Definitions
- the invention relates to a connector having a contact carrier with at least two contact chambers, in each of which a contact partner is inserted and primarily locked there, with at least one locking tab having at least one locking pin, with a respective contact partner locking secondarily in its contact chamber with one locking pin is, according to the features of the preamble of claim 1.
- a connector of this type is known from DE 101 57 564 A1.
- This known connector has a contact carrier with at least two contact chambers (in this case two rows with four contact chambers each).
- a contact partner is used in each contact chamber and is primarily locked during this process. This is done, for example, in a manner known per se by a resilient tab protruding from the contact partner, which comes to rest against an undercut in the contact chamber. The resilient tab is pushed back slightly when the contact partner is inserted into the contact chamber and can protrude again when the contact partner has reached its intended position in the contact chamber. The so-called primary locking is thus implemented.
- a so-called secondary locking of the contact partners takes place.
- a locking tab is present, which in this case is arranged on the contact carrier.
- the locking tab (in this case two locking tabs arranged opposite one another) has a locking hook at its free protruding end, this locking hook initially being spaced from the contact carrier as long as the locking tab is not yet in its intended end position. This end position is only reached when each contact partner has been inserted into its associated contact chamber and primary locked there.
- the locking tab is then moved into its intended end position so that its latching hook can secondarily lock the contact partner located there by dipping into the contact chamber.
- the intended end position of the locking tab on the contact carrier is also permanently assumed at the same time.
- this known connector is relatively small, so that the respective contact chambers have a cross section of a few square millimeters (for example a cross section of two by two millimeters).
- the individual contact chambers are only separated from one another by relatively narrow webs, for example with a width of one to three millimeters.
- the invention is therefore based on the object of improving such a known connector in such a way that the disadvantages described at the outset are clearly avoided.
- a slot is arranged between two contact chambers in the contact carrier and the locking tab has a web, the web dipping into the slot when the locking tab is in its intended position on the contact carrier.
- the slot runs essentially parallel to the longitudinal axis of the contact chamber. It extends over the entire length of the contact chamber, but can also be shorter or extend over a greater length in the contact carrier.
- the slot in the contact carrier increases the path for the leakage currents that occur, so that flashovers between contact partners of adjacent contact chambers are significantly reduced and ideally completely avoided. This effect is increased by the fact that a web dips into this slot. This immersion is simplified during the assembly of the connector if the respective web, which is assigned to each slot, is located on the locking tab.
- the at least one locking pin (referred to as a latching hook in the prior art, although other terms can also be used for the means for the functionality of the secondary lock) and the at least one web on the locking tab, when the locking tab is in its intended end position on the Contact carrier is brought, realized at the same time both the secondary locking and the immersion of the web in its associated slot, whereby only a single assembly step is required for the secondary locking and to reduce rollover.
- the at least one locking tab is pivotably arranged on the contact carrier. This has the advantage that the contact carrier, together with its contact chambers and the locking tab, can be manufactured as a one-piece component.
- the contact carrier must have insulating properties and is therefore made of a plastic material, a plastic injection molding process is recommended.
- the locking tab is arranged on the contact carrier via a thin connection, for example in the form of a film hinge, and its free end initially protrudes a little from the contact carrier after production. Only when the contact partners have all been inserted into their associated contact chambers and primarily locked there is the locking tab pivoted from its protruding position into its intended end position, the secondary locking and the immersion of the at least one web in its associated at least one slot taking place simultaneously.
- a frame which is fixed to the contact carrier, the at least one locking tab being pivotably arranged on the frame.
- At least one locking tab possibly also several locking tabs, is pivotably arranged in one piece on the frame.
- the frame is also geometrically designed in such a way that it can be fixed in a suitable manner on the contact carrier, for example at the end face in the direction of the plug face of the connector. This setting takes place, for example, by gluing, pressing, locking or the like.
- the locking tab can also be manufactured and mounted as an independent component detached from the contact carrier and / or the frame and thereby fulfill the function of both secondary locking and the insertion of the webs into the tip.
- a minimum free space remains between the surface of the web and the surface of the associated slot when the web is immersed in its slot. This extends the creepage distance again and the minimal free space in the form of an (albeit very small) volume of air creates additional insulation with which the flashovers between the neighboring contact partners are significantly reduced or even prevented.
