[0002] In the field of electrical signal testing, there is often a need to temporarily connect wires during the test process. The traditional temporary connection of wires is to cut off the existing wires.

[0003] After the test is completed, disconnect the test line from the original circuit, reconnect the original disconnected wire and perform insulation wrapping, or directly perform insulation wrapping on the place where the insulation layer is peeled off.

[0004] Existing technologies have obvious limitations.

[0005] Cutting the wires or stripping off the insulation layer will cause irreversible damage to the original lines, which need to be reconnected and insulated after the test is completed.

[0036] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.

[0037] A wire piercing device for electrical signal testing comprises a clamp body 1, on which a piercing needle 2 is provided; the piercing needle 2 is connected to an external loop wire 5; the wire piercing device disclosed in the present invention; through the coordinated use of the clamp body 1 and the piercing needle 2, a test loop can be connected to an original loop without damaging the original circuit loop; after the test is completed, the test loop is separated from the original loop without causing obvious damage to the original loop.

[0038] The wire piercing device for electric signal testing disclosed by the present invention is mainly used for temporary line connection.

[0039] Specifically, the wire piercing device disclosed in the present invention mainly includes a clamp body 1, on which a piercing needle 2 is provided; the piercing needle 2 is connected to an external loop wire 5; the clamp body 1 is the main structure of the wire piercing device, and a piercing needle 2 is provided on the reinforced body, the piercing needle 2 is mainly used for connecting the external loop wire 5 with the tested loop wire 4, and at the same time the piercing needle 2 is connected to the external loop wire 5; it is convenient to access subsequent test equipment or test loops.

[0040] In the present invention, the clamp body 1 comprises two first clamp rods 11 and second clamp rods 12 which are arranged opposite to each other. In actual design, the first clamp rod 11 and the second clamp rod 12 are similar in overall structure, but are different in specific size and width.

[0041] At the same time, in the present invention, the first clamp rod 11 and the second clamp rod 12 are connected by the rotating part 3; the first clamp rod 11 and the second clamp rod 12 can rotate relative to each other around the rotating part 3; such a configuration facilitates subsequent operators to operate the opening and closing of the clamp body 1.

[0042] At the same time, in the present invention, one end of the first clamp rod 11 and the second clamp rod 12 are connected by a pushing mechanism 6; the first clamp rod 11 and the second clamp rod 12 can be hung on the measured loop wire 4 at one end away from the pushing mechanism 6; the setting of the pushing mechanism 6 can enable the pushing mechanism 6 to control the opening and closing actions of the first clamp rod 11 and the second clamp rod 12.

[0043] An elastic unit (such as a spring) is usually used as the pushing mechanism 6 , and the relative movement of the first pliers rod 11 and the second pliers rod 12 is achieved by pressing and releasing the hand-held handle 112 .

[0044] In the present invention: the clamp body 1 is composed of two oppositely arranged first clamp rods 11 and second clamp rods 12; the first clamp rod 11 and the second clamp rod 12 are connected by a rotating part 3 (such as a rotating pin) and can rotate relatively around the rotating part 3; the clamping function is realized by the relative movement of the clamp rods, and is used to be connected to the circuit wire 4 under test; the piercing needle 2 is arranged on the clamp body 1, usually located near the hanging end of the clamp body 1; it is mainly used to pierce the insulating layer of the circuit wire 4 under test, so that the piercing needle 2 contacts the conductive part of the wire, thereby connecting the circuit under test to the test circuit; the piercing needle 2 is connected to the test equipment through the external circuit wire 5 to realize the transmission of electrical signals.

[0045] At the same time, in the present invention, one end of the first pliers rod 11 and the second pliers rod 12 are connected by a pushing mechanism 6; the pushing mechanism 6 is used to control the opening and closing action of the pliers rods; an elastic unit (such as a spring) is usually used as the pushing mechanism 6, and the relative movement of the pliers rods is achieved by pressing and releasing the handle 112.

