Description

Technical Field

[0001] This utility model relates to the field of physical sensor interface technology, specifically to a connection structure between a probe head and a base interface. Background Technology

[0002] In the field of medical devices, many physical sensors (such as temperature sensors, photoelectric sensors, audio sensors, and pressure sensors) need to be removed from the main unit for individual use to detect human signals, and then returned to the sensor base on the main unit after use. The connection between these sensors and the base needs to perform multiple functions, including powering on / off the sensor, charging it, and facilitating communication.

[0003] In existing technologies, the connection between the probe and the base relies on conductive metal contacts. However, this presents several problems: When the probe is small, the connection contacts (usually conductive metal) between the probe and the base are also small. Accurately aligning and reliably contacting the corresponding contacts on the probe and base when placing it on the base is not easy, requiring precise positioning of the probe. This is especially true when there are multiple functions and numerous contacts, making alignment even more difficult. Poor contact can affect charging, communication, and cause detection malfunctions. Particularly if both the detector and the base are circular without positioning points or devices, it becomes even more difficult to properly connect the corresponding contacts on the base. Furthermore, when the probe is circular and small, handling the sensor is difficult, and it easily slips from the hand.

[0004] Furthermore, since the probe is placed on the base, it is easily detached when the host is moved, either falling to the ground or into the chassis, which can easily lead to damage. Therefore, there is an urgent need for a probe-base interface structure that can solve the above problems. Utility Model Content

[0005] In view of this, the main objective of this utility model is to provide a connection structure between the probe head and the base interface, in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, as a first aspect of this utility model, a connection structure for a probe head and a base interface is proposed, comprising a probe head and a base. The probe head is provided with a plurality of concentrically arranged annular contacts, and the base is provided with a plurality of contact groups corresponding to the annular contacts. The contact groups are configured as a plurality of point contacts. Corresponding positions of the probe head and the base are provided with mutually attractive magnetic rings.

[0007] In this invention, preferably, the base has a receiving cavity for placing the probe.

[0008] In this invention, preferably, the shape of the receiving cavity is adapted to the shape of the probe head, and the shape of the probe head is adapted to the shape of the annular contact.

[0009] In this invention, preferably, the annular contact is shaped as a circle.

[0010] In this invention, preferably, the shape of the annular contact is set to rectangular or curved.

[0011] In this invention, preferably, the number of point contacts in each group of contact points is set to two to five.

[0012] In this invention, preferably, the side of the probe head is provided with a concave groove.

[0013] In this invention, preferably, the outer side of the probe is provided with anti-slip texture.

[0014] In this invention, preferably, both the magnetic ring of the probe and the magnetic ring of the base are permanent magnets.

[0015] In this invention, preferably, the contact point is configured as a spring pin.

[0016] Based on the above technical solution, it can be seen that the connection structure between the probe head and the base interface of this utility model has at least one of the following beneficial effects compared with the prior art:

[0017] 1. By using the interplay between the annular contacts on the probe head and the point contacts on the base, reliable contact is achieved when the probe head is placed into the base at any angle, eliminating the need for precise alignment and solving the problem of difficult multi-contact docking.

[0018] 2. The concave groove and anti-slip texture of the probe improve the stability of hand grip, prevent the probe from slipping, and make it easy and stable to handle;

[0019] 3. The magnetic ring between the probe head and the base can attract the probe head to prevent it from falling off the base when the main unit moves, reducing the risk of damage and ensuring a stable and secure placement. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0029] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0030] The inventor of this utility model discovered that existing technologies suffer from several problems. When the probe is small, the connection points between it and the base are difficult to align accurately due to their small size and large number. This is especially true for circular probes without a positioning device, where the difficulty is even greater, potentially affecting charging and communication. Furthermore, small circular probes are prone to slipping from the hand when handled, and when the main unit is moved, the probe can easily fall off and cause damage. Through in-depth research, it was found that designing the probe and base interface to a compatible shape, using a combination of point and ring contacts—specifically, arranging the point contacts concentrically, creating concave grooves or textured shells on the side of the probe, and installing mutually attracting annular magnetic rings on both the probe and the base—can solve these problems. Therefore, as follows... Figure 1 As shown, this utility model proposes a connection structure between the probe head and the base interface, including:

[0031] The detector head 1 and the base 2 are provided. The detector head 1 has several concentrically arranged annular contacts 3, and the base 2 has several sets of contact groups 4 corresponding to the annular contacts 3. Each set of contact groups 4 consists of several point contacts 5. Magnetic rings 7 attract each other at corresponding positions on the detector head 1 and the base 2, thereby achieving a magnetic connection between the detector head 1 and the base 2. By setting the magnetic rings 7, it is ensured that the detector head 1 will not fall off when placed on the base 2. Figure 3 and Figure 4 As shown. By setting the probe head 1 and the base 2 with different contact methods, the base 2 is set with several point contacts 5, and the probe head 1 is set with ring-shaped contacts 3. Each ring contact 3 of the probe head 1 has a corresponding point contact 5 on the base 2, which can ensure that the probe head 1 and the base 2 are in contact.

