Detailed ways

The utility model will be further described below with reference to the drawings and embodiments, but the embodiments in the drawings do not constitute any limitation to the utility model.

Example 1

As shown in Figures 1 to 5, an improved earphone and microphone socket female seat of the present utility model includes a housing 1, a plastic seat 2, a rear cover 3 and a plurality of terminals 4, and the front ends of the terminals 4 are installed on the Inside the plastic seat 2, the rear end of the terminal 4 passes through the back cover 3, the back cover 3 is connected with the plastic seat 2, and the shell 1 is sleeved on the outside of the plastic seat 2, The rear ends of the plurality of terminals 4 are arranged on the same plane. The same plane of the terminals 4 may be a horizontal plane, a vertical plane, or the same plane in any direction, and in this embodiment, it is preferably a horizontal plane. When performing manual welding, the operator only needs to fix the socket female base, revealing one side of the terminal 4, and can easily realize welding of different terminals 4 without flipping the socket female base. The socket base is also suitable for welding by an automatic welding machine. Since the terminals 4 are on the same plane, the welding machine can smoothly realize automatic welding. Therefore, the female socket with terminals 4 on the same plane not only facilitates manual welding, but also realizes automatic welding, greatly improving welding efficiency.

The front end of the plastic seat 2 is provided with a circular hole 5, and the interior of the plastic seat 2 is provided with five slots for installing the terminals 4. The audio shielding switch is provided in the plastic seat 2, and the audio shielding switch The insulating elastic piece 21 is integrally formed with the plastic seat. The audio shielding switch includes an insulating shrapnel 21, a terminal three 43 and a terminal four 44 for transmitting jumper signals, and the terminals three 43 and terminals four 44 are respectively installed on the card on the side of the plastic seat 2 provided with the insulating shrapnel 21. on the slot. The terminal three 43 is provided with an elastic contact piece corresponding to the terminal four 44 for contact and conduction. The terminal 4 also includes a terminal 2 42 and a terminal 5 45 for transmitting audio signals of the left and right channels. The terminal 2 42 and the terminal 5 45 are symmetrically installed on the slots on the other two sides of the plastic base 2 . When the earphone plug is not inserted into the round hole 5, the terminal three 43 and the terminal four 44 are disconnected; when the earphone plug is inserted into the round hole 5, the earphone plug squeezes the insulating shrapnel 21, and the insulating shrapnel 21 makes the elastic contact piece of the terminal three 43 Touch terminal four 44, at this time terminal three 43 is in contact with terminal four 44 and is electrically connected. When the plug is pulled out of the round hole 5, the terminal three 43, the insulating shrapnel 21 and the terminal four 44 return to the initial state under the action of elasticity, and the terminal three 43 and the terminal four 44 are disconnected, thereby realizing the switching of audio shielding.

Preferably, the casing 1 is a metal casing, and the casing 1 is fastened with the plastic seat 2, and the metal casing can prevent audio signals from being disturbed during transmission.

Further, the shell 1 is a metal shell, the shell 1 is socketed with the plastic seat 2, and the shell 1 is conductively connected with a terminal 41 for audio grounding signal transmission, and the terminal 41 is installed on the plastic seat 2. The seat 2 is provided on the slot on the opposite side of the insulating elastic piece 21 . The terminal one 41 is in contact with the metal shell 1, which can prevent the audio signal from being disturbed during transmission and play an anti-interference role.

Example 2

The difference between this embodiment and Embodiment 1 is that the insulating elastic piece 21 is bonded to the terminal three 43. Before assembly, the insulating elastic piece 21 is directly bonded to the terminal three 43 by in-mold injection molding or hot-melt bonding of the terminal. At this time, the insulating elastic piece 21 itself no longer has elasticity, but moves together with the terminal three 43 . The rest of this embodiment is the same as Embodiment 1, and will not be repeated here.
