Abstract
Description
Technical Field
[0001] This utility model belongs to the field of temperature control coupler technology, specifically a miniature temperature control coupler with better centering guidance. Background Technology
[0002] In today's rapidly developing society, the small household appliance market is becoming increasingly diverse. Among these, everyday kitchen appliances such as electric kettles, health pots, and formula makers often employ a structure where the base and main body are coupled together. This connection requires a coupler, consisting of upper and lower parts. When placing the main body on the base, the upper and lower couplers must be aligned. Traditional couplers offer almost no guidance, requiring users to rely on intuition to align them, sometimes taking a considerable amount of time. For example, a coupler with authorization announcement number CN208753574U lacks any structure to facilitate alignment between the upper coupler (input socket) and the lower coupler (connector). Users often spend several seconds aligning them, requiring them to hold the main body for an extended period. Given the weight of the main body, this makes operation particularly inconvenient and results in a poor user experience. Utility Model Content

[0006] Preferably, the first inclined guide surface is an inclined guide surface with the inner side concave to the outer side.
[0007] Preferably, the ring width of the first inclined guide surface is 4 mm or more.
[0008] Preferably, the ring width of the first inclined guide surface is 5 mm.
[0009] Preferably, the outermost conductive ring in the groove has an arc-shaped or inclined flange at its opening, which forms a rounded or oblique corner structure at the opening of the groove.
[0010] Preferably, the upper body has a conductive pin at its center, and the conductive pin and the wiring terminal connected to the back are an integral stretch structure, forming a hollow, smooth and seamless column.
[0011] Preferably, the upper body is provided with a through hole for the conductive needle to pass through, and an annular protrusion protruding from the inner surface of the groove is provided at one end of the through hole.
[0012] Preferably, the through hole is provided with an annular protrusion at one end of the back of the upper body.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example
[0025] Please see Figures 1-6 The figure shows a miniature temperature control coupler with improved centering guidance, including an upper body 1 and a lower body 2. The lower surface of the upper body 1 has a groove 11 for accommodating conductive rings 3. Multiple conductive rings 3 are arranged within the groove 11, and each conductive ring 3 has a connecting portion extending to the back side. A first inclined guide surface 12 is provided on the lower surface of the upper body 1 outside the groove 11. At least one insulating protruding ring 13 is provided on the lower surface of the upper body 1, with conductive rings 3 arranged on both its inner and outer sides. This invention, by providing conductive rings 3 on both sides of the insulating protruding ring 13, reduces the spacing between at least one conductive ring 3 compared to existing designs with spaced conductive rings 3. This allows for a smaller overall size and lighter weight for the upper body 1, and also reduces the diameter of the conductive rings 3, decreasing the material used. It also allows for a larger first inclined guide surface 12 on the lower surface of the upper body 1. In this embodiment, the first inclined guide surface 12 is an inclined guide surface with its inner side concave to its outer side.
[0026] In this embodiment, the ring width of the first inclined guide surface 12 is 4 mm or more, preferably 5 mm. In this embodiment, when the outer diameter of the first inclined guide surface 12 is the same as that of the conventional main body 1, the ring width of the first inclined guide surface 12 can reach 5 mm. With the same outer diameter of the main body 1, the ring width of the first inclined guide surface 12 is wider, the guidance is better, and the dimensions of other parts of the main body 1 will be smaller, less material is used, and the weight can be reduced while reducing costs. The diameter of the conductive ring 3 will also be reduced accordingly, and the material used will also be reduced accordingly, further reducing costs.
[0027] In this embodiment, the outermost conductive ring 3 in the groove 11 has an arc-shaped or inclined flange 31 at its opening. The flange 31 forms a rounded or oblique corner structure at the opening of the groove 11. This structure further ensures the guidance between the upper body 1 and the lower seat 2. Since the conductive ring 3 is made of metal, the wear at this point is small, increasing the service life of the product. In addition, the surface of the metal material at this point can be made smoother, which also increases the guiding performance and reduces friction.
[0028] As an additional technical feature of this embodiment, the upper body 1 of this embodiment is provided with a conductive pin 4 at its center. It is worth noting that the conductive pin 4 and the terminal connected to the back are integrally stretched structures, forming a hollow, smooth, and seamless column. There are two traditional structures for the conductive pin 4. One is a separate riveting structure where the conductive pin 4 and the terminal are connected separately. This structure increases the installation process and has the problem of weak conductivity, and the connection is prone to loosening, resulting in poor contact. The other conductive pin 4 also adopts an integral structure, but its column part is formed by bending a plate-shaped piece into a column. This process has splicing seams and is difficult to make round. It is not only unsightly, but also has the problem of poor contact when in contact with the lower body 2. It is also prone to deformation and difficult to process. This embodiment adopts an integral stretched structure, which has a smooth and seamless surface, is more aesthetically pleasing, is not prone to deformation, and does not have the problem of poor contact between the conductive pin 4 and the terminal.
[0029] In this embodiment, the upper body 1 is provided with a through hole 14 for the conductive needle 4 to pass through. At one end of the through hole 14, there is an annular protrusion 16 protruding from the inner surface of the groove 11. The setting of the annular protrusion 16 increases the contact area between the inner wall of the through hole 14 and the conductive needle 4, thereby better ensuring the stability of the conductive needle 4 in the through hole 14.
[0030] In this embodiment, an annular protrusion 15 is provided at one end of the through hole 14 on the back side of the upper body 1. The protrusion further increases the contact area and further ensures the stability of the conductive pin 4. At the same time, the protrusion has a notch 17 facing the installation direction of the wiring terminal integrated with the conductive pin 4. The wiring terminal integrated with the conductive pin 4 is locked in the position of the notch 17, and a positioning mechanism is also provided between the wiring terminal and the back side of the upper body 1. The notch 17 can position the wiring terminal and prevent it from shaking.
[0031] The positioning mechanism described in this embodiment includes a positioning hole on the terminal block and a positioning post on the back of the upper body 1. The terminal block is snapped onto the positioning post, and the axial positioning of the terminal block is held in place by the upper part. This is prior art and will not be described in detail here.
[0032] In this embodiment, it is further noteworthy that the lower seat 2 is provided with a plurality of locking protrusions 21 that are inserted into the groove 11. The upper surface of the locking protrusions 21 is provided with at least a partially concave second inclined guide surface 211. The setting of the second inclined guide surface 211 further improves the guiding performance when the lower seat 2 is coupled with the upper body 1.
