Description

Technical Field

[0001] <Cross - Reference to Related Applications> This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on July 20, 2022, with the application number CN202210863702.7 and the invention title "Oscillating Offset - Tolerant Connector", and a Chinese patent application filed with the Chinese Patent Office on October 30, 2022, with the application number CN202222871787.1 and the invention title "Oscillating Offset - Tolerant Floating Connector for Guiding Pairing of Conductive Terminals", and all of its content is incorporated herein by reference.

[0002] This application relates to the field of connector technology, and particularly to an oscillating offset - tolerant connector.

Background Art

[0003] The description herein only provides background information related to this application and does not necessarily constitute prior art.

[0004] With the rapid development of the communication industry and various electronic and electrical devices, connectors are widely applied to various circuits. A connector usually includes a housing made of insulating material and a plurality of terminals made of conductive material. Each terminal is provided on the connector housing, and the end of each terminal is electrically connected to a circuit board.

[0005] A conventional floating connector includes a fixed - side housing fixed on a circuit board, a floating - side housing that can be fitted to the fitting part of a mating connector, and contacts held across both the fixed - side housing and the floating - side housing. The floating - side housing is configured to be movable relative to the fixed - side housing by elastic deformation of the contacts so as to easily absorb the deviation between circuit boards or the deviation from the fitting position of the mating connector.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The defects of the conventional floating connector are as follows. 1. The floating principle of the conventional floating connector is that one side of the terminal is compressed and the corresponding terminal on the other side is extended. The movement of the floating part is a translation, and the offset allowance depends entirely on the interval space between the fixed base and the floating part. When a large offset allowance is required, it is necessary to increase the interval space, which increases the area occupied on the circuit board. 2. The conventional floating connector has limited adaptability to angular deviation. 3. In the conventional floating solution, since the entire floating part translates, all terminals are compressed and extended, and after its insertion is completed, the residual stress is large. 4. In the conventional floating solution, in a single circuit, the male terminal and the female terminal only contact on one side, and the reliability of withstanding a bad environment is weak.

Means for Solving the Problem

[0007] In order to achieve the above object, the present application discloses a swing-type offset tolerance connector including a fixed base, an insulator, and conductive terminals. The insulator is floatingly supported on the fixed base via the conductive terminals, and the conductive terminals are provided with flexible parts that floatingly support the translation and / or swing of the insulator.

[0008] By swinging together with the insulator, the conductive terminals of the swing-type offset tolerance connector can adapt to the deviation caused by the non-coaxiality and non-centering of the male connector and the female connector due to assembly errors, effectively ensuring the structural stability after the swing-type offset tolerance connector and the external insertion parts are inserted, and avoiding damage to the terminals and other parts of the swing-type offset tolerance connector and / or the external insertion parts due to insertion deviation during insertion. The structure is simple and easy to use.

[0009] The present application further provides a swing-type offset-tolerant floating connector for guiding the pairing of a pair of conductive terminals including a connector and an externally inserted component. The connector includes a floating insulator, and a plurality of insertion holes are provided in the floating insulator. A first conductive terminal is fixedly engaged in the insertion hole. The externally inserted component is provided with a second conductive terminal that can be inserted into the insertion hole and is inserted and connected to the first conductive terminal in a pluggable manner. The plurality of second conductive terminals correspond one-to-one to the plurality of first conductive terminals. An arc surface or an inclined surface guide structure is provided between the second conductive terminal and the insertion hole, which can be converted into an adjustment by pressing their interaction forces to float the floating insulator during fitting.

