Description

Technical Field

[0001] This utility model relates to the field of small household appliances, specifically to the assembly structure of conductive contacts for small household appliances. Background Art

[0002] In meat or similar foods, there is often a significant temperature difference between the surface and the interior, with the center typically being the coldest. To detect the temperature near the center, temperature sensors are often designed with insertable components, such as needle-like wireless temperature probes. These probes are inserted into the food to obtain the temperature of its interior (e.g., the center). A rechargeable battery can be housed within the wireless probe, which is then plugged into the main unit for charging. This requires conductive contacts on the main unit. Additionally, conductive contacts can be added for data connectivity, depending on the requirements. Similar conductive contacts can also be used in small household appliances beyond temperature sensors.

[0003] Current conductive contacts include spring-loaded contacts and pogopins. Spring-loaded contacts offer advantages such as relatively simple components and lower cost, but disadvantages include lower dimensional accuracy, inconsistent spring force, shorter lifespan, and more exposed spring structure, leading to a poor user experience, higher failure rate, and lower aesthetic appeal. Pogopin-type conductive contacts generally consist of three basic components: a needle tube, a needle shaft movable within the needle tube, and a spring positioned between the needle shaft and the needle tube. These components are pre-pressed using precision instruments to form a single assembly. The needle tube can be soldered onto a circuit board. Pogopins generally offer better appearance, user experience, and reliability, but their complexity and higher cost are drawbacks. Utility Model Content

[0004] This invention mainly addresses the technical problem of the difficulty in balancing cost and performance in conductive contact assembly structures.

[0005] In one embodiment, a conductive contact assembly structure is provided.

[0006] A conductive contact assembly structure, comprising:

[0007] A storage base, wherein the storage base is provided with a storage cavity for inserting and removing compatible removable components;

[0008] The storage base includes a housing, a circuit board, contacts, and an elastic element. The circuit board is disposed within the housing, and the contacts are movably disposed on the housing. The contacts are used to abut against corresponding electrodes on the removable component when the removable component is inserted into the storage cavity. The contacts have an initial state and a retracted state during their travel. In the initial state, the contacts protrude from the cavity wall of the storage cavity, and in the retracted state, the contacts have a retraction amount relative to the initial state. The elastic element is disposed between the contacts and the circuit board to apply an elastic driving force to the contacts toward the initial state. The elastic element is a conductive element to make the contacts electrically connected to the circuit on the circuit board.

[0009] In one embodiment, the elastic element is fixed to the contact.

[0010] In one embodiment, the contact has an inner hole on the side away from the receiving cavity, and the elastic element is fixed in the inner hole by an interference fit.

[0011] In one embodiment, the inner hole includes a small-diameter section and a large-diameter section with different diameters. The small-diameter section is located on the side of the large-diameter section closer to the receiving cavity. The elastic element is a helical spring, which is fixed inside the small-diameter section. The diameter of the large-diameter section is larger than the outer diameter of the helical spring.

[0012] In one embodiment, the elastic member includes a support portion located at one end away from the receiving cavity, and the size of the support portion is larger than the size of the adjacent portion in a direction perpendicular to the direction of movement of the contact.

[0013] In one embodiment, the housing is provided with a guide hole for restricting the direction of movement of the contact; the guide hole wall is provided with grooves distributed circumferentially, and the grooves extend axially along the guide hole.

[0014] In one embodiment, the guide hole includes a first guide segment and a second guide segment. The first guide segment is located on the side of the second guide segment close to the receiving cavity. The first guide segment is provided with the groove. The second guide segment is a light hole segment. The diameter of the second guide segment is larger than the diameter of the first guide segment.

[0015] In one embodiment, the housing has a cylindrical portion that protrudes from the housing to the side away from the receiving cavity, and the guide hole is formed by the inner cavity of the cylindrical portion.

[0016] In one embodiment, the outer periphery of the contact is provided with a flange. When the contact is in the initial state, the flange abuts against the housing along the movement direction of the contact to prevent the contact from detaching from the housing under the action of the elastic member.

[0017] In one embodiment, one end of the storage cavity is provided with a plug-in port for inserting and removing the removable component in a plug-in manner. The storage cavity has a first size segment and a second size segment, with the first size segment located on the side of the second size segment near the plug-in port. The contact includes a first polarity contact and a second polarity contact, with the first polarity contact located at the end of the second size segment near the plug-in port and the second polarity contact located at the end of the second size segment away from the plug-in port.

