Description

Electrical plug

The present invention relates to an electrical plug, and more particularly to an electrical plug in which an electrical tab is engaged with an assembly slot.

The conventional Ethernet power supply integrates the data signal with the power signal, so that the electrical plug and the socket wire simultaneously transmit data and power, thereby saving the cost and time required for installing the power supply. When assembling the transmission wire to the electrical plug, the assembler needs to use a tool to press the electrical tab of the electrical plug into the assembly slot of the plastic housing of the electrical plug, and pierce the insulating skin of the transmission wire through the electrical tab. The electrical tab is electrically connected to the transmission line. In general, in order to avoid the difficulty that the gap between the electrical tab and the wall surface forming the assembly groove is too small, and the electrical tab is pressed into the assembly groove of the plastic housing, the width of the electrical tab is mostly intentionally narrowed. The gap between the large electrical tab and the wall surface forming the assembly groove can be fixed only after the electrical tab is pressed into the assembly groove of the plastic housing.

However, when the electrical plug is powered, the temperature of the electrical tab will increase, and the high-temperature electrical tab will easily melt the portion of the plastic housing that is fixed to the electrical tab, thereby causing assembly of the plastic housing and the electrical tab. The strength is reduced. Once the assembly strength of the plastic case and the electrical tab is reduced, the electrical tab is easily blocked by the butt wire of the socket and is shaken relative to the plastic case. In detail, when the user subsequently inserts the electrical plug into the socket in the insertion direction, since the initial contact point of the electrical tab and the butt wire are likely to generate sparks and then melt, the initial contact of the electrical tab after the spark is extinguished The dots are glued to the butt wires, resulting in a solder-like phenomenon. As the user continues to insert the electrical plug into the socket, since the initial contact point of the electrical tab is adhered to the mating lead, the electrical tab is pulled by the reaction force from the mating lead and the electrical tab is placed in the assembly slot. mobile. The gap between the electrical tab and the wall surface forming the assembly slot has been increased due to the high temperature. When the electrical tab is pulled, it is easier to loosen the assembly slot of the plastic housing, resulting in poor contact between the electrical tab and the transmission lead. And the effect of data transmission and power supply of the transmission line is deteriorated.

The present invention provides an electrical plug for improving the problem that the electrical connector is loosened after the electrical plug is inserted into the socket.

The electrical plug disclosed in one embodiment of the present invention is adapted to be inserted into a socket in an insertion direction, and the socket has a plurality of butt wires. The electrical plug includes a housing and a plurality of electrical tabs. The housing has a receiving space and a plurality of assembly slots, and the assembly slots respectively communicate with the receiving space. Each of the electrical tabs comprises a base portion, a neck portion and a pair of joint portions. The base portion and the pair of joint portions are respectively connected to the two sides of the neck portion, and the neck portion is respectively located in the assembly groove of the outer casing, and the joint portion is respectively connected to the joint portion. The butt wire of the socket. Wherein in the insertion direction, the width of the neck is 85% or more and 96% or less of the width of the assembly groove.

According to the electrical plug disclosed in the above embodiment, by increasing the width of the neck of the electrical tab in the insertion direction, the gap between the neck of the electrical tab and the wall surface of the housing forming the assembly groove can be reduced. When the electrical plug is plugged or unplugged, the electrical tab is formed to limit the moving position of the wall of the assembly slot, and the electrical tab is maintained at the mounting position when the original connector is pressed into the housing, thereby improving the data between the electrical plug and the socket. Transmission and power supply effects.

The upper portion 130 and the lower portion 140 surround the accommodating space S for accommodating a plurality of transmission wires 30. The assembly slot 150 is located at the lower portion 140, and each of the assembly slots 150 communicates with the accommodating space S. The slot 160 is located at the front portion 110.

Each of the electrical tabs 200 includes a base portion 210, a neck portion 220, and a pair of joint portions 230. In the insertion direction D, the width of the base portion 210 is 2.65 mm or more and 2.71 mm or less, the width of the neck portion 220 is 2.09 mm or more and 2.19 mm or less, and the width of the joint portion 230 is 3.45 mm or more and 3.55 mm or less. The width of 220 is 74% or more and 85.5% or less of the width of the base portion 210, and the width of the neck portion 220 is 56.5% or more and 66.5% or less of the width of the joint portion 230. However, the width dimension of the base 210, the width dimension of the neck 220, and the width dimension of the joint portion 230 are not intended to limit the present invention.

The base portion 210 and the pair of joint portions 230 are respectively connected to both sides of the neck portion 220. The base portion 210 passes through the assembly groove 150 of the outer casing 100 in a pressing direction P for respectively corresponding to the transmission wire 30, and pierces the insulating skin of the transmission wire 30 to electrically connect the base portion 210 and the transmission wire 30, and the neck portion.
