[0027] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0029] See also Figure 1The embodiment of the utility model provides a jumper cable 100, which includes a plug 10, a pair of connecting wires 20 and two metal clips 30. The plug 10 can establish an electrical connection with the output interface of the starting power supply 200, and the two metal clips 30 are used to establish an electrical connection with the positive and negative electrodes of the power supply to be started (such as the battery on the car). Therefore, the starting power supply 200 can be electrically connected to the power supply to be started (such as the battery on the car) through the jumper cable 100, and then the engine starting circuit on the car can be electrically connected to the starting power supply 200. In this way, when the power of the power supply to be started (such as the battery on the car) is exhausted, the starting power supply 200 can provide the required electrical energy for the engine starting circuit on the car to start the car engine.
[0030] See also Figures 2 to 5 In one embodiment, the plug 10 includes a body 40 and a metal terminal 50. The body 40 includes a protrusion 42 that is higher than a top surface 41 of the body 40, and the protrusion 42 includes a first inclined surface 421 and a second inclined surface 422 that are inclined relative to the top surface 41, the first inclined surface 421 extends from top to bottom toward the top surface 41, and the second inclined surface 422 extends from top to bottom in a direction away from the top surface 41. The metal terminal 50 is fixed to the body 40.
[0031] refer to Figure 7 and Figure 8 With such a structure, when necessary, the user can use the thumb to contact the second inclined surface 422 to apply a pushing force to the plug 10, thereby inserting the plug 10 into the output interface of the starting power supply 200. When necessary, the user can use the thumb to contact the first inclined surface 421 to apply a pulling force to the plug 10, thereby pulling the plug 10 out of the output interface of the starting power supply 200.
[0032] The main body 40 is approximately a rectangular parallelepiped as a whole, and has a top surface 41 and a bottom surface 43 opposite to each other. The main body 40 also includes a contact surface 401, and an insertion portion 402 protrudes from the contact surface 401. The insertion portion 402 can be just inserted into the output interface of the starting power supply 200. At this time, the contact surface 401 conflicts with the starting power supply 200. The aforementioned "from top to bottom" refers to the vertical direction from the top surface 41 to the bottom surface 43.
[0033] refer to Figure 5In one embodiment, the first inclined surface 421 and the second inclined surface 422 meet to form a ridge 423. The first inclined surface 421 extends from the ridge 423 in the direction of the abutment surface 401 until it meets the top surface 41. The top surface 41 has a sufficient area so that it can contact most of the fingertip of the user's thumb. The top surface 41 and the first inclined surface 421 form a shallow pit so that most of the fingertip of the user's thumb can be placed in the pit. When the fingertip of the user's thumb is placed in the pit, the first inclined surface 421 contacts a small part of the fingertip of the user's thumb. Such contact allows a pulling force from the user to be applied to the main body 40, so that the user can pull the insertion portion 402 out of the output interface of the starting power supply 200.
[0034] In one embodiment, the second inclined surface 422 extends from the ridge 423 in a direction away from the contact surface 401 until it intersects with the tail end 403 of the body 40, and the tail end 403 is opposite to the contact surface 401. The area of the second inclined surface 422 is larger than that of the first inclined surface 421, so that a larger contact area can be provided, so that the fingertips of the user's thumb can comfortably contact the second inclined surface 422.
