Description

Technical Field

[0001] This utility model relates to the field of electrical connections, and more specifically, to a connector. Background Technology

[0002] With the rapid development of new energy vehicles, the demand for high-voltage connectors is also increasing. During transportation and use, if the CPA is not locked, the rocker arm may be opened even with a small force when it is locked to the connector housing.

[0003] Therefore, there is an urgent need to design a new connector structure to solve the above problems. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for connectors to address the problem that rocker arms are at risk of opening under relatively small forces during connector transportation and use.

[0005] According to a first aspect of the present invention, a connector is provided for mating with a mating connector, comprising a housing and a rocker arm, the rocker arm being pivotally connected to the housing and rotatable from a pre-installed position to a locked position, the rocker arm comprising a crossbeam and rocker arms symmetrically arranged at both ends of the crossbeam, the housing having a rotating shaft, the rocker arms having a pivot hole cooperating with the rotating shaft, the rotating shaft having a radially protruding protrusion, and the pivot hole having a pressing structure cooperating with the protrusion, when the rocker arm rotates from the pre-installed position to the locked position, the protrusion and the pressing structure interact to drive the rocker arm toward the housing and press it in place.

[0006] Optionally, at least one of the housing and the rocker arm is provided with a damping structure. When the rocker arm is in the locked position, the damping structure frictionally engages with the other to prevent the rocker arm from rotating.

[0007] Optionally, the damping structure is a friction damping element provided on the side wall of the housing and / or the inner surface of the rocker arm.

[0008] Optionally, the friction damping element is an elastic rubber sheet or a coated material provided on the side wall of the housing and / or the inner surface of the rocker arm.

[0009] Optionally, the damping structure is an integrally formed textured feature provided on the sidewall of the housing and / or the inner surface of the rocker arm.

[0010] Optionally, there are two protrusions symmetrically arranged at the end of the rotating shaft, and the extrusion structure is a stop block inside the pivot hole. The stop blocks are symmetrically arranged on the inner wall of the pivot hole, and a channel for the protrusions to pass through is formed between the two stop blocks.

[0011] Optionally, the surface on which the stop and the protrusion mate is a helical surface;

[0012] When the rocker arm is rotated from the pre-installed position to the locked position, the protrusion slides along the helical surface, causing the rocker arm to produce an axial displacement toward the housing.

[0013] Optionally, a pre-locking mechanism and a final locking mechanism are further provided between the housing and the rocker arm, and the rocker arm is limited to the pre-installed position and the locked position by the pre-locking mechanism and the final locking mechanism; the damping structure is provided on the side close to the final locking mechanism.

[0014] Optionally, the pre-locking mechanism consists of a pre-locking buckle protruding from the outer wall of the housing and a pre-locking slot on the rocker arm. The pre-locking buckle and the pre-locking slot engage to limit the rocker arm to the pre-installed position.

[0015] Optionally, the final locking mechanism consists of a final locking buckle protruding from the outer wall of the housing and a final locking groove on the rocker arm. The final locking buckle and the final locking groove engage to limit the rocker arm to the locked position.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention features a protrusion on the pivot of the connector housing and a pressing structure that mates with the protrusion within the pivot hole of the rocker arm. When the rocker arm rotates from the pre-installed position to the locked position, the protrusion and the pressing structure interact, driving the rocker arm to move toward the housing and press it in place, thus achieving the clamping function between the rocker arm and the housing. This avoids the risk of the rocker arm being opened during transportation and use due to the lack of locking CPA, where the rocker arm is subjected to a small force when locked to the connector housing.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] According to the first aspect of this utility model, as Figures 1-3 As shown, a connector is provided for mating with a mating connector 30, including a housing 10 and a rocker arm 20. The rocker arm 20 is pivotally connected to the housing 10 and can rotate from a pre-installed position to a locked position. The rocker arm 20 includes a crossbeam 21 and rocker arms 22 symmetrically arranged at both ends of the crossbeam 21. The housing 10 is provided with a rotating shaft 11. The rocker arm 22 is provided with a pivot hole 221 that mates with the rotating shaft 11. The rotating shaft 11 is provided with a radially protruding protrusion 111. The pivot hole 221 is provided with a pressing structure that mates with the protrusion 111. When the rocker arm 20 rotates from the pre-installed position to the locked position, the protrusion 111 interacts with the pressing structure, driving the rocker arm 22 to move toward the housing 10 and press it.

[0031] With the rapid development of new energy vehicles, the demand for high-voltage connectors is also increasing. During transportation and use, if the CPA is not locked, the rocker arm 20 may be opened even with a small force when it is locked to the connector housing 10.

[0032] This invention provides a protrusion 111 on the rotating shaft 11 of the connector housing 10, and a pressing structure that cooperates with the protrusion 111 is provided in the pivot hole 221 of the rocker arm 22. When the rocker arm 20 rotates from the pre-installed position to the locked position, the protrusion 111 interacts with the pressing structure, driving the rocker arm 22 to move toward the housing 10 and press it, thereby realizing the clamping function of the rocker arm 20 and the housing 10. This avoids the risk that the rocker arm 20 will be opened during transportation and use due to the lack of locking CPA, when it is locked with the connector housing 10 and subjected to a small force.

[0033] In some embodiments, at least one of the housing 10 and the rocker arm 22 is provided with a damping structure. When the rocker arm 20 is in the locked position, the damping structure frictionally engages with the other to prevent the rocker arm 20 from rotating.

