Technical Field
[0001] This utility model relates to the field of circuit board testing technology, and in particular to a multi-channel PCBA circuit node continuity testing device. Background Technology
[0002] PCBA stands for Printed Circuit Board Assembly, a core component of electronic products. In PCBA circuits, a circuit node refers to the connection point of two or more circuit elements. A continuity testing device is an instrument specifically used to test whether a continuous conductive path can be formed between two points in a circuit. Multi-channel means that the testing device can operate on multiple independent signal paths or test points simultaneously.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the disassembly of the detector body usually requires workers to use disassembly tools to remove the screws on the detector body one by one. The disassembly operation is cumbersome and takes a lot of time. Therefore, in order to solve the above problems, a multi-channel PCBA circuit node continuity testing device is proposed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where the disassembly of the detector body by staff is cumbersome and time-consuming, and to propose a multi-channel PCBA circuit node continuity testing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-channel PCBA circuit node continuity testing device, comprising a detector body, a detector front end mounted on the surface of the detector body, a connection port on the surface of the detector front end, and adjustment devices on both sides of the detector front end. Each adjustment device includes two mounting blocks, which are respectively fixedly connected to both sides of the detector front end. A connecting rod is fixedly connected to the surface of each mounting block, and a slot is formed on one side of each connecting rod. Fixing blocks are fixedly connected to both sides of the detector body, and circular grooves are formed on the surface of each fixing block. The connecting rod is slidably connected to the inner surface of the circular groove of the fixing block. A connecting block is fixedly connected to the upper surface of the detector body, and long rods are fixedly connected to both sides of each connecting block. An L-shaped block is slidably connected to the arc surface of each long rod, and a round rod is fixedly connected to the surface of the L-shaped block. The round rod is slidably connected to the inner surface of the connecting rod slot. A first spring is sleeved on the arc surface of the long rod, and both ends of the first spring are fixedly connected to the connecting block and the L-shaped block, respectively.
[0006] The effect achieved by the above-mentioned components is as follows: by setting up the adjustment device, it is possible to facilitate the disassembly and maintenance of the detector body by the staff. This avoids the situation where the traditional disassembly requires the staff to use disassembly tools to remove the screws on the detector body one by one, which is a complicated operation that takes a lot of time. This improves the convenience of the device.
[0007] Preferably, a pull rod is fixedly connected to the surface of the L-shaped block, and the size of the round rod is adapted to the size of the connecting rod slot.
[0008] The aforementioned components achieve the following effect: they facilitate workers in easily releasing the fixing of the connecting rods on both sides at once, thus improving the flexibility of the device.
[0009] Preferably, a guide block is fixedly connected to the surface of the fixing block, and the connecting rod is slidably connected to the arc surface of the guide block.
[0010] The effect achieved by the above components is that the addition of the guide block allows the operator to quickly align the connecting rod with the groove of the fixing block, reducing the time required for the operator to slowly align the groove of the fixing block.
[0011] Preferably, one end of the connecting rod and the round rod is spherical.
[0012] The effect achieved by the above components is that one end of both the connecting rod and the round rod is spherical, which makes it easier for the connecting rod to be inserted into the inner surface of the circular groove of the fixing block, and at the same time, it also makes it easier for the round rod to be inserted into the inner surface of the connecting rod slot.
[0013] Preferably, the front surface of the detector is provided with an auxiliary device, the auxiliary device including a fixing frame, the fixing frame being fixedly connected to the front surface of the detector, a slider being slidably connected to the inner surface of the fixing frame, a protective plate being fixedly connected to the upper surface of the slider, a slot being provided on one side of the protective plate, an arc-shaped block being fixedly connected to one side of the fixing frame, a rod being slidably inserted into the arc-shaped block, the rod being slidably connected to the inner surface of the slot, and a round block being fixedly connected to one end of the rod.
[0014] The aforementioned components achieve the following effects: by setting up auxiliary devices, the connection port is protected, preventing the metal parts or pins at the connection port from being impacted or squeezed by external forces. At the same time, since the connection port is exposed to the outside environment for a long time, dust may form an insulating layer inside the connection port, thereby affecting the conductivity of the connection and improving the safety of the device.
[0015] Preferably, the arc surface of the insertion rod is fitted with a second spring, and the two ends of the second spring are fixedly connected to the arc block and the round block, respectively.
[0016] The effect achieved by the above components is that when the insertion rod is aligned with the slot, the elastic force of the second spring will cause the insertion rod to automatically insert into the inner surface of the slot.
[0017] Preferably, a limiting groove is provided on one side of the protective plate, and the size of the limiting groove is adapted to the size of the insertion rod.
[0018] The effect achieved by the above components is to fix the protective plate after it is opened, thus preventing the protective plate from sliding down the fixing frame and affecting the use of the connection port.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, by setting an adjustment device, the disassembly and maintenance of the detector body by the staff is made easier.

This improves the convenience of the device.
[0021] 2. In this utility model, by setting an auxiliary device, the connection port is protected, preventing the metal parts or pins at the connection port from being impacted or squeezed by external forces. At the same time, since the connection port is exposed to the outside world for a long time, dust may form an insulating layer inside the connection port, thereby affecting the conductivity of the connection and improving the safety of the device.

