Abstract
The invention provides a double-grounded small four-core jack, relating to a small four-core jack with two ground terminals. The four-core jack comprises a plastic fixing seat, a middle sleeve, a plug tip and a grounding which are arranged on the plastic fixing seat. The main technical scheme is characterized in that a jack end is provided with double ground terminals; the inclined surfaces of the double ground terminals are provided with contacts; the double ground terminals are designed into a plug type; and the plug tip is designed into a lead-out weld leg. With the double ground terminals provided by the invention, the contacts on the inclined surface are in a extremely reliable contact with the plug ground electrode, when the plug is plugged in, two groups of grounding signals can be given out. The four-core jack has the characteristics of increasing the stability of the equipment performance, eliminating noise of the earphone and the like. Moreover, the profile dimension of the fixing seat can meet the design requirement of miniaturization of customers.
Description
Technical field:
The present invention relates to a kind of small-sized four-core socket, adopt the socket of two ground connection after inserting plug, can provide two winding earth signals, also can make two ground connection and two plug tip structures according to client's needs with two earth terminals.
Background technology:
Existing small-sized four-core socket, earth terminal has only one (like Fig. 1), and earth terminal 1 ' generally be made in the upper horizontal plane of socket can't have been accomplished two earth terminals at narrow and small earth electrode, after inserting plug, can only provide a winding earth signal.
Summary of the invention:
The present invention provides a kind of simple in structure, small-sized four-core socket of two ground connection of eliminating the earphone noise.
The present invention realizes through following technical scheme: a kind of pair of small-sized four-core socket of ground connection comprises the holder of plastics and adorns middle cover, plug tip, ground connection thereon that its major technique characteristic is that said socket end is provided with two earth terminals; The inclined plane of said pair of earth terminal is provided with the contact; Said pair of earth terminal adopts the plug-in type design; A described plug tip is designed to draw leg.
The present invention's two earth terminals adopt the contact on the inclined plane reliably to contact with the plug earth electrode, after inserting plug, can provide two winding earth signals.It is more stable to have the equipment performance of making, and eliminates characteristics such as earphone noise.The holder overall dimension Grain Full foot client designing requirement of miniaturization day by day.
Description of drawings:
Fig. 1 is existing small-sized four-core outlet structure figure;
Fig. 2, Fig. 3 are structural representation of the present invention;
Fig. 4 is the front view of earth terminal;
Fig. 5 is the sketch map of the two plug tip structures of two ground connection.
Embodiment:
Like Fig. 2-shown in Figure 5, the small-sized four-core socket of this pair ground connection comprises the holder 7 and dress middle cover 3, middle cover 4, plug tip 5, the plug tip 6 thereon of plastics, and the socket end is provided with two earth terminals 1,2; The inclined plane of said pair of earth terminal is provided with contact 8; Said pair of earth terminal adopts the plug-in type design; A described plug tip is designed to draw leg.Wherein earth terminal 1,2 adopts plug-in type (DIP) installation and design; A technology plug tip does not have leading foot; According to the designing requirement of client's different circuits; Plug tip can be made and draw leg and become the two plug tip structures of two ground connection; The plane mounts design (SMT)), other 3 reeds adopt the plane to mount design (SMT).The holder overall dimension Grain Full foot client designing requirement of miniaturization day by day that this patent relates to.This small-sized four-core socket has carried out two earth terminal designs, and two earth terminals adopt the contact on the inclined plane reliably to contact with the plug earth electrode, after inserting plug, can provide two winding earth signals.
