Definitions
- the present invention relates to a device according to the preamble of claim 1, i.e. a circuit board zero-power connector with an actuating element, by the actuation of which the circuit board zero-force connector can be brought from a mounting position that allows the insertion or removal of a circuit board into a connection position that properly contacts the circuit board and / or vice versa.
- Printed circuit board zero force connectors are used to connect two printed circuit boards electrically and mechanically to one another essentially without force; They are used, among other things, to be able to simply and gently plug a first printed circuit board essentially vertically onto a second printed circuit board (for example a so-called rear wall printed circuit board) and to connect them electrically and mechanically firmly and reliably to the latter.
- PCB zero force connectors have long been known in a variety of forms; a circuit board zero force connector which in the preamble of
- Claim 1 claimed type is described for example in US-PS 3 130 351.
- the circuit board zero-force plug connector known from this publication is fixedly mounted on one of the circuit boards to be connected to one another and is designed so that the other of the circuit boards to be connected to one another can be inserted therein. It is constructed in such a way that it can be brought into the connecting position by actuating an actuating element in an assembly position which permits the insertion or removal of a printed circuit board, and by inserting a printed circuit board. Attempting to insert or remove a circuit board in the circuit board zero force connector in the connection position can easily damage the circuit board and / or the circuit board zero force connector. If, on the other hand, one forgets to bring a printed circuit board zero-force plug connector with the inserted printed circuit board into the connection position, the printed circuit boards to be connected cannot come into proper contact. Both are understandably undesirable.
- the present invention is therefore based on the object of developing the circuit board zero-force connector according to the preamble of claim 1 in such a way that the risk of damage to the circuit board and / or the circuit board zero-force connector and / or the risk of an incorrect connection of the connection PCBs to be brought can be reduced to a minimum.
- a folding part is provided on the actuator, which can be folded back and forth between a locked position, in which it stands in the way of inserting or removing a printed circuit board into and out of the printed circuit board zero-force connector, and an open position that does not block the printed circuit board is, when folding into the locked position and / or when folding into the
- the open position strikes an element of the arrangement containing the circuit board zero-force plug connector in such a way that the actuating member is actuated along with the flaps.
- circuit board zero force connector can then and only then be in the mounting position or is automatically moved to the mounting position if and as long as the folding part is not in the way of inserting or removing a circuit board in or out of the circuit board zero force connector, and or
- circuit board zero-force connector can then and only then be in the connection position or is automatically moved to the connection position if and as long as the folding part is in the way of inserting or removing a circuit board in or out of the circuit board zero-force connector.
- the insertion or removal of a circuit board in or out of the circuit board zero-force connector can therefore only take place if and as long as it is in the mounting position; in the connecting position of the circuit board zero-force connector, the folding part stands in the way of inserting or removing a circuit board into or out of the circuit board zero-force connector.
- the blocking of a circuit board inserted in the circuit board zero force plug connector can be connected or coupled by folding the folding part over with bringing the circuit board zero force plug connector into its connecting position.
- the risk of damage to the circuit board and / or the circuit board zero-force connector and / or the risk of an incorrect connection of the circuit boards to be connected can thus be reduced to a minimum.
- FIG. 1 shows an exploded view of an arrangement containing the circuit board zero-force plug connector according to the invention
- Figure 2 is a perspective view of an actuator for the circuit board zero force connector according to
- Figure 3 is a perspective view of the actuator according to Figure 2 with the folding part located in the open position.
- circuit board zero-force connector described in more detail below is designed to electrically and mechanically connect two circuit boards which are to be arranged essentially perpendicular to one another (which are to be plugged vertically to one another).
- the application of the circuit board zero-force connector according to the invention is not restricted to such applications; the circuit boards, which can be connected by circuit board zero-force connectors of the type described, can in principle assume any relative positions.
- the zero force plug connector described in more detail below is designated by the reference number 1 in the figures.
- the circuit boards that are to be connected by this circuit board zero-force connector 1 are a first circuit board 3 and a second circuit board 4, the first circuit board 3 should be able to be plugged onto the second circuit board 4 essentially perpendicularly.
- Printed circuit boards in the manner of the second printed circuit board 4 are, for example, the so-called rear wall printed circuit boards; the attachable on it Printed circuit boards in the manner of the first printed circuit board 3 are often referred to as plug-in cards in accordance with their assembly.
- the circuit board zero force connector 1 is fixedly mounted on the second circuit board 4 using a mounting plate 2.
- the circuit board zero-force connector 1 and the second circuit board 4 are connected to one another both mechanically and electrically firmly and reliably.
- the circuit board zero-force connector 1 contains two connector halves 11 and 12 (hidden in the figures) which are separated from one another by an elongated slot 13.
- the first connector half 11 and the second connector half 12 are (even when the printed circuit board zero-force connector 1 is mounted on the second printed circuit board 4) by actuating a swivel mechanism 14 which is provided on the side of the printed circuit board zero force connector 1, but is not described in detail here, towards and away from one another swiveling or folding.
