Detailed ways

In order to make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

When faced with multi-channel cable communication transmission, it is necessary to select and use multi-channel cables adaptively. Taking two-way cable communication transmission as an example, when a front camera or rear camera on a car needs two different cameras to When providing video sources at the same time, or, in thermal imaging scenarios, when dual spectral channels of infrared detectors and visible light detectors are required, or when signal transmission and serial data transmission of other similar instruments and meters, two channels of data are required. communication transmission. Considering the simplicity of wiring and the miniaturization of the volume, it is necessary to provide an all-in-one, such as a two-in-one cable.

The two-in-one cable provided by the related art includes: an outer sheath, and a first cable and a second cable which are located inside the outer sheath and are insulated from each other. Wherein, the two ends of the first cable and the two ends of the second cable are respectively connected with electrical connectors of the same type.

Since the electrical connectors connected to both ends of the first cable and the second cable are of the same type, for example, both are male SMA connectors or both are female SMA connectors, on the one hand, it is inconvenient to distinguish the first cable On the other hand, it is inconvenient to distinguish which of the two ends of the same cable is the source end and which is the terminal, which makes the connection error of the two-in-one cable easily caused when connecting with external electrical devices. .

The embodiment of the present application provides a cable arrangement structure, as shown in FIG. 1 and FIG. 2 , the cable arrangement structure includes: multiple cables 1 and multiple electrical connectors 4 . Both ends are respectively connected with an electrical connector 4 . The electrical connector 4 has a foolproof structure 401 , and the foolproof structure 401 is configured to be able to distinguish any one of the cables 1 from the multi-channel cables 1 , as well as to the electrical connectors 4 at both ends of any one of the cables 1 . distinguish.

When the cable arrangement structure provided in the embodiment of the present application is applied, the first connection section 12 of each cable 1 is connected to the corresponding electrical connector 4 on the first electrical device M1 through the electrical connector 4 thereon. , so that the second connecting segment 13 of each cable 1 is connected to the corresponding electrical connector 4 on the second electrical device M2 through the electrical connector 4 thereon. The electrical connector 4 on the first electrical device M1 and the electrical connector 4 on the second electrical device M2 can be adapted and connected to the electrical connector 4 involved in the embodiments of the present application.

In the cable arrangement structure provided by the embodiment of the present application, by making the electrical connector 4 have a foolproof structure 401, the electrical connector 4 at both ends of any cable 1 can be distinguished by using the foolproof structure 401, which can easily determine The source and terminal of any cable 1, and at the same time, the foolproof structure 401 can also be used to distinguish any cable 1 from the multi-channel cable 1, so as to avoid mistakes when connecting with external electrical devices, and ensure effective connect.

For the above-mentioned multi-channel cables 1, they can be independent and used in combination only when used in combination. In addition, when used in combination, they can be combined using external connectors, for example, the external connectors can be ropes or snap rings, etc. .

Alternatively, the multi-channel cable 1 can also be designed as a whole. The following is an exemplary description of the integrated multi-channel cable 1:

As shown in FIG. 2 , the cable arrangement structure further includes: an outer sheath 2 , a first tap 31 , and a second tap 32 .

The cable 1 includes: a main body section 11 , a first connection section 12 and a second connection section 13 located at both ends of the main body section 11 , the main body section 11 of the multi-channel cable 1 is located in the outer sheath 2 , The first connection section 12 is branched through the first tap 31 , and the second connection section 13 of the multi-channel cable 1 is branched through the second tap 32 .

The multi-channel cable 1 corresponds to a plurality of first connection segments 12 , and the plurality of first connection segments 12 are branched through the first taps 31 , that is, separated from each other. Likewise, the multi-channel cable 1 also corresponds to a plurality of second connection sections 13 , and the plurality of second connection sections 13 achieve the purpose of separation through the second taps 32 .

The first connection section 12 and the second connection section 13 of each cable 1 are respectively connected with one electrical connector 4; In the cable 1, any one of the cables 1 is distinguished, and the electrical connectors 4 at both ends of any one of the cables 1 are distinguished.