[0018] In one embodiment, at least two second polarity contacts are provided on the side of the second segment away from the insertion port.

[0019] In one embodiment, at least two second polarity contacts are arranged at intervals along the insertion / removal direction of the removable component.

[0020] Secondly, one embodiment provides a temperature detection device.

[0021] A temperature detection device includes a main unit and a temperature probe, wherein the main unit has a conductive contact assembly structure as described in any of the above-described embodiments, and the removable component is the temperature probe.

[0022] The beneficial effects of this utility model are:

[0023] According to the conductive contact assembly structure in the above embodiments, a contact is movably disposed on the housing of the storage base, and the contact can be guided by the housing. The retracted state and the initial state of the contact can respectively match the insertion and removal of the removable component in the storage cavity, thereby realizing the electrical connection between the contact and the removable component. At the same time, the elastic element between the contact and the circuit board is a conductive element, which can realize the conductive connection between the contact and the circuit on the circuit board. Compared with the conductive contact of the spring pin type, the conductive contact assembly structure in this application can achieve similar performance and appearance, but it does not require the setting of a needle tube, nor does it require the assembly of the needle tube, needle shaft and spring by precision instruments, thus achieving a lower cost.

[0039] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art.

[0040] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0041] In the embodiments of this utility model, the contact 130 for forming conductive contacts is movably assembled on the housing 110 of the storage base, and relies on the elastic element 140 to generate an elastic driving force on the removable component and achieve conductive connection with the circuit board 120. The structure is simple, easy to manufacture and assemble, and can achieve a low cost while meeting the current carrying requirements of small household appliances and the performance requirements of conductive contacts.

[0042] Embodiments of the conductive contact assembly structure of this utility model:

[0043] Please refer to Figure 1 and Figure 2 In one embodiment, a conductive contact assembly structure is used for a temperature detection device, which includes a main unit 100 and a temperature probe 200. The main unit 100 can be used as a storage base for the temperature probe 200, and the storage base has a storage cavity 113 for inserting and removing the temperature probe 200, which is a removable component. The cavity wall of the storage cavity 113 has contacts 130, and the temperature probe 200 can be charged by relying on the contacts 130 after being inserted into the storage cavity 113 on the main unit 100. Those skilled in the art will understand that, as needed, some temperature probes 200 can also transmit signals to the main unit 100 through corresponding conductive contacts. After being removed from the storage base, the temperature probe 200 can be inserted into food or other items to detect the temperature of the item. Those skilled in the art will understand that when using the temperature probe 200 for temperature detection, the temperature probe 200 can be connected to the main unit 100 wirelessly to achieve data transmission or other signal connection functions.

[0044] In one embodiment, please refer to Figure 1 and Figure 2The temperature probe 200 has a relatively coarse segment 210 and a relatively fine segment 220. The end of the fine segment 220 has a tapered structure for easy insertion into an object. It should be noted that the terms "coarse" and "fine" in this application refer to a relative comparison of the coarseness of the coarse segment 210 and the fine segment 220. The temperature probe 200 may include a first metal housing 231 and a second metal housing 232, which are spaced apart along the length of the temperature probe 200. The outer surfaces of both housings can respectively form a first electrode and a second electrode. An insulating isolation region is provided between the first electrode and the second electrode, achieving insulation isolation between them. In one specific embodiment, the temperature probe 200 may include an insulating isolator 233. A collar 2331 is provided on the outer circumferential surface of the isolator 233. The first metal housing 231 and the second metal housing 232 are sleeved at both ends of the isolator 233 and located on both sides of the collar 2331, forming an insulating isolation region. The temperature probe 200 has an internal cavity, in which a temperature sensing element can be placed. The specific form of the temperature sensing element is not limited, such as a thermocouple or a temperature sensing chip.

[0045] In some other embodiments, the temperature probe 200 may also have other structural forms, such as a structure with uniform thickness in all parts, and the number and placement of electrodes on it may also be set as needed.

[0046] In one embodiment, the main unit 100 of the temperature detection device may include a housing 110 and a circuit board 120. In a specific embodiment, the housing 110 may include a first housing 111 and a second housing 112, which can form a complete mounting cavity, where the circuit board 120 can be mounted. Additionally, the main unit 100 may include a display module, control buttons, etc. For example, the display module can be used to display the power level, temperature detection value, and set parameters of the temperature detection device, while the control buttons can be used to set the temperature unit and sound level. Of course, in some other embodiments, functional components can be added or removed from the main unit 100 as needed. Furthermore, in some other embodiments, the shape of the main unit 100 is not limited, and the housing 110 can also adopt different structural forms. For example, the housing 110 can be a cylindrical structure, with at least one end of the cylindrical structure having an assembly port for disassembling and assembling components, and a cover can be provided at the assembly port.

