Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a connector with high connection strength. Background Art

[0002] A connector is an electrical component used to connect two or more circuit devices. Connectors are used in the industrial or automotive industries, where high connection strength is required to ensure the stability of the line connection.

[0003] In the related art, the connector includes a shell having two mounting grooves, nuts are arranged on the mounting grooves, and protrusions are arranged on the groove walls of the mounting grooves, and the protrusions are located on the side of the nut away from the mounting grooves.

[0004] The protrusions are used to clamp and fix the nuts. Since the protrusions are usually formed by plastic bubbles, the structural strength of the protrusions themselves is low. When there is some shaking, the nut may damage the protrusions, causing the nut to detach from the installation slot, making the connector unreliable and the connector connection strength low. Summary of the invention

[0005] In order to improve the problem that the nut is easily detached from the installation groove, the present application provides a connector with high connection strength.

[0006] The present application provides a high connection strength connector, which adopts the following technical solution:

[0007] A connector with high connection strength comprises a shell, a mounting groove is provided on the shell, a nut is provided in the mounting groove, two fixing strips are provided on the shell, a limit block is provided on the shell, the limit block is located between the two fixing strips, a through hole is provided on the limit block for bolts to pass through, and two fixing grooves are provided on the limit block for the fixing strips to be inserted into; when the fixing strip is located in the fixing groove, the limit block is located on the side of the nut away from the bottom wall of the mounting groove.

[0008] By adopting the above technical solution, the limit block is located between the two fixing bars, and the fixing bar is inserted into the fixing groove, so that the fixing bar limits the limit block, and the limit block can be stably located on the side of the nut away from the bottom wall of the installation groove, so that the limit block can stably limit the nut from detaching from the bottom wall of the installation groove, and the connection between the nut and the shell is greatly increased in the force direction of the bolt and the nut, so that the connection between the nut and the shell can be more stable, thereby enhancing the structural strength of the connector.

[0009] Optionally, a card slot is provided on the limiting block, and a card block for inserting into the card slot is provided on the fixing bar; when the card block is located in the card slot, the fixing bar is located in the fixing slot.

[0010] By adopting the above technical solution, the card block is inserted into the card slot, so that the card block limits the limit block, allowing the limit block to be more stably located on the shell, preventing the limit block from detaching from the side away from the nut, and further increasing the connection strength between the limit block and the shell.

[0011] Optionally, a bevel is provided on the surface of the block facing the nut, the distance between the bevel and the nut gradually decreases along the direction from the fixing bar to another fixing bar, and the bevel abuts against the limit block.

[0012] By adopting the above technical solution, the distance between the card bevel and the nut is gradually reduced along the direction from the fixed bar to another fixed bar, so that the card bevel guides the installation of the limit block, reducing the difficulty of installing the limit block; at the same time, the card bevel abuts against the limit block, so that the contact area between the card block and the limit block is increased, further improving the connection strength between the card block and the limit block.

[0013] Optionally, a guide surface is provided on the limit block, and the directions of the guide surface and the fixing bar gradually increase from the fixing bar to another fixing bar.

[0014] By adopting the above technical solution, the direction of the guide surface and the fixing bar gradually increases from one fixing bar to another fixing bar, so that the fixing bar can be deformed along the guide surface, allowing the fixing bar to be smoothly inserted into the fixing groove, so as to achieve mutual fixation of the fixing bar and the limit block.

[0015] Optionally, a mounting spring sheet is provided on a side surface of the limiting block, the mounting spring sheet is deformed in a direction away from the limiting block, and the mounting spring sheet is located between the fixing bar and the limiting block.

[0016] By adopting the above technical solution, the installation spring sheet is deformed in the direction away from the limit block, and the installation spring sheet is located between the fixed bar and the limit block, so that the installation spring sheet can abut the fixed bar more stably. When the fixed bar is deformed due to severe shaking, the installation spring sheet can abut the fixed bar, allowing the installation spring sheet to apply force to the fixed bar, thereby avoiding displacement of the limit block between the two fixed bars and further reducing the possibility of movement of the limit block.

[0017] Optionally, a limiting spring piece is provided on the surface of the limiting block, the limiting spring piece is deformed in a direction away from the limiting block, and a limiting hole for the bolt to pass through is provided on the limiting spring piece.

[0018] By adopting the above technical solution, the limiting spring sheet is deformed in the direction away from the limiting block, and the bolt passes through the limiting hole. When the bolt and the nut are threadedly connected, the limiting spring sheet can further strengthen the connection strength between the bolt and the nut, so that the connection between the nut and the bolt can be more stable.

[0019] Optionally, a rotating bar is rotatably connected to the fixed bar, a stop block is provided on the rotating bar, and the rotating bar is located on the moving path of the installation spring sheet. When the limiting spring sheet is located between the stop block and the limiting block, the limiting hole is aligned with the through hole.

[0020] By adopting the above technical solution, the rotating bar is located on the moving path of the installation spring piece. When the limit block is installed between the two fixed bars, the installation spring piece drives the rotating bar to rotate, and the rotating bar drives the stop block to move, so that the limit spring piece is located between the stop block and the limit block, making it difficult for the limit spring piece to deform in the direction away from the limit block, so that the staff does not need to press the limit spring piece and then tighten the bolt, thereby reducing the staff's operating steps and reducing the difficulty of installing the bolt.