The application state of the cable arrangement structure provided by the embodiment of the present application is described with reference to FIG. 7 , so that the first connection section 12 of each cable 1 is connected to the corresponding electrical connector 4 on the first electrical device M1 through the electrical connector 4 thereon. The electrical connectors 4 are connected, so that the second connecting section 13 of each cable 1 is connected to the corresponding electrical connectors 4 on the second electrical device M2 through the electrical connectors 4 thereon. The electrical connector 4 on the first electrical device M1 and the electrical connector 4 on the second electrical device M2 can be adapted to be connected with the electrical connector 4 involved in the embodiments of the present application.

In the cable arrangement structure provided in the embodiment of the present application, the multiple main body segments 11 of the multi-channel cable 1 share one outer sheath 2, so as to simplify the cable arrangement structure and reduce the integrated volume of the cable 1; The plurality of first connection sections 12 and the plurality of second connection sections 13 of the cable 1 are branched through the first tap 31 and the second tap 32 respectively, so as to be connected with the corresponding external electrical devices. By making the electrical connector 4 have the foolproof structure 401, the electrical connector 4 at both ends of any cable 1 can be distinguished by the foolproof structure 401, so that the source end and the terminal of any cable 1 can be easily determined, At the same time, the fool-proof structure 401 can also be used to distinguish any one of the cables 1 from the multi-channel cables 1, so as to avoid mistakes in connection with external electrical devices and ensure effective connection.

In some possible implementations, the foolproof structure 401 on the electrical connector 4 is at least one of different connection structures and different appearance structures. That is to say, the foolproof structure 401 may be the connection structure of the electrical connector 4 , the external appearance structure of the electrical connector 4 , or a combination of the two.

The connection structure refers to a structure used to realize the connection between two electrical connectors 4 to be electrically connected, and the connection between the electrical connectors 4 involved here may be a mechanical connection or an electrical connection. It can also be a connection relationship that achieves the purpose of electrical connection and mechanical connection at the same time. By using different connection structures as the foolproof structure 401 , on the premise of realizing foolproofness, it is also beneficial to simplify the structure of the electrical connector 4 .

The appearance structure refers to the structure used to identify the electrical connector 4. By using different appearance structures as the foolproof structure 401, it is beneficial to pair more cables 1, such as three or more cables. 1 for effective identification.

The following is an exemplary description of some possible implementations of the above-mentioned connection structure and appearance structure:

When using different connection structures on the two electrical connectors 4 to be electrically connected as the foolproof structure 401 , for example, the connection structures may include the male head 41 of the electrical connector 4 and the female head 42 of the electrical connector 4 . ; Among them, the male head 41 of the electrical connector 4 and the female head 42 of the electrical connector 4 can be adapted to be electrically plugged.

The male head 41 of the electrical connector 4 refers to an electrical connector joint with pins inside, and the female head 42 of the electrical connector 4 refers to an electrical connector joint with a socket that matches the pins inside. It can realize electrical communication between the two electrical connectors 4 by adapting and plugging.

Since the internal structures of the male head 41 of the electrical connector 4 and the female head 42 of the electrical connector 4 are different, the two are easy to identify and distinguish, and can be used as the foolproof structure 401 .

For each cable 1 , the electrical connectors 4 connected at both ends can be male 41 or female 42 , or one of them can be male 41 and the other can be female 42 . For example, in the embodiment of the present application, for the first connection section 12 and the second connection section 13 of each cable 1, one of the connected electrical connectors 4 adopts the male head 41, and the other connected electrical connector 4 adopts the male head 41. The female header 42 is arranged in this way, which is beneficial to distinguish the source end and the terminal end of any cable 1 , and ensures the correct identification of the terminal end and the source end of the cable 1 .

For the effective distinction of two or more cables 1 , at least two different types of foolproof structures 401 are required to be realized. On the premise that the male head 41 of the electrical connector 4 and the female head 42 of the electrical connector 4 are used as one type of foolproof structure 401, the following is an exemplary description of another type of foolproof structure 401:

In some possible implementations, the connection structure includes: a first connection structure 43 and a second connection structure 44 respectively disposed on the two electrical connectors 4 to be electrically plugged; the first connection structure 43 and the second connection structure 44 The connection structure 44 is used for making the two electrical connectors 4 electrically plugged with each other to be mechanically connected at the same time.

Wherein, the “two electrical connectors 4 electrically plugged with each other” involved in this implementation manner may be two electrical connectors 4 electrically plugged by means of the male head 41 and the female head 42 .