Advantages of the Invention

[0010] During the pairing process, the spherical crown structure at the upper end of the floating insulator guides the floating insulator into the concave groove at the lower end of the externally inserted component. The spherical crown structure can be movably fitted into the concave groove to realize relative sliding and swinging. Further, through the sliding fit between the inclined sliding guide surface and the sliding guide inclined surface, the sliding guide structure at the upper end of the insertion hole is a part of a through hole with a large outer port and a small inner port. A sliding guide inclined surface with a gradually decreasing inner diameter is provided between the upper end and the lower end of the through hole. An inclined sliding guide surface for guiding the tip of the insertion pin into the insertion hole is provided at the tip of the insertion pin to realize a sliding guide function during the pairing process. During the sliding process, the sliding guide structure is pressed by the sliding guide inclined surface and floats to one side, thereby realizing the conversion of the interaction force between them to press the floating insulator to float to one side. After the floating insulator floats and adjusts, the plurality of second conductive terminals can be smoothly inserted into the corresponding insertion holes in the axial direction. Even when the second conductive terminal and the insertion hole are in an eccentric state, the insertion pin can be guided to be smoothly inserted into the insertion hole, avoiding the defect that the insertion pin is easily broken due to eccentricity when fitting a circular mounting hole with a circular shaft insertion pin in the prior art. The structure is simple and the fitting stability is higher.

[0014] Note that the technical features of different embodiments of the present application described below can be combined with each other as long as there is no conflict between them.

[0015] As shown in FIGS. 1 to 18, a swing-type offset tolerance connector includes a fixed base 1, a conductive terminal 2, and an insulator 3. The conductive terminal 2 is divided into an insertion body 21, a flexible portion 22, and a terminal fillet 23 in order from top to bottom. The terminal fillet 23 is provided with a holding portion 24 that can be inserted into the fixed base 1. The insulator 3 is floatingly supported on the fixed base 1 via the insertion body 21, the flexible portion 22, and the holding portion 24.

[0016] In the present application, the function of the flexible portion 22 is to floatingly support the insulator on the fixed base via the conductive terminal by allowing the floating support insulator 3 to perform translational and / or swinging floating with respect to the fixed base 1, thereby facilitating stable fitting in the deviation state between the connector 100 and the external insertion component 200.

[0017] In an embodiment of the present application, the insertion body 21 is flexibly installed on the terminal fillet 23 via the flexible portion 22. In a specific structure, the flexible portion 22 is a fillet elastic piece having a flexible deformation structure. The fillet elastic piece is a right-angle bend, an acute-angle bend, a single-wave bend, or a multi-wave bend. The flexible deformation structure of the flexible portion 22 can use a plurality of forms, and the change in the flexible deformation structure of the flexible portion 22 does not affect the protection scope of this patent.

[0018] In order to further improve the connection stability between the connector 100 and the external insertion component 200, in the present application, the fixed base 1 is provided with a swing space 11 for accommodating the swing of the insulator 3. The insulator 3 is suspended in the swing space 11. There is a spacing space 4 between the insulator 3 and the fixed base 1 for the insulator 3 to swing back and forth. The spacing space 4 is for regulating the swing angle range of the insulator 3.

[0019] When inserted, there is a spacing space 4 between the insulator 3 and the fixed base 1 for the insulator 3 to swing back and forth. Due to this, the insertion body 21 swings back and forth within the swing space together with the insulator 3. That is, under the action of an external force, the insertion body 21 can realize translational and / or rocking mixed floating within the swing space 11. The female terminal contact elastic pieces on the insulator 3 and the insertion body 21 can adapt to the deviation caused by the non-coaxial and non-centering insertion between the connector 100 and the external insertion component 200 by translating and / or rocking. Thereby, it can overcome the horizontal offset and angular offset during insertion, effectively ensure the structural stability after the connector 100 and the external insertion component 200 are inserted, and avoid damage to the terminals and other components of the connector 100 and / or the external insertion component 200 due to insertion deviation during insertion. The structure is simple and easy to use.

