Technical Field

[0001] The utility model relates to the technical field of adapter components, in particular to a terminal harness adapter component. Background Art

[0002] A terminal harness adapter is a device used to connect different harnesses or cables. It usually contains multiple terminals for inserting and fixing wires and connecting them to another harness or device. The main function of the adapter is to achieve electrical connection between wires while ensuring the stability and reliability of the connection.

[0003] The authorization announcement number in the prior art is: CN206432412U, and the name is a terminal wiring harness adapter assembly. This design solves the problem that the original terminal wiring harness adapter assembly has no auxiliary installation device, which makes the installation time-consuming and labor-intensive, and the installation quality is difficult to ensure. The auxiliary installation mechanism can be quickly opened. The utility model saves time and effort in installation, is easy to operate, has good stability and high reliability.

[0004] However, in actual use, it was found that when the device is not connected to the terminal harness, its interface will be exposed to the air for a long time, which will cause dust to enter the interface, which may affect the transfer effect of the device. Utility Model Content

[0005] The technical problem solved by the utility model is to prevent an interface from being exposed to the air for a long time when not in use, and to provide a terminal harness adapter component.

[0006] In order to solve the above-mentioned technical problems, the utility model provides a terminal wiring harness adapter assembly, including an adapter seat body, a dustproof mechanism and a positioning mechanism. The dustproof mechanism includes reserved grooves opened on both sides of the adapter seat body, and dustproof plates that can slide in the reserved grooves. The outer surfaces of the two dustproof plates are provided with limiting holes, and slidable limiting rods are installed in the supports on both sides of the upper surface of the adapter seat body. The outer surfaces of the two limiting rods are fixedly connected with discs, and the outer surface of each of the discs is fixedly connected with a telescopic spring.

[0007] The positioning mechanism comprises two threaded rods threadedly connected to the two sides of the adapter body, and a positioning block rotatably connected to one end of the threaded rod.

[0008] Preferably, the diameter value of the limit rod is consistent with the diameter value of the limit hole, and the limit rod and the limit hole are located on the same axis. By limiting the relationship between the limit rod and the limit hole, the position of the dustproof plate can be conveniently limited by the limit rod, which is convenient to use.

[0009] Preferably, the two discs are respectively sleeved on the outside of the two limit rods, and the sides of the two discs that are away from each other are respectively fixedly connected to the outer surfaces of the supports on both sides of the upper surface of the adapter body. The state of the limit rod can be limited by limiting the positional relationship of the discs, which makes it convenient to stably insert the limit rod into the limit hole to limit the dustproof plate.

[0010] Preferably, a handle is fixedly connected to the outer surface of each of the discs, and a groove is provided on the upper surface of each of the dustproof plates. By providing a handle, the contact area of ​​the disc can be increased to facilitate pulling the disc, and by providing a groove, the dustproof plate can be pulled conveniently, thereby facilitating the installation of the terminal harness on the device for transfer.

[0011] Preferably, the inner walls of the two reserved grooves are provided with two receiving grooves, and the size of the positioning block is consistent with the size of the receiving groove. By setting the receiving groove, the positioning block can be received into the disc, thereby facilitating the movement of the dustproof plate in the reserved groove, which is beneficial to the dustproof work.

[0012] Preferably, the outer surface of each positioning block is fixedly connected to two guide rods, and the outer surfaces of the eight guide rods are respectively slidably mounted on both sides of the adapter body. By setting the guide rods, the movement state of the positioning block can be limited, so that the positioning block will move linearly when the threaded rod rotates.

[0013] Preferably, a wire is installed on the upper surface of the adapter body, and a first connector and a second connector are installed on the inner walls of the two reserved slots respectively. By arranging the wire, the first connector and the second connector to cooperate with each other, the device can perform the work of connecting terminal harnesses of different sizes.

[0014] Preferably, a vent is provided on the upper surface of the adapter body, and pillars are fixedly connected to the four corners of the bottom surface of the adapter body. The vent can ensure the circulation of air inside and outside the device to avoid overheating. The pillar can make the device more stably placed on the contact surface, and at the same time reduce the wear rate of the bottom surface of the adapter body and increase the service life of the device.

