Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical connectors, in particular to a floating connector and a combination thereof. BACKGROUND

[0002] Chinese utility model patent CN211829282U discloses a floating connector, which comprises a sliding main body, an insulator, an inner conductor and an outer conductor. The inner conductor is arranged at the center of the sleeve shaft of the sliding main body through the insulator. The outer conductor is slidably sleeved on the outer circumference of the sleeve and keeps contact and conduction with the sleeve. The inner conductor comprises a fixed terminal and a movable pin. The fixed terminal is fixedly connected with the insulator. The movable pin is coaxially arranged at one end of the fixed terminal and keeps contact and conduction with the fixed terminal. The sliding main body is fixed with an outer spring sheet connected with the outer wall of the outer conductor on the outer circumference of the sleeve.

[0003] The connector keeps contact and conduction through the sliding contact of the outer conductor and the sleeve and the coaxial contact of the movable pin and the fixed terminal. When the PCB board on one side of the connector is axially deviated due to force, the connector always keeps conduction to ensure the stability of signal transmission. However, in this scheme, if the PCB board is inclined due to force and is radially deviated perpendicular to the axial direction of the connector, the outer conductor and the sleeve are prone to sliding jamming, and the fixed terminal fixed in the insulator cannot keep good electrical connection with another connector when having radial deviation. In addition, the floating connector introduces the outer spring sheet, which makes the assembly and structure of the design more complex. Therefore, the floating connector still needs to be further improved. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the deficiencies of the prior art and provide a floating connector that can keep good electrical connection in a vibrating environment and a combination thereof.

[0005] The technical solution adopted by the present application is as follows:

[0006] According to one aspect of the present application, a floating connector is provided, comprising: a center conductive structure including a main body, a contact pin movably mounted at the front of the main body, and a center spring mounted between the contact pin and the main body; a rear portion of the main body is provided with a mating cavity, and the mating cavity is provided with an elastic mating portion capable of being elastically deformed in a radial direction perpendicular to the front-rear direction; an insulating body surrounding the outer periphery of the center conductive structure; and an outer conductive structure including a first conductive shell provided at the outer periphery of the insulating body, a second conductive shell movably sleeved at the outer periphery of the insulating body, and an outer spring located between the first conductive shell and the second conductive shell; the second conductive shell is located inside the first conductive shell, at least one of the first conductive shell and the second conductive shell is provided with an elastic contact arm, and the first conductive shell and the second conductive shell are kept in electrical contact through the elastic contact arm.

[0007] According to another aspect of the present application, a floating connector assembly is provided, comprising a floating connector as described above and a cable connector plugged at the rear of the floating connector, the cable connector including a center conductive pin, a cable seal sleeved at the outer periphery of the center conductive pin, a shell further sleeved at the outer periphery of the cable seal, and a cable electrically connected to the rear of the center conductive pin and the shell; the center conductive pin is plugged into the mating cavity of the floating connector and is in contact with the elastic mating portion; the shell is sleeved at the outer periphery of the first conductive shell of the floating connector.

[0008] Compared with the prior art, the floating connector of the present application has at least the following advantages: the center conductive structure has a contact pin capable of being elastically slid in the front-rear direction and an elastic mating portion capable of being elastically deformed in the radial direction perpendicular to the front-rear direction at the rear of the main body, so that the electrical contact of the center can be maintained when the center is deformed in the front-rear direction and the radial direction; the outer conductive structure has a first conductive shell and a second conductive shell capable of being elastically slid in the front-rear direction, and the first conductive shell and the second conductive shell can maintain electrical contact when they are relatively inclined through the elastic contact arm, so that the electrical contact of the outer periphery can be maintained when the outer periphery is deformed in the front-rear direction and the radial direction; thus, the floating connector can maintain good electrical connection in a vibrating environment and improve the stability of electrical contact. At the same time, the present application avoids introducing a separate outer spring, simplifying the structure and assembly steps. BRIEF DESCRIPTION OF DRAWINGS

[0044] Although the invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the invention and is not intended to limit the invention to what is described herein.

