Abstract

The utility model relates to an improved outer shell of a connector. A connector is coated in a metallic shell body, and a layer of nickel is plated on the surface of the shell body. Open end edges at both sides of the shell body are embedded with at least one opposite connecting pin, and the surface of the connecting pin is plated with a layer of tin. When a user needs to fix the shell body on a machine plate, marks can not be scratched on the surface of the shell body due to the hard characteristic of the nickel on the surface of the shell body when a welding tool scratches the shell body, and the shell body can not be softened to deform due to high temperature generated during welding. Simultaneously, the connecting pin can be easily fixed in the machine plate in a welding method since the surface of the connecting pin is plated with the tin, and further the shell body is fixed on the machine plate.

Description

The connector shell of improvement

Technical field

The utility model relates to a kind of connector shell of improvement, it is a kind of surface at the coupled pin of metal shell, electroplate one deck nickel and tin respectively, and make surface of shell when welding, not only can pass through the hard characteristic of nickel, unlikely being injured, and can pass through the lip-deep tin of pin, pin can be weldingly fixed in the machine plate easily.

Background technology

General traditional connector, the surface that is provided with a framework is coated with a metal shell, and this framework is provided with more than one dividing plate, to make this conductor frame can pass through the separation of these dividing plates, and the most individual accommodation spaces of formation, be installed with a joint in these accommodation spaces respectively, be plugged with the inserting terminal that extends to the framework rear end in these joints respectively, this kind device is on being fixed in the machine plate time, because case surface is zinc-plated, and the material of tin is to belong to softlyer at metal material, and fusing point is lower, therefore, when the pin sleeve on this shell is on the machine plate, when bump being welded in pin and machine plate contact position, between action, can touch case surface unavoidably because of the welding gun desire, and this case surface of scratch, and when welding gun is welding pin when producing high temperature, because of this case surface is zinc-plated, and make this shell softening, and then cause the problem of distortion.

Summary of the invention

For improving above-mentioned various shortcomings, the inventor is to be engaged in such manufacturing industry experience for many years, and through the permanent research and experiment of making great efforts, development and Design goes out the technical solution of the utility model finally.

The purpose of this utility model provides a kind of connector shell of improvement, by electroplating one deck nickel and tin respectively on the surface of the coupled pin of metal shell, when making user's desire be fixed on this housing on the machine plate, because of this surface of shell has nickel, it is unlikely when soldered instrument streaks, and stay scratch on its surface, and this housing more can not soften because of the high temperature that soldering appliance produced, simultaneously, be zinc-plated because of its pin surface again, and these pins can be fixed in the machine plate by the mode of welding easily, and then housing is fixed on the machine plate.

The purpose of this utility model is achieved in that a kind of connector shell of improvement, it is characterized in that: it includes the surface of shell that is made of metal and is coated with nickel, and these housing both sides respectively are provided with at least one relative embedding hole in the adjacent bottom open end; More than one pin is that interlocking is on these housing both sides, these pin surfaces are coated with tin, and these pins are provided with a pedestal, this pedestal one termination is provided with one-body molded with it and outward extending pin, the other end then is provided with inlay, and this pedestal is provided with clamp on an end that joins with pin, this pin by the inlay buckle in the embedding hole, reach the clamp folder and lean against the housing both sides and be on the ora terminalis of open shape bottom connection, combine with this housing.The chrome-faced of this housing.

Describe in detail below in conjunction with the preferred embodiment conjunction with figs..

Fig. 2 is a schematic perspective view of the present utility model.

Fig. 3 is a user mode schematic diagram of the present utility model.

Embodiment

Consult shown in Figure 1, the utility model is a kind of connector shell of improvement, this structure is provided with a metal shell 10 that is open shape, be coated with the higher metal material (as chromium) of nickel or other hardness on these housing 10 surfaces, and these housing 10 front ends are provided with an opening 11, be mounted in the housing 10 with (as shown in Figure 3) for a connector 30, this opening 11 also is connected with the open end of bottom.

These housing 10 both sides respectively are provided with a supreme relative embedding hole 12 at place, adjacent bottom open end, in present embodiment embedding hole 12 is 2, be embedded with a surface in these embedding holes 12 respectively and be coated with the pin 20 of tin, these pins 20 are provided with a pedestal 21, these pedestal 21 1 terminations are provided with one-body molded with it and outward extending pin 22, the other end then is provided with the inlay 211 that bends inwards, but these inlay 211 proper buckles are in embedding hole 12, and this pedestal 21 is provided with clamp 212 on an end that joins with pin 22, to make this pin 20 can pass through inlay 211 buckles in embedding hole 12, reach clamp 212 folders and lean against housing 10 both sides and be on the ora terminalis of open shape bottom connection, and combine (as shown in Figure 2) with housing 10.

Consult shown in Figure 3, a connector 30 is inserted in the housing 10 by opening 11, this connector 30 is provided with more than one joint 31, these joints 31 can change with the need, and be provided with the terminal (not shown) that most roots are connected with these joints 31 and extend to housing 10 bottoms in this connector 30, again with this housing 10 together with wherein connector 30 sleeves after (not shown) on the machine plate and pin 22 sleeves that make the pin 20 on the housing 10 are in the default hole of machine plate, pin 20 is welded on the position with scolding tin by soldering appliance, and make housing 10 can be fixed on the position, unlikely rocking, and as user during in the work of welding, because of these housing 10 surfaces are coated with nickel, it is unlikely when soldered instrument streaks, the surface stays scratch, and this housing 10 more can not soften because of the high temperature that soldering appliance produced, produce distortion, simultaneously, be zinc-plated because of its pin 20 surfaces again, and make these pins 20 can be welded on the machine plate easily, and then housing 10 is fixed on the machine plate, so, not only can protect the attractive in appearance of housing 10 integral body, and install also very easy.

In sum, the connector shell of improvement of the present utility model has the enjoyment in simple structure, practicality and increase space, and improves the wish that the consumer uses; So the utility model really can be improved the disappearance of conventional construction, and tool is promoted the practicality of effect.The utlity model has novelty, creativeness and practicality.
