Description

Electric contact element with engaging protrusion for plug housing (2)

The invention relates to an electrical contact element for a single-pole or multi-pole plug housing. The plug housing has at least one contact chamber and is composed of an electrically insulating material to accommodate at least one of the electrical contact elements (2). The electric contact element (2) has a fixing section (4) for fixing an electric wire, wherein the electric contact element (2) has a contact section (6) for conducting electricity with a corresponding opposite contact element Connection, wherein the electrical contact element (2) has at least one engaging protrusion (10), wherein the engaging protrusion (10) is displaceable from a first position to a second position, and vice versa from a second position The position is shifted to a second position; wherein the engaging protrusion (10) protrudes obliquely outwards when the first engaging position is in the first engaging position, and the engaging protrusion (10) can be engaged with the second engaging position when in the second engaging position; Contact room is engaged.

In order to make people better understand this prior art, the conventional techniques of the background of the invention will be described in detail with reference to the drawings.

Please refer to the "prior art" supplementary figure (Figs. 8A to 8C).

There is a conventional plug connector used in the prior art for conducting plugs. The plug connector mainly includes a contact chamber, and the contact chamber is made of an electrically insulating material to accommodate at least one of the electrical contact elements. , Wherein the electric contact element has a fixing section to fix an electric wire, wherein the electric contact element has a contact section to cause conduction with a corresponding opposite contact element Connection, wherein the electrical contact element has at least one engaging protrusion, wherein the engaging protrusion can be shifted from a first position to a second position, and vice versa from a second position to two second positions; Wherein, the engaging protrusion is protruded obliquely outward when in the first engaging position, and the engaging protrusion can be engaged with the contact chamber when in the second engaging position.

In the prior art, there is a conventional electrical plug-in element for creating a conductive plug. The electrical plug-in connector mainly includes a plug housing having a contact chamber, wherein each contact chamber can be provided with an electrical contact element. . In order to prevent the electrical contact element from being detached from the contact chamber improperly, the electrical contact element is snapped into the contact chamber. This engagement is achieved using an engagement projection. The engaging protrusion protrudes from the electric contact element, and is pressed back to a second position when the electric contact element is put into the contact chamber, and when the electric contact element has reached a predetermined position in the contact chamber Then, it bounces to a first position, and engages with the lower cut (Hinterschnitt, English: undercut) in the contact room. Generally, the engaging protrusions generally have a narrower shape, and this shape is represented by the electrical contact element.

Generally, the engaging protrusions have a relatively narrow shape and are presented by the electrical contact elements. However, before the electrical contact element is inserted into its related plug, the engaging protrusions may easily hook with adjacent contact elements and / or electrical wires due to its shape, which may cause plastic deformation of the engaging protrusions. It is in a curved form, so it is no longer possible to ensure that the engaging protrusions are normally in the contact room and the contact elements are normally engaged in the engaging room.

Therefore, there is a need to provide a contact element with an engaging protrusion, wherein the engaging protrusion and the adjacent element can be reliably prevented from being hooked on the opposite side.

It can be seen in FIG. 8A that a contact element (A) of the conventional plug connector has been inserted and fixed in a contact chamber (B), and the contact element has a barb-shaped engaging projection (C). The elasticity of its material will cause it to tilt upwards. Therefore, when the contact element (A) is inserted in the insertion direction (to the left in Figure A) When entering the contact chamber (B), the engaging projection (C) is first lowered to a lower second position, and when the engaging projection (C) passes the lower cutting portion (D) of the contact chamber, it is no longer It is pressed down and elastically rises upward, so that the top position acts as a barb on the wall of the undercut (D), so the contact element (A) can no longer be moved from the contact chamber (B) to the opposite direction (to the right) )pull out. If the contact element (A) is to be pulled out, a pointed object can be used to press down the engaging protrusion (C) to its second position, so that the contact element (A) can be pulled out to the right.