[0021] Optionally, a stop bevel is provided on the surface of the stop block away from the nut, and the distance between the stop bevel and the limiting spring piece gradually decreases from the direction from the fixing bar to another fixing bar, and the stop bevel is located on the moving path of the limiting spring piece.

[0022] By adopting the above technical solution, the distance between the stop bevel and the limiting spring piece gradually decreases along the direction from the fixed bar to the other fixed bar, and the stop bevel is located on the moving path of the limiting spring piece, so that the limiting spring piece can drive the stop bevel to drive the stop block to drive the rotating bar to move, so that the limiting spring piece can be smoothly located between the stop block and the limit block, so that the staff does not need to move the stop block first and then press the limiting spring piece.

[0023] Optionally, a receiving groove is provided on the limit block, the limit spring piece is located in the receiving groove, and a receiving bar for blocking the receiving groove is slidably connected to the limit block; when the receiving bar does not block the receiving groove, the installation spring piece can protrude from the receiving groove.

[0024] By adopting the above technical solution, the staff slides the accommodating bar so that the accommodating bar does not block the accommodating slot, so that the installation spring piece can protrude from the accommodating slot, and the installation spring piece can abut the rotating bar, so that the stop block limits the installation spring piece; by blocking the accommodating slot with the accommodating bar, the installation spring piece will not protrude from the accommodating slot, so that the installation spring piece will not affect the placement of the shell, avoiding the possibility of the installation spring piece being bent and damaged during transportation of the shell, thereby extending the service life of the installation spring piece.

[0025] Optionally, a sliding hole connected to the accommodating groove is provided on the limit block, and a sliding bar for inserting into the sliding hole is provided on the shell, and the accommodating bar is located on the moving path of the sliding bar; when the limit block is located between two fixed bars, the sliding bar is inserted into the accommodating groove, and at this time the mounting spring sheet can abut against the rotating bar.

[0026] By adopting the above technical solution, when the limit block is installed, the limit block is located between the two fixed bars, inserted into the sliding hole through the sliding bar, and the accommodating bar is located on the moving path of the sliding bar, so that the sliding bar can drive the accommodating bar to not block the accommodating groove, and the installing spring piece can abut the rotating bar, so that the stop block can limit the limit spring piece. The staff can observe whether the limit spring piece is restricted to know whether the limit block is installed in place. If the limit block is not installed in place, the accommodating bar still blocks the accommodating groove. At this time, the installing spring piece does not abut the rotating bar, so that the stop block fails to limit the movement of the limit spring piece, causing the limit spring piece to protrude.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The limit block is located between the two fixing bars, and the fixing bar is inserted into the fixing groove, so that the fixing bar limits the limit block, so that the limit block can be stably located on the side of the nut away from the bottom wall of the mounting groove, so that the limit block can stably limit the nut from detaching from the bottom wall of the mounting groove, and greatly increase the connection between the nut and the shell in the force direction of the bolt and the nut, so that the connection between the nut and the shell can be more stable, thereby enhancing the structural strength of the connector.

[0029] 2. The limiting spring piece is deformed in a direction away from the limiting block, and the bolt passes through the limiting hole. When the bolt and the nut are threadedly connected, the limiting spring piece can further strengthen the connection strength between the bolt and the nut, so that the connection between the nut and the bolt can be more stable.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] Example 1

[0038] This embodiment discloses a connector with high connection strength. Figure 1 and Figure 2 A connector with high connection strength includes a housing 1, two mounting grooves 11 are provided on the housing 1, and nuts are arranged in the mounting grooves 11. A threaded hole 12 is provided on the bottom wall of the mounting groove 11, and the threaded hole 12 is for a bolt to pass through.

[0039] Reference Figure 1 and Figure 2 Four fixing bars 2 are fixedly connected to the shell 1, two fixing bars 2 are located on one side of the shell 1, and the other two fixing bars 2 are located on the other side of the shell 1, and the two fixing bars 2 on the same side are distributed opposite to each other along the axis of the installation groove 11.

[0040] Reference Figure 1 and Figure 2 The housing 1 is provided with two stop blocks 3, which can be located between the two fixing bars 2 on the same side, and the surface of the stop block 3 is provided with a through hole 31 for the bolt to pass through. When the stop block 3 is located between the two fixing bars 2 on the same side, the through hole 31 is aligned with the threaded hole 12, and the nut is located between the bottom wall of the mounting groove 11 and the stop block 3.

[0041] Reference Figure 1 and Figure 2 , two fixing grooves 32 are provided on the surface of the limit block 3, and the two fixing grooves 32 are respectively located in the direction of the limit block 3 facing different fixing bars 2 on the same side, and the fixing bars 2 are inserted into the fixing grooves 32. Two guide surfaces 33 are provided on the surface of the limit block 3 where the fixing grooves 32 are provided, and the fixing groove 32 is located between the two guide surfaces 33, and the distance between the guide surface 33 and the fixing groove 32 gradually increases along the direction from the fixing bar 2 to another fixing bar 2 on the same side. When the limit block 3 is inserted between the two fixing bars 2, the fixing bars 2 are located on the moving path of the guide surfaces 33.

