DETAILED DESCRIPTION
[0042] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0043] like Figure 1A , Figure 1B , Figure 2A and Figure 2BAs shown, on one hand, the utility model provides an electrical connector, including a conductive body 1, a first contact body 2 and a driving member 3; the conductive body 1 is arranged in an electronic device; the first contact body 2 is movably arranged at a first end of the conductive body 1; the driving member 3 is arranged on the conductive body 1 and connected to the first contact body 2, and is used to make the first contact body 2 contact with a circuit board 4 in the electronic device and the second end of the conductive body 1 contact with a functional module 5 on the electronic device under the driving action of the driving member 3.
[0044] In this embodiment, the electronic device may include wearable devices such as smart watches, smart bracelets, smart helmets, and smart glasses. Of course, it may also include portable devices such as mobile phones and tablets, and may also be medical detection equipment such as blood pressure monitors and blood glucose meters. The electronic device includes a circuit board 4 placed inside the device and a functional module 5 placed outside the device, wherein the circuit board 4 may integrate components such as chips and resistors for processing data generated by the electronic device. The functional module 5 may include an antenna module, an electrocardiogram detection module, a blood pressure detection module, etc. The antenna module is used to realize data interaction between the electronic device and external devices. In the wearable device, the electrocardiogram detection module and the blood pressure detection module can detect the heart rate and blood pressure of the human body.
[0045] The electrical connector is installed in the electronic device and is used to electrically connect the circuit board 4 and the functional module 5 in the electronic device so that data communication can be achieved between the circuit board 4 and the functional module 5 .
[0046] The conductive body 1 of the electrical connector is used to be installed in the through hole 6 in the electronic device. The conductive material is not limited, and can be conductive metal, conductive plastic, conductive rubber, etc., preferably a metal material. Compared with other materials, the metal material has higher strength and is not easy to deform. It can be easily installed and is not easy to deform during use to ensure good contact between the electrical connector and the circuit board 4 and the functional module 5. The shape of the conductive body 1 is also not limited, and can be a cylinder, a right prism, etc., preferably a cylinder for easy installation.
[0047] The first contact body 2 of the electrical connector may be a metal pin, which is movably mounted on the first end of the conductive body 1 , that is, the first contact body 2 can move relative to the conductive body 1 .
[0048] The driving member 3 is mounted on the conductive body 1 and connected to the first contact body 2, wherein the connection mode can be abutment or fixed connection. The driving member 3 has a driving function, and can make the first contact body 2 and the conductive body 1 move relative to each other so as to contact the circuit board 4 in the electronic device, and also contact the second end of the conductive body with the functional module 5 on the electronic device, wherein the first end and the second end of the conductive body 1 are in a relative position relationship, such as Figure 1B For reference, the first end is located at the top end of the conductive body 1 , and the second end is located at the bottom end of the conductive body 1 .
[0049] like Figure 1B As shown, the driving member 3 can be an elastic member, such as a spring or elastic rubber, and the corresponding driving action is an elastic action. Then, the first contact body 2 is brought into contact with the circuit board 4 in the electronic device under the elastic action, and the second end on the conductive body is brought into contact with the functional module 5 on the electronic device.
[0050] like Figure 3 As shown, the driving member 3 can also be a magnetic member, and the number is at least two, such as two magnets. The corresponding driving action is the magnetic force between the two magnets. Then, the first contact body 2 is brought into contact with the circuit board 4 in the electronic device under the action of the magnetic force, and the second end on the conductive body is brought into contact with the functional module 5 on the electronic device.
[0051] When the first contact body 2 is in contact with the circuit board 4 and the second end is in contact with the functional module 5 , data communication can be performed between the circuit board 4 and the functional module 5 .
[0052] Therefore, by adopting a conductive body to replace the spring connected to the functional module in the prior art, and realizing the docking between the circuit board and the functional module through the driving action of the driving component, during the data communication process, since the conductive body is connected to the functional module, the inductance effect when the current flows is avoided, thereby improving the stability of data communication of the electronic device.
[0053] In one possible implementation, Figure 1B and Figure 4 As shown, a receiving cavity 11 is provided in the conductive body 1 ; a first contact body 2 is disposed in the receiving cavity 11 ; a driving member 3 is installed in the receiving cavity 11 for driving the relative movement between the first contact body 2 and the conductive body 1 .