FIG. 8B shows a perspective view of the contact element of the prior art. The engaging protrusion (C) is not stressed, so it is upturned to the first position. In this conventional technique, the left and right of the engaging protrusion (C) are empty, so that adjacent wires or other things may run in and be caught, and even cause the engaging protrusion to be deformed. It is clear at a glance that it is compared with the embodiments shown in Figures 1, 2, 4, and 6 of the description of this case. According to the present invention, the left and right of the engaging projection are closed by the wing elements (34) (38), so there is no such disadvantage.

FIG. 8C shows a longitudinal sectional view of the contact element, the engaging protrusion (C) in the upper figure is in the first position, and the engaging protrusion (C) in the lower figure is in the second position.

The engaging protrusion can be integrated with other parts of the contact element. Due to the elasticity of the material (such as a metal sheet), the engaging protrusion (C) will return to the first position when it is not stressed, and will be stressed Can be pressed to the second position.

From the above drawings and descriptions, "how the engaging projection is shifted between the first and second positions" and "how the engaging projection is maintained at the second position" will be clear. Because the engaging protrusion is naturally left in its first position due to the elasticity of the material, it will be pressed to the second position only by pressure (for example, when the contact element is pushed into the contact chamber by the narrow channel part). When the contact element is engaged in the contact chamber, to remove the contact element from the contact chamber, the engaging protrusion can be pressed down to the second position from the slot above the contact chamber. Pulling out the contact element is similar to the method of engaging and releasing the latch by a general barb.

The state of the engaging protrusion in the second position is only a temporary state when the contact element is pressed into the contact chamber or is to be pulled out from the contact chamber. Therefore, there is no need to provide any means to keep the engaging protrusion in its second position.

Therefore, there is a need to provide a contact element with an engaging protrusion, wherein the engaging protrusion and the adjacent element can be reliably prevented from being hooked on the opposite side.

This demand can satisfactorily utilize the achievement of the subject of independent items in the scope of patent application.

According to a first embodiment of the present invention, there is an electrical contact element for a single-pole or multi-pole plug housing, which has at least one contact chamber and is made of an electrically insulating material to accommodate at least one of the electrical contact elements. Wherein the electric contact element has a fixing section for fixing an electric wire, wherein the electric contact element has a contact section to make a conductive connection with a corresponding opposite contact element, wherein the electric contact element has at least one card Engaging protrusion), wherein the engaging protrusion can be shifted from a first position to a second position, and vice versa from a second position to a first position; wherein the engaging protrusion is in the first card When in the engaged position, the obliquely protruding outwards, wherein the engaging protrusion can be engaged with the contact chamber when in the second engaging position.

A supporting element is connected to the engaging protrusion in a non-releasable manner, wherein a cavity is enclosed by the engaging protrusion and the supporting element, wherein the cavity is closed by a closing element in the first position, so that The hooking of the engaging protrusion is prevented.

By closing the cavity (which is formed by the engaging protrusion and the supporting element), the engaging protrusion of the electrical contact element can be prevented from being caught on another adjacent element, and the other side is utilized The electrical contact element can prevent, for example, the engagement protrusions of other contact elements according to the prior art from The engaging projections of the electrical contact element of the invention are hooked. The electrical contact element can also prevent the engaging projections from being hooked with the conductance or other elements. Since the engagement protrusion of the electrical contact element can be prevented from being caught on other components and other components can be caught on the engagement protrusion of the electrical contact element, it can be effectively prevented that the electrical contact element is Damage caused by other components. Here, the supporting element can be designed so that it can also effectively prevent hooking with other elements. The snap-in element can be firmly connected to a partial area of the electrical contact element with a first end, wherein the supporting element can be firmly connected to the second end (which is opposite to the first end). For example, the electrical contact The side view of the element can be designed so that the engaging protrusion and the supporting element constitute a triangle with two strands, and the partial region constitutes another strand. Here, parts of the area can be designed as boxes or flat. In order to close the cavity surrounded by the engaging protrusion and the supporting element, the cavity can be cast out of a casting material, for example. The cavity may also be closed with a plastic insertion element, or the cavity may be closed with a wing element, which is provided on the side edge of the engaging protrusion and / or the supporting element. The closing element is generally designed so that the combination formed by the engaging protrusion, the supporting element and the closing element does not form sharp edges or edges. Using this design can effectively prevent the electrical contact element from being installed and inserted into the housing. When taken out (a sealing net is provided on the plug card body), this sealing net is damaged.

