Description

Technical Field

[0001] Cross - reference to Related Applications This disclosure is provided based on Chinese Patent Application No. 202223564141.5 filed on December 30, 2022, and claims the priority of the above - mentioned Chinese patent application. The entire content of the application referred to above is incorporated herein by reference.

[0002] This disclosure relates to the field of wire harness connection technology, specifically to connectors, connector assemblies, and vehicles.

Background Art

[0003] A lever (pull rod) - connector assembly usually includes a first housing (female housing), a second housing (male housing), and a lever. The lever is pivotally connected to the housing by a pivoting mechanism, and the lever has a primary locking position (preliminary locking position) and a secondary locking position (locking position) with respect to the housing. When the female housing is assembled to the male housing, a cam - follower arranged on the housing is mounted on a cam member arranged on the lever, pulling the lever from the primary locking position to the secondary locking position. As a result, the female housing is firmly connected to the male housing.

[0004] When the lever - connector is in the secondary locking position, a cantilevered hanging table of the housing is mounted and locked to the lever joint. The position where the lever rotates forward and stops is implemented by fitting the key groove of the lever and the key of the housing. However, the fitting gap between the key groove and the key expands along the lever. As a result, the lever rotates excessively forward, and the insertion holes of the lever and the housing cannot accurately overlap, making it difficult to insert a cable tie or wire.

Modes for Carrying Out the Invention

[0023] Embodiments of the present disclosure are described in detail below, examples of the embodiments are shown in the accompanying drawings, and elements that are the same or similar, or have the same or similar functions, are represented by the same or similar reference numerals throughout the description. The embodiments described below with reference to the accompanying drawings are exemplary only, and are intended only to describe the present disclosure and should not be construed as limiting the present disclosure.

[0024] A connector according to one embodiment of the present disclosure is described below with reference to the accompanying drawings.

[0025] Figure 1 is a schematic diagram of a unidirectional connector according to one embodiment of the present disclosure. The connector includes a female housing and a male housing. When the female housing is assembled to the male housing, the female housing is locked to the male housing by a lever mechanism, and as a result the assembly is mounted. For example, in the embodiment of the present disclosure, the first housing 1 is configured to mean the female housing, and in other embodiments, the first housing 1 may alternatively mean the male housing. This is not limited to this embodiment.

[0026] As shown in Figure 1, the connector 100 includes a first housing 1 and a lever mechanism 2. The lever mechanism 2 is rotatably connected to the first housing 1 and has a pre-locking position and a locked position relative to the first housing 1. The lever mechanism 2 includes two side levers 21 and an intermediate locking lever 22 connecting the two side levers 21, with locking projections 212 positioned on each of the two side levers 21. The first housing 1 includes two side walls 11, with locking recesses 114 corresponding to the locking projections 212 provided on each of the two side walls 11. The locking projections 212 and the locking recesses 114 are such that the lever mechanism 2 remains in the pre-locking position of the first housing 1. Fitting The first housing 1 further includes an upper wall 12, and in response to the lever mechanism 2 remaining in the locked position of the first housing 1, the locking projection 212 abuts against the upper wall 12 of the first housing 1 to limit excessive rotation of the lever mechanism 2.

[0027] Specifically, the locking recess 114 is provided in the first housing 1, and the locking projection 212 is located on the lever mechanism 2. Therefore, the primary locking of the first housing 1 to the lever mechanism 2 is performed between the locking recess and the locking projection. FittingThis can be implemented by doing so. In addition, during the secondary locking of the first housing 1 to the lever mechanism 2, the locking projection 212 of the lever mechanism 2 may be configured to abut against the upper surface or the edges of two sides of the upper surface of the first housing 1 to limit excessive forward rotation of the lever mechanism 2, and to ensure alignment between the insertion hole of the first housing 1 and the insertion hole of the lever mechanism 2 so that the insertion of cable ties or metal wires can be completed more easily. It may be found that “excessive rotation of the lever mechanism 2” in this disclosure may be understood as excessive forward rotation of the lever mechanism 2 that misaligns the insertion hole of the first housing 1 and the insertion hole of the lever mechanism 2.

