[0024] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 Schematic diagrams of the appearance of a multi-purpose socket electrical connector 11, a first plug electrical connector 12 and a second plug electrical connector 13 in different viewing angles according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the first plug electrical connector 12 and / or the second plug electrical connector 13 can form an electrical connector set 1 with the multi-purpose socket electrical connector 11, wherein the first plug electrical connector 12 can be installed on a first wire (not shown in the figure) electrically connected to a first device (not shown in the figure), the second plug electrical connector 13 can be installed on a second wire (not shown in the figure) electrically connected to a second device (not shown in the figure), the multi-purpose socket electrical connector 11 can be installed on a third device (not shown in the figure) and is compatible with the first plug electrical connector 12 and the second plug electrical connector 13, and the multi-purpose socket electrical connector 11 can be used to selectively connect with the first plug electrical connector 12 to establish an electrical connection between the first device and the third device through the first wire, or connect with the second plug electrical connector 13 to establish an electrical connection between the second device and the third device through the second wire.

[0025] Preferably, if Figure 1 and Figure 2 As shown, the first electrical plug connector 12 and the second electrical plug connector 13 may be a push-pull type plug connector having an inner snap-fit ​​structure 122 and a push-pull type plug connector having an outer snap-fit ​​structure 133 , respectively.

[0026] See also Figures 3 to 6, Figure 3 1 is a cross-sectional schematic diagram of a multi-purpose socket electrical connector 11 according to an embodiment of the present invention. Figure 4 This is a partial structural enlarged schematic diagram of a multi-purpose socket electrical connector 11 according to an embodiment of the present invention. Figure 5 Schematic diagram of the multi-purpose socket electrical connector 11 and the first plug electrical connector 12 docking according to an embodiment of the present invention. Figure 6 FIG. 1 is a schematic diagram of the multi-purpose socket electrical connector 11 and the second plug electrical connector 13 docking in accordance with an embodiment of the present invention. Figures 3 to 5 As shown, in order to achieve the connection between the multi-purpose socket electrical connector 11 and the first plug electrical connector 12, the first plug electrical connector 12 includes a first plug-in component 121 and an internal snap-fit ​​structure 122 installed on the first plug-in component 121, and the multi-purpose socket electrical connector 11 includes a receiving component 111 and a first matching structure 112 recessed in the inner wall of the receiving component 111. When the multi-purpose socket electrical connector 11 and the first plug electrical connector 12 are connected to each other, the receiving component 111 is used to at least partially accommodate the first plug-in component 121 and the internal snap-fit ​​structure 122, and the first matching structure 112 is used to snap into the internal snap-fit ​​structure 122, so that the multi-purpose socket electrical connector 11 and the first plug electrical connector 12 can be locked with each other to avoid accidental separation of the multi-purpose socket electrical connector 11 and the first plug electrical connector 12.

[0027] Specifically, the inner snap-in structure 122 may be an inner latch structure having at least one latch hook, and the first matching structure 112 may be an inner groove structure for engaging with the latch hook of the inner latch structure. It is understandable that the inner snap-in structure 122 may be elastically moved outward or deformed to engage with the first matching structure 112, and the first plug electrical connector 12 further includes a first operating member 123. For example, the first operating member 123 may be a sliding sleeve that can slide relative to the first plug-in member 121. The first operating member 123 may be used to slide against the inner snap-in structure 122 to elastically move or deform inward to disengage from the first matching structure 112.

[0028] In this embodiment, the receiving member 111 includes an insertion end 111A and a fixed end 111B, and the insertion end 111A and the fixed end 111B of the receiving member 111 are opposite to each other along a length direction L of the receiving member 111, and the first matching structure 112 is located between the insertion end 111A and the fixed end 111B of the receiving member 111 along the length direction L of the receiving member 111 and is adjacent to the insertion end 111A of the receiving member 111.

