Description

[0001] The invention relates to a connector with a base body and a locking element which is rotatably mounted on the base body and with which the connector can be secured in a plugged-in position.

[0002] These connectors are well-known components in electrical engineering, such as cable glands and circular connectors. Connectors can be used, for example, as power and / or signal connectors.

[0003] The object of the invention is to improve connectors of the type mentioned above.

[0004] To solve the aforementioned problem, the features of claim 1 are provided according to the invention. In particular, to solve the problem in a connector of the type described above, it is proposed that a leaf spring exerts a force that counteracts a torque applied to rotate the locking element. This makes it possible, for example, to ensure that the locking element can only open or close when the torque exerted on the locking element is greater than the force exerted by the leaf spring. Thus, a locking mechanism for a connector can be created that opens and closes reliably, i.e., only when a user intends to open or close the locking mechanism.

[0005] The main body of the connector can be the part through which cables pass. The mated position can be the position in which the connector is in sync with a corresponding plug. Opening and closing the locking mechanism may require applying torque to the connector's locking element. This torque can be applied, for example, by hand or with a tool such as pliers.

[0006] In an advantageous embodiment, the leaf spring can be designed asymmetrically. This allows, for example, the torque required to open the closure (i.e., to rotate the closure element in one direction) to be greater or less than the torque required to close the closure (i.e., to rotate the closure element in another direction). In other words, opening and closing the closure can require different torques. To prevent accidental opening, for example, due to machine vibrations, opening can require a higher torque than closing. Alternatively or additionally, the leaf spring's mounting in the base body can be designed asymmetrically. This also allows for different required torques for opening and closing.

[0007] In an advantageous embodiment, the locking element may have a detent profile. This allows the locking element to be gripped particularly securely. The detent profile can also serve as a tool attachment point, enabling the locking element to be gripped with a tool. In particular, the locking element may have a detent lug. This, for example, can ensure that the locking element can be gripped particularly securely.

[0008] In an advantageous embodiment, the leaf spring can be designed to directly actuate the locking element. This allows, for example, direct contact between the locking element and the leaf spring, eliminating the need for additional components. This results in a less fault-prone locking mechanism. Assembly can also be simplified.

[0009] In an advantageous embodiment, the adjustment range of the locking element can be limited. This can, for example, create a defined range within which the locking element can be rotated. This can simplify operation for the user. It can also prevent the locking element from being over-rotated in one direction. Furthermore, the limitation can be advantageous because it allows the user to see when the end point of the locking element's rotation has been reached.

[0010] In an advantageous embodiment, the leaf spring can cover more than one-third of the adjustment range. This allows, for example, a uniformly distributed force to act from the leaf spring on the locking element.

[0011] In an advantageous embodiment, the leaf spring can be designed to form a sliding surface for the locking element. This can, for example, allow a surface of the locking element to slide over the sliding surface, enabling smooth opening and closing.

[0012] In an advantageous embodiment, at least one marking may be provided on the base body. This allows the user, for example, to see the position of the locking element, "open" or "closed". Alternatively or additionally, at least one marking may be provided on the locking element itself.

[0013] This allows, for example, the marking to indicate the position of the locking element in conjunction with the marking on the base body. For instance, an arrow could point to "close," so the user can see that the locking element is in the closed position.

[0014] In an advantageous embodiment, a connecting section can be rotatably mounted relative to the base body. This can, for example, reduce torsional forces or torques that may occur.

[0015] In an advantageous embodiment, the leaf spring can be formed in one piece. This can, for example, enable simple and cost-effective assembly. It can also make the production of the leaf spring more cost-effective.

[0016] In an advantageous embodiment, the locking element may be provided with at least one tool engagement point. Alternatively or additionally, the base body may be provided with a tool engagement point. Alternatively or additionally, the extension may be provided with a tool engagement point. This allows, for example, the locking element, the base body, and / or the extension to be actuated with a tool, for instance, to close or open a connection.