- the connector halves 11 and 12 By pivoting the connector halves 11 and 12 together, they move towards one another at the upper end of the circuit board zero-force connector 1 as shown in FIG. 1, as a result of which the slot 13 becomes narrower. If and as long as the slot is so narrowed, the first printed circuit board 3, which may be inserted therein, is clamped more or less firmly there and thus comes over the conductor plate zero force connector 1 electrically and mechanically in connection with the second circuit board 4; the electrical connection between the circuit board zero-force connector 1 and the first circuit board 3 is thereby pressed by pressing contact springs of the circuit board zero-force connector 1 which are pivotable (not shown in the figures) together with the connector halves 11 and 12 (also not shown in the figures) Surface contacts of the first circuit board 3 accomplished.
- Printed circuit board guiding devices are provided on two opposite sides of the printed circuit board zero force connector 1, with the aid of which (between which) the first printed circuit board 3 can be guided in or out of the slot 13 of the printed circuit board zero force connector 1; only one of the circuit board guiding devices is shown in the figures.
- This circuit board guide device designated by the reference number 5, can be mounted by means of mounting plates 6 and 7 on the housing or frame accommodating the arrangement shown, the housing or the frame in the
- an element referred to as an actuating element 8 is inserted into it, which at the same time serves as a guide element of the circuit board guide device 5 and as an actuating element for actuating the Swivel mechanism 14 of the circuit board zero force connector 1 is used;
- an actuating element 8 is inserted into it, which at the same time serves as a guide element of the circuit board guide device 5 and as an actuating element for actuating the Swivel mechanism 14 of the circuit board zero force connector 1 is used;
- each of the circuit board guiding devices can be equipped with such or a similar actuator 8.
- the actuating member 8 is an essentially rod-like element (a push and pull rod) which has a substantially U-shaped cross section in the central part 81, that is to say except at its two end sections 82 and 83.
- the middle part 81 is dimensioned such that it can be inserted into the circuit board guiding device 5, more precisely a space 51 provided for it, in such a way that the actuating element 8 is freely displaceable in the longitudinal direction of the same, but otherwise has very little freedom of movement within the circuit board guide device 5;
- the printed circuit board guide device 5 and / or the actuating member 8 and / or the mounting plates 6, 7 are designed such that the actuating member 8 is or can be secured against falling out and / or being pulled out of the printed circuit board guide device 5.
- a groove-like recess 84 is defined by it on the side of the printed circuit board guide device 5 facing the printed circuit board, in which the first printed circuit board 3 to be guided by the guide device 5, as in the figures 2 and 3 can be illustrated.
- the actuating member 8 acts as a guide element of the printed circuit board guide device 5.
- the end section facing the circuit board zero-force connector 1 in the assembled state ie the end section of the actuating element 8 designated by the reference numeral 82, engages with the swivel mechanism 14 when used as intended such that an actuation, ie a movement of the actuating element 8 in the longitudinal direction an opening and closing of the connector halves 11 and 12 of the circuit board zero force connector 1 is caused.
- the engagement between the end portion 82 of the actuator 8 and the pivot mechanism 14 is designed so that these elements are at least either in the mounting position or in the connecting position of the printed circuit board zero force connector 1 with each other (detached); the actuator 8 can thereby completely independent of the circuit board zero force Plug connector 1 can be inserted into or removed from the arrangement at any time together with the printed circuit board guide device 5 or without it.
- the end section facing away from the PCB zero-force connector 1 in the assembled state i.e. the end section designated by the reference symbol 83 of the actuating element 8 projects beyond a circuit board inserted into the circuit board zero-force plug connector 1, more precisely beyond the rear edge thereof with respect to the insertion direction, and in the example under consideration is provided with a folding part 85 which resembles a two-armed lever. As will be described in more detail later, this folding part 85 serves to facilitate the displacement of the actuator 8 in its longitudinal direction and / or to coordinate with the insertion / removal of a printed circuit board (the printed circuit board 3).
- the displacement of the actuator 8, i.e. pushing or pushing the same to the PCB zero-force connector 1 or pulling it away from the PCB zero-force connector 1 must be carried out if the PCB zero-force connector 1 is to be brought from the mounting position into the connecting position or vice versa.
- the circuit board zero force connector 1 has the mounting position. In this position, a printed circuit board under the guidance of the printed circuit board guide devices 5 can be inserted between the opened connector halves 11 and 12 of the printed circuit board zero-force connector 1 essentially without force.
- the actuator 8 To remove the circuit board from the circuit board zero-force connector 1, the actuator 8 must be pulled away from it. Characterized the pivot mechanism 14 is actuated so that it brings the circuit board zero-force connector 1 from the connecting position into the mounting position.
- the connector halves 11 and 12 of the same which are folded together in the connection position of the circuit board zero-force connector 1, open and enable the circuit board inserted into the circuit board zero-force connector 1 to be removed essentially without force.