[0029] Preferably, if Figure 3 , Figure 4 As shown, a thickness T of the thinnest portion of the receiving member 111 corresponding to a portion where the first matching structure 112 is formed may be 0.1 to 0.2 cm.

[0030] Furthermore, the multi-purpose socket electrical connector 11 further includes a guiding structure 113, whose protrusion is formed on the inner wall of the receiving piece 111 and is located between the insertion end 111A of the receiving piece 111 and the first matching structure 112 along the length direction L of the receiving piece 111. The guiding structure 113 includes a guiding inclined surface 1131, and the guiding inclined surface 1131 is used to abut and match with the inner snap structure 122 of the first plug electrical connector 12. Before the inner snap structure 122 of the first plug electrical connector 12 and the first matching structure 112 are completely engaged with each other, the guiding inclined surface 1131 of the guiding structure 113 can push the inner snap structure 122 to elastically move inward or deform, thereby increasing the engagement feel generated by the inner snap structure 122 of the first plug electrical connector 12 and the first matching structure 112 during the engagement process. The user can thereby determine that the multi-purpose socket electrical connector 11 and the first plug electrical connector 12 are correctly connected to each other by the engagement feel.

[0031] Preferably, the cavity inner diameter defined by a portion of the guide slope 1131 close to the first matching structure 112 is smaller than the cavity inner diameter defined by a portion of the guide slope 1131 close to the insertion end 111A of the receiving member 111, and the cavity inner diameter defined by the guide slope 1131 gradually decreases from the insertion end 111A of the receiving member 111 toward the first matching structure 112.

[0032] Furthermore, if Figure 4 As shown, the first matching structure 112 includes two matching inclined surfaces 1121 and 1122 that are inclined and connected to each other, the guiding inclined surface 1131 of the guiding structure 113 and the matching inclined surface 1121 of the first matching structure 112 are connected to each other by at least one arc surface AS1, the guiding inclined surface 1131 of the guiding structure 113 and the end surface of the insertion end 111A of the receiving piece 111 are connected to each other by at least one arc surface AS2, the two matching inclined surfaces 1121 and 1122 of the first matching structure 112 are connected to each other by at least one arc surface AS3, and the end surface of the insertion end 111A of the receiving piece 111 and the outer wall surface of the insertion end 111A of the receiving piece 111 are connected to each other by at least one arc surface AS4.

[0033] Preferably, if Figure 3 and Figure 4 As shown, in order to enable the inner snap structure 122 of the first plug electrical connector 12 and the first mating structure 112 to engage with each other without hindrance, the radius of the arc surface AS1 can be 0.05 to 0.2 cm, the radius of the arc surface AS2 can be 0.1 to 0.3 cm, the radius of the arc surface AS3 can be 0.15 to 0.25 cm, the radius of the arc surface AS4 can be 0.1 to 0.2 cm, and the inner diameter D1 of a cavity defined by the most protruding part of the arc surface AS1 can be 11.9 to 12.7 cm.

[0034] like Figure 3 , Figure 4 and Figure 6 As shown, in order to achieve the connection between the multi-purpose socket electrical connector 11 and the second plug electrical connector 13, the second plug electrical connector 13 includes a second plug-in component 131, an outer ring structure 132 and an outer snap-fit ​​structure 133 installed on the outer ring structure 132. The multi-purpose socket electrical connector 11 also includes a second matching structure 114 recessed in the outer wall of the receiving component 111. When the multi-purpose socket electrical connector 11 and the second plug electrical connector 13 are connected to each other, the receiving component 111 is used to at least partially accommodate the second plug-in component 131 and is located between the second plug-in component 131 and the outer ring structure 132, and the second matching structure 114 is used to engage with the outer snap-fit ​​structure 133, so that the multi-purpose socket electrical connector 11 and the second plug electrical connector 13 can be locked with each other to avoid accidental separation of the multi-purpose socket electrical connector 11 and the second plug electrical connector 13.

