Description

Technical Field

[0001] This utility model belongs to the field of junction box technology and relates to a quick-connect structure for a motor junction box. Background Technology

[0002] The junction box on the water pump motor is usually exposed and connected to the external power line through a connector to supply power to the water pump. The junction box is usually installed on the water pump motor and connected to the external power line through a connector. However, for ease of installation, the junction box and connector are exposed. To ensure the sealing effect of the connection, a relatively stable connection method is usually used.

[0003] For example, Chinese patent application [Authorization Announcement No.: CN118920173B] discloses a high-voltage waterproof power connector for new energy vehicles, including a first connector and a second connector that is plugged into the first connector. The first connector includes a first housing, and the outer wall of the first housing is provided with a snap-fit ​​element. The second connector includes an outer shell, and the inner side of the outer shell is provided with an elastic snap-fit ​​lever. The free end of the snap-fit ​​lever is provided with a snap-fit ​​element for receiving the snap-fit ​​element. The snap-fit ​​element of the first housing enters the limiting hole through a first mounting channel and is locked into the outer shell. The second connector also includes a locking element, one end of which is provided with a protruding limiting part and a locking part. The locking part is partially received in the limiting hole and abuts against the snap-fit ​​lever, thus restricting its movement.

[0004] The above structure involves inserting the snap-fit ​​component of the first housing into the limiting hole and locking it with the outer housing. The locking component then fixes and limits the outer housing to the first housing, thereby achieving a stable connection between the first connector and the second connector. In the use of existing motors, such as water pump motors, the motors need to be moved frequently depending on their location. Therefore, it is necessary not only to consider the connection stability of the first and second connectors, but also to ensure that quick insertion is possible. Although the locking component used in the above structure improves stability, it also increases the difficulty of insertion and reduces the ease of assembly. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a quick-connect structure for a motor junction box. The technical problem to be solved by this utility model is: how to solve the problem of low ease of assembly of the existing motor junction box connection structure while ensuring stability and safety.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A quick-connect structure for a motor junction box includes a box body with a protrusion forming a plug-in portion. The plug-in portion has a plug-in groove. The quick-connect structure includes a connector that can be partially embedded in the plug-in groove and is electrically connected to the motor junction box. The connector is characterized by having an elastic latch and a locking plate located below the elastic latch. The plug-in portion has a clearance groove for the locking plate to slide against it. The groove wall of the clearance groove protrudes to form a locking block. The elastic latch has a locking hole for the locking block to engage.

[0008] The junction box and the connector are connected by a plug-in joint. The connector is inserted into the plug-in slot, at which point it is electrically connected to the motor junction box. During the plug-in process, the elastic latch and the locking plate move synchronously toward the plug-in part of the junction box. The locking plate slides along the wall of the clearance groove, thus positioning the connector for plug-in. The locking block on the clearance groove lifts the elastic latch as it moves toward the plug-in part, and moves until the locking block is inserted into the locking hole of the elastic latch, thus achieving locking and positioning. The cooperation of the elastic latch and the locking block achieves the positioning of the junction box and the connector. The clearance groove and the locking plate improve the stability of the locking. Furthermore, the locking plate ensures that the connector can only be plugged into the motor junction box when the plug-in direction is correct, i.e., when the locking plate is directly opposite the clearance groove, thus avoiding reverse insertion, improving safety and ease of assembly.

[0009] In the above-mentioned quick-connect structure of the motor junction box, the locking block has an inclined locking wall, the elastic latch has a guide block, the guide block has an inclined guide wall, and when the elastic latch slides toward the box body, the guide wall can slide along the locking wall and push the elastic latch upward.

[0010] The guide block design allows the elastic latch to be stably pushed upwards during engagement, facilitating the insertion of the locking block into the locking hole of the elastic latch, thus improving engagement efficiency and increasing ease of assembly.

[0011] In the aforementioned quick-connect structure of the motor junction box, the card plate has an elongated slot, the card block can be located in the slot, and the outer wall of the card plate fits against the wall of the clearance slot.

[0012] The slotted opening of the card plate ensures that it will not come into contact with the card block during the snap-fit ​​process, thus guaranteeing that the card plate only engages with the wall of the clearance slot to achieve guidance and positioning.