[0028] Accordingly, in the connector 100 according to the embodiment of the present disclosure, locking projections 212 are arranged on each of the two lateral levers 21, and locking recesses 114 corresponding to the locking projections 212 are provided on each of the two side walls 11. The locking projections 212 are positioned such that the lever mechanism 2 remains in a pre-locked position on the first housing 1 and the locking recesses 114 Fitting In response to the lever mechanism 2 remaining in the locked position of the first housing 1, the locking projection 212 abuts against the upper wall 12 of the first housing 1 to limit excessive rotation of the lever mechanism 2. The connector 100 can be precisely positioned to align the insertion holes and improve the locking force of the connector 100.

[0029] In some embodiments, the two lateral levers 21 are provided with rotating shaft bearing holes 215, and the corresponding rotating shafts 112 are located on the two side walls 11 of the first housing 1. The lever mechanism 2 is rotatably connected to the first housing 1 by the fitting between the rotating shaft bearing holes 215 and the rotating shafts 112. The rotating shafts 112 are mounted in the rotating shaft bearing holes 215, forming a rotation mechanism, and as a result, the lever mechanism 2 can rotate relative to the first housing 1. Alternatively, the rotating shafts may be located on the lateral levers 21, and the rotating shaft bearing holes are provided on the side walls 11 of the first housing 1, forming a rotation mechanism.

[0030] For example, the lever mechanism 2 is rotatably connected to the first housing 1 by a rotation mechanism and is detachable from it. For example, one end of each of the two lateral levers 21 of the lever mechanism 2 is connected by an intermediate locking lever 22, which extends beyond the outside of the first housing 1 and is configured to rotate outside the first housing 1 while the connector 100 is locked. The two lateral levers 21 and the intermediate locking lever 22 are usually integrally formed.

[0031] More specifically, as shown in Figure 3, each of the lateral levers 21 has a first arm 211 and a second arm 213 connected to each other. A rotating bearing hole 215 is provided in the first arm 211. The second arm 213 extends axially from the first arm 211, and a locking projection 212 is located on the second arm 213. When the lever mechanism 2 is in the pre-locked position, one end of the first arm 211 extends forward and downward and is attached to the corresponding rotating shaft 112, and an intermediate locking lever 22 is connected to one side of each corresponding second arm 213. The first arm 211 and the second arm 213 of each lateral lever 21 extend linearly. In some embodiments, the first arm 211 and the second arm 213 may alternatively be positioned at a particular angle. For example, the first arm 211 and the second arm 213 may form an obtuse angle.

[0032] In some embodiments, each lateral lever 21 has a first arm 211. As shown in Figure 3, one end of the first arm 211 has a meshing tooth shape with a toothed structure 216 on its outer surface. In other embodiments, the end may alternatively have a groove shape. A rotating bearing hole 215 in the lateral lever 21 is provided in the first arm 211. At least one lateral lever 21 has a second arm 213, which extends axially from the first arm 211. A locking projection 212 is provided in the second arm 213. The side wall 11 of the first housing 1 is provided with a locking recess 114 corresponding to the locking projection 212 in the second arm 213. The locking projection 212 and the locking recess 114 are provided to form a pre-locking mechanism. Fitting When the locking projection 212 is positioned in the locking recess 114, the lever mechanism 2 is in a pre-locking position relative to the first housing 1 and has a certain holding force, which in turn prevents the lever mechanism 2 from being separated from the pre-locking position by minor collisions during packaging, transport, and assembly.

[0033] In some embodiments, the locking projection 212 may be configured as a projection of any shape. For example, the locking projection 212 may be cylindrical, conical, or cubic in shape, as long as the locking projection 212 can form a pair with the locking recess 114 to implement the locking function. This is not limited to this embodiment.

[0034] In some embodiments, the locking recess 114 may be a groove or a projection receiving hole, and the locking recess 114 is provided by the groove or projection receiving hole for the locking projection 212 so that the lever mechanism 2 remains in a pre-locking position on the first housing 1. Fitting It will be done.

[0035] Furthermore, the locking projection 212 has an arc-shaped transition surface, and the two side edges of the upper wall 12 of the first housing 1 have rounded edges. In response to the lever mechanism 2 remaining in the locked position of the first housing 1, the arc-shaped transition surface of the locking projection 212 abuts against the rounded edges to limit excessive rotation of the lever mechanism 2.

