Abstract

The utility model discloses a main circuit folded piece connecting and inserting piece and comprises an insulating outer shell, a movable contact head arranged in the insulating outer shell and a conductive plate connecting the movable contact head and an output leading line. The movable contact head is formed by the mutual superposition of a plurality of piece stopping U-shaped metal pieces. A column crank shaft being vertical to the conductive plate is arranged on the conductive plate, and every stopped two halves of the U-shaped metal pieces hold the column crank shaft to be clamped tightly by a clamping spring. The connecting and inserting piece has the advantages of good electrical conductivity, big heat radiation area and small temperature rising amplitude.

Description

Main circuit laminated connector

The utility model relates to a kind of circuit connector.

Big electric current commonly used in the prior art exchanges connector as shown in Figure 1, curving U-shaped by the sheet metal of two broads fixedly forms, in use, plug contacts with contact formation line in theory, electric conductivity is good, but when reality is used, because by dress, many-sided factors such as debugging, tend to be subjected to the influence of external force to produce site error between plug and the contact, make plug contact and become a contact with line between the contact, thereby influenced the electric conductivity and the heat dispersion of connector, also can cause burning of contact and shell to damage when situation is serious, brought unsafe factor to the user.

The purpose of this utility model is: provide a kind of electric conductivity and heat dispersion main circuit good, safe in utilization stacked connector.

The technical solution of the utility model is: the stacked connector of a kind of main circuit, comprise insulation crust, be installed in movable contact in the insulation crust, connect the conductive plate of movable contact and output lead, and the U-shaped sheet metal stack that disconnect relatively independent by some groups of described movable contact formed, described conductive plate is provided with vertical with it cylindricality and turns axle, every group of U-shaped sheet metal that disconnects closes up to be embraced cylindricality and turns axle, fixing by the jump ring chucking then.

The utility model has the advantages that:

1. because the axle that turns on the conductive plate of the present utility model is processed to cylindrical shape, make the conductive section between contact and the conductive plate become very big, during work the contact of connector with turn the axle be connected and can rotate around the cylinder center all the time, and regulate the contact center distance automatically, make electric conductivity fine, temperature rise is very little.

2. because contact of the present utility model is made up of some groups of U-shaped sheet metal stacks, when increasing, needs only the quantity that increases lamination, thereby solved the difficult problem that present card connector spare does not have the above big specification of 400A, filled up domestic blank by electric current.

3. because contact of the present utility model is made up of the stack of some groups of U-shaped sheet metals, plug forms several short-terms with contact and contacts during use, even try have error, each short-term also can both contact well by debuging, thereby has improved the electric conductivity of connector.

4. because contact of the present utility model is made up of some groups of U-shaped sheet metal stacks, has disperseed contact-making surface, thereby reduced plug power.

5. because contact of the present utility model is made up of some groups of U-shaped sheet metal stacks, the area of dissipation of contact has been increased greatly, thereby improved the heat dispersion of connector.

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1 is the front view of connector in the prior art;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is a front view of the present utility model;

Fig. 4 is the left view of Fig. 3.

Wherein: 1. contact; 2. conductive plate; 3.U shape sheet metal; 4. cylindricality turns axle; 5. jump ring; 6. punching hole.

Embodiment: as can be known by Fig. 1, Fig. 2, Fig. 3, Fig. 4, the stacked connector of a kind of main circuit, comprise insulation crust, be installed in movable contact 1 in the insulation crust, connect the conductive plate 2 of movable contact 1 and output lead, and U-shaped sheet metal 3 stacks that disconnect relatively independent by some groups of described movable contact 1 are formed, the vertical with it cylindricality that is provided with described conductive plate 2 turns axle 4, every group of U-shaped sheet metal 3 that disconnects closes up to be embraced cylindricality and turns axle 4, fixing by jump ring 5 chuckings then.Described every U-shaped sheet metal 3 is provided with punching hole 6, is fixed with jump ring 5 on the punching hole 6 on two corresponding U-shaped sheet metals 3.Because the cylindricality on the conductive plate 2 of the present utility model turns axle 4 and is processed to cylindrical shape, make the conductive section between movable contact 1 and the conductive plate 2 become very big, during work the contact 1 of connector with turn axle and 4 be connected and can rotate around the cylinder center all the time, and regulate contact 1 centre-to-centre spacing automatically, make electric conductivity fine, temperature rise is very little.Because movable contact 1 of the present utility model is made up of some groups of U-shaped sheet metal 3 mutual superposition, when increasing,, there is not the above difficult problem of specification greatly of 400A thereby solved present card connector spare as long as increase the quantity of lamination by electric current, filled up domestic blank.Plug contacts with movable contact 1 several short-terms of formation during use, even have error, each short-term also all to contact well by debuging examination, thereby has improved the electric conductivity of connector.Disperse contact-making surface, thereby reduced plug power.The area of dissipation of movable contact 1 has been increased greatly, thereby improved the heat dispersion of connector.