[0045] Therefore, a feature pointed out in this specification is used to illustrate one feature of one embodiment of the invention, and does not imply that every embodiment of the invention must have the described feature. Furthermore, it should be noted that this specification describes many features. While certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0046] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of the invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0047] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0048] See Figures 1 to 5 A preferred embodiment of the present invention provides a floating connector assembly 100, which includes a floating connector 1 and a cable connector 2 inserted behind the floating connector 1.

[0049] The floating connector assembly 100 can be installed inside a camera module 500 during use and electrically connected to a circuit board 700 installed inside the camera module 500. The camera module 500 has a receiving cavity 501 with a front opening, and a terminal 502 extends rearward from the camera module 500. The circuit board 700 is housed within the receiving cavity 501. An electronic device 701 is located on the front surface of the circuit board 700, and an electrical connector 702 is located on the rear surface of the circuit board 700. The electrical connector 702 and the electronic device 701 are electrically connected to each other through circuitry formed on the circuit board 700. Preferably, the electronic device 701 is a camera image sensor chip. The camera module 500 can be installed in a vehicle to form an in-vehicle camera assembly. Accordingly, the floating connector assembly 100 will operate in a vibrating environment along with the camera module 500.

[0050] The floating connector assembly 100 extends into the receiving cavity 501 via the terminal 502. The front end of the floating connector 1 is electrically connected to the electrical connector 702. The cable connector 2 extends from the rear end of the terminal 502 and connects to an external electronic device (not shown). Thus, signal transmission between the electronic device 701 and the external electronic device is realized through the floating connector assembly 100.

[0051] See Figures 6 to 8 The floating connector 1 includes a central conductive structure 11, an insulating body 12 surrounding the outer periphery of the central conductive structure 11, and an outer conductive structure 13 disposed on the outer periphery of the insulating body 12.

[0052] See Figure 9 In this preferred embodiment, the central conductive structure 11 includes a main body 111, a contact needle 112, a central spring 113, a sleeve 114, and a crown spring 115.

[0053] Combination Figures 6 to 9 The contact pin 112 is movably mounted in front of the main body 111, and the central spring 113 is housed between the front part of the main body 111 and the rear part of the contact pin 112. The two ends of the central spring 113 elastically abut against the main body 111 and the contact pin 112 respectively, so that the contact pin 112 can elastically move back and forth relative to the main body 111.

[0054] The sleeve 114 is fitted around the outer periphery of the body 111. Multiple rear claws 1141 extend rearward from the rear end of the sleeve 114, engaging with the outer periphery of the body 111. Multiple front claws 1142 extend forward from the front end of the sleeve 114, elastically abutting against the outer peripheral wall of the contact pin 112. These front claws 1142 maintain contact with the contact pin 112 as the contact pin 112 moves back and forth. The sleeve 114 enhances the conductive contact between the body 111 and the contact pin 112, improving the electrical connection reliability of the central conductive structure 11.

[0055] The crown spring 115 has two cylindrical portions 1151 spaced apart front to back and a plurality of spring plates 1152 connected between the two cylindrical portions 1151. These spring plates 1152 are uniformly arranged in a cage shape along the circumference of the cylindrical portions 1151. The crown spring 115 can be stamped from highly elastic beryllium bronze strip.

[0056] In this preferred embodiment, the rear of the main body 111 is provided with a docking cavity 1111, and the crown spring 115 is installed in the docking cavity 1111. The cylindrical portion 1151 is fitted against the inner wall of the docking cavity 1111, and the spring piece 1152 protrudes inward into the docking cavity 1111. Each spring piece 1152 is arc-shaped, protruding centrally into the docking cavity 1111, and can elastically deform in a radial direction perpendicular to the front-back direction, forming an elastic docking portion. The space enclosed by the plurality of spring pieces 1152 allows the cable connector 2 to be inserted therein and provides an electrical connection.