[0046] The ends of the first clamp rod 11 and the second clamp rod 12 away from the pushing mechanism 6 are designed as hanging ends; the hanging ends are used to hang on the measured loop wire 4, and the wire is fixed by the clamping force of the clamp to ensure that the piercing needle 2 can accurately penetrate the wire insulation layer and contact the conductor

[0047] In addition, the present invention requires that the pushing mechanism 6 can move on the first clamp rod 11 and the second clamp rod 12, and the change of the squeezing force between the first clamp rod 11 and the second clamp rod 12 is controlled by changing the position of the pushing mechanism 6 on the first clamp rod 11 and the second clamp rod 12.

[0048] Working principle:

[0049] Opening the clamp: the operator holds the handle 112 of the clamp body 1 and presses the handle 112 to make the first clamp rod 11 and the second clamp rod 12 rotate relative to each other around the rotating part 3, and the hanging end is opened.

[0050] Hanging the wire: place the hanging end on the measured loop wire 4 and release the handle 112.

[0051] Piercing the wire: Under the action of the pushing mechanism 6 (such as a spring), the hook end is closed, the clamp clamps the wire, and the piercing needle 2 penetrates the wire insulation layer and contacts the conductor.

[0052] Test completion: After the test is completed, the hand-held handle 112 is pressed again to open the clamp, and the piercing needle 2 is separated from the wire, completing the test.

[0053] Based on the above design, the present invention can non-destructively access the tested circuit through the wire piercing device: the piercing needle 2 pierces the insulating layer without damaging the overall structure of the wire, and the wire can be easily separated after the test is completed.

[0054] The hook-up and piercing operations can be completed with a simple press and release action, which is suitable for quick testing.

[0055] The design of the clamp body 1 enables it to adapt to wires of different diameters and shapes.

[0056] Furthermore, in the present invention, the first clamp rod 11 and the second clamp rod 12 each include a middle clamp rod 111; one end of the middle clamp rod 111 is connected to a hanging rod 113; the other end is connected to a hand handle 112; the hanging rod 113 is an arc-shaped rod; the clamp body 1 is hung on the measured loop wire 4 through the hanging rod 113; in the present invention, the first clamp rod 11 and the second clamp rod 12 each include a middle clamp rod 111, which is the core part of the clamp body 1 and plays a role of connection and support; one end of the middle clamp rod 111 is connected to a hanging rod 113, and the shape of the hanging rod 113 is arc-shaped; this design enables the clamp to better fit the shape of the measured loop wire 4, which is convenient for hanging and fixing; the other end of the middle clamp rod 111 is connected to a hand handle 112, which is used for the operator to hold and operate the clamp.

[0057] The hooking rod 113 in the present invention adopts an arc-shaped design, which can better fit the circular or quasi-circular loop conductor 4 to be tested, increase the contact area, and improve the stability of clamping; through the contraction of the two hooking rods 113, a driving force can be provided for the piercing needle 2, so that the piercing needle 2 can be more stably connected to the loop conductor 4 to be tested; of course, by optimizing the driving force of the driving mechanism 6 and limiting the angle of the hooking rod 113; the overlap degree of the two hooking rods 113 is increased, so that the piercing needle 2 can achieve autonomous piercing, reducing the risk and trouble of manual piercing.

[0058] The clamp body 1 is hooked on the measured loop conductor 4 through the hooking rod 113. This design enables the clamp to be quickly positioned and fixed on the conductor, and is easy to operate.

[0059] Handle 112: The design of the handle 112 is convenient for the operator to hold and apply force. By pressing the handle 112, the opening and closing of the clamp rod can be controlled to achieve the hooking and piercing operations.

[0060] In addition, in the present invention, at least a portion of the clamp body 1 is designed to be insulated, and of course the entire clamp body 1 may be made of insulating material.

