Description

Connectors, circuit boards and electronic devices Technical Field

[0001] The embodiments of the present application relate to the field of electronic appliances, and more specifically, to a connector, a circuit board, and an electronic device. Background Art

[0002] An insulation displacement connector (IDC) uses a conductive terminal to pierce the insulation of a wire to achieve an electrical connection. IDCs enable wire-to-board signal transmission. Due to their simple wiring and high efficiency, IDCs are widely used in smart vehicles, smart homes, mechanical engineering, and other industries.

[0003] Traditional IDCs include an observation hole through which operators observe the wires during the wiring process. Specifically, if the operator can see the wires through the hole, they assume they are properly connected; otherwise, they assume they are not. Once the operator determines the wires are properly connected, a crimping and piercing process is performed to establish an electrical connection between the conductive terminals and the wires. However, this method relies on manual visual inspection and is affected by factors such as the light and size of the observation hole, making it difficult to reliably determine whether the IDC wires are properly connected in practice.

[0004] Summary of the Invention

[0005] The embodiments of the present application provide a connector, a circuit board, and an electronic device that can reliably determine whether an IDC wire is properly connected.

[0006] In a first aspect, a connector is provided, comprising: a first connector, the first connector being used to accommodate a wire; a second connector, the second connector comprising a piercing end and a movable portion, the piercing end being used to pierce the wire; when the length of the wire extending into the first connector is less than a first threshold, the movable portion is configured to be in a first position, and the movable portion is configured to block the first connector from being pressed into the second connector in the first position; when the length of the wire extending into the first connector is greater than or equal to the first threshold, the movable portion is configured to be in a second position, and the movable portion is configured to enable the first connector to be pressed into the second connector in the second position.

[0007] The piercing end is specifically used to pierce the wire when the first connector is pressed into the second connector.

[0008] The above-mentioned first position can be understood as the position or position range corresponding to the movable part when the length of the wire extending into the first connecting member is less than the first threshold, and the above-mentioned second position can be understood as the position or position range corresponding to the movable part when the length of the wire extending into the first connecting member is greater than or equal to the first threshold.

[0009] Based on the connector provided in the embodiment of the present application, when the wire is extended into the first connector, the movable portion can be in the second position only when the extension length of the wire is greater than or equal to the first threshold, and the first connector can be pressed into the second connector only when the movable portion is in the second position; otherwise, the first connector will be blocked by the movable portion and cannot be pressed into the second connector.

[0010] Based on this, in an embodiment of the present application, when the first connector is blocked and cannot be pressed into the second connector, it can be considered that the wire is not properly connected (i.e., the length of the wire inserted is less than a first threshold); when the first connector can be pressed into the second connector, it can be considered that the wire is properly connected (i.e., the length of the wire inserted is greater than or equal to the first threshold). This means that in the present application, whether the wire is properly connected can be determined by mechanical linkage, no longer relying on manual visual inspection, and thus can reliably determine whether the wire is properly connected.

[0011] In combination with the first aspect, in certain implementations of the first aspect, the movable portion includes a baffle and a reset unit, the reset unit is fixed to the second connecting member, and the baffle is fixedly connected to the reset unit.

[0012] The reset unit in the embodiment of the present application may include but is not limited to a spring, a spring, or other structures with reset capabilities.

[0013] In an embodiment of the present application, the movable portion may include a baffle and a reset unit, wherein the reset unit enables the baffle to remain in the initial position when it is not subjected to force or the force is removed, so as to prevent the first connector from pressing into the second connector. For example, when the wire is inserted into the first connector, the reset unit can enable the baffle to remain in the initial position when it is not subjected to the pushing force of the wire, so as to prevent the first connector from pressing into the second connector. For another example, when the connector needs to remove the wire for maintenance after a period of use, the reset unit can enable the baffle to return to the initial position again, so that when the wire is reinserted after the maintenance is completed, it is still possible to reliably determine whether the wire is in place. For another example, in scenarios such as transportation before the connector is connected to the wire, the reset unit can enable the baffle to always remain in the initial position.

[0014] In addition, when the wire extends into the first connector, the reset unit can also enable the baffle to gradually move to the second position when it is pushed by the wire, so that the first connector can be pressed into the second connector.

