DETAILED DESCRIPTION

[0049] The utility model is further described in detail below in conjunction with the accompanying drawings. Example 1

[0050] See also Figure 3 , Figure 4 and Figure 6 An electrical connector unit includes a housing 1, a conductive core 2 detachably installed in the housing 1, and a positioning member 5 for fixing the conductive core 2.

[0051] The housing 1 is penetrated by a through hole 3 , and two ends of the through hole 3 are respectively a first port 31 and a second port 32 .

[0052] The conductive core 2 needs to be inserted into the through hole 3 from the second port 32 and extended from the first port 31 to achieve installation.

[0053] The housing 1 is provided with a positioning hole 6 connected to the through hole 3, and the penetration direction of the positioning hole 6 is perpendicular to the penetration direction of the through hole 3. The positioning member 5 penetrates the positioning hole 6 and contacts the conductive core 2 in the through hole 3 to limit the conductive core 2 from moving along the through hole 3.

[0054] A protective wall 4 is fixed to the first port 31 of the housing 1, and the protective wall 4 is integrally formed with the housing 1. The protective wall 4 surrounds the outer edge of the first port 31 to accommodate the first port 31 therein.

[0055] When the conductive core 2 needs to be installed, first insert the conductive core 2 from the second port 32; push the conductive core 2 to move along the through hole 3 until one end of the conductive core 2 enters the first port 31; then insert the positioning member 5 into the positioning hole 6. Since the positioning hole 6 is connected to the through hole 3, the positioning member 5 contacts the conductive core 2 in the through hole 3 to limit the conductive core 2 from sliding in the length direction of the through hole 3.

[0056] Electrical connector units are usually used in pairs. When two electrical connection units are plugged in for electrical connection, the two protective walls 4 first contact each other to form a protective cavity 13. The two conductive cores 2 are electrically connected in the protective cavity 13 to prevent users from accidentally touching the conductive cores 2, which is beneficial to ensure the safety of the electrical connection operation.

[0057] Specifically, the positioning member 5 is a buckle 51. After the buckle 51 is inserted into the positioning hole 6, the buckle 51 is fixedly engaged with the positioning hole 6. The positioning hole 6 is a through hole, and the user can easily push out the buckle 51 from the reverse side.

[0058] Specifically, the conductive core 2 is penetrated by two waist holes 23. When the buckle 51 is fixed in the positioning hole 6, the buckle 51 passes through the two waist holes 23 and contacts the hole wall of the waist hole 23 to limit the movement of the conductive core 2 along the length direction of the through hole 3. In addition, the buckle 51 cooperates with the two waist holes 23 to limit the rotation of the conductive core 2 in the horizontal plane relative to the buckle 51, that is, to prevent the conductive core 2 from rotating relative to the housing 1, so as to ensure that the conductive core 2 is maintained at the specified position of the housing 1, which is conducive to ensuring the reliability of the electrical connection.

[0059] The buckle 51 is n-shaped and integrally formed with a positioning protrusion 511. After the buckle 51 is inserted into the designated position of the positioning hole 6, the positioning protrusion 511 is engaged with the inner hole wall of the positioning hole 6 to achieve the buckle being fixed in the positioning hole 6.

[0060] A mounting hole 10 is provided on the side of the conductive core 2 facing away from the housing 1 , and the mounting hole 10 is used for fixed connection with a cable to enable the conductive core 2 to be energized.

[0061] A plurality of process holes 7 are provided on the outer wall of the shell 1 . The process holes 7 are located on the outer surfaces of both sides of the shell 1 , which is beneficial to reducing the material consumption of the shell 1 and reducing the cost.

[0062] The electrical connector unit may be a plug or a socket. In the present embodiment, the electrical connector unit is a socket.

[0063] The housing 1 on the socket is a first housing 11, and the conductive core 2 is a first electric core 21. A slot 41 is provided on the protective wall 4 for mating with a plug.

