[0041] Referring to Figures 1-4 , an embodiment of the wire insertion terminal of the present application.

[0042] The wire insertion terminal includes a male terminal 100 and a female terminal 200.

[0043] The male terminal 100 includes a male terminal housing 110, one end of the male terminal housing 110 is provided with a plug portion 111, and the other end is connected to a wire harness 400. The plug portion 111 can be designed in various shapes, such as a circle, a rectangle, etc., to adapt to different insertion requirements.

[0044] The female terminal 200 comprises a female terminal housing 210, one end of the female terminal housing 210 is provided with a slot 211, and the other end is connected with a wire harness 400. When the plug part 111 is inserted into the slot 211, the male terminal 100 and the female terminal 200 are fixed through the clamping structure. The shape of the slot 211 should match the plug part 111 to ensure the reliability of the insertion.

[0045] The rib structure 216 is arranged on the male terminal housing 110 or the female terminal housing 210, and is located outside the clamping structure to prevent the clamping structure from being extruded by external force and causing the clamping structure to loosen.

[0046] The rib structure 216 can be designed to be integrally formed with the male terminal housing 110 or the female terminal housing 210, which not only reduces the manufacturing cost, but also improves the overall strength of the structure.

[0047] The wire insertion terminal described above provides additional protection for the clamping structure through the rib structure 216, effectively preventing the clamping structure from being extruded by external force and causing the clamping structure to loosen, and improving the reliability of the connection. Even if multiple wires are bundled together or are extruded by other components, the rib structure 216 can effectively protect the clamping structure and prevent it from loosening, thereby avoiding poor contact or open circuit conditions and ensuring the normal operation of the washing machine and improving safety.

[0048] In some embodiments of the present application, the clamping structure comprises a locking arm 112 and a clamping groove 213. The locking arm 112 is arranged on the male terminal housing 110, and the locking arm 112 is provided with a clamping jaw 1123. The locking arm 112 can be designed in various shapes, such as cantilever type, elastic arm, etc., as long as it can realize the clamping function.

[0049] The clamping groove 213 is correspondingly arranged on the female terminal housing 210, and when the plug part 111 is inserted into the slot 211, the clamping jaw 1123 is clamped with the clamping groove 213. The shape of the clamping groove 213 should match the clamping jaw 1123 to ensure the reliability of the clamping.

[0050] The clamping structure realizes the reliable fixation between the male terminal 100 and the female terminal 200 through the cooperation of the locking arm 112 and the clamping groove 213. When the plug part 111 is inserted into the slot 211, the clamping jaw 1123 is clamped with the clamping groove 213 to form a lock to prevent the male terminal 100 and the female terminal 200 from loosening. This structure is simple and reliable, easy to implement, and has good anti-vibration performance.

[0051] In other embodiments, the positions of the locking arm 112 and the clamping groove 213 can be interchanged, i.e. the locking arm 112 is arranged on the female terminal housing 210, and the clamping groove 213 is arranged on the male terminal housing 110.

[0052] In some embodiments of the present application, the specific structure of the locking arm 112 and the clamping groove 213 is further limited.

[0053] The locking arm 112 includes a base portion 1121, a cantilever portion 1122, and a clamping jaw 1123 provided at the front end of the cantilever portion 1122. The base portion 1121 is used to fix the locking arm 112 on the male end shell 110, the cantilever portion 1122 has elasticity, and the clamping jaw 1123 is used to clamp with the clamping groove 213.

[0054] The clamping groove 213 is provided on the female end shell 210, and a limiting portion 214 cooperating with the clamping jaw 1123 is provided on the inner side wall of the clamping groove 213, and the limiting portion 214 and the clamping jaw 1123 form a locking fit. The limiting portion 214 can be designed in various shapes, such as a protrusion, a step, etc., as long as it can cooperate with the clamping jaw 1123 to achieve locking.

[0055] By pressing the cantilever portion 1122, the clamping jaw 1123 is elastically deformed towards the base portion 1121 and disengaged from the limiting portion 214, thereby enabling the clamping groove 213 to be withdrawn, and the unlocking of the clamping structure is achieved.

[0056] In the natural state, the cantilever portion 1122, the clamping jaw 1123 and the limiting portion 214 are in a locked state to limit the axial movement of the wire insertion terminal.

