Assembly process that does not damage plastic components with wire connectors

The invention relates to an assembly process of a wire connector, in particular to a welding operation of a metal component in a wire connector, and then into a plastic component to avoid damaging the assembly of the plastic component of the wire connector. Process.

According to various electronic systems, connectors are electrically connected and signaled between devices and devices, components and components, systems and systems, and are the basic components required to form a complete system. Therefore, the manufacturer Can increase its own market competitiveness, do not strive to separate the design or optimization of the detailed structure of each part of the connector, in order to increase the modular flexibility of each part, and meet the functional and structural requirements of the connector, in general, For ordinary users, various computer products such as desktop computers, notebook computers or tablet computers are almost daily products. Therefore, all major players are dedicated to the various specifications or models of connectors on computer products. Improved to get the favor of consumers.

Check that the front and rear sides of the host computer of the existing desktop computer usually have multiple connectors, such as: USB, PS/2, RJ45, DVI, HDMI, etc., the user can keyboard, mouse The transmission line of the peripheral device such as a screen is plugged into the corresponding connector to operate the desktop computer by each peripheral device. However, due to the large size of the host, the distance between the front and rear sides thereof is Longer, because the board of the mainframe is usually located closer to the back side, most of the operators will adopt the design of the cable connector to take advantage of the wire length of the cable connector, so that it can be located on the front side of the host. The connector on the panel can be electrically connected to the circuit board to transmit signals or power. However, as shown in FIG. 1 , when the cable connector 1 is to be fixed on the panel of the electronic device, It is usually sufficient to weld a plurality of metal components to assemble the cable connector 1 to the panel. However, since the cable connector 1 is mainly assembled by an insulating base 11 and a metal casing 13, Wherein, the insulating seat 11 Subject Usually, it is a plastic material and is assembled in the metal casing 13. Therefore, when each of the metal components is welded to the metal casing 13, the high temperature generated by the welding operation is conducted through the metal casing 13. Up to the insulating base 11, the insulating base 11 is melted and deformed and damaged, so that the strip connector 1 cannot be normally connected to other connectors.

In summary, the existing line connector will still cause damage to some components and reduce the production yield in the production process. Therefore, in order to occupy a place in the connector market, the relevant operators are all indispensable. Separate design or optimization of the detailed structure of each part of the connector to improve its own market competitiveness. Therefore, how to improve the aforementioned defects and provide a new assembly process of the connector, that is, the present invention This is an important issue to be solved.

In view of the assembly process of the conventional wire connector, the plastic components on the wire are damaged due to the welding operation. Therefore, the inventor finally designed the product after many years of practical experience and after many experiments and tests. An assembly process of the present invention which does not damage the plastic component of the wire connector can effectively improve the aforementioned defects.

It is an object of the present invention to provide an assembly process for a plastic component that does not damage the cord connector, the strap connector including a fixed housing, a positioning housing, a connector body and an upper housing, wherein The front and rear ends of the fixed housing communicate with each other to form a first receiving space, and an upper opening is defined in a top portion thereof. The front and rear ends of the positioning housing communicate with each other to form a second receiving space, and the front end thereof The peripheral edge is provided with a plurality of positioning pieces, and the positioning pieces can be vertically fixed to an electronic device. The connector system is made of plastic material, and a plurality of connecting terminals are arranged at the front end to form at least one plug connector, and thereafter The end of the assembly is provided with a transmission line, the assembly process is first sleeved on the front end of the fixed housing, so that the fixed housing is placed in the second receiving space, and the positioning housing does not cover The upper opening, 嗣, welding the positioning housing to the fixed housing, and then inserting the connector body into the first receiving space of the fixed housing, and the plug connector Correct At the front end of the fixed housing, the transmission line extends from the rear end of the fixed housing, and finally, the upper housing is snap-fitted to the position of the fixed housing corresponding to the upper opening to shield the upper portion. Opening the connector body to form the strip connector; thus, since the fixed housing and the positioning housing are first welded After the operation, the connector body is placed in the fixed housing. Therefore, when the cable connector is vertically fixed in the electronic device through the positioning housing, not only the fixed housing but also the positioning The joint strength between the shells can be maintained by welding, and the high temperature generated by the welding operation does not melt the plastic of the connector body, thereby destroying the structure of the connector body, so that the belt connection can be effectively improved. The yield of the device in production and assembly.

A second object of the present invention is that the wire connector further includes a metal frame, and the front and rear ends of the metal frame communicate with each other to form a through space, after the positioning housing is welded and assembled to the fixed housing. Then, the metal frame is sleeved to the front end of the fixed casing so that the front end of the fixed casing can extend into the through space, and then the positioning shell is welded and assembled to the fixed casing by welding. Finally, the connector body and the upper housing are sequentially assembled to the fixed housing, such that the positioning housing and the metal frame are not inserted into the first receiving space before the connector body is inserted into the first receiving space. That is, it has been separately welded and fixed to the fixed casing to complete the required welding work, so that the plastic component on the connector body is not damaged due to high temperature melting.