[0057] See Figure 7 and Figure 8 The insulating body 12 includes a base 121 and a column 122 extending forward from the base 121. Both the base 121 and the column 122 are generally cylindrical in shape, and the outer diameter of the base 121 is larger than the outer diameter of the column 122.

[0058] The outer side of the base 121 is provided with a stop groove 1212, which passes through the front end face of the base 121. The interior of the base 121 is provided with two receiving grooves 1211 that pass through each other from front to back, and the two receiving grooves 1211 are symmetrically located on both sides of the column 122.

[0059] The outer surface of the column 122 is provided with two sliding grooves 1221 extending front and rear. In this embodiment, the sliding grooves 1221 are connected to the receiving groove 1211. In other embodiments, the sliding grooves 1221 may also be circumferentially spaced from the receiving groove 1211.

[0060] The insulating body 12 has a through mounting hole 1201 at its center, thus surrounding the outer periphery of the central conductive structure 11. (See reference...)Figure 6 The central conductive structure 11 is installed in the mounting hole 1201. The main body 111 of the central conductive structure 11 extends slightly backward beyond the seat 121 of the insulating body 12, and the contact pin 112 of the central conductive structure 11 extends forward beyond the column 122 of the insulating body 12.

[0061] like Figure 6 As shown, the external conductive structure 13 includes a first conductive shell 131, a second conductive shell 132, and an external spring 133.

[0062] Combination Figures 6 to 8 The first conductive housing 131 is generally cylindrical, with its rear end firstly bent inward and then forward to extend into two sheet-like first contact arms 1311, which cantilever into the interior of the first conductive housing 131. Near the rear end, the side wall of the first conductive housing 131 has an opening and a stop tab 1312 protruding inward from the opening. A plurality of outwardly protruding mounting tabs 1313 are circumferentially arranged in the middle of the first conductive housing 131, protruding outward from the opening in the middle of the side wall of the first conductive housing 131.

[0063] The first conductive housing 131 is sleeved on the outer periphery of the base 121, and the two first contact arms 1311 are respectively received in the two receiving grooves 1211. The stop protrusion 1312 can extend into the stop groove 1212, thereby preventing the first conductive housing 131 from being dislodged from the base 121.

[0064] Continue reading Figures 6 to 8 The second conductive housing 132 is cylindrical, with two cantilevered second contact arms 1321 extending rearward from its rear end. The two second contact arms 1321 are symmetrically arranged. Each second contact arm 1321 has an outwardly protruding elastic contact point 1322 at its end.

[0065] The second conductive housing 132 has two inwardly protruding sliding tabs 1323 in the middle, with the two sliding tabs 1323 spaced apart and facing each other. The sliding tab 1323 is a spring-loaded structure that protrudes inward from the side wall of the second conductive housing 132, and the sliding tab 1323 is capable of elastic deformation in the radial direction.

[0066] The second conductive housing 132 is further provided with a plurality of outwardly protruding limiting protrusions 1324 in front of the sliding protrusion 1323, and these limiting protrusions 1324 are evenly distributed along the circumference of the second conductive housing 132.

[0067] The front end of the second conductive housing 132 bends out to form a plurality of mating pieces 1325 extending radially inward. These mating pieces 1325 are generally located on a plane perpendicular to the front-back direction, and there are gaps between the plurality of mating pieces 1325.

[0068] Main references Figure 6 The second conductive housing 132 is fitted around the outer periphery of the column 122 and can move back and forth relative to the column 122. The second conductive housing 132 extends forward beyond the first conductive housing 131. Two sliding protrusions 1323 respectively extend into the two sliding grooves 1221, and the sliding protrusions 1323 can move back and forth along the sliding grooves 1221, thereby guiding and limiting the back and forth movement of the second conductive housing 132.

