Plug connector and method for preassembly thereof
View Patent ↗The invention relates to a plug connector with contacts having a connecting end for a cable, a housing and a lid. The housing and the lid each have a flap at the level of the connecting end of the contacts, wherein the connecting ends of the contacts can be freely accessed when said flap is in its open position in order to fasten the cable.
1. A plug connector, having
contacts, each with a connecting end for a cable, wherein the connecting end comprises a first side and an opposite second side,
a housing comprising a first opening and a second opening, wherein the first opening is proximate the first sides of the connecting ends, and wherein the second opening is proximate the second sides of the same connecting ends, and
a lid,
is hereby characterized in that
the housing and the lid each have a flap at the level of the connecting end of contact, when the flaps are in a closed position, the flap of the housing is at the first opening and the flap of the lid is at the second opening, and when these flaps are in the open position, the connecting ends of contacts are freely accessible for fastening the cable, wherein the first side of the connecting end is configured to contact a first portion of a tool proximate the first opening, wherein the second side of the connecting end is configured to be deformed by a second portion of the tool proximate the second opening, and wherein the contacts are fully engaged in the housing when the flaps are in the open position.
2. The plug connector according to claim 1 , further characterized in that the housing and the lid are made of plastic, and the flaps are linked by hinges of thinner material to each of the former, respectively.
3. The plug connector according to claim 1 , further characterized in that the flap of the lid has catch brackets laterally on both sides of the lid and these brackets lock with corresponding catch pieces on the lateral walls of the housing in the closed position of the flap of the lid.
4. The plug connector according to claim 1 , further characterized in that the flap of the lid has catch elements on a top side of the lid, which can be locked with complementary catch elements when the flap of the lid is in the open position.
5. The plug connector according to claim 4 , further characterized in that the upper flap on aid has catch elements on its top side, which can be locked with complementary catch elements on a yoke of a secondary lock when flap is in the open position and when yoke is in the assembly position.
6. The plug connector according to claim 1 , further characterized in that flap on lid has molded pieces, which press the cable ends mounted on the back end of housing in strain relief into this relief when lid is locked.
7. The plug connector according to claim 1 , further characterized in that flap on housing has catch shoulders on its lateral edges running perpendicular to swiveling axis, and these shoulders lock in corresponding grooves in housing.
8. The plug connector according to claim 1 , further characterized in that the cable ends, stripped of insulation, are joined with contacts by crimping, whereby crimping is conducted with the complete assembled plug connector and opened flaps.
9. The plug connector according to claim 1 , further characterized in that lid and housing are fastened via lateral catch shoulders/catch arms either to one another or to a part of lid.
10. The plug connector according to claim 1 , further characterized in that flaps are arrested in open position by retaining ribs with predetermined breaking points at the joining edges between housing or lid and flaps, respectively, which stand open.
11. The plug connector according to claim 1 , further characterized in that the lower flap is arrested on housing in open position by means of a reversible locking between catch elements on flap and complementary catch elements on the housing.
12. A method for the preassembly of a plug connector according to claim 1 is hereby characterized by the combination of the following steps:
a) inserting contacts into housing;
b) fastening lid on the housing, with opened flaps;
c) fastening cable ends to the connecting ends of contacts by crimping or soldering; and
d) closing flaps.
13. A plug connector, having
contacts, each with a connecting end for a cable, wherein the connecting end comprises a top side and an opposite bottom side,
an uptake, which surrounds the connecting ends of contacts,
is hereby characterized in that
the uptake has an opening at the top side and an opening at the bottom side of the connecting ends at the level of connecting end of contact, and at least one of these openings can be closed by a flap, in the open position of which, the connecting ends are freely accessible for the fastening of cable, wherein the opening at the top side is configured to allow for deformation of the top side by a crimping tool, and wherein the opening at the bottom side is configured to allow for the bottom side to contact a crimping anvil.
14. The plug connector according to claim 13 , further characterized in that uptake can be formed in one piece.
15. The plug connector according to claim 13 , further characterized in that uptake also surrounds the plug or socket ends of contacts.
16. The plug connector according to claim 13 , further characterized in that the uptake has two flaps for closing both openings.
17. The plug connector according to claim 1 , further characterized by a catch device for the reversible retaining of one flap in the open state.
18. The plug connector according to claim 13 , further characterized by a catch device for the reversible retaining of one flap in the open state.
19. A plug connector comprising;
a housing comprising a first opening and an opposite second opening;
a lid attached to the housing, wherein the lid is configured to cover the second opening; and
a contact between the housing and the lid, wherein the contact comprises a connecting end, wherein a first side of the connecting end is accessible through the first opening, wherein the first opening is configured to allow a crimping anvil to extend therethrough and contact the first side, wherein an opposite second side of the connecting end is accessible proximate the second opening, and wherein the second side is configured to be deformed by a tool.
