Description

USB AF full plastic double-layer board

technical field

The utility model belongs to the technical field of connectors, in particular to a USB AF full plastic double-layer plug board.

Background technique

The USB interface, the Universal Serial Bus, is a serial bus standard connecting computer systems and external devices, and is also a technical specification for input and output interfaces. It is widely used in information communication products such as personal computers and mobile devices. To photographic equipment, digital TV (set-top box), game consoles and other related fields. From the original USB1.0 to 2.0, then to 3.0, and even the latest 3.1, the transmission speed is 10Gbit/s, the three-stage voltage is 5V/12V/20V, the maximum power supply is 100W, and the new Type C plug-in is no longer divided into positive and negative. opposite.

However, up to now, the electronic products used in the market are generally dominated by USB2.0 interfaces, such as computers. At the same time, in specific usage scenarios, there are often situations where multiple USB ports need to be plugged in, such as wireless mice, wireless keyboards, U disks, etc., which are not enough, occupy space for plugging, or require two USB ports at the same time. situation of use.

In order to solve this problem, the Chinese patent 201820021957.8, named "a double-layer connector female seat", installs two USB AF interfaces into one housing, which is convenient for users to use when using double A female. However, since the USB AF interfaces are independent of each other, each has its own casing, and is then fabricated by installing into the upper and lower installation slots in the casing, which occupies a large space, consumes materials, and costs relatively high.

Utility model content

In order to solve the above-mentioned technical problems of occupying a large space and consuming materials, the purpose of the utility model is to provide a USB AF full-plastic double-layer plug board, which can solve the problem of occupying a The problem of large space and material consumption, and the processing technology is simple and fast.

In order to achieve the above-mentioned purpose, the utility model is realized according to the following technical solutions:

The USB AF full-plastic double-layer plug-in board of the utility model comprises a full-plastic shell and a plurality of AFs with two sets of USB AF interfaces.

connection terminal; the all-plastic shell is provided with two installation grooves for installing the AF connection terminal, and the installation groove

The upper and lower layers are distributed.

Further, one end of the installation groove located at the AF connection terminal is a T-shaped groove.

Further, the T-shaped grooves are provided in several and arranged horizontally.

Further, the width dimension of the AF connection terminal used as the positive and negative electrodes of the power supply is larger than that of the other AF connection terminals.

Further, a side portion of the all-plastic housing is provided with through holes for heat dissipation.

Further, the through hole is located near one end of the AF connection terminal.

Further, the through hole is arranged parallel to the direction of the AF connection terminal.

Compared with the prior art, the beneficial effects of the present utility model are:

In the USB AF all-plastic double-layer plug-in board of the present invention, the all-plastic shell is formed by pre-forming the installation grooves of the AF connection terminals of the two USB AF interfaces to be installed at one time, so that only the AF connection terminals need to be installed. The production can be completed by inserting it into the corresponding installation slot, and the processing technology is simple and fast.

At the same time, because the outer shell is shared with the shell of the USB AF interface installed inside, and is pre-integrated, the overall space is greatly reduced and the raw materials are reduced. In the case of meeting the use of two USB AF interfaces at the same time, Its production cost is low and the price is more affordable.

Detailed ways

The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, but not to limit the present utility model.

As shown in FIG. 1-FIG. 3, the USB AF full-plastic double-layer plug-in board according to the present invention includes a full-plastic shell 1 and two groups of several AF connection terminals 2, and the full-plastic shell 1 is provided with a mounting plate. Slot 11. The all-plastic housing 1 has pre-made installation grooves for the two sets of AF connection terminals 2 installed in it, and is integrally formed, so that the production can be completed by simply inserting the AF connection terminals into the corresponding installation grooves. The processing technology is simple and fast.

At the same time, because the outer shell is shared with the shell of the USB AF interface installed inside, and is pre-integrated, the overall space is greatly reduced and the raw materials are reduced. In the case of meeting the use of two USB AF interfaces at the same time, Its production cost is low and the price is more affordable.

Wherein, the installation groove 11 is used for installing the AF connection terminal 2, and the installation groove 11 is designed in two upper and lower layers. This design is different from the horizontally arranged design, which can save the horizontal occupied area and does not hinder the convenient plug-in port to plug in other devices.

The installation slot 11 is located at one end of the AF connection terminal 11 and is designed with a T-shaped groove, which plays the role of positioning, centering and stopping the AF connection terminal 11 inserted into it, thereby ensuring the firmness and stability of the installation. It improves the safety performance and quality of the entire USB AF full-plastic double-layer plug-in board. Wherein, several T-shaped grooves are provided and arranged horizontally to match the design structure of the USB AF interface.

Further, among the AF connection terminals 2, which are used as the positive and negative electrodes of the power supply, their widths are larger than the other ones, which play a role of stable and fast transmission of excessive current.

Further, in order to facilitate heat dissipation of the AF connection terminal 2 during power-on use, a side portion of the all-plastic housing 1 is provided with a through hole 12 for heat dissipation. Preferably, the through hole 12 is located near one end of the AF connection terminal 2 . Further preferably, the through hole 12 is arranged parallel to the direction of the AF connection terminal, and the heat dissipation effect is better.

It should be noted that: the USB AF all-plastic double-layer plug-in board according to the present utility model can also be arranged into three layers, four layers, or even more layers according to the above principles and structures, which all belong to the protection scope of the present utility model. .

For other structures of the USB AF full-plastic double-layer plug-in board of the present invention, refer to the prior art, which will not be repeated here.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. Therefore, without departing from the technical solution content of the present utility model, the above embodiments are made according to the technical essence of the present utility model. Any modification, equivalent change and modification of the present invention still belong to the scope of the technical solution of the present invention.