[0069] Two second contact arms 1321 extend rearward into the two receiving slots 1211 of the base 121, and the elastic contact point 1322 of each second contact arm 1321 elastically abuts against the corresponding first contact arm 1311. When the second conductive housing 132 moves back and forth, the second contact arm 1321 slides back and forth relative to the first contact arm 1311, and the second contact arm 1321 and the first contact arm 1311 always maintain elastic abutment, so that the second conductive housing 132 and the first conductive housing 131 always maintain electrical contact.

[0070] When the second conductive housing 132 is tilted relative to the first conductive housing 131, the second contact arm 1321 can elastically deform to swing radially, still elastically abutting against the first contact arm 1311. Additionally, the sliding tab 1323 can also elastically deform to allow the second conductive housing 132 to tilt relative to the insulating body 12 as a whole, and in this state, the second conductive housing 132 can still move smoothly back and forth relative to the insulating body 12.

[0071] It should be noted that in this preferred embodiment, the second contact arm 1321 extends in a cantilevered manner along the front-rear direction and can elastically deform to form an elastic contact arm. The elastic deformation of the second contact arm 1321 allows the second conductive housing 132 to maintain electrical contact with the first conductive housing 131 in a vibration environment. In other embodiments not shown, an elastic contact arm may also be provided on the first conductive housing 131. For example, the first contact arm 1311 may be configured to elastically deform and elastically abut against the second conductive housing 132. Alternatively, the first conductive housing 131 and the second conductive housing 132 may each be provided with an elastic contact arm to elastically abut against each other. In summary, the first conductive housing 131 and the second conductive housing 132 maintain electrical contact through the elastic contact arm.

[0072] Continue readingFigure 6 The outer spring 133 is located between the first conductive housing 131 and the second conductive housing 132. Specifically, the outer spring 133 is sleeved on the outer periphery of the second conductive housing 132. The front end of the outer spring 133 elastically abuts against the limiting protrusion 1324 on the second conductive housing 132, and the rear end of the outer spring 133 elastically abuts against the seat 121 of the insulating body 12. According to the elastic deformation of the outer spring 133, the second conductive housing 132 and the first conductive housing 131 are allowed to move back and forth and tilt radially under the action of external force, and elastically return to their positions after the external force is removed.

[0073] The assembly process of the floating connector 1 is roughly as follows: assembling the central conductive structure 11, inserting the central conductive structure 11 from back to front into the integrally injection molded insulating body 12, then fitting the first conductive shell 131 onto the seat 121 of the insulating body 12, and finally fitting the second conductive shell 132, on which the outer spring 133 is fitted, onto the column 122 of the insulating body 12 from front to back.

[0074] See Figures 10 to 12 The preferred embodiment of the cable connector 2 includes a central conductive pin 21, a cable seal 22 sleeved on the outer periphery of the central conductive pin 21, a housing 23 further sleeved on the outer periphery of the cable seal 22, a cable 24 electrically connected to the rear of the central conductive pin 21 and the housing 23, and an inner insulating seat 25 sleeved on the front end of the cable seal 22.

[0075] The central conductive needle 21 includes a needle-shaped central docking portion 211 and a generally cylindrical syringe portion 212 located behind the central docking portion 211.

[0076] The cable seal 22 has a stepped structure, including a rear sealing portion 221 with a larger outer diameter and a front sealing portion 222 with a smaller outer diameter extending forward from the rear sealing portion 221. The cable seal 22 has a through hole 223 in the center, which extends from the front to the back.

[0077] The front sealing part 222 is provided with a plurality of first sealing ribs 224 protruding inward on the inner wall of the through hole 223. These first sealing ribs 224 are arranged around the circumference of the through hole 223, and the plurality of first sealing ribs 224 are arranged at intervals along the axial direction of the through hole 223.

[0078] The outer peripheral wall and rear end face of the rear sealing part 221 each protrude a second sealing rib 225 outward. The second sealing rib 225 is annular and is arranged around the axis of the through hole 223.