[0018] Fig. 1 Figure 1 shows a connector 1, which has a base body 2 and a locking element 3. The locking element 3 is rotatably mounted on the base body 2. The connector 1 can be secured in a mated position by the locking element 3. A leaf spring 4 exerts a force 5 that counteracts a torque 6 applied to rotate the locking element 3.

[0019] In another embodiment, the leaf spring 4 of the connector 1 is designed asymmetrically. A receptacle 7 for the leaf spring 4 is also designed asymmetrically in order to accommodate the leaf spring 4.

[0020] The locking element 3 has a locking profile 8 which has several locking lugs 9. Thus, the locking element 3 can be securely gripped by hand or with a tool.

[0021] Fig. 16 This shows that the leaf spring 4 directly acts on the locking element 3. Thus, the force 5 is directly transferred from the leaf spring 4 to the locking element 3, thereby counteracting the torque 5 and making it more difficult to rotate the locking element 3.

[0022] The adjustment range 10 of the locking element 3 is limited. Consequently, the locking element 3 can only move within a certain range.

[0023] The leaf spring 4 covers more than a third of the adjustment range 10. This allows the leaf spring 4 to be in contact with the locking element 4 over a large range of the adjustment range 10.

[0024] The leaf spring 4 forms a sliding surface 11 for the locking element 3. Thus, the locking element 3 can slide over the leaf spring 4. In doing so, the locking element 3 presses into the leaf spring 4, which is elastic and exerts a counter-pressure, the force 5, on the locking element 3.

[0025] Fig. 1 Figure 12 shows, by way of example, that a marking 12 is attached to both the locking element 3 and the base body 2.

[0026] An extension 13 of the connector 1 is rotatably mounted relative to the base body 2 of the connector 1.

[0027] Fig. 15 Figure 4 shows the one-piece leaf spring 4. In this embodiment, the leaf spring 4 is made of metal. However, manufacturing it from a plastic material also appears possible.

[0028] The locking element 3, the base body 2 and the extension 13 have tool engagement points 14.

[0029] Connector 1 of the Fig. 1-9 It has a deflection 15 that deflects cables running inside connector 1. Connector 1 of the Fig. 10-14 It features two deflections 15, which enables a 180° cable routing.

[0030] The connectors 1 shown each have a cable input end 16 and a plug end 17.

[0031] Fig. 10 shows that an interface 18 is formed, on which a part of the connector 1 is screwed to the plug end 17 and another part of the connector 1 is screwed to the cable input end 16.

[0032] The locking element 3 is rotatably mounted on the base body 2. The sectional view in Fig. 4 This rotatable mounting is shown. The base body 2 is also rotatably mounted relative to the extension 13, or rather, the extension is rotatably mounted relative to the base body 2. The connector 1 comprises a feedthrough arrangement 19 for the cables running inside the connector 1 (not shown). In the illustrated embodiment, this feedthrough arrangement 19 consists of an angled part 20, the cable entry end 16, and the plug end 17.

[0033] The exemplary embodiment of the Fig. 10-14 includes a second angled part 21 at the cable entry end 16.

[0034] The in Fig. 16 and 17 The illustrated installation situation of the leaf spring 4 shows that the locking element 3 has a lug 22 that points towards the interior of the connector 1. This lug 22 of the locking element 3 presses against the leaf spring 4 when the locking element 3 is opened and closed, compressing it. In a rest position, i.e., when the locking element 3 is fully open or closed, sides of the lug 22 press against a slope 23 of the leaf spring 4 and also against a shoulder 24 of the connector 1.

[0035] The locking element 3 can of course be rotated in two directions.

[0036] A connector 1 with a base body 2 and a locking element 3 is proposed, wherein the locking element 3 is rotatably mounted relative to the base body 2, wherein the connector 1 with the locking element 3 can be secured in a plugged position, wherein a leaf spring 4 exerts a force 5 which counteracts a torque 6 which is applied to rotate the locking element 3.
