[0020] The present invention will be further described below with reference to the accompanying drawings and examples.

[0021] like Figures 1-6 As shown, this embodiment provides a power cable connector, including a detachably connectable male connector assembly 10, a female connector assembly 20, and an elastic element 30. The male connector assembly 10 is connected to cable A, and the female connector assembly 20 is connected to cable B, thereby enabling circuit continuity between cable A and cable B. After connection, the positive terminals of cable A and cable B are connected, and the negative terminals of cable A and cable B are connected. To more clearly illustrate the content of this utility model, the insertion direction of the male connector assembly 10 and the female connector 20 is defined as a first direction.

[0022] The male connector assembly 10 and the female connector assembly 20 are connected by a plug-in method to meet the need for quick connection of cables A and B. During installation, cable A is first connected to the male connector assembly 10, and cable B is connected to the female connector assembly 20. Then, the male connector assembly 10 is inserted into the female connector assembly 20. Specifically, the end of the female connector assembly 20 is provided with a main slot for the male connector assembly 10 to be inserted. After the male connector assembly 10 is inserted, it locks into place against the wall of the main slot, thus securing the two components. This method is existing technology in the field and will not be described in detail in this embodiment. A sealing gasket is also provided at the mating position of the male connector assembly 10 and the female connector assembly 20 to increase waterproof performance.

[0023] The male connector assembly 10 includes a male connector housing 11, a male connector terminal block 12, a plug-in portion 14, and a male connector guide piece 13.

[0024] The male connector housing 11 forms a first hollow channel with openings at both ends. The first hollow channel includes an inlet port 111 and a connection port 112 arranged opposite each other. Cable A is introduced through the inlet port 111, and the male connector terminal block 12 is assembled on the connection port 112. The inlet port 111 is a tensioning opening, which generates contraction capability by providing multiple notches. The tension of the inlet port 111 is adjusted by a nut. After the nut is screwed in, the inlet port 111 tightens inward to clamp cable A. The design of the tensioning opening is prior art in this embodiment and will not be described in detail here.

[0025] The male terminal block 12 is partially housed within the first hollow channel and partially exposed outside the first hollow channel. The exposed portion of the male terminal block 12 serves as a docking structure with the female connector assembly 20 and is inserted into the main slot on the female connector assembly 20.

[0026] The connector 14 is disposed at one end of the male connector 12 near the female connector assembly 20. The connector 14 includes a first connector 141, a second connector 142, and a third connector 143 disposed adjacent to each other. The male connector tab 13 includes a male positive connector tab 131 and a male negative connector tab 132. Both the second connector 142 and the third connector 143 have insertion holes formed inside. The male positive connector tab 131 is correspondingly encapsulated in the insertion hole of the second connector 142, and the male negative connector tab 132 is correspondingly encapsulated in the insertion hole of the third connector 143. The positive terminal of cable A is connected to the male positive connector tab 131, and the negative terminal is connected to the male negative connector tab 132.

[0027] The female connector assembly 20 includes a female connector housing 21, a female connector terminal block 22, a female connector guide piece 23, and a connector slot 24.

[0028] The female connector housing 21 forms a second hollow channel with openings at both ends. The female connector terminal block 22 is assembled at one end of the second hollow channel. The female connector guide piece 23 is mounted on the female connector terminal block 22 and fixed to the female connector terminal block 22. The female connector guide piece 23 includes a female connector positive electrode guide piece 231 and a female connector negative electrode guide piece 232. The positive electrode of cable B is connected to the female connector positive electrode guide piece 231, and the negative electrode is connected to the female connector negative electrode guide piece 232.

