Description

Contact tube with lamella
Technology area
The invention relates to contact tubes located in sockets and plugs properly furnished with pins providing electric current transmission. This comes under automotive equipment with electric joining parts such as truck tractors for trailers and/or semi-trailers.
Present technology status
Till now, the contact tubes were manufactured as simple turned part made from rod material of circular cross section originating long tube with 2 cut grooves fixed in the broken part from outside by a ring. Compression results in cross-section reduction and thus in contact with a plug pin. However, oval shape arising from original circular cross section fails to provide this contact in a perfect way. The second disadvantage consists in greater length of tube resulting in higher material consumption.
Invention subject matter
The invention subject-matter is a contact tube with lamella comprising a tube of cylindrical shape made by sheet metal shaping ended on one side by a crimping part for conductor while the tube itself is equipped with a part seating into a shell before the crimping part for conductor, cut locking element of contact into a shell, uniformly spaced within the surface on perimeter deflected from the surface outwards from the crimping part for conductor and locking parts for lamella and moreover it consists from a lamella comprised flexible plates anchored in a rim while the lamella is inserted in the tube from the opposite side to the crimping part for conductor. The subject-matter of invention is double sided locking of lamella preventing its extraction therefore locking parts for lamella are located both from the opposite side of tube from crimping part for conductor and in positions above locking elements of contact into shell or in a distance identical to lamella length.
The number of locking parts for lamella on both sides is at least three ones and similarly the locking contact elements of contact into shell are three ones as minimum.
Summary of figures in drawings Figure 1 shows the contact tube with lamella for pin of 4.0 mm diameter. Figure 2 shows contact tube with lamella for pin of 4.8 mm diameter. Figure 3 shows the long contact tube with lamella for pin of 6.4 mm diameter.
Examples of implementation
Example 1:
This is an example of contact tube with lamella for the pin of 4 mm diameter (Figure 1) comprising tube I of cylindrical shape, made by metal sheet shaping that is ended on one side by crimping part U. for conductor. Tube I of cylindrical shape is equipped with part J.J3 seating into a shell before crimping part J_J_ for conductor, cut locking elements .L2 of contact into shell, uniformly spaced within the surface on perimeter deflected from the surface outwards from crimping part (1.1) for conductor and locking parts L4 for lamella located in positions above the locking parts L2 of contact into shell and from the opposite side of tube I from crimping part J_J_ for conductor. Tube I accepts inserted lamella 2 comprising flexible plates 2J_ anchored in rim 2.2. Locking parts YA for lamella lock lamella 2 from both sides after inserting tube L The number of locking parts YA for lamella on both sides is three ones and similarly the locking contact elements Y2 of contact into shell are three ones.
This contact tube with lamella is made from brass sheet metal. The crimping part serves for accommodation a conductor of cross-section 1.0 to 2.5 mm2 It is used as a contact tube ABS 15 pol, 24 V.
The contact tube with lamella provides better conductive connection due to lamella application. To produce this, less material is used in comparison with contact tube with 2 cut grooves.
Example 2
This is an example of contact tube with lamella for pin of 4.8 mm diameter (Figure 2) performed by sheet metal shaping. The contact tube with lamella is similar to that from Example 1, however, it has larger external diameter for the same length. It is proper for plugs 7 pol, 24 V. The contact tube with lamella provides better conductive connection due to lamella application. To produce this, less material is used in comparison with contact tube with 2 cut grooves.
Example 3 This is an example of long contact tube with lamella for pin of 6.4 mm made by sheet metal shaping. The long contact tube is similar to that from Example 1, however, the total length is 48.8 mm with 8 mm external diameter (Figure 3). It differs in location of locking part IA^ for lamella that is located opposite to locking elements 1.2 of contact into the shell but considering its length, in the distance that is identical to lamella length. The contact tube is seated in the centre of contact insertion. It is proper for plugs 7 pol, 24 V.
The contact tube with lamella provides better conductive connection due to lamella application. To produce this, less material is used in comparison with contact tube with 2 cut grooves.
Industrial applicability
The contact tube with lamella is used for 24 V into plugs 15 pol, 13 pol for lighting of trailers, 5 pol for ABS and/or EBS brakes and 7 pol only for lighting circuit.
