Definitions
- the present invention relates to a connector, in particular a crimp connector.
- Existing connectors such as crimp connectors, house multiple terminals internally, including power terminals, protective earth (PE) terminals, and keying terminals. Fewer terminals can be accommodated in the connector due to space limitations and relatively large protective earth terminals. Since the type of PE connector used is usually different from that of the power connector, the technicians need to additionally use a screw to fix the PE connector, resulting in a very cumbersome installation.
- PE protective earth

- the multiple ports further include power ports and coding ports; where the power connections and the protective earth connections are the same connection type.
- a particular advantage is that by additionally providing the protective earth plate, the installation of the protective earth connections in the insert housing is simplified, whereby the power connections can be used as protective earth connections. Because common power terminals are used as ground protection terminations, relatively more terminals can be accommodated in the insert case.
- the protective earthing plate comprises a middle section and two side wing parts that curve convexly from two opposite sides of the middle section, the middle section having a screw hole for screwing in a screw (50).
- each projection is formed on the two side wing parts, each projection being provided with a window.
- each side wing part comprises two projections located at both ends thereof.
- an arm is formed in one piece on one of the two projections, the movable end of the arm having a bending section.
- the arm extends in a plane in which the projections are located, the bending portion and the plane forming an angle.
- the arm can be formed separately directly on the side wing part.
- the arm and the projections are arranged separately from each other.
- the outer surface of a side of the insert housing used for attaching the protective grounding plate is designed in such a way that this outer surface is form-fitting with the protective grounding plate.

- the outer side walls of the rib parts each have two locking lugs located respectively at the two ends of the rib parts, the opening being located between the two locking lugs.
- the rib part has a
- Protective earth terminal and the protective earth plate made by the protective earth terminal coming into contact with the bent portion of the arm of the protective earth plate.
- a electrical connection made by screwing the screw into the screw hole of the middle section of the protective earth plate. This establishes a ground connection between the protective earth terminal and the screw through the protective earth plate.
- the shell is secured to the insert case by the screw to establish a ground connection between the shell and the protective earth terminal.
- the multiple terminals 13 comprise power terminals and one or two protective earth terminals.
- the multiple ports further include at least one coding port, such as one or two coding ports.
- connections can be accommodated in different numbers in the insert due to the spatial arrangement.

- the cavity of the insert housing 10 has a plurality of terminal receiving holes (see Figure 2) on the inside. 14 holes are shown in FIG. 2, and it goes without saying that the number of holes is not limited thereto. Each terminal-receiving hole has a respective terminal. Therefore, a plurality of terminals are accommodated in the insert housing 10, which are provided in a number of 14 in FIG. It goes without saying that the number of terminals is not limited to this.
- the connection here is a plug connection. Therefore, the insert 1 is a male insert while the connector is a male connector.
- the connector includes a power connector 30, a protective earth (PE) connector 31 (hereinafter abbreviated as PE connector) and a coding connector 32.
- PE connector includes a power connector 30, a protective earth (PE) connector 31 (hereinafter abbreviated as PE connector) and a coding connector 32.
- the power connector and the PE connector may be of the same type, such as e.g. E.g. a standard Han E crimp connection with a cross-section of 2.5 mm 2 .
- the multiple ports include at least one PE port, e.g. E.g. one or two.
- the terminal receiving holes include a power terminal receiving hole 20, a protective earth (PE) terminal receiving hole 21 (hereinafter referred to as PE terminal receiving hole 21), and a coding terminal receiving hole 22.
- FIG. 3 shows an exploded view of an insert according to FIG. 1. The main components of the insert are explained in more detail in connection with FIG.
- a circumferential groove for receiving a sealing element 60 is formed on an outer circumference of the insert housing 10 facing the plug-in side B.

- the side wing part 42 is formed in an inverted U-shape, with one side of the U-shape being formed integrally with the central portion and the other side forming at least two projections 43.
- a window 44 is arranged in the projection 43 .
- An arm 45 is integrally formed on one of the two projections 43, a fixed end of the arm is integrally formed with the projection 43, and a movable end has a bending portion 46 which bends inward and is in the form of a contact piece.
- the arm 45 can be separately formed directly on the side wing portion 42 .
- the PE sheet 40 may be snapped to the outer surface of the insert housing 10, i.e. both are in a form fit.
- the middle portion 41 of the PE board 40 is accommodated in the middle recess 11 of the cartridge case 10 and exposed to the outside.
- the center portion 41 is recessed relative to the surface of one side of the insert case 10 where the center portion is located to provide an installation space for the screw.
- the space formed between the middle section 41 and the bottom of the middle recess 11 can preferably be used to accommodate the coding connections 32 .
- the two side wing parts 42 of the PE panel 40 are respectively snapped onto the two rib parts 12 of the insert housing 10, with the locking lugs 13 of the rib parts 12 protruding into the window 44 of the projections 43 of the side wing part 42 to close the PE panel 40 on the insert housing 10 attach.