[0036] In some embodiments, the first housing 1 is provided with a first through-hole 13, and the lever mechanism 2 is provided with a corresponding second through-hole 214. The locking projection 212 abuts against the upper wall 12 of the first housing 1 so that the second through-hole 214 of the lever mechanism 2 is aligned with the first through-hole 13 of the first housing 1, thereby increasing the secondary locking force between the lever mechanism 2 and the first housing 1 by inserting a retaining structure and securing the connector 100 in response to the lever mechanism 2 remaining in the locked position of the first housing 1.

[0037] Specifically, when the first housing 1 is aligned with the paired second housing 5 (as shown in Figures 6 and 7), the toothed structure 216 located on the lever mechanism 2 aligns with the toothed structure of the paired second housing 5. The lever mechanism 2 is rotated so that the toothed structure 216 drives the first housing 1 into the paired second housing 5. When the lever mechanism 2 rotates to the locking position (as shown in Figure 7), the first housing 1 is fully inserted into the paired second housing 5 in a predetermined position, and the secondary locking of the lever mechanism 2 is implemented. The arcuate transition surface of the locking projection 212 of the lever mechanism 2 abuts against the upper wall 12 of the first housing 1 or the rounded edges of the two sides of the upper wall 12. This ensures that the second insertion hole 214 of the lever mechanism 2 is basically aligned with the first insertion hole 1 of the first housing 1, so as to limit excessive forward movement of the lever mechanism 2 and to allow a cable tie or metal wire to be inserted for fastening in order to strengthen the secondary locking and retaining force between the lever mechanism 2 and the first housing 1.

[0038] In some embodiments, the upper wall 12 of the first housing 1 is further provided with a locking portion 14, and the intermediate locking lever 22 abuts against the locking portion 14 so that the lever mechanism 2 remains in the locked position of the first housing 1. For example, when the lever mechanism 2 rotates to the locked position, the intermediate locking lever 22 is hooked onto the locking portion 14 to implement secondary locking of the lever mechanism 2.

[0039] Optionally, the locking portion 14 may be a boss, which is positioned on the upper wall 12 of the first housing 1 as a cantilever. That is, one side of the boss is connected to the upper wall 12 of the first housing 1, and the other side of the boss is positioned as a cantilever to form a free end. The boss has a transition surface 141 and a contact surface 142. The transition surface 141 extends from the upper wall 12 of the first housing 1 and has an arc-shaped upward slope to guide the rotation of the lever mechanism 2. The contact surface 142 is perpendicular to the upper wall 12 of the first housing 1. When the lever mechanism 2 rotates in a predetermined position, the intermediate locking lever 22 of the lever mechanism 2 comes into contact with the contact surface 142 of the locking portion 14 in order to lock the intermediate locking lever 22 with the contact surface 142 of the locking portion 14. While the lever mechanism 2 is rotating, the intermediate locking lever 22 penetrates the transition surface 141 and reaches the contact surface 142 so that the lever mechanism 2 remains in the locked position of the first housing 1.

[0040] In some embodiments, the upper wall 12 of the first housing 1 is further provided with an arc-shaped transition section 122, which is located on the axial rear side of the upper wall 12. That is, the arc-shaped transition section 122 is located on the side of the upper wall 12 away from the locking projection 212 in the locked position. In other words, in this disclosure, a portion of the upper wall 12 that is suitable for contacting the locking projection 212 so that the lever mechanism 2 remains in the locked position is located at the front of the upper wall 12, and the arc-shaped transition section 122 is located at the rear of the upper wall 12. By arranging the arc-shaped transition section 122, the lever mechanism 2 is guided so that it can smoothly rotate from the rear to the front in the locked position, and the operability of the connector 100 is also improved.

[0041] In some embodiments, the upper wall 12 of the first housing 1 is further provided with an inclined portion 121 and an arc-shaped transition portion 122, which are arranged sequentially on the axial rear side of the upper wall 12, i.e., on the side of the upper wall 12 adjacent to the locking recess 114. Specifically, when viewed forward along the axial rear end of the upper wall 12, two symmetrical inclined portions 121, two symmetrical arc-shaped transition portions 122, and two side edges are arranged sequentially on the side edges of the upper wall 12. That is, the arc-shaped transition portions 122 are located between the inclined portions 121 and the edges.

