Description

[Technical field]

[0001] The utility model relates to the field of charging and data transmission lines, in particular to a Type-C connector, a connection component, a switching component and a data line. [Background technology]

[0002] At present, the terminal equipment needs to be equipped with a data cable, which can realize the charging of the terminal equipment and the data transmission between other devices. The current terminal equipment usually has an electrical interface, and the plug of the data cable can be plugged into the electrical interface.

[0003] In order to facilitate the connection of the data cable plug to the electrical interface, the prior art provides magnetic components on both the plug and the electrical interface, which is convenient for users to operate in a darker environment (such as at night, in a basement, etc.). However, in the prior art, in order to directly achieve a stable electrical connection between the plug and the electrical interface, a snap-on component such as a hook is provided in the plug. When the plug is inserted into the electrical interface, the plug and the electrical interface are still connected by a snap-on connection, which makes the direct plugging and unplugging force between the electrical interface and the plug too large. On the one hand, it is not convenient to achieve blind plugging. On the other hand, in the process of pulling out the plug, the terminal device is easily moved by the snap-on component, causing the terminal device to fall and be damaged. [Utility Model Content]

[0004] In order to solve the technical problem of excessive insertion and extraction force between the plug and the external charging interface in the prior art, the utility model provides a Type-C connector, a connection component, a switching component and a data cable.

[0005] The solution to the technical problem of the utility model is to provide a Type-c connector, which is magnetically matched with an external female head. A plurality of contact terminals are arranged in the Type-c connector, and a wiring board that matches with the contact terminals is arranged in the female head. It is characterized in that the Type-c connector also includes a positioning component, which defines a receiving cavity for accommodating the contact terminals. When the Type-c connector is magnetically matched with the female head, the positioning component is at least partially located in the female head and the positioning component is not provided with a clamping structure that matches with the female head.

[0006] Furthermore, the positioning assembly is also provided with an opening, the accommodating cavity is connected with the outside through the opening, and along the cross section parallel to the opening direction, the minimum dimension of the accommodating cavity is not less than the maximum dimension of the wiring board in the same direction.

[0007] Furthermore, the positioning assembly includes a positioning shell, and the positioning shell and the female head are clearance-fitted.

[0008] Furthermore, the positioning assembly includes a positioning shell, and the inner wall of the accommodating cavity is formed by the inner wall of the positioning shell.

[0009] Further, the positioning component includes a positioning member and a positioning shell. The positioning members are arranged on opposite sides of the wiring board, and the positioning members are positioned and connected to the positioning shell and / or the wiring board. The inner part of the accommodating cavity is formed by the outer wall of the positioning member and the inner wall of the positioning shell.

[0010] Further, the positioning component further includes a magnetic attraction member. The magnetic attraction member is arranged on the outer periphery of the positioning shell and at least one end of the positioning shell is exposed outside the magnetic attraction member. When the Type-c connector is magnetically engaged with a female head outside through the magnetic attraction member, at least a part of the positioning shell is located inside the female head.

[0011] To further solve the above problems, the present invention further provides a connection component, which includes a Type-c connector as described above, and further includes a female connector arranged on an external device. The Type-c connector is magnetically engaged with the female connector.

[0012] To further solve the above problems, the present invention further provides an adapter component, which includes a Type-c connector as described above, and further includes an adapter. One end of the adapter is defined as an input end, and the other end is defined as an output end. The output end is connected to a female head of an external device to achieve electrical connection or signal connection. The input end is magnetically connected to the Type-c connector to achieve electrical connection or signal connection. When the Type-c connector is magnetically engaged with the adapter, the positioning component is at least partially located inside the input end and the positioning component is not stuck to the input end.

[0013] Further, the force required to pull out the output end from the female head is greater than the force required to pull out the Type-c connector from the input end.

[0014] To further solve the above problems, the present invention further provides a data cable, which includes a Type-c connector as described above, and further includes a cable. The Type-c connector is arranged at least at one end of the cable, and the cable is electrically connected to the contact terminals.

