Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular relates to a connector. Background Art

[0002] Connectors are now used in a wider range of environments, and in daily use, they need to be rotated and twisted to improve contact or process. In addition, many components have become more and more sophisticated, and if you want to install connectors inside, you need to achieve a more mini effect, which is a great challenge to the manufacturing process or transmission performance.

[0003] At present, in the market, after the existing signal connectors are plugged in and mated, the male and female ends are relatively static, and the contact position is also relatively static. When there is relative movement in the local position of the frame, conventional connectors cannot meet the functional requirements. The existing connectors on the market generally use fixed connection and fixed contact, that is, they are plugged in a certain fixed direction, and there is a locking structure in a fixed position after plugging in. After locking, the connector cannot move to ensure stable docking between the terminals. Because it is generally believed that the stability of the connector during plugging can maximize the service life and ensure the reliability of the connection.

[0004] Defects of the prior art: 1. After the existing conventional signal connectors are plugged in, the male and female ends are relatively fixed. In a vibration environment, the terminal contact part is a rigid connection, which has the risk of contact failure; 2. When relative movement is required at a local position of the vehicle body, the conventional connector can only achieve connection in a static state, and cannot maintain connection while in relative movement; 3. In extremely narrow areas, due to the small gap, the normal signal connector cannot pass through the gap to achieve connection.

[0005] In view of this, it is necessary to develop a connector to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below through specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] refer to Figures 1 to 3 and Figure 5 A connector comprises a male end 1, a female end 2, a guide plate 3, a terminal 5, and an elastic seal 4. The male end 1 is coaxially arranged with the female end 2 and rotatably connected. The male end 1 has a plurality of fixed grooves 111 in a circumferential array, and the female end 2 has a plurality of guide grooves 221 in a circumferential array corresponding to the fixed grooves 111. The guide grooves 221 are connected with the fixed grooves 111. An elastic seal 4 is arranged on the top of the female end 2, and a guide plate 3 is fixedly connected to the bottom of the female end 2. A plurality of terminals 5 are vertically arranged in the fixed groove 111, and rods of a plurality of terminals 5 pass through the guide groove 221 and slide and are electrically connected with the guide plate 3. The lengths of the lines connecting the end points of the guide groove 221 and the geometric center point of the female end 2 are equal or unequal, and the terminals 5 can be partially offset in the guide groove 221.

[0034] refer to Figure 3 and Figure 5The male end 1 is configured as a hollow disc-shaped structure, a male end mounting groove 11 is provided on the top of the male end 1, and a fixing groove 111 is provided at the bottom of the male end mounting groove 11. The fixing groove 111 is arranged at the bottom of the male end mounting groove 11, which can play a certain protective role for the terminal 5 in the fixing groove 111. Specifically, the fixing groove 111 includes a first fixing groove 1111 and a second fixing groove 1112. The first fixing groove 1111 is arranged at the bottom of the male end mounting groove 11, and the second fixing groove 1112 is connected to the bottom of the first fixing groove 1111. The first fixing groove 1111 and the second fixing groove 1112 are coaxially arranged to ensure the smoothness of the assembly connection. Furthermore, the outer dimensions of the first fixing groove 1111 are larger than the outer dimensions of the second fixing groove 1112. The above design can form a fixed step between the first fixing groove 1111 and the second fixing groove 1112, which is convenient for the protruding surface of the terminal 5 to abut against the fixing step to form a state in which the terminal 5 is fixed in multiple places. A male terminal connection block 12 is disposed at the bottom of the male terminal 1 , and the fixing groove 111 passes through the male terminal connection block 12 , so as to facilitate the connection of the terminal 5 to the guide groove 221 .

[0035] refer to Fig. 9 The terminal 5 is specifically an elastic terminal 5. The terminal 5 is provided with a solder cup 51, a protrusion 52, a fixing portion 53, and a conductive body 54 in sequence. The end surface of the protrusion 52 away from the solder cup 51 abuts against the bottom surface of the male end mounting groove 11. The fixing portion 53 is inserted into the first fixing groove 1111, and the conductive body 54 is inserted into the second fixing groove 1112. The first fixing groove 1111 and the second fixing groove 1112 are set to a runway type to improve the fault tolerance of the terminal 5 assembly. The terminal 5 is fixed by limiting the two parts in the first fixing groove 1111 and the second fixing groove 1112 to achieve the reliability of the connection. After the cable is welded at the solder cup 51, the male end mounting groove 11 is filled with glue to fix the terminal 5. When assembling and connecting, the end of the conductive body 54 can float relative to the connection surface in a direction vertical to the conductive plate 3 to prevent the conductive body 54 from having a rigid impact with the conductive plate 3.