[0015] In combination with the first aspect, in certain implementations of the first aspect, the second connecting member is further provided with a mounting structure of the reset unit, and the reset unit is fixed to the mounting structure.

[0016] It should be understood that the position of the mounting structure can be determined according to the actual position requirement of the reset unit, and the shape of the mounting structure can be determined according to the shape of the reset unit, which is not limited in the embodiment of the present application.

[0017] It should be noted that, in practice, directly securing the reset unit to the second connector may be difficult or costly. For example, if the reset unit itself lacks structural support, direct securing may be difficult. Another example is if the reset unit is located far from a secureable point on the second connector, resulting in a complex and costly securement structure.

[0018] Based on this, in the embodiment of the present application, the second connecting member is further provided with a mounting structure of the reset unit to avoid the situation where the reset unit is difficult to fix or the fixing cost is high, thereby improving the reliability of the fixation of the reset unit.

[0019] In combination with the first aspect, in certain implementations of the first aspect, the reset unit includes a spring, the mounting structure includes a mounting column, the spring is arranged around the mounting column, the central axis of the spring is parallel to the central axis of the mounting column, one end of the spring is fixed to the mounting column, and the other end of the spring is fixed to the baffle.

[0020] In other words, one end of the spring is fixed to the mounting post, which can also be described as the spring being fixed to the second connecting member via the mounting structure.

[0021] In an embodiment of the present application, the reset unit may include a spring, which can keep the baffle in the initial position when not pushed by the wire, and enable the baffle to gradually move to the second position when pushed by the wire.

[0022] In combination with the first aspect, in some implementations of the first aspect, the reset unit includes a spring piece, the spring piece is fixed to the second connecting member, and the baffle is fixedly connected to the spring piece.

[0023] In an embodiment of the present application, the reset unit may include a spring, which can keep the baffle in the initial position when not pushed by the wire, and enable the baffle to gradually move to the second position when pushed by the wire.

[0024] Optionally, the baffle and the spring piece may be fixedly connected by welding or bonding, etc., which is not limited in this application.

[0025] In combination with the first aspect, in certain implementations of the first aspect, the baffle and the spring are an integrated structure.

[0026] That is to say, the baffle and the spring can be integrally formed as a whole. In this case, the baffle and the spring can be collectively referred to as springs, except that a part of the spring has the function of a baffle and the other part has the function of a reset unit.

[0027] In combination with the first aspect, in certain implementations of the first aspect, the first connecting member includes an avoidance structure, which is used to accommodate the movable part. When the movable part is in the second position, the projection of the movable part on the first connecting member is located within the avoidance structure.

[0028] Optionally, when the length of the wire extending into the first connector is greater than or equal to a first threshold, the movable portion is configured to be in the second position, and further includes: when the first connector is pressed into the second connector, the movable portion is accommodated in the avoidance structure.

[0029] Optionally, when the length of the wire extending into the first connector is less than a first threshold and the movable portion is configured to be in the first position, the projection of the movable portion on the first connector is not completely located within the avoidance structure, thereby preventing the first connector from pressing into the second connector.

[0030] In an embodiment of the present application, the first connecting member may further include an avoidance structure. Based on the avoidance structure, when the movable part is pushed by the wire and moves to the corresponding position of the avoidance structure, the movable part can be accommodated in the avoidance structure when the first connecting member is pressed into the second connecting member; conversely, when the movable part is pushed by the wire but has not completely moved to the corresponding position of the avoidance structure, the first connecting member is blocked and cannot be pressed into the second connecting member, so that it is possible to reliably judge whether the wire is connected in place based on whether the first connecting member can be pressed down.

[0031] In combination with the first aspect, in certain implementations of the first aspect, the avoidance structure includes an avoidance hole or an avoidance boss.

[0032] Optionally, in the embodiment of the present application, the avoidance structure includes but is not limited to a avoidance hole or a avoidance boss. The embodiment of the present application does not limit the specific structural form of the avoidance structure on the first connecting member. The avoidance boss can be understood as a raised structure on the first connecting member, and the interior of the raised structure includes a receiving space.

[0033] In a second aspect, a circuit board is provided, comprising a connector as in the first aspect or any possible implementation of the first aspect, wherein the connector is used to achieve electrical connection between a wire and the circuit board.

