[New content] The purpose of this creation is to provide an improved probe for the above-mentioned shortcomings of the prior art. The probe does not generate electrical and signal impedance, has a simple structure and low manufacturing cost. The probe base, the probe and the sealing ring are included. The probe base comprises a sleeve, the sleeve is a hollow structure, and the hollow structure A cavity is formed in the cavity 3 M395167, and a through hole is formed in the upper end of the probe base. The lower end of the probe is slidably received in the accommodating cavity and can be stuck in the through hole, and the upper end of the probe passes through the through hole through the sleeve. Made of elastic non-conductive material, it is sleeved on the lower part of the probe and is pressed against the probe and the sleeve wall. As described above, the creative probe seals the air between the probe and the probe holder by a sealing ring. The internal pressure is isolated from the outside, and the compressibility of the air is utilized to achieve the same compression recovery characteristics of the prior art. The sealing ring is made of an elastic non-conductive material and does not generate electrical and signal impedance, so that the probe Forming a stable and good electrical connection with external electronic components, and the creation probe has a simple structure and low manufacturing cost. [Embodiment] To explain in detail the technical content, structural features, achieved goals and effects of the creation, the following examples are given. Please refer to the drawings for details. Please refer to the second to fourth figures. The creation probe includes the probe 1, the probe holder 2 and the sealing ring 3. The probe holder 2 further includes a base 21 and a sleeve. 22, the sleeve 22 in the upper part of the probe base 2 is a hollow structure, the hollow structure forms a receiving cavity 221, the upper end of the sleeve 22 is provided with a through hole 222, and the lower end of the sleeve 22 is connected to the base 21. The lower end of the probe 1 is slidably The sleeve 22 is received in the sleeve 22 of the probe holder 2 and can be caught at the through hole 222. The upper end of the probe 1 passes through the through hole 222 and exits the sleeve 22. The sealing ring 3 is sleeved on the lower part of the probe 1 and is pressed against Between the probe 1 and the wall of the sleeve 22. The upper end of the sleeve 22 is bent and extended toward the accommodating cavity 221 to form a stop portion 223, and an opening is formed in the middle of the stop portion 223. 222. In the present embodiment, the sleeve 22 of the probe may be formed by a metal material by lathe machining or by press forming. In this embodiment, the probe 1 is a metal conductive material. The lower 4 M395167 end of the probe 1 is slidably received in the accommodating cavity 221 of the sleeve 22. In detail, the lower end of the probe 1 is formed as a stopper Η, and the stopper 11 is opposite to the sleeve 22 The stop portion 223 is snap-fitted, and the probe 1 is clamped to the through hole 222. The engagement of the stop portion 223 with the stopper 11 achieves a limit action on the probe 1, thereby preventing the probe 1 from being detached during operation. Sleeve 22. An annular card slot 12 is recessed in the outer wall of the middle portion of the stopper 丨1. The sealing ring 3 is sleeved in the slot 12 and is pressed against the slot wall of the slot 12 and the wall of the sleeve 22. The lower end surface of the probe 1 is provided with a groove 13 communicating with the accommodating cavity 111, so that the compressed air is still filled when the probe 1 is pressed down to the lower end thereof to approach or contact the bottom of the accommodating cavity 221. Set the space. The lower end of the probe 1 projects outwardly to form a stop block 14 having an outer diameter larger than the outer diameter of the block 11 and slightly smaller than the inner diameter of the sleeve 22. The stopper 11 cooperates with the sleeve 22 to prevent the yaw angle of the probe 1 from being excessively moved during the up and down movement, thereby affecting the use, and increasing the working stability of the creation probe. Referring to the second to fourth figures, in the probe of the embodiment, the base 21 and the sleeve 22 are integrally formed. The base 21 is a conductive material, and the base 21 is for electrically connecting the circuit boards. The working principle of the creation probe is as follows: The sealing ring 3 is made of a resilient rubber material, which seals the air between the probe 1 and the probe holder 2, and isolates the internal pressure from the outside, and then utilizes the compressibility of the air. , the characteristics of the spring compression recovery equivalent to the prior art can be achieved. Specifically, when there is an external compressive force, the sealing ring 3 is looped in the card slot 12 on the probe 1 and is compressed between the probe 1 and the wall of the sleeve 22 to prevent leakage of air, so that the internal air naturally The compression is leak-free, and the internal air pressure is increased. When there is no external compression force, since the internal air pressure is greater than the external air pressure, the internal air pressure will return to the atmospheric pressure, so the probe 1 naturally ejects under the action of the internal air pressure. In summary, the creative probe seals the air between the probe 1 and the probe 5 M395167 by the sealing ring 3, and isolates the internal force from the outside, and then uses the compressibility of the air to achieve the same. The spring compression recovery characteristics of the prior art. The seal is made of a non-conductive rubber material that does not generate electrical and signal impedance, resulting in a stable and good electrical connection between the probe and external electronic components. Moreover, the creation probe has a simple structure and a low production cost. BRIEF DESCRIPTION OF THE DRAWINGS The first figure is a schematic view of the structure of a conventional probe.
