Description

Connector having an interference fit structure to form a waterproof function

The present invention relates to a connector, and more particularly to a connector that achieves a good watertight effect by an interference fit between an insulating base and a terminal block.

Button, the connector refers to all connected components and their accessories on the electronic signal and power supply. It is a bridge for all signals. Its quality will affect the reliability of current and signal transmission, and also with electronics. The operation of the device is closely related. Generally speaking, various types of connectors have been provided on various electronic devices (such as smart phones, tablets, desktop computers, notebook computers, digital cameras, etc.) so that various electronic devices can By exchanging data, it is known that the connector can make electrical connections and signal transmission between the device and the device, components and components, and the system and the system, and is a basic component required to form a complete system.

According to the above, the current general design method of electronic devices is to have a circuit board therein, and the circuit board can be soldered to fix connectors and electronic components so as to be electrically connected to each other, and perform huge data transmission and complicated logic. Operation. However, the creator found that the structure of the insulating seat of the existing connector is mostly formed by combining a body with a terminal block (or a tongue plate), and a plurality of metal terminals can be disposed on the terminal block, wherein the seat body The front side is provided with a front opening to be inserted into the other connector, and the rear side of the seat body is provided with a rear opening so that the terminal block can be inserted into the seat body through the rear opening, but in the foregoing structure , usually between the terminal block and the body There will be some slight gaps, causing moisture or moisture in the air (such as rainwater, beverages, etc.) to enter the electronic device from the rear opening of the body through the gap, resulting in electronic components inside the electronic device. Or the line is rusted or short-circuited due to moisture or moisture, and the moisture or moisture inside the electronic device is not easily emitted, thereby causing the electronic device to easily cause a malfunction or other problem, and the electronic device It can't work normally. In this case, it not only causes great trouble to the user in operation, but also the infiltration of moisture or moisture makes the life of the electronic device greatly reduced.

In order to solve the above problems, many connector manufacturers have successively developed connectors with waterproof functions. For example, the manufacturer uses a waterproof glue at the rear opening of the seat body to seal the terminal block and the entire rear opening together. Area, however, this method not only consumes a lot of waterproof glue, but when the waterproof glue after solidification is broken or damaged, the staff must remove the entire waterproof glue to re-add new waterproof glue, and the manufacturer also In the production process, additional steps such as "infusion of waterproof rubber" and "inspection of solidified waterproof rubber" are added to increase the production cost and production time of the manufacturer. As for other waterproof structures or mechanisms, problems such as complicated design and increased production steps are common, resulting in high manufacturing costs and product defect rates.

According to this, how to design a connector with good watertightness without significantly changing the structure and process of the connector, so as to effectively prevent moisture or moisture from intruding into the interior of the electronic device through the connector, thereby effectively improving The service life of electronic devices has become an important topic for this creation.

Due to the waterproof design of the conventional connector, the process or the structure of the connector is greatly changed. Therefore, the creator has specialized in various power supply or signal connector designs for many years. With rich practical experience in processing and manufacturing, and adhering to the spirit of research excellence, after long-term efforts and research, I finally developed a connector with an interference fit structure to form a waterproof function. It is available to provide a connector that is more convenient and has good waterproofness.

An object of the present invention is to provide a connector having an interference fit structure for forming a waterproof function, comprising an insulating base body, at least one terminal block and a plurality of metal terminals, wherein the insulating seat body is provided with a front side recessed toward the inner side. At least one plug-in space is provided with at least one assembly port on the rear side, and each of the assembly ports can be respectively connected to each of the plug-in spaces through a terminal slot, and each of the terminal blocks is made of an insulating material. And can be embedded in each of the terminal slots through the assembly openings, and the metal terminals can be penetrated by the metal terminals, and the front ends of the metal terminals extend to the insertion space, and the rear ends of the metal bodies are The connector is characterized in that each of the terminal blocks is respectively provided with at least one interference region, and the insulating housing is respectively provided with at least one mating region corresponding to each of the terminal slots, and each of the interference regions The cross-sectional width is greater than the cross-sectional width of each of the corresponding mating regions.
