Technical Field

[0001] The present invention relates to the technical field of electrical connection, and in particular to a floating electrical connector applicable to automobiles and other occasions and a first connector thereof. Background Art

[0002] As is known to all, electrical connectors are widely used in electronic products to realize electrical connection between electronic components and meet the requirements of charging and discharging or data transmission.

[0003] Among them, for the electrical connector used in the automobile, it includes a plug and a socket that are plugged in and out. Through the plug-in cooperation of the plug and the socket, electrical contact between the terminals in the plug and the socket is achieved, thereby meeting the needs of charging or data transmission.

[0004] However, in the existing electrical connector plug, since the connection point on the plug for connecting to the outside world is fixed, there are defects such as relatively difficult and time-consuming assembly, relatively high requirements for the precision of the connector, and poor stability and reliability.

[0005] Therefore, there is an urgent need for a floating electrical connector and a first connector thereof to overcome one or more of the above-mentioned defects. Summary of the invention

This design makes the connection point (i.e., the floating connector) used to connect the first insulating body to the outside world not fixed but floating, so the stress at the connection point can be reduced to improve stability and reliability. At the same time, through adaptive floating adjustment, tolerances in different directions can be absorbed and corrected, which can reduce the difficulty and time of subsequent assembly.

[0011] Preferably, one end of the floating connector has a first limiting structure, the other end of the floating connector has a second limiting structure, and the first insulating body is limited between the first limiting structure and the second limiting structure along the penetration direction.

[0012] Preferably, the floating connector includes a cylinder inserted into the first insulating body and a sleeve ring connected to the cylinder, the first limiting structure is connected to the cylinder, the first limiting structure also protrudes laterally from the cylinder, part or all of the sleeve ring is formed on the second limiting structure, the second limiting structure also protrudes laterally from the cylinder, and the connecting hole is located in the cylinder.

[0013] Preferably, the floating connectors are respectively arranged at the corners of the first insulating body; both sides of the first insulating body separated along the penetration direction are provided with sunken sinking spaces, and the floating connectors are also located in the sinking spaces.

[0014] Preferably, the first insulating body has an outwardly protruding plug connector extending along the insertion direction, and the first terminal extends into the plug connector and is exposed to the outside through the plug connector.

[0015] Preferably, the first terminal is one or a plurality of first terminals arranged apart from each other, the plug connector is provided with first cavities whose number is at least the same as the first terminals and which are separated from each other, and each first terminal is partially suspended in a corresponding first cavity.

[0016] Preferably, a water leakage hole is also provided on the plug connector, and each of the first cavities is connected to the water leakage hole.

[0017] Preferably, a cavity bottom wall of the first cavity has a raised convex ring structure arranged around the first terminal.

[0018] Preferably, the first connector of the present invention further comprises an electrode terminal assembled on the first insulating body and extending into the plug connector, and the electrode terminal is also arranged separately from the first terminal; a second cavity is also provided on the plug connector and is arranged separately from the first cavity, and the electrode terminal is partially suspended in the second cavity.

[0019] To achieve the above-mentioned purpose, the floating electrical connector of the present invention comprises a second connector and the aforementioned first connector, wherein the first connector is plug-matched with the second connector.

[0020] Compared with the prior art, with the floating connector inserted in the first insulating body and capable of floating relative to the first insulating body within a preset range, a connection hole is provided in the floating connector for external connectors to pass through so as to connect the first insulating body to the outside world. This design makes the connection point (i.e., the floating connector) used to connect the first insulating body to the outside world not fixed but floating, so the stress at the connection point can be reduced to improve stability and reliability. At the same time, through adaptive floating adjustment, tolerances in different directions can be absorbed and corrected, which can reduce the difficulty and time of subsequent assembly.

[0029] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0030] See also Figure 1 and Figure 2 The floating electrical connector 100 of the present invention includes a first connector 10 and a second connector 20 . The first connector 10 and the second connector 20 are plugged together to meet the pluggable and unpluggable operation requirements between the first connector 10 and the second connector 20 .

[0031] Recombination Figure 6 The first connector 10 includes a first insulating body 11, a first terminal 12 mounted on the first insulating body 11, and a floating connector 13 inserted into the first insulating body 11. The floating connector 13 can float relative to the first insulating body 11 within a preset range to meet the need for fine-tuning of the floating connector 13 relative to the first insulating body 11. The floating connector 13 is provided with a connecting hole 131 for external connectors (such as but not limited to screws or bolts) to pass through to connect the first insulating body 11 to the outside world, so that the external connector passing through the connecting hole 131 can achieve the purpose of reducing the stress at the connection point and absorbing and correcting the tolerances in different directions by fine-tuning the floating connector 13 relative to the first insulating body 11. Specifically, in Figure 6 As an example, the floating direction of the floating connector 13 includes a first direction intersecting with the insertion direction of the floating connector 13 (as indicated by arrow A) and a second direction parallel to the insertion direction, so as to meet the need for fine-tuning the floating connector 13 relative to the first insulating body 11 in multiple directions; optionally, the first direction is perpendicular to the insertion direction, in which case the first direction may be the radial direction of the connection hole 131, so that the floating connector 13 may be fine-tuned relative to the first insulating body 11 in more directions; obviously, according to actual needs, the first direction may also be a single direction perpendicular to the insertion direction, for example Figure 6 The up and down direction perpendicular to the direction indicated by arrow A, or Figure 6 The front-to-back direction perpendicular to the direction indicated by arrow A, etc.