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: a multi-channel PCBA circuit node continuity testing device, including a detector body 1, a detector front end 2 mounted on the surface of the detector body 1, a connection port 5 on the surface of the detector front end 2, and adjustment devices 3 on both sides of the detector front end 2. By setting the adjustment devices 3, the device facilitates the disassembly and maintenance of the detector body 1 by the staff, avoiding the cumbersome and time-consuming process of disassembling the detector body 1 by the staff using disassembly tools. The device improves the convenience of the device. An auxiliary device 4 is set on the surface of the detector front end 2 to protect the connection port 5, preventing the metal parts or pins at the connection port 5 from being impacted or squeezed by external forces. At the same time, since the connection port 5 is exposed to the outside environment for a long time, dust may form an insulating layer inside the connection port 5, thereby affecting the continuity performance of the connection, thus improving the safety of the device.
[0031] The specific settings and functions of its adjustment device 3 and auxiliary device 4 will be described in detail below.
[0032] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the adjusting device 3 includes two mounting blocks 301, which are fixedly connected to both sides of the front end 2 of the detector respectively. A connecting rod 302 is fixedly connected to the surface of the mounting block 301, and a slot is provided on one side of the connecting rod 302. Fixing blocks 303 are fixedly connected to both sides of the detector body 1, and circular grooves are provided on the surface of the fixing blocks 303. The connecting rod 302 is slidably connected to the inner surface of the circular groove of the fixing block 303. A connecting block 304 is fixedly connected to the upper surface of the detector body 1. Long rods 305 are fixedly connected to both sides of the connecting block 304. An L-shaped block 306 is slidably connected to the arc surface of the long rod 305. A round rod 307 is fixedly connected to the surface of the L-shaped block 306, and the round rod 307 is slidably connected to the inner surface of the slot of the connecting rod 302. A first spring 308 is sleeved on the arc surface of the long rod 305, and the two ends of the first spring 308 are respectively connected to the connecting block 304. The L-shaped block 306 is fixedly connected to the L-shaped block 306, and a pull rod 309 is fixedly connected to the surface of the L-shaped block 306. The size of the round rod 307 is adapted to the size of the slot of the connecting rod 302, which makes it easy for the staff to release the fixing of the two connecting rods 302 at one time, improving the flexibility of the device. A guide block 310 is fixedly connected to the surface of the fixing block 303. The connecting rod 302 is slidably connected to the arc surface of the guide block 310. The addition of the guide block 310 allows the staff to quickly align the connecting rod 302 with the round slot of the fixing block 303, reducing the operation time required for the staff to slowly align the round slot of the fixing block 303. One end of the connecting rod 302 and the round rod 307 are spherical. The spherical shape of one end of the connecting rod 302 and the round rod 307 makes it easier for the connecting rod 302 to be inserted into the inner surface of the round slot of the fixing block 303, and also makes it easier for the round rod 307 to be inserted into the inner surface of the slot of the connecting rod 302.
[0033] Reference Figure 5 , Figure 6 and Figure 7 As shown, specifically, the auxiliary device 4 includes a fixing frame 41, which is fixedly connected to the surface of the detector front end 2. A slider 42 is slidably connected to the inner surface of the fixing frame 41, and a protective plate 43 is fixedly connected to the upper surface of the slider 42. A slot 44 is provided on one side of the protective plate 43, and an arc-shaped block 45 is fixedly connected to one side of the fixing frame 41. A rod 46 is slidably inserted into the arc-shaped block 45, and the rod 46 is slidably connected to the inner surface of the slot 44. A circular block 47 is fixedly connected to one end of the rod 46, and the arc of the rod 46... The cover is fitted with a second spring 48, the two ends of which are fixedly connected to the arc-shaped block 45 and the round block 47 respectively. When the insertion rod 46 is aligned with the slot 44, the elastic force of the second spring 48 will drive the insertion rod 46 to automatically insert into the inner surface of the slot 44. A limiting groove 49 is opened on one side of the protective plate 43. The size of the limiting groove 49 is adapted to the size of the insertion rod 46, which achieves the effect of fixing the protective plate 43 after it is opened, and prevents the protective plate 43 from sliding down the fixing frame 41 and affecting the use of the connection port 5.
[0034] Working principle: When staff need to inspect the interior of the detector body 1, they can use two fingers to push the pull rod 309 towards each other. During this pushing process, the pull rod 309 will cause the L-shaped block 306 to move, which in turn causes the round rod 307 to move until the round rod 307 moves away from the inner surface of the slot of the connecting rod 302. At this point, the front end 2 of the detector can be pushed, thereby moving the mounting block 301. The mounting block 301 will then move the connecting rod 302. By setting the adjustment device 3, the device facilitates the disassembly and maintenance of the detector body 1, avoiding the cumbersome and time-consuming process of traditional disassembly methods that require staff to remove each screw from the detector body 1 using tools. This improves the convenience of the device.
[0035] When the staff needs to protect the connection port 5, they pull the round block 47 to move the insertion rod 46 backward on the inner surface of the limiting groove 49 until the insertion rod 46 is away from the inner surface of the limiting groove 49. At this time, they push the protective plate 43 to move the slider 42 downward on the inner surface of the fixing frame 41 until the insertion rod 46 is aligned with the slot 44. The elastic force of the second spring 48 will cause the insertion rod 46 to automatically insert into the inner surface of the slot 44. By setting the auxiliary device 4, the connection port 5 is protected, preventing the metal parts or pins at the connection port 5 from being impacted or squeezed by external forces. At the same time, since the connection port 5 is exposed to the outside for a long time, dust may form an insulating layer inside the connection port 5, thereby affecting the conductivity of the connection and improving the safety of the device.