[0042] Reference Figure 2A block 21 is integrally formed on the surface of the fixing strip 2 facing the other fixing strip 2 on the same side, and a bevel 211 is provided on the surface of the block 21 facing the nut. The distance between the bevel 211 and the nut gradually decreases along the direction from the fixing strip 2 to the other fixing strip 2 on the same side. A slot 34 is provided on the surface of the fixing strip 2 for the block 21 to be inserted. When the limit block 3 is located between the two fixing strips 2 on the same side, the bevel 211 abuts against the wall of the slot 34, so that the contact area between the limit block 3 and the fixing strip 2 is increased, so that the limit block 3 and the fixing strip 2 can be more secure.

[0043] The implementation principle of Example 1 is as follows: the staff first places the nut in the installation groove 11, and then inserts the limiting block 3 between the two fixing bars 2 on the same side to limit the nut by the limiting block 3.

[0044] Example 2

[0045] Reference Figure 3 and Figure 4 The difference between this embodiment and the first embodiment is that the groove walls on opposite sides of the fixing groove 32 are provided with receiving grooves 35, and the receiving grooves 35 extend along the height direction of the limiting block 3. The bottom wall of the receiving groove 35 is fixedly connected with a mounting spring 351, and the mounting spring 351 is deformed in a direction away from the limiting block 3. When the limiting block 3 is installed between two fixing bars 2 on the same side, the two mounting springs 351 respectively abut against different fixing bars 2, and the mounting spring 351 is located between the fixing bar 2 and the limiting block 3.

[0046] Reference Figure 4 The side of the limit block 3 is provided with a sliding hole 36 connected to the receiving groove 35. There are two sliding holes 36, which are respectively connected to different receiving grooves 35. The limit block 3 is slidably connected with a receiving bar 361, which can completely block the opening of the receiving groove 35, and the receiving bar 361 is slidably connected in the sliding hole 36.

[0047] Reference Figure 4 and Figure 5 Four sliding bars 13 are fixedly connected to the surface of the housing 1, and the sliding bars 13 can be inserted into the sliding holes 36. Two sliding bars 13 are located on one side of the housing 1, and the other two sliding bars 13 are located on the other side of the housing 1. When the stop block 3 is installed, the sliding bars 13 are inserted into the sliding holes 36, and the sliding bars 13 push the receiving bars 361 to not block the receiving slots 35. At the same time, the sliding bars 13 do not block the receiving slots 35, so that the installation springs 351 protrude from the receiving slots 35.

[0048] Reference Figure 5A placement groove 22 is provided on the surface of the fixed bar 2 facing the other fixed bar 2 on the same side, a rotation bar 221 is rotatably connected in the placement groove 22, and a stopper 222 is fixedly connected on the surface of the rotation bar 221. The placement groove 22 is for the installation spring piece 351 to be inserted, and the rotation bar 221 is located on the moving path of the installation spring piece 351. When the installation spring piece 351 abuts against the rotation bar 221, the rotation bar 221 rotates, allowing the stopper 222 to protrude from the placement groove 22.

[0049] Reference Figure 4 and Figure 5 A limiting spring piece 37 is fixedly connected to the surface of the limiting block 3, and the limiting spring piece 37 is deformed in a direction away from the limiting block 3, and a limiting hole 371 for the bolt to pass through is opened on the surface of the limiting spring piece 37. When the stop block 222 protrudes out of the placement slot 22, the stop block 222 is located on the side of the limiting spring piece 37 away from the limiting block 3, and the limiting hole 371 is aligned with the through hole 31.

[0050] Reference Figure 4 and Figure 5 A stop bevel 223 is provided on the surface of the stop block 222 away from the nut, and the distance between the stop bevel 223 and the nut gradually decreases along the direction from the fixing bar 2 to the other fixing bar 2 on the same side, and the stop bevel 223 is located on the installation path of the limiting spring piece 37.

[0051] Reference Figure 4 and Figure 5 When the limit block 3 is installed in place and the limit spring piece 37 is located on the side of the stop block 222 away from the limit block 3, the limit spring piece 37 pushes the stop block 222 to move through the stop inclined surface 223, so that the limit spring piece 37 can contact the limit block 3. At this time, the installation spring piece 351 drives the rotating bar 221 to rotate, so that the rotating bar 221 drives the stop block 222 to be located on the side of the limit spring piece 37 away from the limit block 3, so that the stop block 222 limits the movement of the limit spring piece 37.

[0052] The implementation principle of Example 2 is as follows: the staff inserts the limit block 3 between the two fixed bars 2, and presses the limit spring piece 37 against the limit block 3, allowing the sliding bar 13 to drive the accommodating bar 361 to move, so that the installation spring piece 351 pops out, and the installation spring piece 351 drives the rotating bar 221 to rotate, so that the stop block 222 is located on the side of the limit spring piece 37 away from the limit block 3.