[0079] The cable seal 22 is fitted around the outer periphery of the syringe portion 212 of the central conductive needle 21 through the through hole 223, while the central mating portion 211 of the central conductive needle 21 extends forward from the cable seal 22. The first sealing rib 224 surrounds the syringe portion 212 in a sealing manner, and the first sealing rib 224 is compressed by the syringe portion 212 to form a sealing effect between the cable seal 22 and the central conductive needle 21.

[0080] The housing 23 includes a receiving tube portion 231 with an opening at the front end and a cable connection portion 232 extending rearward from the receiving tube portion 231. Both the receiving tube portion 231 and the cable connection portion 232 are cylindrical in shape, and the outer diameter of the receiving tube portion 231 is larger than the outer diameter of the cable connection portion 232.

[0081] The receiving cylinder 231 is fitted around the outer periphery of the rear sealing portion 221 of the cable seal 22. The inner peripheral wall of the receiving cylinder 231 is pressed against the second sealing rib 225 protruding from the outer peripheral wall of the rear sealing portion 221. The rear wall of the receiving cylinder 231 is pressed against the second sealing rib 225 protruding from the rear end face of the rear sealing portion 221 to form a waterproof seal.

[0082] The inner insulating seat 25 is fitted around the outer periphery of the front sealing portion 222 of the cable seal 22. When subjected to a rearward external force, the inner insulating seat 25 presses the cable seal 22 backward, thereby causing the second sealing rib 225 to fit tightly with the outer shell 23 to form a reliable sealing effect.

[0083] The cable 24 has a core conductor 241 located at the center, an outer conductor 242 surrounding the core conductor 241, an insulation layer 243 separating the core conductor 241 and the outer conductor 242, and an insulation outer sheath 244 covering the outermost periphery.

[0084] The front end of the core conductor 241 is inserted into the syringe portion 212 of the central conductive needle 21 to form a conductive connection. The outer conductor 242 is fitted and fixed to the cable connection portion 232 of the outer casing 23 to form a grounding connection.

[0085] In the cable connector 2 of this embodiment, a first sealing connection is formed between the first sealing rib 224 and the central conductive pin 21, and a second sealing connection is formed between the second sealing rib 225 and the outer shell 23, which can prevent moisture entering from the cable 24 from being transmitted forward, thus achieving a sealing effect.

[0086] Furthermore, the connection between the cable 24 and the cable connector 232 can be further coated with adhesive by applying glue to enhance waterproofing.

[0087] Based on the above description of the structure of each part of the floating connector assembly 100, please refer to...Figure 3 The front end of the cable connector 2 is inserted into the rear end of the floating connector 1, and the front end of the floating connector 1 mates with the electrical connector 702. In addition, the mounting spring 1313 on the first conductive housing 131 of the floating connector 1 abuts against the rear wall of the receiving cavity 501, and the front end of the outer shell 23 of the cable connector 2 abuts against the front wall of the terminal 502, thereby positioning and installing the floating connector assembly 100 in the camera module 500.

[0088] In this design, the central conductive pin 21 of the cable connector 2 is inserted into the mating cavity 1111 of the central conductive structure 11 of the floating connector 1. The central mating portion 211 of the central conductive pin 21 is in electrical contact with the crown spring 115 of the central conductive structure 11, and the contact pin 112 of the central conductive structure 11 elastically abuts against the center of the electrical connector 702, thereby establishing a conductive connection between the electrical connector 702 and the cable 24. Since the contact pin 112 can elastically slide relative to the body 111 in the front-back direction, and the crown spring 115 can elastically deform in the radial direction perpendicular to the front-back direction, the conductive connection can be maintained under vibration conditions even when the electrical connector 702, the central conductive structure 11, and the central conductive pin 21 deform relative to each other in the front-back and radial directions through these elastic sliding and elastic deformations.

