Description
Technical Field
[0001] The present application relates to the technical field of electronic components, and in particular to a connection terminal that is easy to detect. Background Art
[0002] Terminal blocks are key components for connecting wires in circuits. As electrical systems become increasingly complex, the need for testing them is also growing. Traditional terminal block testing typically requires disassembling some connections or using specialized testing tools, which is cumbersome and inefficient.
[0003] Currently available terminal blocks on the market typically only have wiring holes for connecting wires. During testing, the terminal blocks need to be disconnected, making the operation complex and time-consuming. This prevents online real-time testing. Furthermore, repeated disassembly and assembly can affect the terminal blocks' lifespan and stability, potentially damaging them and hindering frequent testing. Summary of the Invention
[0004] In order to improve the above-mentioned problem, the present application provides a connection terminal that is easy to detect.
[0005] The present application provides a terminal block that is easy to detect and adopts the following technical solution:
[0006] A terminal block that is easy to detect, comprising a shell, a power socket, a conductive sheet, an elastic clip and a control button; the shell is connected to the power socket and covers the power socket; a test hole for power connection testing is provided on the shell; the conductive sheet is installed on the power socket and is located in the shell, the conductive sheet is connected to a bent portion, and the bent portion is located next to the test hole; the elastic clip is located in the shell and extends into the test hole to be connected to the bent portion; the control button is slidably connected to the shell and contacts the elastic clip.
[0007] By adopting the above technical solution, when testing is required, the test wire is inserted into the test hole and connected to the bent part of the conductive sheet. There is no need to disassemble the shell for testing, so as to achieve the effect of convenient detection of the terminal. Press the control button, and the control button presses the elastic clamping piece. The elastic clamping piece presses the bent part to the test wire, fixes the position of the wire, and performs power connection testing to ensure the accuracy of the test.
[0008] Optionally, the shell is further provided with two electrical ports for connecting the positive and negative poles of the wires, both of which are provided with the control button, and a plurality of elastic clips are provided, and the two ends of a single elastic clip are respectively located below the two electrical ports.
[0009] By adopting the above technical solution, the two electrical ports are used to connect and fix the wires when testing is not required. The elastic clip is pressed downward by pressing the button to separate the elastic clip from the bent part. The wire is then inserted from the electrical port and passed through between the elastic clip and the bent part to the conductive sheet to perform normal power connection work of the terminal. After releasing the button, the elastic clip rebounds, thereby clamping the wire between the elastic clip and the bent part, ensuring that the wire connection is stable during normal operation.
[0010] Optionally, a plurality of wire anti-slip grooves are formed at one end of the bending portion close to the elastic clip, and the elastic clip abuts against the wire anti-slip grooves; the elastic clip abuts against the bending portion.
[0011] By adopting the above technical solution, when there is no wire connection, the elastic clip presses against the bent part to avoid rebound transition. When the wire is inserted, the wire anti-slip groove is used to increase the friction force in contact with the wire, and the rebound clamping effect of the elastic clip is combined to further increase the stability of the wire connection.
[0012] Optionally, a limiting portion is further provided on the conductive sheet; and a center point of the elastic clip is connected to the limiting portion.
[0013] By adopting the above technical solution, the elastic clip is pressed against the elastic clip by the limiting portion, so that the elastic clip will not be shifted when the control button is pressed, thereby ensuring stable pressing.
[0014] Optionally, the limiting portion is a semicircular plate, the elastic clip is provided with a semicircular groove, and the elastic clip abuts against the semicircular plate through the semicircular groove.
[0015] By adopting the above technical solution, the elastic clip can be tilted along the semicircular surface of the limiting portion, so that the force direction can be shifted downward, expanding the displacement of the elastic clip while not reaching the toughness coefficient of the elastic clip, making the contact of the elastic clip pressing the bent portion more stable.
[0016] Optionally, the power socket is provided with a plurality of card connection ends, and the shell is provided with a plurality of card interfaces, and the shell is card-connected with the power socket via the card interfaces and the card connection ends.
