Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrical equipment, in particular to a socket, a test circuit board and a detection device. Background Art
[0002] The name of the banana plug comes from its slightly bulging shape. After being inserted, it can form a very large contact area. This feature makes it preferentially used in high-power output equipment. It originated in Germany after World War I. The original form was assembled from a base, iron nails and shrapnel. Since the original shrapnel was stamped into four leaf shapes from metal sheets, it was inverted after being assembled into the iron nails, just like a banana peeled into four pieces, so it was named "banana plug". The banana plug has been gradually applied to industrial instruments, teaching instruments, power testing, radio models, medical instruments, automobile testing, audio equipment and other fields due to its excellent electrical performance, simple assembly method and low price.
[0003] In integrated circuit testing, especially for power device testing, 4mm banana plugs and banana sockets are usually used as connectors to conduct large currents. After high-frequency plugging and unplugging, the elasticity of the reed of the banana plug is weakened, resulting in ineffective contact between the banana plug and the banana socket, causing the test circuit to be broken, which poses a serious hidden danger to the test of power devices. Therefore, there is an urgent need for a socket, a test circuit board and a detection device that can quickly and accurately test whether the plug and the socket are connected after the plug is inserted into the socket. Utility Model Content
[0004] In view of the above problems in the prior art, the present application provides a socket, a test circuit board and a detection device, which can quickly and accurately test whether a connection is achieved between the plug and the socket after the plug is inserted into the socket.
[0005] To achieve the above-mentioned purpose, the first aspect of the present application provides a socket, comprising: a main body, on which a socket is arranged; a first connecting part, a part of which is located on the surface of the main body, and another part is located on the inner circumference of the socket; a second connecting part, which is separated from the first connecting part, a part of which is located on the surface of the main body, and another part is located on the inner circumference of the socket.
[0006] As described above, by separately setting the first connection part and the second connection part, after the plug is inserted into the socket, the first connection part and the second connection part can be detected by using, for example, a test circuit to detect whether a loop is formed between the first connection part and the second connection part, thereby being able to quickly and accurately test whether an electrical connection is achieved between the plug and the socket.
[0007] As a possible implementation manner of the first aspect, the first connection portion and / or the second connection portion is copper plating.
[0008] As described above, by providing the first connection portion and the second connection portion in a copper plating manner, the effect of electrical connection can be improved and the production cost can be reduced.
[0009] As a possible implementation of the first aspect, portions of the first connection portion and the second connection portion located on the inner surface of the socket extend along the axial direction of the socket, and portions of the first connection portion and the second connection portion located on the surface of the main body portion are located on the top and side surfaces of the main body portion; further comprising: an isolation portion, a portion of which is located on the surface of the main body portion, and another portion of which is located on the inner circumferential surface of the socket, and is arranged between the first connection portion and the second connection portion to separate the second connection portion from the first connection portion.
[0010] As described above, by making the first connection part and the second connection part located on the inner surface of the socket extend axially along the socket, the connection effect between the plug and the first connection part and the second connection part can be improved after the plug is inserted into the socket.

[0014] As described above, by providing a plurality of first connection parts and second connection parts, the first connection parts and second connection parts can be set according to the number of spring pieces on the plug. Therefore, after the plug is inserted into the socket, it is possible to determine the position where the plug and the socket are not connected by detecting whether a loop is formed between a first connection part and a second connection part. In this way, the detection accuracy and detection effect can be improved, and the plug can be repaired and adjusted conveniently.
[0015] As a possible implementation manner of the first aspect, the first connection portion and the second connection portion have the same curvature on the inner surface of the insertion hole.
[0016] As described above, since the spring pieces on the plug are usually evenly arranged along the circumference, by making the first connection part and the second connection part have the same curvature, the connection between the spring piece and the first connection part and the second connection part can be made more uniform, thereby improving the connection effect. It can also improve the detection accuracy during detection, so as to more accurately determine the position where the plug and the socket are not connected.
[0017] As a possible implementation manner of the first aspect, it further includes: a clamping area, wherein the clamping area is arranged on a side of the main body.
[0018] From the above, by setting a clamping area on the main body, it is convenient to perform copper plating on the main body.

[0020] As described above, the socket can be mounted on the pad, the first connection part is connected to the third connection part, and the second connection part is connected to the fourth connection part, and then the first connection part and the second connection part can be tested by the test circuit. By detecting whether a loop is formed between the first connection part and the second connection part, it is possible to quickly and accurately test whether the plug and the socket are electrically connected.
[0021] As a possible implementation manner of the second aspect, the pad is a surface mount pad.
