Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a wire harness connector with an aircraft buckle. Background Art

[0002] In various electronic products, including devices containing electronic equipment and vehicles, a wire harness terminal structure is required for line connection. Existing wire harness terminals need to be connected to a plastic housing in advance. During use, the male and female plastic housings are fastened to each other so that the male and female terminals inside the plastic housing are plugged in to achieve conduction. The existing connection and limiting structure between the terminal and the plastic housing is achieved by setting a hook on the terminal and a terminal hanging platform on the plastic housing that cooperates with the hook. When the terminal is inserted into the plastic housing, the hook on the terminal hooks the terminal hanging platform to achieve limiting. The terminal is made of a metal material that is easy to deform, and the hook is made of the same material as the terminal. When the male and female terminals are plugged in, it is easy to cause deformation of the terminal hook and other parts of the terminal, resulting in the terminal being easily detached from the plastic housing or displaced inside the plastic housing, further leading to poor contact between the male and female terminals and poor stability. Especially for waterproof wire harness connectors, the existing waterproof wire harness connectors have poor waterproof performance, and the stability is poor when the wire harness connector is fixed to the fitting and is prone to falling off, further causing the terminal to fall off and the circuit to be interrupted. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a wire harness connector with an aircraft buckle. By setting an integrally connected aircraft buckle on the connector housing, the stability of the overall fixation of the wire harness connector to the assembly position is improved. By setting a waterproof structure between the connector housing and the connector plug and on the outer side ends of the connector housing and the connector plug, the connection tightness between the connector housing and the connector plug is strengthened, and the waterproof performance is improved. By setting an inclined terminal hanging platform, excessive deformation during the plugging of the terminal is prevented, and the terminal is prevented from detaching from the female end placement hole or the male end placement hole, effectively reducing the failure of poor contact and improving the stability of the terminal connection. The utility model is applicable to the technical field of connectors.

[0004] The technical solution adopted by the utility model is as follows: A wire harness connector with an aircraft buckle includes a connector housing and a connector plug. The inner side end of the connector housing is provided with a connection cavity for the connector plug to be inserted and connected. A male end placement hole is provided inside the connector housing, and a female end placement hole is provided inside the connector plug. It is characterized in that an aircraft buckle is integrally connected to the side wall of the connector housing. The wire harness connector is fixed to the fitting through the aircraft buckle to achieve the overall position fixation, and the integral connection of the aircraft buckle and the connector housing improves the stability of the overall position fixation of the wire harness connector.

[0005] Hook members are provided on opposite side walls of the connector insert block, and hook limiting bumps for cooperating with the hook members for limiting are provided on opposite side walls of the connector housing correspondingly. A waterproof flange is provided on the outer wall of the connector insert block. When the connector insert block is inserted into the connector housing, the waterproof flange wraps the edge of the inner side end of the connector housing. The design of the double hook members makes the connection between the connector housing and the connector insert block more stable, further enabling the four peripheral edges of the waterproof flange to stably wrap the edge of the inner side end of the connector housing, thereby improving the waterproof effect.

[0006] Waterproof covers are connected to the outer side ends of the connector housing and the connector insert block. A wire harness port corresponding to the male end placement hole or the female end placement hole is provided on the waterproof cover. A lock is provided on the waterproof cover for fixing the waterproof cover to the outer side end of the connector housing or the connector insert block. A lock limiting bump for cooperating with the lock for limiting is provided on the side wall of the outer side end of the connector housing or the outer side end of the connector insert block correspondingly. A rubber pad is placed inside the waterproof cover. A constricting rubber hole corresponding to the wire harness port is provided on the rubber pad. The connector housing has, from the outside to the inside, a wire harness port, a constricting rubber hole, and a male end placement hole that correspond one by one. The male terminal of the connecting wire is inserted into the male end placement hole from the wire harness port, and the constricting rubber hole tightly wraps the wire to achieve the waterproof function at the outer side end of the connector housing; the connector insert block has, from the outside to the inside, a wire harness port, a constricting rubber hole, and a female end placement hole that correspond one by one. The female terminal of the connecting wire is inserted into the female end placement hole from the wire harness port, and the constricting rubber hole tightly wraps the wire to achieve the waterproof function at the outer side end of the connector insert block.

[0007] A terminal hanging platform for restricting the male terminal from being pulled out is provided on the inner wall of the male end placement hole. The terminal hanging platform is inclined at an acute angle relative to the inner wall of the male end placement hole. The barb on the male terminal is not easily deformed under force, thereby effectively preventing the male terminal from falling off under force.

[0008] A terminal hanging platform for restricting the female terminal from being pulled out is provided on the inner wall of the female end placement hole. The terminal hanging platform is inclined at an acute angle relative to the inner wall of the female end placement hole. The barb on the female terminal is not easily deformed under force, thereby effectively preventing the female terminal from falling off under force.