- the actuation of the actuator 8, i.e. pulling it out to bring the circuit board zero force connector into the mounting position and pushing it in to bring the circuit board zero force connector into the connection position is, as has already been indicated above and will be explained in more detail below, by the folding part 85 facilitates and / or coordinate with the insertion / removal of a circuit board (circuit board 3).
- the folding part 85 can be folded back and forth between a locking position shown in FIG. 2 and an opening position shown in FIG. 3, the folding part 85 located in the locking position being a circuit board 3 which may be inserted into the circuit board zero-force connector 1 as illustrated in FIG. 2, or, to put it more generally, stands in the way of inserting or removing a printed circuit board into or out of the printed circuit board zero-force connector 1, and the folding part 85 in the open position being used to insert or remove a printed circuit board not hindered or blocked.
- a printed circuit board can only be inserted into or removed from the zero force plug connector when the folding part 85 is in the open position shown in FIG. 3; otherwise the folding part 85 would stand in the way of the circuit board to be inserted or removed and block it.
- the actuating element 8 is automatically in a position pulled away from the circuit board zero-force plug connector 1, as a result of which it assumes its unfolded assembly position. If and as long as the folding part 85 is in the open position, a printed circuit board to be inserted into or removed from the printed circuit board zero-force connector 1 can always be used as intended, i.e. be inserted into or removed from the circuit board zero-force connector 1 essentially without force and without risk of damage.
- the circuit board to be inserted or removed in the circuit board zero-force plug connector 1 is equipped with a pulling and pushing lever 31 at its rear end with respect to the insertion direction.
- This pulling and pushing lever 31 is the element on which or by means of the plug-in cards in the manner of the printed circuit board 3 are usually held, pushed, pulled and / or locked in the end position during assembly or disassembly. be animals; it is a movably fastened element on the printed circuit board, which is folded over into the printed circuit board zero-force connector after the correct insertion of the printed circuit board and thereby locks the printed circuit board.
- the folding part 85 is positioned such that it can only be folded into its locked position when a circuit board to be removed from the circuit board zero-force connector 1 is removed or when a circuit board to be inserted into the circuit board zero-force connector 1 is properly inserted into the latter and the pulling and Push lever 31 of the circuit board is folded out of the folding area of the folding part 85.
- the folding part 85 with the actuating element 8 connected to it cannot be pressed towards the printed circuit board zero-force connector if and as long as the folding part 85 is in the open position.
- the hinged part 85 abuts one of the mounting plates 6, 7 and / or the frame accommodating the arrangement or the housing accommodating the arrangement and / or another preferably fixed element in such a way that it is impossible to move it towards the zero-force plug connector is.
- circuit board zero force connector 1 can not be brought into its connecting position if and as long as a circuit board to be inserted there is not properly inserted. This prevents that the circuit boards to be connected are not or only partially connected against the external appearance.
- the folding part 85 If the folding part 85 is folded from the open position into the locked position, it can be pressed together with the actuating element 8 connected thereto to the circuit board zero-force connector; the large printing area that the Folding part 85 offers after folding it into the locked position, quasi a request to the operator to press the actuator 8 by exerting a pressure force on the pressure surface formed by the folding part 85 to the circuit board zero force connector.
- a snap-in process indicates that the connection position has been reached (audible and tactile).
- the folding part 85 covers the pulling and pushing lever 31 already mentioned above of the printed circuit board 3 inserted in the zero-force plug connector 1.
- the element is on or through that the circuit board 3 is usually held, pushed, pulled, locked and / or unlocked during assembly or disassembly, not accessible, which in turn means that the circuit board 3 is not or at least not easily removed from the circuit board zero-force connector can if and as long as the folding part 85 is in the locked position.
- the folding part 85 must first be brought into the open position. As long as the folding part 85 is in the locked position, it is impossible to insert or remove a circuit board in the circuit board zero-force connector; the clear visibility of this fact from the outside ensures that no attempts are even made to insert a circuit board into the circuit board Insert or remove power connectors. Damage to the circuit board zero-force connector and / or the circuit board, which is due to the fact that an attempt is being made to assemble or disassemble circuit boards with the circuit board zero-force connector in the connecting position, can therefore be reliably excluded.
- the circuit board zero-force connector is automatically in the assembly position when and as long as the folding part 85 is in the open position. If, in fact, the folding part 85 and the actuating element connected to it are pushed towards the circuit board zero-force connector 1, that is to say the circuit board zero-force connector 1 assumes the connecting position, the folding part 85 becomes the opening position together with the actuating element when the latter is folded 8 automatically pulled away from the PCB zero force connector 1.
- the structure of the arrangement is in fact chosen so that the folding part 85, more precisely its lever arm that does not engage behind the circuit board and is preferably shorter, in the locked position and pressed toward the circuit board zero-force connector in such a way to one of the mounting plates 6, 7 and / or the Arrangement receiving frame or the arrangement receiving housing and / or another preferably fixed element strikes that a pivoting movement of the folding part 85 can act as a one-armed lever, which performs a pivoting movement around the attachment point and thereby the actuating member 8 of the circuit board zero force connector moves away.
