Description

Technical Field

[0001] The utility model relates to a connector. Background Art

[0002] A connector is a device used to establish a current or signal connection between two active devices. Connectors are widely used, including connectors for electric brake boosters. Since electric brake boosters are electrically driven and lightweight devices that achieve vehicle braking, they require relatively small installation spaces. As a corresponding connector, a single connector often needs to integrate multiple terminals of different specifications, and the various connection holes are relatively dense, which makes it easy to cause interference. In addition, the overall structure is relatively complex, making it difficult to install the terminals. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model provides a connector for an electric brake booster which can reduce interference between different connection holes and is easy to install.

[0004] To achieve the above-mentioned purpose, the utility model provides a connector for an electric brake booster, comprising a shell, the shell comprising a circumferentially arranged rib, the shell comprising a convex portion located in the rib, the convex portion being provided with a locking piece and an end shell, the convex portion and one end of the end shell being snap-fitted and positioned to form a plurality of inner cavities for terminal installation, the locking piece being slidably arranged between the convex portion and the end shell, and the locking piece being able to slide to a position for forming or releasing a lock on the terminal in the inner cavity, a first connecting area being provided at the other end of the end shell, a plurality of first connecting ports being provided in the first connecting area, the plurality of first connecting ports being provided in two rows, and a spacing port being provided between two first connecting ports facing each other up and down.

[0005] The advantage of adopting the above technical solution is that a locking piece and an end shell are arranged on the convex part of the shell located in the retaining edge, so that the convex part and the end shell are snap-fitted and positioned to form an inner cavity between the two, and the sliding locking piece can form or release the positioning of the terminal by sliding to facilitate the installation of the terminal, and a first connection area is arranged at the other end of the end shell, so that the first connection ports are arranged in two rows in the first connection area, and then a spacing port is arranged between the two first connection ports opposite to each other in the upper and lower columns to avoid mutual interference between the first connection ports in the upper and lower columns.

[0006] The utility model can be further configured as follows: a plurality of second connection areas are further provided at the other end of the end shell, a plurality of second connection ports are provided in the second connection areas, and interval long grooves are provided between the first connection area and the second connection area and between adjacent second connection areas.

[0007] Through further configuration, a plurality of second connection areas with second connection ports are arranged at the other end of the end shell, and spacing ports are arranged between the two rows of first connection ports to avoid interference. Furthermore, spacing long grooves are arranged between different connection areas to better avoid interference between different connection ports.

[0008] The utility model can be further configured as follows: the locking piece is formed with a number of locking heads corresponding to the number of inner cavities, and the locking heads can slide into the corresponding inner cavities along with the locking piece.

[0009] Through further configuration, a number of locking heads are provided on the locking member corresponding to the number of inner cavities, and the locking heads that can slide into the corresponding inner cavities can form a limiting effect on the terminals in the inner cavities.

[0010] The utility model can be further configured as follows: the locking member includes two adjusting protrusions corresponding to the two ends of its sliding direction, the two adjusting protrusions can slide to the inner wall close to the retaining edge, and the retaining edge includes through holes corresponding to the positions of the adjusting protrusions.

[0011] Through further configuration, adjusting protrusions are provided on the locking member corresponding to the two ends of its sliding direction, and through holes are provided at the corresponding positions of the retaining edge. The staff can operate the adjusting protrusions through the through holes to adjust the position of the locking member to form or release the limit of the terminal in the inner cavity. The two adjusting protrusions are allowed to slide to the position close to the inner wall of the retaining edge. After the connector is completed, the corresponding connector can form a limit on the adjusting protrusion, thereby avoiding displacement of the locking member during use, which may lead to locking failure.

[0012] The utility model can be further configured as follows: the locking member includes a first clamping portion and a second clamping portion extending toward the end shell, the first clamping portion and the second clamping portion can form a clamp for the end shell, and a clamping block is provided on the first clamping portion, and the clamping block can form a contact limit with the end shell in the length direction of the first clamping portion as the locking member slides.

[0013] Through further configuration, a first clamping portion and a second clamping portion are provided on the locking member, and the first clamping portion and the second clamping portion are clamped on the upper and lower sides of the end shell to form a position limit between the locking member and the end shell, and a card block that can abut and limit the end shell is provided on the first clamping portion. This is because in order to ensure that the locking member slides between the protrusion and the end shell, a gap must be left between the protrusion and the end shell to facilitate its sliding, which can easily cause the terminal limited by the locking member to loosen. For this reason, an additional card block is provided, so that when the locking member forms a limit on the terminal, the card block and the end shell are clamped at the same time, which can effectively solve the problem of looseness.

[0014] The utility model can be further configured as follows: a mounting groove, a sealing cover and a card cover are provided at the rear end of the shell, the sealing cover and the card cover are successively installed in the mounting groove, a plurality of bayonet holes and elastic card heads are respectively provided on the peripheral sides of the mounting groove and the sealing cover, the card cover is card-engaged with the mounting groove, and an abutment portion for cooperating with the inner wall of the bayonet hole to clamp the elastic card head is provided on the card cover.

[0015] Through further configuration, a mounting groove, a sealing cover and a card cover are provided at the rear end of the shell, and the sealing cover and the card cover are successively installed in the mounting groove to form a seal and positioning for the terminals therein, wherein a bayonet and an elastic clamp are respectively provided on the surrounding sides of the mounting groove and the sealing cover. Under normal circumstances, the elastic clamp can pass through or enter the bayonet through the elasticity of the elastic clamp, and the abutment portion on the card cover cooperates with the inner wall of the bayonet to form a clamping part for the elastic clamp, so that when the card cover is installed, the elastic clamp cannot pass through or enter the bayonet through deformation, so that the sealing cover is convenient for disassembly and assembly, and the positioning effect is also better.

[0016] The utility model can be further configured as follows: a long groove located at the peripheral side is formed between the convex portion and the end shell, and the long groove is provided for the sealing ring to be mounted.

[0017] Through further configuration, a long groove for the sealing ring to be mounted is provided between the convex portion and the end shell, so that the sealing ring can be better positioned on the basis of effectively ensuring the seal, thereby avoiding the situation where it comes out due to plugging and unplugging or high internal pressure.