[0020] The initial position is in a state where the center of the insulator 3 and the center of the fixed base 1 are the same. At this time, the center line A of the fixed base and the center line B of the insulator are both on the central plane extending along the front-rear direction. As shown in FIGS. 4A and 4B of the embodiment, when there is a deviation due to the non-coaxial and non-centering insertion between the connector 100 and the external insertion component 200, the insulator 3 undergoes a horizontal sliding △A to the left under the tensile force of the external insertion component 200, and at the same time, the end 32 of the insulator 3 generates a swing angle △B to the left. Thereby, the female terminal contact elastic pieces on the end 32 and the insertion body 21 can adapt to the deviation caused by the non-coaxial and non-centering insertion between the connector 100 and the external insertion component 200 by translating and rocking, and thereby can overcome the horizontal offset and angular offset during insertion.

[0021] In the present application, after the external insertion component 200 is pulled out from the connector 100, the external force received by the insulator 3 is released. Under the action of the elastic force for the flexible part 22 to recover from deformation, the insulator 3 floats and resets in the reverse direction, facilitating the next insertion and extraction connection.

[0022] The embodiments are shown in FIGS. 16 to 18. In the embodiments of the present application, at the bottom of the insulator 3, a spherical support point 31 or an arcuate surface support point 36 for supporting the angular runout and reset of the insulator 3 is provided. The spherical support point 31 is a spherical support point composed of two arcs installed intersectingly along the X direction and the Y direction. The arcuate surface support point 36 is an arcuate surface support point formed by a single arcuate portion installed along the X direction or the Y direction or a plurality of arcuate portions installed at intervals in parallel.

[0023] The function of the spherical support point 31 or the arcuate surface support point 36 is to withstand the downward pressing force on the insulator 3 when the external insertion part 200 is inserted, to avoid the insulator 3 moving downward and pulling the insulator to damage the pad between the terminal fillet 23 and the fixed base 1. At the same time, the contact between the spherical support point 31 or the arcuate surface support point 36 and the support surface is the contact between the spherical or arcuate surface and the plane. With such a structural design, in the runout process where the insulator 3 translates and / or swings in the runout space 11, it is realized that the insulator 3 rolls and / or slides on the support surface. That is, in this embodiment, the insulator 3 rolls and / or slides on the connection plate 6, so that due to the mutual pressing external force caused by the butting of the male joint and the female joint in the runout space 11, the butting angle between the insulator 3 and the insertion body 21 therein is automatically adjusted, and the structural stability after the connector 100 and the external insertion part 200 are inserted can be ensured.

[0024] In the embodiments of the present application, the upper end of the insulator 3 is an end portion 32 for insertion and extraction connection with the external insertion part 200. An insertion and extraction connection hole 321 is opened in the end portion 32. The insertion body 21 is fixedly installed in the insertion and extraction connection hole 321. The female terminal contact elastic piece at the upper end of the insertion body 21 is arranged in the insertion and extraction connection hole 321 and is close to the upper port of the insertion and extraction connection hole 321. On the lower side of the outer end of the terminal fillet 23, a terminal welding surface 231 is provided, and the terminal welding surface 231 is used for welding to the connection plate 6.

[0025] In the embodiments of the present application, arc surface guide structures 322 are respectively provided around the periphery of the end portion 32 to guide the external insertion component 200 to protrude outward when being inserted and removed and connected to the end portion 32. The plurality of arc surface guide structures 322 form a spherical crown surface structure that can be slidably fitted to the external insertion component. The arc surface guide structure 322 is a spherical crown protruding outward. Due to the arc surface guide structure 322, the external insertion component 200 can slide outward along the smooth spherical surface protruding outward and cover the end portion 32 easily, and at the same time, it is ensured that the end portion 32 can swing inside the external insertion component 200. Due to the arc surface guide structure 322, when guiding the external insertion component 200 to be inserted and removed and connected to the end portion 32, the end portion 32 can swing inside the external insertion component 200 by the spherical crown surface structure formed by the plurality of arc surface guide structures 322, so as to realize the adjustment of the insertion and removal angle of the end portion 32.

