Description

Technical Field

[0001] This invention relates to the field of electrical connection components, and more specifically to a harpoon-type plug-in shunt connector. Background Technology

[0002] Most electrical products draw power from plugs and sockets. For example, when lamps are used outdoors, a plug establishes an electrical connection between the socket and the lamp, providing power to the lamp and enabling it to emit light. Nowadays, connectors are more commonly used to establish the connection between the power source and the power-receiving device. The power source connects to the input end of the connector, and the power-receiving device connects to the output end of the connector, providing power to the power-receiving device through the connector.

[0003] In existing technologies, connectors have only one output end, which can only provide power to one power-generating device and cannot achieve dual control output of the same source current or signal.

[0004] Therefore, how to provide a shunt connector with multiple output terminals that can simultaneously supply power to multiple power-generating devices is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To address this issue, the present invention provides a harpoon-type plug-in shunt connector to solve the problem in the prior art where the connector's single output can only provide power to one power-generating device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A harpoon-type plug-in shunt connector includes an input component, an output component, and a connecting terminal. The output component is fixed inside the input component via the connecting terminal. The connecting terminal is harpoon-shaped. The first end of the connecting terminal is fixedly connected inside the input component. The output component has two channels, and the second end of the connecting terminal is respectively inserted into the two channels of the output component.

[0008] Furthermore, it also includes a first metal terminal and a second metal terminal. The first metal terminal is provided in the input terminal component, and the second metal terminal is provided in each of the two channels of the output terminal component. The second end of the connecting terminal is inserted into the second metal terminal.

[0009] Furthermore, both the first metal terminal and the second metal terminal are provided with limiting pieces, and the input terminal component on one side and the output terminal component on both sides are provided with limiting grooves, and the limiting pieces are engaged in the limiting grooves.

[0010] Furthermore, the limiting piece is an outwardly expanding curved elastic piece.

[0011] Furthermore, it also includes a fixing member, which includes a vertical piece and a curved piece. The vertical piece and the curved piece are integrally formed. The bottom end of the output end component is provided with a through groove, and the through groove is connected to the limiting groove. The fixing member passes through the through groove and enters the limiting groove. The vertical piece is placed in the through groove, and the curved piece is placed in the limiting groove. The curved piece is bent toward the limiting piece.

[0012] Furthermore, a shaping groove is provided in the limiting groove, and the outer side of the curved piece abuts against the shaping groove.

[0013] Furthermore, the bent sheet is a bimetallic sheet, and the coefficient of expansion of the outer side of the bent sheet is greater than the coefficient of expansion of the inner side of the bent sheet.

[0014] Furthermore, the fastener includes at least a first use state, and in the first use state, the vertical piece extends out of the through groove, the bending arc of the curved piece is small, and the limiting piece moves within the limiting groove.

[0015] Furthermore, the fastener also includes a second use state, in which the vertical piece is fully inserted into the through groove, and the bending piece has a large curvature, the bending piece abuts against the lower end recess of the limiting piece, and the limiting piece is locked in the limiting groove.

[0016] Furthermore, the fastener also includes a third use state and a fourth use state. In the third use state, the bending piece retracts inward until it is above the limiting piece. In the fourth use state, the bending piece springs back and pushes the limiting piece away from the limiting groove.

[0017] The present invention has the following advantages:

[0018] This application establishes a connection between the input and output components using connecting terminals, which are harpoon-shaped, thereby connecting the two output ports of the output component to the input component. An electrical connection between the power supply and the power-generating device is established through the first metal terminal, the second metal terminal, and the connecting terminals, enabling dual-phase control output of either current or signal from the same source.

[0019] The first and second metal terminals provided in this application are fixed within the input and output components by limiting pieces. A fixing member is established so that when the second end of the connecting terminal is inserted into the output component, the fixing member gradually extends into the limiting groove, increasing the curvature of the bending piece, causing the bending piece to abut against the lower recess of the limiting piece, thereby locking the limiting piece within the limiting groove and fixing the position of the second metal terminal, preventing movement of the second metal terminal from affecting the electrical connection.