[0034] In a third aspect, an electronic device is provided, comprising the connector as in the first aspect or any possible implementation of the first aspect; or comprising the circuit board as described in the second aspect.

[0035] Optionally, the electronic device may include, for example, a desktop computer, a laptop computer, a smart phone, a tablet computer, a personal digital assistant (PDA), a wearable device, a smart speaker, a television, a drone, a mobile carrier, a vehicle-mounted device (such as a car computer, a vehicle-mounted computer, etc.) or a robot, etc.

[0036] The mobile carrier may include road vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or entertainment equipment. For example, the mobile carrier may be a vehicle, which is a vehicle in a broad sense and may be a transportation vehicle (such as a commercial vehicle, a passenger car, a motorcycle, an air vehicle, a train, etc.), an industrial vehicle (such as a forklift, a trailer, a tractor, etc.), an engineering vehicle (such as an excavator, a bulldozer, a crane, etc.), agricultural equipment (such as a lawn mower, a harvester, etc.), amusement equipment, a toy vehicle, etc. The embodiments of the present application do not specifically limit the type of vehicle. For another example, the mobile carrier may be a vehicle such as an airplane or a ship. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0045] Before introducing the present application, it should be noted that the connectors described in the embodiments of the present application may also be referred to as insulation displacement connectors (IDCs). It should be understood that an IDC is a piercing connector that utilizes a conductive terminal to pierce the insulation of a wire to achieve an electrical connection between the conductive terminal and the wire. Specifically, the conductive terminal includes a piercing end and a female terminal. The piercing end includes a piercing blade. When the wire is pressed into the piercing blade, the piercing blade pierces the insulation of the outer layer of the wire and directly forms an electrical connection with the wire.

[0046] In practical applications, the connector can be used to achieve wire-to-board signal transmission. Specifically, one end of the wire can be connected to a power source or signal source, and the other end can be connected to the connector, and the electrical connection between the wire and the conductive terminal can be achieved based on the puncture operation of the connector; at the same time, the connector can be electrically connected to the circuit board through the connector seat, wherein the connector seat includes a male terminal seat and a female terminal seat, wherein the male terminal seat can be set on the circuit board, and the female terminal seat is set on the connector and electrically connected to the female terminal of the above-mentioned conductive terminal. After the female terminal seat and the male terminal seat are matched and plugged, the signal of the power source or signal source can be transmitted to the conductive terminal via the wire, and then transmitted to the circuit board via the connector seat, based on this, wire-to-board signal transmission is achieved.

[0047] Figure 1 is a schematic structural diagram of a connector 100 provided in an embodiment of the present application. It should be understood that the various structural components involved in the connector 100 shown in Figure 1 are only examples and may not be limited thereto in actual operation.

[0048] As shown in Figure 1, the connector 100 includes a first connector 10 and a second connector 20. The first connector 10 is used to accommodate a wire 40 (see Figure 2). The second connector 20 includes a piercing end 51 and a movable portion 30, wherein the piercing end 51 is used to pierce the wire 40. When the length of the wire 40 extending into the first connector 10 is less than a first threshold, the movable portion 30 is configured to be in a first position, and the movable portion 30 is configured to block the first connector 10 from being pressed into the second connector 20 in the first position; when the length of the wire 40 extending into the first connector 10 is greater than or equal to the first threshold, the movable portion 30 is configured to be in a second position, and the movable portion 30 is configured to enable the first connector 10 to be pressed into the second connector 20 in the second position.

[0049] The piercing end 51 is specifically used to pierce the wire 40 when the first connecting member 10 is pressed into the second connecting member 20 .

[0050] The first connecting member 10 may include a wire access hole 11 , through which the wire 40 may extend into the first connecting member 10 , as shown in FIG. 2 .

[0051] The second connector 20 may include a conductive terminal 50 and a conductive terminal access hole 21. The conductive terminal 50 may include the piercing end 51 and a female terminal 52 (see FIG4 ). The conductive terminal 50 may be connected to the second connector 20 through the conductive terminal access hole 21 (see FIG3 ).

[0052] The piercing end 51 may include a piercing blade, which can pierce the outer insulation of the wire 40 when the first connector 10 is pressed into the second connector 20 to achieve electrical connection between the conductive terminal 50 and the wire 40.

