Description

Technical Field

[0001] This utility model relates to the field of electrical component access technology, and in particular to circuit protection structures. Background Technology

[0002] In products that commonly involve electrical connections, electrical components are typically connected for functional or protective purposes. However, for product performance testing, different testing environments and requirements impose different requirements on electrical connections. Therefore, in current PCB board structures, a screw hole is usually reserved on the PCB board. Depending on the testing requirements, the screw hole may need to be left unused so that the electrical component is not connected to the circuit, or the screw may be tightened to allow the electrical component to be connected to the circuit.

[0003] This setup makes the PCB manufacturing process more complex, and requires a separate workstation for screw fastening throughout the process, resulting in low production efficiency. Utility Model Content

[0004] The main purpose of this utility model is to propose a circuit protection structure that can connect or disconnect electronic devices to the circuit without screw fastening, with few restrictions, good operability, compatibility with different test environments of the product, and the ability to quickly change the circuit connection status of electronic devices in the product.

[0010] In one embodiment, the first insulating base includes a first base body and a second base body arranged at an angle, the end of the first base body forming the first end, and the end of the second base body forming the second end.

[0011] In one embodiment, the conductive element is movably and adjustably mounted on the second end of the first insulating base, having the conductive position and the disconnected position along its adjustable travel.

[0012] In one embodiment, the conductive element includes:

[0013] The second insulating base has a mounting end opposite to the second end of the first insulating base; and,

[0014] A metal component is mounted on the second insulating base. The metal component has two conductive ends disposed at the mounting end of the second insulating base. When the conductive component is in the conductive position, the two conductive ends are correspondingly connected to two second conductive parts. When the conductive component is in the disconnected position, the two conductive ends are moved away from the corresponding two second conductive parts.

[0015] The second insulating seat is movably and adjustably connected to the first insulating seat in a direction that is close to or far from the first insulating seat.

[0016] In one embodiment, the circuit protection structure includes a snap-fit ​​structure, which includes a snap-fit ​​portion and a mating portion that cooperate with each other. One of the snap-fit ​​portion and the mating portion is disposed on the second insulating base, and the other is disposed on the first insulating base.

[0017] In one embodiment, two sets of fastening slots are provided on opposite sides of the first insulating base, and the two sets of fastening slots are spaced apart along the movement direction of the second insulating base;

[0018] The second insulating base has two mounting arms extending from opposite sides. The two mounting arms are provided with protruding buckles facing each other. The second insulating base is movable such that the protruding buckles of the two mounting arms engage with one of the sets of buckle slots, so that the conductive element is in the conductive position or the disconnected position.

[0019] The snap-fit ​​portion includes the two mounting arms, and the mating portion includes the two sets of snap grooves.

[0020] In one embodiment, the side surface of the first insulating base is provided with a guide protrusion, which is used to engage with a groove on the mating device.

Specifically, when the conductive element is in the on position, the conductive element, the two connecting elements, and the conductive line are connected, allowing the electrical components to be connected to the circuit. When the conductive element is in the off position, the second conductive parts of the two connecting elements do not contact, maintaining the conductive line in an intermittent state between the two conductive pads. Different positions of the conductive element can be selected according to different testing requirements, offering good operability. Throughout the entire process, the two connecting elements and the two conductive pads of the circuit board remain electrically connected. The operator only needs to adjust the conductive element, and this action can be integrated into other workstations after testing. Therefore, electronic components can be connected to or disconnected from the circuit without screw fastening, minimizing limitations, ensuring compatibility with different testing environments, and enabling rapid changes in the circuit connection status of electronic components within the product.

[0042] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] It should be noted that if the embodiments of this utility model involve directional indication, the directional indication is only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0045] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0046] In products that commonly involve electrical connections, electrical components are typically connected for functional or protective purposes. However, for product performance testing, different testing environments and requirements impose different requirements on electrical connections. Therefore, in current PCB board structures, a screw hole is usually reserved on the PCB board. Depending on the testing requirements, the screw hole may need to be left unused so that the electrical component is not connected to the circuit, or the screw may be tightened to allow the electrical component to be connected to the circuit.

