Four clamping bulges are arranged at the edge part of the reed structure.

And (5) stamping and forming the clamping bulge.

The upper terminal shell and the lower terminal shell are fixedly provided with positioning convex columns, the reed structure is provided with a through hole, and the positioning convex columns penetrate through the through hole.

Terminal sheaths are arranged at the edge parts of the upper terminal shell and the lower terminal shell.

Compared with the prior art, the utility model has the technical effects that the reed structure can adapt to the switching of two opposite insertion modes of 180 degrees and 90 degrees without adjustment after rotating for 90 degrees as the original shape.

Detailed Description

The utility model will be described in detail below with reference to the drawings and detailed description thereof.

Referring to fig. 1 to 4, a chip type high current terminal includes an upper terminal housing 20 and a lower terminal housing 10, rear end portions of the upper terminal housing 20 and the lower terminal housing 10 are fixed together by a connection structure 21, the upper terminal housing 20 and/or the lower terminal housing 10 are Z-shaped, a receiving space is provided between front end portions of the upper terminal housing 20 and the lower terminal housing 10, and reed structures 30 are fixed to inner surfaces of front end portions of the upper terminal housing 20 and the lower terminal housing 10.

As shown in fig. 4, the reed structure 30 is rotated counterclockwise or clockwise by 90 ° and has the same shape as before, and includes a plurality of radial reeds 31, the outer ends 312 of the reeds 31 are fixed to the reed structure 30, the reeds 31 gradually rise along with the inward end extension, and the reeds 31 continue to extend to form a slope 313 after extending to the highest point 311.

As shown in fig. 4, four clamping protrusions 33 are provided at the edge of the reed structure 30, and the upper and lower clamping protrusions 33 can clamp the tab terminal, so that the tab terminal can be stabilized between the upper and lower reed structures 30.

The clamping protrusion 33 is formed by stamping, so that the clamping protrusion 33 is more elastic in the axial direction thereof, thereby facilitating clamping of the tab terminal.

As shown in fig. 4-5, in order to facilitate accurate positioning of the reed structure 30, the upper terminal housing 20 and the lower terminal housing 10 are fixed with positioning bosses 15, through holes 32 are provided on the reed structure 30, and the positioning bosses 15 penetrate through the through holes 32.

As shown in fig. 2, the edge portions of the upper terminal housing 20 and the lower terminal housing 10 are provided with terminal jackets 40.

As shown in fig. 1, for convenience of connection, the connection structure 21 is a connection hole and a bolt.

The working principle is as follows:

when in use, no matter the inserting mode of the inserting sheet terminals is adopted according to 180 degrees and 90 degrees, the inserting sheet terminals can enter along the outer end parts 312 of the first pair of reeds 31 during inserting, and the first pair of reeds 31 can be extruded towards the respective directions along the upward slope section and beyond the highest point 311; when the tab terminal enters the section of the two pairs of reeds 31, it passes over its highest point 311 along the sloping section 313 and continues to be inserted forward, completing the compression of the second pair of reeds 31 in the respective directions, such that the tab terminal is sandwiched between the two reed structures 30, completing the electrical connection.

In addition, if the terminals are matched at 90 degrees and 180 degrees, only the corresponding directions of the terminal sheath 40 are changed, the inserted sheet terminals are inserted in the direction without the terminal sheath 40, and the sheet type high-current terminal and the reed are not required to move, so that the terminal is convenient.

In addition, by clamping the tab terminal by the clamping projection 33, the stability of the tab terminal is more easily maintained.

See the prior art for further content.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
