Abstract

The invention discloses a power tube crimping device which comprises an inverted U-shaped supporting leg and a pressing plate, wherein the front side wall of the top of the inverted U-shaped supporting leg is connected with the pressing plate, an inserting groove is formed in the front side wall of the top of the inverted U-shaped supporting leg, a connecting bolt is inserted in the inserting groove, the lower end of the connecting bolt is in threaded connection with a supporting column, the supporting column is an internal thread hollow cylinder, an internal thread through hole is formed in the pressing plate, and the internal thread through hole is in threaded connection with a pressing bolt. The invention has simple structure, convenient installation and small occupied space, and does not need to change the structure of the original installation area. After the U-shaped supporting legs are fixed well, the power tube can be tightly attached to the mounting surface to prevent warping only by screwing down the compression bolts.

Description

Power tube crimping device

Technical Field

The invention relates to the technical field of mechanical equipment, in particular to a power tube crimping device.

Background

The power tube is a power device with wide application, the bottom is made of heat sink material, and stable heat dissipation measures are needed to ensure reliability after long-time work. The bottom of the power tube is designed in a plane, and theoretically, the heat sink at the bottom of the power tube is completely contacted with the radiating fins after installation, so that the radiating effect and the service life of the device can be guaranteed.

At present, the problem of warping of the power tube is solved by adopting pressing strips or U-shaped clamping pieces, but the solution occupies a large space, needs to change the structure of the original installation area, and is not easy to realize under the condition of dense layout of printed board components.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides a power tube crimping device.

In order to achieve the purpose, the technical scheme of the invention is as follows: a power tube crimping device is characterized in that: including type of falling U landing leg and clamp plate, lateral wall connection clamp plate before the type of falling U landing leg top, lateral wall is equipped with the inserting groove before the type of falling U landing leg top, inserting connection bolt in the inserting groove, connecting bolt lower extreme threaded connection support column, the support column is internal thread cavity cylinder, the clamp plate is equipped with the internal thread through-hole, internal thread through-hole threaded connection clamp bolt.

Further, the method comprises the following steps of; the glass cloth plate pad is arranged below the compression bolt.

The invention has the beneficial effects that: the invention has simple structure, convenient installation and small occupied space, and does not need to change the structure of the original installation area of the power tube. After the U-shaped supporting legs are fixed well, the power tube can be tightly attached to the mounting surface to prevent warping only by screwing down the compression bolts.

Detailed Description

Example (b):

as shown in fig. 1 to 3, a power tube crimping device comprises an inverted U-shaped support leg 1, a pressing plate 2 and a glass cloth plate pad 3, wherein the pressing plate 2 is connected to the front side wall of the top of the inverted U-shaped support leg 1, and the inverted U-shaped support leg 1 and the pressing plate 2 are integrally formed. The glass cloth plate pad is characterized in that an inserting groove 4 is formed in the front side wall of the top of the inverted U-shaped supporting leg 1, a connecting bolt 5 is inserted in the inserting groove 4, the lower end of the connecting bolt 5 is in threaded connection with a supporting column 6, the supporting column 6 is an internal thread hollow cylinder, the pressing plate 2 is provided with an internal thread through hole 7, the internal thread through hole 7 is in threaded connection with a pressing bolt 8, and the glass cloth plate pad 3 is arranged below the pressing bolt 8.

When the support is used, the inverted U-shaped support leg 1 is supported on printed boards on two sides of a lug plate of a power tube 9, the lower end of the support column 6 is in threaded connection with a fixing bolt 10 of the lug plate and abuts against a fixing nut 11 of the fixing bolt 10, and the inverted U-shaped support leg 1 is fixed on the printed board 12 by screwing the connecting bolt 5. And (3) placing the glass cloth plate pad 3 above the power tube 9, and screwing down the compression bolt 8 to enable the lower end of the compression bolt 8 to be abutted against the glass cloth plate pad 3.

The above-described embodiments are merely preferred embodiments of the present invention, which is not intended to be limiting in any way, and other variations and modifications are possible without departing from the scope of the invention as set forth in the appended claims.

In the description of the present invention, it is to be understood that the terms indicating an orientation or positional relationship are based on the orientation or positional relationship shown in the drawings only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
