Description

Bidirectional double-sided electric connector

Technical Field

The present invention relates to an electrical connector, and more particularly to a two-way dual-sided electrical connector.

Background

Since the functions of various electronic products are becoming more and more powerful and handheld devices are becoming more and more popular, the signal transmission between various products or devices is becoming more and more demanding, wherein the signal transmission between these devices is performed through the signal interface. The signal interface is, for example, an Electrical connector or a complementary Electrical connector mated with the Electrical connector, wherein the Electrical connector is an Electrical connector socket (Electrical plug) and the complementary Electrical connector is an Electrical connector plug (Electrical plug).

Before the electrical connection plug and the electrical connection socket are butted, the electrical connection plug and the electrical connection socket are butted only by directing the electrical connection plug towards the electrical connection socket in a correct direction, that is, the electrical connection socket has a plugging direction, which is commonly called a fool-proof function, and the function is to ensure that a connection interface on the electrical connection plug can be contacted with a contact terminal on the electrical connection socket. However, most users do not have the habit of directing the electrical connection plug to the electrical connection socket in the correct direction, and the foolproof function causes the docking failure between the electrical connection plug and the electrical connection socket, and then the user turns over the electrical connection plug to achieve the correct docking. In other words, the fool-proof function causes the user's trouble.

Therefore, a bidirectional electrical connector with a double-sided mating function is provided in the market, which is provided with two sets of contact terminals to eliminate the plugging direction of the bidirectional electrical connector. The user can mate the bi-directional electrical connector with the complementary electrical connector in either direction. However, the conventional bi-directional electrical connector has high manufacturing cost and low reliability of its function. Therefore, it is a common effort in the industry to provide a bi-directional electrical connector with stable reliability and reduce the cost of the electrical connector.

Please refer to fig. 1A, which is 2018/80044168.9 of the applicant's application, which is a bidirectional double-sided USB TYPE-C3.0 electrical connector provided with two insulating base bodies 10, two rows of terminals 20, a metal partition 30, two grounding pieces 40, and a metal shell 50, wherein:

the insulation base 10 is integrally provided with a base 11 and a butt joint portion 12, the butt joint portion 12 is connected to the front end of the base 11, the two insulation base 20 are vertically overlapped, the inner surfaces of the base 11 of the two insulation base are provided with joint surfaces for abutting, the inner surfaces of the two insulation base 10 are respectively provided with a row of barriers 141 separated into a row of terminal grooves 142 extending forward and backward, the terminal grooves 142 extend from the base 11 to the butt joint portion 12 and can be inserted into terminals from the vertical direction, the butt joint portion 12 is provided with a bottom plate 121 and two side plates connected to the left and right sides of the bottom plate 121, the front section of the inner surface of the bottom plate 12 is provided with a front section surface 144 and the rear section is provided with a rear section surface 143, the rear section surface 143 protrudes a height from the front section surface 144, and a connection groove 125 is formed between the inner surfaces of the bottom plates 121 of the two insulation base.

The two rows of terminals 20 are assembled into the two rows of terminal grooves 142 of the two insulating base bodies 10 in the up-down direction, each terminal 20 is integrally provided with a springing portion 22, a fixing portion 23 and a pin 24 from front to back, the front section 222 of the springing portion is bent and extends upwards in an inclined manner and is provided with a contact portion 221 protruding out of the rear section surface 143, the springing portion 22 can bounce up and down, the rear section 223 of the springing portion and the fixing portion 23 are horizontally abutted to the bottom surface of the terminal groove 142, the depth of the terminal groove 142 is larger than the material thickness of the terminal, so that the rear section 223 of the springing portion and the fixing portion 23 are sunk into the terminal groove 142, the fixing structure 140 is formed by secondary processing of sealing glue corresponding to the position of the fixing portion 23, and the fixing structure 140 fixes the fixing portions 23 of the two rows of terminals 20.

As shown in fig. 1B, when the springing portion 22 of the two rows of terminals is sprung by a force, the rear section of the springing portion of the terminal horizontally abuts against the bottom surface of the terminal slot to have a springing arm middle section supporting effect, i.e. the springing portion is formed with a middle section fulcrum 224 supported by the bottom surface 1421 of the terminal slot, i.e. when the contact portion 221 is sprung toward the bottom surface 1421 of the terminal slot by a force, the rear section 223 of the springing portion behind the middle section fulcrum 224 will bounce in the opposite direction, so that the rear section 223 of the springing portion behind the middle section fulcrum 24 bends and springs to form a gap GP between the bottom surface 1421 of the terminal slot of the base and the rear section 223 of the springing portion, thus increasing the positive force and elasticity of the terminal contact.

The above-mentioned conventional structure has the following disadvantages:

1. as shown in fig. 1B, the inner end 1251 of the connecting slot 125 is located behind the middle fulcrum 224, and since the tongue (not shown) of the mating connector is inserted into the inner end 1251, the rear section 223 of the springing portion behind the middle fulcrum 224 may be interfered by the tongue of the mating connector and cannot be sprung reversely.

2. As shown in fig. 1C, the spring portion front section 222 of the terminal 20 is bent and extends obliquely upward, so that the height of the contact portion 221 of each row of the terminal 20 is not easily controlled to be the same, for example, the height of the spring portion front section 222 between the middle fulcrum 224 and the contact portion 221 is 2mm, if the elevation angle of the spring portion front section 222 is 8 degrees, the protrusion height of the contact portion 221 is 2mm sin (8 degrees) is 0.278mm, if the elevation angle of the spring portion front section 222 is 9 degrees, the protrusion height of the contact portion 221 is 2mm sin (9 degrees) is 0.313mm, and if the elevation angle is 1 degree, the error is 0.313mm-0.278 mm, such error number is quite large.
