Description

Metal housing with bent welded structure and connector thereof

This creation relates to a metal housing used in a connector, and more particularly to a metal housing having a welded joint at a corner.

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 research, in the past ten years, for many Taiwanese manufacturers entering the connector industry, the connector industry is still a lucrative industry relative to other component industries. The main reason is that In the connector industry, the technology used in high- and low-order connector products is quite different. The aforementioned features make the positioning of related products between international manufacturers and Taiwanese manufacturers extremely clear and clear. In addition, due to the international The various connector products that are commissioned are required to have a wide range of application capabilities. This demanding product requirement also forces Taiwanese manufacturers who have commissioned OEMs to have different specialized projects to avoid The subsequent Red Sea (Chinese related manufacturers) competed.

However, as early as in the decade since 2008, Taiwanese manufacturers who used connectors as their main products have experienced and experienced an industrial crisis. Therefore, many Taiwanese manufacturers at the time clearly recognized that they only rely on the PC industry and are extremely vulnerable to PCs. The industry is sluggish, the barriers to entry are too low, and the industry is fiercely competitive, leading to a survival crisis that cannot continue to operate. Therefore, many Taiwanese manufacturers have adjusted their business strategies and adjusted accordingly. They can use the strategy of multi-transformation to cover the application of connector products to communication or consumer electronic products, such as mobile phones and game consoles... In this way, Taiwanese manufacturers who have relied heavily on connectors for computers and their peripheral devices have turned to the development and production of various consumer electronic products, displays, etc. in recent years. Base connector.

However, as mentioned above, the 2008 financial turmoil has broken the industry tacit understanding that many operators have long followed in the connector industry in Taiwan, such as the US, European and Japanese manufacturers that originally produced high-end or high-end technology connectors. Under the reality of the growing shortage of profits, the consideration began to produce low-end connectors, which seriously invaded the main product line that Taiwan connector manufacturers have mastered for many years. In response to this change in situation, Taiwan connector manufacturers must speed up. Step by step, and add a new strategy to take into account the points and aspects that have not been reviewed in the past, and to explore, develop and improve the various characteristics of the connector to provide better connector products in the industry, so that it is sufficient in the market. To have a role to play.

For example, as an important communication bridge between complex electronic devices, the connector has always been valued for its structural strength and durability, and the manufacturer will repeatedly and repeatedly detect the components of the connector during the production process. The quality, however, the applicant found that during use, because the connector needs to be assembled and plugged with another connector, in general, the plug connector When the direction of the force is parallel to the axis of the connector, in practice, the user does not pay special attention to the insertion angle, so that the connector tends to be non-parallel to the axis of the connector. The external force causes the insulative body of the connector to press the outer metal casing, causing the metal casing to disengage.

In order to solve the aforementioned problems, the applicant has devised a new metal casing to be applied to a connector. For the sake of simplicity, as shown in FIG. 1, the connector 1 includes an insulative body 11 and a plurality of The metal terminal 13 and the metal housing 15 are defined in the housing body 111. The metal housing 13 can be embedded in the insulating body 11 and exposed to the receiving space 111. The metal shell 15 is formed by bending a metal plate, and a mounting hole 152 is defined in a position adjacent to one side of the metal plate. The other side of the metal plate is convexly provided with a latching member 154. When the metal plate is bent After being framed, the assembly space 150 is formed around the front and rear sides to allow the insulative housing 11 to be assembled into the assembly space 150 to form the connector 1. In addition, the metal housing 15 is most unique in that the latching member 154 can pass through the mounting hole 152 from the inner side of the metal housing 15 (ie, corresponding to the assembly space 150), after which the latching member 154 will It is bent and abuts against the outer side surface of the metal casing 15 to form a joint portion 15A, and at the same time, the joint portion 15A is positioned at the corner of the metal casing 15, so that the connector 1 is assembled. Or during use (for example, the action of plugging and unplugging the connector 1), the metal casing 15 can withstand a large external force, and is less prone to deformation or disintegration.

However, the Applicant has found that as the size of the connector is reduced, the step of "the snap member 154 is bent to abut against the outer surface of the metal casing 15" causes difficulty in production and often It is difficult to completely "but" the snap member 154 "on the outer side surface of the metal casing 15," resulting in that the metal casing 15 is not very stable. In view of this, how to effectively improve the aforementioned problems, namely, this initiative A major topic for discussion here.

Due to the metal shell structure previously designed by the applicant, there are still some defects in the production. Therefore, the creator relies on the rich practical experience of designing, processing and manufacturing various power supply or signal connectors for many years. With the long-term research and experimentation, the metal shell and its connector with a bent welded structure have been developed. Through the creation of this creation, the production efficiency is effectively improved. Maintain the structural strength of the connector to provide a better user experience.

One of the purposes of the present invention is to provide a metal casing having a bent welded structure which can be applied to a connector and which is bent and formed by at least one metal plate and is surrounded by the front and rear sides. An assembly space for an insulative body to extend into and be fixed to the assembly space, the metal casing being characterized in that one side of the one end adjacent to the end can be bent and welded to the surface of the other side to be adjacent A welded joint is formed at the corner, so that the metal shell corresponding to the welded joint can be welded in the production process, and the metal shell can be stably held in a form.

Another object of the present invention is to provide at least one engaging hole at a position of one side of the metal plate adjacent to the welded portion, and at least one engaging protruding piece is protruded from the other side of the metal plate, on one side of the metal plate In the state of being welded to the other side surface, the engaging projection piece can protrude into the engaging hole and corresponds to the inner wall surface of the engaging hole.
