Therefore, how to avoid the contact short circuit between the upper and lower rows of terminals and the middle shield plate becomes the biggest problem in the production process. Some manufacturers fix the upper and lower rows of terminals through process positioning, and then fill the space between the upper and lower rows of terminals and the middle shielding plate with plastic. However, during the plastic filling process, it is impossible to completely monitor and inspect the deformation of the upper and lower rows of terminals. Some manufacturers also reduce the risk of short circuit by reducing the area of the upper and lower rows of terminals, but it cannot be completely avoided, and there are still risks of failure and potential safety hazards.

Referring to FIG. 1 , it shows an electrical connector interface in an embodiment of the present invention, the electrical connector interface includes an upper row of terminals 101, a lower row of terminals 102, a terminal located between the upper row of terminals 101 and the lower row of terminals. The middle partition 103 and the housing 104 between 102;

The housing 104 fixes the upper row of terminals 101, the lower row of terminals 102 and the middle partition 103;

The upper row of terminals 101 and the lower row of terminals 102 are connected at an end close to the housing 104;

The surface of the middle partition 103 is covered with insulating material, or the middle partition is made of insulating material.

In this embodiment, the electrical connector interface may include a USB tpyeC interface. The USB tpyeC interface has many advantages: First, it is fast. The maximum transmission rate of the USB tpyeC interface is 10Gb per second, while the limit transmission rate of the USB tpyeA so far is 5Gbps. The second is multi-functional, the USB tpyeC interface can transmit data, charge and can also be used as a video output port to connect to an external display device. The third is that it can realize two-way transmission. The power transmission of the USB tpyeC interface is two-way. There are two ways to transmit power. Users can not only use notebooks to charge mobile devices, but also use other devices or mobile power sources to charge notebooks.

The electrical connector interface (USB tpyeC interface) includes an upper row of terminals 101 , a lower row of terminals 102 , a middle partition 103 between the upper row of terminals 101 and the lower row of terminals 102 , and a housing 104 . The housing 104 fixes the upper row of terminals 101 , the lower row of terminals 102 and the middle partition 103 . The function of the upper row of terminals 101 is to connect power, ground and data signals, etc., and each terminal of the lower row of terminals 102 corresponds to the upper row of terminals 101 one by one, so the upper row of terminals 101 and the lower row of terminals 102 are connected at the end close to the housing 104 . The middle partition 103 is located between the upper row of terminals 101 and the lower row of terminals 102 to act as a partition to prevent the upper row of terminals 101 and the lower row of terminals 102 from contacting and short circuiting. Wherein, the surface of the middle partition 103 is covered with insulating material, or the middle partition 103 is made of insulating material, see the schematic diagram of the middle partition shown in FIG. 2 . The embodiments of the present invention do not limit the shape of the intermediate partition in detail, and may be set according to actual conditions. Since the surface of the middle partition 103 is covered with an insulating material, or the middle partition 103 is an insulating material, even if the upper row of terminals 101 or the lower row of terminals 102 contacts the middle partition, there will be no short circuit between the terminals and the middle partition, so as to avoid Problems such as burn-in caused by the short circuit between the terminal and the middle partition are eliminated.

Preferably, an electrophoresis (electrophoresis, EP) process may be used to cover the surface of the middle partition 103 with an insulating material. Specifically, under the action of an external DC power supply, the colloidal particles of the insulating material move toward the middle partition and adhere to the surface of the middle partition. The electrophoresis process has the advantages of full, uniform, smooth and smooth coating. The hardness, adhesion, corrosion resistance, impact performance and permeability of the insulating layer covered by the electrophoresis process are significantly better than other coating processes.

In this embodiment, the insulating material may be acrylic resin. Acrylic resin has good voltage resistance performance, which can effectively isolate the general external current from the product. At the same time, it has good compactness, and can effectively isolate metal from air, water, electrolyte and other corrosive media. The conditions for corrosion to occur are insufficient, and it plays a preventive role.

In a preferred embodiment of the present invention, the distances between the upper row of terminals 101 and the lower row of terminals 102 and the middle partition 103 are both 0.15 mm.

In this embodiment, the distance between the upper row of terminals 101 and the lower row of terminals 102 and the middle partition 103 can be set to 0.15mm, so that the upper row of terminals 101 and the lower row of terminals 102 do not contact the middle partition 103, further avoiding the Burn-in problem caused by contact with the middle partition and short circuit.

In a preferred embodiment of the present invention, the upper row of terminals 101 and the lower row of terminals 102 are respectively provided with 12 pins.

Specifically, the upper row of terminals 101 includes GND, TX1+, TX1-, V _BUS , CC1, D+, D-, SUB1, V _BUS , RX2-, RX2+, GND; the lower row of terminals 102 correspondingly include GND, RX1+, RX1-, V _BUS , SUB2, D-, D+, CC2, V _BUS , TX2-, TX2+, GND. TX and RX are two sets of differential signals for data transmission; the functions of CC1 and CC2 include detecting connections, distinguishing front and back, configuring V _BUS and so on. There are 4 power supply V _BUS and ground GND, which can support 100W; D+ and D- are used to be compatible with the previous USB standard. Since the 12 pins of the upper row of terminals 101 correspond to the 12 pins of the lower row of terminals one by one, the electrical connection interface can realize the function of electrical connection regardless of whether it is inserted forward or reversed, which solves the problem of "USB is always inaccurate". The problem.

In summary, in the embodiment of the present invention, the electrical connector interface includes an upper row of terminals, a lower row of terminals, a middle partition between the upper row of terminals and the lower row of terminals, and a middle partition; the surface of the middle partition is covered with insulating material, or the middle partition is insulating material. Because the surface of the middle partition is insulated, even if the molding pressure is too high during the injection molding process, causing the terminal arch to contact the middle partition, there will be no short circuit between the terminal and the middle partition, which avoids the phenomenon of contact between the terminal and the middle partition Burn-in and other problems caused by short circuit.

The surface of the middle partition 103 is covered with insulating material or the middle partition is made of insulating material. Various techniques can be used to cover the surface of the intermediate partition 103 with insulating materials, such as spraying, electrophoresis, and the like. Specifically, the insulating material is covered on the surface of the middle partition 103 by electrophoresis technology, and the colloidal particles of the insulating material move toward the middle partition 103 and adhere to the surface of the middle partition 103 under the action of an external DC power supply. The insulating layer covered on the middle partition 103 by electrophoresis is plump, uniform, flat and smooth.
