Description
Technical Field
The utility model relates to an electronic components field, concretely relates to fast assembly formula transformer.
Background
The transformer consists of an iron core (or a magnetic core) and a coil, wherein the coil is provided with two or more than two windings, the winding connected with a power supply is called a primary coil, and the other windings are called secondary coils. It can transform alternating voltage, current and impedance. The simplest iron core transformer consists of an iron core made of soft magnetic material and two coils with different turns sleeved on the iron core. The main functions are as follows: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), and the like. The coil and the like are fixed inside the existing transformer, and the assembly is troublesome, so that the transformer which is assembled quickly is very important.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a fast assembly type transformer, which comprises a transformer element and a transformer shell fixed outside the transformer element, wherein the transformer element comprises an iron core, a primary coil and a secondary coil which are respectively wound on two sides of the iron core, a rectangular hollow part is arranged at the center of the iron core, and arc hollow parts which are symmetrical due to the connection of the rectangular hollow parts are arranged on two sides of the rectangular hollow part; transformer case includes base and top shell, and the integrated into one piece that makes progress has the arc arch that matches with the circular arc fretwork on the base, and the downward integrated into one piece in top shell bottom has the buckle, set up on the inner wall of base both sides with buckle complex buckle groove. The arc-shaped bulge bottom is integrally formed with a limiting ring.
Grooves for the lead wires of the primary coil and the secondary coil to pass through are formed in the two sides of the base. A matching bulge is integrally formed on the top shell and corresponds to the groove, and a through hole for a lead to pass through is formed in the matching bulge. The four corners of the base are integrally formed with a triangular prism table for supporting.
Compared with the prior art, the utility model has the advantages of: the utility model discloses a top cap and base carry out the lock through the buckle, and primary and secondary's wire can spill in the perforation, and top cap and base are not touched to winding coil on can guaranteeing the iron core to spacing ring and arc arch, and is fixed with the base in the installation, after putting into the iron core afterwards, the buckle connect the top cap can, the installation is convenient fast.