[0032] The floating distance of the floating connector 13 in the first direction is Figure 6 The floating distance of the floating connector 13 in the second direction is Figure 6 The size of D1 is such that the preset range of the floating connector 13 includes the floating distance in the first direction and the floating distance in the second direction. Figure 6 It is shown that the floating direction of the floating connector 13 includes the first direction and the second direction. Obviously, according to actual needs, the floating direction of the floating connector 13 can also include only the first direction. Figure 6 More specifically, as follows:

[0033] like Figure 1 , Figure 2 and Figure 6 As shown, as an example, one end of the floating connector 13 has a first limiting structure 132, and the other end of the floating connector 13 has a second limiting structure 133. The first insulating body 11 is limited between the first limiting structure 132 and the second limiting structure 133 along the penetration direction. Figure 6 As shown; the first limiting structure 132 and the second limiting structure 133 are used to limit the floating distance of the floating connector 13 relative to the first insulating body 11 in the second direction, thereby effectively preventing the floating connector 13 from accidentally falling off from the first insulating body 11. Specifically, Figure 6 As an example, the floating connector 13 includes a cylinder 134 inserted into the first insulating body 11 and a sleeve ring connected to the cylinder 134. The first limiting structure 132 is connected to the cylinder 134. The first limiting structure 132 also protrudes laterally from the cylinder 134. Optionally, as an example, the first limiting structure 132 and the cylinder 134 form an integrated structure to simplify the manufacturing process of the first limiting structure 132 and the cylinder 134. Obviously, according to actual needs, the first limiting structure 132 and the cylinder 134 can also be independent components, and then they are fixed together by gluing, welding, etc. The entirety of the sleeve ring is formed on the second limiting structure 133, that is, the sleeve ring and the second limiting structure 133 are the same thing at this time, so the number 133 can also be represented as a sleeve ring; and the second limiting structure 133 also protrudes laterally from the cylinder 134, the state is shown in FIG. Figure 6 As shown; correspondingly, the connection hole 131 is located in the cylinder 134. Therefore, with the cooperation of the cylinder 134 and the sleeve ring, the installation operation of the floating connector 13 on the first insulating body 11 is facilitated. More specifically, when the entire sleeve ring forms the second limiting structure 133, the sleeve ring and the cylinder 134 can be installed by gluing or welding. It should be noted that according to actual needs, part of the sleeve ring can also form the second limiting structure 133, so it is not necessary to Figure 6 The limit shown is as follows; in addition, although Figure 6 The floating connector 13 includes a cylinder 134 and a sleeve ring. Obviously, according to actual needs, the floating connector 13 can also be a single component, such as a rivet cap. In this case, the process of assembling the rivet cap on the first insulating body 11 is as follows: firstly, the end of the rivet cap without a cover is passed through the first insulating body 11, and then the end is riveted to obtain the second limiting structure 133, and the cover of the rivet cap forms the first limiting structure 132 accordingly. Figure 6 Limits shown.

[0034] In order to make the connection between the first insulating body 11 and the outside more reliable, Figures 1 to 5 and Figure 7 As an example, the floating connectors 13 are respectively arranged at the corners of the first insulating body 11, such as but not limited to the four corners of the first insulating body 11; obviously, according to actual needs, the floating connectors 13 can also be arranged at the two opposite sides or adjacent sides of the first insulating body 11, so it is not necessary to Figures 1 to 5 and Figure 7 In addition, both sides of the first insulating body 11 separated along the penetration direction are provided with a sunken sinking space 111, and the floating connector 13 is also located in the sunken space 111 to prevent the floating connector 13 from protruding from the first insulating body 11 along the penetration direction.