[0015] Compared with the prior art, a Type-c connector, a connection component, an adapter component and a data cable provided by the present utility model have the following advantages:

[0016] 1. In an embodiment of the present utility model, a Type-c connector is magnetically attracted and cooperated with an external female head. A plurality of contact terminals are arranged in the Type-c connector, and a wiring board matched with the contact terminals is arranged in the female head. It is characterized in that the Type-c connector further includes a positioning component, the positioning component defines a receiving cavity for receiving the contact terminals. When the Type-c connector is magnetically attracted and cooperated with the female head, at least a part of the positioning component is located in the female head and no clamping structure for cooperating with the female head is arranged on the positioning component. It can be understood that through the non-clamping setting method, the insertion force required for the Type-c connector to be inserted into the external female head is reduced, so that the effect of blind attraction can be achieved under the action of magnetic attraction between the Type-c connector and the female head. In the case of poor light or when it is inconvenient for the user to insert the Type-c connector into the female head, automatic attraction can be realized and the electrical connection or signal connection between the Type-c connector and the female head can be achieved.

[0017] 2. An opening is further arranged on the positioning component of the Type-c connector provided in the embodiment of the present utility model, and the receiving cavity is communicated with the outside through the opening. Along the cross-section parallel to the direction of the opening, the minimum dimension of the receiving cavity is not less than the maximum dimension of the wiring board in the same direction. It can be understood that in the case of insufficient light, the Type-c connector and the female head can be aligned by magnetic attraction, and the contact terminals are in contact connection with the pins in the female head to achieve electrical transmission or signal transmission. When the Type-c connector is cooperated with the female head, other components in the Type-c connector except the contact terminals are not clamped or abutted against the female head, thereby reducing the resistance of the Type-c connector inserted into the female head. During the blind insertion process, automatic alignment and insertion into the female head can be achieved only by the magnetic force generated between the magnetic attraction member and the female head. At the same time, it also avoids the situation that due to the large insertion and extraction force between the Type-c connector and the female head, when the user accidentally stumbles over the data cable, it is easier to pull the terminal device and cause it to fall and damage the device.

[0018] 3. The positioning component of the Type-c connector provided in the embodiment of the present utility model includes a positioning shell, and the positioning shell and the female head are in clearance fit. It can be understood that compared with the transition fit or interference fit, the friction force between the positioning shell and the female head can be reduced by the clearance fit method, further reducing the resistance required for the Type-c connector to be inserted into the female head, and thus being beneficial to achieving the technical effect of blind insertion.

[0019] 4. The present utility model further provides a connection component, which includes a Type-c connector and a female connector arranged on an external device. The Type-c connector is magnetically attracted and cooperated with the female connector, and has the same beneficial effects as a Type-c connector, which will not be elaborated here.

[0020] 5. The implementation of the present utility model also provides an adapter assembly, which includes a Type-C connector and an adapter. One end of the adapter is defined as the input end, and the other end is the output end. The output end is connected to the female head of an external device to achieve electrical connection or signal connection. The input end is magnetically connected to the Type-C connector to achieve electrical connection or signal connection. When the Type-C connector is magnetically engaged with the adapter, the positioning component is at least partially located inside the input end and is not clamped with the input end. It should be noted that in the prior art, the female head in the external device does not have a magnetic attraction function. Therefore, through such a setting, an adapter is installed on the external device, so that the Type-C connector can be blindly engaged with the adapter through magnetic attraction to achieve electrical connection or signal connection with the external device.

[0021] 6. The data cable provided by the embodiment of the present utility model includes the above-mentioned Type-C connector and also includes a cable. The Type-C connector is at least disposed at one end of the cable, and the cable is electrically connected to the contact terminal. Through such a design, it is beneficial to blindly insert the Type-C connector onto the female head by the action of magnetic attraction when using the data cable, and then achieve electrical connection or signal connection with an external device through the data cable.

Detailed implementation manners

[0038] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the attached drawings and implementation examples. It should be understood that the specific implementation examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0039] It should be noted that the terms "first" and "second" etc. in the description and claims of the present utility model are used to distinguish different objects, rather than to describe a specific order.

[0040] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

These terms are mainly used to better describe the present utility model and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0042] Moreover, in addition to being used to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present utility model can be understood according to specific circumstances.

