Description

Technical Field

[0001] The present application belongs to the technical field of electronic products, and in particular, relates to a connector and an electronic device. Background Art

[0002] Pogo pins, also known as spring pins, are widely used for precision connection in electronic products such as mobile phones, portable electronic devices, communications, automobiles, medical treatment, and aerospace. Pogo pins are mainly used for current and signal transmission, that is, charging and conducting. Traditional pogo pins usually include three basic components: a needle shaft, a spring, and a needle tube. The needle shaft moves along the length of the needle tube inside the needle tube to achieve circuit conduction.

[0003] Movement at an angle to the length of the needle tube is usually achieved through sliding friction between the spring pin and the contact surface, which may cause the needle shaft of the spring pin to wear or bend, resulting in the spring pin being unable to be used normally, or even causing the product to be unable to charge and fail to function. Utility Model Content

[0004] The embodiments of the present application provide a connector and an electronic device to make up for the deficiencies of the prior art.

[0006] A first ball is installed in the first accommodating cavity and close to the first opening;

[0007] A first elastic member is disposed in the first accommodating cavity and located between the first shell and the first ball;

[0008] The first ball has a first state and a second state. In the first state, a part of the structure of the first ball protrudes from the first opening. In the second state, the first ball moves toward the direction close to the first elastic member to compress the first elastic member.

[0009] In a second aspect, an embodiment of the present application provides an electronic device, including: a connector described in any one of the above implementations and embodiments.

[0010] In the connector provided in the embodiment of the present application, the first ball can withstand downward pressure in different directions by rotating. Compared with the traditional needle shaft contact solution, the circuit conduction is achieved by the first ball in the embodiment of the present application, and it also has the following effects: First, when cleaning, the first ball is not easy to hook the clean cloth relative to the needle shaft, which is convenient for cleaning. Second, the first ball partially protrudes from the first opening, and the first ball is not easy to bend after being subjected to pressure relative to the needle shaft, thereby extending the service life. Third, there is ball contact between the first ball and the related components, and the ball contact can achieve conduction in any direction of movement. Thereby improving the motion contact performance of the connector at any angle, so that it can work normally in any angle motion scene. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0027] Pogo pin, also known as spring pin, is widely used for precision connection in electronic products such as mobile phones, portable electronic devices, communications, automobiles, medical treatment, aerospace, etc. Pogo pin (spring pin) is mainly used for current and signal transmission, that is, charging and conducting. Traditional pogo pin usually includes three basic components: needle shaft, spring, and needle tube. The needle shaft moves in the needle tube along the length direction of the needle tube to achieve circuit conduction. As for the movement at an angle to the length direction of the needle tube, it is usually achieved by sliding friction between the spring pin and the contact surface, which may cause the needle shaft of the spring pin to wear or bend, causing the spring pin to fail to work normally, and even cause the product to be unable to charge and malfunction.

[0028] Since the needle shaft is usually a long and thin needle, it is easy to bend due to external pressure, which makes it unable to move up and down normally, or even unable to work normally, which brings a series of problems, such as difficulty in cleaning and transportation. Specifically, for example, when using a cleaning cloth to clean the spring needle, the needle shaft is likely to be hooked on the fibers of the cleaning cloth, causing the needle shaft to bend due to force. For another example, when transporting the spring needle, it is also necessary to prevent the needle shaft from being bent due to pressure.

[0029] To solve the above problems, on the one hand, an embodiment of the present application provides a connector, which may include a first housing 10, a first ball 40 and a first elastic member 30, wherein the first housing is used to mount the first ball and the first elastic member. Figure 1 , wherein the first shell 10 is provided with a first accommodating cavity 11 and a first opening 13 which are interconnected; the first ball 40 is installed in the first accommodating cavity 11 and is arranged near the first opening 13, and the first ball 40 is movably installed in the first shell 10, in other words, the first ball 40 can move along the axial direction of the first shell. In the embodiment of the present application, the first ball 40 can be a steel ball or a metal ball, etc., and the first ball 40 needs to have good conductivity. In other embodiments, the surface of the first ball 40 can also be electroplated with gold, which is not specifically limited in the present application. The first elastic member 30 is arranged in the first accommodating cavity 11 and is located between the first shell 10 and the first ball 40. The first elastic member 30 can be retracted and retracted. For example, when subjected to external pressure, the first elastic member 30 can be compressed; when the pressure is removed, the first elastic member 30 can return to a normal state. In some specific embodiments, one end of the first elastic member 30 can be pressed against the first ball 40, and the other end of the first elastic member 30 can be pressed against the first shell 10, so that when the first ball 40 is subjected to external pressure, the first ball 40 retracts, and the first ball 40 compresses the first elastic member 30, so that the first elastic member 30 changes from an initial state to a compressed state, and when the external pressure is removed, the originally compressed first elastic member 30 has a tendency to restore the initial state, thereby pushing a part of the structure of the first ball 40 to protrude from the first opening 13. In some embodiments, the first elastic member can be a spring.

