Abstract
Description
Technical Field
[0001] This utility model relates to the field of oscilloscope probe technology, and in particular to a connector and an oscilloscope probe. Background Technology
[0002] To test a signal, an oscilloscope must introduce the signal through an oscilloscope probe. Probes are divided into passive probes and active probes. Active probes are more convenient than passive probes, but the internal functional modules of active probes require power. Therefore, most existing oscilloscopes have a built-in power supply structure, which can be connected to the oscilloscope probe connector to power the internal functional modules of the active probe.
[0003] Because there are many oscilloscope manufacturers, the power supply structure for oscilloscope probes varies among different brands and models. As a result, the probes that are compatible with these oscilloscopes are all dedicated probes with very poor versatility. If you have multiple different oscilloscopes, you usually need to equip them with multiple corresponding oscilloscope probes, which makes the purchase cost of oscilloscope probes relatively high.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0041] This utility model embodiment provides a connector 1000, such as Figures 1-5As shown, connector 1000 includes a base 100, a core socket 200, and an expansion socket 300. The base 100 houses a functional module 110, and a first electrical connection structure 120 electrically connected to the functional module 110 is provided on the base 100. The core socket 200 is disposed on the base 100 and electrically connected to the functional module 110; the core socket 200 is used to transmit signals to an oscilloscope. The expansion socket 300 is detachably connected to the base 100, and a second electrical connection structure 310 is provided on the expansion socket 300. The second electrical connection structure 310 is electrically connected to the first electrical connection structure 120 and is used to electrically connect to a power supply structure on a pre-set oscilloscope.
[0042] Specifically, the connector 1000 in this embodiment includes an expansion socket 300 and a base 100. Since the functional module 110 and the core socket 200 are disposed on the base 100, and the second electrical connection structure 310, which is electrically connected to the power supply structure of the oscilloscope, is disposed on the expansion socket 300, and since the expansion socket 300 and the base 100 are detachably connected, the connector 1000 can be adapted to different oscilloscopes by replacing different expansion sockets 300. It has high versatility and is more cost-effective than the prior art of replacing the entire oscilloscope probe.
[0043] It should be noted that there are many specific implementations of the first electrical connection structure 120, such as the first electrical connection structure 120 being a pin header, a female header, a TYPE-C female connector, a TYPE-C male connector, etc., which are not limited in this embodiment; there are also many specific implementations of the second electrical connection structure 310, such as the second electrical connection structure 310 being a pin header, a female header, a spring pin, a TYPE-C female connector, a TYPE-C male connector, etc., which are not limited in this embodiment.
[0044] refer to Figures 1-5 In a specific embodiment, the base 100 includes a first surface 130, the core base 200 is exposed on the first surface 130, the extension base 300 is detachably mounted on the first surface 130, and the extension base 300 is also provided with a third electrical connection structure 320. The second electrical connection structure 310 is electrically connected to the third electrical connection structure 320. The third electrical connection structure 320 is disposed on the side of the extension base 300 facing the first surface 130, and the first electrical connection structure 120 is exposed on the first surface 130 to cooperate with the third electrical connection structure 320.
[0045] Specifically, since the core base 200 is exposed on the first surface 130, the expansion base 300 also needs to be detachably installed on the first surface 130. Based on this, in this embodiment, the third electrical connection structure 320 is disposed on the side of the expansion base 300 facing the first surface 130, and the first electrical connection structure 120 is exposed on the first surface 130. This makes it most convenient for the third electrical connection structure 320 to be electrically connected to the first electrical connection structure 120.
[0046] refer to Figures 1-5 In some embodiments, the base 100 is provided with a through hole 140 communicating with its interior, the extension base 300 is provided with a pin 330, and the base 100 is provided with a vase terminal 150 facing the through hole 140. When the extension base 300 is connected to the base 100, the pin 330 passes through the through hole 140 and the vase terminal 150.