[0061] Furthermore, in the present invention, each of the middle clamp rods 111 includes a first rod body 101 and a second rod body 102; the first rod body 101 and the second rod body 102 are arranged to intersect, and the angle between the first rod body 101 and the second rod body 102 is greater than 90 degrees; the middle clamp rod 111 is connected to the hanging rod 113 through the first rod body 101; the middle clamp rod 111 is connected to the hand handle 112 through the second rod body 102; when the clamp body 1 is closed, the first rod body 101 of the first clamp rod 11 and the second clamp rod 12 and the two hanging rods 113 form a closed ring Structure; In the present invention, each middle clamp rod 111 is composed of two intersecting rod bodies, namely the first rod body 101 and the second rod body 102; their intersection angle is greater than 90 degrees, and this design makes the middle clamp rod 111 have a V-shaped structure; such a setting allows the two middle clamp rods 111 to form a bulge where they are close to each other, which is convenient for the subsequent cooperation with the rotating part 3 to realize the relative rotation of the first clamp rod 11 and the second clamp rod 12; at the same time, during subsequent use, it also has a good avoidance effect, preventing the first clamp rod 11 and the second clamp rod 12 from fitting closely and affecting the subsequent wiring operation.

[0062] In addition, because the first clamp rod 11 and the second clamp rod 12 need to rotate with each other, the problem of rotation interference needs to be overcome, so a groove structure 1111 is set on the first clamp rod 11 and / or the second clamp rod 12, and a protrusion is provided inside. The structure can refer to the existing caliper structure.

[0063] In addition, the arrangement of the groove structure 1111 also facilitates the arrangement of the external loop wire 5 on the clamp body 1 .

[0064] In the present invention, the first rod body 101 is connected to the hanging rod 113: one end of the first rod body 101 is connected to the hanging rod 113, and the hanging rod 113 is used to be fixed on the measured loop wire 4; one end of the second rod body 102 is connected to the hand handle 112, and the hand handle 112 is used for the operator to hold and operate the clamp.

[0065] In addition, in the present invention, when the clamp body 1 is closed, the first rod body 101 in the first clamp rod 11 and the second clamp rod 12 and the two hanging rods 113 will form a closed ring structure; this closed ring structure can ensure that the clamp forms a stable clamping force on the loop wire 4 under test in the closed state, preventing the wire from loosening or falling off during the test, thereby ensuring the stability and reliability of the test.

[0066] At the same time, in the present invention, the angle between the first rod body 101 and the second rod body 102 is greater than 90 degrees. This design enables the clamp to have better mechanical properties during operation and can provide greater clamping force and stability.

[0067] The closed ring structure and the angle design greater than 90 degrees enable the clamp to provide a stable clamping force in the closed state, ensuring that the loop conductor 4 under test will not loosen during the test; at the same time, this structural design makes the opening and closing operation of the clamp smoother, and the operator can complete the hooking and piercing operations through simple pressing and releasing actions.

[0068] Since the closed ring structure formed by the hanging rod 113 and the first rod body 101 can adapt to wires of different diameters, the device has strong versatility and is suitable for a variety of testing scenarios.

[0069] Furthermore, in the present invention, the rotating part 3 includes a rotating pin; the first clamp rod 11 and the second clamp rod 12 are connected by a rotating pin; the piercing needle 2 is connected to the rotating pin; the core component of the rotating part 3 of the present invention is the rotating pin, which is used to connect the first clamp rod 11 and the second clamp rod 12 so that the two can rotate relative to each other.

[0070] The first clamp rod 11 and the second clamp rod 12 are connected by a rotating pin: this connection mode enables the clamp rod to be flexibly opened and closed, similar to the structure of common clamps or pliers.

[0071] The piercing needle 2 is connected to the rotating pin shaft: the piercing needle 2 is fixed on the rotating pin shaft, and along with the opening and closing action of the clamp rod, the piercing needle 2 can accurately pierce into or withdraw from the insulation layer of the loop conductor 4 to be tested.

[0072] Function of the rotating pin: The rotating pin serves as a center point of connection and rotation, so that the first clamp rod 11 and the second clamp rod 12 can flexibly move relative to each other to realize the opening and closing operation of the clamp.

