Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a floating connector male end structure and a connector. Background Art

[0002] An electrical connector generally consists of two pluggable electrical connector plugs and sockets; with the continuous development and progress of electric vehicles, electrical connectors are increasingly used in electric vehicles. Since the main energy source of electric vehicles is electricity, and charging the battery is a relatively slow process, the energy replenishment of electric vehicles is generally achieved by replacing the battery.

[0003] When the electrical connector socket on the battery box is plugged into the corresponding electrical connector plug at a charging station or electric vehicle, the positioning accuracy between the two is difficult to ensure and there is often a deviation. Therefore, the corresponding plug and socket are often not properly plugged in. If the plug is forced, the plugging parts of the connector are likely to be damaged, causing irreparable damage.

[0004] In addition, at a charging station or an electric vehicle, the connection between the electrical connector socket on the battery box and the corresponding electrical connector plug may produce relative displacement due to vibration or other uncertain factors. Since the electrical connector plug and socket are fixed on different objects, the relative displacement or relative displacement trend between the two is very likely to cause the connection between the electrical connector plug and the socket to loosen, and even cause destructive damage to the electrical connector plug and socket.

[0005] The utility model with announcement number: CN213989287U discloses a floating connector female seat and a floating connector, wherein the female seat includes an insulating upper seat and a lower seat and a plurality of connecting terminals for signal transmission; the connecting terminal is an elastic metal sheet, including a connecting end, a pin end and a supply-lifting portion located between the connecting end and the pin end, and the supply-lifting portion and the connecting end can be elastically offset along the X-axis and the Y-axis relative to the pin end; the pin end of the connecting terminal is fixed on the lower seat, and a plug-in portion and a receiving groove are provided on the upper seat, the connecting end of the connecting terminal is fixed on the plug-in portion, and the opening of the receiving groove faces downward to accommodate the supply-lifting portion of the connecting terminal, and through the cooperation of the supply-lifting portion and the receiving groove, the upper seat can float slightly relative to the lower seat; in the floating connector with the above structure, the upper seat can drive the supply-lifting portion and the connecting end to send a slight offset relative to the lower seat, thereby reducing the design requirements for the installation tolerance of the connector on the circuit board, effectively reducing the scrap rate of the circuit board, and improving the assembly efficiency of functional devices on the integrated circuit board.

[0006] However, the floating connector in the prior art still has the technical problem of poor floating effect in actual use. Summary of the invention

[0007] The object of the present invention is to provide a floating connector male end structure and a connector, which can effectively solve the technical problem of poor floating effect of the connector in the prior art.

[0009] A floating connector male end structure, comprising a male end body, and further comprising:

[0010] A support plate, wherein the support plate is fixedly arranged at the upper end of the male end body and forms a clearance area between the support plate and the male end body;

[0011] An installation shell, wherein the installation shell is movably installed on the male end body through a floating assembly;

[0012] The floating assembly includes a bolt, a guide head, a nut and a spring. A first clearance hole is provided on the support plate. The upper end of the guide head has a truncated cone structure. A second clearance hole is provided on the mounting housing. The bolt passes through the first clearance hole, the guide head and the second clearance hole in sequence and is connected with the nut. The spring is sleeved on the bolt. Under the action of the spring, the truncated cone structure of the guide head contacts the second clearance hole.

[0013] The signal pin in the male end body is connected with an elastic metal contact after passing through the support plate. A metal cylinder is arranged on the mounting shell. The elastic metal contact is located in the metal cylinder and realizes signal transmission after contact.

[0014] Among them, the metal cylinder includes a cylinder body and a guide pin integrated with the cylinder body, and an installation groove is provided on the installation shell. The installation groove is a stepped groove, and the guide pin passes through the stepped groove. The cylinder body is fixedly arranged in the installation groove, and the elastic metal contact contacts the inner wall of the cylinder.

[0015] Furthermore, the elastic metal contact and the signal pin are connected together by welding.

[0016] Preferably, the elastic metal contact comprises a connecting sleeve and a plurality of metal springs arranged on the connecting sleeve, and the metal springs are arranged obliquely and in close contact with the inner wall of the metal cylinder.

[0017] The end of the metal spring sheet has a contact portion, and the contact portion is in close contact with the inner wall of the metal cylinder.