[0054] In this embodiment, a through hole (not marked in the figure) is provided on the accommodating cavity 11 . The accommodating cavity 11 is opened inside the conductive body 1 , and the through hole is opened at the first end of the conductive body 1 .
[0055] The first contact body 2 and the driving member 3 are both located in the accommodating cavity 11. Specifically, the driving member 3 is completely located in the accommodating cavity 11, and the first contact body 2 is located at the through hole and at least a portion thereof always remains in the accommodating cavity 11. Under the driving action of the driving member 3, the first contact body 2 can be inserted into the through hole and move relative to the conductive body 1 in the driving direction. Furthermore, a boss 21 is provided at the portion of the first contact body 2 remaining in the accommodating cavity 11, and the boss 21 can abut against the first end of the conductive body 1, so that when the boss 21 of the first contact body 2 abuts against the first end of the conductive body 1 during the process of inserting the through hole, the first contact body 2 cannot continue to move outward.
[0056] In one possible implementation, Figure 1B As shown, one end of the elastic member is connected to the inner surface of the accommodating cavity 11 , and the other end is connected to the first contact body 2 .
[0057] In this embodiment, one end of the elastic member, i.e. Figure 1B The bottom end of the elastic member is connected to the inner surface of the accommodating chamber 11, specifically connected to the bottom end of the accommodating chamber 11, wherein the connection mode can be fixed connection or abutment. In addition, the bottom end of the elastic member can also be fixedly connected to the side wall of the accommodating chamber 11.
[0058] The other end of the elastic member, i.e. Figure 1B The top end of the first contact body 2 is connected to the first contact body 2, wherein the connection mode can be abutment or fixed connection. Under the elastic action of the elastic member, the first contact body 2 is driven to pass through the through hole and move outward.
[0059] Preferably, the elastic member is installed in the accommodating cavity 11 in a compressed state, that is, the initial state of the elastic member in the accommodating cavity 11 is a compressed state, so that the elastic member can generate a large elastic force sufficient to drive the first contact body 2 to extend outward, while also preventing the entire first contact body 2 from being easily pressed back into the accommodating cavity 11 and causing a jam.
[0060] In one possible implementation, Figure 3 As shown, the two magnetic members are respectively connected to the inner surface of the accommodating cavity 11 and the first contact body 2, and the magnetic poles repel each other.
[0061] In this embodiment, if the driving member 3 is two magnetic members, one of them is fixedly connected to the inner surface of the accommodating chamber 11, specifically connected to the bottom end of the accommodating chamber 11, and of course, it can also be fixedly connected to the side wall of the accommodating chamber 11.
[0062] Another magnetic member is fixedly connected to the first contact body 2, and the magnetism of the opposite surfaces of the two magnetic members is consistent. When the magnetism is consistent, the two magnetic members repel each other, so that the movement trends of the two magnetic members are opposite, thereby driving the first contact body 2 to move outward through the through hole.
[0063] In one embodiment, reference Figure 1A , Figure 1B and Figure 5 The second end of the conductive body 1 is a second contact body 7; the second contact body 7 is fixedly or movably arranged on the conductive body 1, and is used to contact with the functional module 5 on the electronic device.
[0064] In this embodiment, the second end of the conductive body 1 is a second contact body 7, wherein the second contact body 7 may also be a metal ejector pin.
[0065] The second contact body 7 and the conductive body 1 can be connected in the following manner: Figure 1A and Figure 1B The fixed connection shown can also be as follows Figure 5 When the second contact body 7 is in movable connection, the installation method of the second contact body 7 and the conductive body 1 is the same as the installation method of the first contact body 2, so that the first contact body 2 and the second contact body 7 can move relative to the conductive body 1.
[0066] In one possible implementation, Figure 5 As shown, in the case where the second contact body 7 is movably arranged on the conductive body 1 , one end of the elastic member is connected to the first contact body 2 , and the other end is connected to the second contact body 7 .
[0067] In this embodiment, when the second contact body 7 is movably arranged on the conductive body 1, if the driving member 3 is an elastic member, the two ends of the elastic member are respectively connected to the first contact body 2 and the second contact body 7. Under the elastic action of the elastic member, the first contact body 2 and the second contact body 7 make opposite movements, so that the first contact body 2 passes through the top through hole to connect with the circuit board 4, and the second contact body 7 passes through the bottom through hole to connect with the functional module 5.
[0068] In one possible implementation, Figure 6 As shown, in the case where the second contact body 7 is movably arranged on the conductive body 1, two magnetic members are respectively connected to the first contact body 2 and the second contact body 7, and the magnetic poles repel each other.
