Definitions

• the invention relates to an electrical connector having a first connector part, which has a first housing with electrical contact elements, with a second connector part, which has a second housing with electrical mating contact elements, with a guide sleeve, with the end portions of the first and the second connector part are connected, and a bayonet ring on the first and / or the second connector part for locking at least one connector part to the guide sleeve.
• Such a connector is known from DE 198 30 672 A1 and is provided for example for connection of transmission control systems in motor vehicles.
• a socket is designed as a lockable connector part.
• a particularly advantageous embodiment of such a connector part shows the DE 198 30 671 A1.
• bayonet ring allows a quick and secure connection of two connector parts or a connector part with a guide sleeve.
• additional locking means also referred to as secondary locking.
• secondary locking For connectors which are interlocked and latched by a linear movement, this is usually a displaceable in or against the insertion direction latch provided which blocks the position of the primary connection producing latching elements in a locking position.
• a locking button is slidably disposed on the circumference of the bayonet ring, which has at least one displaceable in the direction of the guide sleeve pin which cooperates with an outer surface profile of the guide sleeve.
• the locking button can only be brought into its final locked position when the bayonet ring is already in its final locked position. As soon as the locking button is in its final locked position, the primary locking mechanism produced by the bayonet ring can no longer be released. To release the Primärverrastung the locking button must be pulled back into their Vorrastsander.
• Locking button is immediately recognizable whether the bayonet ring is in its final locked position. An accidentally incomplete primary lock can thus be easily avoided.
• FIG. 1 shows a guide sleeve
• FIG. 2 shows a locking button
• FIG. 1 shows a guide sleeve (7) of an electrical connector which, in the installed state, connects two non-illustrated connector parts to one another.
• the connection of the second connector part at the lower end portion of the guide sleeve (7) can be done in principle in the same way; But the second connector part can also be attached to the guide sleeve (7) in any other way, in particular by a screw or locking connection, or even be integrally connected thereto.
• the guide sleeve (7) has the shape of a hollow cylinder and has on its outer surface a molded surface profile. To this surface profile include several at one end portion of the guide sleeve (7) arranged, spirally guided along the outside longitudinal slots (4) which extend to the front edge (21) of the guide sleeve (7) and terminate there in recesses, each having a transverse slot (5 ) in the front edge (21) form.
• pin-shaped projections on one, belonging to the first connector part bayonet ring in the transverse slots (5) are inserted and guided by turning the bayonet ring along the longitudinal slots (4).
• the bayonet ring (8) which is shown in a plan view in Figure 3, has for this purpose a guide sleeve (7) cross-collar, which carries on its inside the in the longitudinal slots (4) engaging pin-shaped projections.
• the longitudinal slots (4) have in the region of their lower end portions in each case a latching edge (6), so that when turning the Bayonettrings (8) reaching the final locked position is recognizable as a resting process.
• a locking button (9) which shows the figure 2 in a single part illustration.
• the locking button (9) consists of an actuating plate (14) and two perpendicular thereto arranged side walls (15) whose shape is such that the actuated locking button (9) as good as possible on the circumference of the bayonet ring (8).
• a latching hook (11) and two pins (10) are formed, which cooperate with the surface profile of the guide sleeve (7). This is shown in detail in FIG.
• the sub-figures 3a and 3b show the bayonet ring (8) in an unlocked or in the locked position relative to the guide sleeve, while the sub-figures 3b and 3c by the position of the lock button (9) (operated / unactuated) differ.
• the subfigures 3a to 3c each show a plan view of the bayonet ring (8), together with a within the bayonet ring (8) arranged and with the bayonet ring (8) connected to the socket housing (3).
• the female housing (3) serves to receive electrical contact elements (2) which are provided with connecting wires can.
• the socket housing (3) and the bayonet ring (8) thus form together the first connector part (1).
• the bayonet ring (8) has a circumferential collar which projects beyond the outside of the guide sleeve (7) shown in FIG.
• the socket housing (3) connected to the bayonet ring (8) dips into the opening of the guide sleeve (7).
• the locking button (9) On the outside of the bayonet ring (8), the locking button (9) is slidably disposed, whereby by actuation of the locking button (9) the molded thereon pins (10) and the latching hook (11) in the direction of the guide sleeve (7) can be moved ,
• the displacement direction is at an angle of approximately 45 ° to the radial direction and thus forms a compromise between a radial displacement direction, which would allow too small actuating travel, and a tangential
• the free end portions of the pins (10) each, based on the plane of the actuator plate (14), inclined surfaces (22), whose plane is parallel to the tangent plane at the point of contact between the pins and the surface of the guide sleeve (7), resulting in a maximum contact surface between the pins (10) and the guide sleeve (7).
• FIG. 3a shows the bayonet ring (8) immediately after insertion into the bayonet guide, ie in the still unlocked position.
• the middle locking lug (12) of the latching hook (11) abuts against an edge (19) formed on the bayonet ring (8), whereby the locking button (9) can not be displaced in the direction of the guide sleeve (7).
• the locking button (9) is thus initially immovably fixed in its initial position.
• the bayonet ring (8) is finally locked in the bayonet guide in a clockwise direction after being rotated by 90 °.
• the position of the bayonet ring (8) relative to the guide sleeve (7) is well recognizable here by the change in position of the rotary lever (16).
• the rotary lever (16) also serves as an actuating aid, especially for gaining power when locking the bayonet lock.
• the locking button (9) can now be moved in the direction of the guide sleeve (7), whereby the inside of the actuating plate (14) on the outer wall of the bayonet ring (8) comes to rest. This is a correctly set secondary lock and thus the previously made error-free primary connection of
• FIG. 3c shows the locking button (9) in its end position.
• the end section of a pin (10) integrally formed on the locking button (9) engages in a pocket-shaped receptacle (20) which is formed by the surface profile of the guide sleeve (7) in this area.
• the bayonet ring (8) is locked relative to the guide sleeve (7).
• the pocket-shaped receptacle (20) as well as the raised portion (23) of the end edge (21) of the guide sleeve (7) have also been designated in FIG. 1 for clarity.
• FIG. 3c further shows that the locking button (9) is secured by a double latching connection which is secured on the one hand by the edge (19) on the bayonet ring (8) and the middle latching lug (12) on the latching hook (11)
