Description

Technical Field

[0001] This utility model relates to a stable connector. Background Technology

[0002] Chinese patent CN202322613537.2 discloses a miniature radio frequency switch with good resilience, including a housing, an insulating body fixed in the housing, and conductive terminals fixed in the insulating body. The insulating body includes a first insulating body and a second insulating body that are fitted together in the vertical direction. The conductive terminals include a stationary terminal sandwiched between the first insulating body and the second insulating body and a movable terminal that is in elastic contact with the stationary terminal. The first insulating body is provided with a socket for receiving external connector pins. The movable terminal is located directly below the socket. Supporting leaf springs are provided on both sides of the movable terminal, and the supporting leaf springs abut against the second insulating body.

[0003] The moving terminal includes a flexible arm positioned in the middle, with the socket located directly above the flexible arm. An "I"-shaped switch contact protrusion is located at one end of the flexible arm. One end of the stationary terminal has a switch contact area positioned directly above the switch contact protrusion, and the two are in elastic contact. Under normal conditions, the switch contact protrusion and the switch contact area are in contact, and the RF switch is in the ON state. When a pin is inserted, as the pin moves downwards from the socket, it presses down on the flexible arm, causing the switch contact protrusion to swing downwards and separate from the switch contact area, thus disengaging the RF switch. When the external force is removed, the flexible arm returns to its original shape, causing the switch contact protrusion to swing upwards and make contact with the switch contact area, restoring the RF switch to the ON state.

[0004] The second insulating body has a movable slot, in which both the moving terminal and the stationary terminal are located. The moving terminal can swing up and down within the movable slot, and the socket is located above the movable slot. The moving terminal swings up and down within the movable slot to achieve elastic contact and separation with the stationary terminal, thereby realizing the on and off states of the RF switch.

[0005] Both the moving and stationary terminals are provided with several limiting holes, and the bottom of the first insulating body is also provided with limiting protrusions that match the limiting holes. The moving and stationary terminals are engaged into the limiting protrusions through the limiting holes. The limiting protrusions on the first insulating body limit the moving and stationary terminals, preventing their positions from shifting.

[0006] The moving terminal of the aforementioned miniature RF switch is engaged with the limiting protrusion through a limiting hole to achieve positioning and prevent displacement of the moving terminal. However, since the moving terminal only has one limiting hole, the positioning effect is limited. Therefore, improvements are needed. Utility Model Content

[0007] The purpose of this invention is to provide a stable connector to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the technical solution used in this utility model is as follows: A stable connector includes a housing, an insulating body fixed within the housing, and conductive terminals fixed within the insulating body. The insulating body includes a first insulator and a second insulator that fit together vertically. The conductive terminals include a stationary terminal sandwiched between the first and second insulators and a movable terminal that elastically contacts the stationary terminal. The first insulator has a socket for receiving external connector pins. The movable terminal includes an elastic arm, support springs on both sides of the elastic arm, switch contact protrusions at two opposite ends of the elastic arm, and a positioning portion. The socket is located directly above the elastic arm. The positioning portion has a positioning hole. The bottom of the first insulator has a positioning protrusion that matches the positioning hole. Both sides of the positioning portion are connected to extension portions. The characteristic feature is that the ends of the two extension portions bend towards the support springs and form slots with the positioning portions. The bottom of the first insulator has positioning blocks that match each slot.

[0009] Furthermore, one side of the two supporting leaf springs is two extensions, and the other opposite side is a stationary terminal. The stationary terminal includes a switch contact portion, which is located directly above the switch contact protrusion, and the two elastically abut against each other. The end of the switch contact portion away from the moving terminal is connected to a positioning portion, which has a positioning hole. Extensions are connected to both sides of the positioning portion, and the ends of the two extensions bend towards the supporting leaf springs to form slots with the positioning portion and the switch contact portion. The bottom of the first insulator is provided with positioning blocks that are adapted to each slot, and the bottom of the first insulator is also provided with positioning protrusions that are adapted to the positioning holes.

[0010] Furthermore, at the connection point between the switch contact part and the second positioning part, two downward inclined arms are formed by stamping and bending, which disconnects the second positioning part. The two downward inclined arms are connected by a horizontal connecting part, which is connected to the second positioning part. The switch contact protrusion elastically abuts against the horizontal connecting part and the two downward inclined arms simultaneously.

[0011] Furthermore, the opposite sides of the positioning part one and the positioning part two are bent and extended to form welding feet, and the two opposite sides of the second insulator are provided with clearance notches for the two welding feet to extend out of the second insulator.

[0012] Furthermore, the outer shell is provided with fastening parts on the other two opposite sides of the second insulator, which fasten to the bottom of the second insulator. Each of the fastening parts on both sides has a locking hole, and the other two opposite sides of the second insulator protrude outward to form protrusions that cooperate with the locking holes.

