Abstract

A short-circuit plug-in structure used in a printed circuit board comprises a short-circuit plug (male) and a short-circuit receptacle (female). The short-circuit plug is prepared by bending a conducting wire (2) and encapsulating with insulating material (1), and a circle of groove that helps to plug out is fabricated on the insulating material; the receptacle is composed of 2 is multiplied by n (n is an integer) jacks made from conducting elastic materials and pins (3) thereof and an encapsulated insulating stand (4); and the geometrical size of the cross section of the conducting wire of the short-circuit plug is corresponding to that of the conducting jacks of the receptacle, which is arranged on a printed circuit board (5), and the jack pins are electrically connected with the corresponding electric wiring by welding. When the short-circuit plug is not plugged in, the jacks in the receptacle are electrically isolated from each other, and when the short-circuit plug is plugged in, the jacks in the receptacle are electrically connected by contacting with a short-circuit plug conductor. The invention remarkably improves the safety and reliability of short-circuit plug-in usage.

Description

A kind of PCB short circuit structure

[technical field]

The present invention relates to electronic component, especially a kind of PCB short circuit structure.

[background technology]

In order to realize different functional requirement selections, the contact pin (public affairs) that selective short circuit is used is housed on PCB usually, insert (mother) with short circuit when needed and be inserted on the corresponding contact pin, corresponding contact pin is electrically connected.There is following defective in such structural shape (be contact pin exposed outside): (1) exposed contact pin is touched by human body easily, and is light then influence the operate as normal of circuit, heavy then generation electric shock even threat to life; (2) Luo Lu contact pin is also touched by other objects in processes such as production, packing, transportation, installation easily, the stressed change that causes relative position size between the contact pin, thereby when the needs short circuit, short circuit insert to insert that difficulty maybe can't be inserted or and contact pin between electric loose contact, influence the operate as normal of circuit.

[summary of the invention]

For solving the defective that the said structure pattern exists, the invention provides a kind of PCB short circuit structure, no matter whether this short circuit structural shape can be in the short circuit state in the short circuit structure, human body all can't touch the current-carrying part of short circuit structure, this short circuit structure can be because of not touched the change that causes short circuit structure division relative size in processes such as production, packing, transportation, installation yet by other objects simultaneously, thereby improved fail safe and reliability that the short circuit structure is used greatly.

The technical solution adopted for the present invention to solve the technical problems is: whole short circuit structure is made up of short-circuit plug (public affairs) and socket (mother); Short-circuit plug is formed with insulating material encapsulation after by the electric wire bending and molding, in the insulating material encapsulation, is shaped on one and encloses the groove of being convenient to pull out; Socket is formed with the jack made of elastomeric material of conduction and the insulating material stand of pin and encapsulation thereof by 2 * n, n=1 wherein, and 2, The cross section geometry of short-circuit plug electric wire is corresponding with the physical dimension of socket conductive jack.Socket is installed on the PCB, and the jack pin is gone up corresponding electric wiring welding formation with PCB and is electrically connected.When short-circuit plug does not insert, electricity isolation mutually between each jack in the socket; After short-circuit plug inserts, in the socket between corresponding jack by forming electrical connection with contacting of short-circuit plug electric wire.

Because the current-carrying part of this socket is encapsulated in the insulating material, short-circuit plug also has the insulating material encapsulation, therefore no matter whether short-circuit plug inserts, and human body all can't touch the current-carrying part of short circuit structure, thereby has guaranteed the safety of life and the normal operation of circuit.Simultaneously the receptacle portion of socket is encapsulated in the insulating material stand, so the relative position of each jack and physical dimension can be because of external force do not change yet in the socket, thereby it is reliable to have guaranteed that short-circuit plug inserts smooth and easy, electric contact.Being shaped on a circle groove in the short-circuit plug insulating material encapsulation, then is to be the rising to pull out and design of short-circuit plug, and it is more convenient that rising of short-circuit plug pulled out.

The present invention and prior art contrast, and effect is positive and tangible.The present invention can effectively avoid the exposed contact pin of existing short circuit structure to be touched by human body easily and influence the circuit operate as normal even the electric shock threat to life takes place; And exposed contact pin is touched by other objects in processes such as production, packing, transportation, installation, cause the change of relative position size between the contact pin, thereby when the needs short circuit, short circuit insert to insert that difficulty maybe can't be inserted or and contact pin between the defective of electric loose contact.

Accompanying drawing 1 is existing short circuit structural representation.

Accompanying drawing 2 is schematic diagrames of existing short circuit structure contact pin distortion after being subjected to external force.

In accompanying drawing 1 and the accompanying drawing 2, contact pin assembly 2 is installed on the PCB3, and when not inserting short circuit connector assembly 1, contact pin is exposed outside.

Accompanying drawing 3 is a kind of PCB of the present invention structural representations with a preferred embodiment of short circuit structure.First is a short-circuit plug when not inserting from left to right in the view, and second is short-circuit plug when inserting, and the 3rd then is the view of short-circuit plug when being inserted into the end.

Accompanying drawing 4 is a kind of PCB of the present invention short circuit detail of construction.

[specifically implementing ten thousand formulas]

As accompanying drawing 3 and accompanying drawing 4, whole short circuit structure is made up of short-circuit plug (public affairs) and socket (mother).Wherein short-circuit plug is formed with the handle of insulating material 1 encapsulation after by electric wire 2 bendings, is shaped on one and encloses groove on the handle of insulating material encapsulation; Socket is formed with the jack made of elastomeric material of conduction and the insulating material stand 4 of pin 3 and encapsulation thereof by 2 * n, n=1 wherein, and 2, The cross section geometry of short-circuit plug electric wire is corresponding with the physical dimension of socket conductive jack.Socket is installed on the PCB5, and the jack pin is electrically connected with corresponding electric wiring welding formation on the PCB 5.When short-circuit plug does not insert, electricity isolation mutually between each jack in the socket; After short-circuit plug inserts, form electrical connection by contacting between corresponding jack in the socket with the electric wire of short-circuit plug.