[0043] In addition, terms such as "installed", "set", "provided with", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, elements or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0044] Please refer to Figure 1 、 Figure 2 and Figure 3 , the first embodiment of the present utility model provides a Type-c connector 1, which is magnetically coupled with an external female head 2 to achieve electrical connection or signal connection. A plurality of contact terminals 11 are arranged in the Type-c connector 1, and a wiring board 21 adapted to the contact terminals 11 is arranged in the female head 2. Specifically, there are multiple contact terminals 11, and pins adapted to the contact terminals 11 are arranged on the wiring board 21 in the female head 2. When the contact terminals 11 are connected to the wiring board 21, electrical connection or signal transmission is achieved. The Type-c connector 1 and the female head 2 are connected by a magnetic connection method, which is convenient for positioning based on the magnetic attraction in a poorly lit environment, so that the Type-c connector 1 is inserted into the female head 2.

[0045] Furthermore, the Type-c connector 1 further includes a positioning component 12. The positioning component 12 defines an accommodation cavity 121 for accommodating the contact terminals 11. When the Type-c connector 1 is magnetically coupled with the female head 2, at least part of the positioning component 12 is located in the female head 2 and no clamping structure for cooperating with the female head 2 is provided on the positioning component 12.

[0046] It should be noted that the positioning component 12 plays a positioning role, enabling the contact terminals 11 to correspond one by one with the thimbles on the wiring board 21, thus avoiding dislocation.

[0047] It should be noted that in the prior art, in order to achieve stable electrical connection or signal transmission after the Type-c connector 1 is inserted into the female head 2, a clamping component is provided to enable the Type-c connector 1 to be clamped with the female head 2 after being inserted into the female head 2, and it is not easy to fall off from the female head 2. Specifically, a groove is provided on the wiring board 21 of the female head 2, and a hook is provided on the Type-c connector 1. When the Type-c connector 1 is inserted into the female head 2, the hook is embedded in the groove to achieve clamping, so that the Type-c connector 1 is not easy to be pulled out from the female head 2. It can be understood that through such a setting, during the process of inserting the Type-c connector 1 into the female head 2, the existence of the hook will increase the insertion force required during the insertion process of the Type-c connector 1. When the magnetic suction force between the Type-c connector 1 and the female head 2 is small, it will cause the user to provide a certain force during the insertion process, and blind suction cannot be achieved, so it is not suitable for use in an environment with poor light; however, if the magnetic suction force between the Type-c connector 1 and the female head 2 is increased, during the process of pulling out the Type-c connector 1 from the female head 2, due to the clamping force between the hook and the groove, at least the clamping force and the magnetic suction force need to be overcome during the pulling out process, so that the user needs to spend more force to pull out, which is not convenient for use.

[0048] Therefore, in this embodiment, the positioning component 12 is not provided with a clamping structure that cooperates with the female head 2. When the Type-c connector 1 and the female head 2 are magnetically attracted and cooperated, the positioning component 12 is not clamped with the female head 2. Through such a setting, the insertion force required during insertion is reduced, and the effect of blind suction can be achieved only by the magnetic suction force between the Type-c connector 1 and the female head 2. Especially in an environment with poor light, under the magnetic suction effect, the Type-c connector 1 can be automatically adsorbed and inserted when approaching the female head 2; during use, due to the existence of the magnetic suction force, the Type-c connector 1 and the female head 2 can achieve stable electrical connection or signal connection; when pulling out the Type-c connector 1, the required pulling force only needs to be greater than the magnetic suction force between the Type-c connector 1 and the female head 2, so as to avoid the problem that it is not easy to pull out due to the existence of the clamping force.

[0049] Furthermore, the positioning component 12 includes a positioning shell 122, and the positioning shell 122 is in clearance fit with the female head 2.

[0050] It should be noted that compared with interference fit and transition fit, clearance fit can avoid the outer periphery of the positioning shell 122 abutting against the inside of the female head 2, thereby increasing the insertion force required for the Type-c connector 1 to be inserted into the female head 2.

[0051] Further, please refer to Figure 2 、 Figure 4 and Figure 5 . The positioning component 12 is further provided with an opening, and the accommodating cavity 121 communicates with the outside through the opening. Along the cross-section parallel to the switching direction, the minimum dimension of the accommodating cavity 121 is not less than the maximum dimension of the wiring board 21 in the same direction.