[0017] By adopting the above technical solution, several card interfaces are used to connect with the card terminals, so that the shell does not need to use an additional connection structure with the power socket, such as a bolt lock connection. The connection can be completed by simply inserting the card terminal into the card interface, which improves the convenience of disassembly and assembly.
[0018] Optionally, the control button is provided with a pressing groove at one end outside the shell.
[0019] By adopting the above technical solution, the pressing groove can increase the friction force of workers when pressing, avoiding hand slippage.
[0020] Optionally, the connecting surface between the control button and the elastic clip is a limiting step surface.
[0021] By adopting the above technical solution, the control button utilizes the limiting step surface to contact the other arc surface of the semicircular arc groove of the elastic clip, so that when the control button is pressed to a certain extent, the limiting step surface changes from one step to another step and contacts the arc surface of the elastic clip, thereby achieving the effect of limiting the degree of pressing of the control button and reducing the plastic deformation of the elastic clip.
[0022] Optionally, a button limiting groove is provided on the conductive sheet; when the control button is pressed, it abuts against the groove wall of the button limiting groove.
[0023] By adopting the above technical solution, when the control button is pressed transitionally, the control button will rest against the wall of the button limit slot, making it impossible for the control button to be pressed further, thereby further limiting the degree of pressing of the control button and further reducing the plastic deformation of the elastic clip leading to unstable wire clamping.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] 1. When testing is required, insert the test wire into the test hole and connect it to the bent part of the conductive sheet. There is no need to disassemble the housing for testing, so as to achieve the effect of convenient testing of the terminal. Press the control button, and the control button presses the elastic clamping piece. The elastic clamping piece presses the bent part to the test wire, fixing the position of the wire for power connection test to ensure the accuracy of the test;
[0026] 2. The two electrical ports are used to connect and fix the wires when testing is not required. The elastic clip is pressed downward by pressing the button to separate the elastic clip from the bent part. The wire is then inserted from the electrical port and passed through between the elastic clip and the bent part to the conductive piece to perform normal power connection of the terminal. After releasing the button, the elastic clip rebounds, thereby clamping the wire between the elastic clip and the bent part, ensuring a stable connection of the wire during normal operation.
[0027] 3. When there is no wire connected, the elastic clip presses against the bend to avoid rebound transition. When the wire is inserted, the wire anti-slip groove increases the friction with the wire, and the rebound clamping effect of the elastic clip further increases the stability of the wire connection.
[0028] 4. The limit portion presses against the elastic clip so that the elastic clip will not shift in position when the control button is pressed, thereby ensuring stable pressing. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Throughout this specification, when a device is said to be "connected" to another device, this includes not only "direct connection" but also "indirect connection" with other elements interposed therebetween. Furthermore, when a device is said to "include" a certain component, unless otherwise stated, this does not exclude the inclusion of other components but rather implies that the device may include other components.
[0038] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.
[0039] An embodiment of the present application discloses a connection terminal that is easy to detect.
[0040] A terminal block that is easy to detect, refer to Figure 1 As shown, it includes a shell 1, a power socket 2, a conductive sheet 3, an elastic clip 4 and a control button 5; the power socket 2 is made of insulating material and is used to provide terminal installation and wire connection. The shell 1 is also made of insulating material to ensure the safety of power connection. The shell 1 is connected to the power socket 2 and covers the power socket 2. The space inside the shell 1 is the installation space for components used for detection and power connection.
[0041] The housing 1 is provided with a test hole 11 for power connection testing. The test wire can be inserted into the test hole 11 to perform power connection testing and provide a detection of whether the power connection of the terminal is normal and stable.
[0042] The conductive sheet 3 is installed on the power socket 2 and is located inside the housing 1. The conductive sheet 3 is inside the test hole 11. The conductive sheet is connected to a bent portion 31, which is located next to the test hole 11. Therefore, when the test wire is inserted into the test hole 11, it will contact the bent portion 31 of the conductive sheet 3, thereby performing a power connection test.
[0043] refer to Figure 2 As shown, the elastic clip 4 is located in the housing 1 and extends into the test hole 11 to abut against the bent portion 31. During testing, the elastic clip 4 can use the bent portion 31 to abut the test wire to prevent the wire from swinging or shaking during testing, which affects the connection and testing effects.
