Description

Technical Field

[0001] This utility model relates to the field of electronic wire harness technology, specifically an electronic wire harness that is easy to plug in and unplug. Background Technology

[0002] Electronic wire is short for internal wire of electrical equipment. There are three main series of electronic wires on the market: UL standard, 3C standard and VDE standard. In China, electronic wire manufacturers mainly focus on the 3C and UL standards. Regardless of whether it is UL standard, 3C standard or VDE standard electronic wire, its current carrying capacity is mainly low voltage. Unlike cable, electronic wire harness is a group of metal wires and cable are bundled together to realize the signal transmission or power connection between the equipment. It is the wiring component that connects various electrical devices in the connection circuit of various equipment. It generally consists of insulating sheath, terminal block, wire and insulating wrapping material.

[0003] According to the search results, Chinese patent document, publication number CN222530930U, discloses an electronic wire harness with a magnetic connection structure. A magnetic socket 6 pushes a locking post 16, which in turn compresses a return spring 15 via a limiting block 14. A cavity 12 provides the travel stroke for the push rod 13. When the magnetic plug 4 reaches the designated position, it is fixed to the magnetic socket 6 via a slot 8. The magnetic socket 6 magnetically connects the wire harness connector 5 to the connector 1. Simultaneously, the return spring 15 uses tension to push the locking post 16 outwards, further ensuring the stability of the magnetic connection by using the locking post 16 in conjunction with the slot 8 to fix the magnetic socket 6. After connection, the first metal contact 9 connects to the second metal contact 17 for power and signal transmission. Disconnection only requires forcefully pulling out the wire harness connector 5.

[0004] When disconnecting the aforementioned electronic wire harness, the wire harness connector needs to be pulled out forcefully. This makes it easy to insert the electronic wire harness but difficult to pull it out. Furthermore, pulling it out forcefully can easily cause irreversible damage to the wire harness connector. In addition, pulling it out forcefully can also cause excessive friction of the contacts and peeling off of the oxide layer. Even if it is reinserted later, poor contact may occur. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an electronic wire harness that is easy to plug in and unplug.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electronic wire harness that is easy to insert and remove, including a connector. The connector has locking mechanisms symmetrically arranged at both ends. Each locking mechanism includes an outer cylinder, an inner cylinder, a sleeve, a locking rod, a moving part, and a spring. The inner cylinder is located at the middle of the bottom of the outer cylinder. The sleeve is inserted into the outer cylinder from the top and is positioned above the inner cylinder. The locking rod passes through the bottom of both the inner and outer cylinders sequentially. The moving part passes through the locking rod and the inner cylinder sequentially and extends to the outside of the inner cylinder. A limiting piece is connected to the top of the locking rod, and the spring is connected between the limiting piece and the inner top wall of the sleeve.

[0007] As described above, guide blocks are symmetrically arranged on the inner wall of one end of the sleeve that is embedded in the outer cylinder, and an upwardly inclined guide slope is provided on the adjacent side of the two guide blocks. Both ends of the moving part are slidably engaged with the guide slope.

[0008] As described above, a protective cover is provided on the outside of the locking mechanism. The protective cover is a hollow structure with one end open, and the end of the protective cover away from the opening is connected to the connector.

[0009] As described above, the top of the connector is provided with a slot, and positioning grooves are symmetrically provided on both sides of the top of the connector near the slot.

[0010] As described above, a wire harness connector is inserted into the slot, the top of the wire harness connector is provided with a housing, and the two sides of the wire harness connector are provided with positioning parts that match the positioning slot. The positioning parts are provided with limiting holes that match the locking rod.

[0011] As described above, the locking rod extends to one end of the outer cylinder, passing through the protective cover and the connector in sequence, and extending into the slot.

[0012] As described above, the housing contains an electronic wire harness body that is connected to the wire harness connector, and the electronic wire harness body extends to the outside of the housing.

[0013] Compared with existing technologies, this convenient plug-in electronic wire harness has the following advantages:

[0014] I. This utility model is equipped with a manually unlockable locking mechanism. By pressing the sleeve to drive the guide block to move, the moving part is pushed to move, thereby realizing the switching between the locking and unlocking states of the locking rod. It does not require forceful pulling of the wire harness connector, thus solving the problem that forceful pulling can easily cause irreversible damage to the wire harness connector.

[0015] Second, this utility model has a protective cover on the outside of the locking mechanism. The protective cover protects the locking mechanism and reduces the chance of the locking mechanism being accidentally touched. At the same time, one end of the protective cover is open, which makes it easy to manually operate the locking mechanism and is convenient to use.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0023] 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.

