Description

Technical Field

[0001] This invention relates to the field of connectors, and in particular to an electrical connector. Background Technology

[0002] In existing servers, electrical connectors are indispensable components, used for connection with external connectors. Commonly used electrical connectors in existing servers typically include a base and multiple terminal modules. One side of the base forms multiple raised, hollow main terminal blocks, with each terminal module fixed to the base and inserted into its respective main terminal block. External connectors commonly used in servers typically include a base and multiple main external connection terminals. One side of the base forms a ring of raised flanges, with each main external connection terminal fixed to the base and located inside the flanges. When the electrical connector connects to the external connector, the main terminal blocks and terminal modules of the base are inserted into the flanges of the external connector, and the terminal modules and main external connection terminals interlock.

[0003] However, when existing electrical connectors are connected to high-current cables, the large diameter and heavy weight of these cables cause them to bend due to the connection direction and installation space constraints. This results in significant tensile force on the electrical connector, which can easily cause it to detach from the external connector. Even with screws to secure the connector, the main terminal block can deform and be damaged due to excessive force.

[0004] In view of the above problems, it is necessary to study an electrical connector to overcome the shortcomings of the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide an electrical connector that overcomes the shortcomings of the prior art.

[0006] To achieve the above objectives, the solution of the present invention is: An electrical connector includes a base and a plurality of terminal modules; the base has an integrally formed support wall and a plurality of main terminal blocks protruding from its insertion side, with a space between the support wall and each main terminal block; the support wall has at least two opposing support end faces; each main terminal block is located between the two opposing support end faces of the support wall; each main terminal block has a through hole penetrating the base; and each terminal module is respectively installed in the through hole of each main terminal block.

[0007] Furthermore, the terminal module has a receiving cavity at one end near the base on the plug-in side, and the receiving cavity has an annular terminal.

[0008] Furthermore, a resilient anti-reverse element is provided between the terminal module and the base.

[0009] Furthermore, the support wall has a ring structure and surrounds each main terminal block.

[0010] Furthermore, at least one observation hole is provided on the support wall near the base insertion side.

[0011] Furthermore, the support wall has multiple observation holes, with each observation hole positioned in the gap between two main terminal blocks.

[0012] Furthermore, at least one main terminal block has reinforcing ribs on its outer wall.

[0013] Furthermore, the height of the main terminal block is greater than the height of the support wall.

[0014] Furthermore, the base also has multiple integrally formed secondary terminal blocks protruding from the plug-in side. Each secondary terminal block is located between two main terminal blocks. The height of the secondary terminal block is lower than the height of the main terminal blocks. The height of the secondary terminal block is equal to or lower than the height of the support wall. Each secondary terminal block is provided with a secondary terminal.

[0015] Furthermore, the outer walls of the main terminal blocks located on both sides of the secondary terminal block are provided with reinforcing ribs, and these reinforcing ribs do not face the secondary terminal blocks.

[0016] With the above solution, when the electrical connector of the present invention is connected to an external connector, each main terminal block and terminal module of the base of the present invention is inserted into the inner side of the retaining edge of the base of the external connector, and each terminal module of the electrical connector of the present invention is plugged into each main external connection terminal of the external connector. Meanwhile, each support end face of the support wall of the base is abutted against the outer side of the retaining edge of the base, thereby enabling the retaining edge of the base to support the electrical connector and strengthen the support of the external connector on the electrical connector. This prevents the electrical connector from coming out due to the pulling effect of the cable connected to the electrical connector and / or the main terminal block of the electrical connector from deforming and being damaged.

[0026] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0027] like Figure 1 and Figure 2 As shown, the present invention discloses an electrical connector 1, which includes a base 11 and a plurality of terminal modules 12; the insertion side 110 of the base 11 is provided with an integrally formed support wall 111 and a plurality of main terminal blocks 112, and a space is left between the support wall 111 and each main terminal block 112 to accommodate the retaining edge 211 of the base 21 of the external connector 2. The support wall 111 has at least two opposing support end faces 1111, and each main terminal block 112 is located between the two opposing support end faces 1111 of the support wall 111. The main terminal block 112 has a through hole 1121 penetrating the base 11, and each terminal module 12 is respectively installed in the through hole 1121 of each main terminal block 112.

