Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to an assembled wire harness connector housing. Background Art

[0002] A wire harness connector is a type of terminal. The connection between wire harnesses, or between a wire harness and an electrical component, generally uses a wire harness connector. An automotive wire harness connector is an important component for connecting various electrical and electronic devices in an automobile, and its main function is to prevent the wire harness from disconnecting from the electronic device during the driving of the automobile.

[0003] Most of the housings of traditional wire harness connectors are integrally formed. To obtain an integrally formed housing, an integral injection molding process needs to be used for manufacturing. Due to the use of an integrally formed housing, when the wire harness terminals on the housing are damaged or misinstalled, they cannot be disassembled and assembled, resulting in the inability to replace the wire harness terminals, and causing the entire connector to be scrapped. Summary of the Utility Model

[0004] Aiming at the above-mentioned defects existing in the prior art, the purpose of the utility model is to provide an assembled wire harness connector housing that can be disassembled and assembled, can be conveniently replaced, and can reduce the use cost.

[0005] The technical solution adopted by the utility model to solve its technical problems is that an assembled wire harness connector housing includes an outer housing, an inner housing, and a locking plate. The lower end and the upper end of the outer housing are respectively provided with a first installation cavity and a second installation cavity. The first installation cavity is used for installing an external plug. A plurality of first jacks are communicated between the first installation cavity and the second installation cavity. The first jacks are used for installing contact terminals. The inner housing is detachably fixed in the second installation cavity. A plurality of second jacks are penetrated through the inner housing. The second jacks are arranged corresponding to the first jacks and are used for installing wire harness terminals. An installation groove radially penetrating through the second jacks is further provided on the front side wall surface of the inner housing. The locking plate is detachably fixed in the installation groove. An avoidance hole is provided on the locking plate. The avoidance hole is arranged corresponding to the second jacks. Locking holes are further formed at corresponding positions on the side wall surface of the avoidance hole. After the locking plate is inserted in place in the installation groove, the locking holes lock the wire harness terminals in the second jacks.

[0006] Advantages of adopting the above technical solution: Since the outer shell and the inner shell are separately arranged, the inner shell can be disassembled from the second installation cavity, so that the inner shell can be separated from the outer shell. The second installation cavity is formed at the upper end of the outer shell, and the disassembly and assembly of the inner shell are convenient. By setting the locking plate, the locking or unlocking of the wire harness terminals on the inner shell is realized through the position change of the avoidance holes and locking holes on the locking plate relative to the second jacks, making the connection more stable. At the same time, the disassembly, assembly and replacement of the wire harness terminals and the inner shell are realized. The setting of the above structure solves the problem that the integrally formed shell is inconvenient for disassembly and assembly, resulting in the inability to replace the wire harness terminals and the scrapping of the entire connector, effectively reducing the use cost.

[0007] Further, elastic hooks extending downward are connected to the top of the left and right side wall surfaces of the inner shell, and mounting bayonets are penetrated through the left and right inner wall surfaces of the second installation cavity, and the bayonet portions of the mounting bayonets are engaged with the hook portions of the elastic hooks.

[0008] Advantages of adopting the above technical solution: When the wire harness terminals need to be replaced, the user can insert a substance such as a cushion block into the mounting bayonet and release the locking state between the bayonet portion of the elastic hook and the mounting bayonet, so that the inner shell can be disassembled relative to the outer shell. The structure is simple and the design is reasonable.

[0009] Further, the elastic hooks are arranged to be inclined outward, and receiving grooves are correspondingly arranged on the left and right inner wall surfaces of the second installation cavity, and the mounting bayonets are arranged in the receiving grooves.

[0010] Advantages of adopting the above technical solution: By setting the elastic hooks to be inclined outward, the elastic hooks have stronger elastic force, so that the connection with the mounting bayonet will be more firm. The setting of the receiving grooves limits the positions of the elastic hooks, effectively preventing the disconnection of the connection between the elastic hooks and the mounting bayonets due to vibration. The connection will be more stable and the structural design is reasonable.

[0011] Further, a set of clamping protrusions are arranged on the upper and lower wall surfaces of the locking plate, and the clamping protrusions are used to form close contact with the inner wall surface of the installation groove to cooperate with the locking holes to lock the wire harness terminals in the second jacks.

[0012] Advantages of adopting the above technical solution: Through the setting of the clamping protrusions, the locking plate will not move in position after locking the wire harness terminals, and the locking is more stable. The structural design is also simple and reasonable.

[0013] Further, a hollow structure is arranged at intervals on the rear wall surface of the inner shell, and the hollow structure cooperates with the installation groove.