[0052] It should be noted that when the Type-c connector 1 is inserted into the female head 2, the wiring board 21 enters the accommodating cavity 121 from the opening, and both sides of the wiring board 21 are respectively attached to the contact terminals 11 to achieve electrical connection and signal connection. Along the interface parallel to the opening direction, the maximum width Q and maximum thickness of the wiring board 21, as well as the minimum width L1 and minimum height H1 of the accommodating cavity 121, can be obtained. Since the minimum width L1 of the accommodating cavity 121 is not less than the maximum width Q of the wiring board 21, and the minimum height H1 of the accommodating cavity 121 is not less than the maximum thickness of the wiring board 21, when the Type-c connector 1 is mated with the female head 2, only the contact terminals 11 in the accommodating cavity 121 are in contact with the wiring board 21, and the other components of the Type-c connector 1 do not cooperate or connect with the wiring board 21, thereby reducing the resistance when the Type-c connector 1 is inserted into the female head 2. During the blind insertion process, only relying on the magnetic attraction force generated between the Type-c connector 1 and the female head 2 can achieve automatic alignment and automatic adsorption into the female head 2, and electrical connection or signal connection is achieved through the contact terminals 11 and the female head 2, and the user does not need to consume extra force for plugging and unplugging and alignment. Secondly, when the Type-c connector 1 is mated with the female head 2, the Type-c connector 1 can also be easily pulled out, avoiding a large insertion and extraction force between the Type-c connector 1 and the female head 2. When the user accidentally stumbles over the wire connected to the Type-c connector 1, it is easier to pull the terminal device connected to the female head 2 and cause it to fall, which is more likely to cause damage to the female head 2 or the Type-c connector 1, or pose a safety hazard.

[0053] Furthermore, the positioning component 12 includes a positioning shell 122, the contact terminal 11 is fixedly connected to the positioning shell 122, and the inner wall of the accommodating cavity 121 is formed by the inner wall of the positioning shell 122.

[0054] It should be noted that the positioning shell 122 surrounds to form a receiving cavity 121, and only the contact terminal 11 is included in the receiving cavity 121. Therefore, the minimum width of the receiving cavity 121 is L1, and the minimum height is H1. When ensuring that the minimum width L1 of the receiving cavity 121 is not less than the maximum width Q of the wiring board 21 and the minimum height H1 of the receiving cavity 121 is not less than the maximum thickness of the wiring board 21, the insertion and extraction force between the Type-c connector 1 and the female head 2 is reduced to the greatest extent. It can be understood that when inserting and extracting the Type-c connector 1, only the friction force between the contact terminal 11 and the wiring board 21 needs to be overcome, and thus blind insertion can be achieved by relying on the magnetic force between the Type-c connector 1 and the female head 2.

[0055] Further, please refer to Figure 2 、 Figure 6 and Figure 7 , in some embodiments, the positioning assembly 12 includes a positioning shell 122 and a positioning member 123. The positioning shell 122 surrounds to form a cavity. The contact terminal 11 is fixedly connected to the positioning shell 122. The positioning member 123 is arranged on opposite sides of the contact terminal 11, and the positioning member 123 is positioned and connected to the positioning shell 122 and / or the wiring board 21. The inner wall of the receiving cavity 121 is composed of the outer wall of the positioning member 123 and the inside of the positioning shell 122.

[0056] It should be noted that both the positioning member 123 and the positioning shell 122 play a positioning role. When the Type-c connector 1 is inserted into the female head 2, under the action of the positioning shell 122 and the positioning member 123, the contact terminal 11 is aligned with the top pin on the wiring board 21 to avoid misalignment. Specifically, the positioning member 123 can be fixedly connected to the wiring board 21 such as by welding or bonding, or detachably connected such as by snap connection or screw connection, and can also be fixedly connected or detachably connected to the positioning shell 122. This embodiment does not make specific limitations. As a preferred implementation, the distance between opposite sides of the two positioning members 123 is slightly greater than the maximum distance between opposite sides of the wiring board 21 in the same direction, which can play a role in correcting the insertion direction when the Type-c connector 1 is inserted into the female head 2.