[0047] By implementing this embodiment, when the expansion base 300 needs to be installed, simply insert the pin 330 into the through hole 140, and the vase terminal 150 can clamp the pin 330 to fix the expansion base 300 and prevent the expansion base 300 from falling off the base 100. When the expansion base 300 needs to be disassembled, simply pull out the expansion base 300, which is very convenient.
[0048] refer to Figures 1-5 In some embodiments, a plurality of through holes 140 are provided, and the plurality of through holes 140 are evenly distributed in the circumferential direction of the rotating ring 500. A plurality of vase terminals 150 and pins 330 are correspondingly provided. This arrangement can increase the connection stability between the extension base 300 and the base 100.
[0049] refer to Figure 1 , Figures 7-9 In some embodiments, the connector 1000 further includes a retaining ring 400 and a rotating ring 500. The retaining ring 400 is mounted on the base 100, and the core seat 200 is disposed inside the retaining ring 400 and spaced apart from the retaining ring 400. The retaining ring 400 includes a retaining ring 500 in its axial direction. Figure 8 The first end 410 and the second end 420 are arranged opposite to each other in the X direction of the oscilloscope. The first end 410 has four receiving grooves 430 extending toward the second end 420. The four receiving grooves 430 are evenly distributed in the circumferential direction of the fixing ring 400. The receiving grooves 430 connect the inner side wall and the outer side wall of the fixing ring 400. The receiving groove 430 includes a first receiving area 431 and a second receiving area 432 that are adjacent to each other in the circumferential direction of the fixing ring 400. A slot 440 is provided on the bottom of the receiving groove 430. The slot 440 is adjacent to the second receiving area 432. The slot 440 is used to accommodate the locking block 9000 on the socket of the oscilloscope. The rotating ring 500 is sleeved on the outside of the fixed ring 400. Four limiting blocks 510 are provided on the inner side wall of the rotating ring 500. The four limiting blocks 510 are evenly distributed in the circumferential direction of the rotating ring 500. The rotating ring 500 is rotatably connected to the base 100 so that the limiting blocks 510 can switch between the first accommodating area 431 and the second accommodating area 432.
[0050] When the connector 1000 used in this embodiment is connected to the oscilloscope, the two locking blocks 9000 on the oscilloscope will first enter the second receiving area 432 of the two receiving slots 430, and then enter the slot 440 that communicates with the two second receiving areas 432. After the locking blocks 9000 enter the slot 440, the second receiving area 432 is not occupied. In this way, the limiting block 510 can be moved to the second receiving area 432 by rotating the rotating ring 500. At this time, the slot opening of the slot 440 will be blocked by the limiting block 510, and the connector 1000 can be fixed to the socket, effectively preventing the connector 1000 from becoming loose from the socket.
[0051] Specifically, existing oscilloscopes will have a socket for connector 1000 to be connected, such as Figure 6 As shown, these sockets have two protruding locking blocks 9000 on their outer sides. In the prior art, the two locking blocks 9000 of some oscilloscopes are arranged opposite each other in the horizontal direction, while the two locking blocks 9000 of other oscilloscopes are arranged opposite each other in the direction of gravity. Since the first end 410 in this embodiment has four receiving slots 430 extending toward the second end 420, and the four receiving slots 430 are evenly distributed in the circumferential direction of the fixing ring 400, when the connector 1000 is actually used, two of the receiving slots 430 are arranged horizontally, and the other two receiving slots 430 are arranged vertically. This allows the connector 1000 to be compatible with sockets where the two locking blocks 9000 are arranged horizontally, as well as sockets where the two locking blocks 9000 are arranged vertically.
[0052] refer to Figure 7 In a specific embodiment, the connector 1000 further includes an elastic element 600, which is connected to the rotating ring 500 and is used to deform and store energy when the limiting block 510 is accommodated in the first accommodating region 431, and to drive the limiting block 510 to move to the second accommodating region 432 when releasing energy.
[0053] By implementing this embodiment, after the card block 9000 enters the card slot 440, the elastic element 600 releases energy to drive the limiting block 510 to move to the second receiving area 432, without the need to manually rotate the rotating ring 500, which is very convenient.