The first connection structure 43 and the second connection structure 44 enable the two electrical connectors 4 to be mechanically connected in a suitable manner, which can constitute another foolproof structure 401. In this way, the male head 41 of the electrical connector 4, the electrical connector 4 The combination of the female head 42 , the first connection structure 43 and the second connection structure 44 can effectively distinguish two or more cables 1 .

As mentioned above, the first connection structure 43 and the second connection structure 44 can be used in combination with the male head 41 and the female head 42 to achieve the purpose of foolproofing the multi-channel cable 1 .

In some implementations, only the combination of the first connection structure 43 and the second connection structure 44 can be used for foolproof purpose, and the first connection structure 43 and the second connection structure 44 can be different from the above-mentioned male head 41 With the female head 42, the first connection structure 43 and the second connection structure 44 can only realize the mechanical connection between the two electrically conductive electrical connectors 4, so as to achieve the purpose of mutual fixation.

In some examples, for each cable 1 , the electrical connector 4 at one end may have a first connection structure 43 , and the electrical connector 4 at the other end may have a second connection structure 44 .

The two cables 1 can also be effectively identified by the first connection structure 43 and the second connection structure 44 .

For example, the geometrical dimensions of the first connection structures 43 on at least some of the multi-channel cables 1 can be made different; correspondingly, the geometrical dimensions of the second connection structures 44 on at least some of the multi-channel cables 1 are different.

For example, for two cables 1, the two electrical connectors 4 at both ends of any one cable 1 can have a first connection structure 43 and a second connection structure 44 respectively, and for these two cables 1, The two electrical connectors 4 connected to the two first connection segments 12 respectively adopt different first connection structures 43 and second connection structures 44 , correspondingly, the two electrical connectors connected to the two second connection segments 13 4. Different second connection structures 44 and first connection structures 43 are respectively adopted. At the same time, for one cable 1, the first connection structure 43 and the second connection structure 44 on the two electrical connectors 4 at both ends have the first geometric size, and for the other cable 1, the two ends of the cable 1 are The first connection structure 43 and the second connection structure 44 on the two electrical connectors 4 have a second geometric size, and the first geometric size is different from the second geometric size, so that the first connection structure 43, the second connection structure 44 and the By combining the different sizes of the two, the foolproof design of the two-way cable 1 can be completed.

For some possible shapes of the first connection structure 43 and the second connection structure 44 mentioned above, an exemplary description is given below:

In some possible implementations, one of the first connection structure 43 and the second connection structure 44 is an internal thread, and the other is an external thread, the internal thread and the external thread are matched, and the two can be connected by thread.

When one of the first connection structure 43 and the second connection structure 44 is an internal thread and the other is an external thread, the different geometric dimensions of the first connection structure 43 and the second connection structure 44 include but are not limited to: different threads Diameters, different pitches, etc.

For example, the electrical connector 4 involved in the embodiment of the present application is an SMA connector, the first connection structure 43 is an internal thread located on the inner wall of the electrical connector 4 , and the second connection structure 44 is located on the outer wall of the electrical connector 4 . In this way, the electrical connector 4 provided by the embodiment of the present application may include the following types:

As shown in FIG. 3 , the connection structure on the electrical connector 4 includes: a male head 41 and a first connection structure 43 , wherein the first connection structure 43 is an internal thread. Both of the above two types of connection structures can be used as the foolproof structure 401 .

As shown in FIG. 4 , the connection structure on the electrical connector 4 includes: a female head 42 and a second connection structure 44 , wherein the second connection structure 44 is an external thread.

The electrical connector 4 shown in FIG. 3 and the electrical connector 4 shown in FIG. 4 can be adapted for connection, which includes: the electrical plug connection between the male header 41 and the female header 42 , and the first connection Mechanical connection between structure 43 and second connecting structure 44 .

As shown in FIG. 5 , the connection structure on the electrical connector 4 includes: a male head 41 and a second connection structure 44 , wherein the second connection structure 44 is an external thread.

As shown in FIG. 6 , the connection structure on the electrical connector 4 includes: a female head 42 and a first connection structure 43 , wherein the first connection structure 43 is an internal thread.