[0013] Furthermore, the supporting leaf springs on both sides of the elastic lever arm are symmetrically arranged on both sides of the elastic lever arm, and one end of the supporting leaf spring is perpendicularly connected to the elastic lever arm.

[0014] Furthermore, the second insulator is provided with a receiving cavity, and both the moving terminal and the stationary terminal are disposed in the receiving cavity. The moving terminal can swing up and down in the receiving cavity, and the socket is disposed above the receiving cavity.

[0015] Furthermore, the supporting leaf springs on both sides of the elastic lever arm are symmetrically arranged relative to the central axis of the insertion hole.

[0016] Furthermore, the first insulator is provided with symmetrical fasteners on both sides of the socket, and the housing is provided with positioning grooves that cooperate with the corresponding fasteners.

[0017] Furthermore, both the first and second insulators are made of insulating plastic material, and the outer shell is a metal shell.

[0018] Compared with the prior art, the main advantages of this utility model are reflected in: (1) By bending the two extensions of the moving terminal of the conductive terminal and forming a slot with the positioning part of the moving terminal and opening a positioning hole on the positioning part, and providing a positioning block that matches each slot and a positioning protrusion that matches the positioning hole at the bottom of the first insulator, three points are fixed on the moving terminal, making the moving terminal of the conductive terminal more stable to install.

[0021] (4) On the basis of the fastening part, the outer shell is further fitted with a snap hole to fasten with the protrusion on the second insulating body, so that the second insulating body and the outer shell are more firmly fixed. Attached Figure Description

[0024] To facilitate a better understanding of the purpose, structure, features, and effects of this utility model, the present utility model will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figure 1-13As shown, the stable connector includes a housing 1 (made of metal), an insulating body fixed inside the housing 1, and conductive terminals fixed inside the insulating body.

[0026] The housing 1 includes a generally square plate 11. A cylindrical sleeve 12 protrudes upward from the center of the top surface of the plate 11. Two opposite sides of the plate 11 are connected to downward-extending L-shaped fastening parts 13. Each of the two fastening parts 13 has a locking hole 131 and is also a welded part. Two positioning grooves 14 are provided on the inner side of the cylindrical sleeve 12, and the two positioning grooves 14 are symmetrically arranged along the axis of the cylindrical sleeve 12.

[0027] The insulating body includes a first insulator 2 and a second insulator 3 that fit together vertically. The first insulator 2 includes a base 21, with a plate 11 located on the upper surface of the base 21. The upper side of the base 21 protrudes upward to form a mating portion 22 (cylindrical structure), and a cylindrical sleeve 12 is fitted over the mating portion 22. The mating portion 22 is provided with a socket 221 for receiving external connector pins. The socket 221 is located in the middle of the top surface of the mating portion 22 and extends downward through the bottom surface of the mating portion 22 and the base 21. Two fastening blocks 23 are provided on the upper side of the base 21. The two fastening blocks 23 are symmetrically arranged on both sides of the mating portion 22 and are fixed in corresponding positioning grooves 14. The base 21 is a square base with four sides protruding outward to form mating blocks 211.

[0028] The bottom surface of the base 21 has a positioning protrusion 1 212 and a positioning protrusion 213. The positioning protrusion 1 212 and the positioning protrusion 213 are located on both sides of the insertion hole 221. The distance between the positioning protrusion 1 212 and the edge of the insertion hole 221 is less than the distance between the positioning protrusion 213 and the edge of the insertion hole 221. The bottom surface of the base 21 has a positioning block 1 214 on each side of the positioning protrusion 1 212 and a positioning block 215 on each side of the positioning protrusion 213.

[0029] The second insulator 3 has a square structure with a recessed top surface forming a receiving cavity. Both the conductive terminal and the first insulator 2 are housed within this cavity, and a socket 221 is positioned above it. Two opposite sides of the second insulator 3 have clearance notches 31 at their midpoints. The other two opposite sides of the second insulator 3 have recesses 32 formed inwards towards the inner wall of the receiving cavity. These recesses 32 engage with mating blocks 211 on two opposite sides of the base 21, and the mating blocks 211 on the other two opposite sides of the base 21 engage with the clearance notches 31. The outer walls of the other two opposite sides of the second insulator 3 with the recesses 32 protrude outwards to form protrusions 33. Two fastening parts 13 fasten to the bottom of the second insulator 3, and the two protrusions 33 correspondingly engage with two locking holes 131.

