Description

Technical Field

[0001] This utility model relates to the field of electronic wire harness technology, specifically a reliably connected combined electronic wire harness. Background Technology

[0002] In the fields of electronic equipment and vehicle manufacturing, electronic wire harnesses, as a key component connecting different electrical components, play a vital role in signal transmission and power distribution. In practical applications, to meet complex layouts and diverse installation requirements, multiple electronic wire harnesses are often combined and connected. Currently, commonly used connection methods in the industry include, but are not limited to, threaded connections and mechanical fixing methods such as snap-fit ​​connections.

[0003] However, during long-term use, the aforementioned traditional connection method has revealed some problems. In particular, after repeated plugging and unplugging operations, the connector is prone to loosening, which may not only increase contact resistance and cause unstable signal transmission, but also potentially lead to disconnection, affecting the basic functionality and reliability of the electronic wire harness. To address these issues, this invention proposes a reliably connected combined electronic wire harness. Utility Model Content

[0004] The purpose of this invention is to provide a reliably connected combined electronic wire harness to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution:

[0006] A securely connected combined electronic wire harness includes a wire harness body with several conductors built in and a connector snapped between two wire harness bodies. The end face of the wire harness body is provided with a connector hole. A conductive pin that is electrically connected to the conductor is elastically disposed in the connector hole by a first spring. A conductive rod is embedded and fixed in the connector. The conductive rod is provided with an insertion hole that matches the tip of the conductive pin.

[0007] Optionally, the conductive pin is connected to the conductor via a flexible wire, and the first spring is located between the conductive pin and the conductor and sleeved on the outside of the flexible wire.

[0008] Optionally, a snap-fit ​​structure is provided between the connector and the wire harness body. The snap-fit ​​structure includes two hooks on the connector, which are elastically connected by a second spring. A snap hole is provided on the wire harness body located at the connector hole to engage with the hooks.

[0009] Optionally, each of the hooks includes a hook rod and a pressing rod. The connector is provided with a mounting hole for mounting the hook rod. The second spring is located between the two hook rods. Both ends of the hook rod are provided with hook-shaped portions that engage with the hook holes. The first end of the pressing rod is fixed to the middle of the hook rod, and the second end movably passes through the connector and extends to the outer wall of the connector.

[0010] Optionally, a recess is formed on the outer wall of the connector, and the second end of the pressing rod is placed in the recess.

[0011] Optionally, a first positioning groove is provided on the outer wall of the wire harness body, and a second positioning groove is provided on the outer wall of the connector.

[0012] Optionally, a sealing ring is provided inside the insertion hole, and the outer walls at both ends of the connector abut against the inner side of the sealing ring when the connector is inserted into the insertion hole.

[0013] Compared with the prior art, this utility model provides a reliably connected combined electronic wire harness, which has the following beneficial effects:

[0014] 1. This utility model connects two wire harness bodies by inserting a connector into a connector hole. After connection, the two wire harness bodies are connected by a conductive rod. Since the conductive pin will always be pressed against the conductive rod under the first spring, a stable and reliable electrical connection relationship can be formed between the two wire harness bodies.

[0015] 2. By setting a first positioning groove and a second positioning groove, this utility model can determine whether the conductive pin and the insertion hole are aligned when connecting the connector to the wire harness body, thereby ensuring that the conductive pin can be accurately inserted into the insertion hole.

[0016] 3. This utility model has a recess formed on the outer wall of the connector, and the second end of the pressing rod is placed in the recess. This can prevent the connection between the connector and the wire harness body from being accidentally disconnected due to accidental contact with the pressing rod. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1 to 6 According to an embodiment of the present invention, a reliably connected combined electronic wire harness is provided, including a wire harness body 1 with a plurality of conductors 2 built in and a connector 3 snapped between two wire harness bodies 1. The end face of the wire harness body 1 is provided with a plug hole 102. A conductive pin 5 electrically connected to the conductor 2 is elastically disposed in the plug hole 102 by a first spring 4. A conductive rod 6 is embedded and fixed in the connector 3. The conductive rod 6 is provided with an insertion hole 60 that matches the tip of the conductive pin 5.

[0026] The combined electronic wire harness with the above structure has a reliable connection. The two wire harness bodies 1 are connected by inserting the connector 3 into the connector hole 102. After connection, the two wire harness bodies 1 are connected by the conductive rod 6. Since the conductive pin 5 will always be pressed against the conductive rod 6 under the first spring 4, a stable and reliable electrical connection relationship can be formed between the two wire harness bodies 1.

[0027] In this exemplary embodiment, the conductive pin 5 and the conductor 2 are connected by a flexible wire 7, and the first spring 4 is located between the conductive pin 5 and the conductor 2 and is sleeved on the outside of the flexible wire 7. This arrangement allows for two advantages: firstly, the flexible wire 7 enables conductivity between the conductive pin 5 and the conductor 2, and the relative positions between the conductive pin 5 and the conductor 2 can vary within a certain range; secondly, the flexible wire 7 restricts the position of the first spring 4, ensuring that the first spring 4 is always located between the conductive pin 5 and the conductor 2.

[0028] In this exemplary embodiment, a snap-fit ​​structure is provided between the connector 3 and the wire harness body 1. The snap-fit ​​structure includes two hooks 8 provided on the connector 3, which are elastically connected by a second spring 9. A locking hole 100 is provided on the wire harness body 1 located at the connector hole 102 to engage with the hooks 8. The snap-fit ​​between the hooks 8 and the locking hole 100 facilitates the assembly and disassembly of the connector 3 and the wire harness body 1. Specifically, each hook 8 includes a locking rod 80 and a pressing rod 81. The connector 3 is provided with a mounting hole 32 for mounting the locking rod 80. The second spring 9 is located between the two locking rods 80. Both ends of the locking rod 80 are provided with hook-shaped portions 800 that engage with the locking hole 100. The first end of the pressing rod 81 is fixed to the middle of the locking rod 80, and the second end movably passes through the connector 3 and extends to the outer wall of the connector 3. In use, the locking relationship between the locking rod 80 and the locking hole 100 can be released by squeezing the pressing rod 81, thereby facilitating the disassembly of the connector 3 and the wire harness body 1.

[0029] In order to prevent the connection between the connector 3 and the wire harness body 1 from being accidentally disconnected due to accidental contact with the squeezing bar, in this exemplary embodiment, a recess 30 is formed on the outer wall of the connector 3, and the second end of the squeezing bar 81 is placed in the recess 30.

[0030] In this exemplary embodiment, a first positioning groove 101 is provided on the outer wall of the wire harness body 1, and a second positioning groove 31 is provided on the outer wall of the connector 3. With this configuration, when the connector 3 is connected to the wire harness body 1, the first positioning groove 101 and the second positioning groove 31 can be used to determine whether the conductive pin 5 and the insertion hole 60 are aligned, thereby ensuring that the conductive pin 5 can be accurately inserted into the insertion hole 60.

[0031] In this exemplary embodiment, a sealing ring 10 is provided inside the plug hole 102, and the outer walls at both ends of the plug 3 abut against the inner side of the sealing ring 10 when the plug 3 is inserted into the plug hole 102. By providing the sealing ring 10 inside the plug hole 102, the sealing performance at the connection between the plug 3 and the wire harness body 1 can be improved, preventing moisture from entering the plug hole 102 and avoiding oxidation of conductive structures such as the conductive pin 5 and conductive rod 6 by moisture, thereby further improving the contact stability after the electronic wire harness is assembled and connected.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