[0057] It should be noted that if the positioning component 12 includes the positioning member 123, at this time, the accommodation cavity 121 is formed by the outer wall of the positioning member 123 and the inner wall of the positioning shell 122. The minimum width of the accommodation cavity 121 is the distance L2 between two relatively arranged positioning members 123, and the minimum height of the accommodation cavity 121 is the distance H2 between the two opposite inner wall surfaces of the positioning shell 122. Since the minimum width L2 of the accommodation cavity 121 is not less than the maximum width Q of the wiring board 21, and the minimum height H2 of the accommodation cavity 121 is not less than the maximum thickness of the wiring board 21, during the process of the Type-c connector 1 being inserted into the female head 2 in parallel, the positioning member 123 does not abut against the wiring board 21 to generate frictional force, so that blind insertion can be achieved only by the magnetic attraction force between the Type-c connector 1 and the female head 2. It should be noted that in the prior art, a hook is provided in the Type-c connector 1, that is, a protrusion is provided on the positioning member 123 in this embodiment, and a notch 211 is provided on the wiring board 21. During the process of the Type-c connector 1 being inserted into the female head 2, the hook undergoes a certain deformation and finally the protrusion is caught in the notch 211, so that the Type-c connector 1 needs to spend a certain amount of effort to be inserted into the female head 2 and is not easily pulled out of the female head 2, that is, the technical effect of automatic insertion and blind insertion cannot be achieved only by the magnetic attraction force between the Type-c connector 1 and the female head 2. Therefore, the present utility model makes an improvement on the Type-c connector 1, sets the hook in the prior art as the positioning member 123, so that there is no clamping force between the Type-c connector 1 and the female head 2, reduces the resistance when the Type-c connector 1 is inserted into the female head 2 or pulled out of the female head 2, and the user does not need to consume extra force for plugging and unplugging and alignment. The stable electrical connection and signal connection between the Type-c connector 1 and the female head 2 can be satisfied only by the magnetic action between the Type-c connector 1 and the female head 2. At the same time, when an external force acts, when the external force is greater than the magnetic attraction force between the Type-c connector 1 and the female head 2, the Type-c connector 1 can be pulled out of the female head 2, avoiding the problem that when the user accidentally trips over the wire connected to the Type-c connector 1, it is easier to pull the terminal device connected to the female head 2 and cause it to fall, which is more likely to cause damage to the female head 2 or the Type-c connector 1, or pose a safety hazard.

[0058] Exemplarily, in the prior art, the insertion force required for the Type-c connector 1 to be inserted into the female head 2 is 10-15N. In the present application, since the Type-c connector 1 and the female head 2 are not clamped, the insertion force required for the Type-c connector 1 to be inserted into the female head 2 is within 5N, and the magnetic attraction force between the Type-c connector 1 and the female head 2 is preferably 10-25N. The difference between the magnetic attraction force and the insertion force is within the range of 5-20N, so that the technical effect of blind suction can be achieved. The force required for the Type-c connector 1 to be pulled out of the female head 2 is within the range of 15-30N, which is also convenient for the user to pull out.

[0059] Further, please refer to Figure 2 , Figure 3 and Figure 8 , the positioning component 12 further includes a magnetic attracting member 124. The magnetic attracting member 124 is disposed on the outer periphery of the positioning shell 122 and at least one end of the positioning shell 122 is exposed outside the magnetic attracting member 124. When the Type-c connector 1 is magnetically engaged with the external female head 2 through the magnetic attracting member 124, at least a part of the positioning shell 122 is located inside the female head 2.

[0060] It should be noted that the magnetic attracting member 124 is made of a magnetic material and can maintain a permanent magnetism after magnetization. A connecting member 22 that can be magnetically attracted to the magnetic attracting member 124 is provided inside the female head 2. In the case of insufficient light, the Type-c connector 1 can be adsorbed to the female head 2 through the magnetic attracting member 124 and the connecting member 22. Specifically, the magnetic attracting member 124 is disposed around the positioning shell 122, which is convenient for positioning the positioning shell 122, so as to achieve blind plugging.

[0061] In some embodiments, a magnet is provided inside the female head 2, and the magnetic attracting member 124 is a metal member that can be magnetically attracted by the magnet. When the Type-c connector 1 approaches the female head 2, the magnet attracts the magnetic attracting member 124, so that the Type-c connector 1 is connected to the female head 2.

