Description

Plug connector and connector group capable of enhancing connection retention

This creation relates to a connector group, especially a connector group provided with a stepped surface on a plug unit of a plug connector.

With the advancement of communication technology and electronic technology, electronic devices with various functions, such as: mobile power devices that can be carried around for continuous power supply of mobile phones, mobile phones that allow people to communicate at both ends of the world, can meet people anytime, anywhere Walkmans that listen to music and personal computers that can help people deal with everything have become indispensable tools in the lives and work of modern people.

In addition, various electronic devices (such as smart phones, tablet computers, desktop computers, notebook computers, digital cameras, etc.) in order to be able to receive electronic signals and power from outside, usually must be There is a signal connector on the fuselage. Generally speaking, a connector refers to all the connecting elements and their accessories used in electronic signals and power supplies. It is a bridge for all signals, and its quality will affect the transmission of current and signals. Reliability has an impact and is also closely related to the operation of the electronic device. Also, through the function of the signal connector, it is possible to connect a plurality of electronic devices into a complete system, according to which electronic signals or power supplies are transmitted to each other, so it can be seen that the signal connector It is an indispensable element for the electronic device to realize a predetermined function.

With the change of usage and installation location, there are many different types of connectors to adapt to meet the needs of use, for example, the connector products shown in Figure 1 (US Patent No. 7,086,870 ), the plug terminal 11 of the plug connector is cylindrical, and when the plug terminal 11 is inserted into the socket 12 of a socket connector, the claw-shaped element 13 in the socket 12 will clamp the plug terminal 11, However, the inventor found that since the plug terminal 11 as a whole is smooth and has no step difference, the plug connector and the receptacle connector can only be held by the gripping force of the claw-shaped element 13 itself. For long-term use, the aforementioned structure is prone to loosening or insufficient gripping force of the claw-shaped element 13, especially for the wire-to-wire type connector group, because of its long length, It is easier for the plug connector and the socket connector to separate from each other when the user does not pull or collide during use.

According to the above, there are currently some wire-to-wire type connector groups, which are the nature of extended length connectors. Therefore, after the plug connector and the socket connector are inserted, there is no need to separate the two, as As mentioned above, simply by the gripping force of the claw-shaped element 13 can not meet the needs of the connector group that needs to be stably inserted for a long time. Therefore, how to effectively solve the aforementioned problem without the need to add an excessive fixing mechanism, resulting in the connector group The organization is too complicated, and it becomes one of the important topics in this creation.

In view of the improvement of the conventional connector, the creator has designed a kind of the present invention after many years of research and testing with rich practical experience in designing, developing and manufacturing various signal connectors. The plug connector and its connector group, which can strengthen the connection retention, are expected to provide a connector structure that can better meet the needs of use.

One purpose of this creation is to provide a plug connector capable of enhancing connection retention, wherein the front section of the plug connector is cylindrical to form a plug unit, and a part of its outer edge is covered with an insulating layer. The characteristic of the creation is that the plug unit is composed of at least a cylinder and a cylinder head, wherein the cylinder head is located at the front end of the cylinder body, and the outer diameter of the rear end of the cylinder head is larger than the front diameter of the cylinder body The junction between the column head and the column body forms a difference surface. When the plug connector is plugged into a socket connector, the column body can be grasped by the rear end of a claw-shaped sleeve in the socket connector , And the difference surface will be located behind the rear end of the claw-shaped sleeve. When the plug connector is forced to move away from the socket connector, the difference surface can abut the rear end of the claw-shaped sleeve, so that the column The body cannot be separated from the claw-shaped sleeve. Therefore, with the design of the segmented surface, the manufacturer can greatly improve the stability of positioning the plug connector on the socket connector without significantly changing the structure of the plug connector.

Another object of this creation is to provide a connector set capable of enhancing connection retention, including a plug connector, a socket connector and a claw-shaped sleeve, wherein the front section of the plug connector is cylindrical, In order to form a plug unit, a part of the outer edge is covered with a plug insulation layer, the front section of the socket connector is groove-shaped and is provided with a plug-in space to form a socket unit, and a part of the outer edge is covered with a socket Insulating layer, the claw-shaped sleeve will be located in the insertion space, including a ring body and a plurality of claw bodies, the front ends of the claw bodies are connected to the rear end of the ring body, and the rear ends of the claw bodies face the claws The axial direction of the sleeve is gathered; the characteristic of this creation is that the plug unit is composed of at least a cylinder and a cylinder head, wherein the cylinder head is located at the front end of the cylinder body, and the rear diameter of the cylinder head is greater than The outer diameter of the front end of the column body forms a difference surface at the junction of the column head and the column body. In the state where the plug connector and the socket connector are both connected, the column head will be formed by the The front end of the claw-shaped sleeve extends in and passes through the ring body and the claw bodies in sequence, so that the cylinder of the plug unit is grasped by the claw bodies, and the difference surface will be located on the claw body In the rear position, when the plug connector is forced to move away from the socket connector, the difference surface will abut against the rear ends of the claw bodies, so that the column body cannot be separated from the claw-shaped sleeve, so it can be effectively Strengthen the connection retention between the plug connector and the socket connector.