[0069] In this embodiment, when the second contact body 7 is movably arranged on the conductive body 1, if the driving member 3 is a magnetic member, the two magnetic members are respectively connected to the first contact body 2 and the second contact body 7. Under the magnetic effect of the two magnetic members, the first contact body 2 and the second contact body 7 move in opposite directions, so that the first contact body 2 is connected to the circuit board 4 through the top through hole, and the second contact body 7 is connected to the functional module 5 through the bottom through hole.
[0070] In one possible implementation, Figure 1B As shown, the accommodating cavity 11 is located at the end of the conductive body 1 close to the first contact body 2 .
[0071] In this embodiment, the entire accommodating cavity 11 is located near the end of the contact body, which can be referred to Figure 1B The upper part of the conductive body 1.
[0072] The second end of the conductive body 1 is a solid structure, that is, the lower half of the conductive body 1, which can be referred to Figure 1B The lower half of the conductive body 1.
[0073] By setting the lower half of the conductive body 1 as a solid structure, the structural strength of the conductive body 1 is fully guaranteed and is not easily damaged by external forces.
[0074] In one possible implementation, Figure 4 As shown, a sealing layer 22 is provided at the perforation of the conductive body 1 to prevent foreign matter outside the accommodating cavity 11 from entering into the accommodating cavity 11 .
[0075] In this embodiment, the sealing layer 22 is specifically a rubber ring, which is located between the perforated side wall and the outer side wall of the first contact body 2 to prevent foreign matter outside the accommodating cavity 11 from entering the accommodating cavity 11, thereby avoiding damage to the driving member 3 or weakening the driving effect.
[0076] In one possible implementation, Figure 1A , Figure 1B and Figure 7 As shown, the conductive body 1 is columnar; a protrusion 12 is provided on the outer side of the conductive body 1 for abutting against a step 61 on the electronic device to limit the maximum distance that the conductive body 1 moves into the electronic device.
[0077] In this embodiment, the conductive body 1 is columnar, specifically cylindrical or prism-shaped, and a protrusion 12 is provided on the outer side of the conductive body 1. The position of the protrusion 12 is specifically located near the second end of the conductive body 1. Correspondingly, a step 61 is provided at a corresponding position at the through hole 6 of the electronic device. During the process of the conductive body 1 being inserted into the through hole 6 for installation, when the protrusion 12 of the conductive body 1 conflicts with the step 61 on the through hole 6, the conductive body 1 will be limited to continue to move into the through hole 6. At this time, the maximum distance of the conductive body 1 is the distance between the first end of the conductive body 1 and the protrusion 12. This can avoid the risk of the circuit board 4 being damaged in some extreme cases, such as when the pressure in the through hole 6 is too large or an external force is applied to the second end of the conductive body 1.
[0078] In one embodiment, when the first contact body 2 is connected to the circuit board 4 , the maximum travel distance between the protrusion 12 and the step 61 is smaller than the maximum distance between the conductive body 1 and the circuit board 4 .
[0079] In this embodiment, the maximum travel distance between the protrusion 12 and the step 61 is set to be smaller than the maximum distance between the conductive body 1 and the circuit board 4, so that when the first contact body 2 is connected to the circuit board 4, if the conductive body 1 continues to move into the through hole 6, the first end of the conductive body 1 will not contact the circuit board 4, so that the circuit board 4 will not be damaged by the impact of the conductive body 1. On the other hand, it also avoids the first contact body 2 being pressed into the accommodating cavity 11 as a whole, resulting in the first contact body 2 rebounding and failing due to damage to the driving member 3 or the first contact body 2.
[0080] In one possible implementation, Figure 1A and Figure 1BAs shown, the second end of the first contact body 2 or the conductive body 1 is a spherical cylinder, so as to be connected with the circuit board 4 or the functional module 5 in a point contact manner.
[0081] In this embodiment, by setting the first contact body 2 or the second end of the conductive body 1 as a spherical cylinder, it can be prevented that the first contact body 2 or the second end of the conductive body 1 accidentally contacts other contacts on the circuit board 4 or in the functional module 5 .
[0082] In one possible implementation, Figure 1A and Figure 1B As shown, the electrical connector further includes a sealing ring 13, which is disposed at a mounting position 14 on the outer side of the conductive body 1, and the sealing ring 13 is mounted on the electronic device in an interference fit manner.