[0035] Specifically, the outer snap-fit ​​structure 133 may be an outer latch structure having at least one latch hook, and the second matching structure 114 may be an outer groove structure for engaging with the latch hook of the outer latch structure. It is understandable that the outer snap-fit ​​structure 133 may be elastically moved inward or deformed to engage with the second matching structure 114, and the second plug electrical connector 13 further includes a second operating member 134. For example, the second operating member 134 may be a sliding sleeve that can slide relative to the second plug-in member 131. The second operating member 134 may be used to slide against the outer snap-fit ​​structure 133 to elastically move or deform the outer snap-fit ​​structure 133 outward to disengage from the second matching structure 114.

[0036] In this embodiment, the second matching structure 114 is located between the first matching structure 112 and the fixed end 111B of the receiving member 111 along the length direction L of the receiving member 111 .

[0037] Furthermore, if Figure 3 , Figure 4 and Figure 6As shown, the multi-purpose socket electrical connector 11 further includes a push structure 115, whose protrusion is formed on the outer wall of the receiving piece 111 and is located between the insertion end 111A of the receiving piece 111 and the second matching structure 114 along the length direction L of the receiving piece 111. The push structure 115 is used to abut and match with the outer snap structure 133 of the second plug electrical connector 13. Before the outer snap structure 133 of the second plug electrical connector 13 and the second matching structure 114 are completely engaged with each other, the push structure 115 can push the outer snap structure 133 to elastically move outward or deform, thereby increasing the engagement feel generated by the outer snap structure 133 of the second plug electrical connector 13 and the second matching structure 114 during the engagement process. The user can thereby determine that the multi-purpose socket electrical connector 11 and the second plug electrical connector 13 are correctly connected to each other by the engagement feel.

[0038] Furthermore, if Figure 4 As shown, the second matching structure 114 includes an inclined surface 1141, a first plane 1142 and a second plane 1143 connected to the inclined surface 1141 and the first plane 1142, the first plane 1142 is perpendicular to the length direction L, the second plane 1143 is parallel to the length direction L, that is, the second plane 1143 is perpendicular to the first plane 1142, the first plane 1142 of the second matching structure 114 and the outer wall surface of a middle portion 111C of the receiving member 111 are connected to each other through at least an arc surface AS5, wherein the middle portion 111C of the receiving member 111 is located between the insertion end 111A and the fixed end 111B of the receiving member 111 along the length direction L of the receiving member 111.

[0039] Preferably, if Figure 3 and Figure 4 As shown, in order to enable the outer snap structure 133 of the second plug electrical connector 13 and the second mating structure 114 to engage with each other without hindrance, the radius of the arc surface AS5 can be 0.05 to 0.15 cm, and the distance H1 between the connection between the two mating inclined surfaces 1121 and 1122 of the first mating structure 112 and the first plane 1142 of the second mating structure 114 can be 3.63 to 3.73 cm.

[0040] like Figures 3 to 6As shown, the multi-purpose socket electrical connector 11 further includes an abutting boss 116 and a transition platform 117. The abutting boss 116 is protruded from the inner wall of the receiving piece 111 and is located between the first matching structure 112 and the fixed end 111B of the receiving piece 111 along the length direction L of the receiving piece 111. The transition platform 117 is formed on the inner wall of the receiving piece 111 and is located between the first matching structure 112 and the abutting boss 116 along the length direction L of the receiving piece 111. When the multi-purpose socket electrical connector 11 and the first plug electrical connector 12 are connected to each other, the abutment boss 116 and the transition platform 117 can be used to abut and cooperate with the end of the first plug-in component 121 of the first plug electrical connector 12. The abutment and cooperation between the transition platform 117 and the end of the first plug-in component 121 of the first plug electrical connector 12 can provide a certain degree of sealing effect to prevent external dust and moisture from contacting the terminals of the multi-purpose socket electrical connector 11 and the first plug electrical connector 12, thereby protecting the terminals of the multi-purpose socket electrical connector 11 and the first plug electrical connector 12; the abutment and cooperation between the abutment boss 116 and the end of the first plug-in component 121 of the first plug electrical connector 12 can prevent the first plug electrical connector 12 from shaking relative to the multi-purpose socket electrical connector 11, thereby ensuring the connection between the multi-purpose socket electrical connector 11 and the first plug electrical connector 12.