[0062] Further, the positioning shell 122 has opposite two ends. One end defined for cooperating with the female head 2 is a contact end 1221, and the other end is a fixed end 1222. The contact end 1221 is exposed outside the magnetic attracting member 124. A circuit board 13 electrically connected to the contact terminal 11 is provided on a side of the fixed end 1222 away from the contact end 1221.

[0063] It should be noted that the magnetic attracting member 124 is sleeved on the outer periphery of the fixed end 1222, and at least a part of the contact end 1221 is exposed outside the magnetic attracting member 124. When the Type-c connector 1 cooperates with the female head 2, a part of the contact end 1221 is located inside the female head 2.

[0064] In this embodiment, the inner diameter of the fixed end 1222 is larger than the inner diameter of the contact end 1221, and the outer diameter of the fixed end 1222 is also correspondingly larger than the outer diameter of the contact end 1221. Through such a setting, it is beneficial to connect the circuit board 13 to the contact terminal 11. At the same time, at least a part of the circuit board 13 is located inside the contact end 1221, so as to protect the connection part of the circuit board 13 and the contact terminal 11 through the contact end 1221.

[0065] Further, a first protective shell 14 connected to the fixed end 1222 is provided on the outer periphery of the circuit board 13, and the first protective shell 14 at least partially covers the circuit board 13.

[0066] It should be noted that the first protective shell and the fixed end 1222 can be snap-connected or fixedly connected. The magnetic member 124 is disposed on the outer periphery of the first protective shell away from the fixed end 1222. Specifically, the first protective shell 14 is made of a metal material, which mainly plays a role in support and protection. At the same time, it can also prevent the circuit board 13 from being affected by electromagnetic interference in the external environment, reduce the impact of external electromagnetic radiation on the circuit board 13, and improve the reliability and stability of the Type-c connector 1 during data transmission.

[0067] Furthermore, the magnetic member 124 includes an extension portion 1241 and a fixing portion 1242 connected to the extension portion 1241. The extension portion 1241 is disposed on the outer periphery of the contact end 1221, and the fixing portion 1242 is sleeved on the outer periphery of the first protective shell 14.

[0068] It should be noted that the extension portion 1241 and the fixing portion 1242 can be separately manufactured and then fixedly connected by means such as bonding, or they can be integrally formed. This embodiment does not make specific limitations.

[0069] It should be noted that in this embodiment, since the inner diameter of the fixing portion 1242 is larger than the inner diameter of the extension portion 1241, it is convenient to insert the magnetic member 124 from the contact end 1221 onto the outer periphery of the positioning shell 122, so that the fixing portion 1242 is connected to the first protective shell 14 and the extension portion 1241 is connected to the contact end 1221. At the same time, the extension portion 1241 has a larger surface area than the fixing portion 1242, which is convenient for magnetically coupling the Type-c connector 1 with the female head 2.

[0070] It should be noted that the fixing portion 1242 is wrapped around the outer periphery of the first protective shell 14, which can further provide support and protect the circuit board 13 on the inner wall.

[0071] Furthermore, the Type-c connector 1 further includes a second protective shell 15, and the second protective shell 15 completely covers the magnetic member 124.

[0072] It can be understood that the second protective shell 15 can be made of plastics such as polycarbonate, acrylate, polyurethane, etc., which plays a role in protecting the magnetic member 124 and preventing the magnetic member 124 from being damaged or oxidized during use, resulting in a decrease or failure of the magnetic attraction.

[0073] Furthermore, the Type-c connector 1 further includes an insulating member 16. The insulating member 16 is located on the side of the fixing portion 1242 away from the extension portion 1241, and a part of the insulating member 16 is located inside the second protective shell 15.

[0074] It should be noted that one end of the insulating member 16 is located inside the second protective shell 15 and is in contact with the magnetic member 124, and the other end is located outside the second protective shell 15. Specifically, the insulating member 16 can be made of flexible materials such as rubber and silica gel, which play the roles of insulation and reinforcement and can buffer when subjected to external forces. During the production process, after installing the circuit board 13, the positioning shell 122, the first protective shell 14, the magnetic member 124, and the insulating member 16, the second protective shell 15 can be fixedly connected to the magnetic member 124 and the insulating member 16 by bonding or injection molding, etc., to prevent them from falling off during use, thereby extending the service life of the device.