[0020] The bending strip provided in this application is a bimetallic strip that can expand when heated. When the circuit heats up too much, the bending strip contracts inward, positioning itself above the limiting strip. After the bending strip stops conducting heat, it springs back and pushes the limiting strip out of the limiting groove, allowing the second metal terminal to detach from the output component. The connector then stops working, protecting the circuit from damage. Attached Figure Description

[0035] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] To address the related technical problems existing in the prior art, this application provides a harpoon-type plug-in shunt connector, aiming to solve the problem of single output in existing connectors and achieve the effect of dual-phase control output of the same source current or signal. For example... Figure 1-3 As shown, the assembly specifically includes an input component 1, an output component 2, and a connection terminal 3. The output component 2 is fixed inside the input component 1 via the connection terminal 3. The connection terminal 3 is harpoon-shaped, with its first end fixedly connected to the input component 1. The output component 2 has two channels, and the second ends of the connection terminal 3 are respectively inserted into the two channels of the output component 2. This application establishes a connection between the input component 1 and the output component 2 through the connection terminal 3. The harpoon-shaped connection terminal 3 establishes a connection between the two output ports of the output component 2 and the input component 1, enabling bidirectional control output of the same source current or signal.

[0037] like Figure 4 and 5 As shown, the input component 1 has a first metal terminal 4, and the two channels of the output component 2 each have a second metal terminal 5. The second end of the connecting terminal 3 is inserted into the second metal terminal 5. The second end of the harpoon-shaped connecting terminal 3 is held tightly within the second metal terminal 5. An electrical connection between the power supply and the power-generating device is established through the first metal terminal 4, the second metal terminal 5, and the connecting terminal 3, enabling dual-phase control output of either current or signal from the same source.

[0038] Both the first metal terminal 4 and the second metal terminal 5 are provided with limiting pieces 6, and both sides of the input terminal component 1 and the output terminal component 2 are provided with limiting grooves 7. The limiting pieces 6 are outwardly expanding curved elastic pieces. Because the limiting pieces 6 are engaged in the limiting grooves 7, the first metal terminal 4 and the second metal terminal 5 are respectively fixed in the input terminal component 1 and the output terminal component 2.

[0039] During installation, the first metal terminal 4 and the second metal terminal 5 are first assembled into the input component 1 and the output component 2, respectively. The first metal terminal 4 is inserted into the input component 1, and the limiting piece 6 on the first metal terminal 4 is pressed into the input component 1 until it reaches the limiting groove 7. Then, the limiting piece 6 springs back to its expanded state and engages in the limiting groove 7. The second metal terminal 4 is inserted into the output component 2 in the same manner. Next, the input component 1 with the connecting terminal 3 is inserted into the output component 2. At this time, the second end of the connecting terminal 3 contacts the second metal terminal 5. Due to friction, the second metal terminal 5 will move within the output component 2, thus affecting the electrical connection.

[0040] A fixing member 8 is provided to secure the position of the second metal terminal 5. For example... Figure 6-9 As shown, the fastener 8 includes a vertical piece 801 and a curved piece 802, which are integrally formed. Figure 10 As shown, the bottom end of the output component 2 has a through groove 9, which communicates with the limiting groove 7. The fixing member 8 passes through the through groove 9 and enters the limiting groove 7. The vertical piece 801 is placed in the through groove 9, and the curved piece 802 is placed in the limiting groove 7. The curved piece 802 is bent towards the limiting piece 6. When the vertical piece 801 is pushed inward, the curved piece 802 abuts against the limiting groove 7, and the curvature of the curved piece 802 gradually increases.

