Abstract

The utility model relates to the technical field of microelectronic transformers, in particular to a transformer with a filtering function, which is used in an Ethernet port connector. The transformer comprises a basal body, inductance coils and terminals; wherein, both the inductance coils and the terminals are arranged on the basal body; the terminals are provided with containing spaces; and the leads of the inductance coils are placed in the containing spaces. Since the utility model employs the terminals of the containing spaces provided with containing leads, the leads are directly placed or inserted in the terminals and then welded with the terminals after being cut, and thereby, the operation steps of the conventional technique, which include winding, compressing, positioning, cutting and welding, are simplified, only including straight insertion, cutting and welding, so the structure is simple, the operation is convenient and the efficiency is high. Moreover, since the original lead-winding operation is changed into placement or straight insertion and the terminals cannot be easily short-circuited during welding, the space between each two terminals can be greatly reduced, and as a result, more inductance coils and terminals can be placed in the same space.

Description

A kind of transformer that is used for connector

Technical field:

The utility model relates to the microelectronic transformer technical field, particularly a kind ofly is used for the transformer that the Ethernet interface connector has filter function.

Background technology:

The RJ45 connector has all been integrated the transformer of filter function mostly at present, development along with network transmission technology, data transmission bauds is more and more faster, for reaching good filtering effect, the inductance coil quantity that is incorporated into the transformer of RJ45 connector inside also increases along with the quickening of transmission speed, also require to increase the binding post of inductance leads, for reaching the versatility of RJ45 connector construction size, this just requires the peripheral space size constancy of RJ45 connector.According to existing transformer combination technology, under the situation of space invariance, along with the increase of inductance binding post quantity, the production operation difficulty of this transformer is increasing, and the defective products rate in the production process is more and more higher.

See Fig. 1, shown in 2, the transformer of the existing RJ45 of being incorporated into connector inside comprises matrix 10, inductance coil 11 and terminal 12, inductance coil 11 is arranged on the matrix 10, terminal 12 is for being arranged on the solid cylinder at matrix 10 tops, the lead 14 of inductance coil 11 is wrapped in respectively on the terminal 12, through tightening, the location, after the operations such as trimming, at last lead 14 and terminal 12 are welded together, restriction because of the space, the spacing that terminal is 12 is less, is difficult to operation when twining lead 14, and efficient is lower, and when lead 14 and terminal 12 are welded together, 12 problem of short-circuit of terminal appear easily.

The utility model content:

The purpose of this utility model is to provide a kind of operation to be used for the transformer of connector easily at the deficiencies in the prior art.

For achieving the above object, the utility model adopts following technical scheme:

A kind of transformer that is used for connector, it includes matrix, inductance coil and terminal, and inductance coil and terminal all are arranged on the matrix, and described terminal is provided with accommodation space, and the lead of inductance coil is placed in the described accommodation space.

The top of described accommodation space penetrating terminal and bottom.

The cross section of terminal is annular, " returning " shape, " U " shape, " D " shape or " Z " shape.

Described matrix is circuit board or plastic cement piece.

Offer groove on the described matrix, inductance coil is arranged in the groove.

Be provided with dividing plate in the described groove.

Described matrix top offers the through hole that connects the bottom, and terminal is plugged in the through hole.

Described terminal extends the bottom of matrix.

The utility model beneficial effect is: the utility model includes matrix, inductance coil and terminal, inductance coil and terminal all are arranged on the matrix, described terminal is provided with accommodation space, the lead of inductance coil is placed in the described accommodation space, the utility model has adopted the terminal of the accommodation space with ccontaining lead, lead is directly placed or is located in terminal inside, trimming and lead and terminal welded together then, thus the winding of conventional art, tighten, the location, the job step of trimming and welding is reduced to straight line and wears, trimming and welding, simple in structure, operation is convenient, the efficient height; Because of changing into, the operation action that original lead is twined places or straight line wears again, and when welding, be difficult for short circuit between terminal, so the distance between terminal can significantly reduce, on same space, can place more inductance coil and terminal, therefore to have solved the task difficulty of running in the prior art big for the utility model technology, efficient is low, the problem of insufficient space.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described, see Fig. 3-5, a kind of transformer that is used for connector, it includes matrix 20, inductance coil 21 and terminal 22, matrix 20 is circuit board or plastic cement piece, matrix 20 tops offer groove 23, inductance coil 21 is provided with lead 24, inductance coil 21 is arranged in the groove 23 of matrix 20, matrix 20 tops are provided with two row's terminals 22 in the both sides of groove 23, matrix 20 tops offer the through hole 26 that connects the bottom, and terminal 22 is plugged in the through hole 26.Terminal 22 is provided with accommodation space 28, and the lead 24 of inductance coil 21 is placed in the accommodation space 28.The cross section of terminal 22 is annular, " returning " shape, " U " shape, " D " shape or " Z " shape, its clearance space forms accommodation space 28, accommodation space 28 on the terminal 22 of present embodiment is for connecting the circle hole shape passage of terminal 22 tops and bottom, it is communicated with the top and the bottom of matrix 20, terminal 22 extends the bottom of matrix 20, lead 24 passes terminal 22 respectively after inductance coil 21 comes out, and stretch out from the bottom of terminal 22, then lead 24 is welded on the circuit board 27 with terminal 22.

Be provided with dividing plate 25 in the groove 23, when the inductance coil 21 of group more than being provided with in the groove 23, dividing plate 25 can be organized each inductance coil 21 and separate.

The utility model has adopted the terminal 22 of the accommodation space 28 with ccontaining lead 24, lead 24 is directly placed or is located in terminal 22 inside, trimming and lead 24 and terminal 22 welded together then, thus the job step of the winding of conventional art, deflation, location, trimming and welding be reduced to that straight line wears, trimming and welding, simple in structure, operation is convenient, the efficient height; Because of changing into, the operation action that original lead 24 is twined places or straight line wears again, and 22 of terminals are difficult for short circuit when welding, so the distance that terminal is 22 can significantly reduce, on same space, can place more inductance coil 21 and terminal 22, therefore to have solved the task difficulty of running in the prior art big for the utility model technology, efficient is low, the problem of insufficient space.