[0047] In one embodiment, please refer to Figure 2 and Figure 3The storage cavity 113 is a storage slot located on the side of the first housing 111 away from the second housing 112. A lateral opening 1131 is formed on the side of the first housing 111. The arc of the lateral opening 1131 is smaller than that of a semicircle, which can position the temperature probe 200 and prevent it from falling out of the lateral opening 1131. At the same time, an end opening is formed on the end face of the housing 110, which is a plug-in port 1132 for inserting and removing the temperature probe 200. The lateral opening 1131 in the storage cavity 113 allows for easy observation of the storage status of the temperature probe 200 and also facilitates cleaning of the storage cavity 113.

[0048] It should be noted that in some other embodiments, the receiving cavity 113 may also have other structural forms. For example, the receiving cavity 113 may be formed by a receiving hole on the housing 110, the receiving hole having a complete circumferential hole wall, and the opening of the receiving hole forming a plug-in port 1132 for the temperature probe 200 to be inserted and removed in a plug-in manner. Alternatively, the lateral opening 1131 of the aforementioned receiving groove may be slightly larger than a semicircle, forming an insert groove, which allows the temperature probe 200 to be removed and inserted through the lateral opening 1131.

[0049] like Figure 2 To match the shape of the temperature probe 200, the receiving cavity 113 has a first size segment 1133 and a second size segment 1134. The first size segment 1133 is located on the side of the second size segment 1134 near the insertion port 1132. The first size segment 1133 and the second size segment 1134 are respectively used to adapt to the thicker segment 210 and the thinner segment 220 on the temperature probe 200. The receiving cavity 113 with the first size segment 1133 and the second size segment 1134 can achieve good positioning of the temperature probe 200, avoid the temperature probe 200 from shaking in the receiving cavity 113, and help ensure the user experience.

[0050] In one embodiment, the contact 130 is disposed on a second-sized segment 1134 adapted to the thinner segment 220. Thus, the contacts 130 forming each conductive contact can have the same mounting position along the thickness direction of the circuit board 120, and the travel of each contact 130 and the elastic properties of the elastic element 140 can be consistent, facilitating manufacturing and assembly, and reducing the variety of materials. Of course, in some other embodiments, electrodes can also be disposed on the thicker segment 210 of the temperature probe 200, and the corresponding positions of the contacts 130 on the housing 110 can be adjusted accordingly. Those skilled in the art will understand that each contact 130 can correspond to the thicker segment 210 of the temperature probe 200; or, a portion of each contact 130 can correspond to the thicker segment 210 of the temperature probe 200, and another portion can correspond to the thinner segment 220 of the temperature probe 200. In this case, the elastic element 140 can have different lengths, and / or, the circuit board 120 can be disposed in two locations, with different distances between the two circuit boards 120 and the receiving cavity 113.

[0051] Please refer to Figure 3 In one specific embodiment, the contact 130 includes a first polarity contact 131 and two second polarity contacts 132. The first polarity contact 131 is located at one end of the second dimension segment 1134 near the insertion / removal port 1132, and the second polarity contacts 132 are located at the other end of the second dimension segment 1134 away from the insertion / removal port 1132. During the process of the temperature probe 200 being inserted into and removed from the receiving cavity 113 through the insertion / removal port 1132, the contacts 130 at different positions can respectively form contact with the temperature probe 200. The elastic abutment force of the contacts 130 against the outer peripheral surface of the temperature probe 200 can generate a certain amount of friction, thereby obtaining the corresponding insertion / removal feel. The first polarity contact 131 can be a positive electrode, and the second polarity contact 132 can correspondingly be a negative electrode; or the first polarity contact 131 can be a negative electrode, and the second polarity contact 132 can correspondingly be a positive electrode.

[0052] In some other embodiments, each contact 130 may also be disposed at the same location in the receiving cavity 113, such as on the side near the insertion port 1132, on the side away from the insertion port 1132, or at the middle of the length direction of the receiving cavity 113.