[0022] From the above, by using the surface mount pad, it is convenient to solder to the socket and to layout and wire on the circuit board.

[0044] Below, in conjunction with the accompanying drawings, possible embodiments of the socket 100 in the present application are exemplarily described.
[0045] Figure 1 It is a schematic diagram of the three-dimensional structure of the socket 100 in this application; Figure 2 for Figure 1 A schematic diagram of the top orthographic projection structure of the middle socket 100; Figure 3 for Figure 1 A schematic diagram of the bottom orthographic projection structure of the middle socket 100; Figure 4 for Figure 1 A schematic diagram of the left side orthographic projection structure of the middle socket 100; Figure 5 for Figure 1 A schematic diagram of the right side orthographic projection structure of the middle socket 100; Figure 6 for Figure 1 A schematic diagram of the front side orthographic projection structure of the middle socket 100; Figure 7 for Figure 1 A schematic diagram of the rear side orthographic projection structure of the middle socket 100.
[0046] like Figure 1-Figure 7 As shown, the socket 100 in the present application includes a main body 110, a first connection part 120 and a second connection part 130. Among them, a plug hole 111 is provided on the main body 110, a part of the first connection part 120 is located on the surface of the main body 110, and another part is located on the inner circumference of the plug hole 111. The second connection part 130 is separated from the first connection part 120, a part of the second connection part 130 is located on the surface of the main body 110, and another part is located on the inner circumference of the plug hole 111. Therefore, by separating the first connection part 120 from the second connection part 130, after the plug 20 is inserted into the socket 100, the first connection part 120 and the second connection part 130 can be tested by using, for example, a test circuit 220 to detect whether a loop is formed between the first connection part 120 and the second connection part 130, so that it is possible to quickly and accurately test whether the plug 20 and the socket 100 are electrically connected.
[0047] In some embodiments, the main body 110 may be Figure 1-Figure 7 The cube shape shown may also be a rectangular parallelepiped, a cylinder or other suitable shapes.
[0048] In some embodiments, the first connection portion 120 and / or the second connection portion 130 are copper-plated. Thus, by using copper-plated method to arrange the first connection portion 120 and the second connection portion 130, the effect of electrical connection can be improved and the production cost can be reduced.
[0049] In some embodiments, the first connection portion 120 and the second connection portion 130 may also be metal components fixed to the main body 110 by means of snap-fitting, welding, gluing, etc., and there is no limitation to this.
[0050] In some embodiments, Figure 1-Figure 7As shown, the first connection part 120 and the second connection part 130 located on the inner surface of the jack 111 extend along the axial direction of the jack 111, and the first connection part 120 and the second connection part 130 located on the surface of the main body 110 are located on the top and side of the main body 110. The socket 100 further includes a separation part 140, a part of which is located on the surface of the main body 110, and the other part is located on the inner circumference of the jack 111, and is arranged between the first connection part 120 and the second connection part 130, so that the second connection part 130 is separated from the first connection part 120. Thus, by making the first connection part 120 and the second connection part 130 located on the inner surface of the jack 111 extend along the axial direction of the jack 111, the connection effect between the plug 20 and the first connection part 120 and the second connection part 130 can be improved after the plug 20 is inserted into the jack 111.
[0051] In some embodiments, the arc of the portion of the second connection portion 130 located on the inner surface of the jack 111 is between 30° and 40°. Thus, by making the arc of the portion of the second connection portion 130 located in the jack 111 between 30° and 40°, at least one spring piece 22 (petal) on the plug 20 can be successfully contacted and connected with the second connection portion 130. It should be noted that the size of the arc is not limited to between 30° and 40°, and in other embodiments, it can also be other parameters, as long as the plug 20 is successfully contacted and connected with the second connection portion and the first connection portion.
[0052] In some embodiments, the socket 100 further includes a clamping area 150, which is disposed on the side of the main body 110. Thus, by disposing the clamping area 150 on the main body 110, it is convenient to perform copper plating on the main body 110. When forming the first connection part 120 and the second connection part 130, a tool is used to clamp the clamping area 150 to fix the main body 110, so as to perform copper plating on the main body 110.
[0053] In some embodiments, the clamping areas 150 are arranged in pairs at opposite positions on the main body 110 so that a clamping tool can contact the clamping areas 150 to clamp and fix the main body 110 .
[0054] In some embodiments, the clamping area 150 is rectangular and extends in the up-down direction. Two pairs of clamping areas 150 are provided, one pair is located at the left end of the front and rear surfaces of the main body 110, and the other pair is located at the right end of the front and rear surfaces of the main body 110. Thus, the stability of the clamping tool when clamping the main body 110 can be improved.
