Detailed Description
In order to describe the technical content and constructional features of the present invention in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.
As shown in fig. 1 to 4, the present invention provides a spring type probe 100 for electrical connection with a counterpart 300. The spring probe 100 is composed of a conductive hollow sleeve 10 and a conductive integrated spring terminal 20. The spring probe 100 is a pogpin connector, the hollow sleeve 10 is electrically connected with the first PCB board, the hollow sleeve 10 is usually mounted on the first PCB board, the spring terminal 20 is usually connected with the second PCB board in an abutting manner, specifically, the mating end 300 is disposed on the second PCB board, and the spring terminal 20 abuts against the mating end 300.
The spring probe 100 of the present invention includes only 2 parts, reduces the number of parts, and has a simpler structure. The number of parts is small, the required installation steps are small, and the assembly is simple. The hollow sleeve 10 has a mounting cavity 11. The spring terminal 20 has a mounting portion 21 mounted to the mounting cavity 11 and an abutting portion 22 exposed to the outside of the hollow sleeve 10. The mounting portion 21 and the abutting portion 22 are both compressible and elastic structures, and the abutting portion 22 can elastically abut against and electrically connect the mating end 300.
Because the mounting portion 21 and the abutting portion 22 have elasticity, when in use, the abutting portion 22 is directly elastically abutted to the mating end 300, and is contacted with the mating end 300 more stably. The abutting portion 22 is elastically compressible, and the abutting portion 22 can deform itself, for example, deform along the axial direction of the spring terminal 20, shift along the radial direction of the spring terminal 20, and even swing, so that when the first PCB vibrates, the abutting portion 22 can still stably abut against the mating end 300. Because the abutting portion 22 is elastically compressible, the abutting portion 22 can be adaptively adjusted after being skewed during use, so that the abutting portion 22 can be normally abutted with the mating end 300. The butt joint part 22 replaces the original needle shaft function and is directly abutted against the matched end 300, so that the spring terminal 20 does not need to manufacture a needle shaft, the process of manufacturing the needle shaft is omitted, the production difficulty is reduced, and the production cost is reduced. To control the resistance of the butt joint 22 within a reasonable range, the butt joint 22 is plated with a metal plating such as a copper plating, an alloy coating, a gold coating, or the like.
As shown in fig. 1 to 4, the hollow sleeve 10 restricts the mounting portion 21 in the mounting cavity 11, and the mounting portion 21 is stably mounted in the hollow sleeve 10, so that the spring terminal 20 is stably mounted. Specifically, the hollow sleeve 10 has opposite open and closed ends 12, 13. The abutting portion 22 extends out of the open end 12, a first end of the mounting portion 21 abuts against the closed end 13, the hollow sleeve 10 is formed with a stopper structure 14 at the open end 12 for restricting the extending out of the mounting portion 21, and a second end of the mounting portion 21 abuts against the stopper structure 14. The stopper structure 14 restricts the penetration of the mounting portion 21. It will be readily appreciated that the mounting portion 21 is compressed within the mounting cavity 11 to provide a pre-load to provide rigidity to the outer abutment 22 to stably abut the mating end 300. It should also be noted that when the mating portion 22 abuts against the mating end 300, both the mating portion 22 and the mounting portion 21 are compressed.
Further, the open end 12 of the hollow sleeve 10 is formed with an annular stop structure 14, the diameter of the stop structure 14 is smaller than the diameter of the mounting portion 21, and the diameter of the abutting portion 22 is smaller than the diameter of the stop structure 14. The diameter of the abutting portion 22 is smaller than that of the mounting portion 21, and since the needle shaft is eliminated, the abutting portion 22 can be made smaller irrespective of the mounting space of the needle shaft, and the abutting portion 22 can be paired with the smaller-area paired end 300. The mounting part 21 is abutted against the annular stop structure 14, so that the stress is balanced, and the mounting stability of the spring terminal 20 is ensured. Preferably, the open end 12 of the hollow sleeve 10 forms a stop 14 by means of a constriction. The spring terminal 20 of the present invention is divided into two stages, the mounting portion 21 below the stopper structure 14 and the abutting portion 22 above the stopper structure 14, but this is not a standard for distinguishing the abutting portion 22 from the mounting portion 21, and should be understood as a preferred embodiment.
As shown in fig. 1 to 4, the spring terminal 20 of the present invention is a coil spring structure made of an elongated metal conductor wound around the axis of the hollow sleeve 10. The abutting portion 22 and the mounting portion 21 are springs, and the pitch of the abutting portion 22 and the mounting portion 21 may be different, but may be the same.
Of course, the spring terminal 20 may be made in other forms, for example, as shown in fig. 7, the spring terminal 20 is a spring structure made by punching a metal conductor. Alternatively, as shown in fig. 8, the spring terminal 20 is a spring structure made by bending a metal conductor. It should be noted that, in the embodiment provided in the present invention, the hollow sleeve 10 is a cylinder, and may be manufactured by punching, sheet metal, or the like, and may be integrally formed. The hollow sleeve 10 may also be applied to square tube structures and the like.
When the spring terminal is installed, the installation part 21 of the spring terminal 20 is installed in the installation cavity 11, the opening end 12 of the hollow sleeve 10 is closed to form the stop structure 14, the stop structure 14 limits the installation part 21 in the installation cavity 11, and the abutting part 22 is exposed out of the hollow sleeve 10.
As shown in fig. 5 and 6, the spring probe 100 is protected by the protective cover 200 according to the present invention, the protective cover 200 is sleeved on the spring probe 100, and the protective cover 200 provides protection for the spring probe 100, so as to prevent the spring probe 100 from being impacted and scratched. The protective cover 200 and spring probe 100 form a connector.
When the spring probe 100 is produced, the spring probe 100 is circulated in different stations, the protective sleeve cover 200 provides protection for the spring probe 100 during circulation, and after the spring probe 100 flows into the stations, a mechanical arm and other devices take off the protective sleeve cover 200. In order to facilitate the removal of the protective cover 200, the top of the protective cover 200 is designed to be a planar structure, at this time, the top of the protective cover 200 is flat, and the manipulator can directly suck the protective cover through the suction cup, so that the pretreatment of removing the protective cover 200 is not needed to be done manually in advance.
The foregoing disclosure is only illustrative of the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