[0053] When the temperature probe 200 is in use, the outer surface of the part of its tip that is inserted into food (e.g., meat) is prone to oil stains. If there is a lot of oil on the temperature probe 200, it may affect the reliable contact between the temperature probe 200 and the contact 130, thereby affecting charging. Therefore, in one embodiment, at least two second polarity contacts 132 are provided on the side of the second dimension segment 1134 away from the insertion / removal port 1132, which helps to ensure a reliable connection between the contact 130 and the temperature probe 200. In a specific embodiment, at least two second polarity contacts 132 are arranged at intervals along the insertion / removal direction of the removable component. If there is a lot of oil on one position of the temperature probe 200 along the aforementioned insertion / removal direction, conductive contact can be achieved at another position. In a specific embodiment, at least two second polarity contacts 132 can also be arranged at intervals circumferentially along the removable component. One of the second polarity contacts 132 can also be used for in-situ detection of the temperature probe 200.

[0054] When the temperature probe 200 is inserted into the receiving cavity 113, the contact 130 abuts against the corresponding electrode on the temperature probe 200 to form a conductive connection. However, the assembly structure of the contact 130 will affect the performance and cost of the contact 130. The specific assembly structure of the contact 130 in this application is described below.

[0055] In the embodiments of this application, the contact 130 is movably disposed on the housing 110. The contact 130 has an initial state and a retracted state during its active stroke. In the initial state, the contact 130 protrudes from the cavity wall of the receiving cavity 113, and in the retracted state, the contact 130 has a retraction amount relative to the initial state. The contact 130 can be a cylindrical structure, and its end near the receiving cavity 113 can be set as a spherical surface so that the retraction can be achieved by relying on the spherical surface during the insertion of the temperature probe 200 into the receiving cavity 113. Of course, in some other embodiments, the end of the contact 130 near the receiving cavity 113 can also be a flat-head structure, an arc-shaped structure, etc. When an arc-shaped structure is used, the center line of the arc surface can be perpendicular to the above-mentioned insertion and extraction direction to facilitate the insertion of the temperature probe 200.

[0056] An elastic element 140 is disposed between the contact 130 and the circuit board 120 to apply an elastic driving force to the contact 130 to move it toward its initial state. When the temperature probe 200 is inserted, the contact 130 is pressed down by the temperature probe 200 and retracts. When the temperature probe 200 is pulled out of the receiving cavity 113, the contact 130 pops out under the elastic driving force of the elastic element 140. Please refer to... Figure 4Although the temperature probe 200 is installed in the receiving cavity 113 at this time, the contact 130 in the figure is shown in its initial state. The dimension in which the contact 130 and the temperature probe 200 overlap along the direction of movement of the contact 130 is the fitting amount between the contact 130 and the temperature probe 200, which is also the amount of retraction of the contact 130 in the corresponding retracted state relative to the initial state. Of course, the above fitting amount can be adjusted as needed.

[0057] To facilitate the assembly of the contact 130, in one embodiment, the housing 110 is provided with a guide hole 1141, which penetrates the cavity wall of the receiving cavity 113. The contact 130 is movably assembled within the guide hole 1141, which restricts the direction of movement of the contact 130. In another specific embodiment, the housing 110 is provided with a cylindrical portion 114, which protrudes from the housing 110 away from the receiving cavity 113. The guide hole 1141 is formed within the inner cavity of the cylindrical portion 114. Using the cylindrical portion 114 to form the guide hole 1141 ensures the axial dimension of the guide hole 1141, thereby providing sufficient travel for the contact 130 without increasing the wall thickness of the receiving cavity 113.

[0058] To ensure reliable contact between the contact 130 and the temperature probe 200, the elastic element 140 needs to provide sufficient elastic driving force and sufficient driving stroke. However, excessive driving stroke of the elastic element 140 can easily cause the contact 130 to disengage from the guide hole 1141. Therefore, in some embodiments, a flange 133 is provided on the outer periphery of the contact 130. When the contact 130 is in its initial state, the flange 133 abuts against the housing 110 along the direction of movement of the contact 130 to prevent the contact 130 from disengaging from the housing 110 under the action of the elastic element 140. Figure 4 , Figure 6 and Figure 7 The flange 133 can be annular and is disposed at one end of the contact 130 near the circuit board 120. In one specific embodiment, the flange 133 can also be disposed in the middle of the contact 130 in the direction of movement, and the flange 133 can be arranged at intervals along the circumference of the contact 130.