[0055] In some embodiments, the jack 111 is in the form of a through hole, and two isolating parts 140 are provided in an annular shape on the inner circumference of the jack 111 and the top, right side, and bottom surfaces of the main body 110. The first connecting part 120 and the second connecting part 130 are formed by copper plating on the surface of the main body 110 and the inner circumference of the jack 111, and the first connecting part 120 and the second connecting part 130 are separated by two isolating parts 140.
[0056] Figure 8 FIG. 1 is a schematic diagram of the top projection structure of another socket 100 in this application. Figure 8 As shown, in some embodiments, the first connection part 120 and / or the second connection part 130 are provided in plurality. Thus, by providing a plurality of first connection parts 120 and second connection parts 130, the first connection parts 120 and the second connection parts 130 can be provided according to the number of the spring pieces 22 on the plug 20. Thus, after the plug 20 is inserted into the jack 111, the position where the plug 20 and the socket 100 are not connected can be determined by detecting whether a loop is formed between a first connection part 120 and a second connection part 130. Thus, the detection accuracy and detection effect can be improved, and the repair and adjustment of the plug 20 can be facilitated.
[0057] In some embodiments, Figure 8 As shown, the first connection part 120 and the second connection part 130 have the same curvature on the inner surface of the jack 111. Therefore, since the spring pieces 22 on the plug 20 are usually evenly arranged along the circumference, by making the first connection part 120 and the second connection part 130 have the same curvature, the connection between the spring piece 22 and the first connection part 120 and the second connection part 130 can be made more uniform, thereby improving the connection effect. It can also improve the detection accuracy during detection, so as to more accurately determine the position where the plug 20 and the socket 100 are not connected.
[0058] In some embodiments, the socket 100 in the present application may be a banana socket or other types of sockets, and is not limited thereto.
[0059] The above content is an example description of a possible embodiment of the socket 100 in the present application. Next, in conjunction with the accompanying drawings, taking a banana plug and a banana socket as an example, the specific structure of the detection device 10 in an embodiment is described in detail.
[0060] Fig. 9 It is a schematic diagram of the front projection structure of the detection device 10 in this application; Fig.10 for Fig. 9 The top orthographic structure diagram of the detection device 10 is shown in FIG. Fig.10(a) shows a schematic diagram of a state in which the spring piece 22 of the plug 20 is connected to the first connection part 120 and the second connection part 130 of the socket 100 after the plug 20 is inserted into the socket 100, and (b) shows a schematic diagram of a state in which the spring piece 22 of the plug 20 is not connected to the first connection part 120 and the second connection part 130 of the socket 100 after the plug 20 is inserted into the socket 100; Fig.11 for Fig. 9 Schematic diagram of the structure of the test circuit board 200.
[0061] like Fig. 9 , Fig.10 As shown, the plug 20 includes a plug portion 21 and a spring sheet 22. The plug portion 21 is cylindrical with a diameter of 4 mm, and a spring sheet 22 is arranged on the outer peripheral surface of the plug portion 21. The spring sheet 22 extends along the axial direction of the plug so that the plug portion 21 can be inserted into the socket 111 described below. The spring sheet 22 is made of a metal material with a certain elasticity to improve the connection effect between the plug portion 21 and the socket 111. A plurality of spring sheets 22 are provided, and the plurality of spring sheets 22 are evenly arranged along the axial direction of the plug portion 21, thereby improving the connection effect between the plug portion 21 and the socket 111.
[0062] like Figure 9-11 As shown, the detection device 10 in the present application includes a socket 100 and a test circuit board 200. The socket 100 is mounted on the test circuit board 200, the socket 100 is used for plugging and unplugging with the plug 20, and the test circuit board 200 is used to detect whether the socket 100 and the plug 20 are electrically connected.
[0063] like Figure 1-Figure 7 As shown, the socket 100 includes a main body 110, a first connecting part 120, a second connecting part 130, an isolating part 140 and a clamping area 150. The main body 110 is in a rectangular parallelepiped shape, and a plug hole 111 is provided at the middle position of the top of the main body 110. The plug hole 111 is in a circular through hole shape, and the diameter of the plug hole 111 is 4 mm, and is used for inserting a plug 20 with a diameter of 4 mm.
