Description

Technical Field

[0002] Automotive connectors generally include a sheath and a terminal. The terminal is crimped onto the wire and used to connect the vehicle's electrical equipment components. The sheath has a shell and a number of cavities that are arranged together and close to each other, and the cavities accommodate the terminals respectively; the cavities of the sheath are generally provided with elastically deformable spring tongues, which lock the terminals by locking the protruding parts on the terminals, thereby firmly fixing the terminals in the sheath and preventing them from being pulled out of the shell. Usually, the connector can also be provided with a secondary locking device, which can further keep the terminals firmly in the sheath even if there is a pulling force on the cables connected to each terminal.

[0050] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0051] See also Figures 1 to 7 The connector terminal 10 provided by an embodiment of the present invention comprises a plug-in portion 1, wherein the plug-in portion 1 comprises a main body portion 11 and an elastic portion 12, wherein the main body portion 11 has a plug-in passage 110 for plugging and mating with a male terminal 20 of the connector, and the elastic portion 12 is located in the plug-in passage 110. The main body portion 11 has a first wall 111 and a second wall 112 disposed opposite to each other.

[0052] The elastic portion 12 includes an elastic contact segment 121, a first elastic support segment 122 and a second elastic support segment 123. The first end of the elastic contact segment 121 is connected to the first wall 111, and the second end of the elastic contact segment 121 extends in a direction away from the first end of the elastic contact segment 121 and the first wall 111. The first end of the first elastic support segment 122 is connected to the second end of the elastic contact segment 121, and the second end of the first elastic support segment 122 extends in a direction toward the first wall 111 and the first end of the elastic contact segment 121. The first end of the second elastic support segment 123 is connected to the second end of the first elastic support segment 122, and the second end of the second elastic support segment 123 extends in a direction away from the first wall 111 and the second end of the first elastic support segment 122.

[0053] When the male terminal 20 of the connector is inserted into the insertion channel 110, the elastic part 12 rotates toward the first wall 111 of the main body 11, the middle part of the first and second ends of the first elastic support segment 122 abuts against the first area A of the first wall 111 of the main body 11, the second end of the first elastic support segment 122 abuts against the second area B of the first wall 111 of the main body 11, and the second end of the second elastic support segment 123 abuts against the third area C of the elastic contact segment 121, so that the elastic part 12 provides a clamping force (positive force) that can clamp the male terminal 20 between the elastic contact segment 121 and the second wall 112 of the main body 11. The male terminal 20 forms an electrical connection with the connector terminal 10.

[0054] In the connector terminal of the embodiment of the present invention, when the male terminal 20 of the connector is inserted into the insertion channel 110, the elastic portion 12 rotates toward the first wall 111 of the main body 11, the elastic contact section 121 and the second wall 112 of the main body 111 clamp the male terminal 20, the middle portion of the first elastic support section 122 abuts against the first area A of the first wall 111 of the main body 111, the middle portion of the first elastic support section 122 generates elastic deformation at the first area A and is subjected to a force F1 toward the second wall 112 of the main body 11 and perpendicular to the insertion direction of the male terminal 20, and the first elastic support section 122 is elastically deformed at the first area A. The second end of the support section 122 abuts against the second area B of the first wall 111 of the main body 11, and the second end of the first elastic support section 122 generates elastic deformation at the second area B and is subjected to a force F2 toward the second wall 112 of the main body 11 and perpendicular to the plug-in direction of the male terminal 20. Since the second end of the second elastic support section 123 abuts against the third area C of the elastic contact section 121, the component force F21 of the force F2 along the extension direction of the second elastic support section generates a force F211 toward the second wall 112 of the main body 11 and perpendicular to the plug-in direction of the male terminal 20 at the third area C. In this way, compared with the prior art, the elastic portion 12 can provide a greater positive force (clamping force for clamping the male terminal 20). That is, the connector terminal of the present application can provide a greater positive force at the same volume as the existing terminal or a smaller volume. While meeting the miniaturization of the terminal, the higher requirements for connection reliability between the connector terminal and the male terminal are met.

[0055] In addition, the second end of the second elastic support segment 123 abuts against the third area C of the elastic contact segment 121, which causes the elastic contact segment 121 to rotate around the third area C as a fulcrum, reducing the elastic force arm of the elastic contact segment 121 and enabling the elastic portion 12 to generate a larger positive force.

[0056] In one embodiment, the elastic portion 12 further includes a support and blocking wall 124, which is connected to the middle of the elastic contact segment 121 and extends in a direction close to the first wall 111 of the main body 11, and the second end of the second elastic support segment 123 faces the support and blocking wall 124; when the male terminal 20 of the connector is inserted into the plug channel 110, the second end of the second elastic support segment 123 abuts against the fourth area D of the support and blocking wall 124. In this way, the deformation displacement of the second elastic support segment 123 can be limited to prevent the second elastic support segment 123 from being deformed too much.