[0064] The protective wall 4 completely surrounds the end of the first core, so that the first core is maintained in the through hole 3. The protective wall 4 is integrally formed with the first shell 11, and the first port 31 is formed by the protective wall 4. The plug can only be extended into the protective wall 4 and pass through the first port 31 to make electrical contact with the first core, which is conducive to ensuring the safety of the electrical connection and reducing the possibility of the user accidentally touching the first core.

[0065] One end of the first core is provided with a plug slot 14 for electrically connecting with a plug.

[0066] The inner wall of the slot 41 is provided with a foolproof rib 411 for mating with the plug. There are two foolproof ribs 411, which are distributed on both sides of the conductive core 2. The ribs are fixed on the inner wall of the slot 41 away from the conductive core 2 and are integrally formed with the housing 1 to prevent the foolproof structure from interfering with the electrical connection of the conductive core 2. Example 2

[0067] The difference between this embodiment and the first embodiment is that:

[0068] See also Figure 1 , Figure 2 ,as well as Figures 8 to 11 The electrical connection unit in this embodiment is a plug, the housing 1 on the plug is the second housing 12, and the conductive core 2 is the second core. The protective wall 4 is integrally formed with the second housing 12 and surrounds the conductive core 2 extending out of the first port 31.

[0069] The outer side wall of the protection wall 4 is provided with an anti-mistake groove 42 for cooperating with the socket. The anti-mistake groove 42 extends along the length direction of the socket and penetrates the protection wall 4 to form an opening 421.

[0070] When the plug and the socket are mated, the protective wall 4 of the plug contacts the protective wall 4 of the socket, and the foolproof rib 411 faces the opening 421 of the foolproof groove 42; if the specifications of the socket and the plug match each other, the foolproof rib 411 of the socket can enter the foolproof groove 42 through the opening 421 and slide along the foolproof groove 42. The cooperation of the two foolproof ribs 411 and the two foolproof grooves 42 can make the first shell 11 and the second shell 12 slide smoothly when plugged in, so as to reduce the possibility of the first shell 11 deflecting or moving relative to the second shell 12, which is conducive to ensuring the reliability of plugging.

[0071] The plug and socket connection process is as follows:

[0072] 1. The first core contacts the protective wall 4 of the socket and is inserted into the second shell 12;

[0073] 2. The protective wall 4 of the plug contacts the protective wall 4 of the socket, and the protective wall 4 of the plug is inserted into the slot 41 of the socket. The foolproof groove 42 cooperates with the foolproof rib 411 to prevent misconnection of plugs and sockets of different specifications;

[0074] 3. The protective wall 4 of the plug and the protective wall 4 of the socket are combined to form a closed protective cavity 13, and the second core and the first core are both located in the protective cavity 13;

[0075] 4. Continue to push the plug and the socket closer together, and the space of the protective cavity 13 gradually shrinks;

[0076] 5. The second core is completely inserted into the insertion slot 14 of the first core, the protective wall 4 of the plug is completely inserted into the slot 41, the first core is in full electrical contact with the second core, and the plug and socket are plugged in. Example 3

[0077] The difference between this embodiment and the first embodiment is that:

[0078] See also Figure 5 and Figure 6 , a socket assembly, a mounting bracket 8, and a plurality of sockets fixed on the mounting bracket 8.

[0079] By docking the socket assembly with the plug assembly, the electrical connection of multiple pairs of plugs and sockets can be completed at one time, reducing the electrical connection process to improve production efficiency.

[0080] The mounting bracket 8 is provided with a partition plate 9 for separating adjacent sockets, and the number of the partition plates 9 is one less than the number of the sockets. The partition plate 9 can increase the spacing and creepage distance between adjacent sockets, and increase the reliability of the socket assembly when combined and connected. Example 4

[0081] The difference between this embodiment and the second embodiment is that:

[0082] See also Figure 7 , a plug assembly, a mounting bracket 8, and a plurality of plugs fixed on the mounting bracket 8.

[0083] By docking the socket assembly with the plug assembly, the electrical connection of multiple pairs of plugs and sockets can be completed at one time, reducing the electrical connection process to improve production efficiency.