[0030] The first ball 40 has a first state and a second state, and the first state and the second state of the first ball 40 can be achieved in cooperation with the first elastic member 30. Figure 1 , Figure 1 The first ball 40 in the first state is in the first state. Figure 1 , Fig.12 In the first state, a part of the structure of the first ball 40 protrudes from the first opening 13, and pressure from an external device can be applied to the first ball 40 protruding from the first opening 13; please refer to Fig.13 , Fig.13 When the first ball 40 is in the second state, the first ball 40 moves toward the direction close to the first elastic member 30, thereby compressing the first elastic member 30. During operation, some electronic components of the electronic device can be electrically connected to the first housing, and the first ball 40 can abut against the external device to form an electrical connection, thereby making the electronic components of the electronic device electrically connected to the external device, thereby realizing functions such as data transmission and power supply between different devices.

[0031] Please combine Figure 1 , Fig.12 , Fig.13 When the external device abuts against the first ball 40 in the first state, the first ball 40 can move toward the inside of the first housing 10 (or the direction in which the first housing 10 is away from the first opening 13) and compress the spring, and the first ball 40 is in the second state. When the external device is separated from the first ball 40, the first elastic member 30 can elastically recover to drive the first ball 40 in the second state to move toward the first opening 13 of the first housing 10 until it returns to the first state.

[0032] In the embodiment of the present application, the first ball 40 can contact other devices under the elastic stress of the first elastic member 30, so as to realize the conduction of the circuit. Due to the scalability of the first ball 40, the installation error and the gap caused by the looseness of the connector and other devices during the installation process can be effectively compensated, so that the first ball 40 can always be in contact with the device, thereby improving the reliability and effectiveness of the circuit conduction. In the embodiment of the present application, the first ball 40 can rotate relative to the first shell 10. Since the shape of the first ball 40 is spherical, it can be rotated at any angle to form a spherical contact terminal, so that the first ball 40 can be contacted and conducted in any direction, and the scope of application of the connector; at the same time, the first ball 40 can withstand the downward pressure in different directions by rotating. Compared with the traditional needle shaft contact solution, the circuit conduction is realized by the first ball in the embodiment of the present application, and the following effects are also achieved: First, when cleaning, relative to the needle shaft, the first ball is not easy to hook the clean cloth, which is convenient for cleaning. Second, the first ball part protrudes from the first opening 13, and the first ball is not easy to bend after being subjected to pressure relative to the needle shaft, so that the service life is longer. Thirdly, the first ball and the related device are in ball contact, and the ball contact can achieve conduction in any direction of motion, thereby improving the motion contact performance of the connector at any angle, so that it can work normally in any angle motion scene.

[0033] In some embodiments, the inner diameter of the first opening 13 is R1, and the diameter of the first ball 40 is R2, where R1 is smaller than R2. Thus, the first opening 13 can limit the first ball 40 in the first shell 10 to prevent the first ball 40 from falling out of the first opening 13 of the first shell 10.

[0034] Please combine Figure 1 , Figure 5 In some embodiments, the connector may further include a first inner shaft 20, which is installed in the first accommodating cavity 11, and the opposite ends of the first inner shaft 20 are respectively abutted against the first elastic member 30 and the first ball 40. Under the elastic stress of the first elastic member 30, the first elastic member 30 can push the first inner shaft 20, and the first inner shaft 20 further pushes the first ball 40, so that part of the structure of the first ball 40 protrudes from the first opening 13, thereby better realizing the above-mentioned "in the first state, part of the structure of the first ball 40 protrudes from the first opening 13". This facilitates the first ball 40 to contact and conduct with other devices.

[0035] In addition, when external pressure is applied to the first ball 40 in the first state, the first ball 40 can push the first inner shaft 20, and the first inner shaft 20 further pushes the first elastic member 30, so that the first elastic member 30 is compressed. By providing the first inner shaft 20, the pressure of the first ball 40 can be more evenly transmitted to the first elastic member 30. In addition, the surface of the first inner shaft 20 opposite to the first ball 40 can be configured as a plane, so that the first ball 40 can roll easily.