[0041] like Figure 4 As shown, when the input component 1 and the output component 2 are separated, the vertical piece 801 on the output component 2 extends out of the through slot 9. Figure 6 The diagram shows the first usage state of the fastener 8. The vertical piece 801 extends out of the through groove 9, and the bending arc of the bent piece 802 is small. The limiting piece 6 can move within the limiting groove 7. At this time, the second metal terminal 5 can move within the output end component 2 without affecting the installation of the second metal terminal 5.

[0042] When the second end of the connection terminal 3 on the input terminal component 1 is inserted into the output terminal component 2, as Figure 2 As shown, the vertical piece 801 gradually extends into the limiting groove 7 under the pushing force of the input end component 1. Figure 7The second usage state diagram of the fastener 8 shown shows that the vertical piece 801 is fully inserted into the through groove 9, and the curvature of the bent piece 802 is increased, so that the bent piece 802 abuts against the lower end recess of the limiting piece 6. The thrust of the bent piece 802 abuts against the thrust of the connecting terminal 3, thereby making the limiting piece 6 clamped in the limiting groove 7, fixing the position of the second metal terminal 5, and preventing the second metal terminal 5 from moving and affecting the electrical connection.

[0043] A shaping groove 10 is provided in the limiting groove 7, and the outer side of the bending piece 802 abuts against the shaping groove 10. This shaping groove 10 is to accommodate the bending curvature of the bending piece 802, so that the bending piece 802 is shaped in the shaping groove 10 and does not affect the change of the curvature of the bending piece 802.

[0044] The curved sheet 802 is a bimetallic sheet, also known as a thermal bimetallic sheet. The coefficient of thermal expansion of the outer sheet of the curved sheet 802 is greater than that of the inner sheet. The outer sheet of the curved sheet 802 is the active layer, and the inner sheet is the passive layer. Due to the different coefficients of thermal expansion of the constituent layers, when the temperature changes, the deformation of the active layer is greater than that of the passive layer. As a result, the bimetallic sheet as a whole will bend towards the passive layer side, thus changing the curvature of this composite material and causing deformation.

[0045] When input component 1 is connected to output component 2, the bent piece 802 abuts against the limiting piece 6. Through the heat conduction effect of the first metal terminal 4 and the second metal terminal 5, the bent piece 802 is also affected by heat. When the circuit heat is too high, it indicates a fault such as a short circuit. At this time, if... Figure 8 The diagram shows the third usage state of the fastener 8. The bent piece 802 contracts inwards due to heat, positioning itself above the limiting piece 6, until the bent piece 802 is no longer in contact with the limiting piece 6 and is no longer heated. After the heat from the bent piece 802 dissipates, as... Figure 9 The diagram shows the fourth usage state of the fixing member 8. The bending piece 802 springs back and pushes the limiting piece 6 out of the limiting groove 7, allowing the second metal terminal 5 to detach from the output component 2. The connector then ceases operation, protecting the circuit from damage. When the connector is tilted, the second metal terminal 5 can be removed from the output component 2, facilitating inspection, repair, and timely replacement of the metal terminal.

[0046] The usage process of this invention embodiment is as follows:

[0047] When the second end of the connecting terminal 3 on the input component 1 is inserted into the output component 2, the vertical piece 801 gradually extends into the limiting groove 7 under the pushing force of the input component 1. The curvature of the bent piece 802 increases, causing the bent piece 802 to abut against the lower recess of the limiting piece 6. The pushing force of the bent piece 802 counteracts the pushing force of the connecting terminal 3, thereby locking the limiting piece 6 in the limiting groove 7 and fixing the position of the second metal terminal 5. When the circuit heat is too high, the bent piece 802 contracts inward due to heat, positioning itself above the limiting piece 6 until the bent piece 802 no longer contacts the limiting piece 6 and is no longer heated. After the heat of the bent piece 802 dissipates, it springs back and pushes the limiting piece 6 out of the limiting groove 7, allowing the second metal terminal 5 to detach from the output component 2, and the connector ceases to operate.

[0048] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