[0073] The piercing needle 2 is connected to the rotating pin, and can be specifically fixed on the rotating pin: this design ensures that the piercing needle 2 always maintains a stable position during the opening and closing of the clamp rod, and can accurately pierce the insulation layer of the measured loop conductor 4.

[0074] It is required that the median hammer lines of the two hanging rods 113 intersect with each other; at the same time, it is required that the central axis of the piercing needle 2 passes through the intersection point of the median hammer lines of the two hanging rods 113 .

[0075] Based on such a configuration, it is convenient for the puncture needle 2 to puncture and connect the loop wire 4 to be tested.

[0076] Furthermore, in the present invention, a protective mechanism is provided on the piercing needle 2, and the protective mechanism includes an insulating layer arranged on the piercing needle 2; the height of the insulating layer is less than the height of the piercing needle 2, and the end of the piercing needle 2 is located outside the insulating layer; in the present invention, the insulating layer on the piercing needle 2 is mainly used to protect the safety of the operator and prevent electrical short circuits or electric shock accidents when piercing the insulating layer of the wire.

[0077] The design of the insulating layer ensures that the piercing needle 2 is adequately electrically isolated from the operator during operation, thereby improving the safety of use.

[0078] The height of the insulating layer is smaller than the height of the piercing needle 2: this design ensures that the needle tip of the piercing needle 2 can be exposed to the outside so as to pierce the insulating layer of the loop conductor 4 to be tested.

[0079] At the same time, the height limit of the insulating layer also ensures that the needle tip can accurately contact the conductive part of the wire during the piercing process.

[0080] The end of the piercing needle 2 is outside the insulating layer: this design ensures that when the piercing needle 2 pierces the insulating layer of the wire, the needle tip will not be wrapped by the insulating layer, thereby ensuring the accuracy and effectiveness of the piercing.

[0081] The specific material of the insulating layer on the piercing needle 2 is usually selected from materials with high insulation performance and voltage resistance, such as polytetrafluoroethylene (PTFE), polyimide (PI), etc.; these materials can not only provide good electrical insulation performance, but also prevent wear and corrosion of the needle tip to a certain extent.

[0082] Furthermore, in the present invention, the widths of the hanging rods 113 in the first clamp rod 11 and the second clamp rod 12 are different; an avoidance groove 1131 is provided at the end of the hanging rod 113 with a larger width; because the first clamp rod 11 and the second clamp rod 12 of the present invention are not relatively symmetrically arranged, and in order to better provide external force for the puncture needle 2 to ensure the stability of its position after puncture, the present invention requires that the first clamp rod 11 and the second clamp rod 12 have a partial overlap, specifically refer to the accompanying drawings, therefore, in order to avoid interference, the widths of the hanging rods 113 in the first clamp rod 11 and the second clamp rod 12 are required to be different; an avoidance groove 1131 is provided at the end of the hanging rod 113 with a larger width; the avoidance groove 1131 allows the clamp rod with a smaller width to pass through the other clamp rod, thereby achieving partial overlap between the two.

[0083] An avoidance groove 1131 is provided at the end of the wider hook rod 113, allowing the smaller clamp rod to pass through, thereby achieving partial overlap of the two; this design avoids interference between the clamp rods and ensures that the clamp can be stably fixed on the wire when closed; the design of the avoidance groove 1131 increases the flexibility of the clamp, enabling it to adapt to some irregular shapes on the wire, such as joints or thickened parts of the insulation layer.

[0084] Furthermore, in the present invention, each of the middle clamp rods 111 and the connecting rod 113 and / or the hand handle 112 connected thereto are connected in a detachable manner; the specific connection method may be a threaded connection or a bolt connection, and the specific connection method is selected according to needs.

[0085] The connection between the middle clamp rod 111 and the hanging rod 113 or the hand handle 112 of the present invention adopts a detachable design, which is easy to maintain: the detachable connection method allows the user to easily replace the damaged hanging rod 113 or the hand handle 112 without replacing the entire clamp body 1, thereby reducing maintenance costs.

[0086] The user can select different specifications of the hanging rod 113 or the hand-held handle 112 according to different test requirements or wire diameters, thereby improving the versatility and flexibility of the device.

