Description

USB connector structure

Technical Field

The utility model relates to the technical field of electronic connectors, in particular to a USB connector structure.

Background

A USB connector is a very common electronic connector, and is mainly used for connecting electronic devices, supplying power to the electronic devices or transmitting data. The existing USB connector mainly comprises an insertion end and a handheld end, wherein the insertion end is a plastic part wrapped by an iron shell, and a terminal is arranged on the plastic part. The holding end is a plastic outer mold which is injected at one end of the iron shell, and the plastic outer mold fixes the wire and the inserting end.

Because the plastic outer mold and the iron shell in the conventional USB connector are fixed only by the adhesive force of the plastic, after the USB connector is used for a period of time, the adhesive force between the plastic outer mold and the iron shell can be reduced or failed, the plastic outer mold can be loosened and cracked to cause the plastic outer mold to be separated from the iron shell, and the welding point between the cable and the terminal can be loosened when the external force is pulled, so that the whole USB connector is damaged and fails.

Accordingly, there is a need for a USB connector structure that can improve the durability of the USB connector and prevent the plastic outer mold from falling off the iron shell.

In order to achieve the above purpose, the utility model adopts the following technical scheme.

The utility model provides a USB connector structure, which comprises a head part and a tail part, wherein the head part comprises a plastic body, a metal terminal arranged in the plastic body and an iron shell sleeved outside the plastic body, the tail part comprises a plastic outer mold coated at one end of the iron shell, at least one glue inlet opening is formed in the iron shell, and the plastic outer mold is clamped and fixed with the iron shell by being clamped in the glue inlet opening.

Preferably, the front surface and the back surface of the iron shell are respectively provided with two glue inlet openings.

Preferably, the glue inlet opening is rectangular, and the long side of the rectangle is perpendicular to the length direction of the plastic outer die.

Preferably, a first gap is reserved between the iron shell and the plastic body, and the first gap is communicated with the glue inlet opening.

Preferably, the plastic body is provided with a plurality of ribs, and the ribs are disconnected at the glue inlet opening to form a second gap.

Preferably, the head is a USB-a male head.

The iron shell is provided with at least one glue inlet opening, so that glue can flow into the glue inlet opening when the plastic outer mold is injected, the fixed connection performance between the formed plastic outer mold and the iron shell can be enhanced by the glue in the glue inlet opening, the connection between the plastic outer mold and the iron shell is more stable, the plastic outer mold is not easy to fall off from the iron shell, and the service life of a product can be greatly prolonged.

Detailed Description

The following further description is made with reference to the drawings and specific embodiments.

As shown in fig. 1, the present embodiment provides a USB connector structure 100, including head 10 and afterbody 20, head 10 includes plastic body 11, sets up metal terminal 12 in plastic body 11 and locates with the cover iron casing 13 outside plastic body 11, afterbody 20 including the cladding in the plastic external mold 21 of iron casing 13 one end, be provided with at least one on the iron casing 13 and advance gluey opening 131, plastic external mold 21 is through the card income in the gluey opening 131 with iron casing 13 joint is fixed. The head 10 is a USB-a male plug, a USB-a female plug, or a TYPE-C plug, and the structure, function, and features of the present invention are described in detail in this embodiment by taking a USB-a male plug as an example.

The plastic outer mold 21 is used for wrapping the plastic body 10 and the metal terminal 12 inside, and is also used for bonding with the iron shell 13 to provide a required pushing force or pulling force for plugging and unplugging the USB connector. Because the plastic outer mold 21 is coated on one end of the iron shell 13 through an injection molding process, during injection molding, the fluid colloid 22 flows into the iron shell 13 through the colloid inlet 131, and after the colloid 22 is cooled and molded, the colloid 22 positioned in the colloid inlet 131 is connected with the plastic outer mold 21 outside the iron shell 13 into a whole, so that a tighter connecting structure is formed with the iron shell 13, and not only can a stronger adhesive force be provided for the iron shell 13, but also the connecting structure can generate a larger pulling force, so that the plastic outer mold 21 cannot be loosened due to an overlarge stress. The front and back surfaces of the iron shell 13 of this embodiment are respectively provided with two glue inlets 131 (as shown in fig. 2 and 3), so that when the plastic outer mold 21 is injected, the glue 22 can enter the inside of the iron shell 13 from the front and back surfaces (as shown in fig. 4), thereby further increasing the tightness of the connection between the plastic outer mold 21 and the iron shell 13, and preventing the plastic outer mold 21 from falling off from the iron shell 13.

In this embodiment, the glue inlet 131 is rectangular, and the long side of the rectangle is perpendicular to the length direction of the plastic outer mold 21. When the length of the connection between the plastic outer die 21 and the iron shell 13 is not large, the structure can also ensure the tightness of the connection between the plastic outer die 21 and the iron shell 13.

Referring to fig. 5, a first gap 14 is left between the iron shell 13 and the plastic body 11, and the first gap 14 is communicated with the glue inlet 131. Meanwhile, the plastic body 11 is provided with a plurality of ribs 111, and the ribs 111 are disconnected at the glue inlet 131 to form a second gap 15. The first gap 14 and the second gap 15 can allow the glue 22 to flow in when the plastic outer mold 21 is injection molded, so as to form a relatively large stopper, which can prevent the plastic body 11 from being pulled out by external force, thereby increasing the reliability of the product. On the other hand, the tightness of the connection between the plastic outer mold 21 and the iron shell 13 can be enhanced, and the plastic outer mold 21 can be further prevented from falling off from the iron shell 13, thereby further enhancing the durability of the product.

In summary, the at least one glue inlet opening is formed in the iron shell, so that when the plastic outer mold is injection-molded, the glue can flow into the glue inlet opening, and the fixed connection performance between the molded plastic outer mold and the iron shell can be enhanced by the glue in the glue inlet opening, so that the connection between the plastic outer mold and the iron shell is more stable, the plastic outer mold is not easy to fall off from the iron shell, and the service life of the product can be greatly prolonged.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
