Technical Field

The invention relates to the field of magnetic control inductive switches, in particular to a clamping type terminal structure.

Background

The existing magnetic control inductive switch is generally manufactured by welding wires on pins at two ends of a reed switch, and then inserting a protective rubber box body for packaging. The dry reed pipe is formed by fusing and fixing a reed and an extremely thin glass pipe, and the interior of the dry reed pipe is filled with inert gas, so that the dry reed pipe is extremely sensitive to temperature. Therefore, the production must be specially controlled for the skill of the operator, the temperature of the welding process, the welding time, and the like, and is difficult to control practically. Because the two different materials have different heat conductivity coefficients and expansion and contraction coefficients, irreversible cracking and other damages are easily caused on the adhesion part of the reed and the glass after the high-temperature heat conduction of the soldering iron, and the damages are difficult to judge and identify in short-term use and by naked eyes.

Therefore, the structure introduces a special clamping terminal for use, avoids the influence of damage caused by sudden temperature change of a reed switch in the magnetic control switch, and ensures simpler processing and more reliable performance.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

According to the description of fig. 1-4:

a snap-in terminal structure comprising:

the shell 1 comprises a shell connecting hole 11 and a reed pipe placing hole 12 which are arranged from front to back;

the reed pipe mechanism 2 is arranged in the reed pipe placing hole 12 and comprises a reed pipe 21, a lead 22 and a clamping terminal 23, the clamping terminal 23 is arranged at the left end and the right end of the reed pipe 21 in an up-down mirror mode and comprises a riveting head 231 and a terminal clamping interface 232 which are arranged from front to back respectively, the reed pipe 21 comprises pins 211 which are arranged at the two ends respectively, and the lead 22 is riveted in the riveting head 231 respectively.

Because the diameter of the pin 211 is larger than that of the terminal card interface 232, the pins 211 are respectively arranged in the terminal card interface 232, the terminal card interface 232 comprises a guiding bevel edge 2321 arranged from outside to inside, and the guiding bevel edge 2321 is inclined from outside to inside, when a user uses the invention, the clamping connection between the pin 211 and the clamping terminal 23 can be ensured to be tighter through the inclined arrangement of the guiding bevel edge 2321 and the arrangement of the diameter of the card interface, and the pin 211 can be clamped into the terminal more accurately when being guided.

Because the material of the clamping terminal 23 is copper alloy, when a user uses the invention, the clamping terminal 23 is made of copper alloy, which can ensure the conductivity, and meanwhile, the pin 211 of the reed switch 21 is tightly contacted with the terminal clamping interface 232.

Because the left end of the shell 1 is closed, the phenomenon that the reed switch mechanism 2 deviates to the outside position after being arranged in the shell 1 is prevented, and therefore normal use of a user is influenced.

When a user uses the invention, the tight connection between the invention and external equipment can be realized through the use of the shell connecting hole 11 and the connection of the connecting hole and the locking bolt.

The conducting wire 22 is connected to the conducting wire 22 through the reed pipe 21 at the connecting terminal 23.

When a user uses the invention, the pins 211 of the reed pipe 21 are respectively positioned and clamped into the terminal clamping interfaces 232 of the clamping terminals 23, the terminal clamping interfaces 23 and the pins 211 are in interference fit with each other, so that the accurate installation and positioning of the reed pipe 21 in the clamping terminals 23 are ensured, and the use of the lead 22 is matched, so that the invention is normally conductive, the clamping terminals 23 are independently crimped on the pins 211 at two ends of the reed pipe 21, stress cannot be generated on the reed pipe 21, the initial performance of the reed pipe 21 is ensured to be good, and the interference fit between the pins 211 and the terminal clamping interfaces 232 is ensured due to the arrangement of the diameter.