[0030] The conductive terminals include a stationary terminal 4 sandwiched between a first insulator 2 and a second insulator 3, and a movable terminal 5 in elastic contact with the stationary terminal 4. Both the movable terminal 5 and the stationary terminal 4 are disposed within the receiving cavity. The movable terminal 5 is located directly below the socket 221 and can swing up and down within the receiving cavity to achieve elastic contact and separation with the stationary terminal 4, thereby enabling the connector to conduct and disconnect. The socket 221 is used to connect external connector pins. The movable terminal 5 swings up and down by moving the external connector pins, thereby enabling the connector to conduct and disconnect.

[0031] The moving terminal 5 includes an elastic arm 51, support leaf springs 52 disposed on both sides of the elastic arm 51, switch contact protrusions 53 disposed at two opposite ends of the elastic arm 51, and a positioning part 54. The positioning part 54 is bent and extended on the side away from the elastic arm 51 to form a welding foot 55, which protrudes from one of the clearance notches 31. The socket 221 is located directly above the elastic arm 51. The support leaf springs 52 abut against the second insulator 3. The two support leaf springs 52 are symmetrically disposed on both sides of the axis of the socket 221. When the connector pin is inserted into the socket 221, the support leaf springs 52 and the moving terminal 5 are subjected to uniform force on the left and right sides. When the external connector pin is removed, the rebound degree of the left and right sides of the moving terminal 5 is consistent, which can effectively and quickly cause the switch contact protrusions 53 to rebound, thus improving the device life. Supporting leaf springs 52 are symmetrically arranged on both sides of the elastic lever arm 51, and one end of the supporting leaf spring 52 is perpendicularly connected to the elastic lever arm 51, which can maximize the supporting force of the supporting leaf spring 52 and improve the rebound speed of the elastic lever arm 51. The two supporting leaf springs 52 are inclined downward and abut against the bottom wall of the recess 32. By setting the supporting leaf springs 52 downward, good elastic support force can be provided, so that the switch contact protrusion 53 has a good rebound effect.

[0032] The switch contact protrusion 53 is in the shape of a straight line. This straight-line structure increases the contact area with the stationary terminal 4, preventing poor contact caused by external dust, dirt, or other contaminants, and ensuring a stable signal connection. The switch contact protrusion 53 is located below the stationary terminal 4. A positioning hole 541 is formed on the positioning part 54, and the positioning protrusion 212 is adapted to the positioning hole 541. Extensions 56 are connected to both sides of the positioning part 54. The ends of both extensions 56 bend towards the supporting leaf spring 52 and form slots 57 with the positioning part 54. Each slot 57 is adapted to a corresponding positioning block 214. The positioning protrusion 212 and positioning block 214 of the first insulator 2 respectively position the positioning hole 541 and slot 57 of the moving terminal 5, preventing the moving terminal 5 from shifting position and improving its stability.

[0033] The stationary terminal 4 includes a switch contact portion 41, which is located directly above the switch contact protrusion 53, and the two are in elastic contact. Under normal conditions, the switch contact protrusion 53 and the switch contact portion 41 are in contact, and the connector is in a conductive state. When a connector pin is inserted, as the pin moves downward from the socket 221, it presses down on the elastic arm 51, causing the switch contact protrusion 53 to swing downward and separate from the switch contact portion 41, thus disconnecting the connector. When the external force is removed, the elastic arm 51 returns to its original shape, causing the switch contact protrusion 53 to swing upward and contact the switch contact portion 41, restoring the connector to a conductive state.

[0034] The end of the switch contact 41 furthest from the moving terminal 5 is connected to a positioning part 42. The positioning part 42 has a positioning hole 421, which is fitted with a positioning protrusion 213. Extensions 422 are connected to both sides of the positioning part 42. The ends of both extensions 422 bend towards the support spring 52 and form slots 423 with the positioning part 42 and the switch contact 41. These slots 423 fit with corresponding positioning blocks 215. The positioning protrusions 213 and positioning blocks 215 of the first insulator 2 respectively position the positioning hole 421 and slot 423 of the stationary terminal 4, preventing displacement of the stationary terminal 4 and improving its stability.

[0035] At the connection point between the switch contact portion 41 and the second positioning portion 42, two downward inclined arms 411 are formed by stamping and bending, disconnecting them from the second positioning portion 42. The two downward inclined arms 411 are connected by a horizontal connecting portion 412, which is connected to the second positioning portion 42. The two downward inclined arms 411 and the horizontal connecting portion 412 together constitute the switch contact portion 41. The switch contact protrusion 53 elastically abuts against the horizontal connecting portion 412 and the two downward inclined arms 411 simultaneously. The two downward inclined arms 411 can provide elastic abutting contact force when in contact with the switch contact protrusion 53. The side of the second positioning portion 42 away from the switch contact portion 41 is bent and extended to form a second welding foot 43, which extends from another clearance notch 31.

[0036] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
