Description

Technical Field

[0001] The utility model relates to the technical field of terminals, in particular to an electric connection seat with a grounding function. Background Art

[0002] With the continuous development of electronic products, the connections between various electronic products and their peripheral devices are becoming more and more frequent. It is a common way to connect electronic products and their peripheral devices through electrical connectors, so the frequency of use of electrical connectors has also increased. Electrical connectors are so widely used in the electronic field that manufacturers have gradually changed from small-scale production to large-scale batch production to meet market demand. However, after plugging and unplugging, the crimping terminals of existing electrical connectors are prone to loosening, affecting the stability of the connection; in addition, the conductive part of the front end of the crimping terminal in the current connector generally has an electrical gap of 1.5-2mm with the socket. The electrical gap is small and it is easy to contact and conduct electricity with the test finger, which cannot play the role of anti-touch finger effect.

The utility model has a novel structure and ingenious design. When two cable connectors are plugged into each other, the plug block of one cable connector is plugged into the receiving cavity of the other cable connector, and the conductive terminals in the two receiving cavities contact each other; the cable connectors can be male and female to each other, and have strong versatility; in addition, through the cooperation of the plug block and the slot, a row of two or more cable connectors can be spliced ​​together, which is easy to use and convenient for splicing and assembling multiple cable connectors.

[0004] When a connector is connected to another connector, the connection is achieved by multiple terminals contacting each other, and in the above scheme, the structure of each terminal is the same. The metal connecting piece of the connector will have a certain amount of static electricity. When in direct contact, the static electricity generated may damage the connector and cause a momentary short circuit. Utility Model Content

[0010] Furthermore: a partition is arranged between the bottom conductive groove and the conductive cavity, and the partition is formed with a through groove for the conductive strip to pass through so that the bottom conductive groove of the limiting plate is connected with the conductive cavity.

[0011] Furthermore: a raised conductive contact surface is formed at the outer end of the conductive strip.

[0012] Furthermore: an elastic strip is arranged between the bottom conductive groove and the conductive cavity, one end of the elastic strip is fixed to the conductive cavity, and the other end of the elastic strip is pressed against the bottom of the conductive contact surface to elastically drive the conductive contact surface to elastically tilt up.

[0013] Furthermore: a stop groove is formed at the outer end of the conductive strip and is located at the bottom of the conductive contact surface, and one end of the elastic strip close to the conductive contact surface abuts against the stop groove.

[0014] Furthermore: a top conductive slot arranged opposite to the bottom conductive slot is formed at the bottom of the insertion end, the width of the top conductive slot is greater than the width of the bottom conductive slot, and a portion of the conductive contact surface of the metal conductive sheet is tilted toward the top conductive slot.

[0017] The beneficial effects of the utility model are as follows: the groove structure formed between the insertion end and the limiting plate can allow another connecting terminal to be inserted, and contact with the metal conductive sheet of the bottom conductive groove to achieve conductive connection; because the length of the metal conductive sheet of the grounding terminal is greater than the length of the metal conductive sheet of the conductive terminal; therefore, when inserted, it will be in conductive contact with the metal conductive sheet of the grounding terminal, and because the metal conductive sheet is grounded, the static electricity of the connecting terminal and the connecting seat will be eliminated in time, thereby reducing the failure rate.

[0029] The utility model is described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-4As shown, an electrical connection seat with a grounding function includes a connection seat 1, a plurality of connection terminals 11 are arranged in the connection seat 1, and the plurality of connection terminals 11 are spliced ​​with each other. The connection terminal 11 includes an insulator 14 and an insertion end 15 and a limiting plate 16 formed at intervals on the insulator 14, a groove structure 17 is formed between the insertion end 15 and the limiting plate 16, and the limiting plate 16 is formed with a bottom conductive groove 19, and the bottom conductive groove 19 is installed with a metal conductive sheet 2, and one end of the metal conductive sheet 2 is fixed to the insulator 14; one of the connection terminals 11 is divided into a grounding terminal 12 and a conductive terminal 13, wherein the length of the metal conductive sheet 2 of the grounding terminal 12 is greater than the length of the metal conductive sheet 2 of the conductive terminal 13, and the metal conductive sheet 2 of the grounding terminal 12 extends outward.