According to another embodiment of the present invention, the closing element is formed by using a first wing element and a second wing element, wherein the engaging protrusion and the supporting element have a common first edge and a common second edge. The second edge is opposite to the first edge; wherein the first wing element is at least partially firmly connected to the first edge; wherein the second wing element is at least partially firmly connected to the second edge; wherein the first wing The element and the second wing element are designed so that neither the first wing element nor the second wing element protrudes beyond the engaging protrusion and the supporting element.

The first and second wing elements can be designed so that the wing elements are firmly connected to the support element. On the edge of the component or on the edge of the engaging protrusion, especially if the electrical contact element is designed as a stamped and bent part, the wing element can be bent out of the supporting element and / or the engaging protrusion. Generally, the wing element is designed so that a free partial area of the edge (that is, a portion that is not connected to the wing element) can be covered by the engaging protrusion or the supporting element without causing the wing element to protrude beyond the engaging protrusion. And supporting components. In addition, the first and second wing elements generally rest at least partially on the relevant free partial area of the edge. The wing element is designed so that the engaging protrusion can be displaced from the first position to the second position, and vice versa, it can be displaced from the second position to the first position without the wing element hindering the displacement.

According to another embodiment of the present invention, the closing element is formed by using a first wing element and a second wing element; wherein the engaging protrusion has a third edge and a fourth edge, the fourth edge and the third edge Opposite; wherein the supporting element has a fifth edge and a sixth edge, the sixth edge and the fifth edge are opposed to each other; wherein the third edge and the fifth edge are spaced apart from each other by a distance; wherein the fourth edge and the The sixth edges are spaced apart from each other; wherein the first wing element is firmly connected to a component, the component is composed of the third edge and the fourth edge; wherein a first of the first wing element faces away from the cavity. The outer side is at least partially on a plane with the element formed by the third edge and the fourth edge; wherein the second wing element is firmly connected with another component, and the other element is formed by the fifth edge and the sixth edge ; Wherein a second outer side of the second wing element facing away from the cavity and the fifth edge and the first Another component formed by the six edges is at least partially on a plane.

Here, the cavity can also be closed with the two-wing element in an advantageous manner, so that the engagement protrusion and / or the supporting element are hooked on other elements can be prevented.

According to another embodiment of the present invention, the first wing element is connected to the engaging element or on the supporting element, and the second wing element is connected to the engaging element or on the supporting element.

Therefore, there may be some shapes, in which, for example, the first wing element is connected to the supporting element and the second wing element is connected to the engaging element. Since electrical contact elements are generally designed as a stamped and bent part and are punched out by a flat metal sheet here, these designs are advantageous when the electrical contact element is provided on a metal sheet, because the stamped waste can be cut back. Furthermore, the snap-in element, the support element and the wing element can be made in one piece in an advantageous manner. Compared with the multi-piece design, this can effectively avoid cumbersome work and higher manufacturing costs.

According to another embodiment of the present invention, the electrical contact element has a substantially box-shaped partial region, wherein the box-shaped partial region has two mutually opposing side walls, a bottom element, and a cover element, and the cover element and the bottom element Opposite, and has an opening, the opening is surrounded by the side wall; wherein the side wall is connected with each other by the element and the cover element in a non-releasable manner; wherein the supporting element extends at least until the opening in the first position. ; Wherein the closing element extends at least until the opening.

Therefore, in the first position of the engaging protrusion, no element is caught between the closing element (or the supporting element) and the opening. However, in general, the closing element is designed such that, in the first position of the engaging protrusion, the side wall at least partially overlaps the closing element.

According to another embodiment, in the second position, the first wing element and the second wing element are shifted into the box-shaped partial area through the opening, so that the engaging element is substantially related to the cover element. Pieces on a plane.

Therefore, the engaging protrusion can be displaced to a part where the box-shaped partial area of the electrical contact element does not protrude. In this way, the electrical contact element can be removed from the plug housing in a particularly simple manner. Moreover, by using this design, the sealing net provided on the plug shell can be reliably prevented from being damaged.

