Definitions

• the invention relates to a plug connector with an insulation body, which has an essentially rectangular cross section and on the upper side of which a plurality of electrical contact tracks lying in a plane and extending in the plugging direction are arranged, which when the plug connector is joined together with a mating plug its corresponding contact springs lying next to each other interact and establish an electrical contact.
• USB Universal Serial Bus
• the basic principle is no longer to connect peripheral devices to a PC via individual, parallel connections with separate and often different connector systems as before, but rather to connect the peripheral devices essentially serially to a common bus.
• Connect the line which is directly connected to a PC board (motherboard) via a standardized socket on the PC housing.
• the face of the circuit board socket (receptacle) is essentially already specified by a specification and has four strip-shaped contact springs lying side by side in one plane, which, when the bus plug is plugged in, with the four contact rails arranged next to each other or tracks cooperate and establish the electrical contact.
• the contact springs are arranged in the socket plug in an insulation body, which is essentially designed as a plastic tongue with a rectangular cross-section, and are angled in their rear area towards connecting legs protruding downwards, which come into contact holes in the conductor plate are insertable.
• the connector and mating connector are usually provided with a metallic shield housing. Two latching hooks are provided in the ceiling and floor area of these shield plates, which engage in recesses on the shield housing of the matching mating connector and which realize the holding forces when the plug is pulled out and the ground contact.
• the object of the present invention is to solve the described contacting problem.
• tact tracks is designed as a curved sliding surface for the associated contact spring, that the insulation body is designed with a stepped offset at its plug-side end, the transition between the height levels at least in the area of the contact tracks matching their curved shape Sliding surface, that is, as a rounded step, and that the contact tracks are firmly arranged in the insulation body by extrusion coating with plastic.
• FIG. 1 shows a perspective partial view of a connector according to the invention
• FIG. 2 shows a partially sectioned view of the plug connector according to FIG. 1
• FIG. 3 shows a schematic section of the plug connector and a corresponding mating plug in the unplugged state.
• FIG. 1 shows an insulation body 1 which has a stepped offset 4 at its plug-side end, so that the contact tracks 2 arranged at the higher level end in front of the plug-side end of the insulation body 1. This does not form a closed front on the plug side, but is open in the plug opening area.
• the contact tracks 2 are each formed with a curved sliding surface 3. This and the open front area of the insulation body 1 provide protection against sharp-edged and / or abrasion-related contact contact when plugging in with the mating plug, since the contact point 7, which is also usually rounded, of the contact spring of the socket plug with the Sliding surface 3 cooperates and no longer has one sharp front edge of Isolations Congress ⁇ 1 must be moved.
• the dislocation 4 or the free surface formed thereby have the effect that the slightly sagging incoming contact spring does not come into contact with the insulating body 1 before contact with the sliding surface 3.
• the insulating body 1 should be designed such that it is set back in all surfaces that could interfere with the insertion.
• the insulation body 1, as can be seen in FIG. 1, is formed with side edges 5, the height of which is dimensioned such that the plastic tongue 8 (cf. FIG. 3) of the mating connector slips exactly at the intended height when inserted over these side edges 5, so that the contact elements 3, 7 of the socket and the plug come into contact with one another as intended.
• the repeated shifting back of the two middle contact tracks relative to the outer contact tracks is due to the fact that usually the outer contact tracks are used as power connections and should form a contact in time before the internal signal contacts.
• the rounded contact points 7 touch offset contact areas 6, which are arranged approximately in the middle of the contact tracks 2.
• the contact tracks By injection molding the contact tracks with plastic, they are held in position and cannot lift off the insulation body 1, which is particularly important with regard to the curved sliding surface 3. As can be seen in FIG. 1, the tip of the sliding surface 3 is anchored in the area of the offset 4 in the insulation body 1. Injection molding also has the advantage that an additional assembly process (inserting the contact tracks) is not necessary.
• FIG. 2 the two right-hand contact tracks 2 are shown in a (fictitious) non-overmolded state for better understanding.
• FIGS. 1 and 2 only show the plug area of the connector.
• FIG. 3 shows the plastic tongue 8 and the contact point 7 of the contact spring of the mating connector, which is somewhat sagging downward.
• the connector according to the invention is shown here with a shield plate 9. When plugged in, the plastic tongue 8 lies over the insulation body 1.
