Description

Data line plug

Technical Field

The invention relates to the technical field of data lines, in particular to a data line plug.

Background

Lightning plug is the plug of apple data line. The power pin of the Lightning plug is the first pin located at the edge of the PCB inside the plug. The outer edge of the Lightning plug connector is encapsulated by a metal material, and an insulating material is filled between the contact and the metal encapsulation shell to ensure the electrical isolation between the power line contact and the metal encapsulation shell. However, for the connecting wire of the Lightning plug connector, the power line of the Lightning plug must be soldered to the PCB inside the Lightning plug at the position closest to the metal package housing, so the soldering true position error of the power line and the PCB must be smaller than 0.3mm, otherwise there is a risk of short circuit between the power line and the PCB at the joint.

Generally, in order to charge the battery of the electronic device in a relatively short time, only two measures, namely increasing the voltage or increasing the current, are taken. In which increasing the voltage may lead to a reduction in the life of the battery, it is more common to increase the charging efficiency of the battery by increasing the current. However, increasing the current tends to be accompanied by an increase in the outer diameter of the power cord, which may result in a relatively short time during which a relatively large amount of current can flow. Since the welding space of the lighting plug is limited, if the outer diameter of the power line is increased, the requirement of increasing the welding alignment is necessarily accompanied, and whether the risk of short circuit between the power line and the metal housing may occur is mean that the fraction defective of the product is increased.

Therefore, a data line plug is needed to solve the above technical problems.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 3, the present embodiment discloses a data line plug 1, which comprises a plug 1 which is surrounded by an alloy material , a PCB2 connected to the plug 1, a connection wire 3 connected to the PCB2, and a metal shell 4. Preferably, the metal case 4 is made of copper or a normally malleable or foldable alloy such as stainless steel , but may be made of other metals. The PCB2, the end that the plug 1 and the PCB2 link to each other and the one end that the connecting wire 3 links to each other with the PCB2 all cladding in metal casing 4, and the other end of connecting wire 3 links to each other with the USB interface. The connection line 3 includes a power line 31, and the power line 31 is located at an edge of the PCB 2. An opening 411 is formed in the metal shell 4, the opening 411 is located at a position where the power line 31 is connected with the PCB2, and the insulating block 5 is sealed on the opening 411.

An opening 411 is formed in the metal case 4, the joint of the power cord 31 and the PCB2 cannot approach or touch the metal case 4, thereby preventing the power cord 31 and the metal case 4 from being short-circuited, and the insulating block 5 can seal the power cord 31 having completed the welding process with the PCB2, thereby further reducing the risk of short-circuiting between the power cord 31 and the metal case 4 due to other factors. The insulating block 5 may be formed by injecting plastic into any one of the opened metallic shells 4, and includes an opening 411 for sealing the welding of the power cord 31 on the PCB 2.

Preferably, in the present embodiment, an insulating medium is filled between the metal shell 4 and the PCB2, and the insulating medium can improve the insulation between each strand of adjacent wires and between each strand of wires and the metal shell 4 in the connection line 3, and can also enhance the connection strength between the wires and the PCB2 and the structural strength of the wires themselves.

As shown in fig. 1, a protective sleeve 6 is disposed at an end of the metal shell 4 away from the plug 1, and an end of the connection wire 3 close to the PCB2 is covered in the protective sleeve 6. The protection cover 6 is covered on the connection wire 3 outside the metal shell 4, so as to fix the position of the connection wire 3 and the PCB2 with respect to each other and the connection strength, and simultaneously, the end of the metal shell 4 away from the plug 1 can be sealed, so as to protect the connection wire and the metal shell. The protective sleeve 6 is made of insulating material.

As shown in fig. 1, 2, 4 and 5, the metal shell 4 includes a first shell 41 and a second shell 42, and the first shell 41 and the second shell 42 are spliced to form the metal shell 4. The first housing 41 and the second housing 42 are both provided with openings 411, and the openings 411 on the second housing 42 and the openings 411 on the first housing 41 are symmetrically arranged relative to the center line of the data line plug. When the metal shell 4 is assembled on the outer side of the PCB2, since the openings 411 are opened on the first shell 41 and the second shell 42, the positions of the first shell 41 and the second shell 42 can be interchanged, i.e., the first shell 41 and the second shell 42 can be formed by using the same set of mold as the component . If only the first housing 41 or the second housing 42 has the opening 411, the opening 411 needs to be aligned with the power cord 31, and at this time, the first housing 41 and the second housing 42 are formed by different molds, so that the first housing 41 and the second housing 42 cannot be interchanged. If the positions of the first casing 41 and the second casing 42 are not interchangeable, the mounting efficiency of the metal casing 4 is low, and there is a high possibility that the opening 411 does not correspond to the power supply line 31 due to carelessness, resulting in the pivot processing plant .

As shown in fig. 2, the end of the metal shell 4 away from the plug 1 is provided with a clip matching with the connecting wire 3, and the clip is formed by a first clip part 412 arranged on the first housing 41 and a second clip part 422 arranged on the second housing 42. The hoop may be further coated internally within the protective cover 6 to reduce displacement of the hoop or the pathogenic FENG from the hoop through the protective cover 6 the hoop. The first clamp portion 412 is an arc-shaped plate matched with the connecting wire 3, and the second clamp portion 422 comprises an arc-shaped plate matched with the connecting wire 3 and fixing wings connected to two ends of the arc-shaped plate. When the first housing 41 and the second housing 42 are assembled to the outside of the PCB2, the first clip portion 412 and the second clip portion 422 both cover the connection line 3, and the two fixing wings of the second clip portion 422 are bent inward to be fixed to the outside of the first clip portion 412. If the first housing 41 and the second housing 42 are formed using the same mold, the same shape of the first yoke portion 412 and the second yoke portion 422 may be sequentially formed into a letter-clamp using the umbilical member 3.

The insulating block 5, the insulating medium and the protective sleeve 6 are all made of plastic. After the metal shell 4 is assembled, the data line plug 1 is placed into an injection mold, plastic is injected into a mold cavity, and the insulating block 5, the filling medium and the protective sleeve 6 are integrally formed in an injection molding mode. Three integrated into one piece can be with plug 1 and metal casing 4 fixed connection, can also improve the intensity of each strand of wire.