[0014] Advantages of adopting the above technical solution: The user can insert a substance such as a spacer into the installation groove through the hollow structure to push the locking plate. As the locking plate moves, the locking of the wire harness terminal by the locking hole is released, and the tight contact between the clamping bump and the inner wall surface of the installation groove is also released, and the avoidance hole is aligned with the second jack again, so that the unlocking of the lock can be completed, and the wire harness terminal can be replaced.

[0015] Further, a guiding slot is provided at the bottom of the front or rear outer wall surface of the inner housing, and a guiding plug post is correspondingly provided on the corresponding inner wall surface of the second installation cavity, and the guiding plug post is inserted into the guiding slot.

[0016] Advantages of adopting the above technical solution: Through the cooperation of the guiding slot and the guiding plug post, the misalignment of the inner housing and the outer housing is prevented, and the stability of the cooperation is ensured, so that the contact effect between the contact terminal and the wire harness terminal is good.

[0017] Further, a direction identification block is provided at the top of the front or rear outer wall surface of the inner housing, and an avoidance groove communicating with the second installation cavity is provided at the corresponding position of the top of the outer housing, and the avoidance groove cooperates with the direction identification block.

[0018] Advantages of adopting the above technical solution: By providing the direction identification block, the installation direction of the inner housing can be quickly identified, so that the installation efficiency is higher, and misalignment is also avoided. The setting of the avoidance groove makes the inner housing not overly exposed outside the outer housing after installation, and the assembled product is beautiful.

[0019] Further, supporting rib columns are spacedly provided on the front and rear inner wall surfaces of the second installation cavity, and the supporting rib columns abut against the front and rear outer wall surfaces of the inner housing.

[0020] Advantages of adopting the above technical solution: By providing the supporting rib columns that abut against the inner wall surface of the inner housing, the cooperation between the inner housing and the second installation cavity of the outer housing is more stable, and the structural design is reasonable.

Specific embodiments

[0028] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model and / or the prior art, the specific embodiments of the present utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other embodiments can also be obtained. Additionally, the terms related to orientation only represent the relative positional relationship between components, rather than the absolute positional relationship.

[0029] Please refer to Figures 1 to 6As shown in the figure, an assembled wire harness connector housing includes an outer housing 1, an inner housing 2, and a locking plate 3. The lower end and the upper end of the outer housing 1 are respectively provided with a first installation cavity 4 and a second installation cavity 5. The first installation cavity 4 is used for installing an external plug. A plurality of first jacks 6 are communicated between the first installation cavity 4 and the second installation cavity 5. The first jacks 6 are used for installing contact terminals. The inner housing 2 is detachably fixed in the second installation cavity 5. A plurality of second jacks 7 are provided through the inner housing 2. The second jacks 7 are arranged corresponding to the first jacks 6 and are used for installing wire harness terminals. An installation groove 8 radially penetrating the second jacks 7 is further provided on the front side wall surface of the inner housing 2. The locking plate 3 is detachably fixed in the installation groove 8, and an avoidance hole 9 is provided on the locking plate 3. The avoidance hole 9 is arranged corresponding to the second jacks 7. More specifically, during installation, by aligning the avoidance hole 9 with the second jacks 7, the wire harness terminals can pass through. A locking hole 10 is further formed at a corresponding position on the side wall surface of the avoidance hole 9. After the locking plate 3 is inserted in place in the installation groove 8, the locking hole 10 locks the wire harness terminals in the second jacks 7. More specifically, after the wire harness terminals are inserted, by further inserting the locking plate 3 along the inside of the installation groove 8, the locking hole 10 can be moved to the locking position to complete the locking. On the contrary, after locking, by simply moving the locking plate in the reverse direction of withdrawing from the installation groove 8, the locking of the locking hole 10 can be released. In the above structure, since the outer housing 1 and the inner housing 2 are separately provided, by disassembling the inner housing 2 from the second installation cavity 5, the separation of the inner housing 2 and the outer housing 1 can be realized. Moreover, the second installation cavity 5 is formed at the upper end of the outer housing 1, and the disassembly and assembly of the inner housing 2 are also convenient. By setting the locking plate 3, through the position change of the avoidance hole 9 and the locking hole 10 on the locking plate 3 relative to the second jacks 7, the locking or unlocking of the wire harness terminals on the inner housing 2 is realized, making the connection more stable. At the same time, the detachable replacement of the wire harness terminals and the inner housing 2 is also realized, thus solving the problem that the integrally formed housing is inconvenient for disassembly and assembly, resulting in the inability to replace the wire harness terminals and the scrapping of the entire connector, effectively reducing the use cost.