[0009] The beneficial effects of this solution are as follows: The aircraft buckle integrally connected to the connector housing improves the stability of the overall fixing of the wire harness connector to the assembly position. The double terminal hanging platforms and the waterproof flange between the connector housing and the connector insert block improve the waterproof performance between the connector housing and the connector insert block. The waterproof covers and rubber pads provided at the outer side ends of the connector housing and the connector insert block improve the waterproof performance at the outer side ends of the connector housing and the connector insert block. The setting of the inclined terminal hanging platform prevents excessive deformation during the process of terminal insertion and removal and prevents the terminal from detaching from the female end placement hole or the male end placement hole, effectively reducing the fault of poor contact and improving the stability of terminal connection.

Specific Embodiments

[0021] The present utility model provides a wire harness connector with an aircraft buckle, which is applicable to the technical field of connectors. The present utility model can be implemented in the following manner:

[0022] As Figures 1-6 shown: A wire harness connector with an aircraft buckle includes a connector housing 1 and a connector insert block 2. The inner end of the connector housing 1 is provided with a connection cavity 12 for the connector insert block 2 to be inserted and connected. Inside the connector housing 1, there is a male terminal placement hole 13, and inside the connector insert block 2, there is a female terminal placement hole 23. It is characterized in that an aircraft buckle 3 is integrally connected to the side wall of the connector housing 1. The wire harness connector is fixed on the fitting through the aircraft buckle 3 to realize the overall position fixation. The integral connection of the aircraft buckle 3 and the connector housing 1 improves the stability of the overall position fixation of the wire harness connector.

[0023] On both opposite side walls of the connector insert block 2, there are hooks 21 provided. Correspondingly, on both opposite side walls of the connector housing 1, there are hook limiting bumps 11 that cooperate with the hooks 21 for limiting. On the outer wall of the connector insert block 2, there is a waterproof flanging 22 provided. When the connector insert block 2 is inserted into the connector housing 1, the waterproof flanging 22 wraps around the edge of the inner end of the connector housing 1. The design of the double hooks 21 makes the connection between the connector housing 1 and the connector insert block 2 more stable, and further enables the four peripheral edges of the waterproof flanging 22 to stably wrap around the edge of the inner end of the connector housing 1, thereby improving the waterproof effect.

[0024] As Figures 7-8 shown: On the outer ends of both the connector housing 1 and the connector insert block 2, there is a waterproof cover 6 connected. On the waterproof cover 6, there is a wire harness port 61 corresponding to the male terminal placement hole 13 or the female terminal placement hole 23. On the waterproof cover 6, there is a buckle 62 for fixing the waterproof cover 6 on the outer end of the connector housing 1 or the connector insert block 2. Correspondingly, on the side wall of the outer end of the connector housing 1 or the outer end of the connector insert block 2, there is a buckle limiting bump 8 that cooperates with the buckle 62 for limiting. Inside the waterproof cover 6, there is a rubber pad 7 placed. On the rubber pad 7, there is a constricted rubber hole 71 corresponding to the wire harness port 61. From the outside to the inside of the connector housing 1, there are respectively the wire harness port 61, the constricted rubber hole 71, and the male terminal placement hole 13 that correspond one by one. The male terminal 4 of the connecting wire is inserted into the male terminal placement hole 13 from the wire harness port 61, and the constricted rubber hole 71 tightly wraps the wire to achieve the waterproof function at the outer end position of the connector housing 1; from the outside to the inside of the connector insert block 2, there are respectively the wire harness port 61, the constricted rubber hole 71, and the female terminal placement hole 23 that correspond one by one. The female terminal 5 of the connecting wire is inserted into the female terminal placement hole 23 from the wire harness port 61, and the constricted rubber hole 71 tightly wraps the wire to achieve the waterproof function at the outer end position of the connector insert block 2.

[0025] On the inner wall of the male terminal placement hole 13, there is a terminal hanging platform 9 for restricting the extraction of the male terminal 4. The terminal hanging platform 9 is inclined at an acute angle relative to the inner wall of the male terminal placement hole 13. During the process of the male terminal 4 of the connecting wire passing through the wire harness port 61 and the constricted rubber hole 71 and inserting into the male terminal placement hole 13, the barb 41 on the male terminal 4 is prone to shrinkage deformation due to the friction between the constricted rubber hole 71 and the inner wall. When the male terminal 4 is inserted into the male terminal placement hole 13, the barb 41 is hooked on the terminal hanging platform 9 and under the action of the inclined surface, when the male terminal 4 is forced outward, the barb 41 will fall into the low position of the terminal hanging platform 9 along the trend, thereby effectively preventing the male terminal 4 from falling off due to force.

[0026] On the inner wall of the female terminal placement hole 23, there is a terminal hanging platform 9 that restricts the extraction of the female terminal 5. The terminal hanging platform 9 is inclined at an acute angle relative to the inner wall of the female terminal placement hole 23. During the process of inserting the female terminal 5 connected to the wire through the wire harness port 61 and the tightening rubber hole 71 into the female terminal placement hole 23, the barb 41 on the female terminal 5 is prone to shrinkage deformation due to the friction between the tightening rubber hole 71 and the inner wall. When the female terminal 5 is inserted into the female terminal placement hole 23, the barb 41 is placed on the terminal hanging platform 9 and, under the action of the inclined surface, when an external force is applied to the female terminal 5, the barb 41 will fall into the lower position of the terminal hanging platform 9 along the trend, thereby effectively preventing the female terminal 5 from falling off due to force.