[0035] like Figures 2 to 3 as well as Figures 5 to 7 As shown in FIG. 1 , as an example, the first insulating body 11 has a protruding plug connector 112 extending in the insertion direction, and the first terminal 12 extends into the plug connector 112 and is exposed to the outside by the plug connector 112; the plug connector 112 facilitates the plugging operation between the first connector 10 and the second connector 20. Specifically, Figure 3 , Figure 5 and Figure 7 As an example, the number of the first terminals 12 is four and is separated from each other. Obviously, according to actual needs, the number of the first terminals 12 can also be one, two or three. Figure 3 , Figure 5 and Figure 7 In addition, the plug connector 112 is provided with the same number of first cavities 112a as the first terminals 12 and separated from each other, and each first terminal 12 is partially suspended in a corresponding first cavity 112a, and the first cavity 112a restrains the water that accidentally penetrates, thereby preventing the water that accidentally penetrates from causing a short circuit and electrolysis in the first connector 10. More specifically, Figure 7 As an example, a water leakage hole 112b is further provided on the plug connector 112, and each first cavity 112a is connected to the water leakage hole 112b, so that water accidentally seeping into the first cavity 112a can be discharged outward with the help of the water leakage hole 112b, so as to more effectively prevent the first connector 10 from short circuiting and electrolysis; in addition, a raised convex ring structure 1122 arranged around the first terminal 12 is provided on the cavity bottom wall 1121 of the first cavity 112a, so that with the help of the convex ring structure 1122, water flowing from the first cavity 112a to the first terminal 12 can be blocked, so as to more effectively prevent the first connector 10 from short circuiting and electrolysis.

[0036] In order to facilitate the correct plugging and unplugging operation of the first connector 10 and the second connector 20, Figure 5 and Figure 7As an example, a corresponding numerical mark is marked in the first cavity 112a where each first terminal 12 is located. In addition, the first connector 10 also includes an electrode terminal 14 assembled on the first insulating body 11 and extending into the plug connector 112, and the electrode terminal 14 is also arranged separately from the first terminal 12; at this time, the plug connector 112 is also provided with a second cavity 112c arranged separately from the first cavity 112a, and the electrode terminal 14 is partially suspended in the second cavity 112c, so as to restrain the infiltrated water with the help of the second cavity 112c, effectively preventing the first connector 10 from short circuiting and electrolysis; optionally, in Figure 5 and Figure 7 As an example, there are two electrode terminals 14, and corresponding positive and negative marks are marked in the second cavity 112c where each electrode terminal 14 is located. Figure 5 and Figure 7 Obviously, according to actual needs, the number of electrode terminals 14 can also be other numbers, so it is not necessary to Figure 5 and Figure 7 Limits shown.

[0037] like Figure 8 As shown, since the second connector 20 is plugged into the first connector 10, the structure of the second connector 20 matches the first connector 10. Figure 8 In the figure, the second connector 20 comprises a second insulating body 21, second terminals 22 mounted on the second insulating body 21 and matching the number of the first terminals 12, and electrode terminals 23 mounted on the second insulating body 21 and matching the number of the electrode terminals 14 of the first connector 10. The second insulating body 21 is provided with a plug-in cavity 211 for the plug connector 112 to be plugged in and matched, the second terminal 22 and the electrode terminal 23 are partially suspended in the plug-in cavity 211; and the plug-in cavity 211 is provided with a plug-in body 212 embracing the second terminal 22 and a plug-in body 213 embracing the electrode terminal 23, the state is shown in FIG. Figure 8 As shown. Therefore, after the second connector 20 is plugged into the first connector 10, the plug connector 112 is inserted into the plug cavity 211, the surrounding plug body 211 is inserted into the first cavity 112a, and the surrounding plug body 213 is inserted into the second cavity 112c. The second terminal 22 is in electrical contact with the first terminal 12, and the electrode terminal 23 is in electrical contact with the electrode terminal 14. In addition, in order to make the plug connector 112 and the plug cavity 211 seal, a sealing ring 15 is provided on the plug connector 112. Figure 2 , Figure 3 and Figure 6 shown.

[0038] Compared with the prior art, with the floating connector 13 inserted into the first insulating body 11 and capable of floating relative to the first insulating body 11 within a preset range, a connection hole 131 is provided in the floating connector 13 for external connectors to pass through so as to connect the first insulating body 11 to the outside world. This design makes the connection point (i.e., the floating connector 13) used to connect the first insulating body 11 to the outside world not fixed but floating, so the stress at the connection point can be reduced to improve stability and reliability. At the same time, through adaptive floating adjustment, tolerances in different directions can be absorbed and corrected, which can reduce the difficulty and time of subsequent assembly.

[0039] It is to be noted that the first cavity 112a and the second cavity 112c are separated from each other, which means that they are not connected to each other. Figure 3 , Figure 4 and Figure 7 It is shown that the number of the first cavities 112a is the same as the number of the first terminals 12. Obviously, according to actual needs, the number of the first cavities 112a can also be greater than the number of the first terminals 12. In addition, the leak holes 112b are exposed to the outside from the side of the plug connector 112. Finally, the first connector 10 can be called a male connector, and correspondingly, the second connector 20 is a female connector.

[0040] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