[0059] In some embodiments, grooves 1142 distributed circumferentially may be provided on the wall of the guide hole 1141, and the grooves 1142 extend axially along the guide hole 1141. Providing grooves 1142 can reduce the contact area between the contact 130 and the guide hole 1141, and prevent unevenness of the surface of the contact 130 and / or the wall of the guide hole 1141 from affecting the smooth movement of the contact 130. In one embodiment, the guide hole 1141 includes a first guide section 1143 and a second guide section 1144. The first guide section 1143 is located on the side of the second guide section 1144 near the receiving cavity 113. The first guide section 1143 is provided with a groove 1142. The second guide section 1144 is a light hole section. The diameter of the second guide section 1144 is larger than the diameter of the first guide section 1143. The end of the first guide section 1144 away from the receiving cavity 113 can be abutted by the flange 133 on the outer periphery of the contact 130 to block the contact 130. The second guide section 1144 can avoid the flange 133 on the contact 130, ensuring the smooth movement of the contact 130, and can limit the position of the contact 130 and the elastic member 140 to prevent the contact 130 and the elastic member 140 from being misaligned.

[0060] In some embodiments, the elastic element 140 is a conductive element, enabling the contact 130 to be electrically connected to the circuitry on the circuit board 120. Those skilled in the art will understand that, as an example, the elastic element 140 can be a helical spring, which has a simple structure and low cost. As an example, pads can be provided on the circuit board 120 for the elastic element 140 to contact and achieve a conductive connection.

[0061] In one specific embodiment, the elastic member 140 includes a support portion 141 located at one end away from the receiving cavity 113. In a direction perpendicular to the direction of movement of the contact 130, the size of the support portion 141 is larger than the size of the adjacent portion, thereby providing a larger support area for the elastic member 140. This helps prevent the elastic member 140 from tilting and also improves conductivity. Figure 4 , Figure 6 , Figure 7 One end of the helical spring has a larger diameter, forming the aforementioned support portion 141. In some other embodiments, the elastic element 140 can also be of other structural forms, such as conductive rubber, conductive spring sheet, etc. When a conductive spring sheet is used, when the contact 130 is in its initial state under the action of the conductive spring sheet, the conductive spring sheet can still have a large amount of elastic deformation to ensure the positional accuracy of the contact 130.

[0062] To facilitate the installation of the contact 130 and the elastic element 140, in some embodiments, the elastic element 140 is fixed to the contact 130 and can be integrally assembled onto the housing 110. The fixing structure between the elastic element 140 and the contact 130 is not limited, such as interference fit, adhesive bonding, threaded connection, snap-fit ​​connection, etc.

[0063] In one specific embodiment, the contact 130 has an inner hole 134 on the side away from the receiving cavity 113, and the elastic element 140 is fixed in the inner hole 134 by an interference fit. The inner hole 134 facilitates the positioning between the elastic element 140 and the contact 130, and also facilitates good conductive contact between the elastic element 140 and the contact 130. In some other embodiments, the contact 130 may also be a solid structure. Additionally, in some other embodiments, a guide post may be provided at the end of the contact 130 away from the receiving cavity 113, and the elastic element 140 can be sleeved onto the guide post.

[0064] When the contact 130 has an inner hole 134, the elastic element 140 can be interference-fitted into the inner hole 134. In one embodiment, the inner hole 134 may include a small-diameter section 1341 and a large-diameter section 1342 with different diameters, the small-diameter section 1341 being located on the side of the large-diameter section 1342 closer to the receiving cavity 113. The elastic element 140 in the form of a coil spring is fixed in the small-diameter section 1341 by interference fit, and the diameter of the large-diameter section 1342 is larger than the outer diameter of the coil spring. The small-diameter section 1341 and the large-diameter section 1342 not only achieve the fixation of the elastic element 140 to the contact 130, but also avoid excessive fixation of the elastic element 140 by the inner hole 134 on the contact 130, which helps to ensure the elasticity of the elastic element 140.

[0065] In the embodiments of this application, the housing 110 can replace the metal encapsulation shell (i.e., needle tube) of the pogopin, and can eliminate the welding process of the pogopin, but can retain the core conductive contact structure of the pogopin and the structure that relies on the elastic element 140 to provide elastic driving force. This is beneficial to meet the contact reliability, extension life and aesthetic function of conductive contacts in small household appliances, ensure contact reliability and insertion and removal friction experience, and save costs and assembly processes.

[0067] The structure of the temperature detection device can be the same as that of the temperature detection device corresponding to the above-mentioned conductive contact assembly structure, and will not be described in detail here.

[0068] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
