Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of acoustic equipment testing, in particular to a terminal line signal detection tool. Background Art
[0002] After some acoustic devices are manufactured, the acoustic signals they output need to be tested. This is usually done by connecting the test line of the acoustic device to a detection device and using a level signal to detect whether the acoustic signal is normal.
[0003] However, in the actual detection process, it is often found that the test line cannot be powered on normally. After investigation, it is found that this is because the test line has poor contact when inserted into the detection equipment. The staff needs to squeeze it with a multimeter pen so that the test line insertion part fits tightly with the detection equipment interface for normal detection.
[0004] However, this also brings a problem, because not all acoustic devices will have this situation during detection, so detection in this way will only be performed when necessary. This also means that the multimeter pen is usually selected for use by humans. When using the multimeter pen, excessive force may cause damage to the test line insertion part, and improper use of the multimeter pen may cause a short circuit, causing unnecessary impact. Utility Model Content
[0005] The problem solved by the utility model is to provide a terminal line signal detection tool, which can effectively clamp the test line for testing, prevent poor contact, and will not cause a short circuit.
[0006] In order to solve the above problems, the utility model provides a terminal line signal detection tooling, including an upper clamping plate, a lower clamping plate, a connecting piece and an elastic piece; a plurality of clamping holes for inserting test lines to form a limit are opened at the end position of the upper clamping plate; the upper end of the elastic piece is fixed to the lower surface of the upper clamping plate, the lower end is fixed to the upper surface of the lower clamping plate, and the elastic piece is arranged on the side away from the clamping hole; the connecting piece is arranged between the elastic piece and the clamping hole, the lower end of the connecting piece is fixed to the lower clamping plate, and the upper end is hinged to the middle part of the upper clamping plate, so that the upper clamping plate can rotate up and down around the hinge point.
[0007] Compared with the prior art, the present application has the following advantages: the test line is inserted into the wire clamping hole to be fixed, and since an elastic member is provided between the upper clamping plate and the lower clamping plate, when the test line needs to be inserted into the detection device, the end of the upper clamping plate close to the elastic member can be pressed downward to make the upper clamping plate rotate around the hinge point, so that the side of the upper clamping plate where the wire clamping hole is provided will open upward, and then the end of the test line is inserted into the detection device, and due to the resetting force of the elastic member, the test line can be pressed tightly against the interface of the detection device to prevent poor contact, and the present application does not require the insertion of additional components in the interface of the detection device, so it will not cause a short circuit.
[0008] In a possible implementation, the side of the upper clamping plate close to the elastic member is higher than the side of the upper clamping plate where the wire clamping hole is provided.
[0009] Compared with the prior art, the above technical solution enables the detection line to be more easily tightened by the elastic member when it is reset.
[0010] In a possible implementation, the wire clamping hole passes through the upper and lower ends of the upper clamping plate. When the test wire is inserted into the wire clamping hole, the end of the test wire extends out and a gap is left between the end and the lower clamping plate.
[0011] Compared with the prior art, the above technical solution can prevent the end of the test line from being easily damaged by colliding with the lower clamping plate when the test line is inserted into the clamp.
[0012] In a possible implementation manner, a through hole is provided in the middle of the upper clamping plate, and the upper end of the connecting member is hinged to the inner side wall of the through hole.
[0013] Compared with the prior art, the above-mentioned technical solution enables the upper splint to rotate around the hinge point in the middle, so that when one end of the upper splint is pressed, the other end is opened, or when one end of the upper splint is released, the other end is reset; and the upper end of the connecting piece is hinged in the through hole, which will not take up extra space and will not affect other components, which is conducive to practical operation.
[0014] In a possible implementation manner, a pressing block for a user to press is fixed on one side of the upper clamping plate close to the elastic member.
[0015] Compared with the prior art, the above technical solution can facilitate users to press through the pressing block, which is conducive to pressing force.
[0016] In a possible implementation manner, a rounded transition surface is provided on one end of the upper clamping plate and the lower clamping plate close to the elastic member.
[0017] Compared with the prior art, the above technical solution can prevent users from using excessive force or slipping their hands and getting cut when pressing.
[0018] In a possible implementation, the thread clamping holes are evenly distributed along the width direction of the upper clamping plate.
[0019] Compared with the prior art, the above technical solution can arrange the wire clamping holes evenly, which is conducive to the insertion of the test wires in a row and more efficient.
[0020] In a possible implementation manner, the elastic member is a coil spring.