[0087] The detachable design makes it easier and quicker to replace parts.

[0088] The disassembled design allows the user to replace only the damaged parts without replacing the entire unit, reducing maintenance costs.

[0089] The user can select different specifications of the hanging rod 113 or the hand-held handle 112 according to the test requirements, thereby improving the versatility and adaptability of the device.

[0090] The detachable connection mode makes it more convenient and quick to replace parts, reduces the operation steps and improves work efficiency.

[0091] By replacing worn parts, the service life of the entire device is extended.

[0092] Furthermore, in the present invention, the pushing mechanism 6 includes an elastic unit, and both ends of the elastic unit are respectively connected to the first clamp rod 11 and the second clamp rod 12; the core component of the pushing mechanism 6 is the elastic unit, which is usually made of a spring or other elastic materials; the two ends of the elastic unit are respectively connected to the first clamp rod 11 and the second clamp rod 12; this connection method enables the elastic unit to transmit force between the clamp rods to realize the opening and closing action of the clamp.

[0093] Meanwhile, in the present invention, the elastic unit and the first clamp rod 11 and the second clamp rod 12 can be connected in a detachable connection manner or other connection manners.

[0094] Keep clamping in natural state: in natural state, the elastic unit (such as a spring) is in a compressed state, so that the first clamp rod 11 and the second clamp rod 12 are kept in a clamping state; this design ensures that the clamp can stably clamp the measured wire when not in operation.

[0095] The clamping force is released during operation: when the operator presses the hand-held handle 112, the elastic unit is further compressed, and the clamp rod opens to facilitate hooking the wire; after releasing the hand-held handle 112, the elastic unit returns to its original state, the clamp rod closes, and the wire is clamped.

[0096] Simple operation: Through the design of the elastic unit, the operator only needs to press the handle 112 to open the clamp, and release the handle 112 to close the clamp, which is simple and quick to operate.

[0097] The automatic reset function of the elastic unit enables the clamp to automatically return to the clamping state after the operation is completed, reducing the operation steps and improving work efficiency.

[0098] A method for using the wire piercing device, the method comprising the following steps:

[0099] S1: holding the two handles 112 of the clamp body 1; then pressing the handles 112; the two hooking rods 113 of the clamp body 1 open;

[0100] S2: After step S1 is completed, the operator releases the hand-held handle 112 to close the hook rod 113; then the hand-held clamp is hooked on the circuit to be measured; at the same time, the piercing needle 2 pierces the insulation layer of the wire 4 of the circuit to be measured, and the piercing needle 2 is connected to the conductor of the wire to be measured, so that the circuit to be measured and the measuring circuit are connected;

[0101] S3: After step 2 is completed, the test loop is connected to the tested loop conductor 4; if other test loops need to be connected to the corresponding tested loop, repeat the above steps S1-S2.

[0102] The present invention requires that the method for using the wire piercing device mainly includes three steps: opening the clamp, hanging the wire and piercing the insulation layer, and completing the access of the test loop.

[0103] When in use, it is necessary to adjust the position of the pushing mechanism on the first clamp rod 11 and the second clamp rod 12. By adjusting the position of the pushing mechanism on the first clamp rod 11 and the second clamp rod 12, the supporting force between the first clamp rod 11 and the second clamp rod 12 is adjusted; the elastic unit can be inserted into the connecting holes on the first clamp rod 11 and the second clamp rod 12 by bolts or connecting columns; in other words, the end of the elastic unit of the present invention can be screwed into the threaded hole on the first clamp rod 11 or the second clamp rod 12 by connecting bolts.

[0104] Step S1: Open the clamp

[0105] Operation: Hold the two handles 112 of the clamp body 1 and then press the handles 112 .

[0106] Result: The two hooking rods 113 of the clamp body 1 are opened.

[0107] Purpose: By pressing the handle 112, the hooking rod 113 is opened to prepare for hooking the measured loop wire 4

[0108] Step S2: Hook the wire and pierce the insulation

[0109] Operation: Release the handle 112 and move the hook rod 113 toward closing.