[0026] In addition to the above embodiments, the above function can be realized by using a ball-shaped end portion (not shown), and the structure is as follows. The end portion is provided with a large head whose outer periphery is spherical crown-shaped. When guiding the external insertion component to be inserted and removed and connected to the end portion by the large head, the end portion can swing inside the external insertion component by the spherical crown surface of the large head, so as to realize the adjustment of the insertion and removal angle of the end portion.

[0027] In the embodiments of the present application, the female terminal contact elastic piece in the insertion body 21 is a female terminal contact elastic piece having an offset tolerance function. In the specific structure of this embodiment, at the upper end of the insertion body 21, two elastic terminal elastic pieces 211 installed oppositely are provided. Between the two terminal elastic pieces 211, a receiving chamber 212 having two opposite side openings and used for inserting the terminal 203 of the external insertion component 200 is formed. The section between the two oppositely installed terminal elastic pieces 211 constitutes an offset tolerance section of the female terminal that can allow the offset of the insertion and removal connection of the terminal 203 of the external insertion component 200.

[0028] When inserting and removing and connecting, there are the following two connection states.

[0029] First, when the external insertion component 200 is inserted and connected to face the end portion 32, the terminal 203 of the external insertion component 200 is inserted into the accommodation chamber 212, and the two terminal elastic pieces 211 jointly clamp the terminal 203 of the external insertion component 200, thereby ensuring a stable electrical connection between the connector 100 and the external insertion component 200.

[0030] Second, when the external insertion component 200 is inserted and connected to the end portion 32 in an offset state, due to the offset tolerance range of the female terminal, the terminal 203 of the external insertion component 200 can protrude out of the accommodation chamber 212 through one of the two opposite openings to realize the insertion and connection, that is, the terminal 203 of the external insertion component 200 is arranged in the insertion and connection hole 321, and a part of the terminal 203 of the external insertion component 200 is exposed outside the accommodation chamber 212, but the other part still maintains an electrically connected state with the two terminal elastic pieces 211 in the accommodation chamber 212.

[0031] In addition to providing the two terminal elastic pieces 211, a plurality of pairs, for example, two pairs or three pairs of terminal elastic pieces 211 may be further set, and the change in the number of the terminal elastic pieces 211 does not limit the protection scope of the present application.

[0032] In the embodiment of the present application, the fixing portion 24 is a barb portion, and a locking groove 10 capable of locking and connecting to the barb portion is provided at the lower end of the fixed base 1. By being fixedly locked in the locking groove through the barb portion, the connection stability between the terminal fillet 23 and the fixed base 1 is enhanced, and damage to the terminal fillet 23 when the flexible portion 22 is flexibly deformed is avoided.

[0033] In the embodiment of the present application, the insertion and connection hole 321 is a square hole, and the insertion body 21 is provided with a locking portion capable of being locked in the insertion and connection hole. By the fitting of the locking portion and the square hole, the circumferential rotation of the conductive terminal with respect to the insertion and connection hole can be avoided, which is beneficial to enhancing the assembly stability between the conductive terminal 1 and the insulator 3.

[0034] The insertion and extraction connection hole 321 and the insertion body 21 may be further engaged and fitted with other irregular holes, and the change of the fitting structure between the insertion and extraction connection hole 321 and the insertion body 21 does not limit the protection scope of this application.

[0035] A further improvement is as follows. On one side of the outer wall of the engaging part, there is a protrusion 213 that can press the inner wall of the insertion and extraction connection hole 321 to reinforce the installation of the insertion body 21 in the insertion and extraction connection hole. The protrusion 213 can enhance the assembly stability of the insertion body 21 and avoid looseness during assembly.

[0036] A further improvement is as follows. There are a plurality of protrusions 213, and the plurality of protrusions 213 are installed at intervals along the vertical direction along the engaging part. The plurality of protrusions 213 further enhance the assembly stability of the insertion body 21.