[0013] In the quick-connect structure of the motor junction box described above, the guide block portion is located within the opening slot.

[0014] This structure allows for a larger guide block thickness, resulting in smoother lifting of the elastic latch without affecting the sliding of the latch plate.

[0015] In the quick-connect structure of the motor junction box described above, the plug part has an abutment ring, the outer end wall of the plug has an abutment wall, the abutment wall presses against the abutment ring, and the groove of the clearance groove disconnects the abutment ring.

[0016] This design ensures that the motor junction box and the connector can stably abut each other after insertion, improving installation stability.

[0017] Compared with existing technologies, the quick-connect structure of this motor junction box has the following advantages: the locking plate slides along the wall of the clearance groove to position the connector for insertion. Furthermore, the locking block on the clearance groove allows the elastic latch to move towards the insertion part, lifting it upwards and moving it until it engages with the latching hole of the elastic latch, thus achieving locking and positioning. The cooperation between the elastic latch and the locking block ensures the positioning of the box body and the connector. The clearance groove and locking plate enhance the stability of the locking mechanism. The locking plate ensures that the connector can only be inserted into the motor junction box when the insertion direction is accurate, i.e., when the locking plate is directly opposite the clearance groove, preventing reverse insertion and improving safety and ease of assembly.

Detailed Implementation

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1 and Figure 2As shown, the quick-connect structure of this motor junction box includes a box body 1, a protrusion forming a plug-in part 11 on the box body 1, a plug-in groove 12 on the plug-in part 11, and a plug connector 2. The quick-connect structure includes a plug connector 2, which can be partially embedded in the plug-in groove 12 and is electrically connected to the motor junction box.

[0024] Specifically, such as Figure 1-3 As shown, the connector 2 is provided with an elastic latch 21 and a locking plate 22 located below the elastic latch 21. The connector 11 is provided with a relief groove 13 for the locking plate 22 to slide against it. The groove wall of the relief groove 13 protrudes to form a locking block 14. The elastic latch 21 is provided with a locking hole 21a for the locking block 14 to be inserted into.

[0025] The housing 1 and the connector 2 are connected by a plug-in joint. The connector 2 is partially embedded into the plug-in slot 12, at which point the connector 2 is electrically connected to the motor junction box. During the plug-in process, the elastic latch 21 and the locking plate 22 move synchronously toward the plug-in portion 11 of the housing 1. The locking plate 22 slides along the wall of the clearance groove 13, thus positioning the connector 2 for plug-in. Furthermore, the locking block 14 on the clearance groove 13 causes the elastic latch 21 to move toward the plug-in portion 11, lifting it upwards and moving it to the locking position. Block 14 is embedded into the snap-fit ​​hole 21a of the elastic snap-fit ​​tongue 21 to achieve snap-fit ​​positioning of the two. Through the cooperation of the elastic snap-fit ​​tongue 21 and the snap-fit ​​block 14, the positioning of the box body 1 and the plug 2 is achieved. The setting of the clearance groove 13 and the snap-fit ​​plate 22 improves the stability of the snap-fit ​​between the two. Furthermore, the setting of the snap-fit ​​plate 22 ensures that the plug 2 can only be inserted into the motor junction box when the insertion direction is accurate, that is, when the snap-fit ​​plate 22 is directly facing the clearance groove 13, thus avoiding the situation of reverse insertion and improving the safety of use and the convenience of assembly.

[0026] like Figure 2 and Figure 3 As shown, the latch 14 has an inclined latching wall 14a, the elastic latch 21 has a guide block 21b, and the guide block 21b has an inclined guide wall 21c. When the elastic latch 21 slides toward the box 1, the guide wall 21c can slide along the latching wall 14a and push the elastic latch 21 upward. The latch plate 22 has an elongated slot 22a. The latch 14 can be located in the slot 22a, and the outer wall of the latch plate 22 is in contact with the groove wall of the clearance groove 13. The guide block 21b is partially located in the slot 22a.

[0027] like Figure 1-3 As shown, the plug portion 11 has an abutment ring 15, and the outer end wall of the plug 2 has an annular abutment wall 23. The abutment wall 23 presses against the abutment ring 15, and the groove of the clearance groove 13 disconnects the abutment ring 15.

[0028] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