[0015] Compared with the related art, the utility model has the following beneficial effects:

[0016] 1. The utility model sets a dustproof mechanism and a positioning mechanism to cooperate with each other. On the one hand, when not in use, the first connector and the second connector can be respectively protected from dust by two dustproof plates to prevent a large amount of dust from entering the first connector and the second connector and affecting the switching effect of the device. On the other hand, when in use, the stability of the terminal harness installed on the first connector and the second connector can be improved. By rotating the corresponding two threaded rods, the two corresponding positioning blocks can clamp the connection between the terminal harness and the device to reduce the probability of loosening.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 A terminal harness adapter assembly includes an adapter body 1, a dustproof mechanism 2 and a positioning mechanism 3. The dustproof mechanism 2 includes reserved grooves 201 opened on both sides of the adapter body 1, and a dustproof plate 202 that can slide in the reserved grooves 201.

[0029] The adapter body 1 is an existing mechanism and is the main part of the adapter assembly, which is used to accommodate and fix the terminals. The adapter body 1 is usually made of plastic, metal or other durable materials to provide sufficient strength and durability.

[0030] A wire 4 is installed on the upper surface of the adapter body 1, and a first connector 5 and a second connector 6 are installed on the inner walls of the two reserved slots 201 respectively. By arranging the wire 4, the first connector 5 and the second connector 6 to cooperate with each other, the device can perform the work of connecting terminal harnesses of different sizes.

[0031] like Figure 4 As shown, the shapes of the first connector 5 and the second connector 6 are only for reference, and their models are not limited too much.

[0032] The first connector 5 and the second connector 6 are key parts of the terminal harness, and are usually made of conductive materials, such as copper or copper alloy. Each terminal has an insertion hole for receiving the exposed part of the wire and ensuring good contact between the wire and the terminal in a certain way.

[0033] A vent 7 is provided on the upper surface of the adapter body 1 , and pillars 8 are fixedly connected to the four corners of the bottom surface of the adapter body 1 .

[0034] The vents 7 can ensure the circulation of air inside and outside the device to avoid overheating, and the support 8 can make the device more stably placed on the contact surface, while the wear rate of the bottom surface of the adapter body 1 can be reduced, thereby increasing the service life of the device.

[0035] The outer surfaces of the two dustproof plates 202 are provided with limiting holes 207. The limiting holes 207 can facilitate the subsequent limitation of the position of the dustproof plates 202, thereby facilitating the dustproof work on the inside of the first joint 5 and the second joint 6, and preventing the first joint 5 and the second joint 6 from being exposed to the air for a long time and causing dust to enter the first joint 5 and the second joint 6.

[0036] Slidable limit rods 203 are installed in the supports on both sides of the upper surface of the adapter body 1. The outer surfaces of the two limit rods 203 are fixedly connected with discs 204. The outer surface of each disc 204 is fixedly connected with a telescopic spring 205.

[0037] The diameter value of the limiting rod 203 is consistent with the diameter value of the limiting hole 207. The limiting rod 203 and the limiting hole 207 are located on the same axis. By limiting the relationship between the limiting rod 203 and the limiting hole 207, the position of the dustproof plate 202 can be conveniently limited by the limiting rod 203, which is convenient to use.

[0038] The two discs 204 are respectively sleeved on the outside of the two limiting rods 203 , and the sides of the two discs 204 that are away from each other are respectively fixedly connected to the outer surfaces of the supports on both sides of the upper surface of the adapter body 1 .

[0039] The state of the limiting rod 203 can be limited by limiting the position relationship of the disc 204 , so that the limiting rod 203 can be stably inserted into the limiting hole 207 to limit the dustproof plate 202 .

[0040] like Figure 1 As shown, this is the state when the device is not connected to the terminal harness. The two dustproof plates 202 can respectively block the outside of the first connector 5 and the second connector 6, which can effectively prevent a large amount of dust from entering the first connector 5 and the second connector 6 and affecting the switching effect of the device.

[0041] And the two dustproof plates 202 will not shake at will at this time, because the two limiting rods 203 are respectively inserted into the corresponding limiting holes 207 at this time, so that the movement trajectory of the dustproof plates 202 can be limited.

