piece 30, replacing the existing method of realizing electrical connection by using conductive wires, thereby eliminating the need for the following steps: Figure 1 The support portion 80 shown lowers the height of the frame 11 and does not hinder the transformer 10 and the base 20 from getting closer to each other; at the same time, the pin 12 is inserted into the slot 21, which can make the transformer 10 and the base 20 closer together, shortening the distance between the center of the transformer 10 and the base 20, thereby reducing the overall height of the shaving socket, making the shaving socket as small as possible, and saving the installation space of the shaving socket.

[0028] To protect the iron core 14, further, Figure 2 and Figure 4 As shown, the shaving socket further includes a protective shell 40 , in which the iron core 14 is fixed, so as to prevent the iron core 14 from being worn out by external forces; and the frame 11 is fixed on the protective shell 40 , so as to realize the installation of the frame 11 .

[0029] Specifically, the frame 11 is H-shaped, which is convenient for winding the coil 13 , and can limit the position of the coil 13 when the coil 13 is wound, so as to prevent the coil 13 from being separated from the frame 11 .

[0030] Furthermore, if Figure 4As shown, the shaving socket also includes an insulating tape 90; the insulating tape 90 is wound around the coil 13 to cover the coil 13 to avoid leakage; at the same time, the wire end 131 of the coil is exposed from the insulating tape 90 to ensure that the insulating tape 90 can contact the pin 12; here, the existing shaving socket is provided with a conductive lead, so that the conductive lead needs to be wrapped together when the insulating tape 90 is used for wrapping, and in this embodiment, since the conductive lead is omitted, it is not necessary to wrap the conductive lead at this time, which saves the use of the insulating tape 90 and saves costs.

[0031] In order to facilitate the assembly of the transformer 10 and the base 20, as shown in FIG. Figure 3 and Figure 4 As shown, preferably, a first positioning structure 50 is provided on the iron core 14, and a second positioning structure 60 is provided on the base 20; the first positioning structure 50 and the second positioning structure 60 are plug-fitted together, so that when assembling the transformer 10 and the base 20, the relative positioning of the transformer 10 and the base 20 can be achieved by aligning the first positioning structure 50 and the second positioning structure 60, thereby simplifying the alignment operation.

[0032] Specifically, the above-mentioned first positioning structure 50 can be a positioning column fixed on the base 20, and correspondingly, the second positioning structure 60 is a positioning hole opened on the positioning column; however, opening a positioning hole on the iron core 14 will consume a certain amount of material of the iron core 14, reduce the magnetic conductive area of ​​the iron core 14, and affect the magnetic permeability of the iron core 14; therefore, this embodiment preferably adopts the following implementation method, the above-mentioned first positioning structure 50 can be a positioning column fixed on the iron core 14, and the above-mentioned positioning column can be fixed to the base 20 by gluing, melting, screwing, etc.; correspondingly, the second positioning structure 60 is a positioning hole opened on the base 20, and the above-mentioned positioning hole can be formed again after the base 20 is formed; furthermore, the above-mentioned first positioning structure 50 can also be a positioning block, a positioning rod, etc.

[0033] In order to avoid shaking or separation between the transformer 10 and the base 20, preferably, the shaving socket also includes a locking structure 70, which is used to fix the transformer 10 and the base 20, so that relative movement cannot occur between the transformer 10 and the base 20.

[0034] Specifically, the locking structure 70 can be implemented by the following structures: Implementation method 1: the locking structure 70 is an adhesive tape, which is respectively bonded to the transformer 10 and the base 20 by the adhesive tape to achieve relative fixation of the two. However, due to the viscosity limitation of the adhesive tape and the influence of long-term use on the viscosity of the adhesive tape, the stability of this method is poor, that is, the transformer 10 and the base 20 are easily separated from the fixation of the adhesive tape; Implementation method 2: the locking structure 70 includes a buckle and a slot, the buckle is fixed to the transformer 10, and the slot is provided on the base 20, and the buckle and the slot are matched under the action of external force, so that the transformer 10 and the base 20 are fixed; accordingly, the buckle is fixed to the base 20, and the slot is provided on the transformer 10; this embodiment gives priority to the following implementation methods, Implementation method 3: as Figure 2 and Figure 3 As shown, the locking structure 70 includes a through hole 71 provided on the iron core 14, a threaded hole 72 provided on the base 20, and a locking screw 73; the rod portion of the locking screw 73 passes through the through hole 71 and is threadedly engaged with the threaded hole 72, so that by tightening the locking screw 73, the head of the locking screw 73 is pressed against the transformer 10 in a direction close to the base 20, thereby achieving relative fixation of the transformer 10 and the base 20. Compared with the third embodiment, this method has better stability; furthermore, by rotating the locking screw 73, the rod portion of the locking screw 73 can be disengaged from the threaded hole 72, and then the transformer 10 or the base 20 can be replaced.

[0035] Specifically, the through hole 71 passes through the upper and lower surfaces of the iron core 14 .

[0036] In this embodiment, due to the insertion and matching of the pin 12 and the slot 21, the transformer 10 and the base 20 are initially restrained from each other. Therefore, the number of the locking structures 70 can be one or more. In this embodiment, Figure 2 and Figure 3 As shown, there are two groups of locking structures 70, and the two groups of locking structures 70 are symmetrically disposed on opposite sides of the iron core 14. In this way, a stable locking effect on the transformer 10 and the base 20 is ensured. Compared with the method in which locking structures 70 are provided at the four corners of the iron core 14, the number of through holes 71 provided on the iron core 14 is reduced, thereby reducing the material loss of the iron core 14, that is, the magnetic conductive area of ​​the iron core 14 is larger, thereby reducing the thickness of the iron core 14, and further reducing the height of the shaving socket.

[0037] The existing iron core 14 is formed by stacking white sheets of silicon steel sheets. In this embodiment, preferably, Figure 3As shown, the iron core 14 includes a plurality of annealed silicon steel sheets 141, and the plurality of annealed silicon steel sheets 141 are stacked in sequence from top to bottom; the plurality of annealed silicon steel sheets 141 are stacked into a rectangle and have a hollow portion, and the hollow portion is for the skeleton 11 to pass through the iron core 14; any two adjacent annealed silicon steel sheets 141 are fixedly connected, so that the iron core 14 with a fixed shape is formed; since the annealed silicon steel sheets 141 have a higher magnetic permeability than the white sheets, the use of the annealed silicon steel sheets 141 can appropriately reduce the requirements for their number, thereby reducing the thickness of the iron core 14 and further reducing the overall height of the shaving socket; it should be noted here that, according to common knowledge, the white sheet refers to the silicon steel sheet formed without annealing process treatment during production, and the annealed silicon steel sheet 141 refers to the silicon steel sheet formed after annealing process treatment during production.

[0038] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
