Abstract

The utility model discloses a male end limiting plug-in terminal which comprises a female end, a connecting part and a fixing part, wherein a convex block is inwards prepared on the side edge of the female end. The bumps are two on each side. The utility model has the advantages that: the utility model changes the original connection mode, and on the basis of integrating the original connection structure which needs to be finished by welding into a structure that the male end is connected with the female end, the primary lug is stamped in the box on the side edge of the female end, so as to limit the gap after the male end is inserted into the female end, so that the male end does not send shake any more, ensure the stable electrical contact, realize the automation of product assembly, improve the production efficiency and prolong the service life of the product.

Description

Male end limiting plug-in terminal

Technical Field

The utility model relates to a terminal for connecting a lead inside a household appliance, in particular to a male end limiting plug-in terminal.

Background

In the prior art, a connecting terminal applied to an electric kettle is shown in fig. 1, the earliest female end 2 is a soldering lug, the earliest male end 1 is also a soldering lug, and the two are welded, however, the product mainly exits the European and American markets, the welding mode is limited by environmental protection requirements, the normal use of the product can be influenced, moreover, the product is currently welded in a single piece, the actual automation cannot be realized, the production efficiency is low, and the long-term welding work influences the health of a human body, so that the male end 1 and the female end 2 are changed into the plugging mode shown in fig. 1.

In the prior art shown in fig. 1, after the male end 1 is inserted into the female end 2, the end stopper 23 on the female end 2 abuts against the male end 1 and cannot be inserted, and the bottom plate protrusion 24 locks the male end 1.

It seems that the prior art has been improved well to solve the problem of the inability of welding between the male end 1 and the female end 2, but tests have found that there is a problem:

that is, after the positioning hole 11 of the male end 1 is sleeved on the bottom plate protrusion 24, because a certain gap exists between two sides of the male end 1 and the inner wall of the female end 2, the male end 1 can rotate around the bottom plate protrusion 24, which is undesirable, and we want to insert the male end 1 and the female end firmly.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that the male end 1 can rotate around the bottom plate bulge 24 in the prior art, and designs the male end limiting plug-in terminal.

The utility model is realized by the following steps: design and implement a public spacing plug terminal of end, include:

female end, connecting portion and fixed part, on the side of female end, inwards prepare the lug.

The bumps are two on each side.

The protruding size of the lug at the inner wall of side is 0.8mm 0.4 mm.

The height of the protruding block protruding from the inner wall of the side edge is 0.1 mm.

The utility model has the advantages that: the utility model changes the original connection mode, and on the basis of integrating the original connection structure which needs to be finished by welding into a structure that the male end is connected with the female end, the primary lug is stamped in the box on the side edge of the female end, so as to limit the gap after the male end is inserted into the female end, so that the male end does not send shake any more, ensure the stable electrical contact, realize the automation of product assembly, improve the production efficiency and prolong the service life of the product.

Detailed Description

The present invention will be described in further detail with reference to preferred embodiments.

Referring to fig. 2 to 5, the plug terminal with a limited male end is designed and manufactured, including:

the female terminal 2, the connecting portion 3 and the fixing portion 4, on the side 21 of the female terminal 2, a bump 22 is prepared inward.

The bumps 22 are prepared two on each side 21.

The projection 22 protrudes at the inner wall of the side 21 by a dimension of 0.8mm by 0.4 mm.

The height of the protrusion 22 protruding from the inner wall of the side 21 is 0.1 mm.

As can be seen from FIG. 1, the width of the male end is 4.75mm, as can be seen from FIG. 4, the thickness of the material is 0.4mm, and as can be seen from FIG. 2, the width of the female end is 5.8 mm.

Thus the internal width of the female end is 5.0 mm.

The male end with the width of 4.75mm can shake in the female end, and after the lug disclosed by the utility model is arranged, the male end can be smoothly inserted into the female end, and no shaking space is formed.

It should be noted that the dimensions shown in fig. 2, 4 and 5 are only the dimensions of the preferred embodiment, and when the overall dimensions of the male-end-limiting plug terminal become larger, the dimensions will be correspondingly larger when the current passing through the male-end-limiting plug terminal becomes larger. The structure of the utility model is the main point of protection.

The above description is only a preferred embodiment of the present invention, and the present invention should not be limited by the above description, which should be interpreted as limiting the scope of the present invention, since the person skilled in the art can change the utility model in the details of the embodiment and the range of applications according to the spirit of the present invention.
