Abstract
A small double-grounding four-core socket relates to the small four-core socket which is provided with two grounding terminals. The small double-grounding four-core socket comprises a plastic fixed base, a middle sleeve, a tip and grounding, wherein the middle sleeve, the tip and the grounding piece are installed on the fixed base. The small double-grounding four-core socket is characterized in that the two grounding terminals are arranged at the socket end. Contacts are arranged on the inclined surfaces of the two grounding terminals which adopt a plug-in design. The tip is designed into a lead welding pin. The two grounding terminals adopt extremely reliable contact of the contacts on the inclined surfaces and socket grounding, and two groups of grounding signals can be sent out after a plug is inserted. The small double-grounding four-core socket has the advantages of enabling equipment performance to be more stable, eliminating noise of a headset and the like. The overall dimension of the fixed base is small, thereby meeting design requirements of customers for increasing miniaturization.
Description
Technical field:
The utility model relates to a kind of small-sized four-core socket with two earth terminals, adopts 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.
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 utility model provides a kind of simple in structure, small-sized four-core socket of two ground connection of eliminating the earphone noise.
The utility model is realized 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 above 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 utility model 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 the structural representation of the utility model;
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 above that 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; Can plug tip be made and draw leg and become the two plug tip structures of two ground connection, the plane mounts design (SMT)), other 3 reeds employing planes 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.