[0035] In one embodiment, the bottom surface 43 of the body 40 is flat. Figure 3 The main body 40 includes a protrusion 44 which is higher than the bottom surface 43, and the protrusion 44 includes a third inclined surface 441 and a fourth inclined surface 442 which are inclined relative to the bottom surface 43, and the third inclined surface 441 and the fourth inclined surface 442 meet to form a ridge 443. The third inclined surface 441 extends from the ridge 443 to the direction of the abutment surface 401 until it meets the bottom surface 43. The bottom surface 43 and the third inclined surface 441 form a shallow pit for accommodating a part of the side of the user's index finger. When the user's index finger is placed in the pit, the third inclined surface 441 contacts a small part of the side of the user's index finger. Such contact allows a pulling force from the user to be applied to the main body 40, so that the user can pull the insertion portion 402 out of the output interface of the starting power supply 200. That is to say, when the user wants to unplug the plug 10 connected to the starting power supply 200, the user puts one thumb into the pit formed by the top surface 41 and the first inclined surface 421, and puts one index finger into the pit formed by the bottom surface 43 and the third inclined surface 441, thereby allowing the user to pinch the main body 40, and exert a pulling force on the main body 40 through the contact between the thumb and the first inclined surface 421 and the contact between the index finger and the third inclined surface 441, thereby being able to unplug the plug 10 connected to the starting power supply 200.
[0036] In one embodiment, the fourth inclined surface 442 extends from the ridge 443 in a direction away from the abutment surface 401 until it intersects with the tail end 403 of the main body 40. The area of the fourth inclined surface 442 is larger than the area of the third inclined surface 441, so that a larger contact area can be provided, so that the index finger of the user can comfortably contact the fourth inclined surface 442. When the user wants to insert the plug 10 into the output interface of the starting power supply 200, the user contacts one of his thumbs with the second inclined surface 422 and one of his index fingers with the fourth inclined surface 442, so that the user can apply a thrust to the main body 40 through the second inclined surface 422 and the fourth inclined surface 442, and then the insertion portion 402 of the main body 40 can be inserted into the output interface of the starting power supply 200.
[0037] refer to Figure 5 , Figure 6 and Fig. 9 In one embodiment, the main body 40 includes a hollow shell 60 and a core 70 received in the shell 60, and the metal terminal 50 is fixed to the core 70. In one embodiment, the main body 40 also includes an auxiliary part 80, the auxiliary part 80 has a through hole 81 with two ends open, a first part 82 of the auxiliary part 80 is received in the shell 60, the core 70 includes a receiving cavity 71, a second part 83 of the auxiliary part 80 is received in the receiving cavity 71, and the metal terminal 50 is received in the through hole 81 of the auxiliary part 80.
[0038] In one embodiment, the housing 60 , the core 70 , the auxiliary portion 80 and the metal terminal 50 are fixed together by integral molding (eg, plastic injection molding).
[0039] In one embodiment, the housing 60 is a hollow structure with two ends open. Figure 6 The housing 60 has a first receiving cavity 61 and a second receiving cavity 62 which are connected to each other. The first receiving cavity 61 and the second receiving cavity 62 have bottom surfaces which are flush with each other and have different heights. Fig. 9 , corresponding to the structure of the first receiving cavity 61 and the second receiving cavity 62, the outer surface of the core 70 includes a first outer surface 72 and a second outer surface 73, the first outer surface 72 contacts the inner surface of the first receiving cavity 61, and the second outer surface 73 contacts the inner surface of the second receiving cavity 62. In this embodiment, the outer surface of the first portion 82 of the auxiliary portion 80 is opposite to and contacts the inner surface of the first receiving cavity 61, and the outer surface of the second portion 83 of the auxiliary portion 80 is opposite to and contacts the inner surface of the receiving cavity 71 of the core 70.
[0040] In one embodiment, reference Fig. 9The outer surface of the first portion 82 of the auxiliary portion 80 is provided with a first convex ring 821, and the inner surface of the housing 60 (i.e., the inner surface of the first receiving cavity 61) is provided with a first receiving groove 611 (see Figure 6 ), the first protruding ring 821 is received in the first receiving groove 611. By setting the first protruding ring 821 tightly clamped in the first receiving groove 611, the connection firmness between the auxiliary part 80 and the housing 60 can be increased.
