Abstract

The invention relates to a connector (1) having clamping contacts (2) mounted on a pair of bus bars (3a, 3b), wherein each of the clamping contacts (2) has two contact springs (4a, 4b) which are arranged one next to the other and have the same orientation, which are connected to one another by a common bus bar, characterized in that the bus bars (3a, 3b) having the contact springs (4a, 4b) lying opposite one another are connected to one another in one piece by a single component.

Description

The connector that on a pair of bus terminal rows, has clamping contacts

Technical field

Invention relates to a kind of connector that has clamping contacts on a pair of bus terminal rows, wherein each of clamping contacts has two contact springs that compress mutually, contact spring place one by one and have identical towards, they are connected to each other by a public bus terminal rows.

Background technology

This connector apparatus is by for example DE 26 39 642A1 are known.In the document, two bus terminal rows are connected by integral body so that become conductor and be anchored in the casket body, and the bus terminal rows of telling binding post has contact spring.Owing to the connection of bus terminal rows must be arranged, and can not make the straight contact spring of delegation, so the manufacturing cost of this equipment is very expensive with out of phase or signal.In addition, bus terminal rows be arranged in the very big position of requirement in the base, thereby can not obtain the compact Layout of multirow contact spring.

Summary of the invention

The objective of the invention is to improve the connector of type described above, so that can obtain a compact Layout with different a plurality of bus terminal rows that are equipped with, it has a lower manufacturing cost.

According to invention, this problem is to solve by a connector that clamping contacts is installed on a pair of bus terminal rows, each of clamping contacts has two contact springs that compress mutually therein, contact spring side by side arrange and have same towards, by a common bus terminal rows, they are linked to be an integral body, and the bus terminal rows of contact spring respect to one another connects into a global facility therein.

According to a best way of realization of the present invention, the bus terminal rows of contact spring respect to one another connects into integral body by fishplate bar, this fishplate bar is folded so that bus terminal rows is placed Face to face, and the end of contact spring is connected by friction under prestress.

According to another best way of realization, on the diverse location of bus terminal rows axial length direction, have contact spring, a plurality of connect into whole bus terminal rows to by self fold, and isolate, so that their contact spring becomes straight line each other by insulating trip.

According to another way of realization, the bus terminal rows of arranging stratification up and down is to side by side being folded into one group, and the intermediate insulation sheet provides more weak bonding friction.

According to another way of realization, different binding posts is placed in outside bus terminal rows to shorter, and is placed in inner bus terminal rows to long have different length in group.

According to another best way of realization, a contact pawl is connected so that each bus terminal rows of conducting is right.

In addition, according to a way of realization, an additional bus terminal rows is on the limit that is disposed at least one group of bus terminal rows, so that all contact springs are disposed on the same level, and at least two row.

Description of drawings

Invention will be in the back by with reference to accompanying drawing to the description of embodiment and by more detailed explanation.In the drawings:

Fig. 1 shows a way of realization according to the connector of invention, perspective;

Fig. 2 shows another partial view of perspective of the connector of Fig. 1;

Fig. 3 shows another partial view of Fig. 2 connector perspective.

Embodiment

We see a connector 1 that has clamping contacts 2 on Fig. 1, its each have two

contact spring

4a, 4b, its end contacts in the mode of friction under prestressing force.To 3a, 3b is last to be realized and arranges with single parts contact spring 2, and they have the layout dividually of same distance abreast at a bus terminal rows.Double bus line bank 3a, 3b are that the fishplate bar of being realized 5 of single part is connected to integral body by one equally.From the point of view of manufacturing technology, this layout has very big advantage, and we can be with an operation by making bus terminal rows 3a from plate stamping, 3b, and fishplate bar 5 and

contact spring

4a and 4b, and we can give contact spring its last shape.Next double bus line bank 3a, 3b 180 ° form its final form around a bending rib in the bending of fishplate bar 5 places by the sheet material semi-finished product.At last, be used for being mounted for the right end of electrically conducting bus terminal rows to the contact pawl 7 of bus terminal rows power supply.According to another embodiment, contact pawl 7 can directly cut out on bus terminal rows.

Fig. 2 and 3 shows a right integral body of bus terminal rows, and it comes manufactured according to aforementioned connector principle fully.Among the embodiment shown on Fig. 2 and Fig. 3, three couples of bus terminal rows 13a are arranged, 13b; 14a, 14b; And 15a, 15b, they one on another and before the bending program, separated whole then the bending by the insulation fishplate bar.The insulation fishplate bar has more weak viscosity but is not bonded, to avoid its extension when bending is operated (or fracture).

The right contact spring of each bus contact according to bus terminal rows to being placed with different modes, to constitute the clamping contacts group of arranging and continuous with different power supplies (for example three of three-phase current phases) to have at interval.

For making the capable formation of contact spring linearly final products, the arm of contact spring must have different size and dimensions according to each bus terminal rows, so that the difference of compensation position in the bus terminal rows group that constitutes therefrom.

See on Fig. 2 and 3 as us, can settle a bus terminal rows shown in Figure 1 right on the limit of a bus terminal rows to group, it is adjacent with total binding post group and link to each other with the neutral line.

So and the integral body that forms provides a very compact connector, the density of contact spring is very large therein.Can support the electric current of 60A magnitude according to the connector of invention.In the industrial technology of big electric current, connector can have vast application.
