Description

Connector and its clamping device

This creation is about universal serial bus connectors, especially the USB type-C connector and its sandwich structure designer.

Universal Serial Bus (USB) connector is one of the commonly used connector types. It is developed by USB Associationer Forum Inc. (USB-IF) and has experienced USB1.0 so far. With the development of multiple versions such as USB2.0 and USB3.0, the USB type-C transmission protocol with higher transmission speed is now being developed. The USB type-C focuses on the current trend of thin and light product design, and the overall shape is miniaturized. Designed and easy to carry to meet the application needs of mobile products.

In order to ensure that the male connector of the electrical connector is mated with the female seat, the internal contact terminals of the two can be firmly contacted to form an electrical connection, so that a clamping mechanism such as a pair of elastic pieces is disposed outside the connector to avoid The male and female seats are loosened by external forces. Therefore, the clamping mechanism is an essential component that is indispensable to the electrical connector.

However, when the USB type-C connector is manufactured, it is necessary to separately mold a plurality of different assembly structures and assemble the components such as the conductive terminals and the clamping mechanism, thereby complicating the structure and increasing the manufacturing cost. Moreover, the electrical connectors are improved. A plurality of terminals and a pair of elastic pieces are respectively disposed in the connector, which makes the assembly more difficult and makes the machine and the process more complicated. Again, zero group Parts are constantly being required to reduce the size of each part, thus causing the size of the connector parts to be weak, especially when the miniaturized connector male and female are docked with each other. Therefore, the existing electrical connector obviously has much room for improvement.

In the increasingly complex circuit layout and the increasing functionality, the stability and ease of use of data transmission are also urgent. If there are suitable and practical components, the following positive benefits can be achieved:

First, it can reduce the damage of equipment caused by user's negligence.

Second, simplify the production process, and thus reduce production costs.

Third, maintain the stability of data transmission.

Therefore, the main purpose of this creation is to simplify the production process and thus reduce the production cost.

Another purpose of this creation is to strengthen the structure of the connector and to maintain the stability of the transmission signal.

In order to achieve the above object, a connector and a clamping device thereof are provided, which at least comprise an insulating seat having a socket and a clamping device. The insulating base has a slot therein for the external connector to be correspondingly inserted, and the inner wall of the slot is provided with a plurality of terminal slots, and the opposite sides of the insulating seat are respectively recessed with fixing slots for connecting the slots, the clamping device The clamping device can be fixedly connected to the terminal slot by a plurality of terminals, wherein the holding device is embedded with a substrate, and the substrate is integrally formed on both sides and the front end to integrally extend and connect a pair of elastic pieces. And a plug portion for exposing to the outside of the clamping device, thereby achieving the effect of strengthening the overall structure and facilitating assembly.

FIG. 3 is a schematic view showing the combination of the insulating seat and the clamping device of the present invention, and together with other figures, it can be clearly seen from the figure that the present invention mainly comprises a plurality of terminals 21 by the insulating base body 1. The clamping device 2 (as shown in FIG. 3) and one of the left and right sides of a substrate 32 are formed by the elastic piece 3, and the insulating base 1 has an open slot 11 at one end for corresponding insertion of the external connector. The two sides of the inner wall of the slot 11 have terminal slots 12 (such as FIG. 4) for receiving the terminals 21, and a slot 13 is formed between the terminal slots 12 of the two side walls. A fixing groove 14 is defined in each of the recesses, and the fixing groove 14 has a slope and is gradually retracted toward the slot 11 to communicate with the slot 11. The clamping device 2 is configured to hold a plurality of terminals 21 correspondingly disposed in the terminal slot 12, and the terminals 21 in the embodiment are formed by metal stamping and are arranged in two rows, and the size of the terminals 21 of the two rows are set. The dimensions of the terminals of the standard USB Type-C socket electrical connector are the same. The elastic piece 3 is formed by a piece of the substrate 32 extending on both sides to form a pair (such as FIG. 1), and one end of the elastic piece 3 is The clamping portion 31 having a certain curvature can be protruded into the slot 11 via the fixing groove 14 on both sides of the insulating base 1 , and the insertion portion 33 is extended on the front end of the substrate 32 , wherein the substrate 32 further includes A plurality of through holes 321 are directly positioned on the substrate 32 when the clamping device 2 is molded.

The assembly method of the embodiment is that the clamping device 2 of the plastic material is directly molded on the substrate 32 (as shown in FIG. 2), and the clamping device 2 is wrapped on the outside of the substrate 32 so that the insertion portion 33 of the substrate 32 is inserted. And the elastic piece 3 on both sides of the substrate 32 is exposed to the front end and the two sides of the clamping device 2, and then a plurality of terminals 21 are inserted on the clamping device 2 to form two rows of groups, wherein the two rows of terminals 21 are formed. The clamping device 2 can also be integrally molded on the substrate 32, and the clamping device 2 after the casting is directly coated with the substrate 32 and the two rows of terminals 21 (see FIG. 3), and then the above The clamping device 2 for holding the substrate 32 and the terminal 21 is mounted on the insulating base 1 , and at the same time, the elastic piece 3 on both sides of the clamping device 2 can be applied to the elastic piece 3 via the fixing groove 14 of the insulating base 1 The clamping portion 31 protrudes into the slot 11, and the insertion portion 33 at the front end of the substrate 32 is correspondingly inserted into the slot 13 formed in the terminal slot 12 of the inner wall of the insulating base 1 (as shown in FIG. 4). According to the needs of the user, a shielding piece 4 is assembled on the outer side of the insulating base 1 to complete the combination (Fig. 5).

Since the pair of elastic pieces 3 and the insertion portion 33 on the clamping device 2 are integrally formed by direct metal stamping and directly embedded in the clamping device 2, the structure of the clamping device 2 is not only strengthened, but also is saved in production. Since the components are separately opened, assembled, and the like, the manufacturing cost is reduced, and the insertion portion 33 protruding from the front end of the clamping device 2 is inserted into the recess 13 of the insulating housing 1 and may be added. The structure of the insulating base 1 is stable, so that the terminal 21 mounted on the insulating base 1 can be stably fixed to ensure stable signal transmission.

In the longitudinal direction, the present connector and its clamping device are reinforced by the special design of components such as shrapnel, and the manufacturing process is simplified, so that it can be avoided. The product is free from breakage and breakage, and it maintains stable transmission of telecommunication data and reduces production costs. Therefore, it is simpler and more convenient in terms of function and assembly, and it has not been used publicly. According to the provisions of the Patent Law, a new type of patent application is filed according to law, and it is a matter of granting a patent.
