DETAILED DESCRIPTION
[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.
[0032] Example 1
[0033] like Figure 1 As shown, a double floating structure socket connector includes a floating socket 10 and a cabinet panel 30, wherein the floating socket 10 is mounted on the cabinet panel 30, and further includes a PCB board 40 and a fixed socket 20 mounted on the PCB board 40, wherein the fixed socket 20 and the floating socket 10 are matched with each other. The fixed socket 20 mounted on the PCB board 40 and the floating socket 10 mounted on the cabinet panel 30 are matched with each other to form a complete socket connector.
[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a screw hole 32 is provided on the cabinet panel 30, and the floating socket 10 includes a base 11 and a mounting screw 13. A side panel 12 is provided on the base 11, and a screw mounting hole 121 is provided on the side panel 12. The mounting screw 13 passes through the screw mounting hole 121 and then is threadedly matched with the screw hole 32, and a floating gap A50 is provided between the mounting screw 13 and the screw mounting hole 121;
[0035] A contact mounting hole 111 is defined in the base 11 . A contact 14 is mounted inside the contact mounting hole 111 . A floating gap B is defined between the contact 14 and the contact mounting hole 111 .
[0036] In the technical solution of the double floating structure socket connector, 1. There is a floating gap A50 between the mounting screw 13 and the screw mounting hole 121, that is, the floating socket 10 floats relative to the cabinet panel 30; when the floating socket 10 is assembled on the cabinet panel 30, the mounting screw 13 passes through the screw mounting hole 121 and then engages with the screw hole 32 threadedly. Due to the setting of the floating gap A50, the relative position of the floating socket 10 and the cabinet panel 30 can be changed.
[0037] 2. There is a floating gap B between the contact 14 and the contact mounting hole 111 , that is, the contact 14 floats relative to the base 11 , and when the contact 14 is assembled inside the contact mounting hole 111 , the relative position of the contact 14 and the base 11 may change.
[0038] The technical solution decomposes the floating mechanism into a floating socket 10 floating relative to the cabinet panel 30 and a contact member 14 floating relative to the base 11. The floating of the two parts realizes the overall floating docking function of the connector, thereby solving the problem in the prior art that when the relative installation position accuracy of the cabinet and the PCB board is insufficient, the normal docking of the connectors at both ends cannot be guaranteed.
[0039] At the same time, in the technical solution, the floating mechanism is decomposed into two floating parts, which is more suitable for connectors with smaller volumes.
[0040] like Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, it also includes a cable 15 and a locking screw 16, wherein the cable 15 has a core wire 151; a wire outlet hole 31 is provided on the cabinet panel 30; and a cable mounting hole 113 is provided on the base 11 and is connected to the contact mounting hole 111;
[0041] The contact member 14 includes a main body section 141, and a floating gap B-61 is formed between the main body section 141 and the contact member mounting hole 111. The main body section 141 is provided with a threaded hole 1411 longitudinally and a core wire mounting hole 1412 transversely, and the threaded hole 1411 and the core wire mounting hole 1412 are connected.
[0042] When assembling the contact 14 and the base 11, the contact 14 is placed inside the contact mounting hole 111, and the core wire mounting hole 1412 is opposite to the cable mounting hole 113; when assembling the floating socket 10 and the cabinet panel 30, the core wire 151 is passed through the outlet hole 31 and the cable mounting hole 113 and then inserted into the core wire mounting hole 1412, and then the locking screw 16 is threadedly matched with the threaded hole 1411 until the end of the locking screw 16 is against the core wire 151.
[0043] like Figure 4 , Figure 7 As shown, the inner wall of the contact member mounting hole 111 radially extends to form a limiting protrusion 112, and the upper end of the limiting protrusion 112 contacts the lower end of the main body section 141;
[0044] The contact piece 14 includes a pin section 142 formed by extending downward from the main body section 141. The pin section 142 passes through the middle of the limiting protrusion 112, and a floating gap B262 is provided between the pin section 142 and the limiting protrusion 112. A limiting protrusion 1421 is provided on the pin section 142, and a clamping ring 17 is provided on a section of the pin section 142 located between the limiting protrusion 112 and the limiting protrusion 1421.
[0045] In the present technical solution, when the contact 14 is assembled inside the base 11, the contact 14 is inserted into the contact mounting hole 111 from above until the limiting protrusion 112 contacts the main body section 141, the limiting protrusion 112 supports the main body section 141, and the retaining ring 17 is assembled between the limiting protrusion 112 and the limiting protrusion 2 1421 and sleeved on the pin section 142, so that the contact 14 is limited inside the base 11.
[0046] In the present technical solution, the floating gap B is divided into a floating gap B-61 between the main body section 141 and the contact mounting hole 111, and a floating gap B-62 between the pin section 142 and the limiting protrusion 112. While satisfying the assembly problem between the contact 14 and the base 11, it also satisfies the requirement that there is a gap between the contact 14 and the contact mounting hole 111, and the contact 14 has a floating function relative to the base 11.
[0047] like Figure 8 As shown, the clamp ring 17 has an opening 171, the inner ring of the clamp ring 17 is provided with an inner chamfer 172, and the outer ring of the clamp ring 17 is provided with an outer chamfer 173. The opening 171 and the inner chamfer 172 are provided to facilitate the clamp ring 17 to be pressed into the contact piece 14. After the clamp ring 17 is pressed into the contact piece 14, the clamp ring 17 is shrunken and shaped by a tooling to restore the plastic deformation of the clamp ring 17 pressed into the contact piece 14, so as to ensure that the clamp ring 17 has sufficient supporting strength; the outer chamfer 173 is provided to facilitate the press-fitting of the clamp ring 17 shrinking tooling.
[0048] like Figure 4, Figure 6 As shown, the base 11 is provided with an observation hole 114 which is connected with the contact mounting hole 111; the core wire mounting hole 1412 passes through the contact 14;
[0049] When the cable 15 is assembled to the base 11 , the core wire 151 passes through the core wire installation hole 1412 and is inserted into the interior of the observation hole 114 , thereby lengthening the effective crimping length of the core wire 151 .
[0050] To improve the stability of the assembly between the mounting screws 13 and the side plate 12, as Figure 3 As shown, when the mounting screw 13 is inserted into the screw mounting hole 121 , a sleeve 18 is sleeved thereon.
[0051] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