- This effect is preferably further increased in that the web (and possibly the entire locking tab on which the at least one web is arranged or by which it is formed) and the contact carrier are formed from different materials. This creates a dielectric, which significantly reduces flashovers again.
- a locking tab with its webs (or possibly only the webs) made of different materials with regard to the contact carrier can be produced, for example, by a known two-component injection molding process.
- a connector 1 which has a contact carrier 2.
- the contact carrier 2 two rows of each are exemplified five contact chambers 3 and a row with four contact chambers 3 are arranged.
- the number of contact chambers and rows is not restrictive and can be single-row, double-row or even multiple-row, with the number of contact chambers 3 also being able to be selected according to the area of application of the connector 1.
- the connector 1 according to FIG. 1 also has at least one locking tab 4, here a total of four locking tabs 4. These locking tabs 4 can be arranged directly on the contact carrier 2 (not shown in FIG. 1).
- the embodiment shown is that the connector 1 comprises a frame 5, the four locking tabs 4 extending from this frame 5 and protruding somewhat from the contact carrier 2 with their end region.
- the frame 5 in turn is arranged at the upper end of the contact carrier 2, which forms the plug face of the connector 1, from where a mating connector (not shown) can be plugged into the connector 1.
- a reverse arrangement of the locking tab 4 directly on the contact carrier 2 or a reverse arrangement of the frame 5 on the contact carrier 2 is also conceivable, for example by attaching the frame 5 to the end of the contact carrier 2 facing away from the mating face. It is important for the invention that the contact carrier 2 has at least two contact chambers 3 which are adjacent to one another and in which the contact partners (not shown) are secondarily locked via a locking pin, a locking hook, a locking strip or the like of the locking tab 4.
- FIG. 2 the details of the connector 1 are shown with improved protection against flashover voltage.
- the Frame 5 with its locking tabs 4 shown in isolation.
- the contact carrier 2 is shown with its several contact chambers 3, the frame 5 being placed on the contact carrier 2 and fixed there in a suitable manner (for example by latching).
- the essential details are locking pins 6 (also to be referred to as locking hooks or the like) and webs 7, which in this case run between the individual locking pins 6.
- locking pins 6 also to be referred to as locking hooks or the like
- the Locking tab 4 have further latching means, not shown, with which it is fixed in its intended position on the contact carrier 2 after the pivoting process.
- Figure 3 is a plan view of the contact carrier 2 from the direction of the mating face (ie from above into the contact chambers) is shown.
- the slot 8 through which the creepage distance is significantly lengthened can also be seen there.
- the submerged web 7 is not yet shown in this illustration.
- the cross-sectional geometries as shown in FIG. 3 are likewise only exemplary and can vary depending on the application of the connector 1.
- FIG. 4 shows the secondary lock in the closed state. It can be seen here that the frame 5 has been arranged at one end of the contact carrier 2 and has been fixed in a suitable manner. The locking tabs 4 are also pivoted into their intended end position and have also been fixed in this in a suitable manner. As a result, the secondary locking of the contact partners in their respective contact chambers 3 and the dipping of the webs 7 on the inside of the respective locking tab 4 into the associated slots 8 in the contact carrier 2 took place at the same time.
- the individual elements of the plug connector 1 according to the invention can advantageously be manufactured in a process-reliable manner and in large numbers in a plastic injection molding process from a suitable plastic material.
- Various polarizations and codings can be implemented in the shaping of the connector 1, in particular the contact carrier 2 and / or the frame 5.
- the connector 1, as shown in Figure 4 (but omitting the contact partners in the contact chambers and corresponding electrical lines), can be plugged together with a correspondingly designed mating connector to form a plug connection. Plugging together is a simple plug-in process that can be supported by an additional locking mechanism (CPA: connector position assurance).
- CPA connector position assurance
- the invention relates once again to a connector that has a contact carrier that comprises at least two contact chambers into each of which a contact partner is inserted.
- the contact partner is locked once in the contact chamber by means of its own locking tab (so-called primary locking).
- primary locking there is a secondary lock, which has the effect that the contact partner inserted into the contact chamber is fixed in the contact chamber in addition to the primary lock (so-called secondary lock).
- secondary lock is designed to fix the contact partner one more time in the contact chamber and also to provide protection against high-voltage flashovers between two adjacent contact partners.