[0053] The above-mentioned “blocking the first connecting member 10 from being pressed into the second connecting member 20” can also be described as “blocking the first connecting member 10 from being pressed into the second connecting member 20 under the action of force”; the above-mentioned “enabling the first connecting member 10 to be pressed into the second connecting member 20” can also be described as “enabling the first connecting member 10 to be pressed into the second connecting member 20 under the action of force”.

[0054] The above-mentioned first position can be understood as the position or position range corresponding to the movable part 30 when the length of the wire 40 extending into the first connecting member 10 is less than the first threshold, and the above-mentioned second position can be understood as the position or position range corresponding to the movable part 30 when the length of the wire 40 extending into the first connecting member is greater than or equal to the first threshold.

[0055] It should be understood that as the wire 40 is extended, the wire 40 can push the movable portion 30 to move. When the movable portion 30 is gradually pushed to the second position, the first connecting member 10 can be pressed into the second connecting member 20 .

[0056] The embodiment of the present application does not limit the specific position of the movable portion 30 on the second connector 20. It is sufficient as long as the movable portion 30 is moved to the second position by the push of the wire 40, and the piercing end 51 is able to pierce the wire 40 when the first connector 10 is pressed into the second connector 20. In other words, during the insertion of the wire 40, when the wire 40 pushes the movable portion 30 to the second position, the actual position of the wire 40 should correspond to the piercing end 51, so that the piercing end 51 can pierce the wire 40 when the first connector 10 is pressed into the second connector 20. Taking the connector 100 shown in Figure 1 as an example, the movable part 30 should be arranged between the piercing end 51 of the conductive terminal 50 and the female terminal 52. During the connection process, the wire 40 will first extend to the top of the piercing end 51, then extend to the movable part 30 and push the movable part 30 to move until the first connector 10 can be pressed into the second connector 20. Since the top of the piercing end 51 corresponds to a section of the wire 40, when the first connector 10 is pressed into the second connector 20, the piercing end 51 can pierce the wire 40.

[0057] Based on the connector 100 provided in the embodiment of the present application, when the wire 40 extends into the first connector 10, the movable portion 30 can be in the second position only when the extension length of the wire 40 is greater than or equal to the first threshold value, and the first connector 10 can be pressed into the second connector 20 only when the movable portion 30 is in the second position. Otherwise, the first connector 10 will be blocked by the movable portion 30 and cannot be pressed into the second connector 20.

[0058] Based on this, in the embodiment of the present application, when the first connector 10 is blocked and cannot be pressed into the second connector 20, it can be considered that the wire 40 is not properly connected (i.e., the length of the wire 40 is less than the first threshold); when the first connector 10 can be pressed into the second connector 20, it can be considered that the wire 40 is properly connected (i.e., the length of the wire 40 is greater than or equal to the first threshold). This means that in the present application, whether the wire 40 is properly connected can be determined by mechanical linkage (i.e., the linkage between the wire 40 and the movable part 30), no longer relying on manual visual inspection, and thus whether the wire 40 is properly connected can be reliably determined.

[0059] Moreover, the movable portion 30 is an internal structure of the connector 100 , and does not add any additional complex functional modules that need to be shipped separately to the connector 100 , thereby not affecting the packaging and transportation complexity of the connector 100 .

[0060] Optionally, the movable portion 30 may include a baffle 31 and a reset unit, wherein the reset unit is fixed to the second connecting member 20 , and the baffle 31 is fixedly connected to the reset unit.

[0061] The reset unit involved in the embodiment of the present application may include but is not limited to a spring, a spring, or other structures with reset capability. For ease of description, the following focuses on the reset unit as a spring 32 and a spring 36 as an example, but it should be understood that in actual operation, it is not limited to this.

