Abstract
The utility model relates to a plug using on a power converter, comprising conductive pins and conductive plug sleeves, and is characterized in that the conductive pins and the conductive plug sleeves are made into a hollow integrated component. The integrated component can appear in a drum body with thinner bottom and thicker top. Bottom of the drum body is made into the conductive pins while top of the drum body is built into the conductive plug sleeves. The integrated component can also include a straight drum at bottom and a triangular prism body on top. The straight drum is the conductive pins simultaneously the triangular prism body inside can form the conductive plug sleeves. Compared with existing technologies, the utility model adopts pins in hollow structure, and they can be integrated to form with the conductive plug sleeves. Therefore, the plug is characterized in saving materials, lower cost and needing no welding under the condition of meeting requirements of electric connection strength, and its making can be more convenient. Meanwhile reliability in electric connection can be ensured effectively. Thus the improvement can achieve technical effectiveness that cannot be imagined and make the utility model becoming more competitive in more and more oppressive market competition nowadays.
Description
Technical field
The utility model relates to a kind of latch, especially refers to a kind of latch that is used on the power supply changeover device.
Background technology
Because some electrical appliance has and unmatched plug of use occasion or power supply, obviously this uses for different occasions such as house, travelling or office and bring many inconvenience.For this reason, people have just designed various power supply changeover device, it generally includes housing and the plug and socket that is positioned on the housing, wherein plug and socket is realized by latch, promptly this latch is by forming as the conductive pin of plug with as the conduction sleeve of socket, and realize being electrically connected by welding or riveted joint between the two, a kind of latch as shown in Figure 6 comes to this.During use, in the socket on plug (being conductive pin) the insertion body of wall, and the electrical appliance plug inserts on the socket (promptly conduct electricity sleeve) of the power supply changeover device match with it, thereby satisfies the power supply connection request of electrical appliance, therefore brings great convenience to life.But in use find: because the contact pin in the above-mentioned latch adopts solid bar to process, and be processed into one by welding or riveted joint again between itself and the conduction sleeve, therefore such latch has the defective of cost of manufacture height, inconvenience processing, and this welding simultaneously or riveted joint mode have also influenced the electric property of power supply changeover device to a certain extent.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, provides that a kind of material is economized, the cost latch that is used for power supply changeover device low, easy to make.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this latch that is used on the power supply changeover device comprises conductive pin and conduction sleeve, and it is characterized in that: described conductive pin and conduction sleeve constitute the integral piece of hollow form.
As further improvement of the utility model, described integral piece can be the thin down thick cylindrical shell of, and described conductive pin has been formed on the bottom of this cylindrical shell, and top has constituted described conduction sleeve.
Described cylindrical shell oral area outwards one is bent with brace, with convenient location or with the usefulness that is electrically connected of adjacent homopolarity latch.Certainly, also can have and the corresponding projection in cylindrical shell end in the loam cake inwall design of power supply changeover device, when the drain pan of loam cake and power supply changeover device matched, the end of this projection and cylindrical shell offseted and realizes the location of latch.
The upper diameter of described conduction sleeve is good to be slightly less than its underpart diameter, makes the better effects if that contacts between conduction sleeve and the electrical appliance plug, to guarantee electric reliable connection.
As another kind of improvement the of the present utility model, described integral piece comprises the straight tube of bottom and the tri-prismoid on top, and this straight tube is described conductive pin, and tangent plane has then formed described conduction sleeve in the described tri-prismoid.
The stop collar that can also one between described straight tube and the tri-prismoid be shaped on tubulose.
Compared with prior art, because the utility model adopts the contact pin of hollow structure, and itself and the conduction sleeve between another body process, thereby be electrically connected under the condition of intensity satisfying, both material was economized, cost is low, need not welding again, so that processing is got up convenient, can also guarantee simultaneously the reliability that is electrically connected effectively, thereby such improvement can obtain beyond thought technique effect, make the utility model more competitive fierce day by day today in market competition.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment 1: as shown in Figure 1, this latch 1 is that conductive pin 11 is formed on the bottom that this cylindrical shell is thinner by punching press forms down the thin thick cylindrical shell of to copper pipe, and conduction sleeve 12 has been formed at thicker top, has promptly formed the integral piece of hollow form.
Consider latch 1 in transducer the location or with being electrically connected of adjacent homopolarity latch,, the outside one of cylindrical shell oral area is bent with brace 13 here, and design has installing hole 14 on brace.Like this when above-mentioned latch 1 is inserted on the transducer drain pan 2, as shown in Figure 2, utilize installing hole 14 on screw and the above-mentioned cylindrical shell latch 1 to be fixed on the corresponding erection column 21 of drain pan.Simultaneously, also can utilize this installing hole to couple together, so that the attaching plug of a plurality of electrical appliances of on power supply changeover device, pegging graft simultaneously by the conducting strip 3 of lead or sheet metal and adjacent homopolarity latch.In addition, be connected more reliably in order to allow between the conduction sleeve 12 of plug and this power supply changeover device of electrical appliance, in the present embodiment, the upper diameter of leading sleeve 12 is slightly less than its underpart diameter, and makes the more high resilience of two side of conduction sleeve 12.Like this, after the electrical appliance plug inserts conduction sleeve 12, can make the two make contact to one better.
Embodiment 2: as shown in Figure 3, this latch 1 ' be: by copper strips as required after the punching press with the above-mentioned first embodiment difference, one rolls into the straight tube of bottom, the tubulose stop collar 13 at middle part ' and top tri-prismoid again, so straight tube promptly become described conductive pin 11 ', in the tri-prismoid tangent plane then formed conduction sleeve 12 '.During installation, as shown in Figure 4 and Figure 5, when latch 1 ' be inserted on the drain pan 2 of transducer, stop collar 13 ' the be positioned at stopper slot 22 of drain pan, in loam cake 4, also be provided with simultaneously and conduct electricity the fore-set 41 that sleeve 12 ' end offsets, when loam cake 4 and drain pan 2 fixed together, above-mentioned fore-set 41 was tightly with latch 1 ' be positioned on the housing of power supply changeover device.