[0047] For example, surge protection in automotive OBC / DCDC / PDU / integrated products requires the use of gas discharge tubes. Because these products need to undergo withstand voltage and surge tests, and gas discharge tubes are incompatible with both test conditions, the gas discharge tube must be disconnected for the withstand voltage test before being reconnected. The current design involves a pre-drilled screw hole on the PCB, with the gas discharge tube connected via a grounded metal spring. After the withstand voltage test is completed, the screw is installed to secure the metal spring to the PCB, thus achieving electrical continuity.

[0048] Therefore, this utility model provides a circuit protection structure that does not require additional screws for fastening, thus offering less restriction and better operability; it meets the requirement of product compatibility with different testing environments, improving product compatibility; and it can quickly change the circuit connection status of electronic components within the product, ensuring good operability.

[0049] Please refer to Figures 1 to 2The circuit protection structure 100 includes a circuit board 1 and a switching controller 2. An electrical component 1a is mounted on the circuit board 1. The circuit board 1 is provided with a conductive line connected to the electrical component 1a. The conductive line has two conductive pads located on one side of the circuit board 1. The conductive line is intermittently arranged between the two conductive pads. The switching controller 2 includes two connectors 21 and a connecting component 22. Each connector 21 has a first conductive part 21a and a second conductive part 21b. The two connectors 21 are spaced apart. The first conductive part 21a of the two connectors 21 is connected to the two conductive pads respectively. The connecting component 22 is movably arranged and has a conductive position that connects the second conductive parts 21b of the two connectors 21 and a disconnected position that is separated from at least one of the second conductive parts 21b.

[0050] In this invention, the continuity of the circuit containing the electrical component 1a is controlled by an on / off controller 2. Specifically, when the conductive element 22 is in the on position, the conductive element 22, the two connecting parts 21, and the conductive line are connected, allowing the electrical component 1a to be connected to the circuit. When the conductive element 22 is in the off position, the second conductive parts 21b of the two connecting parts 21 do not contact, maintaining the conductive line in an intermittent state between the two conductive plates. Different positions of the conductive element 22 can be selected according to different testing requirements, offering good operability. Throughout the entire process, the two connecting parts 21 and the two conductive plates of the circuit board 1 remain electrically connected. The operator only needs to adjust the conductive element 22, and this action can be integrated into other workstations after testing. Therefore, electronic components can be connected to or disconnected from the circuit without screw fastening, minimizing limitations, ensuring compatibility with different testing environments, and enabling rapid changes in the circuit connection status of electronic components within the product.

[0051] This invention does not limit the application conditions of the circuit protection structure 100; it can be used in any situation where the circuit state of the electrical component 1a changes. In one embodiment, the conductive line is configured as a surge protection circuit, and the electrical component 1a is configured as a gas discharge tube. Before the withstand voltage test, the gas discharge tube is disconnected from the PE circuit (protective conductor, ground wire) by adjusting the conductive element 22. After the withstand voltage test, no additional components are needed; simply adjusting the conductive element 22 to the conductive position is sufficient to connect the gas discharge tube to the PE circuit. In other embodiments, the electrical component 1a can also be a capacitor or resistor, adapting to circuit connections in other test conditions. This invention will not provide a detailed description of these aspects.

[0052] It should be understood that the connectors 21 and the conductive pads only need to be able to form an electrically conductive structure after being fitted together; the specific structural form is not limited in this application. In some embodiments, each connector 21 is configured as a soldering pin, with the two ends of the soldering pin forming a first conductive portion 21a and a second conductive portion 21b; each conductive pad is configured as a solder pad. In this case, one end of the two soldering pins is soldered and fixed to the two solder pads, and the other end is fitted with the conductive element 22. In other embodiments, the connector 21 can be a metal wire, and the requirements can also be met through a reasonable connection process.

[0053] It should be noted that the conductive element 22 can be entirely made of metal or only partially made of metal, thereby enabling the function of electrical conduction.

[0054] For installation, support, and assembly, the on / off controller 2 includes a first insulating base 23, which has a first end near the circuit board 1 and a second end away from the circuit board 1. Two connectors 21 are mounted on the first insulating base 23, with the first conductive portion 21a of each connector 21 extending and protruding from the first end of the first insulating base 23, and the second conductive portion 21b of each connector 21 extending and protruding from the second end of the first insulating base 23. The first insulating base 23 serves as a support and mounting element, allowing it to be placed on other mating devices connected to the circuit board 1, thereby providing support and fixation for the connectors 21.