[0062] In an embodiment of the present application, the movable portion 30 may include a baffle 31 and a reset unit, wherein the reset unit enables the baffle 31 to remain in the initial position when no force is applied or the force is released, so as to prevent the first connector 10 from pressing into the second connector 20. For example, when the wire 40 is inserted into the first connector 10, the reset unit can enable the baffle 31 to remain in the initial position when it is not pushed by the wire 40, so as to prevent the first connector 10 from pressing into the second connector 20. For another example, when the connector needs to remove the wire 40 for maintenance after a period of use, the reset unit can enable the baffle 31 to return to the initial position, so that when the wire 40 is reinserted after the maintenance is completed, it is still possible to reliably determine whether the wire 40 is properly connected. For another example, in scenarios such as transportation before the connector is connected to the wire 40, the reset unit 30 can enable the baffle 31 to always remain in the initial position. In addition, when the wire 40 extends into the first connector 10 , the reset unit can also enable the baffle 31 to gradually move to the second position when pushed by the wire, so that the first connector 10 can be pressed into the second connector 20 .

[0063] Optionally, in actual operation, in addition to achieving mechanical linkage through the reset unit, mechanical linkage can also be achieved through other means. For example, the mechanical linkage process can be achieved through a connecting structure such as a hinge structure, an articulation structure, a fastener structure, etc. For example, the movable portion 30 can include a baffle 31 and a fastener structure, and the baffle 31 is fixed to the second connecting member 20 through the fastener structure. The fastener structure is designed to remain in the initial position when there is no thrust. When a thrust is applied or the thrust is greater than a certain value, the baffle 31 can move and perform an evasive movement.

[0064] Optionally, the second connecting member 20 may also be provided with a mounting structure of the reset unit (eg, a mounting post 33 ), and the reset unit is fixed to the mounting structure.

[0065] The reset unit is fixed to the mounting structure, which can also be described as the reset unit being fixed to the second connecting member 20 via the mounting structure.

[0066] It should be noted that, in practice, directly securing the reset unit to the second connector 20 may be difficult or costly. For example, if the reset unit itself lacks structural support, direct securing may be difficult. Another example is if the reset unit is located far from a secureable point on the second connector 20, resulting in a complex and costly securement structure.

[0067] Based on this, in the embodiment of the present application, the second connecting member 20 may also be provided with an installation structure of the reset unit to avoid the situation where the reset unit is difficult to fix or the fixing cost is high, thereby improving the reliability of the fixation of the reset unit.

[0068] It should be understood that the position of the above-mentioned installation structure can be determined according to the actual position requirement of the reset unit, and the shape structure of the installation structure can be determined according to the shape structure of the reset unit, which is not limited in the embodiment of the present application.

[0069] In one implementation, referring to Figures 1 and 3, the reset unit may be a spring 32, and the mounting structure may be a mounting post 33. The spring 32 is disposed around the mounting post 33, with the central axis of the spring 32 parallel to the central axis of the mounting post 33. One end of the spring 32 is fixed to the mounting post 33, and the other end of the spring 32 is fixed to the baffle 31. In this implementation, the spring 32 can maintain the baffle 31 in the initial position when not pushed by the wire 40, and can gradually move the baffle 31 to the second position when pushed by the wire 40.

[0070] Optionally, a mounting hole 34 can be set on the mounting column 33, and one end of the spring 32 can be fixed to the mounting hole 34 of the mounting column 33; similarly, a mounting hole 35 can be set on the baffle 31, and the other end of the spring 32 can be fixed to the mounting hole 35 of the baffle 31.

[0071] It should be understood that the above-mentioned fixing method is only an example. In actual operation, the fixation between the spring 32 and the baffle 31, or the fixation between the spring 32 and the mounting column 33 can also be achieved by other methods. For example, one end of the spring 32 can be fixed to the mounting column 33 by bonding or welding, and the other end of the spring 32 can be fixed to the baffle 31.

[0072] In another implementation, referring to FIG6 , the reset unit may be a spring clip 36, which is fixed to the second connector 20, and the baffle 31 is fixedly connected to the spring clip 36. The spring clip 36 may enable the baffle 31 to remain in the initial position when it is not pushed by the wire 40, and may enable the baffle 31 to gradually move to the second position when it is pushed by the wire 40.

[0073] Optionally, the baffle 31 and the spring 36 can be fixedly connected by welding or bonding, or the baffle 31 and the spring 36 can be an integrated structure, which is not limited in this application. The above-mentioned baffle 31 and the spring 36 are an integrated structure, which can be understood as the baffle 31 and the spring 36 can be integrally formed as a whole. In this case, the baffle 31 and the spring 36 can be collectively referred to as springs (i.e., the movable portion 30 is a spring), except that part of the spring has the function of a baffle, and the other part has the function of a reset unit.