[0018] Furthermore, a limit platform is arranged inside the mounting shell.

[0019] Preferably, an elastic pad is provided on the limiting platform, and the elastic pad is in contact with the supporting plate.

[0041] See also Figure 1-Figure 5 This embodiment discloses a floating connector male end structure, including a male end body 101, and this embodiment also includes:

[0042] A support plate 102, wherein the support plate 102 is fixedly disposed at the upper end of the male end body 101 and forms a clearance area 103 between the support plate 102 and the male end body 101;

[0043] An installation housing 104, wherein the installation housing 104 is movably installed on the male end body 101 through a floating assembly 105;

[0044] The floating assembly 105 includes a bolt 106, a guide head 107, a nut 108 and a spring 109. The support plate 102 is provided with a first clearance hole 110. The upper end of the guide head 107 has a truncated cone structure 111. The mounting housing 104 is provided with a second clearance hole 112. The bolt 106 passes through the first clearance hole 110, the guide head 107 and the second clearance hole 112 in sequence and is connected with the nut 108. The spring 109 is sleeved on the bolt 106. Under the action of the spring 109, the truncated cone structure 111 of the guide head 107 contacts the second clearance hole 112.

[0045] The signal pin in the male end body 101 passes through the support plate 102 and is connected to the elastic metal contact 113. A metal cylinder 114 is provided on the mounting shell 104. The elastic metal contact 113 is located in the metal cylinder 114 and realizes signal transmission after contact.

[0046] The present invention realizes the connection between the mounting shell 104 and the support plate 102 by setting up a floating component 105, so that the male end of the connector and the female end of the connector 131 can float freely without affecting the signal transmission after the connection, thereby avoiding irreversible damage to the connector; in the present invention, the first clearance hole 110 and the second clearance hole 112 are set to achieve the purpose of giving way during floating, and under the action of the bolt 106, the spring 109 and the guide head 107, the mounting shell 104 and the support plate 102 can achieve relative sliding. Since the guide head 107 is provided with a truncated cone structure 111, and the position can be adjusted after contacting with the second clearance hole 112, in this application, the elastic metal contact 113 and the metal cylinder 114 are set to ensure close contact while achieving signal transmission.

[0047] The metal cylinder 114 includes a cylinder 115 and a guide pin 116 integrated with the cylinder 115. The mounting housing 104 is provided with a mounting groove 117, which is a stepped groove. The guide pin 116 passes through the stepped groove. The cylinder 115 is fixedly arranged in the mounting groove 117, and the elastic metal contact 113 contacts the inner wall of the cylinder 115.

[0048] The elastic metal contact 113 and the signal pin are connected together by welding.

[0049] Furthermore, the elastic metal contact 113 includes a connecting sleeve 118 and a plurality of metal springs 119 disposed on the connecting sleeve 118 . The metal springs 119 are disposed obliquely and in close contact with the inner wall of the metal cylinder 114 .

[0054] Furthermore, in actual use, a first mounting hole 125 is provided on the mounting shell 104, and a first cylinder 124 is provided inside the mounting shell 104. After the first cylinder 124 is connected to the mounting shell 104, an inner concave structure is formed, and the second clearance hole 112 is provided at the end of the first cylinder 124. Such a setting can hide the nut 108 and reduce the possibility of accidental contact, while avoiding affecting the connection between the metal cylinder 114 and the PCB board, thereby reducing the overall volume of the connector and shortening the length of the metal cylinder 114.

[0055] In some preferred implementation cases, a mounting seat 126 is provided under the support plate 102, and the mounting seat 126 has a spherical groove 127. The end of the bolt 106 is provided with a spherical portion 128 matching the spherical groove 127. The bolt 106 passes through the base so that when the bolt 106 floats between the mounting shell 104 and the male end body 101, the bolt 106 can tilt; by cooperating with the spherical groove 127, the spherical portion 128 and the spherical groove 127 can always maintain a close contact state with the spherical portion 128 under the action of the spring 109.

[0056] Furthermore, in actual use, a first spherical groove 129 connected to the second clearance hole 112 is provided on the first cylinder 124, and the upper end of the guide head 107 has a first spherical surface 130 matching the first spherical groove 129; this can make the bolt 106 more stable when floating occurs, further improving the floating performance.