[0089] The outer shell 23 of the cable connector 2 is fitted around the outer periphery of the outer conductive structure 13 of the floating connector 1. The receiving tube portion 231 of the outer shell 23 is connected to the first conductive shell 131 of the outer conductive structure 13. The second conductive shell 132 of the outer conductive structure 13 elastically abuts against the electrical connector 702, thereby establishing a grounding connection from the electrical connector 702 to the cable 24. Since the second conductive shell 132 and the first conductive shell 131 can maintain electrical contact during sliding back and forth and tilting docking through the second contact arm 1321 and the first contact arm 1311, the reliability of the grounding connection can be maintained under vibration.

[0090] Therefore, signal transmission between the circuit board 700 and external electronic devices can be achieved through this floating connector assembly 100, and good electrical connection can be maintained in vibration environments, improving the stability of electrical contact. At the same time, based on the structure of this floating connector 1, the introduction of a separate external spring can be avoided, simplifying the structure and assembly steps.

[0091] Figure 13 The diagram illustrates a cross-sectional view of a floating connector 4 according to another preferred embodiment of the present invention. This floating connector 4 also includes a central conductive structure 41, an insulating body 42, and an outer conductive structure 43. The main difference between this floating connector 4 and the floating connector 1 of the previous embodiment lies in the different central conductive structure 41.

[0092] Combination Figure 13 and Figure 14 The central conductive structure 41 includes a main body 411, a contact needle 412 and a central spring 413, but does not have a sleeve or crown spring.

[0093] The main body 411 is a structure formed by integral stamping and bending of a metal sheet. The rear part of the main body 411 is provided with a docking cavity 4111. The side wall of the rear part of the main body 411 is provided with an opening and bends towards the docking cavity 4111 to form a plurality of elastic docking parts 4112. The elastic docking parts 4112 can undergo elastic deformation in the radial direction perpendicular to the front and rear direction, thereby allowing the central conductive pin 21 of the cable connector 2 to be docked at an angle.

[0094] The front end of the main body 411 extends forward with multiple elastic claws 4113, which elastically abut against the contact pin 412 to strengthen the electrical connection between the main body 411 and the contact pin 412.

[0095] Corresponding to the central conductive structure 41, the mounting hole 4201 of the insulating body 42 has been adapted to securely accommodate the central conductive structure 41.

[0096] Other technical features of the floating connector 4 can be referred to the floating connector 1 of the previous embodiment, and will not be repeated here.

[0097] Figures 15 to 17 The diagram illustrates the structure of a cable connector 6 according to another preferred embodiment of the present invention. The cable connector 6 includes a central conductive pin 61, a cable seal 62, a housing 63, and a cable 64. Compared to the cable connector 2 of the previous embodiment, the cable connector 6 does not have an inner insulating base, but instead includes a sealant 66 covering the outer periphery of the connection between the housing 63 and the cable 64.

[0098] The housing 63 has a frustoconical conical shell 633 between its receiving tube portion 631 and cable connection portion 632. The conical shell 633 has at least one through-hole 635 communicating with the inside and outside of the housing 63. The conical shell 633 and the cable connection portion 632 are fitted together around the outer periphery of the cable seal 62. The cable seal 62 does not have sealing ribs.

[0099] The sealant 66 covers the outer periphery of the connection between the housing 63 and the cable 64. Specifically, the sealant 66 covers the rear half of the conical shell portion 633, the entire cable connection portion 632, and the front end of the insulating outer sheath 644 of the cable 64. Furthermore, the sealant 66 enters the interior of the housing 63 through the adhesive passage 635 to cover the cable sealant 62 within it.

[0100] The sealant 66 located on the outside of the housing 63 seals the gap between the housing 63 and the cable 64. The sealant 66 located inside the housing 63 can seal the gap between the cable seal 62 and the central conductive pin 61, thereby preventing external moisture from entering the cable 64 and preventing moisture from being transmitted forward from the cable 64, achieving a sealing and waterproof effect.

[0101] Other technical features of the cable connector 6 can be referred to the cable connector 2 of the previous embodiment, and will not be repeated here.

[0102] The above description is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention. Those skilled in the art can easily make corresponding modifications or alterations based on the main concept and spirit of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of protection claimed in the claims.