[0057] The first area A may be a point, a line, or a surface, that is, the middle portion of the first elastic support segment 122 may be in point contact, line contact, or surface contact with the first wall 111 of the main body 11 .

[0058] The second region B may be a point, a line, or a surface, that is, the second end of the first elastic support segment 122 may be in point contact, line contact, or surface contact with the first wall 111 of the main body 11 .

[0059] The third region C may be a point, a line, or a surface, that is, the second elastic supporting segment 123 and the elastic contact segment 121 may be in point contact, line contact, or surface contact.

[0060] The fourth area D may be a point, a line, or a surface, that is, the second elastic supporting segment 123 and the supporting blocking wall 124 may be in point contact, line contact, or surface contact.

[0061] In one embodiment, see Figure 7 A through hole 1211 is provided in the middle of the elastic contact section 121, and the second end of the second elastic support section 123 is located on a side of the through hole 121 close to the first wall 111 of the main body 11, and the second end of the second elastic support section 123 spans the through hole 1211 (i.e., the width of the second elastic support section 123 is greater than the width of the through hole 1211), so that when the male terminal 20 of the connector is inserted into the plug channel 110, the second end of the second elastic support section 123 contacts the wall surface of the elastic contact section 121 located around the through hole 1211. The support blocking wall 124 is bent from the side edge of the through hole 1211 away from the crimping portion 2 toward the first wall 111 of the main body 11, and passes through the through hole 1211.

[0062] In one embodiment, see Figure 3 and Figure 7 A boss support portion protruding toward the first elastic support section 122 is provided on the first wall 111 of the main body 11; when the male terminal 20 of the connector is inserted into the plug-in channel 110, the first elastic support section 122 abuts against the first area A formed on the top of the boss support portion 1111.

[0063] In another alternative embodiment (not shown), the first elastic support section 122 may be provided with a protruding section facing the first wall 111 of the main body 11; when the male terminal 20 of the connector is inserted into the insertion channel 110, the protruding section of the first elastic support section 122 abuts against the first area A formed on the first wall 111 of the main body 11. Figure 3 and Figure 7 The boss support portion 1111 of the illustrated embodiment is formed as a protruding section on the first elastic support section 122. In this case, the first wall 111 of the main body 11 does not need to be provided with the boss support portion 1111, and the first wall 111 of the main body 11 can be more flat.

[0064] In one embodiment, see Figure 3 and Figure 7 The elastic contact section 121 is provided with a first electrical contact protrusion 1212 protruding toward the second wall 112 of the main body 11, and the second wall 112 of the main body 11 is provided with a second electrical contact protrusion 1121 protruding toward the first electrical contact protrusion 1212; when the male terminal 20 of the connector is inserted into the plug-in channel 110, the first electrical contact protrusion 1212 and the second electrical contact protrusion 1121 clamp the male terminal 20, so that the male terminal 20 is electrically contacted with the connector terminal on both sides, and the electrical connection is more stable.

[0065] In one embodiment, see Figure 3 , in the initial state of the elastic portion 12 (male terminal 20 is not inserted), the second elastic support segment 123 (end portion close to the elastic contact segment 121) is spaced from the elastic contact segment 121 and the support blocking wall 124, the second end of the first elastic support segment 122 abuts against the first wall 111 of the main body 11 in the second region B, and the middle portion of the first elastic support segment 122 is spaced from the first wall 111 of the main body 11. That is, when the male terminal 20 is not inserted, the second elastic support segment 123 does not contact the elastic contact segment 121 and the support blocking wall 124, the second end of the first elastic support segment 122 contacts the first wall 111 of the main body 11, and the middle portion of the first elastic support segment 122 does not contact the first wall 111 (boss support portion 1111) of the main body 11.

[0066] However, in another embodiment (not shown), in the initial state of the elastic portion 12, the second end of the first elastic support segment 122 is spaced from the first wall 111 of the main body 11. That is, when the male terminal 20 is not inserted, the second end of the first elastic support segment 122 does not contact the first wall 111 of the main body 11.

[0067] In one embodiment, see Figure 5, in the initial state of the elastic portion 12, the angle between the second elastic support section 123 and the elastic contact section 121 is a, a≥85°. Preferably, 100°≤a≤130°. More preferably, 120°≤a≤125°. The above value range of the angle a can prevent the second elastic support section 123 from folding inwards when subjected to force, resulting in functional failure.

[0068] In one embodiment, see Figure 5 , in the initial state of the elastic portion 12, the angle b between the elastic contact segment 121 and the support blocking wall 124 is 45°≤b≤135°. Preferably, 70°≤b≤120°. More preferably, 80°≤b≤100°. The above value range of the angle b is conducive to better stopping the second elastic support segment 123.