[0048] As can be seen from the above, the position regulating structure can adopt a plurality of structural designs, and the change of the position regulating structure does not limit the protection scope of the present application. For example, the following can be adopted. Flanges are respectively provided on the front and rear sides and the left and right sides of the insulator 3, and the inner walls of the four circumferences of the swing space 11 are all stop walls. When the insulator 3 swings back and forth, the swing limit of the front and rear side flanges of the insulator 3 is stopped on the inner walls of the front and rear sides of the swing space 11, realizing the regulation of the swing angle range of the insulator 3 in the front and rear directions.

[0051] In the present application, a concave groove 152 is provided at the lower end of the insertion and extraction head of the external insertion component 151. The function of the concave groove 152 is to movably connect to the floating insulator. A second conductive terminal 121 is fixedly installed in the external insertion component 151, and the ends for the insertion and extraction connection of the plurality of second conductive terminals 121 are located in the concave groove 152.

[0052] In the present application, the connector 7 includes a fixed base 8, a first conductive terminal 9, and a floating insulator 10. The floating insulator is provided with a plurality of insertion holes 102, and the first conductive terminal 9 is fixedly engaged in the insertion holes 102. A plurality of second conductive terminals 121 correspond one-to-one to the plurality of first conductive terminals 9. When mating, the second conductive terminal 121 can be inserted into the insertion hole 102 and inserted and connected to the first conductive terminal 9.

[0053] In the present application, the first conductive terminal 9 is divided into an insertion body 91, a flexible part 95, and a conductive terminal fillet 96 in order from top to bottom. The floating insulator 10 is floatingly supported by the fixed base 8 via the insertion body 91, the flexible part 95, and the conductive terminal fillet 96.

[0054] The insertion body 91 is engaged in the insertion hole 102 by concave-convex fitting. The change in the fixed engagement structure by concave-convex fitting and the structure of the first conductive terminal 9 does not affect the protection scope of the present application.

[0055] In the present application, a plurality of fixed base holes 81 are installed along the outer periphery of the four sides of the fixed base 8. The plurality of conductive terminal fillets 96 are respectively engaged in the fixed base holes 81 after passing through the corresponding insertion holes 102, and the conductive terminal fillets 96 are welded to the substrate 161 after passing through the fixed base holes 81. The fixed base holes 81 are fitted to the conductive terminal fillets 96 so as to maintain the positions of the floating insulator 10, the first conductive terminal 9, and the fixed base 8.

[0056] In the present application, a bracket 131 is further installed between the fixed base 8 and the substrate 161. Convex portions 132 are provided on the left and right and both edges of the bracket 131. The bracket 131 is locked and connected to the locking groove 82 in the fixed base 8 via the convex portions 132. A bracket fillet 133 is provided at the lower end of the bracket 131. The bracket fillet 133 is welded to the substrate 161. The bracket is used to maintain the position of the fixed base on the substrate 161.

[0057] In the embodiment of the present application, a concave groove 83 is formed in the central part of the upper end of the fixed base 8. The block-shaped floating insulator 10 is arranged to float in the concave groove 83. A floating gap a for the movement of the floating insulator 10 is left between the four circumferences of the block-shaped floating insulator 10 and the inner wall of the concave groove 83. The floating gap a is used to regulate the left-right swing and floating of the floating insulator 10.

[0058] A further improvement of the concave groove 83 in Embodiment 4 is as follows. Notch 85 is provided on the groove walls of the two short sides at the front and rear of the concave groove 83 respectively. The notch 85 communicates with the locking groove 82 and the concave groove 83. Insulator lugs 111 are provided at both the front and rear ends of the block-shaped floating insulator 10 respectively. The insulator lugs 111 are arranged to float in the notch 85. The bracket 131 is provided with a flange 134 bent towards one side of the notch 85. The flange 134, together with the left side, right side and bottom side of the notch 85, constitutes a floating section for regulating the swing and floating of the insulator lug 111. Within the floating section, a sufficient floating interval b for the swing and floating of the insulator lug 111 is left between the four circumferences of the insulator lug 111 and the left side, right side, bottom side of the notch 85, and the flange 134. The floating interval b is used to regulate the up-down swing and floating of the floating insulator 10.