[0042] When the terminal harness needs to be installed in the first connector 5 or the second connector 6, the corresponding disc 204 can be pulled outward to move the corresponding limiting rod 203 out of the limiting hole 207. At this time, the telescopic spring 205 is in a stretched state, deformed and generates elastic force, so that the dustproof plate 202 can be pulled upward to expose the first connector 5 or the second connector 6 to the outside, and then the terminal harness can be installed in the first connector 5 or the second connector 6.

[0043] Preferably, the dustproof plate 202 can be completely pulled out from the reserved slot 201, or it can remain in the reserved slot 201. In this case, the bottom surface of the dustproof plate 202 can be in contact with the upper surface of the terminal harness. At the same time, the dustproof plate 202 can be properly limited with the help of the limiting rod 203 and the telescopic spring 205, and the dustproof plate 202 will not shake easily.

[0044] A handle 206 is fixedly connected to the outer surface of each disc 204 , and a groove 208 is formed on the upper surface of each dustproof plate 202 .

[0045] By providing the handle 206, the contact area of ​​the disc 204 can be increased to facilitate pulling the disc 204, and by providing the groove 208, the dustproof plate 202 can be easily pulled, which facilitates the installation of the terminal harness on the device for switching.

[0046] The positioning mechanism 3 includes two threaded rods 301 threadedly connected to two sides of the adapter body 1 , and a positioning block 302 rotatably connected to one end of the threaded rods 301 .

[0047] Two receiving grooves 304 are provided on the inner walls of the two reserved grooves 201. The size of the positioning block 302 is consistent with the size of the receiving groove 304. By setting the receiving groove 304, the positioning block 302 can be received into the disc 204, thereby facilitating the movement of the dustproof plate 202 in the reserved groove 201 and avoiding interference with the movement of the dustproof plate 202, which is beneficial to the dustproof work.

[0048] The outer surface of each positioning block 302 is fixedly connected to two guide rods 303, and the outer surfaces of the eight guide rods 303 are slidably mounted on both sides of the adapter body 1. By setting the guide rods 303, the movement state of the positioning block 302 can be limited, so that the positioning block 302 will move linearly when the threaded rod 301 rotates.

[0049] In summary, the device can provide dust-proof effect for the first connector 5 and the second connector 6. When the device is connected to the external terminal harness through the first connector 5 and the second connector 6, the connection can be reinforced by the provided positioning mechanism 3, thereby reducing the possibility of looseness when the terminal harness is connected to the device.

[0050] By rotating the two corresponding threaded rods 301, the two corresponding positioning blocks 302 can be moved toward or away from each other, so that the terminal harness installed on the first connector 5 or the second connector 6 can be auxiliary positioned to reduce the probability of looseness.

[0051] The specific implementation process of the utility model is as follows: when in use, the disc 204 can be pulled outward to draw the corresponding limiting rod 203 out of the corresponding limiting hole 207, thereby releasing the limiting work on the dustproof plate 202, and then the dustproof plate 202 can be pulled upward to expose the first connector 5 or the second connector 6 to the outside, so that the external terminal harness can be installed on the device, and the corresponding two threaded rods 301 can be rotated at the same time. When the two threaded rods 301 are rotated, the corresponding two positioning blocks 302 will be moved out of the corresponding storage grooves 304 respectively and move closer to each other, so that the terminal harness can be properly clamped and positioned by the two positioning blocks 302, which effectively reduces the problem of looseness at the interface and improves the practicality of the device. When not in use When the dustproof plate 202 is at the bottom, the two threaded rods 301 can be rotated to make the two positioning blocks 302 move to the corresponding storage grooves 304 for storage, and the disc 204 can be pulled outward at the same time, so that the dustproof plate 202 can slide downward in the reserved groove 201 with the help of its own gravity. When it slides to the bottom, the pulled disc 204 can be released, and the limiting rod 203 will be reset with the help of the elastic force generated by the deformation of the telescopic spring 205, so that the limiting rod 203 bounces into the corresponding limiting hole 207, thereby realizing the limiting work of the dustproof plate 202. In this way, the dustproof plate 202 can block the outside of the first joint 5 or the second joint 6, avoiding the first joint 5 or the second joint 6 from being exposed to the air for a long time, and preventing a large amount of dust from entering the first joint 5 or the second joint 6 and affecting the transfer effect of the device.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