[0074] Optionally, the elastic piece 36 may also be fixed to the second connecting member 20 via a mounting structure.

[0075] Optionally, the first connecting member 10 may further include an avoidance structure, and the avoidance structure is used to accommodate the movable portion 30 .

[0076] Optionally, when the movable portion 30 is in the second position, the projection of the movable portion 30 on the first connector 10 is located within the avoidance structure. Based on this, when the first connector 10 is pressed into the second connector 20, the movable portion 30 can be accommodated in the avoidance structure.

[0077] Optionally, when the movable portion 30 is in the first position, the projection of the movable portion 30 on the first connecting member 10 is not completely located within the avoidance structure, thereby preventing the first connecting member 10 from being pressed into the second connecting member 20 .

[0078] In an embodiment of the present application, the first connector 10 may further include an avoidance structure. Based on the avoidance structure, when the movable part 30 is pushed by the wire 40 and moves to the corresponding position of the avoidance structure, the movable part 30 can be accommodated in the avoidance structure when the first connector 10 is pressed into the second connector 20; conversely, when the movable part 30 is pushed by the wire 40 but has not completely moved to the corresponding position of the avoidance structure, the first connector 10 is blocked and cannot be pressed into the second connector 20, so that it is possible to reliably judge whether the wire 40 is connected in place based on whether the first connector 10 can be pressed down.

[0079] Optionally, in the embodiment of the present application, the avoidance structure may include but is not limited to the avoidance hole 12 or the avoidance boss. The embodiment of the present application does not limit the specific structural form of the avoidance structure on the first connecting member 10. The avoidance boss can be understood as a raised structure on the first connecting member 10, and the interior of the raised structure includes an accommodating space.

[0080] For ease of understanding, the avoidance process of the movable portion 30 will be described below with reference to FIG. 7 , taking the avoidance structure as the avoidance hole 12 on the first connecting member as an example.

[0081] FIG7 is a schematic diagram of the avoidance process of a movable portion provided in an embodiment of the present application. As shown in FIG7 (a), before the wire 40 pushes the baffle 31, the baffle 31 remains in its initial position (i.e., the baffle 31 remains perpendicular to the wire 40). In this case, the first connector 10 is blocked by the baffle 31 and cannot be pressed into the second connector 20. As shown in FIG7 (b), during the process of the wire pushing the baffle 31, when the baffle 31 rotates but does not rotate to the corresponding position of the avoidance hole 12, the first connector 10 is still blocked by the baffle 31 and cannot be pressed into the second connector 20. As shown in FIG7 (c), when the baffle 31 rotates to the corresponding position of the avoidance hole 12, the first connector 10 is no longer blocked by the baffle 31 and can be pressed into the second connector 20.

[0082] Alternatively, instead of providing a relief structure on the first connector 10, the movable portion 30 may be caused to retract in other ways. For example, when the reset unit is a spring, one edge of the spring may be fixed to the bottom of the second connector 20. When pushed by the wire 40, the spring will retract and gradually become parallel to the bottom of the second connector 20, allowing the first connector 10 to be pressed into the second connector 20.

[0083] The above-mentioned first connector 10 can extend into one or more wires 40 at the same time, and this application does not limit this. Correspondingly, the number of conductive terminals 50 and the number of movable parts 30 should be the same as the number of wires 40, and correspond one to one. It should be understood that the positions of the puncture ends 51 of the multiple conductive terminals 50, the multiple movable parts 30 and the multiple avoidance holes 12 shown in the drawings of this application are only examples. In actual operation, the multiple movable parts 30 may not be aligned, as long as it can be ensured that the multiple movable parts 30 are respectively arranged between the puncture ends 51 and the female terminals 52 of the corresponding conductive terminals 50. Correspondingly, the avoidance structures corresponding to the multiple movable parts 30 may also be misaligned, as long as it can be ensured that they correspond to the multiple movable parts 30 after avoidance.

[0084] The connector 100 may further include a snap-fit ​​structure 60, which is used to snap the connector 100 onto the male terminal receptacle on the circuit board when the connector 100 is connected to the male terminal receptacle. The specific location of the snap-fit ​​structure 60 is not limited in this embodiment of the present application.