[0057] The above-mentioned locking arm 112 and clamping groove 213 structure design is reasonable, which realizes the quick locking and unlocking of the wire insertion terminal. By pressing the cantilever portion 1122, the locking can be easily unlocked, which is convenient for users to maintain and replace. At the same time, in the natural state, the clamping jaw 1123 and the limiting portion 214 are in a locked state, which ensures the reliability of the connection.

[0058] In some embodiments of the present application, a protruding rib 1124 is provided on the outer side of the cantilever portion 1122. The setting of the protruding rib 1124 improves the bending strength of the cantilever portion 1122, preventing it from deforming or breaking after being pressed multiple times. At the same time, the protruding rib 1124 provides a better pressing feeling, making the user more comfortable when unlocking.

[0059] The protruding rib 1124 can be designed to be integrally formed with the cantilever portion 1122, which simplifies the manufacturing process and improves the overall structure. The shape and number of the protruding rib 1124 can be optimized according to actual needs, such as using a straight line or a wave shape design, to further improve the strength and pressing feeling. In addition, the surface of the protruding rib 1124 can be provided with anti-slip texture to enhance the friction force when pressing.

[0060] In some embodiments of the present application, the first inclined surface a is provided on the front end of the clamping jaw 1123 away from the base portion 1121, and the second inclined surface b is provided on the limiting portion 214 to cooperate with the first inclined surface a. When the clamping jaw 1123 is inserted into the clamping groove 213, the first inclined surface a and the second inclined surface b are in contact and slide relative to each other, so that the clamping jaw 1123 is elastically deformed towards the base portion 1121 until it returns to the natural state after passing the limiting portion 214 and forms a locking fit with the limiting portion 214, thereby achieving axial fixation of the wire insertion terminal. Through the guiding effect of the inclined surface, the clamping jaw 1123 can be smoothly inserted into the clamping groove 213 and automatically locked, so that the installation of the insertion terminal is faster and more accurate.

[0061] In some embodiments of the present application, the specific structure of the clamping groove 213 is as shown in Figure 4 The vertical rib portion 212 can play a guiding and supporting role to ensure that the clamping jaw 1123 can accurately cooperate with the limiting portion 214. At the same time, the provision of the vertical rib portion 212 also enhances the overall strength of the female end housing 210 to prevent deformation during plugging.

[0062] In some embodiments of the present application, a limiting boss 215 is further provided between the two vertical rib portions 212, and the clamping jaw 1123 abuts against the limiting boss 215 after being clamped in the clamping groove 213. The abutment of the limiting boss 215 and the clamping jaw 1123 provides additional fixing force, which can further limit the movement of the clamping jaw 1123 and prevent the insertion terminal from loosening under the action of vibration or external force, thereby improving the reliability of the locking. The height and shape of the limiting boss 215 can be optimized according to actual needs. The height of the limiting boss 215 is lower than the height of the clamping jaw 1123, which facilitates pressing the clamping jaw 1123 to achieve unlocking.

[0063] In some embodiments of the present application, the blocking rib structure 216 is provided on the female end housing 210 and located outside the limiting portion 214, which is used to prevent the clamping jaw 1123 from being squeezed and loosened by external force after cooperating with the limiting portion 214.

[0064] The blocking rib structure 216 can be designed to be integrally formed with the female end housing 210, which not only reduces the manufacturing cost but also improves the overall structure. The height and thickness of the blocking rib structure 216 can be optimized according to actual needs to balance the protection effect and space utilization.

[0065] In some embodiments of the present application, as shown in Figure 4As shown, the blocking rib structure 216 includes two wing plate parts 2161 and a blocking plate part 2162. The two wing plate parts 2161 are respectively located on both sides of the clamping groove 213. The wing plate parts 2161 can play a supporting and protecting role to prevent the clamping groove 213 from being extruded and deformed.

[0066] The blocking plate part 2162 is connected with the top ends of the two wing plate parts 2161. The blocking plate part 2162 can play an isolation role to prevent external objects from contacting the clamping structure.

[0067] The combination of the wing plate parts 2161 and the blocking plate part 2162 provides all-round protection to prevent the clamping structure from being extruded by external force in any direction, which can effectively prevent the clamping structure from being loosened due to extrusion by external force. At the same time, the overall design of the blocking rib structure 216 improves the strength of the female end shell 210 to prevent it from being deformed during plugging. The shapes of the wing plate parts 2161 and the blocking plate part 2162 can be optimized according to actual needs. For example, the wing plate parts 2161 can be designed as trapezoidal to improve the structural strength; and the blocking plate part 2162 can be designed as a straight plate.