[0036] Please combine Figure 1 , Figure 5 In some embodiments, the surface of the first inner shaft 20 opposite to the first elastic member 30 is a first inclined surface 21 , and the first inclined surface 21 extends along the axial direction of the first shell 10 , away from the direction of the first ball 40 .

[0037] In some embodiments, the surface of the first inner shaft 20 opposite to the first elastic member 30 is a first inclined surface 21. Figure 5It can be seen that the inclined surface 21 is inclined roughly along its radial direction. When the compressed first elastic member 30 returns to its initial state, the first elastic member 30 pushes the first inner shaft 20 to move toward the direction close to the first opening 13. Since the surface of the first inner shaft 20 opposite to the first elastic member 30 is the first inclined surface 21, the first inner shaft 20 moves toward the direction close to the first shell 10 and can abut against the first shell, thereby achieving better conduction. Among them, in some specific embodiments, the inclination angle of the first inclined surface can be 15 degrees to 20 degrees. Better conduction can be achieved. Exemplarily, the inclination angle of the first inclined surface can be 15 degrees, 16 degrees, 17 degrees, 18 degrees, 19 degrees, and 20 degrees.

[0038] In some embodiments, the first shell 10 includes a first shell 15 and a base 17, and the first shell 15 is detachably connected to the base 17, so as to facilitate installation and replacement of parts. In some specific embodiments, the first shell 15 and the base 17 can also be riveted, clamped, etc., and the embodiments of the present application are not limited to this. The first accommodating cavity 11 can be formed between the first shell 15 and the base 17, and the first opening 13 is provided at the end of the first shell 15 away from the base 17, and the first elastic member 30 is located between the base 17 and the first ball 40. One end of the first elastic member 30 abuts against the side of the base 17 facing the first shell 15, and the other end of the first elastic member 30 can abut against the first inner shaft 20, and the end face of the first inner shaft 20 away from the first elastic member 30 abuts against the first ball 40.

[0039] Please combine Figure 1 In some embodiments, the first base 17 has a first mounting groove 170 on one side close to the first ball, one end of the first elastic member 30 is mounted in the first mounting groove 170 and abuts against the bottom wall of the first mounting groove 170, and the other end of the first elastic member 30 abuts against the first inner shaft. In this way, the first mounting groove 170 can accommodate part of the first elastic member 30, so that the electronic device including the connector can be made thinner and smaller in size.

[0040] Please combine Figure 1 In some embodiments, a bump may be fixed on the side of the base away from the first ball, and the bump extends in a direction away from the base. The bump is mainly used to connect with other devices, such as a circuit board, to facilitate electrical conduction.

[0041] Among them, mounting blocks may be protruded on both sides of the bottom wall of the first mounting groove 170 to cooperate with the first housing 15. During installation, the first housing 15 may be sleeved on the peripheral side of the side wall of the first mounting groove 170 to achieve assembly of the first housing 15 and the first base 17. The mounting blocks may be specifically arranged around the peripheral side of the bottom wall of the groove, so that when the connector is assembled with other components, the base can be placed steadily by the mounting blocks, and then further assembled with other components.

[0042] Please combine Figure 1 In some embodiments, the first accommodating cavity is in the shape of a cylinder. Specifically, the first shell in the embodiment of the present application may be provided with a first accommodating cavity 11 and a first opening 13 that are interconnected; the first accommodating cavity 11 is in the shape of a cylinder, which is used to install the first elastic member, the first inner shaft 20 and other structures, and the position close to the first opening 13 is used to install the first ball 40. During assembly, the first ball, the first inner shaft 20 and the first elastic member 30 are respectively installed in the first outer shell 15, so that the first ball, the first inner shaft 20 and the first elastic member 30 can move in the space defined in the first outer shell 15, and then the first base is installed, and then the first base and the first outer shell 15 can be riveted.

[0043] Among them, in some embodiments, the first housing, the first inner shaft 20 and the first ball bearing can all be made of conductive materials, such as stainless steel or other metals, so that the connector provided in the embodiment of the present application can have good electrical conductivity to facilitate the transmission of current or signals. Exemplarily, when the connector is connected to the conductive part of another device, the current can flow to the first inner shaft 20 through the first ball bearing, and then flow to the first housing and flow to another device, such as a circuit board, through the protrusion fixed on the side of the base away from the first ball bearing.

[0044] Please combine Figure 1 In some embodiments, the shape of the end of the first housing 15 away from the base 17 is arc-shaped. When the first ball 40 partially protrudes from the first opening 13, the arc-shaped outer wall of the first ball 40 matches with the end of the first housing 15 away from the base 17. In the embodiment of the present application, the shape of the end of the first housing 15 away from the base 17 is configured as an arc, so that the first ball 40 and the end of the first housing 15 away from the base 17 can better match.

