Description

Small-size contact pin formula power transformer

Technical Field

The utility model relates to a power transformer technical field specifically is a small-size contact pin formula power transformer.

Background

The power transformer functions as power transmission, voltage conversion and insulation isolation, and is widely applied to power supply technology and power electronic technology as a main soft magnetic electromagnetic component. The small pin type transformer is made of EI-type steel sheets, is economical, simple and convenient, is wide in application and is suitable for PCB installation.

The existing pin type power transformer is generally formed by sheathing a shell on a power transformer body to form a whole, corresponding protective measures are lacked on the shell, and when equipment falls, a pin is very easy to contact with the ground due to the fact that the pin protrudes out of the periphery of the shell, so that the pin is very easy to damage.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a small-size contact pin formula power transformer through setting up the guard plate, can accomplish the safeguard function to the contact pin when the device is idle, has avoided because of falling the emergence that makes contact pin and ground direct contact damage's situation to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a small-size contact pin formula power transformer, includes shell and power transformer body, power transformer body joint is in the shell, shell outer wall bilateral symmetry sets up flutedly, both sides all are connected with the guard plate through the hinge rotation on the shell, the guard plate is located the recess, it is equipped with the magnetic path to correspond to inlay in bottom and the guard plate in the recess, the magnetic path lateral wall is spliced there is the aluminium foil, correspond in shell lateral wall, the recess and on the guard plate and set up the jack, it has the bolt to peg graft in the jack.

Preferably, the surfaces of the outer shell and the protection plate are provided with insulating paint layers.

Preferably, a spongy cushion is glued in the groove.

Preferably, the top of the two groups of grooves on the side wall of the shell are provided with openings.

Preferably, the anti-skid lines are arranged on the protection plate close to the opening.

Preferably, the protection plate is a plastic plate.

Compared with the prior art, the beneficial effects of the utility model are that:

when the device is idle, can 180 rotate the guard plate to parallel with the contact pin, the bolt of rethread both sides is fixed with it, during the use, only needs to take off two sets of bolts on the guard plate, in turning back the recess with the guard plate, the guard plate can be fixed under the actuation between two sets of magnetic paths, inserts the bolt in the jack on the shell again, can carry out the installation of power transformer body.