According to another embodiment of the present invention, the supporting member has a protrusion, wherein the protrusion passes through the opening and the cover member is caught from the back.

With this protrusion, the engaging protrusion can be prevented from being displaced beyond the first position against the direction in which it is displaced from the first position to the second position in an advantageous manner. Therefore, it can be ensured that, even when an operator improperly utilizes the electric contact element, the engaging protrusion does not form some gaps with the supporting element and the closed cavity (the engagement of the electric contact element according to the prior art) (Protrusions or electrical leads may get caught in the gap).

According to still another embodiment of the present invention, in the second position, the protrusion and the bottom member cooperate with each other, so that the engaging protrusion cannot move from the first position to the second along a displacement direction of the engaging protrusion Out of position beyond this second position.

Therefore, the protrusion and the bottom element can be used to limit the displacement path of the engaging protrusion from the first position to the second position, so that the engaging protrusion cannot reach further displacement after reaching the second position. This limitation of the displacement path can prevent the engaging protrusion from being deformed beyond the elastic range during displacement. Particularly, the plastic deformation of the engaging protrusion can be prevented, so that the engaging protrusion can independently occupy the first position. Failure to reach the first position may prevent the electrical contact element from properly engaging in the contact chamber. Therefore, when the electric contact element is moved up on the electric opposing contact element, it may be pushed out from its contact room, and it will not or only have insufficient conductive connection with the relevant opposing contact element.

According to another embodiment of the present invention, the electrical contact element is a stamped and bent part.

Therefore, the electrical contact elements can be manufactured at low cost, and the electrical contact elements can be designed so that their cross-section is only about 1 square millimeter, resulting in a grid size of 1.5 mm (that is, from the center of the first contact element to The distance between the centers of the second contact elements adjacent to one contact element).

According to another design of the present invention, the electric contact element is a one-piece type.

The electrical contact element can thus be produced particularly inexpensively.

It should be noted that the concept of the present invention is described herein using an electrical contact element. Here, it is clear to the experts that the features described individually can be combined with each other in different ways, reaching other designs of the invention.

A perspective view of the embodiment; FIG. 7 is a longitudinal sectional view of the electrical contact element of FIG. 2, in which the engaging protrusion is displaced to a second position.

Figures 8A-C are instructions for the conventional plug connector.

Figure 1 shows an electrical contact element (2) with a fixed section (4) (for fixing an electrical conductor) and a contact section (6) (for causing electrical conduction with an associated opposing contact element) connection). The electrical contact element (2) has an engaging projection (8), which moves from a first position shown in the figure along a displacement direction V to a second position shown in FIG. In the first position, the engaging protrusion (8) protrudes obliquely outward. A supporting element (10) is connected to the engaging protrusion (8) in a non-releasable manner. A cavity (12) is enclosed by the engaging protrusion (8) and the supporting element (10). The cavity (12) is closed by a closing element (14) (designed as a casting material here), and the cavity (12) is closed, on the one hand, it can prevent the engaging protrusion (8) of the electrical contact element (2). ) Is hooked on other adjacent elements, and on the other hand prevents, for example, the engaging protrusions of other contact elements of the prior art and the electrical contact element (2) from being hooked. The engaging protrusion (8) has a first end (16) and a second end (18), and the first end (8) is connected to a cover element (28). The second end is opposite to the first end (16), and the supporting element (10) is firmly connected thereto. The cover element (28) has a substantially rectangular opening (30). In addition, the cover element (28) belongs to a box-shaped partial area (20), and the other is formed by a first side wall (22), a second side wall (24) (opposite the first side wall (22)), and a bottom element. (26) Composition. Here, the first side wall (22) and the second side wall (24) are substantially parallel to each other and extend along the displacement direction V. The first side wall (22) and the second side wall (24) are connected to each other by a bottom member (26) and a cover member (28). A protrusion (32) is formed on the supporting element (10), and it covers the cover element (28) from below, so the engaging protrusion (8) cannot be displaced beyond the first position against the displacement direction V. Therefore, to prevent the engaging protrusion (8) and other elements from being hooked, it is sufficient to use the cavity (12) with a closing element (14) (its cross-section is substantially triangular).