[0041] In one embodiment, reference Fig. 9 The outer surface of the second portion 83 of the auxiliary portion 80 is provided with a second receiving groove 831, and the inner surface of the receiving cavity 71 of the core portion 70 is provided with a second convex ring 711 (see Figure 6 ), the second convex ring 711 is received in the second receiving groove 831. By arranging the second convex ring 711 to be tightly clamped in the second receiving groove 831, the connection firmness between the auxiliary part 80 and the core part 70 can be increased.
[0042] In one embodiment, reference Figure 5 The inner surface of the through hole 81 of the auxiliary part 80 is provided with a third protruding ring 811, and the outer surface of the metal terminal 50 is provided with a third receiving groove 51, and the third protruding ring 811 is received in the third receiving groove 51. By providing the third protruding ring 811 to be tightly clamped in the third receiving groove 51, the connection firmness between the metal terminal 50 and the auxiliary part 80 can be increased.
[0043] In one embodiment, the housing 60 is made of a flexible material, and the core 70 and the auxiliary part 80 are made of a hard material (e.g., hard plastic). In one embodiment, one end of the connecting wire 20 passes through the housing 60 and then extends into the core 70, and contacts a corresponding metal terminal 50. The core 70 is made of a hard material and can more firmly fix the metal terminal 50 and the connecting wire 20 connected to the metal terminal 50, so as to prevent the metal terminal 50 and the connecting wire 20 from being torsionally pulled off or having poor contact.
[0044] refer to Figure 4 and Figure 5 In one embodiment, the housing 60 includes a protective tube 63 at its rear end surrounding the connecting line 20. With such a structure, since the housing 60 is made of a flexible material, the protective tube 63 can be elastically deformed, allowing the connecting line 20 to swing within a certain angle range relative to the main body 40, thereby preventing the connecting line 20 from being damaged by excessive external force when swinging / twisting.
[0045] refer to Fig.10In one embodiment, the number of the metal terminals 50 is two. Accordingly, the auxiliary portion 80 includes two terminal receiving holes 84 and 85, and the two metal terminals 50 are received in the two terminal receiving holes 84 and 85. When the plug 10 is inserted into the output interface of the starting power supply 200, the two hollow terminals (not shown) in the output interface of the starting power supply 200 are received in the two terminal receiving holes 84 and 85, and the two metal terminals 50 are inserted into the two hollow terminals in the output interface of the starting power supply 200, thereby establishing an electrical connection. In order to prevent misinsertion, the two terminal receiving holes 84 and 85 have different shapes, one of the two terminal receiving holes 84 and 85 is circular, and the other is approximately square. Accordingly, the periphery of the two hollow terminals in the output interface of the starting power supply 200 is coated with a circular and approximately square coating layer. With such a structure, when a user attempts to insert the plug 10 into the output interface of the starting power supply 200 in a wrong direction, the plug 10 cannot be inserted into the output interface of the starting power supply 200 because the coating layers of the two hollow terminals in the output interface of the starting power supply 200 do not match the shapes of the two terminal receiving holes 84 and 85. With such a structure, it is possible to prevent the plug 10 from being inserted into the output interface of the starting power supply 200 in a wrong direction.
[0046] refer to Figure 5 In one embodiment, the metal terminal 50 includes a fixing portion 52 fixed to the main body 40 and a hollow metal tube 53 fixed to the fixing portion 52, and the hollow metal tube 53 is provided with a plurality of grooves 54 extending along its length direction (see Figure 2 ), the plurality of grooves 54 extend from the free end of the hollow metal tube 53 toward the fixing portion 52, so that the hollow metal tube 53 can be elastically deformed in the radial direction when being squeezed. With such a structure, when the two metal terminals 50 are inserted into the two hollow terminals in the output interface of the starting power supply 200, the hollow metal tube 53 is squeezed by the hollow terminals in the output interface of the starting power supply 200 and elastically deforms in the radial direction, so that the hollow metal tube 53 and the inner wall of the hollow terminal in the output interface of the starting power supply 200 are always kept in close contact, thereby avoiding poor contact caused by long-term use.
[0047] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present utility model.