[0055] For example, when the circuit protection structure 100 is applied to a connector, the first insulating seat 23 can be fixed to the connector body to keep the position of the connector 21 fixed.

[0056] To ensure proper installation of connector 21, please refer to... Figure 3 Two mounting channels 236 are formed on the first insulating base 23, both of which pass through the first end and the second end of the first insulating base 23. Each connector 21 is disposed in the corresponding mounting channel 236, and the first conductive part 21a and the second conductive part 21b both protrude from the corresponding mounting channel 236. This enables stable installation of the connector 21, and the first conductive part 21a and the second conductive part 21b protruding from the corresponding mounting channel 236 avoids interference from the first insulating base 23 on the conductive fit.

[0057] It should be understood that the shape of the first insulating base 23 is not limited according to different application conditions. For example, the first insulating base 23 can be an elongated structure, with a first end and a second end formed at opposite ends in the vertical direction, in which case the connector 21 is also an elongated structure. Alternatively, the first insulating base 23 can be a block structure, with two adjacent side ends forming a first end and a second end respectively. It should be understood that the connector 21 can be a standard shape or a multi-segment bent structure.

[0058] In an embodiment of this utility model, the first insulating base 23 includes a first base body 231 and a second base body 232 arranged at an angle. The end of the first base body 231 forms a first end, and the end of the second base body 232 forms a second end. That is, the first insulating base 23 is L-shaped. Correspondingly, the shape of the connector 21 is not limited and can also be L-shaped, thereby adapting to different mounting orientations of the circuit board 1 and the mating device. It should be understood that, based on different mounting conditions, the mating device can be a connector body or other male connector structures.

[0059] Based on the above embodiments, when the first insulating base 23 is provided with an installation channel 236 for the connector 21 to be installed, the installation channel 236 needs to pass through the first base body 231 and the second base body 232 at the same time.

[0060] Furthermore, the conductive element 22 can move in a straight line, thereby turning the circuit on and off by moving closer to or away from the two second conductive parts 21b; it can also be rotatable, thereby turning the circuit on and off by rotating to contact or offset from one of the second conductive parts 21b; or it can be a movable state in which the position can be changed by being plugged and unplugged by the operator.

[0061] In this embodiment, the conductive element 22 is movably and adjustably mounted on the second end of the first insulating base 23, and has a conductive position and a disconnected position during its adjustment stroke. Specifically, the conductive element 22 includes a second insulating base 221 and a metal element 222. The second insulating base 221 has a mounting end opposite to the second end of the first insulating base 23; the metal element 222 is mounted on the second insulating base 221 and has two conductive ends disposed on the mounting end of the second insulating base 221. When the conductive element 22 is in the conductive position, the two conductive ends are correspondingly connected to the two second conductive parts 21b. When in the disconnected position, the two conductive ends are moved away from the corresponding two second conductive parts 21b. The second insulating base 221 is movably and adjustably connected to the first insulating base 23 in a direction that is closer to or farther away from the first insulating base 23. The second insulating base 221 serves the function of mounting and connection, while the metal element 222 remains fixed relative to the second insulating base 221, serving the function of conducting the circuit. The conductive element 22 can be an assembly. The setting of the second insulating base 221 makes it easy for the operator to hold or touch the conductive element 22, which can ensure safety.

[0062] It should be understood that the shape of the metal part 222 is not limited in this utility model. It can be a sheet structure with two opposite ends facing the side of the circuit board 1 forming two conductive ends, or it can be a U-shaped structure with two corresponding extended arms forming two conductive ends.

[0063] To achieve the movable engagement of the second insulating seat 221 and the first insulating seat 23, the circuit protection structure 100 includes a snap-fit ​​structure. The snap-fit ​​structure includes a snap-fit ​​portion and a mating portion that cooperate with each other. One of the snap-fit ​​portion and the mating portion is located on the second insulating seat 221, and the other is located on the first insulating seat 23. The snap-fit ​​portion and the mating portion define the relative orientation of the second insulating seat 221 and the first insulating seat 23. This invention does not limit the specific structural form of the snap-fit ​​structure; it can be a snap-fit ​​and a slot, or a flange and a groove.

