[0039] Please refer to Figures 1 to 18 As shown, this utility model discloses an electrical connector, including an insulating body 1, a first terminal module 2 and a second terminal module 3. The insulating body 1 has a storage space 10 and a mating interface 10a. The first terminal module 2 and the second terminal module 3 are at least partially disposed in the storage space 10. The mating interface 10a is used for mating connector insertion.

[0040] See Figures 2-4The insulating body 1 includes a top wall portion 11, a bottom wall portion 12 opposite to the top wall portion 11, and two side wall portions 13. The two side wall portions 13 are respectively connected to the two sides of the top wall portion 11 and the bottom wall portion 12. The top wall portion 11, the bottom wall portion 12, and the two side wall portions 13 together form the storage space 10.

[0041] See Figures 6-8 The top wall portion 11 of the insulating body 1 is provided with a first engaging portion 14 located in the storage space 10. The first terminal module 2 is provided with a second engaging portion 215. The second engaging portion 215 is located between the two first side portions 211 of the first terminal module 2 along a first direction A1-A1. The second engaging portion 215 engages with the first engaging portion 14 and supports each other along a second direction A2-A2. The second direction A2-A2 is perpendicular to the first direction A1-A1. See also Figure 10 and Figure 11 The bottom wall portion 12 of the insulating body 1 is provided with a fifth engaging portion 15 located in the storage space 10, and the second terminal module 3 is provided with a sixth engaging portion 315. The sixth engaging portion 315 is located between the two second side portions 311 of the second terminal module 3 along the first direction A1-A1. The sixth engaging portion 315 engages with the fifth engaging portion 15 and supports each other along the second direction A2-A2, wherein the first direction A1-A1 refers to the left-right direction of the electrical connector, and the second direction A2-A2 refers to the up-down direction of the electrical connector. The first terminal module 2 and the second terminal module 3 are arranged along the up-down direction of the electrical connector. The second engaging portion 215 supports the first engaging portion 14, and the sixth engaging portion 315 supports the fifth engaging portion 15. This solves the deformation problem of the first terminal module 2 and the second terminal module 3 in the second direction A2-A2, which is beneficial to maintaining the consistency of the terminal bullet height.

[0042] See Figures 6-8 The first engaging portion 14 includes a first slot 141, and the second engaging portion 215 is a protruding structure extending from the first terminal module 2 along a third direction A3-A3, extending into the first slot 141. The third direction A3-A3 refers to the front-rear direction of the electrical connector. Of course, in some other embodiments, the positions of the first engaging portion 14 and the second engaging portion 215 can be interchanged. For example, a structure similar to the first engaging portion 14 can be provided on the first terminal module 2, and a structure similar to the second engaging portion 215 can be provided on the insulating body 1, as long as the first terminal module 2 and the insulating body 1 can be mutually engaged. This application is not limited to the illustrated embodiments.

[0043] See Figure 10 and Figure 11 The fifth engaging portion 15 includes a second engaging slot 151, and the sixth engaging portion 315 is a protruding structure extending from the second terminal module 3 along the third direction A3-A3, extending into the second engaging slot 151. Of course, in some other embodiments, the fifth engaging portion 15 and the sixth engaging portion 315 can be interchanged. For example, a structure similar to the fifth engaging portion 15 can be provided on the second terminal module 3, and a structure similar to the sixth engaging portion 315 can be provided on the insulating body 1, as long as the second terminal module 3 and the insulating body 1 can be mutually engaged. This application is not limited to the illustrated embodiments.

[0044] See Figure 7 The first slot 141 includes two first groove surfaces 1411 disposed opposite each other along the second direction A2-A2. The two first groove surfaces 1411 are used to support the second engaging portion 215. (See also...) Figure 11 The second slot 151 includes two second groove surfaces 1511 arranged opposite each other along the second direction A2-A2, which are used to support the sixth engaging portion 315. The first groove surface 1411 supports the second engaging portion 215, and the second groove surface 1511 supports the sixth engaging portion 315, making it less prone to deformation of the first terminal module 2 and the second terminal module 3 in the second direction A2-A2, which helps maintain the consistency of the terminal bullet height.

[0045] In some implementations, see Figure 12 The second engaging portion 215 includes two spaced-apart first protrusions 2151, and correspondingly, the first engaging portion 14 includes two first slots 141. Of course, in other possible embodiments, the second engaging portion 215 may include one first protrusion 2151, or the second engaging portion 215 may include three spaced-apart first protrusions 2151. In this utility model, the specific number of first protrusions 2151 is not limited.

[0046] In some implementations, see Figure 12 The sixth engaging portion 315 includes two spaced-apart second protrusions 3151, and correspondingly, the fifth engaging portion 15 includes two second slots 151. Of course, in other possible embodiments, the sixth engaging portion 315 may include one second protrusion 3151, or it may include three spaced-apart second protrusions 3151. In this invention, the specific number of second protrusions 3151 is not limited.

[0047] The lengths of the first protrusion 2151 and the second protrusion 3151 along the first direction A1-A1 can be adjusted as needed. For example, when the dimensions of the first terminal module 2 and the second terminal module 3 along the first direction A1-A1 are large, the lengths of the first protrusion 2151 and the second protrusion 3151 can be appropriately increased while keeping the number unchanged, thereby increasing the support effect. Of course, the number of the first protrusion 2151 and the second protrusion 3151 can also be increased to increase the support effect.

[0048] See Figure 7 The second engaging portion 215 is provided with a first guide surface 2150 inclined relative to the third party towards A3-A3, see [link / reference]. Figure 14 The opening of the first slot 141 is provided with a second guide surface 1412 inclined relative to the third direction A3-A3. By providing the first guide surface 2150 and the second guide surface 1412, a guiding function is provided during the mutual insertion of the second engaging portion 215 and the first slot 141. (See also...) Figure 11 The sixth engaging portion 315 is provided with a third guide surface 3150 that is inclined relative to the third party towards A3-A3, and the opening of the second slot 151 is provided with a fourth guide surface 1512 that is inclined relative to the third party towards A3-A3. By providing the third guide surface 3150 and the fourth guide surface 1512, they play a guiding role during the mutual insertion of the sixth engaging portion 315 and the second slot 151.

[0049] At least one of the two surfaces of the first protrusion 2151 that mates with the two first groove surfaces 1411 is an inclined first guide surface 2150. In this embodiment, see [reference needed]. Figure 7 The surface of the first protrusion 2151 facing the second terminal module 3 is an inclined first guide surface 2150. Correspondingly, the first groove surface 1411 that mates with the first guide surface 2150 is also an inclined surface. See also Figure 11 The third guide surface 3150 is formed by setting a chamfer at the free end of the second protrusion 3151.

[0050] The first protrusion 2151 and the second protrusion 3151 can also have the same structure. For example, the second protrusion 3151 can be configured in a shape similar to the first protrusion 2151, or the first protrusion 2151 can be configured in a shape similar to the second protrusion 3151.