[0059] In order to perform pairing guidance for the end part for the insertion and connection of the second conductive terminal 121, a slope guide structure is provided between the second conductive terminal 121 and the insertion hole 102, which can be converted into an adjustment by pushing their mutual acting forces so that the floating insulator 10 floats during fitting. The slope guide structure includes a first sliding guide structure 103. The first sliding guide structure 103 is a part of a through hole with a large upper end opening and a small lower end opening of the insertion hole 102. A sliding guide slope 104 with a gradually decreasing inner diameter is provided between the upper end and the lower end of the through hole. In addition to using the sliding guide slope, a sliding guide arc surface can be used instead of the sliding guide slope to realize the sliding guide function. The change in the shape of the sliding guide surface does not affect the protection scope of the present application.

[0060] The second conductive terminal 121 is an insertion pin, and at the tip of the insertion pin, an inclined sliding guide surface 122 is provided to guide the insertion pin into the insertion hole.

[0061] For example, the second conductive terminal 121 is a cylindrical insertion pin, the tip of the cylindrical insertion pin presents an inverted cone, and through the sliding fit between the inclined sliding guide surface 122 on the outer periphery of the inverted cone and the sliding guide inclined surface 104 on the inner wall of the first sliding guide structure 103, the sliding guide action is realized during the pairing process. During the sliding process, after the first sliding guide structure 103 is pressed by the sliding guide inclined surface 104, it floats to one side. Thereby, when butting and fitting, it can be realized that the floating insulator 10 converts the mutual acting force into the adjustment by pushing it to float to one side. After adjusting with the floating insulator 10, the plurality of second conductive terminals 121 can be smoothly inserted into the corresponding insertion holes 102 in the axial direction.

[0062] In order to ensure the stability of the electrical connection of the pairing between the terminals, in the embodiments of the present application, the insertion body 91 is provided with a clamping portion 92 that can clamp the insertion portion of the second conductive terminal 121 during fitting to maintain the electrical connection. The structure of the clamping portion 92 is as follows. At the upper end of the insertion body 91, a plurality of elastic terminal elastic pieces 93 are provided. The central portion of the terminal elastic piece 93 is bent towards the center. Every two of the plurality of terminal elastic pieces 93 form a set. Each set of terminal elastic pieces 93 is installed oppositely along the circumferential direction. Between the plurality of terminal elastic pieces 93, a receiving chamber for inserting the second conductive terminal 121 is formed. The central portions of the plurality of terminal elastic pieces 93 are bent towards the center to form the clamping portion 92. With such a structural design, the receiving chamber has a receiving space with large upper and lower openings and a small inner diameter in the middle, thereby ensuring a stable electrical connection between the connector 7 and the external insertion component 151.

[0063] In a specific implementation, in addition to installing two terminal elastic pieces, a plurality of pairs, for example, two pairs or three pairs of terminal elastic pieces, may be installed. The change in the number of terminal elastic pieces does not limit the protection scope of the present application.

[0064] In order to facilitate the free rotation and rocking of the external inserted component 151 with respect to the floating insulator 10 during the pairing process, in the embodiment of the present application, the arc surface or inclined surface guide structure further includes a second sliding guide structure 103. In the second sliding guide structure 103, at the upper end of the floating insulator 10, a protrusion 112 is provided to guide the floating insulator 10 into the concave groove 152 at the lower end of the external inserted component 151. At the tips of the plurality of protrusions 112, a spherical crown structure that is slidable along the inner wall of the concave groove 152 and can rotate and rock within the concave groove 152 to fit is formed. During pairing, first, the external inserted component presses against the arc-shaped sliding guide surface outside the protrusion 112 at the head part of the floating insulator 10 by the spherical crown structure, and the floating insulator 10 swings by an angle under the acting force of the external inserted component 151, thereby guiding the plurality of second conductive terminals 121 to be smoothly inserted into the insertion holes. The floating insulator 10 can easily adjust the angular position with respect to the external inserted component 151 during insertion and extraction connection, and the floating insulator 10 can avoid sticking to the concave groove 152 of the external inserted component 151 during pairing.