[0075] In some embodiments, the insulating member 16 and the second protective shell 15 are made of the same material. Specifically, after installing the circuit board 13, the positioning shell 122, the first protective shell 14, and the magnetic member 124, they are placed in an injection mold to integrally form the insulating member 16 and the second protective shell 15, so that the second protective shell 15 and the insulating member 16 are fixedly arranged on the outer periphery of the magnetic member 124.

[0076] It can be understood that through the Type-c connector 1 provided in this embodiment, in an environment with weak light, the Type-c connector 1 can be aligned with the female head 2 and automatically adsorbed through the magnetic member 124, so that the positioning shell 122 is inserted into the female head 2 under the action of magnetic force to achieve data transmission or electrical connection. Since there is no clamping or abutting between the positioning shell 122 and the female head 2, the resistance of the Type-c connector 1 inserted into the female head 2 is reduced. During the process of inserting the Type-c connector 1 into the female head 2, the positioning shell 122 can be inserted only by the magnetic force of the magnetic member 124, thus solving the technical problem that the plug and the external charging interface in the prior art cannot achieve blind insertion.

[0077] Please refer to Figure 9 In the second embodiment of the present invention, a connection assembly 3 is provided, which includes the Type-c connector 1 provided in the embodiment, and further includes a female connector 31 provided on an external device, and the Type-c connector 1 is magnetically matched with the female connector 31.

[0078] It should be noted that the female connector 31 can be provided on external devices such as tablet computers, mobile phones, VR glasses, AR glasses, etc., and this embodiment does not make specific limitations. Among them, the Type-c connector 1 is magnetically connected to the female connector 31, and the positioning assembly 12 in the Type-c connector 1 is not clamped to the female connector 31.

[0079] A connection assembly 3 has the same beneficial effects as the Type-c connector 1 provided in the first embodiment, and this embodiment will not be elaborated.

[0080] Please refer to Figure 2 and Figure 10, the third embodiment of the present utility model provides an adapter assembly 4, which includes the Type-c connector 1 provided in the first embodiment, and further includes an adapter 41. One end of the adapter 41 is defined as an input end 411, and the other end is defined as an output end 412. The output end 412 is connected to the female head 2 of the external device to achieve electrical connection or signal connection. The input end 411 is magnetically connected to the Type-c connector 1 to achieve electrical connection or signal connection. When the Type-c connector 1 is magnetically engaged with the adapter 41, the positioning component 12 is at least partially located inside the input end 411 and the positioning component 12 is not clamped with the input end 411.

[0081] It should be noted that in the prior art, the female head 2 in the external device does not have a magnetic attraction function. Therefore, in order to facilitate use in environments with weak light, etc., this embodiment provides an adapter 41. The output end 412 of the adapter 41 is partially located inside the female head 2 and is adapted to the female head 2 to achieve electrical connection or signal connection. The input end 411 of the adapter 41 can be magnetically engaged with the Type-c connector 1 and achieve electrical connection or signal connection with the Type-c connector 1. Through such a setting, the adapter 41 is installed on the external device, so that the Type-c connector 1 can be blindly attracted to cooperate with the adapter 41 to further achieve electrical connection or signal connection with the external device.

[0082] Furthermore, the force required to pull out the output end 412 from the female head 2 is greater than the force required to pull out the Type-c connector 1 from the input end 411.

[0083] It should be noted that there is no clamping between the Type-c connector 1 and the input end 411 in this application, which greatly reduces the force required to pull out the Type-c connector 1 from the input end 411. Since the female head 2 is a conventional setting, there is a clamping between the output end 412 of the adapter 41 and the female head 2. Therefore, the clamping force between the output end 412 and the female head 2 needs to be greater than the force required to pull out the Type-c connector 1 from the input end 411, so as to prevent the adapter 41 from falling off the external device when the Type-c connector 1 is pulled out during use.

[0084] Please refer to Figure 11 , the fourth embodiment of the present utility model provides a data cable 5, which includes the Type-c connector 1 provided in the first embodiment above, and further includes a cable 51. The Type-c connector 1 is at least provided at one end of the cable 51, and the cable 51 is electrically connected to the contact terminal 11.

