Abstract

The utility model discloses a kind of network transformer housing, including housing, it is characterized in that, the groove for placing magnet ring is provided with described housing, some wiring pins are provided with housing, it is provided with described wiring pin for the binding post that is connected with the enamel-covered wire on magnet ring, the end of described binding post and has opened up welding groove toward the opening direction of groove on the top of binding post.Enamel-covered wire on magnet ring is directly placed into network transformer housing described in the utility model the welding groove on binding post top by the way of butt-joint, the process of placement is to be capable of achieving welding, working power is effectively reduced, so as to reduce process operation fussy degree, shorten machining period, improve production efficiency.

Description

A kind of network transformer housing

Technical field

The utility model is related to network transformer technical field, more particularly to a kind of network transformer housing.

Background technology

Network transformer is indispensable part in network interface card circuit, it mainly comprising centre tap electric capacity, transformer, from Coupling transformer, common mode inductance.The transformer typically all near the input of network interface card, is coupled and isolated for signal level Outside interference and impedance matching is realized, can thus increase transmission range, while being isolated from the outside chip, enhancing is anti- Interference performance.

The binding post of legacy network transformer uses wound form with the enamel-covered wire connected mode on magnet ring, binding post The less groove segment of bore is provided with main body, enamel-covered wire is wrapped on groove segment and then is welded and fixed again.This kind of structure connects Terminal welding assembly technique is relatively complicated, it is necessary to very fine manual operations, and labour intensity is big, it is difficult to realize automated production, Packaging efficiency is low.

Utility model content

Technical problem to be solved in the utility model and the technical assignment for proposing are that prior art is improved, there is provided A kind of network transformer housing, network transformer case weld assembling traditional in the current technology of solution is cumbersome, and labour intensity is big, The low problem of packaging efficiency.

To solve above technical problem, the technical solution of the utility model is：

A kind of network transformer housing, including housing, it is characterised in that be provided with described housing and place the recessed of magnet ring Groove, is provided with some wiring pins on housing, being provided with described wiring pin is used for and connecing that the enamel-covered wire on magnet ring is connected Terminal, the end of described binding post and has opened up welding groove toward the opening direction of groove on the top of binding post.This Network transformer housing described in utility model sets welding groove on the top of binding post, and the enamel-covered wire on magnet ring is used into butt-joint Mode be directly placed into welding groove and be capable of achieving to be welded to connect, without enamel-covered wire is wrapped on binding post again, reduces and grasp Make operation, so as to improve processing efficiency, reduce labour intensity, improve the economic benefit of production.

Further, described welding groove is wide at the top and narrow at the bottom so that welding groove can be fully contacted with enamel-covered wire, it is to avoid contact is not It is good, ensure the electric property of good stabilization.

Further, described welding groove is triangular in shape, makes welding groove abundant with enamel-cover linear contact lay.

Further, diameter of the depth of described welding groove more than the enamel-covered wire on magnet ring, it is ensured that be welded to connect completion Enamel-covered wire will not be higher by the top of binding post afterwards, ensure the planarization on binding post top, it is to avoid unexpected touching causes connection to separate, Improve connective stability.

Further, described wiring pin generally U-shaped bending part, interspersed to be fixed on the side wall of groove, U-shaped bending part Side be binding post, opposite side be with extraneous welding foot be connected, the enamel-covered wire on magnet ring is by wiring pin and extraneous realization Electrical connection.

Further, described wiring pin uniform intervals arrangement, and it is symmetricly set on two offsides of housing.

Compared with prior art, the utility model advantage is：

Network transformer housing described in the utility model is directly placed the enamel-covered wire on magnet ring by the way of butt-joint Enter the welding groove on binding post top, the process of placement is to be capable of achieving welding, working power is effectively reduced, so as to reduce process operation Fussy degree, shortens machining period, and improve production efficiency, welding stability is good, ensures good electric property.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the structural representation of binding post.

Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

A kind of network transformer housing disclosed in the utility model embodiment, reduces operational sequence, reduces process operation difficult Degree, shortens machining period, improve production efficiency.

As depicted in figs. 1 and 2, a kind of network transformer housing, including housing 1, housing 1 is overall in the recessed of rectangle Groove, magnet ring 2 is placed in groove, and some evenly distributed wiring pins 3 are provided with 1 liang of wall of offside of housing.

The generally U-shaped bending part of wiring pin 3, interspersed to be fixed on the side wall of groove, the side of U-shaped bending part is binding post 31, opposite side is to be used to be connected with the enamel-covered wire on magnet ring 2 with the extraneous welding foot 33 being connected, binding post 31, binding post 31 End and has opened up welding groove 32 toward the opening direction of groove on the top of binding post 31, and the depth of welding groove 32 is big In the diameter of the enamel-covered wire on magnet ring 2, welding groove 32 is wide at the top and narrow at the bottom, and in the present embodiment, welding groove 32 is triangular in shape so that magnetic What the enamel-covered wire of ring 2 can be stablized is fastened on welding groove 32, ensures that contact is abundant, improves the stability of electrical connection, and enamel-covered wire is straight Connect be placed into binding post top welding groove can realize welding, reduce manufacturing procedure, reduce labour intensity, improve production efficiency.

The above is only preferred embodiment of the present utility model, it is noted that above-mentioned preferred embodiment should not be regarded It is that, to limitation of the present utility model, protection domain of the present utility model should be defined by claim limited range.For For those skilled in the art, do not departing from spirit and scope of the present utility model, can also make some Improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