[0036] refer to Figure 1 , Figure 5 and Figure 6The female end 2 is configured as a hollow disc-shaped structure. Two sealing grooves 21 are coaxially arranged on the top of the female end 2. An elastic sealing member 4 is arranged in the sealing groove 21. Specifically, the elastic sealing member 4 is an O-ring or a Y-ring or other forms of sealing members. It is worth noting that the setting of the sealing elastic member can not only play a good sealing role after the male end 1 and the female end 2 are rotated and connected, but also when the overall connector is subjected to external force, the male end 1 and the female end 2 can achieve a certain range of displacement or a certain angle of deflection, thereby reducing or eliminating the adverse effects of the external force on the stable connection of the connector. A female end connection groove 22 is arranged between the two sealing grooves 21 to cooperate with the male end 1 docking block. Preferably, the male end 1 docking block and the female end connection groove 22 are matched with a small gap to avoid a large radial offset after the male end 1 and the female end 2 are connected, thereby preventing damage to the terminal 5 and improving the service life.

[0037] It is to be noted that the guide slide groove 221 is arranged at the bottom of the female end connection groove 23, and the female end mounting groove 23 is arranged at the bottom of the female end 2. The guide slide groove 221 is connected to the female end mounting groove 23, so that the end of the conductive body 54 of the terminal 5 is connected to the conductive plate 3. Furthermore, the guide slide groove 221 is arranged in an arc shape, and the radius of the guide slide groove 221 is greater than or equal to the radius of the conductive body 54, so that the conductive body 54 can slide smoothly in the guide slide groove 221. In addition, it is worth noting that the lengths of the lines connecting the two end points of the guide groove 221 and the geometric center point of the female end 2 are equal or unequal. Preferably, the lengths of the lines connecting the two end points of the guide groove 221 and the geometric center point of the female end 2 are unequal. The above-mentioned design method can make the trajectory of the conductive body 54 in the guide groove 221 not be a curve coaxial with the sealing groove 21. Through this design, the activity of the conductive body 54 in the present application is compared with that of ordinary connectors. It can not only rotate circumferentially in space, but also deviate within a certain range in the plane space. When subjected to external force, the range and type of activity of the conductive body 54 are The increase further improves the application range of the overall connector, ensuring that the connector can achieve reliable connection under specific rotation and a certain range of offset. In addition, since the trajectory of the conductive body 54 in the guide groove 221 is not a curve coaxial with the sealing groove 21, the conductive body 54 will generate a small range of concentrated stress in the guide groove 221. However, since the female end 2 is made of insulating material and has a certain elastic force, when the conductive body 54 moves in the guide groove 221, the guide groove 221 will generate a certain amount of elastic force to eliminate the concentrated stress. Even if there is any residual concentrated stress, it will not affect the overall connection and can be ignored.

[0038] refer to Figure 7 and Figure 8The female end mounting groove 23 is fixedly connected with a guide plate 3. The guide plate 3 in the present design is a copper bar, and the guide plate 3 is set to be a hollow disc. Specifically, there are several guide blocks 31 in a circular array corresponding to the guide groove 221 on the top of the guide plate 3. The guide blocks 31 are made of conductive material. In addition, they have good strength and wear resistance, which improves their service life. After the end of the conductor 54 passes through the guide groove 221, it slides with the guide block 31 and is electrically connected. Each electrical signal is transmitted from the conductor 54 to the guide plate 3. There are several connecting pieces 32 in a circular array at the bottom of the guide plate 3. Cables are welded on the connecting pieces 32 (the guide plate 3 is placed in the female end mounting groove 23 after the cables are welded on the connecting pieces 32 and fixed with glue). The cables are connected to the rear-end components. After the electrical signals are transmitted to the guide plate 3, they are conducted to the rear-end components through the connecting pieces 32.

[0039] In summary, the male end 1, the female end 2 and the guide plate 3 are all hollow disc-shaped designs. After the units are connected to each other, the interior of the overall connector is hollow and can be used to place the tube body and other parts. After the male end 1 and the female end 2 are matched with each other, the terminal 5 contacts the guide plate 3 to achieve electrical connection; when the female end 2 or the male end 1 of the connector is fixed, the male end 1 or the female end 2 rotates a certain angle about its own axis to ensure that it can rotate a certain angle in the projection plane, and the end of the conductor 54 of the terminal 5 always keeps in contact with the copper busbar, ensuring the continuity of the electrical connection. At the same time, the setting of the elastic seal 4 allows the male end 1 and the female end 2 to deflect at a certain angle in the spatial plane.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
