The upper end of the conducting bar is connection end; the low end is the contact end. The connection ends of the neighboring conduction bars are interconnected, the connection ends of the interconnected bars are covered with insulation layer; the contact end of the conducting bar consists of two elastic pieces of symmetry, angle difference by bending at front and diamond sections. The insulation layer and conducting bar are jointed via the thermoplastic molding, the insulation layer thermoplastic section has location hole, and the two sides of the pressed section have grains. The joint and pressing sections of the connection ends of the neighboring conducting bars have break lines for cutting. The number of the conducting bar may be two to ten, the joint piece is convenient, the elastic needle plug provides large pressure, the pressure value is stable, the utility model can realize high degree air sealing connection, the contact resistance is small and temperature variation is less, thereby realizing ideal power level allocation for the electrical system.

Description

Plug-in connection piece

Technical field

The utility model relates to a kind of current potential of electric field middle connecting terminal Volleyball Association when connecing that be applied in and distributes connector, and being used for centre-to-centre spacing specifically is the connector that connects between 6.2mm terminal board center terminal.

Background technology

The connector of prior art is to adopt fixed center connector, this connector is by plate, in establish the connecting tube of screw thread and screw three parts are formed, its processed complex, and expend copper product, when operating, must fix whole connector with screw attachment, not only loaded down with trivial details but also time-consuming, and contact pressure is wayward, makes the sliding tooth of screw screw thread when screwing force is big easily, screwing force is little then cause easily loosening, cause contact pressure little, make contact resistance become big, cause temperature rise, so must be by personnel operation with certain technical merit, when the dismounting connector, must all become flexible screw in addition, quite time-consuming.

The utility model content

Technical problem to be solved in the utility model is to overcome existing connector above shortcomings, a kind of conducting strip square hole and rubber-like needle-like plug that can insert fast in the terminal is provided, stable performance, easy to operate connector, its technical problem to be solved can be implemented by the following technical programs.

Plug-in connection piece is made up of apart from the busbar that is 6.2mm a group switching centre, and the upper end of busbar is a link, and the lower end is a contact jaw, and the link of adjacent each busbar is coupled to each other,

The busbar link that is coupled to each other is surrounded by insulating barrier outward;

The resilient connection sheet of the contact jaw of busbar is symmetrical by two profiles, the front end bending fits in declinate and the section combination assumes diamond in shape shape constitutes.

Described insulating barrier and busbar link thermoplastic shaping, the thermoplastic pressing portion of insulating barrier is provided with location hole, and the both sides of pressing portion are provided with striped.

Connecting the junction of adjacent conductive row link and corresponding pressing portion is provided with and conveniently cuts off the broken line that cuts.

Described two resilient connection sheets can be 27.36 degree near the angle of link, are 2.3mm at a distance of two ends, farthest distance between two resilient connection sheets.

The number of described busbar can be 2～10; Further, the most suitable number of described busbar is 10.

Adopt the connector of this technical scheme, easy to use, materials are saved, and flexible needle-like plug contact pressure is big, and force value is stable, can realize highly airtight connection, and contact resistance is little, and temperature rise is low, and the current potential that can realize ideal in electrical system distributes.

Among the figure: 1, busbar 2, insulating barrier 21, location hole 22, striped 31, conducting strip 32, conducting strip 41, plate 42, connecting tube 43, screw

Embodiment

Be illustrated in figure 1 as the connector of prior art, adopt fixed center connector, this connector by plate 41, in establish screw thread connecting tube 42 and screw 43 3 parts form.Must be connected and fixed with screw 43 during operation, the screwing force size is wayward, must must all become flexible screw 43 when the dismounting connector by the personnel operation with certain technical merit, and is quite time-consuming.

As Fig. 2 to Figure 4 shows that quick plug-in connection piece described in the utility model, form apart from the busbar 1 (totally 10 pairs) and insulating barrier 2 thermoplastics that are 6.2mm by a group switching centre, the upper end of busbar 1 is a link, the lower end is a contact jaw, the link of adjacent each busbar 1 is coupled to each other, the link that is coupled to each other is insulated the encapsulation of layer 2 thermoplastic, it is symmetrical by two profiles to be in the outer busbar 1 contact jaw structure of insulator seal encapsulation, front end bending fits in the assume diamond in shape resilient connection sheet of shape of declinate and section combination and constitutes, form two angles (near link one side) and be 27.36 ° needle-like spring contact, two spring contact projection bending part far-end spacings are 2.3mm, the plate material forms by the high-quality tin bronze is zinc-plated, and insulating barrier 2 is formed by high-quality fire-retardant nylon material thermoplastic.

The thermoplastic pressing portion of insulating barrier 2 is provided with the location hole 21 of two Shooting Technique location, the both sides of pressing portion are provided with many stripe 22, connecting adjacent conductive arranges the junction of 1 link and corresponding pressing portion and is provided with and conveniently cuts off the broken line that cuts, can cut into 2～9 connector as required, the place of cutting can add protecting cover simultaneously, to guarantee insulation.
