Description

A side-plug horizontal female connector

Technical Field

The utility model relates to the technical field of electrical connection devices, in particular to a connector used for realizing electrical connection between electronic devices.

Background Art

Many products require electrical connection between electronic devices through the plug-in of connectors to achieve the purpose of power supply, signal transmission, etc., such as transportation tools, energy storage products, etc. In the prior art, the flat male terminal of the horizontal connector is generally inserted into the female terminal in a flat and horizontal manner. When the male terminal is flat, based on factors such as the habit of human hand force, the uneven distribution of plug-in and pull-out forces in different parts will increase due to the flat and horizontal insertion of the female terminal. This may cause some contact points to bear excessive pressure, accelerate their wear and damage, and when the frequently plugged and unplugged connector is inserted into or unplugged from the interface, the uneven plug-in and pull-out force will shorten its service life and reduce the reliability of the connection, which is more obvious when passing large currents. In order to solve the impact caused by uneven plug-in and pull-out forces, it is generally necessary to design auxiliary support structures with more complex structures, such as various limit and positioning structures. At the same time, similar connectors currently generally only clamp the male terminal through the elastic force of the female terminal itself, the clamping force is not high enough, the contact is not tight enough, and the contact surface between the female terminal and the male terminal is small, which will affect the reliability when passing large currents. In addition, when the pressure on the female terminal is too great, there is a risk that the female terminal may not be able to rebound.

Utility Model Content

The utility model aims to solve the defects in the prior art that the contact surface between the female terminal and the male terminal is small and the clamping force is not strong enough, which will affect the performance of passing large currents. It provides a side-plugging horizontal female-end connector with a simpler structure, a more reasonable design, and the ability to improve the uniformity of the plugging and unplugging force, thereby making the plugging reliability higher.

In order to solve the above technical problems, the utility model adopts the following technical solutions: a side-plugging horizontal female-end connector, comprising a female-end shell and a female terminal, the female-end shell having a plug-in channel inside, and a plurality of female terminals arranged along the vertical direction on the inner walls on both sides of the plug-in channel; each female terminal extends from the front end of the female-end shell, bends backward and penetrates into the plug-in channel to form a relative clamping structure, and the male terminal is inserted between the left and right female terminals and clamped by the female terminals; a protrusion is provided on the inner side wall of the female-end shell, the protrusion is opposite to the tail end of each female terminal, and the tail end of each female terminal extends obliquely toward the protrusion but leaves a gap, and after the male terminal is inserted, the tail end of the female terminal is squeezed until it is supported by the protrusion.

Furthermore, a plug pin and an auxiliary pin are provided at the bottom of the female end housing. The plug pin extends downward to form a structure for plugging and fixing with the board end, and the auxiliary pin extends outward to form an L-shaped structure and supports the surface of the board end.

Furthermore, a raised pad is provided on the surface of the plate end opposite to the auxiliary foot, and the bottom of the auxiliary foot is pressed on the pad and fixed by welding to form left and right auxiliary supports and a power-on structure for the female end shell.

Preferably, the female terminals are of W-shaped or wavy structure, and the two rows of female terminals are symmetrical.

Furthermore, the top of the female shell is a docking portion, a dovetail groove is provided on one side of the docking portion, and a dovetail-shaped clamping portion is provided on the other side. The clamping portion is inserted into the dovetail groove so that the left and right sides of the top of the female shell are combined and fixed to each other.

Furthermore, the protrusion is formed into a structure protruding toward the inside of the female end shell by stamping.

Preferably, the female terminal is formed by stamping, and the female terminal and the female terminal housing are an integral structure.

Furthermore, the plug pins and the auxiliary pins are formed by stamping or punching, and the plug pins and the auxiliary pins are an integral structure with the female end housing.

The utility model can significantly reduce the problem of uneven distribution of plugging and unplugging force, make the plugging reliability higher, and reduce the size of the entire connector, thereby reducing the area occupied on the board end, by arranging a number of elastic female terminals arranged in a vertical direction on both sides of the female end shell channel to cooperate with the clamping of the male terminal inserted horizontally in a side-standing posture. At the same time, a raised portion is arranged on the inner wall of the female end shell, so that the inserted male terminal can be more closely contacted, ensuring more sufficient multi-point contact and a larger contact area to stably pass large currents and prevent the female terminal from being subjected to excessive pressure and unable to rebound. In this way, the utility model can play a buffering and shock-absorbing role in a vibrating working environment, such as when used inside a car.

DETAILED DESCRIPTION

In this embodiment, referring to FIGS. 1 to 3 , the side-plug horizontal female connector comprises a female housing 1 and female terminals 2. The female housing 1 is made of conductive metal, such as a copper sheet. The female housing 1 has a plug-in channel inside. A plurality of female terminals 2 (for example, four) are arranged vertically on the inner walls of the plug-in channel on both sides, and the female terminals 2 are aligned left and right. Each female terminal 2 extends from the front end of the female housing 1, bends backward and penetrates into the plug-in channel to form a clamping structure opposite to the left and right. The male terminal 9 is inserted between the left and right female terminals 2 and clamped by each female terminal 2. In this way, it is easier to apply force when the female terminal is inserted horizontally in a side-standing posture, thereby maintaining the uniformity of the plug-in force. A protrusion 5 is provided on the inner side wall of the female housing 1. The protrusion 5 is opposite to the tail end of each female terminal 2. The tail end of each female terminal 2 extends obliquely toward the protrusion 5 but leaves a gap. After the male terminal 9 is inserted, the tail end of the female terminal 2 is squeezed until it is supported by the protrusion 5, so that the female terminal 2 has the potential energy to move toward the middle. This helps to make the wave high point near the tail end of the female terminal 2 closely contact with the inserted male terminal 9, ensuring more complete multi-point contact to stably pass large currents, while preventing the female terminal 2 from being subjected to excessive pressure and unable to rebound.

A plug pin 3 and an auxiliary pin 4 are provided at the bottom of the female end housing 1. The plug pin 3 extends downward to form a structure for plugging and fixing with the board end 7, and then welded and fixed after plugging; the auxiliary pin 4 extends outward to form an L-shaped structure and supports the surface of the board end 7. Such a symmetrical arrangement on both sides can prevent the female end from being unstable and tilting to both sides after the plug pin 3 is inserted into the socket of the board end 7, thereby ensuring the stability of the connector during the welding process and subsequent use.

A raised pad 8 is provided on the surface of the plate end 7 at a position opposite to the auxiliary foot 4. The bottom of the auxiliary foot 4 is pressed on the pad 8 and welded and fixed to achieve auxiliary support for the left and right sides of the female end shell 1 and is used to transmit current, thereby improving the ability to pass large currents.

The female terminals 2 are of a wave-shaped structure (or a W-shaped structure), and the two rows of female terminals 2 are symmetrical, which can increase the electrical contact area, increase the passing current, and increase the friction force to provide a greater clamping force.

The top of the female end shell 1 is the docking part, a dovetail groove is provided on one side of the docking part, and a dovetail-shaped clamping part 6 is provided on the other side. The clamping part 6 is inserted into the dovetail groove so that the left and right sides of the top of the female end shell 1 are combined and fixed to each other, with a simple structure and a stable combination.

The protrusion 5 is formed into a structure protruding toward the inside of the female housing 1 by stamping.

The female terminal 2 is formed by stamping, and the female terminal 2 and the female terminal housing 1 are an integral structure.

The plug pin 3 and the auxiliary pin 4 are formed by stamping or punching, and the plug pin 2 and the auxiliary pin 3 are an integral structure with the female end housing 1.

The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