[0044] The control button 5 is slidably connected to the shell 1 and contacts the elastic clip 4, so that after the elastic clip 4 is pressed down by the control button 5, the elastic clip 4 contacts the connection wire to ensure the stability of the power connection detection. A sliding opening for the control button 5 to slide is opened on the shell 1, and the control button 5 is provided with a limiting protrusion so that it cannot be separated from the sliding opening, thereby ensuring the stability of the control button 5 in use.
[0045] Specifically, when testing is required, the test wire is inserted into the test hole 11 and connected to the bent portion 31 of the conductive sheet 3. There is no need to disassemble the shell 1 for testing, so as to achieve the effect of convenient detection of the terminal. Press the control button 5, and the control button 5 presses the elastic clamping piece. The elastic clamping piece presses the bent portion 31 to the test wire, fixes the position of the wire, and performs power connection testing to ensure the accuracy of the test.
[0046] For further reference, Figure 1 or Figure 2 As shown, the housing 1 is also provided with two electrical ports 10 for connecting the positive and negative poles of the wires. Both electrical ports 10 are provided with a control button 5. Several elastic clips 4 are provided, and the two ends of a single elastic clip 4 are respectively located below the two electrical ports 10. When the terminal is in normal use, it is necessary to connect the wires to provide normal power connection work, and the positive and negative poles of the wires are respectively inserted through the two electrical ports.
[0047] Specifically, the power port 10 is used to connect and fix the two positive and negative wires when testing is not required. The elastic clip 4 is pressed downward by pressing the button 5 to separate the elastic clip 4 from the bent portion 31. The wire is then inserted from the power port 10 and passes through between the elastic clip 4 and the bent portion 31 to make contact with the conductive sheet 3 to perform normal power connection of the terminal. After releasing the button 5, the elastic clip 4 rebounds, thereby clamping the wire between the elastic clip 4 and the bent portion 31 to ensure that the wire connection is stable during normal operation.
[0048] Among them, there are several elastic clips 4, and the two ends of a single elastic clip 4 are respectively located below the two electrical ports 10. Therefore, by setting multiple elastic clips 4, multiple groups of electrical ports 10 and control buttons 5 will be set, so that multiple groups of wires can be connected and wire clamping tests can be performed on multiple groups of wires, thereby improving test efficiency.
[0049] In some embodiments, reference Figure 2 As shown, the bending portion 31 can be a metal sheet or metal rod arranged in a vertical direction, and bent in the horizontal direction at the same time. The bending portion 31 is arranged along the vertical direction of the conductive sheet 3, and the bending portion extends toward the test hole 11. The bending portion 31 can contact the inner core of the test wire for conductivity.
[0050] The bent portion 31 is provided with a plurality of wire anti-slip grooves 311 at one end near the elastic clip 4. When no wire is connected, the elastic clip 4 uses the wire anti-slip grooves 311 to support the bent portion 31 to prevent rebound transition. When the wire is inserted, the wire anti-slip grooves 311 increase the friction force with the wire, and the rebound clamping effect of the elastic clip 4 further increases the stability of the wire connection.
[0051] When the elastic clip 4 contacts the bent portion 31 , pressure is applied to the bent portion 31 , so that the bent portion 31 bends toward the test hole 11 to contact the test wire.
[0052] Specifically, when the control button 5 is not pressed, the wire is inserted into the power connection port 10, and the elastic clip 4 and the bent portion 31 clamp the wire. When the connection wire needs to be tested, the control button 5 is pressed, and the elastic clip 4 is forced to press the bent portion 31 downward, causing the bent portion 31 to bend toward the test hole 11 until the elastic clip 4 is separated from the wire and the bent portion 31. The wire can then be taken out of the power connection port 10, and the connecting wire is then inserted into the test hole 11. The control button 5 is then pressed again, and the bent portion 31 is bent toward the test hole 11 by the downward pressure of the elastic clip 4, so that the connecting wire in the test hole 11 is pressed tightly by the bent portion 31 to ensure the stability of the test.
