Description

electrical connector

Technical field:

The utility model relates to the technical field of computer accessories, in particular to an electric connector.

Background technique:

With the advancement of science and technology, electronic products, as the fastest growing industry, can be said to be changing with each passing day, and the product replacement cycle is getting shorter and shorter. However, as an accessory product of electronic products - electrical connectors, due to the existing The connection between the electrical connector and the circuit board is to directly weld the metal plate on the electrical connector to the circuit board. If the metal plate on the electrical connector and the solder are not welded firmly, it is easy to make the electrical connector loose, resulting in electrical failure. The connection is poor, or even broken. In addition, most of the existing electrical connector terminals adopt U-shaped design. Because of its small flexibility, if the electric plug is repeatedly inserted and pulled, it will cause poor contact and directly affect normal operation of electronic products.

Invention content:

The purpose of the utility model is to provide an electrical connector which can be reliably welded with a circuit board and has good contact.

The utility model is realized in the following way: the electrical connector includes a housing and a connecting terminal, the connecting terminal is inserted into the installation groove of the housing, and the feature is that the upper part of the connecting terminal is an S-shaped external contact part, and the lower part It is connected with the horizontal welding feet, and the outer surface of both sides of the shell is provided with sockets, one right-angled plate of a right-angled mounting plate is inserted into the socket, and the middle part of the other right-angled plate of the mounting plate is provided with a through hole. The right-angle plate and the welding feet are in the same plane, and the supporting wall for placing the welding feet of the terminal on the housing is a horizontal supporting wall.

Protrusions for positioning the housing are provided on both sides of the right-angled side of the mounting plate inserted into the insertion port, and correspondingly, grooves for accommodating the protrusions are provided in the insertion port of the housing.

The above-mentioned through holes on the mounting board have a certain taper, and the hole diameter on the side contacting the circuit board is smaller.

Compared with the prior art, the outstanding advantages of the utility model are:

1. Since the utility model has a through hole in the middle of the mounting plate welded together with the circuit board, and the aperture on the side in contact with the circuit board is smaller, when the solder passes through the above through hole and the circuit board is firmly welded , the solder joints position the upper, lower, front, rear, left, and right positions of the mounting plate. Even if the solder joints and the mounting plate are not welded firmly, the tapered solder joints can still play a better positioning role.

2. The S-shaped terminal used in the utility model makes the elastic deformation range of the terminal larger, and the stored elastic energy is also larger, so that the electrical connection performance of the terminal is good.

3. The utility model is suitable for various types of electrical connectors.

Detailed ways:

The utility model is described further below with specific embodiment:

See Figure 1-7: an electrical connector, including a housing 10 and a terminal 20, the terminal 20 is inserted into the mounting groove 102 of the housing 10, and the upper part of the terminal 20 is characterized in that the upper part of the terminal 20 is an S-shaped external The contact part 201, the outer end of the S-shaped external contact part 201 is a protruding protrusion 2011, the lower part is connected with the horizontal welding leg 202, and the outer surface of both sides of the housing 10 is provided with a socket 104, which is at a right angle One right-angle plate 303 of the installation plate 30 is inserted into the socket 104, and the middle part of the other right-angle plate 301 of the installation plate 30 is provided with a through hole 2011. The right-angle plate 301 and the welding leg 202 are in the same plane. The support wall 103 on which the welding leg 202 of the connection terminal 20 is placed is a horizontal support wall.

Protrusions 3031 for positioning with the housing 10 are provided on both sides of the right-angled side 303 on the mounting plate 30 inserted into the insertion port 104 , and accommodating protrusions 3031 are correspondingly provided in the insertion port 104 of the housing 10 groove.

The above-mentioned through hole 3011 on the mounting board 30 has a certain taper, and the diameter of the hole on the side in contact with the circuit board is smaller.

Use of the present utility model: first align the welding feet 202 of the present utility model and one side of the right-angle plate 301 with the corresponding wiring on the circuit board, and use solder to connect the right-angle plate 301 and the circuit through the through hole 3011 on the right-angle plate 301 The boards are welded together, and then the welding pin 202 is welded together with the corresponding circuit on the circuit board, and the integrated block 101 or the electric plug can be inserted into the electrical connector from the front, and electrically connected with the corresponding terminal.

The utility model is suitable for various types of electrical connectors.

The above-described embodiment is only one of the preferred embodiments of the present utility model, and is not intended to limit the scope of implementation of the present utility model, so: all equivalent changes made according to the shape, structure and principle of the present utility model should be covered.