[0069] In one embodiment, see Figure 6 , the support-blocking wall 124 is at a preset distance from the first wall 111 of the main body 11. The length of the second elastic support portion 123 is c, and the length of the support-blocking wall 124 is d, where c>d. The length c of the second elastic support portion 123 is greater than the length d of the support-blocking wall 124, which can avoid functional failure caused by the support-blocking wall 124 contacting the first wall 111 of the main body 11 after the male terminal 20 is inserted.

[0070] In one embodiment, see Figure 1 , Figure 2 and Figure 4 The main body 11 has a first side wall 113 and a second side wall 114, the first side wall 113 is connected between the first side of the second wall 112 of the main body 11 in the width direction and the first side of the first wall 111 in the width direction, and the second side wall 114 is connected between the second side of the second wall 112 of the main body 11 in the width direction and the second side of the first wall 111 in the width direction; the second wall 112, the first wall 111, the first side wall 113 and the second side wall 114 of the main body 11 enclose the insertion channel 110.

[0071] In one embodiment, see Figure 1 and Figure 2 The second wall 112 includes an inner wall 1122 and an outer wall 1123. The outer wall 1123 is attached to a surface of the inner wall 1122 on a side away from the first wall 111. The inner wall 1122 extends from the top side of the first side wall 113 to the second side wall 114. The outer wall 1123 extends from the top side of the second side wall 114 to the first side wall 113. In this way, the second wall 112 is a double-layer structure, which is beneficial to increase the top strength of the main body 1.

[0072] In one embodiment, see Figure 1 and Figure 2 The side of the outer wall 1123 close to the first side wall 113 is provided with an anti-error plate 1124 extending away from the first wall 111. The anti-error plate 1124 is used for installing and positioning the connector terminal 10 on its housing (usually a plastic housing) to prevent the connector terminal 10 from being inserted into the housing in the wrong direction. The anti-error plate 1124 is substantially perpendicular to the outer second wall 1123.

[0073] In one embodiment, see Figure 1 and Figure 2 The inner wall 1122 is provided with an inner wall support plate 1125 on the side away from the anti-error plate 1124, and the outer wall 1123 is provided with a support hole 1126 on the side close to the inner wall support plate 1125. The inner wall support plate 1125 extends in a direction away from the first wall 111 and passes through the support hole 1126. One or more, for example, two, inner wall support plates 1125 and support holes 1126 are provided in a one-to-one correspondence. The inner wall support plate 1125 and the support hole 1126 form a plug-in fit, and the support hole 1126 is located at the corner where the second side wall 114 and the outer wall 1123 are connected, so as to prevent the outer wall 1123 from being excessively offset when the connector terminal 10 is manufactured.

[0074] In one embodiment, see Figure 1 and Figure 2 , further comprising a crimping portion 2 connected to one end of the plug-in portion 1, the crimping portion 2 comprising a conductor clamp 21 and an insulating clamp 22 connected to the side of the conductor clamp 21 away from the main body 11, the conductor clamp 21 is used to crimp the wire of the cable (the end is stripped of the outer skin), and the insulating clamp 22 is used to clamp the cable (the part without the outer skin); the conductor clamp 21 comprises two conductor clamp wings 211, and a wire crimping space 212 is formed between the two conductor clamp wings 211, and the wire crimping space 212 expands gradually in the direction away from the first wall 111. The insulating clamp 22 comprises two insulating clamp wings 221, and a cable clamping space 222 is formed between the two insulating clamp wings 221, and the cable clamping space 222 expands gradually in the direction away from the first wall 111.

[0075] In one embodiment, see Figure 1 and Figure 2 The inner wall of the conductor clamp 21 is provided with a rib structure 213 extending from one of the conductor clamp wings 211 to the other conductor clamp wing 211. The rib structure 213 is used to increase the holding force of the wire and prevent the wire from escaping from the conductor clamp 21.

[0076] In one embodiment, see Figure 1 and Figure 2 The top outer side of each conductor clamp wing 211 is provided with a first chamfer 2111, and the top outer side of each insulation clamp wing 221 is provided with a second chamfer 2211. The first chamfer 2111 is a rounded corner or a beveled corner, and the second chamfer 2211 is a rounded corner or a beveled corner. The first chamfer 2111 is used to avoid interference between the conductor clamp wing 211 on both sides when the wire is crimped, and the second chamfer 2211 is used to avoid interference between the insulation clamp wing 221 on both sides when the wire is crimped.

[0077] See also Fig. 9 Another embodiment of the present invention provides a connector terminal 10, which is Figure 4 The difference of the illustrated embodiment is that the second end of the second elastic support section 123 is provided with a chamfer 1231, and preferably, the chamfer 1231 is a bevel chamfer. When the plug channel 110 is inserted into the male terminal 20 of the connector, the chamfer 1231 is in surface contact with the elastic contact section 121.
