Description

A soldering wire type male head of a connector

Technical field:

The utility model relates to the technical field of electronic connector components, in particular to a wire-welding male head of a connector.

Background technique:

In the existing soldering type male headers of various connectors with plastic front body and rear plug structure, the connection between the plastic front body and the rear plug is realized by the buckle structure formed on both sides of the two, and the rear The plug has little contact with the metal housing on the plastic front body, and there is no connection structure. This makes the connection between the rear plug and the plastic front body weak and easy to fall off, and it is difficult to position in a wide range in the width direction, which is prone to problems such as loose connection and gaps after welding. In the subsequent process of forming the inner film In the process, the plastic material overflows from the gap, resulting in defective products.

Utility model content:

The purpose of the utility model is to overcome the above-mentioned shortcomings of the existing connection, and provide a soldering type male head for a tightly connected connector.

The technical solution adopted by the utility model to achieve its purpose is: a wire-welded male head of a connector, which includes a front plastic body with a metal terminal installed inside and a rear plug installed at the rear end of the front plastic body. A metal shell is also provided outside the plastic body, the metal shell extends to the outer surface of the rear plug, and a buckle protrusion is formed on the outer surface of the rear plug, and correspondingly, a Snap grooves.

After the utility model adopts the above-mentioned structure, the front plastic body and the rear plug of the male connector are based on the original connection structure, and the metal shell on the periphery of the front plastic body extends to the outer surface of the rear plug, and on the outer surface of the rear plug The buckle structure of buckle bumps and buckle grooves is formed between the metal shell, which makes the front plastic body and the back plug more accurately positioned and connected more closely, not only ensuring that the back plug does not fall off, but also ensuring There is no gap to ensure the normal progress of subsequent processing.

Description of drawings:

Fig. 1 is a schematic diagram of an exploded structure of a male connector of the utility model;

Fig. 2 is a schematic diagram of the combined structure of the male connector of the utility model.

Detailed ways:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

As shown in Figures 1 and 2, the wire-welding male head of the connector described in the present invention includes a front plastic body 1 with a metal terminal installed inside and a rear plug 2 installed at the rear end of the front plastic body 1. The front plastic body 1 is also provided with a metal shell 3. In this embodiment, the metal shell 3 is split, that is, a metal shell is installed on the front side of the front plastic body 1, and a metal shell is also installed on the back side. The metal shell 3 on the two sides Both extend out of the front plastic main body 1, which can be in contact with the outer surface of the rear plug 2, and a buckle bump 21 is formed on the outer surface of the rear plug 2, and the front and back are both provided. Correspondingly, on the outer surface of the rear plug 2 The two metal shells 3 above are respectively formed with buckle grooves 31. Therefore, when the rear plug 2 is connected to the front plastic body 1, the buckle bumps 21 of the rear plug 2 and the buckle on the metal shell 3 can be used. Groove 31 further strengthens its connection, making it more tightly connected. Of course, the shape and quantity of the buckle protrusions 21 of the rear plug 2 and the buckle grooves 31 on the metal shell 3 can be designed according to needs.

The utility model has simple structure and good connection effect.

Claims (1)