[0054] There are many specific implementations of the elastic element 600, and this embodiment is not limited to it. The following three specific embodiments are listed for reference.
[0055] In the first specific embodiment, the elastic element 600 is a tension spring. The base 100 has a structure for connecting to one end of the tension spring, and the rotating ring 500 has a connecting part for connecting to the other end of the tension spring. As long as the rotating ring 500 rotates so that the limiting block 510 moves from the second accommodating region 432 to the first accommodating region 431, the connecting part moves away from the structure connected to one end of the tension spring, so that the tension spring can deform and store energy. In this way, when the tension spring releases energy, it can drive the limiting block 510 to move from the first accommodating region 431 to the second accommodating region 432.
[0056] refer to Figure 7 In the second specific embodiment, the elastic element 600 is a compression spring. The base 100 has a structure for connecting to one end of the compression spring, and the rotating ring 500 has a connecting part that connects to the other end of the compression spring. As long as the rotating seat rotates so that the limiting block 510 moves from the second accommodating region 432 to the first accommodating region 431, the connecting part approaches the structure connected to one end of the compression spring, which allows the compression deformation to store energy. In this way, when the stretching spring releases energy, it can drive the limiting block 510 to move from the first accommodating region 431 to the second accommodating region 432.
[0057] In the third specific embodiment, the elastic element 600 is a torsion spring. One end of the torsion spring is connected to the base 100, and the other end is connected to the rotating ring 500. Since the rotating ring 500 can rotate relative to the base 100, the torsion spring can be configured to deform and store energy when the limiting block 510 is accommodated in the first accommodating region 431, and to drive the limiting block 510 to move to the second accommodating region 432 when releasing energy.
[0058] refer to Figures 7-9 In some embodiments, the side of the limiting block 510 facing away from the second end 420 is a slope 511, and the slope 511 tends to approach the second end 420 in the direction of the first receiving region 431 near the second receiving region 432.
[0059] Specifically, when the elastic element 600 releases energy, the limiting block 510 will be located in the second receiving area 432, blocking the opening of the slot 440. At this time, the oscilloscope's locking block 9000 will be restricted by the limiting block 510 and unable to enter the slot 440. Only by first rotating the rotating ring 500 to move the limiting block 510 from the second receiving area 432 to the first receiving area 431 can the locking block 9000 smoothly enter the slot 440. The advantage of setting the inclined surface 511 is that there is no need to manually rotate the rotating ring 500. It is only necessary to use the inclined surface 511 to press the locking block 9000 in the oscilloscope, and the rotating ring 500 will rotate under the cooperation of the inclined surface 511 and the locking block 9000, thereby allowing the locking block 9000 to smoothly enter the slot 440. It can be seen that implementing this embodiment only requires one-handed operation to connect the connector 1000 to the oscilloscope socket, which is very convenient.
[0060] In some embodiments, the side of the limiting block 510 facing away from the second end 420 is an arc surface, and in the direction of the first receiving region 431 near the second receiving region 432, the arc surface tends to approach the second end 420.
[0061] Specifically, when the elastic element 600 releases energy, the limiting block 510 will be located in the second receiving area 432, blocking the opening of the slot 440. At this time, the oscilloscope's locking block 9000 will be restricted by the limiting block 510 and unable to enter the slot 440. Only by first rotating the rotating ring 500, causing the limiting block 510 to move from the second receiving area 432 to the first receiving area 431, can the locking block 9000 smoothly enter the slot 440. The advantage of setting the curved surface is that there is no need to manually rotate the rotating ring 500. It is only necessary to use the curved surface to press the locking block 9000 in the oscilloscope, and the rotating ring 500 will rotate under the cooperation of the curved surface and the locking block 9000, thereby allowing the locking block 9000 to smoothly enter the slot 440. It can be seen that implementing this embodiment only requires one-handed operation to connect the connector 1000 to the oscilloscope socket, which is very convenient.
