Description

The main circuit that the low-voltage complete device is used patches the linkage function assembly

The utility model relates to the main circuit that a kind of low-voltage complete device uses and patches the linkage function assembly, belongs to a kind of line connector.

At present, the insulation function division board must be housed between horizontal bus compartment and the functional unit compartment in the low-voltage complete device fix vertical bus (the L shaped bus in right angle), just can reach the drawer multiloop and patch function.Not only volume is big for this function division board, and costs an arm and a leg, and the every cover price of the function division board of import is about 5500 yuan, and the every cover price of homemade function division board is about 3800～4000 yuan.So, patch the assembly of function with this multiloop, though can reach good performance,, be difficult to be accepted by users because of manufacturing cost is too high.

The purpose of this utility model is that a kind of volume is little, cost is low for the user provides, and has multiloop and patches the main circuit that function, low-voltage complete device stable and reliable for performance use and patch the linkage function assembly.

Task of the present utility model is achieved in that main circuit that this low-voltage complete device is used patches the linkage function assembly and partly is made up of fixed row folding functor, a fixed function of socket spare, touch base functor three, fixed row folding functor by row folding cover, row folding at the bottom of and bank of contacts formed, described row folding cover is one-body molded by a plurality of functional units, but between per two adjacent function unit, have webge contact row's right angle L type groove, have installing hole on each functional unit on the row folding cover, it is upper and lower corresponding with installing hole at the bottom of the row folding; In a fixed function of socket spare, have the U-shaped breach on front end two sidewalls of every functional unit socket, there is the two-sided slot that can insert one-time contact the rear end; The contact afterbody envelope curve diameter difference of one-time contact, can select according to current capacity; The centre of each functional unit on the socket and sidewall have one high and one low holder and gathering sill, make high and low the differing of one-time contact insertion depth on socket; Bank of contacts is being arranged in parallel on the pedestal of touch base functor, one end atresia of bank of contacts, can patch connection, the other end is porose, connect with the lead overlap joint, perhaps two ends are all porose, all connect with the lead overlap joint, division board on translucent cover and the corresponding end height of a porose end bank of contacts are low with the corresponding end of atresia one end bank of contacts.

Row folding cover of the present utility model is one-body molded by a plurality of functional units, have multiloop and patch function, the contact afterbody of one-time contact can the crimping different size lead with the needs of an amount of different current capacities, one end of bank of contacts adopts plug-in type, the other end adopts the lead overlapping mode to connect, and the user can adopt the different modes of connection according to different needs.Division board on the translucent cover can height differ by the bank of contacts mode of connection is different, reduced so greatly division board volume, reduced cost.

Accompanying drawing is a kind of embodiment of the present utility model.

Fig. 3 is a fixed row folding functor structural representation in the utility model.

Fig. 4 is the structural representation of touch base functor in the utility model.

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1 and Figure 2, the main circuit used of this low-voltage complete device patches the linkage function assembly and partly is made up of fixed row folding functor 1, a fixed function of socket spare 2, touch base functor 3 three.A fixed function of socket spare 2 inserts the bank of contacts 6 in the fixed row folding functor 1, the connection (as shown in Figure 1) that formation main circuit inlet wire patches.The bank of contacts 22 that a fixed function of socket spare 2 inserts in the touch base functor 3 forms the connection (as shown in Figure 2) that the main circuit outlet patches.Shown in the figure, this fixed function of socket spare 2 is four utmost points, and it is made up of socket 10 and one-time contact 11.The front end of socket 10 is four groups of U-shaped breach 12, and two-sided slot mode 13 is adopted in the rear end, can insert 8 one-time contacts 11 at most, has multiloop and patches function.The holder that the centre of each functional unit on the socket 10 has a pair of height to differ, at two sidewalls the different gathering sill of a pair of height is arranged, same mutually in, after two one-time contacts insert sockets 10, be in the different contact position of height, to prevent the contact point temperature overheating.One-time contact 11 is made up of contact 14, U-shaped spring 15 and lead 16.Contact patches place 17 and is some contact, increases elastic pressures by U-shaped spring 15, and each contact 14 head sectional area is identical, and its afterbody 18 is diversified in specifications with the overseam place of lead 16, can the crimping different size (generally at 70mm ²～10mm ²) lead, adapt to the different current capacities (needs of 400A～63A).

As shown in Figure 3, fixed row folding functor 1 by row folding cover 4, row folding at the bottom of 5 and bank of contacts 6 form, having on the row folding cover 4 at the bottom of the L shaped groove 7 in right angle, the row folding in 5 has cylinder location lug 8, and centre bore is arranged at bank of contacts 6 bottoms, it with this cylinder locate lug 8 mutually fit position installation.Have the countersunk head installing hole 9 of upper and lower correspondence at the bottom of row folding cover 4, the row folding on 5, in order to installing and fixing, and increase alternate creepage distance.

As shown in Figure 4, touch base functor 3 touches part 19 by pedestal 21 and bank of contacts 22 single injection-moldeds by touching part 19 and translucent cover 20 is formed.Have installing hole 23 on the pedestal 21, bank of contacts 22 is arranged in parallel within on this pedestal 21.Bank of contacts 22 has two kinds of forms, and it can be an end atresia 26, adopts to patch connection, and the other end has installing hole 25, adopts the lead overlap joint to connect, and perhaps two ends all have installing hole 25, adopt the lead overlap joint to connect.The user can adopt the different modes of connection as required.In the translucent cover 20 of touch base functor division board 24 is arranged, it can separate the alternate distance of bank of contacts 22, prevents to produce electric mist phenomenon.Division board 24 2 ends height is different, and corresponding to the porose end height of bank of contacts 22, an end of atresia is low, can reduce volume like this, reduces product cost.
