Abstract

The utility model discloses a weight mesh type coupler, mainly aiming to solve the problems that an existing coupler employs a contact structure of a hollow copper column riveted with contacts; the contact is not full, and electric spark is easy to generate, thus potential safety hazards exist. The weight mesh type coupler comprises a housing, a left reed, a right reed and a grounding piece which are fixed on the housing, and solid core copper columns respectively riveted on the left reed and the right reed. The coupler of the utility model employs the solid core copper columns in such a way that contact areas between the coupler and a matching electric appliance can be enlarged, the contact is full, electric spark can be avoided and use security is increased; moreover, the weight mesh type coupler can reduce product material costs and raise production efficiency and is low-carbon, environment friendly, and hygienic.

Description

The engagement type coupler of weight

Technical field

The utility model relates to a kind of coupler, relates in particular to the engagement type coupler of a kind of weight.

Background technology

The engagement type coupler of weight (thermostat base) is installed on the heating plate of teapot electric appliances and the supporting use of electric equipment.At present; The contact structures of the engagement type coupler of weight adopt hollow copper post 2 to add the structure (as shown in Figure 1) of riveted silver contact 6 mostly, and the contact of this structure mainly is to lean on silver contact 6 contacts of riveted on hollow copper post 2, and the contact of general riveted joint very easily comes off or be loosening; So just make external connection electrical apparatus equipment insufficient when contacting with the engagement type coupler of weight; Be prone to rub the spark, infringement electrical equipment causes the human injury; In addition, also contaminated environment of the spark that produces of contact.

The utility model content

To the problems referred to above, the utility model provides the weight of a kind of full contact, safety and long service life engagement type coupler.

For achieving the above object, the engagement type coupler of the utility model weight comprises: housing, be fixed on the left reed on the said housing, right reed and grounding leg sheet and the copper post of riveted on said left reed and right reed respectively, said copper post is a solid copper pin.

Further, the surface of said solid copper pin also is provided with nickel coating.

The beneficial effect of the utility model is:

1, the utility model makes the contact area of external connection electrical apparatus equipment and this coupler strengthen through changing the hollow copper post in the contact point of the engagement type coupler of weight into solid copper pin, has improved useful life and touch-safe, environmental protection.

2, remove silver contact in the engagement type coupler of existing weight, greatly reduced the cost of producing material.

3, the utility model also is coated with one deck nickel dam outside said solid copper pin, has improved the corrosion resistance of copper post.

Embodiment

Below in conjunction with Figure of description the utility model is done further description.

The engagement type coupler of the said weight of the utility model comprises: housing, be fixed on the left reed on the said housing, right reed and grounding leg sheet and the copper post of riveted on said left reed and right reed respectively, said copper post is a solid copper pin.

As the further embodiment of the utility model, the surface of said solid copper pin also is provided with nickel coating, to improve the corrosion resistance of solid copper pin.

Embodiment 1

Shown in Fig. 2 to 4; The engagement type coupler of weight described in the present embodiment comprises: insulation shell 1, left reed 31, right reed 32, riveted the solid copper pin 21 on the left reed 31, riveted on right reed 32 solid copper pin 22 and be in left reed 31 and right reed 32 in the middle of grounding leg sheet 4.Said left reed 31, right reed 32 and grounding leg sheet 4 all adopt screw to be fixed on the said insulation shell 1.Wherein, it is more abundant that said solid copper pin 21 and 22 can make the external connection electrical apparatus that is in contact with it contact, and is difficult for producing spark, and can not cause any pollution to environment.In addition, middle ground connection film 4 can be guaranteed when electrical equipment safe in utilization during through electric current greatly such as electrical leakage or short circuit.

More excellent ground in practical application, solid copper pin is that diameter is that

highly is the cylinder of 7.6mm;

The screw of fixing said left reed 31, right reed 32 and grounding leg sheet 4 is the screw of M2*5.

The said weight engagement of the utility model makes the assembling technology procedure of coupler:

Solid copper pin on riveted on the reed of the left and right sides at first, respectively;

Then, be assembled to left and right sides reed and grounding leg sheet behind the good solid copper pin of riveted on the housing successively;

At last, through screw left and right sides reed and grounding leg sheet are fixed on the housing.

After adopting the described contact point of the utility model to be the nickel plating solid copper pin; Can make teapot electric appliances heating plate contact more abundant with teapot electric appliances placed on it; The contact structures that can never add the riveting silver contact because of the hollow copper post of selling in the market of employing, the contact of leaning on silver contact, and the silver contact of riveting over very easily comes off or loosening; The equipment that makes uses the generation spark, and contaminated environment also very easily causes personal injury; The solid copper pin of the utility model (nickel plating) contact-making surface is abundant, firm, and service life of equipment prolongs, also free from environmental pollution, low-carbon (LC), safety, and the product material use cost also reduces.

More than; Be merely the preferred embodiment of the utility model; But the protection range of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection range of the utility model.Therefore, the protection range of the utility model should be as the criterion with the protection range that claim was defined.

Claims

1. engagement type coupler of weight comprises: housing, be fixed on the left reed on the said housing, right reed and grounding leg sheet and the copper post of riveted on said left reed and right reed respectively, it is characterized in that said copper post is a solid copper pin.

2. according to the engagement type coupler of the said weight of claim 1, it is characterized in that the surface of said solid copper pin also is provided with nickel coating.
