Description

Attaching plug

The utility model relates to a kind of attaching plug, particularly relates to a kind of single-phase the two poles of the earth attaching plug, belongs to single phase poaer supply plug technical field.

Current China single-phase the two poles of the earth attaching plug, its electric-conductor are sheet or columned parallel electrically conductive spare, when it inserts in the single phase poaer supply Die for Reeds of Connector Jack, rely on reed clamping plug conducting spare with energized.Reed in the socket all adopts the phosphor bronze leather to do and since at work because of electric current by producing certain heat, make reed produce thermal fatigue; Again because of when work electric-conductor insertion and extract, reed produces mechanical fatigue again.The influence of reed heat fatigue and mechanical fatigue, its chucking power weakens gradually, progressively increases for the gap of inserting electric-conductor, thereby make reed and contacting of plug conducting spare become inelastic contact or do not contact (being usually said loose contact), plug was easily deviate from from socket and was caused the outage of power consumption equipment this moment, brought the many inconveniences of storage to the user.

The purpose of this utility model is to provide a kind of attaching plug, uses this plug, both need not change the structure of existing socket with matching, can make both remain good electrical contact again, thereby use power consumption equipment to bring great convenience to the user.

The purpose of this utility model is achieved through the following technical solutions:

The attaching plug that the utility model provides, it comprises base (1), loam cake (10), be located between base (1) and loam cake (10) and two conducting strips (9) that are parallel to each other, the end that conducting strip (9) is located in the plug base (1) is equipped with terminal screw (5), it is characterized in that: be positioned between two conducting strips (9) on the base plate (8) in base (1) and be provided with a runner assembly, runner assembly comprises moving block (7) and the vertical rotation axis (14) that is fixed on its bottom surface, pass and be connected to turn-knob (15) in the through hole (13) that rotation axis (14) is opened in its termination on base plate (8), two opposite flanks of moving block (7) are the plane, two opposite flanks are concave surface in addition, it between adjacent two sides arc surface, clamp a back-moving spring (4) on two terminal screws (5) respectively, biside plate (2) elasticity in the other end of two back-moving springs (4) and the base (1) is joined.

Because the utility model only is runner assembly of the middle increase of two conducting strips (9) in the attaching plug of original single-phase the two poles of the earth, the external form of two conducting strips (9) in the utility model and fitted position are all identical with original plug like this, therefore the socket that matches with the utility model also need not be changed, in other words, under the situation that does not change existing socket, also can use the utility model fully, therefore highly versatile of the present utility model.

Owing to be provided with runner assembly in the utility model, runner assembly comprises moving block (7) and the vertical rotation axis (14) that is fixed on its bottom surface, pass and be connected to turn-knob (15) in the through hole (13) that rotation axis (14) is opened in its termination on the base plate (8) of base (1), two opposite flanks of moving block (7) are the plane, two opposite flanks are concave surface in addition, it between adjacent two sides arc surface, in addition, on two terminal screws (5), clamp a back-moving spring (4) respectively, biside plate (2) elasticity in the other end of two back-moving springs (4) and the base (1) is joined, therefore work as plug and loose contact in socket, occurs, when plug easily comes off from socket, rotatable turn-knob (15) also rotates to drive moving block (7), and utilizing any a pair of arc surface that is on the moving block (7) on its diagonal to promote the end that two conducting strips (9) are positioned at plug moves laterally, and make back-moving spring (4) shrink, meanwhile, the state that the other end of two conducting strips (9) promptly tilts to the inside with the parastate and becoming of the contacted end of Die for Reeds of Connector Jack will be by its operate as normal the time, to two reeds in the socket firmly be vised like this, not only conducting strip (9) takes a turn for the better immediately with the situation that contacts of Die for Reeds of Connector Jack and forms good electrical contact at this moment, and, make plug also can not split away off from socket because the distance between plug two conducting strips (9) diminishes.When needs with plug when socket is extracted, counter-rotation turn-knob (15), arc surface on the moving block (7) is not contacted with conducting strip (9), and the plane on the moving block (7) is contacted with conducting strip (9), end with contacted two conducting strips of Die for Reeds of Connector Jack (9) will become parastate again like this, and just can pull out plug at an easy rate this moment from socket.
