Abstract
The utility model discloses a double-line earphone socket, which can be used to solve the problems of the conventional earphone sockets such as weak contact between the shaft sleeves and the grounding wires and inconvenient installation. The double-line earphone socket comprises a pedestal (1), a shaft sleeve (2), an inserting sheet (4), and a spring sheet (5). The shaft sleeve (2) is disposed on one end of the pedestal (1), and a side wall of the other end of the pedestal (1) is provided with a slot (3). The inserting sheet (4) and the spring sheet (5) are oppositely disposed in the slot (3). The shaft sleeve (2) is connected with the grounding wire of the circuit board by a grounding pin in a conductive manner. The double-line earphone socket is characterized in that an outer wall of the pedestal (1) is provided with two symmetrical planes (7), which are provided with elastic clamping pins (6) connected with the shaft sleeve (2); the elastic clamping pins (6) are opened outwardly, connected with the grounding wire of the circuit board in a conductive manner, and ends of the elastic clamping pins are provided with hooks (8). The double-line earphone socket is advantageous in that the electric connection between the shaft sleeve and the grounding wire is reliable, and the installation is convenient.
Description
Technical field
The utility model relates to a kind of electronic component that inputs or outputs for audio signal, is specifically related to a kind of double-circuit earphone socket.
Background technology
Earphone socket is the main electronic component that audio signal inputs or outputs, and earphone socket is installed on the circuit board of electronic equipment.Existing earphone socket mainly is made up of pedestal, axle sleeve, inserted sheet and reed, and pedestal is fixed on the circuit board in the electronic product by installation foot, and axle sleeve is connected ground wire (negative pole) by grounding leg.There is following technological deficiency in this earphone socket: 1. repeatedly plug between plug and the pedestal, easily cause the loose contact between axle sleeve and the ground wire, and break down, must weld or change earphone socket again.2. when installing, pedestal need be fixed on the circuit board by installation foot, installs inconvenient.
The utility model content
In order to overcome the loose contact between existing earphone socket axle sleeve and the ground wire and inconvenient deficiency to be installed, the utility model provides a kind of double-circuit earphone socket, and this double-circuit earphone socket has the characteristics reliable and easy for installation that are electrically connected between axle sleeve and the ground wire.
The technical solution of the utility model is: a kind of double-circuit earphone socket, comprise pedestal, axle sleeve, inserted sheet and reed, axle sleeve is installed in an end of pedestal, the sidewall of the pedestal other end is provided with slot, be provided with relative inserted sheet and reed in the slot, axle sleeve is by the ground conductive on grounding leg and the circuit board, the outer wall of pedestal is provided with the plane of two symmetries, the place is equipped with the elasticity card base that is connected with axle sleeve on two planes, described elasticity card base outwards opens and its end is provided with crotch, the ground conductive on elasticity card base and the circuit board.
Described base outer wall is provided with boss, and boss is corresponding with the end of elasticity card base.
The utlity model has following beneficial effect: owing to take such scheme, predetermined fixed metallic sheath on the circuit board, metallic sheath is electrically connected with the ground wire of circuit board, when assembling, pedestal is inserted in the metallic sheath, blocks mutually and pedestal is clamped by two elasticity card bases and metallic sheath, and is easy for installation; In addition, the conducting of elasticity card base the ground wire on axle sleeve and the circuit board, being connected between elasticity card base and grounding leg conducting simultaneously in parallel axle sleeve and the ground wire, form double-circuit, when grounding leg is loosening when breaking down, signal still can pass through the conducting of elasticity card base, and being electrically connected between axle sleeve and the ground wire is reliable.Certainly, also can make the elasticity card base standby or use as other function, increase the flexibility of using.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, a kind of double-circuit earphone socket, comprise pedestal 1, axle sleeve 2, inserted sheet 4 and reed 5, axle sleeve 2 is installed in an end of pedestal 1, the sidewall of pedestal 1 other end is provided with slot 3, be provided with relative inserted sheet 4 and reed 5 in the slot 3, axle sleeve 2 is by the ground conductive on grounding leg and the circuit board, the outer wall of pedestal 1 is provided with the plane 7 of two symmetries, 7 places are equipped with the elasticity card base 6 that is connected with axle sleeve 2 on two planes, described elasticity card base 6 outwards opens and its end is provided with crotch 8, the ground conductive on elasticity card base 6 and the circuit board.Owing to take such scheme, predetermined fixed metallic sheath on the circuit board, metallic sheath is electrically connected with the ground wire of circuit board, and when assembling, pedestal 1 is inserted in the metallic sheath, blocks mutually and with pedestal 1 clamping by two elasticity card bases 6 and metallic sheath, and is easy for installation; In addition, 6 conductings of elasticity card base the ground wire on axle sleeve 2 and the circuit board, being connected between elasticity card base 6 and grounding leg conducting simultaneously in parallel axle sleeve 2 and the ground wire, form double-circuit, when grounding leg is loosening when breaking down, signal still can pass through 6 conductings of elasticity card base, and being electrically connected between axle sleeve 2 and the ground wire is reliable.Certainly, also can make elasticity card base 6 standby or use as other function, increase the flexibility of using.
Described pedestal 1 outer wall is provided with boss 9, and boss 9 is corresponding with the end of elasticity card base 6.9 position-limiting actions of boss, it is firm that pedestal 1 is installed.
Claims (2)
1. double-circuit earphone socket, comprise pedestal (1), axle sleeve (2), inserted sheet (4) and reed (5), axle sleeve (2) is installed in an end of pedestal (1), the sidewall of pedestal (1) other end is provided with slot (3), be provided with relative inserted sheet (4) and reed (5) in the slot (3), axle sleeve (2) is by the ground conductive on grounding leg and the circuit board, it is characterized in that: the outer wall of pedestal (1) is provided with the plane (7) of two symmetries, locate to be equipped with the elasticity card base (6) that is connected with axle sleeve (2) on two planes (7), described elasticity card base (6) outwards opens and its end is provided with crotch (8), the ground conductive on elasticity card base (6) and the circuit board.