[0042] In a particular embodiment, a plastic member 3 is provided in the first housing 1 and is configured to accommodate a metal terminal. During assembly of the terminal and the wire of the connector 100, the rotating shaft bearing hole 215 of the lever mechanism 2 is mounted on the rotating shaft 112 of the first housing 1, and the locking projection 212 of the lever mechanism 2 is mounted on the locking recess 114 of the first housing 1. Fitting The lever mechanism 2 is locked in its primary locking position, and after the terminals and wires are assembled, the plastic member 3 is inserted into the first housing 1 from its side edge. The wires extend in the direction of the opening of the first housing 1, and the baffle 4 is inserted into the first housing 1 from bottom to top to close the plastic member 3. When the first housing 1 is aligned with the paired second housing 5, the toothed structure 216 located on the lever mechanism 2 aligns with the toothed structure of the paired second housing 5, and the lever mechanism 2 is rotated so that the toothed structure 216 drives the first housing 1 into the paired second housing 5 by the principle of leverage. When the intermediate locking lever 22 of the lever mechanism 2 is hooked onto the locking portion 14 located above the first housing 1, the first housing 1 is fully inserted into the paired second housing 5 in a predetermined position (as shown in Figure 7), and the secondary locking of the lever mechanism 2 is implemented. The second insertion hole 214 of the lever mechanism 2 is aligned with the first insertion hole 1 of the first housing 1 to insert a cable tie or metal wire for fastening, thereby increasing the secondary locking and retaining force between the lever mechanism 2 and the first housing 1.

[0043] A connector assembly 200 according to one embodiment of the present disclosure is described below. As shown in Figures 1 to 7, the connector assembly 200 includes a first housing 1, a second housing 5, and a lever mechanism 2. The lever mechanism 2 is rotatably connected to the first housing 1. The lever mechanism 2 includes two side levers 21 and an intermediate locking lever 22 connecting the two side levers 21, with locking projections 212 positioned on each of the two side levers 21. The first housing 1 includes two side walls 11, with locking recesses 114 corresponding to the locking projections 212 provided on each of the two side walls 11. The locking projections 212 and the locking recesses 114 are such that the lever mechanism 2 remains in a pre-locked position on the first housing 1. Fitting The first housing 1 further includes an upper wall 12, and in response to the first housing 1 being connected to the second housing 5, the locking projection 212 abuts against the upper wall 12 of the first housing 1 so as to keep the lever mechanism 2 locked in the first housing 1 and limit excessive rotation of the lever mechanism 2.

[0044] In the connector assembly 200 according to the embodiment of the present disclosure, locking projections 212 are arranged on each of the two lateral levers 21, and locking recesses 114 corresponding to the locking projections 212 are provided on each of the two side walls 11. The locking projections 212 are positioned such that the lever mechanism 2 remains in a pre-locked position on the first housing 1 and the locking recesses 114 Fitting In response to the connection of the first housing 1 to the second housing 5, the locking projection 212 abuts against the upper wall 12 of the first housing 1 to limit excessive rotation of the lever mechanism 2. The connector assembly 200 can be precisely positioned to keep the lever mechanism 2 locked in place in order to accurately align the insertion holes and improve the locking holding force of the connector assembly 200.

[0045] In this disclosure, the “up” direction can be understood as the side on which the upper wall 12 is located for the first housing 1, the “down” direction can be understood as the side of the first housing 1 facing the opposite direction from the upper wall 12, the “rear” direction can be understood as the side of the upper wall 12 closer to the locking recess 114, and the “front” direction can be understood as the side of the upper wall 12 away from the locking recess 114. The upper wall 12 may be found to have a front edge and a rear edge in the front-rear direction. The rear edge is located closer to the locking recess 114 than the front edge. When the locking projection 212 contacts the upper wall 12, the lever mechanism 2 can be prevented from rotating excessively in the direction closer to the front edge. That is, the lever mechanism 2 can be prevented from rotating excessively in the direction away from the locking recess 114.