[0085] It should be noted that the data cable 5 provided in this embodiment can be used as a charging cable and / or a data transmission cable, and the Type-c connector 1 is used as a male head. Specifically, one end of the cable 51 is connected to the Type-c connector 1, and the other end can be connected to other connectors such as mini, micro, Lightning, and Type-c USB connectors, or both ends can be connected to the Type-c connector 1.

[0086] It should be noted that when both ends of the cable 51 are connected to the Type-c connector 1, both ends of the data cable 5 are used as male plugs, which is not specifically limited in this embodiment.

[0087] Compared with the prior art, the Type-C connector, connection assembly, adapter assembly and data cable provided by the utility model have the following advantages:

[0088] 1. The embodiment of the utility model provides a Type-c connector that is magnetically matched with an external female head. A plurality of contact terminals are arranged in the Type-c connector, and a wiring board that matches the contact terminals is arranged in the female head. The characteristic is that the Type-c connector also includes a positioning component, and the positioning component defines a receiving cavity for accommodating the contact terminals. When the Type-c connector is magnetically matched with the female head, the positioning component is at least partially located in the female head and the positioning component is not provided with a clamping structure that matches with the female head. It can be understood that the insertion force required for the Type-c connector to be inserted into the external female head is reduced by the non-clamping setting mode, so that the blind suction effect is achieved under the action of the magnetic attraction between the Type-c connector and the female head. In the case of poor light or when it is inconvenient for the user to insert the Type-c connector into the female head, automatic adsorption can be achieved and the electrical connection or signal connection between the Type-c connector and the female head can be achieved.

[0089] 2. A positioning component of a Type-c connector provided by an embodiment of the utility model is also provided with an opening, and the accommodating cavity is connected to the outside through the opening, and along the cross section parallel to the direction of the opening, the minimum size of the accommodating cavity is not less than the maximum size of the wiring board in the same direction. It can be understood that in the case of insufficient light, the Type-c connector and the female head can be aligned by magnetic attraction, and the contact terminal is in contact with the pin in the female head to achieve electrical transmission or signal transmission. When the Type-c connector is matched with the female head, other components other than the contact terminal in the Type-c connector are not connected or abutted with the female head, thereby reducing the resistance of the Type-c connector to be inserted into the female head. In the blind insertion process, the magnetic force generated between the magnetic attraction component and the female head can achieve automatic alignment and insertion into the female head, and at the same time, it also avoids the large plug-in and pull-out force between the Type-c connector and the female head, which makes it easier for the user to pull the terminal device and cause it to fall when accidentally tripping over the data cable, causing damage to the device.

[0090] 3. A positioning component of a Type-c connector provided in an embodiment of the utility model includes a positioning shell, and the positioning shell and the female head are clearance fit. It can be understood that compared with transition fit or interference fit, the friction between the positioning shell and the female head can be reduced by the clearance fit, and the resistance required for the Type-c connector to be inserted into the female head is further reduced, which is conducive to achieving the technical effect of blind insertion.

[0091] 4. The implementation of the utility model also provides a connection component, including a Type-c connector and a female connector arranged on an external device. The Type-c connector and the female connector are magnetically matched and have the same beneficial effects as a Type-c connector, which will not be repeated here.

[0092] 5. The implementation of the utility model also provides an adapter component including a Type-c connector and an adapter, defining one end of the adapter as an input end and the other end as an output end, the output end is connected to the female head of an external device to achieve electrical connection or signal connection, and the input end is magnetically connected to the Type-c connector to achieve electrical connection or signal connection. When the Type-c connector and the adapter are magnetically matched, the positioning component is at least partially located in the input end and the positioning component is not stuck with the input end; it should be noted that in the prior art, the female head in the external device does not have a magnetic attraction function. Therefore, through such a setting, the adapter is installed on the external device, so that the Type-c connector can be matched with the adapter through blind suction to achieve electrical connection or signal connection with the external device.

[0093] 6. The data cable provided by the embodiment of the utility model includes the above-mentioned Type-c connector and also includes a cable. The Type-c connector is arranged at least at one end of the cable, and the cable is electrically connected to the contact terminal. Through such a design, it is convenient to blindly plug the Type-c connector into the female head through the effect of magnetic attraction when using the data cable, and then realize electrical connection or signal connection with an external device through the data cable.

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
