Further, in the above technical solution, a fixing plate is horizontally disposed at one end of the needle tube sleeve close to the sealing cover, one end of the spring is fixed on the fixing plate, and the other end of the spring is fixedly connected to the upper end of the probe rod.

The utility model has the advantages that: the utility model provides a pair of PCB circuit board detects uses probe device, simple structure has set up the safety protection region, can effectually protect the probe, improves probe device's life, makes things convenient for people's detection, is convenient for extensively promote and use.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments described in the present application, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

Fig. 1 is a schematic structural diagram of the present invention.

The reference numbers in the drawings are: 1. the probe comprises a needle tube sleeve 2, a probe rod 3, a probe head 4, a spring 5, an annular inner groove 6, a fixing plate 7 and a sealing cover.

Detailed Description

In order to make the technical problem, technical solution and advantageous effects solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to further explain the present invention in detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 shows a probe device for PCB detection, which comprises a probe tube sleeve 1, a probe rod 2 inserted into one end of the probe tube sleeve 1, a probe head 3 fixed on the end of the probe rod 2, and a sealing cover 7 threaded on the other end of the probe tube sleeve 1; the probe rod 2 is a rod-shaped structure with the diameters of two ends and the small middle diameter, and the upper end of the probe rod 2 is fixed in the needle tube sleeve 1 through a spring 4; the middle part of the needle tube sleeve 1 is provided with an annular inner groove 5, and the inner diameter of the annular inner groove 5 is smaller than the diameter of the two ends of the probe rod 2.

Wherein, the probe head 3 is fixed at the end part of the probe rod 2 by adopting a thread fixing mode. The lower end of the probe head 3 is designed to be in a conical structure, and the probe head 3 is made of alloy materials. The diameter of the middle part of the probe rod 2 is smaller than the inner diameter of the annular inner groove 5. The fixing plate 6 is horizontally arranged at one end of the needle tube sleeve 1 close to the sealing cover 4, one end of the spring 4 is fixed on the fixing plate 6, and the other end of the spring 4 is fixedly connected with the upper end of the probe rod 2.

The use principle of the probe device for detecting the PCB is as follows:

firstly, an operator can replace and maintain the probe head 3 by automatically detaching the probe head, and can replace and maintain the parts such as the spring 4 and the like by detaching the sealing cover 7 in the normal use process, so that the operation is simple and convenient; in the normal use process, after the probe head 3 touches the PCB and is compressed, the probe rod 2 rises for a distance, and when the large-diameter end of the lower end of the probe rod 2 touches the annular inner groove 5, the rising motion is stopped; when the end of the probe head 3 leaves the PCB, it will be quickly reset by the spring 4.