[0064] In this embodiment, please refer to Figure 3 and Figure 5 The first insulating seat 23 has two sets of latching grooves 233 on opposite sides, and the two sets of latching grooves 233 are spaced apart along the movement direction of the second insulating seat 221. The second insulating seat 221 has two mounting arms 2211 extending from opposite sides, and the two mounting arms 2211 have protruding buckles on their sides facing each other. The second insulating seat 221 is moved so that the protruding buckles of the two mounting arms 2211 engage with one of the sets of latching grooves 233, so that the conductor 22 is in the conducting position or the disconnected position. The engaging part includes two mounting arms 2211, and the mating part includes two sets of latching grooves 233. The mounting arm 2211 and the protruding buckle cooperate to form a barb structure. Initially, the protruding buckle engages with the buckle slot 233 away from the circuit board 1. At this time, the metal part 222 is away from the second guide part 21b, and the conductive part 22 is in the disconnected position. After the corresponding test, the external force pushes the second insulating seat 221 to move the protruding buckle to engage with another buckle slot 233. At this time, the metal part 222 contacts the two second guide parts 21b, and the conductive part 22 is in the conductive position. The structure is simple and easy to operate. It should be understood that the positions of the barb structure and the buckle slot can be interchanged. That is, the barb structure can be set on the first insulating seat 23, and the buckle slot 233 can be set on the second insulating seat 221, which can also achieve the same function.

[0065] In addition, the side surface of the first insulating base 23 is provided with a guide protrusion 234, which is used to mate with the groove on the mating device. This serves as a guide for installation, making it easier for operators to assemble.

[0066] Furthermore, considering the fixed position of the connector 21, a limiting member is provided on the first insulating base 23 to fix the first insulating base 23 to the mating device. The limiting member is used to limit the position of the first insulating base 23 and the mating device, so as to prevent the connector 21 from failing due to shaking after assembly and during testing.

[0067] This utility model does not limit the structural form of the limiting member. For example, the limiting member can be a screw-in member, which screws the first insulating seat 23 onto the mating device. In this embodiment, two oppositely arranged sides of the first insulating seat 23 are each provided with an inclined elastic arm 235. The two elastic arms 235 extend in a direction away from each other and are used to engage with the mating device together. The limiting member includes two elastic arms 235. Specifically, a groove-like structure or a boss structure can be provided on the mating device to engage with the elastic arms 235, which facilitates the installation of the first insulating seat 23 and prevents the first insulating seat 23 from falling off after installation.

[0068] This utility model does not limit the specific form of the conductive element 22. The conductive element 22 can be an assembly. As mentioned above, the conductive element 22 can also be a shorting socket, the metal part of which is used to conduct the second conductive part 21b of the two connecting elements 21. A shorting socket of appropriate size is selected to cooperate with the two connecting elements 21 to achieve the function, and the corresponding mating structure is set on the plastic surface of the shorting socket. The conductive element 22 can also be directly connected to the mating device as a whole and can move relative to the mating device. That is, the conductive element 22 is a structure assembled on the mating device or is built into it and is used for the conduction function. In this case, the installation mating structure between the conductive element 22 and the first insulating seat 23 can be eliminated.

[0069] exist Figure 1 In this embodiment, connector 21 is configured as a soldering pin, conductive element 22 is configured as a shorting nut, and circuit protection structure 100 is applied in the connector. For surge protection, the screw and columnar structure shown in the figure represent the grounding structure of circuit board 1. The first insulating seat 23 is fixed to the connector body 200. During the withstand voltage test, the shorting nut is engaged in the slot 233 away from circuit board 1, disconnecting the gas discharge tube from the PE circuit. After the withstand voltage test, the shorting nut is pressed into the slot 233 near circuit board 1 using external tooling, thus connecting the gas discharge tube to the PE circuit. No additional components are required to connect the gas discharge tube to the PE circuit. The shorting nut pressing method is simple and easy to operate.

[0070] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
