Abstract

The utility model discloses a clamp capable of ensuring the planeness of a hollow coil inductor enamelled wire shell. The clamp comprises a substrate (1), wherein a positioning plate (2) is arranged on the substrate (1); more than two hollow coil placing grooves (3) are formed in the positioning plate (2); the depth of the hollow coil placing grooves (3) and the depth of the enamelled wire shell are equal to the height of a hollow coil. After glue is coated in the enamelled wire shell, when the enamelled wire shell is connected with the hollow coil, the bottom edge of the enamelled wire shell is in contact with the upper end face of the positioning plate, and the planeness of the enamelled wire shell after connection is ensured.

Description

Can guarantee the fixture of air core coil inductor enamelled wire shell flatness

Technical field

The utility model relates to a kind of fixture that can guarantee air core coil inductor enamelled wire shell flatness, belongs to inductor production auxiliary equipment technical field.

Background technology

Range of inductor is various; use extensively; the application is for the air core coil inductor with protective paint envelope curve shell; such inductor is to connect a containment vessel at the top of air core coil glue; its structure as shown in Figure 3; the existing production to such inductor mostly is manual gluing and connects; because air core coil top contacts with the line that is connected to of containment vessel; under existing connected mode, often can cause coil two pads cannot be parallel with shell; when welding on circuit board; two pins contacts with circuit board, causes that product plane degree does not reach the problem of requirement.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of fixture that can guarantee air core coil inductor enamelled wire shell flatness, can overcome the deficiencies in the prior art.

The technical solution of the utility model is: the fixture that can guarantee air core coil inductor enamelled wire shell flatness, it comprises substrate, on substrate, be placed with location-plate, on location-plate, offer plural air core coil standing groove, the degree of depth of air core coil standing groove is the height that the degree of depth that the degree of depth of air core coil standing groove adds enamelled wire shell equals air core coil.

Compared with the prior art, the utility model relates to a kind of inductor protecting sheathing sectional fixture, its clamp structure is two-layer plate body, lower floor's plate body is origin reference location plate, top plate is offering the hole matching with inductor air core coil, after like this air core coil contraposition being placed, just can make drum and substrate contacts, guarantee the level of air core coil, it by the degree of depth of air core coil standing groove, is the height that the degree of depth that the degree of depth of air core coil standing groove adds enamelled wire shell equals air core coil simultaneously, like this in enamelled wire shell after gluing, while being connected with air core coil, the base of enamelled wire shell will contact with location-plate upper surface, guarantee the flatness after enamelled wire shell connects.

Accompanying drawing explanation

Fig. 1 is the structural representation of location-plate;

Fig. 2 is the structural representation of substrate;

Fig. 3 is finished product structure schematic diagram of the present utility model.

Embodiment

As shown in Figure 3, it is the product with the supplement production of this fixture, and its product structure is that epoxy glue links together enamelled wire shell and enameled wire loop, and enameled wire loop two exits form Surface Mount pad structure.

For guarantee the combination of enamelled wire shell and enameled wire loop be levelness, employing fixture positions, its fixture consists of substrate (1) and location-plate 2, the material of substrate (1) and location-plate 2 is bakelite plate, also can adopt metallic plate, on substrate (1), be placed with location-plate (2), on location-plate (2), offer plural air core coil standing groove (3), the degree of depth of air core coil standing groove (3) is the height that the degree of depth that the degree of depth of air core coil standing groove (3) adds enamelled wire shell equals air core coil.

During use, air core coil is placed in air core coil standing groove 3 (" Z " type location hole); In enamelled wire shell, smear epoxy glue, then the two is combined, the upper surface laminating of enamelled wire shell and location-plate 2 can be guaranteed evenness.

Claims

1. the fixture that can guarantee air core coil inductor enamelled wire shell flatness, it is characterized in that: it comprises substrate (1), it is characterized in that: on substrate (1), be placed with location-plate (2), on location-plate (2), offer plural air core coil standing groove (3), the degree of depth of air core coil standing groove (3) is the height that the degree of depth that the degree of depth of air core coil standing groove (3) adds enamelled wire shell equals air core coil.
