Description

Technical Field

[0001] The present invention relates to an arrangement unit according to the features of the preamble of claim 1, comprising elements and corresponding elements inserted together, the elements having at least one opening, and a component of the corresponding element being inserted into the opening. Background Technology

[0002] For example, an element is a contact carrier of a plug connector, and a corresponding element is a corresponding plug connector, wherein contacts, particularly contact sockets, are arranged in the contact carrier, and corresponding contacts, particularly rectangular contact pins (also called blades), are arranged in the corresponding plug connector, wherein the contact pins are inserted into the contact sockets by means of plugging the plug connector with the corresponding plug connector.

[0003] The insertion process proceeds along the axial direction of the contact point. For example, in Figure 1 This embodiment is illustrated in five series of diagrams. It can be seen that the element, particularly the contact carrier, has an opening into which a component of a corresponding plug-in connector (not shown), particularly an elongated contact, should be inserted. It is shown that the component of the corresponding element is precisely aligned with the opening of the element, allowing the component of the corresponding element to be smoothly inserted into the opening, around which a trapping funnel (multiple surrounding, each straight, beveled surface) is arranged.

[0004] In practice, it may happen that the corresponding plug-in connector is not always correctly aligned / oriented relative to the plug-in connector position for the mating process. Therefore, the corresponding plug-in connector may be placed at an angle or slightly twisted, making it difficult, or even impossible, to insert the contact pin of the corresponding plug-in connector into the relevant opening in the contact carrier, in which the contact socket is arranged. Here, the front side of the contact carrier is typically damaged around the opening for inserting the contact pin. Figure 2 The two diagrams show the twisting of the components of the corresponding element (the contact pins of the corresponding plug connector) relative to the opening in the element (the contact carrier of the plug connector).

[0005] exist Figure 3 The six diagrams illustrate other possible torsions and the resulting damage to the trapping funnel in the component. On the left (viewed from bottom to top) is an opening in the component (contact carrier) with a trapping funnel (surrounding the bevel). Observation Figure 3The second, third, and fourth figures from the left illustrate the process in which a component of the corresponding element (the flat contact pin of the plug connector) is not accurately inserted into the opening in the element (the contact carrier of the plug connector). Therefore, when the end face of the component of the corresponding element rests against the surrounding ramp, it either causes damage to the surface of the element's end face or damage to the surface in the ramp region of the element, as shown in... Figure 3 As can be seen in the last two diagrams from the left (the material breaking off in the upper left and lower right parts of the slope). Incorrect orientation can even hinder the insertion process. Summary of the Invention

[0006] Therefore, the object of the present invention is to improve the process of inserting the components of a corresponding element into an opening of a component so that the insertion process is performed smoothly and damage to the components is avoided. In particular, the object of the present invention is to insert the contact pin of a corresponding plug connector into the opening and contact socket of a contact carrier (in which a contact socket corresponding to the contact pin is arranged) without damaging the contact carrier of the plug connector or the contact pin of the corresponding plug connector.

[0007] This objective is achieved through the features of claim 1.

[0008] According to the invention, a surrounding ramp is provided around the opening of the element, wherein the ramp has a larger width (i.e., expansion) in each of its end regions compared to its central region. This forms a trapping funnel, which is preferably elongated and has a wider width in each of its end regions than in its central region. Due to the larger width in its end regions, the trapping funnel allows for the purposeful guidance of the torsional components of the corresponding element, particularly the slightly torsional contact pins of plug-in connectors, through the ramp of the trapping funnel, and into the opening of the element, particularly the contact carrier, thereby guiding it to a predetermined alignment position.

[0009] It is particularly advantageous to use the retractable capture funnel of the present invention in plug connectors (which are inserted into a corresponding plug connector to form a plug connection in the mated state), because in practice, plug connectors are often not placed and inserted 100% axially (i.e., obliquely) onto their corresponding plug connectors. With the present invention, this initial axial offset of the contact mating part of the plug connector relative to the geometry of its corresponding contact mating part or the relevant contact carrier of the corresponding plug connector is compensated for, and the plug connector is aligned when it is initially placed on the corresponding plug connector and then guided to be mated together with the corresponding plug connector. This effectively avoids damage, especially to the area surrounded by the contact mating part or the corresponding contact carrier. Attached Figure Description

[0010] The prior art and embodiments of the present invention will now be described, with reference to the accompanying drawings.

[0011] The attached diagram shows:

[0012] Figures 1 to 3 It is an implementation method of the prior art, and

[0013] Figures 4 to 6 This is an embodiment of the present invention. Detailed Implementation

[0014] The beginning of the instruction manual states that... Figures 1 to 3 The prior art shown is described.

[0015] Figure 4 The five figures illustrate the construction design of the trapping funnel of the present invention in the contact carrier of an element, particularly a plug-in connector, which can also be referred to as a contracting inlet ramp. Figure 4 As can be seen in the series of diagrams, the slender contact pins are precisely aligned with the openings in the contact carrier, and therefore can be inserted without problems, without the need for a funnel. Figure 5 As can be seen in the two diagrams, the elongated contact pin was initially not accurately aligned with the opening of the contact carrier at the start of the insertion process, and therefore slightly twisted. This inherent misalignment / orientation was eliminated by having the end face of the contact pin contact the slope of the capture funnel widened at its end, thus ensuring that the contact pin was correctly positioned relative to the opening of the contact carrier during further insertion. Therefore, damage to the end face of the contact carrier or its capture funnel was effectively avoided, and the insertion process could proceed continuously and smoothly.

[0016] exist Figure 6 The eight separate diagrams show further detailed illustrations of the capture funnel of the present invention and its working principle when the elongated contact pin is inserted into the opening of the contact carrier.

[0017] Although the accompanying drawings, for example, show a plug-in connector with a contact carrier (which has at least one contact chamber for receiving contacts, particularly a contact socket) and a corresponding plug-in connector with its contacts, the invention can be modified such that a capture funnel with a contraction is also provided on the surrounding housing of the corresponding element, particularly the corresponding plug-in connector, so that when the element, particularly the plug-in connector, is inserted into the corresponding element, particularly the corresponding plug-in connector, the surrounding edge of the contact carrier of that element, particularly the plug-in connector, is guided into the capture funnel, and, for example, the contact carrier position is correctly aligned and further guided. This capture funnel on the housing of the corresponding element can be provided as a supplementary or alternative to a capture funnel around the opening of the element.

[0018] The constricted guide ramp in the component, especially the contact carrier, can also be used for circular contacts, which also produces an improved insertion situation because circular contacts - depending on the plug system - may also have a certain swing clearance.

[0019] The aspect ratio of the contact cross-section shown in the attached figure is approximately 5:1. This is merely an example. Contacts with other ratios, up to 1:1 (i.e., a square cross-section), can also be used to compensate for oscillation clearance not only in the case of slender, especially long and flat contacts (so-called blades), but also in the case of contacts with a near-square or perfectly square cross-section.

[0020] The accompanying drawing shows a contact carrier with a single opening for receiving the contacts, illustrating the basic principle of a capture funnel with a contraction. It goes without saying that this basic principle can also be applied to plug connectors with multiple contacts arranged side-by-side, and, where necessary, to dual-row or multi-row plug connectors.

[0021] As an alternative, the at least one contact socket may also be arranged in a corresponding plug connector, and the at least one contact pin may be arranged accordingly in the contact carrier of the plug connector.

[0022] The contact carrier forms a plug-in connector, or the contact carrier may be arranged in the housing.