[0062] refer to Figure 1 , Figure 7 In some embodiments, the base 100 includes a first surface 130 and a second surface 160 adjacent to the first surface 130. The fixed ring 400, the rotating ring 500 and the core seat 200 are all exposed on the first surface 130. The second surface 160 is provided with a through-hole 161. The rotating ring 500 is connected to an operating handle 520, which passes through the through-hole 161.
[0063] Specifically, when removing connector 1000 from the oscilloscope, simply hold the base 100 with one hand, then use your finger to turn the operating handle 520 to rotate the rotating ring 500. This will move the limiting block 510 from the second receiving area 432 to the first receiving area 431. At this point, the limiting block 510 is no longer blocking the slot of the slot 440, and connector 1000 can be pulled out directly. Therefore, by implementing this embodiment, connector 1000 can be easily removed from the oscilloscope with just one hand.
[0064] refer to Figure 7 In a specific embodiment, the operating handle 520 and the rotating ring 500 are integrally formed, which can reduce the number of parts, thereby reducing mold opening costs, assembly costs, and production costs.
[0065] refer to Figure 7In some embodiments, the functional module 110 includes an attenuation ratio adjustment module. A spring pin 700 is mounted on the rotating ring 500. The spring pin 700 is electrically connected to the attenuation ratio adjustment module. The spring pin 700 protrudes from the side of the rotating ring 500 facing away from the second end 420. The spring pin 700 is used to contact the attenuation ratio setting ring on the oscilloscope to adjust the attenuation ratio of the oscilloscope probe.
[0066] Specifically, some oscilloscopes have an attenuation ratio setting ring surrounding the socket, which can be used to adjust the attenuation ratio of the oscilloscope probe. To make connector 1000 compatible with such oscilloscopes, in this embodiment, functional module 110 includes an attenuation ratio adjustment module. A spring pin 700 is mounted on a rotating ring 500, electrically connected to the attenuation ratio adjustment module. The spring pin 700 protrudes from the side of the rotating ring 500 facing away from the second end 420, allowing it to contact the attenuation ratio setting ring on the oscilloscope, thereby adjusting the attenuation ratio of the oscilloscope probe.
[0067] refer to Figure 10 In some embodiments, a power socket 170 is installed on the base 100, and the power socket 170 is electrically connected to the functional module 110.
[0068] Specifically, if the oscilloscope probe is not connected to an external power source, only passive probes can be used. Providing power to the oscilloscope probe expands its applicability to active probes, thereby improving the ease of use. In this embodiment, a power socket 170 is installed on the base 100. The purpose of this is to provide power to the oscilloscope probe using an external power source when the expansion socket 300 cannot be used or a suitable expansion socket 300 is not available, thus improving the ease of use of the probe.
[0069] There are many specific implementations of the power socket 170, such as TYPE-C female socket, Micro USB female socket, etc., and this embodiment is not limited to them.
[0070] This utility model embodiment also provides an oscilloscope probe, such as Figures 1-5 As shown, the oscilloscope probe includes the connector 1000 illustrated in the above embodiment. The connector 1000 includes a base 100, a core mount 200, and an expansion mount 300. The base 100 houses a functional module 110, and a first electrical connection structure 120 electrically connected to the functional module 110 is provided on the base 100. The core mount 200 is disposed on the base 100 and electrically connected to the functional module 110; the core mount 200 is used to transmit signals to the oscilloscope. The expansion mount 300 is detachably connected to the base 100, and a second electrical connection structure 310 is provided on the expansion mount 300. The second electrical connection structure 310 is electrically connected to the first electrical connection structure 120 and is used to electrically connect to a power supply structure on a pre-defined oscilloscope.
[0071] Specifically, the connector 1000 in this embodiment includes an expansion socket 300 and a base 100. Since the functional module 110 and the core socket 200 are disposed on the base 100, and the second electrical connection structure 310, which is electrically connected to the power supply structure of the oscilloscope, is disposed on the expansion socket 300, and since the expansion socket 300 and the base 100 are detachably connected, the connector 1000 can be adapted to different oscilloscopes by replacing different expansion sockets 300. It has high versatility and is more cost-effective than the prior art of replacing the entire oscilloscope probe.