[0034] In some embodiments, such as Figure 1 As shown, the damping structure is a friction damping element 12 provided on the side wall of the housing 10 and / or the inner surface of the rocker arm 22.

[0035] The damping structure can be configured in the following ways: one is to provide friction damping elements 12 on the side wall of the housing 10 and the inner surface of the rocker arm 22 respectively. When the rocker arm 20 is in the locked position, the friction damping elements 12 on both are in frictional engagement to prevent the rocker arm 20 from rotating; another is to provide friction damping elements 12 on the side wall of the housing 10. When the rocker arm 20 is in the locked position, the inner surface of the rocker arm 22 is in frictional engagement with the friction damping elements 12 on the housing 10 to prevent the rocker arm 20 from rotating; yet another is to provide friction damping elements 12 on the inner surface of the rocker arm 22. When the rocker arm 20 is in the locked position, the friction damping elements 12 on the inner surface of the rocker arm 22 are in frictional engagement with the side wall of the housing 10 to prevent the rocker arm 20 from rotating.

[0036] In some embodiments, such as Figure 1 As shown, the friction damping element 12 is an elastic rubber sheet or a coated material provided on the side wall of the housing 10 and / or the inner surface of the rocker arm 22.

[0037] Providing a rubber sheet or coating with a damping-enhancing paint on the side wall of the housing 10 and / or the inner surface of the rocker arm 22 can cause the inner surface of the rocker arm 22 to rub against the outer wall of the housing 10 when the rocker arm 20 is in the locked position, thereby preventing the rocker arm 20 from rotating.

[0038] In some embodiments, such as Figure 1As shown, the damping structure is an integrally formed textured feature provided on the side wall of the housing 10 and / or the inner surface of the rocker arm 22.

[0039] An integrally formed textured feature is provided on the side wall of the housing 10 and / or the inner surface of the rocker arm 22. The textured feature is simple and easy to manufacture. When the rocker arm 20 is in the locked position, the inner surface of the rocker arm 22 can be frictionally engaged with the outer wall of the housing 10 to prevent the rocker arm 20 from rotating.

[0040] In some embodiments, such as Figures 1-3 As shown, there are two protrusions 111, which are symmetrically arranged at the end of the rotating shaft 11. The extrusion structure is a stop 222 in the pivot hole 221. The stop 222 is symmetrically arranged on the inner wall of the pivot hole 221. A channel 223 is formed between the two stop 222 for the protrusions 111 to pass through.

[0041] The protrusion 111 is inserted into the pivot hole 221 via the channel 223 along with the pivot 11. As the rocker arm 20 rotates from the pre-installed position to the locked position, the protrusion 111 interacts with the pressing structure, driving the rocker arm 22 toward the housing 10 and pressing it.

[0042] In some embodiments, such as Figures 1-4 As shown, the surface of the stop 222 that mates with the protrusion 111 is a helical surface 2221; when the rocker arm 20 rotates from the pre-installed position to the locked position, the protrusion 111 slides along the helical surface 2221, causing the rocker arm 22 to produce an axial displacement toward the housing 10.

[0043] The helical surface 2221 provides a sliding trajectory for the protrusion 111 and has a guiding function. The protrusion 111 slides along the helical surface 2221. The helical surface 2221 has a low point a and a high point b relative to the outer wall of the housing 10 in the axial direction of the pivot hole 221. When the rocker arm 20 is in the pre-installed position, the protrusion 111 first contacts the low point a. When it is in the locked position, the protrusion 111 contacts the high point b. The distance D1 from the low point a to the inner surface of the rocker arm 22 is less than the distance D2 from the high point b to the inner surface of the rocker arm 22. During the process of the rocker arm 20 rotating from the pre-installed position to the locked position, it slides from the low point a to the high point b along the helical surface 2221, which can drive the rocker arm 22 to generate an axial displacement towards the housing 10, thereby achieving the clamping of the rocker arm 20 and the housing 10. This avoids the risk that the rocker arm 20 will be opened during transportation and use due to the lack of locking CPA when it is locked with the connector housing 10 and subjected to a small force.

[0044] In some embodiments, such as Figures 1-3 As shown, a pre-locking mechanism and a final locking mechanism are also provided between the housing 10 and the rocker arm 22. The rocker arm 22 is limited to the pre-installed position and the locked position by the pre-locking mechanism and the final locking mechanism; the damping structure is provided on the side close to the final locking mechanism.

[0045] The damping structure is located near the final locking mechanism. By clamping the inner surface of the rocker arm 22 with the side wall of the housing 10 on the locking mechanism side, it increases the friction between the two, thereby securing the rocker arm 20 in the locked position and preventing the rocker arm 20 from being accidentally opened.

[0046] In some embodiments, such as Figures 1-2 As shown, the pre-locking mechanism consists of a pre-locking buckle 13 protruding from the outer wall of the housing 10 and a pre-locking slot 224 opened on the rocker arm 22. The pre-locking buckle 13 and the pre-locking slot 224 engage to limit the rocker arm 20 to the pre-installed position.

[0047] In some embodiments, such as Figure 3 As shown, the final locking mechanism consists of a final locking buckle 14 protruding from the outer wall of the housing 10 and a final locking groove 225 opened on the rocker arm 22. The final locking buckle 14 and the final locking groove 225 engage to limit the rocker arm 20 to the locked position.

[0048] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