Fig. 2 shows the electrical contact element (2) of Fig. 1, wherein the cavity (12) is closed by two wing elements (34) (38) (which are opposed to each other and extend substantially parallel to each other). Support element (10) of Figure 3 The front view numbers the devices described below. The support element (10) extends approximately perpendicular to the displacement direction V, and is therefore approximately perpendicular to the cover element (28). The engaging protrusion (8) and the supporting element (10) have a common first edge (36) and a common second edge (40) [which is opposite to the first edge (36)]. In the embodiment shown here, a third edge (42) of the common first edge (36) restricts the engaging element (8), and a fifth edge (46) restricts the supporting element (10). In addition, A fourth edge (44) of the common second edge (40) limits the engaging element (8), and a sixth edge (48) limits the supporting element (10). The first wing element (34) is firmly connected to the third edge (42) of the engaging protrusion (8), and the second wing element (38) is firmly connected to the fifth edge (46) of the engaging protrusion (8). ). The wing element (34) (38) shown here not only closes the cavity (12), but also extends in the direction of the bottom element (26) through the opening (30) into the box-shaped partial area (20). The first wing element (34) has a first inner side (58) facing the cavity (12), and the second wing element (38) has a second inner side (60) also facing the cavity (12) . Since the electrical contact element (2) is designed as a one-piece stamped and bent part, the way the two-wing element (34) (38) is arranged on the engaging protrusion (8) makes the inner side (58) (60) at least approximately lean against On the edges (46) (48) of the support element (10). A wing element (34) (38) is provided here which projects beyond a front side (41) of the support element (10).

4 and 5 show another embodiment of the electrical contact element (2) shown in Figs. 2 and 3. Here, the two-wing element (34) (38) is also firmly connected to the engaging protrusion (8), but here the fifth edge (46) of the supporting element (10) is better than the first edge of the engaging element (8). The three edges protrude more in the direction of the first side wall (22). The third edge (42) and the fifth edge (46) are therefore spaced. Correspondingly, the sixth edge (48) of the supporting element (10) protrudes more than the fourth edge of the engaging projection (8) in the direction of the second side wall (24). Therefore, the fourth edge (44) and the sixth edge (48) are spaced apart. The first wing element (34) has a first outer side (50) opposite the first inner side (58), and the second wing element (38) has a second outer side (52) opposite the second inner side (60). The first wing element (34) and the second element (38) are provided on the engaging protrusion (8), so that the supporting element (10) covers the second wing element (34) (38). Therefore, the first outer side (50) of the first wing element (34) is substantially on a plane with the fifth edge (46) of the support element (10), and the second outer side (52) of the second wing element (38) Approximately on a plane with the sixth edge (48) of the support element (10). With this design, the engaging protrusion (8) can also be prevented from being caught on other elements.

FIG. 6 schematically shows the electrical contact element of FIG. 4. The first side wall (22) and the second side wall (24) each have an edge (62), and the opening (30) is surrounded by the edge. In this embodiment, the first wing element (34) and the second wing element (38) are designed so that they are closed with an edge (62) when in the first position, so the extensions shown in FIGS. 4 and 5 are not required ( 54) To prevent the engaging element (8) from being hooked with other elements.

FIG. 7 shows a longitudinal sectional view of the electrical contact element of FIG. 2, in which the engaging protrusion (8) is displaced in a displacement direction V from a first position to a second position. The contact section (6) here has two opposing contact plies (56). When in the second position, the engaging protrusion (8) and the cover element (28) are on the same plane. In order to prevent the engaging protrusion (8) from continuing to move beyond the second position in the displacement direction, the protrusion (32) stops. Stop on the bottom element (26).

With the embodiment described here, on the one hand, the engaging protrusions (8) of the electrical contact element (2) can be reliably prevented from hooking with other components, and on the other hand, the engaging protrusions (8) can be prevented from moving along the displacement direction. Shift beyond the second position. Such an excessive displacement will plastically deform the engaging protrusion (8) or the cover element (28), so the engaging protrusion (8) can no longer enter the first position independently.