[0028] Cooperate Figures 3 to 8As shown, when the electrical connector 1 of the present invention is connected to the external connector 2, each main terminal block 112 and terminal module 12 of the base 11 of the present invention is inserted into the inner side of the retaining edge 211 of the base 21 of the external connector 2, and each terminal module 12 of the electrical connector 1 of the present invention is plugged into each main external connection terminal 22 of the base 21. The supporting end face 1111 of the supporting wall 111 of the base 11 is abutted against the outer side of the retaining edge 211 of the base 21, thereby enabling the retaining edge 211 of the base 21 to support the electrical connector 1 and strengthen the supporting effect of the base 21 on the electrical connector 1, thereby preventing the electrical connector 1 from coming out due to the pulling effect of the cable connected to the electrical connector 1 and / or causing deformation and damage to the main terminal block 112 of the electrical connector 1.

[0029] In an embodiment of the present invention, a receiving cavity 121 is provided at one end of the terminal module 12 near the insertion side 110 of the base 11. The receiving cavity 121 is provided with an annular terminal 122, which is used to be inserted into the main external connection terminal 22 to achieve electrical conduction. In addition, an elastic anti-retraction element 13 is provided between the terminal module 12 and the base 11. The elastic anti-retraction element 13 can effectively prevent the terminal module 12 from coming out of the through hole 1121.

[0030] In embodiments of the present invention, in conjunction with Figure 1 , Figure 2 and Figure 7 As shown, the support wall 111 has a ring structure and surrounds each main terminal block 112. In this way, when the electrical connector 1 of the present invention is connected to the external connector 2, the support wall 111 can completely hold the retaining edge 211 of the base 21, so that the retaining edge 211 of the base 21 can better support the electrical connector 1. It should be noted that the support wall 111 is not limited to a ring structure. The support wall 111 may also include multiple separated support blocks, as long as the support wall 111 has at least two opposing support end faces 1111 to cooperate with the retaining edge 211 of the base 21 so that the retaining edge 211 of the base 21 can support the electrical connector 1.

[0031] In embodiments of the present invention, in conjunction with Figure 1 , Figure 2 and Figure 7 As shown, the support wall 111 is provided with at least one observation hole 1112 near the insertion side 110 of the base 11. When the electrical connector 1 of the present invention is connected to the external connector 2, the user can observe whether the external connector 2 is inserted in place through the observation hole 1112. Specifically, the support wall 111 has multiple observation holes 1112, and the position of each observation hole 1112 corresponds to the gap between the two main terminal blocks 112.

[0032] In embodiments of the present invention, in conjunction with Figure 1 and Figure 2 As shown, the height of the main terminal block 112 can be greater than the height of the support wall 111, so that the main terminal block 112 is exposed outside the support wall 111. This makes it easier for the user to accurately insert each main terminal block 112 and terminal module 12 of the base 11 into the inside of the retaining edge 211 of the base 21 when the electrical connector 1 is connected to the external connector 2.

[0033] In embodiments of the present invention, at least one of the main terminal blocks 112 has a reinforcing rib 1122 on its outer wall, which can effectively improve the strength of the main terminal block 112. Specifically, the outer wall of each main terminal block 112 may be provided with a reinforcing rib 1122.

[0034] In an embodiment of the present invention, the insertion side 110 of the base 11 may also be provided with a plurality of integrally formed secondary terminal blocks 113. Each secondary terminal block 113 is located between two main terminal blocks 112. The height of the secondary terminal block 113 is lower than the height of the main terminal blocks 112. The height of the secondary terminal block 113 is equal to or lower than the height of the support wall 111. Each secondary terminal block 113 is provided with a secondary terminal 14. The diameter of the secondary terminal 14 is smaller than the diameter of the terminal module 12. The secondary terminal 14 can be used to connect with the secondary external connection terminal 23 of the external connector 2. The reinforcing ribs 1122 on the outer walls of the main terminal blocks 112 located on both sides of the secondary terminal blocks 113 do not face the secondary terminal blocks 113.

[0035] In an embodiment of the present invention, the base 11 may be provided with two mating holes 114 for mating with the fixing element 15. The fixing element 15 passes through the mating holes 114 and is rotatably mated with the base 11. The fixing element 15 is used to lock the base 11 and the base 21 of the base body 21, effectively improving the connection stability between the electrical connector 1 and the external connector 2.

[0036] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
