Description

Technical Field

[0001] The utility model relates to the technical field of electrical detection, in particular to a detection head structure of a detection device. Background Art

[0002] In the production process of electronic devices, there is an important link, which is to detect the conductive and signal transmission states of the electronic devices after assembly. This link is to ensure that all components of the electronic device meet the product specification requirements after assembly and avoid affecting the state of the terminal product due to various possible factors.

[0003] In the electrical detection operation, different electrical detection devices are selected according to different detection objects. Currently, the main component for detection is an electrical test pin. The electrical test pin contacts the object to be tested to obtain the electrical or signal conduction state of the object to be tested. Generally, the electrical test pins are installed on the base according to the distribution state of the electrical contacts of the object to be tested, and each electrical test pin has a joint for contacting the object to be tested and conducting electricity. During detection, the base moves towards the object to be tested so that the joints of the electrical test pins contact the electrical contacts of the object to be tested and conduct electricity with them to detect whether the object to be tested meets the required electrical state.

[0004] Currently, the joints of electrical test pins are processed by turning to form the required structures according to different types of objects to be tested. Therefore, they have a relatively high manufacturing cost and require more manufacturing time.

[0005] In view of this, the applicant conceived and proposed a modular electrical detection head to effectively reduce the product cost and improve the convenience of replacement. Summary of the Utility Model

[0006] The main purpose of the utility model is to propose a detection head structure of a detection device, aiming to solve the problems put forward in the above background art.

[0007] To achieve the above purpose, the utility model proposes a detection head structure of a detection device, including a metal part with an overall T shape. The lower part of the metal part has opposite sides extending outwards to form extension parts that are staggeredly opposite to the upper part of the metal part. The bottom wall of the metal part and the bottom walls of the extension parts are formed by a number of cone parts for contacting the object to be tested evenly distributed. A gold plating layer is formed on the surface of the cone parts by electroplating.

[0008] The technical solution of the present utility model provides two extension parts at the lower part of a T-shaped metal part, so that the upper and lower parts of the metal part are staggered relative to each other. A number of cone parts for contacting the object to be measured are evenly distributed on the bottom wall of the metal part, and a gold plating layer is formed on the surface of the cone parts by electroplating. Compared with the traditional electrical test probe connector, the integrally formed metal part improves the convenience of replacement, reduces the manufacturing time, and thus reduces the manufacturing cost. During testing, electricity is conducted through the tip position of the cone part, and the gold plating layer on the surface has high reliability, conductivity and stability.
