Abstract

The utility model discloses a locating transformer frame protecting casing, which comprises a main embedding groove (1) and side embedding grooves (2), and the side embedding grooves (2) are arranged on two sides of the main embedding groove (1). The main embedding groove (1) is matched with a winding support (3) on a transformer frame in embedding mode, and the side embedding grooves (2) are matched with a base (4) on the transformer frame in embedding mode. Each side embedding groove (2) is provided with at least one locating post (5), the positions of the locating posts (5) correspond to locating holes (6) on a printed circuit board, and the locating posts (5) are clamped with the locating holes (6). By means of the locating transformer frame protecting casing, the weight of a whole transformer system not only stresses on a contact plane of a PIN and a printed circuit board (PCB) but also stresses more on the locating posts, the transformer is enabled to locate on the PCB accurately, and the transformer is enabled to be safer.

Description

Locate mode transformer framework containment vessel

Technical field

The utility model relates to the transformer technology field, specifically is a kind of locate mode transformer framework containment vessel.

Background technology

The transformer framework containment vessel is used to be nested in the transformer outside, with the internal structure of protection transformer.Said transformer framework containment vessel comprises main caulking groove and limit caulking groove, and said limit caulking groove is located at the both sides of main caulking groove.Drum stand on said main caulking groove and the transformer framework is chimeric, and the pedestal on said limit caulking groove and the transformer framework is chimeric.

The parts that common support transformer is gone up the location at printed circuit board (PCB) (being pcb board) are the metal stitch (being the PIN pin) on the transformer framework: on pcb board, contact part with the PIN pin earlier and smear tin cream; The pcb board that is placed with transformer is passed through the wave-soldering machine; The tin cream that spreads upon on the pcb board will melt; The metal stitch is welded on the pcb board, thereby transformer is fixed on the pcb board.

Transformer itself is because be to be processed by magnetic material and enamelled wire two big main materials; They are density height, material that weight is big, so the weight of transformer self is too big, cause the tin cream of thawing can't be with the transformer good location; Skew or vibration take place because of himself weight in the position of transformer on pcb board; Thereby make lead and draw pin and break off, perhaps draw pin, make the transformer short-circuit damage with pcb board unclamps.

The utility model content

The utility model technical problem to be solved provides a kind of locate mode transformer framework containment vessel of transformer good location on pcb board that make.

For solving the problems of the technologies described above, the locate mode transformer framework containment vessel of the utility model, it comprises main caulking groove and limit caulking groove, said limit caulking groove is located at the both sides of main caulking groove.

Drum stand on said main caulking groove and the transformer framework is chimeric, and the pedestal on said limit caulking groove and the transformer framework is chimeric.

Said limit caulking groove is provided with at least one reference column, and the position of said reference column is corresponding with the location hole on the printed circuit board (PCB), and said reference column and said location hole fasten.

The locate mode transformer framework containment vessel of the utility model; Through increasing reference column in containment vessel inside; Make the mass loading of whole transformer system not only drop on the contact-making surface of PIN pin and pcb board; More put forth effort on the reference column, transformer can accurately be positioned on the pcb board, make transformer safer.

As preferably, said limit caulking groove is provided with two reference columns.

Preferred as further, described two reference columns are located at the two ends of the limit caulking groove of the same side respectively.

Preferred as another, described two reference columns are located at respectively on the limit caulking groove of both sides.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.

The locate mode transformer framework containment vessel of the utility model, it comprises main caulking groove 1 and limit caulking groove 2, said limit caulking groove 2 is located at the both sides of main caulking groove 1.

Said main caulking groove 1 is chimeric with the drum stand 3 on the transformer framework, and said limit caulking groove 2 is chimeric with the pedestal 4 on the transformer framework.

Said limit caulking groove 2 is provided with at least one reference column 5, and the position of said reference column 5 is corresponding with the location hole 6 on the printed circuit board (PCB), and said reference column 5 fastens with said location hole 6.

The locate mode transformer framework containment vessel of the utility model; Through increasing reference column 5 in containment vessel inside; Make the mass loading of whole transformer system not only drop on the contact-making surface of PIN pin 7 and pcb board; More put forth effort on the reference column 5, transformer can accurately be positioned on the pcb board, make transformer safer.

As preferably, said limit caulking groove 2 is provided with two reference columns 5.

Preferred as further, described two reference columns 5 are located at the two ends of the limit caulking groove 2 of the same side respectively.

Preferred as another, described two reference columns 5 are located at respectively on the limit caulking groove 2 of both sides.