[0064] like Figure 1 , Figure 6 , Figure 7 As shown, the clamping area 150 is rectangular and extends in the up-down direction. Two pairs of clamping areas 150 are provided, one pair is located at the left end position of the front and rear surfaces of the main body 110, and the other pair is located at the right end position of the front and rear surfaces of the main body 110. Therefore, a clamping tool can be used to clamp the clamping area 150 of the main body 110 from the front and rear sides to facilitate copper plating on the surface of the main body 110 and the inner peripheral surface of the plug hole 111.
[0065] like Figure 1-Figure 7As shown, the first connection part 120 and the second connection part 130 are formed by copper plating on the upper, lower, left, right, front and rear surfaces of the main body 110 and the inner circumference of the insertion hole 111, and a gap is formed between the first connection part 120 and the second connection part 130 by copper plating and window opening, that is, two isolation parts 140 are formed, so that the first connection part 120 and the second connection part 130 on the surface of the main body 110 and the inner circumference of the insertion hole 111 are separated and are in a state of being independent and not connected to each other.
[0066] like Figure 1-Figure 3 As shown, the isolating portion 140 is in a strip ring shape, the portion of the isolating portion 140 located in the plug hole 111 extends along the axial direction of the plug hole 111, and the portion of the isolating portion 140 located on the surface of the main body 110 is at a radially corresponding position to the portion in the plug hole 111. That is, when looking at the main body 110 from the top and bottom of the main body 110, the two isolating portions 140 are respectively located in a radial direction of the plug hole 111, separating the first connecting portion 120 and the second connecting portion 130 into two parts with different sizes and corresponding angles. Among them, the size and corresponding angle of the second connecting portion 130 are relatively small, and the angle of the second connecting portion 130 corresponding to the axial position of the plug hole 111 from the top and bottom of the main body 110 can be 30°, 35° or 40°, so that after the plug portion 21 of the plug 20 is inserted into the plug hole 111 of the socket 100, the second connecting portion 130 is connected to at least one of the spring pieces 22 of the plug 20.
[0067] like Figure 9-11As shown, the test circuit board 200 includes a circuit board 210, a test circuit 220 and a pad 230. The test circuit 220 is arranged on the circuit board 210 and has an input terminal 221 and an output terminal 222. The pad 230 is arranged on the circuit board 210, and the pad 230 is a surface mount pad, and has a third connection portion 231 and a fourth connection portion 232. The third connection portion 231 is connected to the input terminal 221 through a copper-plated circuit on the circuit board 210, and the fourth connection portion 232 is connected to the output terminal 222 through a copper-plated circuit on the circuit board 210. The third connection portion 231 is located at a position corresponding to the first connection portion 120 of the socket 100, and the fourth connection portion 232 is located at a position corresponding to the second connection portion 130 of the socket 100. Specifically, the third connection portion 231 and the fourth connection portion 232 are in a C-shape as a whole, that is, the third connection portion 231 is in a C-shape, and the fourth connection portion 232 is located at the opening position of the C-shape. The third connection part 231 is separated from the fourth connection part 232. When the socket 100 is placed on the solder pad 230, the first connection part 120 on the socket 100 contacts the third connection part 231, and the second connection part 130 on the socket 100 contacts the fourth connection part 232. Then, soldering is performed at the position where the first connection part 120 contacts the third connection part 231 and the position where the second connection part 130 contacts the fourth connection part 232, and the socket 100 is fixed on the test circuit board 200.
[0068] When using the detection device 10, first insert the plug portion 21 of the plug 20 into the socket 111 of the socket 100. Then turn on the test circuit 220, control the current source in the test circuit 220 to output the detection current, and test the current at the same time. If the detected current value is consistent with the output detection current value, it means that the plug 20 and the socket 100 have been connected as described above. Fig.10 If the detection current cannot be measured, then the plug 20 and the socket 100 are connected as shown in (a). Fig.10 The normal connection shown in (b) is not achieved. Then, the test circuit 220 is disconnected, and the next step of operation is performed according to the test result of the detection circuit. Specifically, if the test result is normal, that is, the detected current value is consistent with the output detection current value, and the plug 20 and the socket 100 are normally connected, a power test or other test is performed. If the test result is abnormal, that is, the detection current cannot be measured, and the plug 20 and the socket 100 cannot be normally connected, the connection between the plug 20 and the socket 100 is checked, repaired or replaced.
[0069] The socket, test circuit board and detection device provided in the present application specifically configure the copper-plated circuit of the socket and the pads on the test circuit board as two separate parts, so that after the plug is inserted, it can quickly detect whether the plug and the socket are securely connected, thereby reducing the failure rate; and the use of surface-mount pads on the test circuit board instead of traditional through-hole pads is beneficial to the layout and wiring of the PCB Layout and reduces the difficulty of the PCB Layout.