[0045] Furthermore, please combine Figure 2 , Figure 3 , Figure 4 as well as Figure 5 , Figure 2 A perspective view of a second embodiment of a connector provided by the present application; Figure 3 for Figure 2A schematic structural diagram of a connector at one angle; Figure 4 for Figure 2 A schematic structural diagram of the connector from another angle; Figure 5 for Figure 4 According to actual needs, the above connectors can also be assembled through a bracket M, that is, made into a module structure for user convenience.

[0046] Based on the structure of the connector described above, in order to broaden the use scenarios of the connector, a double-headed connector is further provided in the embodiment of the present application. The connector can be configured according to actual needs, and can be configured as a symmetrical structure, with the two ends of the connector having the same structure, or an asymmetrical structure. According to actual needs, the two ends of the connector can be configured as different structures, and the embodiment of the present application does not limit this.

[0047] The following is an example of a specific structure of a connector: the base of the connector may be a symmetrical structure, so that the symmetry axis of the base is used as the symmetry axis of the connector. Figure 6 , Figure 7 The connector also includes a second shell 50, which is installed on the side of the base 17 away from the first ball 40, and the second shell is provided with a second accommodating chamber 51 and a second opening 53 which are interconnected; a second inner shaft 60, which is installed in the second accommodating chamber 51, and a second elastic member 70, which is arranged in the second accommodating chamber 51, and one end of the second elastic member 70 is abutted against the side of the base 17 away from the first ball 40, and the other end is abutted against the second inner shaft 60; a second ball 80, at least part of the structure of the second ball 80 is abutted against the surface of the second inner shaft 60 away from the second elastic member 70, and the second ball 80 has a third state and a fourth state. In the third state, at least part of the structure of the second ball 80 protrudes from the second opening 53, and in the fourth state, the second ball 80 moves toward the side of the second inner shaft 60 and compresses the second elastic member 70.

[0048] The base 17 of the connector may be a symmetrical structure, so that one side of the base is provided with the first shell 10, the first ball 40, the first elastic member 30 and other structures, and the other side of the base is provided with the second shell, the second ball, the second elastic member and other structures. The structures on both sides of the connector base may be completely consistent, for example, the first shell 10 has the same structure as the second shell, the first ball 40 has the same structure as the second ball, and the first elastic member 30 has the same structure as the second elastic member.

[0049] Furthermore, a first mounting groove is provided on the side of the base 17 of the connector close to the first ball, one end of the first elastic member 30 is installed in the first mounting groove and abuts against the bottom wall of the first mounting groove, and the other end thereof abuts against the inner shaft. A second mounting groove is provided on the side of the base 17 of the connector close to the second ball, one end of the second elastic member is installed in the second mounting groove and abuts against the bottom wall of the second mounting groove, and the other end thereof abuts against the inner shaft.

[0050] Further, according to actual needs, please combine Figure 8-Figure 11 The above connectors can also be assembled through a bracket N, that is, made into a module structure of the connector, which is convenient for users to use.

[0051] Next, we will introduce the working principle of the connector module structure in combination with the specific device module: Fig.12 and Fig.13 , the contact piece A of the device module 1 presses against the top of the arc of the first ball in the first state, and the first ball then presses against the first inner shaft, and the first inner shaft presses against the first elastic member at the same time, and the first elastic member will be compressed downward after being subjected to force. When the contact piece A of the device module 1 moves horizontally or rotates, the first ball will also rotate at the same time, thereby achieving full contact between the first ball and the contact piece A of the device module 1. After the contact piece A of the device module 1 is no longer pressed against the first ball, the rebound force generated by the first elastic member after being subjected to force pushes the first inner shaft, and then pushes the first ball to return to the first state.

[0052] Please combine Fig.12 and Fig.13 , the contact piece B of the device module 2 presses against the top of the arc of the second ball in the third state, and the second ball then presses against the second inner shaft, and the second inner shaft presses against the second elastic member at the same time, and the second elastic member is compressed downward after being stressed. When the contact piece B of the device module 2 moves horizontally or rotates, the second ball also rotates at the same time, thereby achieving full contact between the second ball and the contact piece B of the device module 2. After the contact piece B of the device module 2 no longer presses against the second ball, the rebound force generated by the second elastic member after being stressed pushes the second inner shaft, and then pushes the second ball to return to the third state.