[0032] like Figure 2 As shown, in this embodiment, the base 2 further includes a receiving cavity 6 for placing the probe 1. The number of receiving cavities 6 is determined by the number of probes 1. In addition, the receiving cavity 6 also has a reserved cavity for accommodating other different sensors.

[0033] In this embodiment, the shape of the receiving cavity 6 is adapted to the shape of the probe head 1, and the shape of the probe head 1 is adapted to the shape of the annular contact 3. The matching of the shapes of the probe head 1, the receiving cavity 6, and the annular contact 3 is to ensure that the probe head 1 can reliably contact the base 2, and the probe head 1 can be embedded in the receiving cavity 6 for positioning.

[0034] In this embodiment, the annular contact 3 is further configured to be circular, or it can be rectangular or curved. Depending on the shape of the sensor, the base 2 is configured as a corresponding shape of point contact 5, and the probe 1 is configured as a corresponding shape of annular contact 3. This improves the versatility and flexibility of the connection structure between the probe 1 and the base 2. The interface shape can be extended to rectangular or curved, suitable for sensors of different shapes, thus expanding the applicability of the technology.

[0035] like Figure 3 As shown, in this embodiment, the number of contact points 5 in each group of contact points 4 is further set to two to five. When the probe head 1 is placed in the base 2, even if there is a certain angular deviation or slight positional shift, multiple contact points 5 can increase the probability of contact with the corresponding annular contact point 3, avoiding functional failure due to poor contact of a single contact point 5, such as charging interruption or communication failure.

[0036] like Figure 5As shown in this embodiment, the probe head 1 is further provided with a concave groove 8 on its side. This groove facilitates finger gripping and prevents the probe head 1 from falling off. Furthermore, the concave groove 8 can be used on structures such as wristbands or clothing as needed. For example, a wristband may have a circular hole with a radius matching the radius of the concave groove 8, allowing the bottom of the probe head 1 to pass through the hole and the groove 8 to be secured within it. Similarly, if clothing has a similar circular hole design at the corresponding detection point, the bottom of the probe head 1 can also pass through the hole, securing the groove 8 to the clothing. This ensures the probe head 1 is firmly fixed to the detection point, preventing slippage or even detachment due to insecure fixation.

[0037] In this embodiment, the outer side of the probe head 1 is provided with anti-slip texture 9. By providing anti-slip texture 9, the friction force when picking it up can be increased, and the probe head 1 can be prevented from falling.

[0038] In this embodiment, both the magnetic ring 7 of the probe head 1 and the magnetic ring 7 of the base 2 are set as permanent magnets. The magnetic ring 7 of the probe head 1 and the magnetic ring 7 of the base 2 have opposite polarities. This arrangement allows the probe head 1 to be firmly and reliably attracted to the base 2, ensuring that the probe head 1 will not fall off when placed in the receiving cavity 6 of the base 2.

[0039] In this embodiment, the point contact 5 is further configured as a spring pin, which has an elastic extension and retraction function to ensure close contact with the annular contact 3.

[0040] Example 1

[0041] In this embodiment, the annular contact 3 is circular in shape, suitable for small circular sensors in the medical device field, such as temperature probe 1 and pressure probe 1. In the circular interface, two to five point contacts 5 are arranged symmetrically or asymmetrically along concentric circles. This arrangement maintains balance and ensures more even force distribution when the probe 1 contacts the base 2, reducing localized wear or excessive pressure caused by single-point contact and extending the contact's service life. For example, symmetrically arranging two point contacts 5 can form a stable support structure, preventing the probe 1 from tilting on the base 2 due to uneven force distribution, further ensuring contact stability.

[0042] The connection structure includes a circular probe head 1 and a circular base 2. The base 2 has a circular receiving cavity 6 in the middle that matches the shape of the probe head 1, allowing the probe head 1 to be inserted into the receiving cavity 6 for positioning. The probe head 1 and the base 2 are magnetically connected for stable assembly, and electrically connected through a contact structure.

[0043] The bottom of the probe head 1 is provided with 6 sets of concentrically arranged annular contacts 3. Each annular contact 3 is circular, evenly spaced and insulated, and corresponds to the power supply, communication and power on / off control functions respectively. The bottom of the receiving cavity 6 of the base 2 is provided with 6 sets of contact groups 4 that correspond one-to-one with the annular contacts 3. Each set of contact groups 4 is a point contact 5. The point contact 5 adopts a spring needle. The spring needle has an elastic extension and retraction function to ensure close contact with the annular contacts 3.

[0044] Specifically, the magnetic connection structure of this utility model has an annular magnetic ring 7 embedded at the bottom edge of the probe head 1, and a corresponding annular magnetic ring 7 embedded at the inner edge of the receiving cavity 6 of the base 2. The two magnetic rings 7 can be permanent magnets with opposite polarities. For example, the magnetic ring 7 of the probe head 1 is the N pole, and the magnetic ring 7 of the base 2 is the S pole. The probe head 1 is firmly fixed in the receiving cavity 6 by magnetic attraction, preventing it from falling off when the main unit is moved. The anti-slip texture 9 can increase the friction between the fingers and the surface of the probe head 1, further preventing it from slipping when picked up.