[0030] In this embodiment, elastic hooks 11 extending downward are further connected to the top parts of the left and right side wall surfaces of the inner housing 2. Installation notches 12 are provided through the left and right inner wall surfaces of the second installation cavity 5. The installation notches 12 are engaged with the hook parts of the elastic hooks 11. In the above structure, when the wire harness terminals need to be replaced, the user can insert a substance such as a cushion block into the installation notches to release the locking state between the hook parts of the elastic hooks 11 and the installation notches 12, so that the inner housing 2 can be disassembled relative to the outer housing 1. The structure is simple and the design is reasonable.

[0031] In this embodiment, the elastic catch 11 is arranged to incline outwards, and receiving grooves 13 are correspondingly provided on the left and right inner wall surfaces of the second installation cavity 5. The installation bayonet 12 is arranged in the receiving groove 13. By arranging the elastic catch 11 to be inclined outwards, the elastic catch 11 has a strong elastic force, so that the connection with the installation bayonet 12 will be more firm. The arrangement of the receiving groove 13 limits the position of the elastic catch 11, effectively preventing the disconnection of the connection between the elastic catch 11 and the installation bayonet 12 due to vibration. The connection will be more stable and the structural design is reasonable.

[0032] In this embodiment, a set of clamping protrusions 14 are provided on the upper and lower wall surfaces of the locking plate 3. The clamping protrusions 14 are used to form close contact with the inner wall surface of the installation groove 8 to cooperate with the locking hole 10 to lock the wire harness terminal in the second jack 7. Through the arrangement of the clamping protrusions 14, after the locking plate 3 locks the wire harness terminal, the phenomenon of position movement will no longer occur, the locking is more stable, and the structural design is also simple and reasonable. It should be noted that when the avoidance hole 9 is aligned with the second jack 7, the clamping protrusion 14 will move to the opening of the installation groove 8. When the avoidance hole 9 continues to move in the same side, while the locking hole 10 gradually reaches the position, the clamping protrusion 14 will also gradually move into the installation groove 8. That is to say, the clamping protrusion 14 and the locking hole 10 are synchronously matched, and the rear wall surface of the clamping protrusion 14 is arranged as an inclined surface.

[0033] In this embodiment, a hollow structure 15 is provided at intervals on the rear wall surface of the inner housing 2. The hollow structure 15 cooperates with the installation groove 8. With the above structure, the user can insert a substance such as a cushion block into the installation groove 8 through the hollow structure 15 to push the locking plate 3. As the locking plate 3 moves, the locking of the wire harness terminal by the locking hole 10 is released, and the close contact between the clamping protrusion 14 and the inner wall surface of the installation groove 8 is also released, and the avoidance hole 9 is aligned with the second jack 7 again, so that the locking can be released, and the wire harness terminal can be replaced.

[0034] In this embodiment, a guide slot 16 is provided at the bottom of the front or rear outer wall surface of the inner housing 2. A guide pin 17 is correspondingly provided on the corresponding inner wall surface of the second installation cavity 5. The guide pin 17 is inserted into the guide slot 16. Through the cooperation of the guide slot 16 and the guide pin 17, the misassembly of the inner housing 2 and the outer housing 1 is prevented, and the stability of the cooperation is ensured, so that the contact effect between the contact terminal and the wire harness terminal is good.

[0035] In this embodiment, a direction recognition block 18 is provided at the top of the front or rear outer wall surface of the inner housing 2, and an avoidance groove 19 communicating with the second installation cavity 5 is provided at the corresponding position at the top of the outer housing 1. The avoidance groove 19 cooperates with the direction recognition block 18. By providing the direction recognition block 18, the installation direction of the inner housing 2 can be quickly recognized, making the installation efficiency higher and avoiding misinstallation. The setting of the avoidance groove 19 makes the inner housing 2 not overly exposed outside the outer housing 1 after installation, and the assembled product is beautiful.

[0036] In this embodiment, support ribs 20 are provided at intervals on the front and rear inner wall surfaces of the second installation cavity 5. The support ribs 20 abut against the front and rear outer wall surfaces of the inner housing 2. By providing the support ribs 20 that abut against the wall surface of the inner housing 2, the cooperation between the inner housing 2 and the second installation cavity 5 of the outer housing 1 is more stable, and the structural design is reasonable.

[0037] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can be made, and all should be regarded as belonging to the protection scope of the present invention.