[0021] Compared with the prior art, the above technical solution can facilitate the elastic member to be subjected to axial force and also reset in the axial direction when the upper clamping plate is pressed. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0029] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments. Figure 2 This is a three-dimensional schematic diagram of the present application when testing acoustic equipment.
[0030] In some embodiments, a terminal line signal detection tooling includes an upper clamping plate 1, a lower clamping plate 2, a connecting piece 3 and an elastic piece 4; a plurality of clamping holes 11 for inserting test lines to form a limit are opened at the end position of the upper clamping plate 1; the upper end of the elastic piece 4 is fixed to the lower surface of the upper clamping plate 1, and the lower end is fixed to the upper surface of the lower clamping plate 2, and the elastic piece 4 is arranged on the side away from the clamping hole 11; the connecting piece 3 is arranged between the elastic piece 4 and the clamping hole 11, the lower end of the connecting piece 3 is fixed to the lower clamping plate 2, and the upper end is hinged to the middle part of the upper clamping plate 1, so that the upper clamping plate 1 can rotate up and down around the hinge point.
[0031] In this embodiment, the lower clamping plate 2 is arranged in the horizontal direction and is located below the upper clamping plate 1, and the bottom surface of the lower clamping plate 2 is arranged to be a horizontal plane, which is used to be placed on an external support platform or held in the hand, which is convenient for the user to press the upper clamping plate 1. The diameter of the wire clamping hole 11 is equal to or slightly larger than the diameter of the test line, so that the test line is inserted into the wire clamping hole 11 to be fixed. Since an elastic member 4 is arranged between the upper clamping plate 1 and the lower clamping plate 2, when the test line needs to be inserted into the detection device, the end of the upper clamping plate 1 close to the elastic member 4 can be pressed downward so that the upper clamping plate 1 is rotated around the hinge point, so that the side of the upper clamping plate 1 where the wire clamping hole 11 is arranged will open upward, and then the end of the test line is inserted into the detection device. Due to the reset force of the elastic member 4, the test line can be pressed tightly in the interface of the detection device to prevent poor contact, and the present application does not need to insert additional components into the interface of the detection device, so it will not cause a short circuit.
[0032] In some embodiments, the upper clamping plate 1 is tilted downward so that the side of the upper clamping plate 1 close to the elastic member 4 is higher than the side of the upper clamping plate 1 where the clamping hole 11 is provided, so that the detection line is more easily pressed by the elastic member 4 when it is reset.
[0033] In some embodiments, the wire clamping hole 11 passes through the upper and lower ends of the upper clamping plate 1 . When the test wire is inserted into the wire clamping hole 11 , the end of the test wire extends out and a gap is left between the lower clamping plate 2 .
[0034] In this embodiment, a larger gap can be left between the side of the upper clamping plate 1 where the wire clamping hole 11 is provided and the lower clamping plate 2, so that when the test line is inserted and clamped, a gap can still be left between the test line end of the test line and the lower clamping plate 2, making it difficult for the end of the test line to collide with the lower clamping plate 2 and be damaged.
[0035] In some embodiments, a through hole 12 is provided in the middle of the upper clamping plate 1 , and the upper end of the connecting member 3 is hinged to the inner wall of the through hole 12 .
[0036] In this embodiment, the upper splint 1 can be rotated around the hinge point in the middle, so that when one end of the upper splint 1 is pressed, the other end is opened, or when one end of the upper splint 1 is released, the other end is reset; and the upper end of the connecting member 3 is hinged in the through hole 12, which does not take up more extra space and does not affect other components, which is conducive to actual operation.
[0037] In some embodiments, a pressing block 13 for a user to press is fixed on one side of the upper clamping plate 1 close to the elastic member 4. This facilitates the user to press through the pressing block 13, which is conducive to pressing and exerting force.
[0038] In some embodiments, the upper clamping plate 1 and the lower clamping plate 2 are both provided with a rounded transition surface at one end close to the elastic member 4. The rounded transition surface can prevent the user from applying excessive force or slipping out of the hand and getting cut when pressing.
[0039] In some embodiments, the thread clamping holes 11 are evenly distributed along the width direction of the upper clamping plate 1 .
[0040] In this embodiment, the wire clamping holes 11 are arranged in a single row. This structure enables the wire clamping holes 11 to be evenly arranged, which is beneficial for inserting the test wires in a whole row and is more efficient.
[0041] In some embodiments, the elastic member 4 is a spiral spring, so that when the upper clamping plate 1 is pressed, the elastic member 4 is stressed in the axial direction and resets in the axial direction, which further facilitates the upper clamping plate 1 to rotate up and down around the hinge point and reset.