[0024] like Figure 1-5As shown, this utility model provides a technical solution: an easy-to-plug electronic wire harness, including a connector 1, with locking mechanisms 2 symmetrically arranged at both ends of the connector 1. The locking mechanism 2 includes an outer cylinder 21, an inner cylinder 22, a sleeve 23, a locking rod 24, a moving part 25, and a spring 26. The inner cylinder 22 is located at the middle of the bottom of the outer cylinder 21. The outer cylinder 21 and the inner cylinder 22 are integrally formed. The sleeve 23 is inserted into the outer cylinder 21 from the top and is located above the inner cylinder 22. The locking rod 24 passes through the bottom of the inner cylinder 22 and the outer cylinder 21 in sequence. The outer wall of the locking rod 24 is clearance-fitted with the inner wall surface of the inner cylinder 22. The moving part 25 passes through the locking rod 24 and the inner cylinder 22 in sequence and extends to the outside of the inner cylinder 22. A limiting piece 27 is connected to the top of the locking rod 24. The spring 26 is connected between the limiting piece 27 and the inner top wall of the sleeve 23.

[0025] like Figure 4 As shown, guide blocks 28 are symmetrically arranged on the inner wall of one end of the sleeve 23 embedded in the outer cylinder 21. Each of the two guide blocks 28 has an upwardly inclined guide slope on one side. Both ends of the moving part 25 are slidably engaged with the guide slope. Both guide blocks 28 are right-angled trapezoidal structures, and one of the guide blocks 28 is an inverted right-angled trapezoidal structure. The sliding engagement between the inclined surface of the guide block 28 and the moving part 25 drives the locking rod 24 to move, thereby realizing the switching between locking and unlocking states.

[0026] like Figure 2 As shown, a protective cover 3 is fitted over the locking mechanism 2. The length of the protective cover 3 is greater than the total length of the locking mechanism 2, making it less likely for the locking mechanism 2 to be accidentally touched. The protective cover 3 is a hollow structure with one end open, and the end of the protective cover 3 away from the opening is connected to the connector 1. The protective cover 3 protects the locking mechanism 2 and reduces the chance of the locking mechanism 2 being accidentally touched.

[0027] The connector 1 has a slot 4 on its top, and positioning grooves 5 are symmetrically provided on both sides of the top of the connector 1 near the slot 4. Metal contacts are provided at the bottom of the slot 4 and the top of the wire harness connector 6 to facilitate the transmission of power and signals. The positioning grooves 5 facilitate the alignment and insertion of the wire harness connector 6, thereby enabling easy plugging and unplugging.

[0028] like Figure 3 As shown, the locking rod 24 extends to one end of the outer cylinder 21, passing through the protective cover 3 and the connector 1 in sequence, and extends into the slot 4. A wire harness connector 6 is inserted inside the slot 4. The top of the wire harness connector 6 is provided with a housing 7, and the two sides of the wire harness connector 6 are provided with positioning parts 8 that match the positioning groove 5. The positioning parts 8 are provided with limiting holes that match the locking rod 24. When the bottom of the positioning part 8 abuts against the bottom end of the positioning groove 5, the position of the limiting hole corresponds exactly to the locking rod 24, so that the locking rod 24 can be inserted into the limiting hole for locking.

[0029] like Figure 1 , 3 As shown, the housing 7 has an electronic wire harness body 9 that is connected to the wire harness connector 6 inside, and the electronic wire harness body 9 extends to the outside of the housing 7.

[0030] Working principle: When in use, hold connector 1 with one hand and press the sleeves 23 on both sides of connector 1 with your fingers. The sleeves 23 move and compress the spring 26. At the same time, the sleeves 23 drive the guide block 28 to move laterally. The guide block 28 pushes the moving part 25 to move longitudinally. The longitudinal movement of the moving part 25 drives the locking rod 24 to move in the direction of compressing the spring 26, so that the locking rod 24 moves out of the slot 4. Then, take the outer shell 7 with the other hand, align the wire harness connector 6 with the slot 4, and insert the positioning part 8 into the positioning groove 5. When the bottom of the positioning part 8 abuts against the bottom of the positioning groove 5, release the sleeve 23. The locking rod 24 will automatically insert into the limiting hole on the positioning part 8 under the elastic force of the spring 26, thereby locking connector 1 and wire harness connector 6. After connection, power and signal are transmitted through the metal contacts at the bottom of the slot 4 and the top of the wire harness connector 6. When disconnection is required, repeat the above pressing operation to separate connector 1 and wire harness connector 6, which is convenient to use.

[0031] 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.