[0083] In this embodiment, the mounting position 14 on the conductive body 1 is an annular groove, the sealing ring 13 is sleeved on the annular groove, and the maximum diameter of the sealing ring 13 is slightly larger than the maximum diameter of the conductive body 1, so that the sealing ring 13 and the electronic device are installed in an interference fit manner, achieving the effect of dustproof, waterproof and moisture-proof.
[0084] Another aspect of the present invention provides a wearable device, such as Figure 3 As shown, it includes an electronic body 8 and the above-mentioned electrical connector; the electronic body 8 includes a circuit board 4 and a functional module 5, wherein the circuit board 4 is located inside the electronic body 8, and the functional module 5 is located outside the electronic body 8; a through hole 6 is provided on the electronic body 8, and the electrical connector is installed in the through hole 6, which is used to connect the circuit board 4 and the functional module 5 so that data communication can be carried out between the circuit board 4 and the functional module 5.
[0085] In this embodiment, the wearable devices include smart watches, smart bracelets, smart helmets, smart glasses, etc.
[0086] The functional module 5 may specifically be an antenna transceiver module, a heart rate detection module, etc., which is fixedly installed on the outside of the electronic body 8 to realize specific functions, such as heart rate detection, signal transmission, etc.
[0087] The circuit board 4 is fixedly installed inside the electronic body 8, and specifically includes a processing chip and other electrical components for processing data in the device; the electrical connector is fixedly installed in the through hole 6 of the electronic body 8, and includes a first end and a second end, which are electrically connected to the circuit board 4 and the functional module 5 respectively, and are used to realize data communication between the circuit board 4 and the functional module 5. For example, when the functional module 5 is a heart rate detection module, the functional module 5 can transmit the detected heart rate data to the circuit board 4 through the electrical connector; when the functional module 5 is an antenna module, the circuit board 4 can transmit information data to the antenna module through the electrical connector, and send it outward through the antenna module.
[0088] Furthermore, the number of the electrical connectors may be one or more. If the number is set to be more than one, they are evenly distributed inside the electronic body 8 .
[0089] In one possible implementation, Figure 7 As shown, a step 61 is provided at the outer end of the through hole 6, and the edge of the step 61 is a chamfered structure to facilitate the disassembly and assembly of the electrical connector.
[0090] In this embodiment, a chamfered structure is provided at the edge of the step 61 to facilitate the first end of the electrical connector to enter the through hole 6 through the chamfered structure, thereby facilitating installation and removal of the entire electrical connector.
[0091] Specifically, when the electrical connector is installed, the first contact body 2 and the conductive body 1 are installed to the designated position through the center of the step 61, and the chamfered structure can better guide the electrical connector; when the electrical connector needs to be separated from the electronic body 8, the chamfered structure can guide the electrical connector to align with the center of the step, making the electrical connector easier to remove.
[0092] In one possible implementation, Figure 2A As shown, the device further comprises a housing 9 .
[0093] In this embodiment, the shell 9 is the external structure of the electronic body 8. For example, during installation, the shell 9 and the electronic body 8 can be bonded together. For example, during installation, the shell 9 and the electronic body 8 can be snap-fitted together, etc., which is not limited here.
[0094] In one possible implementation, Figure 2A As shown, the functional module 5 includes a bottom electrode 51 , and the bottom electrode 51 is threadedly connected to the housing 9 .
[0095] In this embodiment, the bottom electrode 51 is specifically located outside the housing 9 and is used to be electrically connected to the second end of the electrical connector.
[0096] The bottom electrode 51 and the shell 9 are fixed by screws in a threaded connection, which is convenient for disassembly and assembly.
[0097] In one embodiment, a waterproof adhesive layer 62 is provided between the bottom electrode 51 and the housing 9 .
[0098] In this embodiment, after the bottom electrode 51 is fixedly connected to the shell 9, there is generally a gap between the two, which can easily lead to water ingress. A waterproof adhesive layer 62 is provided between the bottom electrode 51 and the shell 9 to achieve a sealing effect.
[0099] In one embodiment, a ring patch (not marked in the figure) is provided at the contact point between the second end of the electrical connector and the bottom electrode 51 .
[0100] In this embodiment, the annular patch can be sleeved around the second end of the electrical connector. After the second end of the electrical connector is connected to the contact point of the bottom electrode 51, the annular patch can prevent liquid or dust from contacting the second end of the electrical connector, achieving the effect of waterproof, moisture-proof and anti-corrosion.
