Embodiment

Specific embodiment of the utility model as illustrated in figs. 1-16, a kind of Portable conversion socket, including jack body 1, Power line 2, plug 3, changeover plug 4 and jack 11, in the jack body 1 on be provided with conducting strip component 12, jack body 1 The installation cavity 13 installed for conducting strip component 12 is inside provided with, the plug 3 includes housing 31, the first insert-connecting plate 32 and second is inserted Contact pin 33, the insert-connecting plate 33 of the first insert-connecting plate 32 and second forms to rotate with housing 31 to be set, and is also set in the jack body 1 It is equipped with the overload protection component 5 electrically connected with conducting strip component 12.Overload protection component 5 is fixed on installation cavity 13 by support 51 Interior, overload protection component 5 includes bimetal leaf 52, and one end of bimetal leaf 52 is connected on support 51, on the end of the other end The first contact 53 is provided with, the side of the first contact 53 is provided with the second contact 54, the contact 54 of the first contact 53 and second Between be provided with baffle plate 55, one end of baffle plate 55, which stretches out, to be passed jack body 1 and forms SR 551, is set on baffle plate 55 It is equipped with the strip through-hole 552 for passing through and turning on for the first contact 53 and the second contact 54, baffle plate 55 is located at the first contact 53 and the The end of the lower section of two contact 54 is barrier end 553, and the position of the first contact 53 and the top of the second contact 54 is located on the baffle plate 55 The place of putting is provided with spring 56, and the both ends of spring 56 are connected into the first spring base 561 and second spring seat setting up and down respectively On 562, the first spring base 562 is the upper end inwall of strip through-hole 552, and one end of second spring seat 562 is fixed on support 51 On, the other end extends out to ammunition feed spring 56 in strip through-hole 552 and abutted so that and spring 56 is arranged in strip through-hole 552, and Positioned at the first contact 53 and the top of the second contact 54, when the first contact 53 and the disconnection of the second contact 54, baffle plate 55 is in spring Motion makes the barrier end 553 of baffle plate 55 be placed between the first contact 53 and the second contact 54 upwards in the presence of 56.Overload protection The setting of component 5 is to prevent socket or electrical equipment to be burned out, because when the electrical equipment connected on socket is more, work(easily occurs Rate is excessive, more than the peak load of circuit, potential safety hazard be present, personal safety is threatened, and overload protection component 5 is by double gold Category piece 52 is formed, and bimetal leaf 52 is also referred to as thrermostatic bimetal-plate, because the thermal coefficient of expansion of each constituent element layer is different, works as temperature change When, the deformation of active layers is greater than the deformation of passive layer, so as to bimetal leaf entirety will to passive layer curving, then this The curvature of kind composite is changed so as to produce deformation, and bimetal leaf 52 is connected on the circuit of conducting strip component 12, the When one contact 53 and the second contact 54 contradict conducting, the circuit of conducting strip component 12 is connected, the first contact 53 and the second contact 54 During disconnection, the circuit of conducting strip component 12 also disconnects, and plays a protective role, and when the electrical equipment change being connected on socket is more, flows through The electric current of bimetal leaf 52 becomes big, temperature rise, and when reaching certain temperature, the deformation of bimetal leaf 52 makes the first contact 53 and second Contact 54 disconnects, i.e., whole circuit disconnects, and at this moment baffle plate 55 moves in the presence of spring 56, though barrier end 553 move to First contact 53 and the position of the second contact 54 alignment, between the first contact 53 and the second contact 54, play cut-off, when After the temperature cooling of bimetal leaf 52, the recovery of shape of bimetal leaf 52, the original contact 54 of first contact 53 and second can weigh It is new to abut conducting, but because a group cut-off 553 is placed between the first contact 53 and the second contact 54, the first contact 53 and the second contact 54 can not directly turn on, and need to be pressed down on baffle plate 55 by SR 551, barrier end 553 is deviateed the He of the first contact 53 Second contact 54, i.e., passed through positioned at the first contact 53 and the lower section of the second contact 54, such contact 54 of first contact 53 and second Strip through-hole 552 abut conducting, improve security, ensure the electrical equipment on socket is all pulled out or pulled out part connect again it is slotting Seat, structure is safe and reliable, and overload protection component 5 can also be realized by miscellaneous part, such as fuse or resistance wire.

Loophole 14 is provided with the outer peripheral face of above-mentioned jack body 1, is provided with loophole 14 and overload protection component 5 The overload light 141 of electrical connection, loophole 14 electrically connect into smiling face's type, overload light 141 with bimetal leaf 52.Overload refers to Show that lamp 141 is used for showing the carrying degree of socket, raised with the temperature of bimetal leaf 52, the light of overload light 141 shows Show slowly lighted from a lateral opposite side with the shape of loophole 14, temperature is higher, the area that overload light 141 lights Bigger, user according to the display situation of overload light 141, can judge the bearing capacity of socket, exclude overload in advance, avoid Start bimetal leaf 52, overload light 141 is made up of several bulbs, and the bulb number that temperature difference is lit is different, more Securely and reliably, potential safety hazard is excluded.

Be respectively arranged with above and below above-mentioned baffle plate 55 with baffle plate 55 form spacing cooperation the first limited block 511 and Second limited block 512.First limited block 511 and the second limited block 512 are each attached on support 51, the first limited block 511 and The setting of two limited blocks 512 defines the shift motion of baffle plate 55, baffle plate 55 is not fallen out jack body 1 or is excessively stretched into slotting Seat body 1, Stability Analysis of Structures, increases the service life, baffle plate 55, can be spacing with the first limited block 511 or the second in moving process Block 512, which is formed, to be contradicted spacing, and the first limited block 511 and the second limited block 512 correspond to the upper end of baffle plate 55 into setting up and down respectively And lower end.