[0029] The insertion part 14 is inserted into the insertion slot 24 along a first direction. The insertion slot 24 is formed by the female head housing 21 and the female head terminal block 22. The insertion slot 24 includes a first insertion slot 241, a second insertion slot 242, and a third insertion slot 243 that communicate with each other. The first insertion part 141 is inserted into the first insertion slot 241, the second insertion part 142 is inserted into the second insertion slot 242, and the third insertion part 14... 3. The female connector positive electrode contact piece 231 is disposed in the second connector slot 242, and the female connector negative electrode contact piece 232 is disposed in the third connector slot 243. The female connector positive electrode contact piece 231 is inserted into the insertion hole of the second connector part 142 and connected to the male connector positive electrode contact piece 131. The female connector negative electrode contact piece 232 is inserted into the insertion hole of the third connector part 143 and connected to the male connector negative electrode contact piece 132.

[0030] The male connector 13 and the female connector 23 are connected to realize the circuit conduction function. Preferably, the male connector 13 is selected as a clip and the female connector 23 is selected as an insert. The female connector 23 is inserted between the two clips of the male connector 13. This method is a conventional technology in the field and will not be described in detail in this embodiment.

[0031] The elastic element 30 is housed within the insertion groove 24 and fixed to the female terminal block 22. It can be compressed along a first direction under the pressure of the insertion portion 14, thus buffering the impact force of the insertion portion 14. Specifically, the elastic element 30 is disposed within the first insertion groove 241 and can be compressed along a first direction under the pressure of the first insertion portion 141, thus buffering the impact force of the insertion portion 141. During a forceful docking operation, the first insertion portion 141 will compress the cantilever 32, causing the cantilever 32 to deform under pressure, generating a damping effect. This reduces the pushing speed and impact force of the first insertion portion 141 towards the female guide plate 23, preventing bending of the female guide plate 23 under forceful docking operations. Furthermore, the damping effect allows the user to better control the force during the docking operation, enabling the male connector assembly 10 to be pushed in smoothly and improving the accuracy of the docking between the male and female connector assemblies.

[0032] The elastic element 30 includes a base plate 31, a cantilever 32 disposed on the side of the base plate 31 near the male connector assembly 10, and a transition section 33 connecting the base plate 31 and the cantilever 32. The cantilever 32 is spaced apart from the base plate 31, and the transition section 33 provides a smooth transition.

[0033] There are two cantilever arms 32, located at opposite ends of the substrate 31, and each cantilever arm 32 is connected to the substrate 31 via a transition section 33. Preferably, the substrate 31, cantilever arms 32, and transition sections 33 are integrally formed, resulting in a stable structure.

[0034] The cantilever 32 is inclined relative to the substrate 31, and the relative angle between them is an acute angle. Compared with a parallel cantilever, this structure can increase the stroke range of the cantilever 32 and provide a damping effect by contacting the insertion part 14 earlier during the insertion process.

[0035] Furthermore, the ends of the first insertion portion 141, the second insertion portion 142, and the third insertion portion 143 are flush; the bottoms of the first insertion groove 241, the second insertion groove 242, and the third insertion groove 243 are flush; the extension height of the cantilever 32 relative to the bottom of the first insertion groove 241 is greater than the extension height of the female positive electrode contact piece 231 relative to the bottom of the second insertion groove 242, and greater than the extension height of the female negative electrode contact piece 232 relative to the bottom of the third insertion groove 243. This structural form ensures that during the docking process, the first insertion portion 141 contacts the cantilever first, effectively protecting the female positive electrode contact piece 231 and the female negative electrode contact piece 232.

[0036] The film 31 includes a first segment 311 and two second segments 312 located at both ends of the first segment 311. The second segments 312 are formed by bending and extending from the ends of the first segments 311 in a direction away from the male head assembly 10. The transition section 33 connects the second segments 312 and the cantilever 32.

[0037] The first segment 311 and the two second segments 312 cooperate to form a glue-containing groove 313, which is filled with adhesive. The substrate 31 is fixed to the female head assembly 20 by the adhesive. After the substrate 31 is fixed, the first segment 311 and the female head assembly 20 maintain a certain distance, so that the substrate 30 as a whole can obtain greater freedom and improve the effect of elasticity.

[0038] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
