Description

Technical Field

[0001] This utility model relates to the field of probe station technology, and in particular to a probe connection assembly that can withstand strong current and voltage. Background Technology

[0002] In the field of probe stations, with the rapid development of semiconductor devices, the demand for performance testing of devices under high current and high voltage conditions is increasing. Especially in extreme testing environments such as 500 amp high-voltage DC pulses and 3000 volt high voltages, existing probe connection assemblies face numerous challenges. On the one hand, the materials of traditional probe connection assemblies have limited conductivity and heat dissipation capabilities. When a strong current passes through, the connection points generate a large amount of heat due to contact resistance, leading to a sharp increase in local temperature. This not only accelerates material aging but also causes thermal deformation of the probe, severely affecting test accuracy and connection reliability. On the other hand, high voltage places stringent requirements on the insulation performance of the assemblies. Ordinary insulating materials are prone to electrical breakdown and partial discharge, causing test interruptions or even equipment damage, interfering with the accuracy of measurement results. Therefore, we propose a probe connection assembly that can withstand high current and voltage. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a probe connection component that can withstand strong current and voltage.

The connecting copper core includes a core seat and an end seat. A core rod is provided at one end of the core seat near the end seat. The insulating shell includes a core seat shell and an end seat shell sleeved on the outer ring of the connecting copper core. Multiple sets of annular grooves are formed on the outer rings of both the core seat shell and the end seat shell. The connector includes a male head provided at one end of the core seat shell and a female head provided at the end of the end seat shell away from the core seat shell.

[0005] Preferably, both the core seat and the end seat are hollow, the mounting end of the core rod is installed corresponding to one end of the core seat, and the outer ring of the core rod is in contact with the inner wall of the end seat.

[0007] Preferably, the end of the core housing near the end housing is tapered, and the end of the end housing near the core housing is concave. The core housing and the end housing are installed correspondingly.

[0008] Preferably, the insulating shell is hollow and made of engineering plastic with high insulation performance, and the outer wall of the connecting copper core is in contact with the inner wall of the insulating shell.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] This invention features a simple overall structure. The copper core effectively reduces the contact resistance at the probe connection point, minimizing heat generation during high-current flow, thus improving measurement accuracy and the reliability of the connection components. It also rapidly dissipates heat generated under high-current and high-voltage conditions, preventing overheating and extending the device's lifespan.

Detailed Implementation

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example

[0019] like Figure 1-3 As shown, the probe connection assembly withstanding high current and voltage proposed in this utility model includes a connecting copper core 1, an insulating shell 2, and a connector 3. The structure is simple due to the mutual cooperation of the connecting copper core 1, the insulating shell 2, and the connector 3.

[0020] The connecting copper core 1 includes a core seat 11 and an end seat 12. The connecting copper core 1 is made of copper-tungsten alloy and its surface is treated with a silver plating coating. Both the core seat 11 and the end seat 12 are hollow. A core rod 13 is provided on one end of the core seat 11 near the end seat 12. The mounting end of the core rod 13 is installed correspondingly to one end of the core seat 11 and is fixedly connected to one end of the core seat 11. The outer ring of the core rod 13 fits against the inner wall of the end seat 12, and the outer side of the core rod 13 is fixedly connected to the inner wall of the end seat 12. The setting of the core rod 13 can reduce the contact current at the probe connection point. The core seat 11 and the end seat 12 are provided with connecting grooves 14 at their far ends. The connecting grooves 14 can better allow the probe to be inserted into the core seat 11 and the end seat 12. Multiple sets of heat dissipation holes 15 are provided on the core seat 11 and the end seat 12. The heat dissipation holes 15 can quickly dissipate the heat generated under high current and voltage conditions, prevent the connection part from overheating, and extend the service life of the device. The copper core 1 effectively reduces the contact resistance of the probe connection part, reduces the heat generated when a strong current passes through, and improves the measurement accuracy and the reliability of the connection components.

[0021] The insulating shell 2 includes a core seat shell 21 and an end seat shell 22 fitted onto the outer ring of the connecting copper core 1. The insulating shell 2 is hollow and made of high-insulation engineering plastic. The high-insulation engineering plastic insulating shell 2 can effectively isolate high voltage. The outer wall of the connecting copper core 1 and the inner wall of the insulating shell 2 are fitted together, and the insulating shell 2 is fixedly connected to the connecting copper core 1. The end of the core seat shell 21 near the end seat shell 22 is conical, and the end of the end seat shell 22 near the conical end of the core seat shell 21 is concave. The core housing 21 is installed corresponding to the end housing 22. The ends of the core housing 21 and the end housing 22 are tightly fitted together. The split design of the insulating housing 2 can better dissipate the heat dissipated from the connecting copper core 1. Multiple sets of annular grooves 23 are opened on the outer ring of both the core housing 21 and the end housing 22. The annular grooves 23 can increase the external friction of the connecting components, making it easier for the operator to handle and assemble. The insulating housing 2 can effectively isolate high voltage, avoid leakage, flashover and other phenomena, and ensure the safety of the operator and the accuracy of the measurement results.

[0022] The connector 3 includes a male connector 31 located at one end of the core housing 21. Both the core housing 21 and the end housing 22, located away from each other, have slots on their inner rings. The mounting end of the male connector 31 is installed corresponding to the slot on the core housing 21, and the male connector 31 and the core housing 21 are interlocked. A female connector 32 is located at the end of the end housing 22 away from the core housing 21. The mounting end of the female connector 32 is installed corresponding to the slot on the end housing 22, and the female connector 32 and the end housing 22 are interlocked. Both the male connector 31 and the female connector 32 have connecting pin holes 33 located at their axial positions. The design facilitates probe insertion. The connecting pin hole 33 corresponds to the hollow positions on the core seat 11 and the end seat 12. When the connector 3 is in the assembled state, the mounting end of the male connector 31 is tightly fitted with the end of the end seat 12 near the connecting groove 14, and the mounting end of the female connector 32 is tightly fitted with the end of the core seat 11 near the connecting groove 14. The interlocking assembly of the connector 3 and the insulating shell 2 can adapt to certain vibrations and displacements, so that the device can maintain a stable connection between the probe and the circuit under test when subjected to external vibrations or impacts, ensuring the continuity of measurement and the accuracy of data.

[0023] In this embodiment, the operator first assembles the core seat 11 and the end seat 12 accordingly. At this time, the outer periphery of the connecting groove 14 at one end of the core seat 11 is fitted and fixed to the inner wall of the insulating shell 2. Then, the operator fixes the insulating shell 2 on the outside of the connecting copper core 1. At this time, the inner wall of the core seat shell 21 is fitted and fixed to the outer periphery of the core seat 11, and the inner wall of the end seat shell 22 is fitted and fixed to the outer periphery of the end seat 12. Finally, the male head 31 is fitted and assembled to the corresponding slot at one end of the core seat shell 21, and the female head 32 is fitted and assembled to the corresponding slot at one end of the end seat shell 22, thereby completing the assembly operation of this device.

[0024] In use, the probe is inserted into the core seat 11 and the end seat 12 through the connecting pin hole 33. The head of the probe to be tested is in close contact with the top of the core rod 13. Under strong current and voltage conditions, the heat generated is dissipated through the heat dissipation hole 15 and then evaporated into the outside air through the split insulating shell 2 for rapid heat dissipation. At this time, the insulating shell 2 can effectively isolate high voltage and prevent leakage and other phenomena, ensuring the safety and accuracy of the measurement work.