[0031] The groove structure 17 formed between the insertion end 15 and the limiting plate 16 can allow the insertion end 15 of another connecting terminal 11 to be inserted, and contact the metal conductive sheet 2 of the bottom conductive groove to achieve conductive connection; since the length of the metal conductive sheet 2 of the grounding terminal 12 is greater than the length of the metal conductive sheet 2 of the conductive terminal 13; therefore, when inserted, it will be in conductive contact with the metal conductive sheet 2 of the grounding terminal 12. Since the metal conductive sheet 2 is grounded, the static electricity of the connecting terminal 11 and the connecting seat 1 will be eliminated in time, thereby reducing the failure rate.

[0032] Specifically, the metal conductive sheet 2 includes a conductive cylinder 21, a stopper 22 and a conductive strip 23, wherein the stopper 22 is located between the conductive cylinder 21 and the conductive strip 23, wherein the conductive cylinder 21 and the stopper 22 are both located in the insulator 14, the insulator 14 is formed with a conductive cavity 24 for installing the conductive cylinder 21 and the stopper 22, and the tail of the insulator 14 is formed with a conductive port 25 connected with the conductive cavity 24. The conductive cylinder 21 of the metal conductive sheet 2 is installed in the conductive cavity 24 of the insulator 14, and the stopper 22 cooperates with the side wall of the conductive cavity 24 to prevent the metal conductive sheet 2 from shifting from the bottom conductive groove 19 or from the conductive cavity 24, thereby ensuring the stability of the conductive connection, and the connecting terminal 11 can be conductively connected to the terminal through the conductive port 25 formed at the tail of the insulator 14, and the groove structure 17 formed between the insertion end 15 and the limiting plate 16 formed on the front of the insulator 14 can be inserted into the connecting terminal 11 for conductive connection, thereby realizing the connection function.

[0033] Preferably, a partition 26 is provided between the bottom conductive groove 19 and the conductive cavity 24. The partition 26 is formed with a through groove 27 for the conductive bar 23 to pass through so that the bottom conductive groove 19 of the limiting plate 16 is connected with the conductive cavity 24. The width of the through groove 27 is small. After the conductive bar 23 passes through, the conductive bar 23 can be prevented from shaking, and the conductive bar 23 can be positioned to prevent the conductive bar 23 from shifting.

[0034] A raised conductive contact surface 28 is formed at the outer end of the conductive strip 23. When the insertion end 15 of another connecting terminal 11 is inserted into the groove structure 17 between the insertion end 15 and the limiting plate 16, the raised conductive contact surface 28 can contact the metal conductive sheet 2 of the other connecting terminal 11 more stably, thereby ensuring the conductive stability.

Under the elastic drive of the elastic strip 29, the conductive contact surface 28 can tilt up, and when the insertion end 15 of another connecting terminal 11 is inserted, the conductive contact surface 28 will be pressed down to the bottom conductive groove 19 after contacting the connecting terminal 11, and under the elastic drive of the elastic strip 29, the metal conductive sheet 2 of the connecting terminal 11 in this case will be in close contact with the conductive area of ​​the other connecting terminal 11 to ensure the stability of conduction.

[0036] Preferably, a stop groove 30 is formed at the outer end of the conductive strip 23 and is located at the bottom of the conductive contact surface 28. One end of the elastic strip 29 close to the conductive contact surface 28 abuts against the stop groove 30. The stop groove 30 contacts the outer end of the elastic strip 29, so that one end of the elastic strip 29 is always connected to the conductive strip 23 to maintain an elastic connection.

[0037] A top conductive groove 18 is formed at the bottom of the insertion end 15 and is arranged opposite to the bottom conductive groove 19. The width of the top conductive groove 18 is greater than that of the bottom conductive groove 19. A portion of the conductive contact surface 28 of the metal conductive sheet 2 is tilted toward the top conductive groove 18. The groove structure 17 formed by the top conductive groove 18 and the bottom conductive groove 19 can surround another inserted connection terminal 11 to prevent the connection terminal 11 from shifting and falling off after insertion.

[0038] Preferably, the cross section of the insulator 14 is in the shape of a U-shaped triangle.

[0039] Preferably, two adjacent side walls of the insulator 14 are formed with raised raised connecting blocks 191, and two adjacent side walls of the insulator 14 are formed with concave guide connecting grooves 192. Two adjacent connecting terminals 11 are spliced ​​with each other through the raised connecting blocks 191 and the guide connecting grooves 192. The raised connecting blocks 191 and the guide connecting grooves 192 are both formed along the length direction of the insulator 14. According to needs, multiple connecting terminals 11 can be installed on a connecting seat 1 for connection. The spliced ​​connecting terminals 11 have good stability and can only be separated from the length direction of the connecting terminals 11 for disassembly.

[0040] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.