[0110] result:

[0111] The hooking rod 113 is closed, and the clamp body 1 is hooked on the loop conductor 4 to be tested.

[0112] The piercing needle 2 pierces the insulation layer of the measured loop wire 4 and is connected to the conductor of the wire.

[0113] The circuit under test is conductive with the measuring circuit.

[0114] Purpose: By releasing the handle 112, the restoring force of the elastic unit (such as a spring) is used to close the hook rod 113 and clamp the wire, and at the same time, the piercing needle 2 penetrates the insulation layer of the wire to ensure the electrical connection between the circuit under test and the test circuit.

[0115] Step S3: completing the access of the test loop;

[0116] Operation: After step S2 is completed, the test loop has been connected to the tested loop conductor 4.

[0117] Result: The test loop is connected to the tested loop wire 4, and the electrical signal test can begin.

[0118] Purpose: To complete the access of the test loop and ensure the smooth progress of the test process.

[0119] Repeat operation: If you need to access other test loops, repeat steps S1 and S2.

[0120] Furthermore, in S2 of the present invention, the piercing needle 2 is required to pierce the insulating layer on the loop conductor 4 to be tested first, and then the operator releases the hand-held handle 112 .

[0121] The puncture needle 2 first pierces the insulating layer, which can ensure the accuracy of the puncture point and avoid inaccurate puncture position caused by slight displacement during the release of the hand-held handle 112.

[0122] This operation sequence can effectively reduce the damage to the insulation layer of the wire during the piercing process, and ensure that the piercing needle 2 can accurately contact the conductive part of the wire.

[0123] Piercing the insulating layer first and then releasing the handle 112 can avoid the risk of accidental electric shock due to improper operation during the piercing process.

[0124] This operation sequence can ensure that after the piercing needle 2 pierces the wire, the clamp body 1 can be stably fixed on the wire, thereby improving the safety of the entire testing process. Specific embodiment:

[0126] The wire piercing device disclosed in the present invention mainly relates to temporary line connection in the test field. The test circuit is connected to the original circuit with less damage to the original circuit. After the test is completed, the test circuit is separated from the original circuit without causing obvious damage to the original circuit.

[0127] The test clamp mainly comprises a clamp body 1, wherein the clamp body 1 comprises two oppositely arranged first clamp rods 11 and second clamp rods 12; the first clamp rod 11 and the second clamp rod 12 are connected via a rotating part 3; the test clamp is mainly used for clamping the loop conductor 4 to be tested.

[0128] The pushing mechanism 6 mainly includes a spring, which supports the clamp body 1 in a natural state to keep the clamp body 1 in a clamped state.

[0129] The external loop wire 5 and the wire piercing needle 2 remain connected so as to connect the circuit under test into the test circuit.

[0130] The piercing needle 2, except for the needle tip, is wrapped with an insulating layer;

[0131] The measured loop conductor 4 mainly includes an insulating layer 42 and a core conductor 41 .

[0132] When the circuit under test needs to be temporarily connected to the test circuit during the test process, the conductive connection is made by the wire piercing device of the present invention, and the steps are as follows:

[0133] S1: holding the handle 112 of the test clamp body 1 and pressing the handle hard;

[0134] S2: The clamp body 1 is under stress, the spring is compressed, and the clamping end is opened;

[0135] S3: The wire piercing needle 2 pierces the insulation layer of the measured circuit wire 4, and the needle tip is connected to the conductor of the measured wire, so that the measured circuit and the measuring circuit are connected;

[0136] S4: the hand pressure on the handheld terminal is released;

[0137] S5: The handle of the clamp handheld end opens outwards under the action of the spring, and the other end of the clamp is clamped accordingly;

[0138] S6: As the clamping end of the clamp is clamped, the clamping force is finally applied to the loop wire 4 under test, forcing the wire to move toward the wire piercing needle 2, so that the wire and the piercing needle 2 are in closer contact, thereby maintaining good contact during the test process.

[0139] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