[0065] In the embodiment of the present application, at the bottom of the floating insulator 10, there is a spherical support point 141 that supports its angular swing and reset. The spherical support point 141 is used to provide support in the height direction. The spherical support point 141 protects the first conductive terminal 9 and is used to avoid damage to the pad at the first conductive terminal 9 when the floating insulator 10 is pressed downward during pairing. Also, the spherical support point 141 can support the angular swing and reset of the floating insulator 10, and the spherical support point 141 may be installed on the fixed base 8 or the floating insulator 10.

[0066] The spherical support point 141 is located at the center position of the bottom of the concave groove 83 of the fixed base 8, and the spherical support point 141 and the fixed base 8 are an integrally formed structure by injection molding.

[0067] The spherical support point 141 is located at the center position of the bottom of the floating insulator 10, and the spherical support point 141 and the floating insulator 10 are an integrally formed structure by injection molding.

[0068] In addition to the structure of the bracket 131 in Embodiment 4 and Embodiment 5, the present application can also restrict the movement of the floating insulator 10 by further improving the structure of the concave groove 83. For example, as shown in Embodiment 6 of the present application, at the bottom of the front and rear ends of the floating insulator 10, there are lower position restricting strips 101 protruding outward along the two short side directions respectively. At the top of the front and rear end groove walls of the concave groove 83 in the fixed base 8, there are upper position restricting strips 84 protruding from the groove walls along the two short side directions respectively. The upper position restricting strip 84 and the lower position restricting strip 101 are installed at an interval up and down. During the process of the floating insulator 10 rotating and oscillating along the front - rear direction, the upper position restricting strip 84 can restrict the upper rotation and oscillation limit position of the lower position restricting strip 101, and the lower rotation and oscillation limit position of the lower position restricting strip 101 is restricted by the front and rear end groove walls of the concave groove 83. Such a structural design does not require connecting the concave groove 83 with the locking groove 82 where the bracket 131 is located, nor does it require cutting and bending the bracket 131 to form a stop plate compared with Embodiment 4 and Embodiment 5. The structural design of Embodiment 5 has a simpler structure of the bracket 131, but the disadvantage is that the structures of the concave groove 83 and the floating insulator 10 become more complex.

[0069] In addition to the improved structure of the concave groove 83 in Embodiment 4 and Embodiment 6, the concave groove 83 may further have another implementation structure. For example, a further improvement of Embodiment 5 based on Embodiment 4 is as follows. Based on the structure of the concave groove 83 designed in Embodiment 4, the concave groove 83 can be further simplified. For example, for the concave groove 83, only the groove walls installed along the short sides of its front and rear ends are left. At this time, the left - right rotation and oscillation of the floating insulator 10 are not restricted by the concave groove 83, and the floating insulator 10 has a butting performance that allows a larger deviation in the left - right direction.

[0070] The operating principles of Example 4, Example 5, and Example 6 of this application are as follows. In an eccentric state that is not coaxial, when the external inserted component 151 presses against the protrusion 112 of the head portion of the floating insulator 10, the floating insulator 10 deflects by an angle under the acting force of the external inserted component 151. Through the mutual fitting of the sliding guide inclined surface 104 in the insertion hole 102 and the inclined sliding guide surface 122 at the tip of the insertion pin, the second conductive terminal 121 is guided to be axially inserted into the insertion hole 102, and a plurality of second conductive terminals 121 can be smoothly inserted into the insertion hole 102. When the second conductive terminal 121 is inserted and connected to the first conductive terminal 9 in the insertion hole 102, the clamping portion 92 between each second conductive terminal 121 and the first conductive terminal 9 maintains a pressed and adhered state, thereby ensuring a stable electrical connection between the connector 7 and the external inserted component 151.