[0053] In some embodiments, reference Figure 2 As shown, a limiting portion 12 is further provided on the conductive sheet 3. The limiting portion 12 can be an insulating column or insulating plate made of plastic or other materials. The center of gravity of the elastic clip 4 is connected to the limiting portion 12, so that the two ends of the elastic clip 4 can bend to both sides along the limiting portion 12 to press the bending portion 31 or connect the wires when the control button 5 is pressed respectively, and also prevent the elastic clip 4 from being bent too much when pressed.
[0054] The connection between the elastic clip 4 and the limiting part 12 can be abutment, and the limiting part 12 presses against the elastic clip 4, so that the elastic clip 4 will not be shifted in position when the control button 5 is pressed, ensuring the stability of the pressing. At the same time, the elastic clip 4 also has sufficient toughness to be able to reset, avoiding the loss of elastic force due to pressing exceeding the toughness coefficient of the elastic clip 4.
[0055] Among them, reference Figure 2 As shown, the limiting portion 12 is a semicircular plate, and the elastic clip 4 is provided with a semicircular groove. The elastic clip 4 abuts against the semicircular plate through the semicircular groove. The abutment between the semicircular plate and the semicircular groove enables the elastic clip 4 to tilt along the semicircular surface of the limiting portion 12 when pressed, so that the force direction can be shifted downward, thereby expanding the displacement of the elastic clip 4 while not reaching the toughness coefficient of the elastic clip 4, so that the contact of the elastic clip 4 pressing the bending portion 31 is more stable.
[0056] In some embodiments, reference Figure 2 As shown, the power socket 2 is provided with a plurality of card terminals 21, and the shell 1 is provided with a plurality of card interfaces 13. The shell 1 is connected to the power socket 2 through the card interfaces 13 and the card terminals 21. By using the card interfaces 13 and the card terminals 21 to connect, the shell 1 does not need to use an additional connection structure with the power socket 2, such as a bolt lock connection. The connection can be completed by simply inserting the card terminals 21 into the card interfaces 13.
[0057] When it is necessary to disassemble the shell 1 and the power socket 2, press the card machine end to disengage the card terminal 21 from the card interface 13, and the fixing function of the card terminal 21 is lost. The shell 1 and the power socket 2 can be separated, which improves the convenience of disassembly and assembly. If unqualified is found after testing, it is convenient to separate the shell 1 and the power socket 2 for inspection or replacement of components such as the bending part 31 or the conductive sheet 3.
[0058] In some embodiments, reference Figure 2 As shown, the control button 5 is located at one end outside the shell 1 and is provided with a pressing groove 51. The pressing groove 51 can increase the friction force when the worker presses, avoid hand slippage, and ensure stable pressing.
[0059] Among them, the material of the control button 5 is an insulating material to avoid leakage during testing, to ensure the safety of workers pressing the control button 5 during testing and the safety of the terminal blocks when in use. The insulating material can be made of any material such as PVC, PVE, plastic, rubber, or a plastic surface wrapped with a plastic layer to isolate the conductive transmission of electricity when the test is connected to the power supply.
[0060] For further reference, Figure 2 and Figure 3 As shown, the connecting surface between the control button 5 and the elastic clip 4 is a limiting step surface. The control button 5 uses the limiting step surface to contact the other arc surface of the semicircular arc groove of the elastic clip 4, so that when the control button 5 is pressed to a certain extent, the limiting step surface changes from one step to another step and contacts the arc surface of the elastic clip 4, thereby achieving the effect of limiting the pressing degree of the control button 5 and reducing the plastic deformation of the elastic clip 4.
[0061] Further, refer to Figure 3 As shown, a button limiting groove 32 is opened on the conductive sheet. When the control button 5 is pressed, the control button 5 abuts against the groove wall of the button limiting groove 32 , and the abutting point can be the bottom of the control button 5 .
[0062] Specifically, when the control button 5 is pressed transitionally, the bottom of the control button 5 will rest against the wall of the button limit slot 32, so that the control button 5 cannot be pressed any further, further limiting the degree of pressing of the control button 5, and further reducing the plastic deformation of the elastic clip leading to unstable wire clamping.
[0063] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