[0041] When the multi-purpose socket electrical connector 11 and the second plug electrical connector 13 are connected to each other, the abutment boss 116 and the transition platform 117 can be used to abut and cooperate with the end of the second plug-in component 131 of the second plug electrical connector 13. The abutment and cooperation between the transition platform 117 and the end of the second plug-in component 131 of the second plug electrical connector 13 can provide a certain degree of sealing effect to prevent external dust and moisture from contacting the terminals of the multi-purpose socket electrical connector 11 and the second plug electrical connector 13, thereby protecting the terminals of the multi-purpose socket electrical connector 11 and the second plug electrical connector 13; the abutment and cooperation between the abutment boss 116 and the end of the second plug-in component 131 of the second plug electrical connector 13 can prevent the second plug electrical connector 13 from shaking relative to the multi-purpose socket electrical connector 11, thereby ensuring the connection between the multi-purpose socket electrical connector 11 and the second plug electrical connector 13.

[0042] Preferably, if Figure 3 and Figure 4 As shown, in order to ensure that the abutment boss 116 and the transition platform 117 can correctly and unhinderedly abut against the end of the first plug-in component 121 and the end of the second plug-in component 131 to achieve the above-mentioned sealing and anti-shaking effects, the inner diameter D2 of a chamber defined by the transition platform 117 can be 12.1 to 12.5 cm, and a distance H2 between the junction of the transition platform 117 and the abutment boss 116 and the end face of the insertion end 111A can be 4.2 to 4.3 cm.

[0043] It is worth noting that the multi-purpose socket electrical connector 11 can be made of a cut-pin stainless steel material so that the multi-purpose socket electrical connector 11 can not only meet the above-mentioned size requirements, but also have a better structural strength.

[0044] See also Figure 7 , Figure 7 FIG. 1 is a schematic diagram of a multi-purpose socket electrical connector 11' and a third plug electrical connector 14' docking with each other according to another embodiment of the present invention. Figure 7 As shown, the multi-purpose socket electrical connector 11' of this embodiment is similar to the multi-purpose socket electrical connector 11 of the first embodiment. Unlike the first embodiment, the multi-purpose socket electrical connector 11' of this embodiment is compatible with the first plug electrical connector, the second plug electrical connector and the third plug electrical connector 14' which is different from the first plug electrical connector and the second plug electrical connector. At least one of the first plug electrical connector, the second plug electrical connector and the third plug electrical connector 14' can form an electrical connector set 1' with the multi-purpose socket electrical connector 11'. Specifically, the multi-purpose socket electrical connector 11' of this embodiment further includes a third matching structure 118' formed on an abutting boss 116'. The third matching structure 118' is used to lock with a locking structure 142' of the third plug electrical connector 14' when a receiving member 111' partially receives a third plug-in member 141' of the third plug electrical connector 14'. For example, the locking structure 142' can be an external thread structure different from the internal and external latch structures with hooks, and the third matching structure 118' can be an internal thread structure that matches the locking structure 142'. The other structures of this embodiment are the same as those of the first embodiment and also have similar variations, so they are not repeated here for the sake of brevity.

[0045] Compared to the prior art, the multi-purpose socket electrical connector of the present invention can selectively utilize the first mating structure to engage with the inner snap structure of the first plug electrical connector, or utilize the second mating structure to engage with the outer snap structure of the second plug electrical connector. Therefore, the multi-purpose socket electrical connector of the present invention can effectively avoid the replacement or switching operations derived from the incompatibility between electrical connectors during on-site construction, thereby improving the convenience of use.