The electrical connector 4 shown in FIG. 5 and the electrical connector 4 shown in FIG. 6 can be adapted for connection, which includes: the electrical plug connection between the male header 41 and the female header 42, and the first connection Mechanical connection between structure 43 and second connecting structure 44 .

Based on the above foolproof design, in conjunction with FIG. 2 , the following is an exemplary description of how to accurately distinguish the two cables 1:

In some possible implementations, as shown in FIG. 2 , the foolproof structure 401 on the electrical connector 4 for connecting the first connection section 12 of the first cable 1 includes: a female head 42 and a first A connection structure 43, the foolproof structure 401 on the electrical connector 4 for connecting the second connection section 13 of the first cable 1 includes: a male head 41 and a second connection structure 44 in the form of external threads.

The foolproof structure 401 on the electrical connector 4 for connecting the first connection section 12 of the second cable 1 includes: a male head 41 and a first connection structure 43 in the form of an internal thread, so that the second connection of the second cable 1 The foolproof structure 401 on the electrical connector 4 connected by the segment 13 includes: a female head 42 and a second connection structure 44 in the form of an external thread.

For the above four electrical connectors 4, they can be connected to different electrical components or connected to different electrical connectors on the electrical components. According to the structure of each electrical connector 4 in the cable arrangement structure, it can be adaptively designed to carry out It is sufficient to adapt the structure of the connected electrical connector.

For example, for the electrical connector 4 connected to the first connection section 12 in the cable arrangement structure, if its foolproof structure 401 includes: a female head 42 and a first connection structure 43 in the form of an internal thread, correspondingly, make it suitable for The foolproof structure of the electrical connector on the first electrical device M1 to be connected includes: a second connection structure in the form of a male head and an external thread.

For the electrical connector 4 connected to the first connection section 12 in the cable arrangement structure, if its foolproof structure 401 includes: a male head 41 and a first connection structure 43 in the form of an internal thread, correspondingly, make it suitable for connection The foolproof structure of the electrical connector on the first electrical device M1 includes: a female head and a second connection structure in the form of an external thread.

For the electrical connector 4 connected to the second connection section 13 in the cable arrangement structure, if its foolproof structure 401 includes: a female head 42 and a second connection structure 44 in the form of an external thread, correspondingly, make it suitable for connection The foolproof structure of the electrical connector on the second electrical device M2 includes: a first connection structure in the form of a male head and an internal thread.

For the electrical connector 4 connected by the second connection section 13 in the cable arrangement structure, if its foolproof structure 401 includes: a male head 41 and a second connection structure 44 in the form of an external thread, correspondingly, make it suitable for connection The foolproof structure of the electrical connector on the second electrical device M2 includes: a first connection structure in the form of a female head and an internal thread.

It can be seen that the above-mentioned four electrical connectors 4 connected to the ends of the first cable 1 and the second cable 1 are different from each other. In actual use, the first electrical device M1 and the second electrical device M2 can only be connected with The corresponding ends of the corresponding cables 1 are connected, that is to say, each electrical connector 4 can only correspond to the only one electrical connector on the first electrical device M1 and the second electrical device M2. There will be a misconnection, and the user will be guided correctly.

It can be seen that the above-mentioned arrangement of the cables 1 provided in the embodiments of the present application can not only combine the two coaxial cables 1 into one, which is beneficial to the simplified design of the product and the optimization of the appearance of the product, but also enables the 1 and the two ends of each cable 1 are accurately distinguished, which is convenient for user operation and improves user experience.

In addition, the cable arrangement structure provided in the embodiment of the present application can also be used to obtain a cable 1 with a longer length. In application, the electrical connector 4 of one cable arrangement structure can be connected with the electrical connectors of other cable arrangement structures. 4 Perform an adaptive connection, so that a combined cable with a length of 2 times or more than the original cable length can be obtained. cable.

The above example illustrates that one of the first connection structure 43 and the second connection structure 44 is an internal thread and the other is an external thread. The first connection structure 43 and the second connection structure 44 can also be designed as other possible structures. Shape, for example, one of the first connection structure 43 and the second connection structure 44 is a clamping block, the other is a clamping slot, the clamping block and the clamping slot are adapted, and the two can be clamped.

When one of the first connection structure 43 and the second connection structure 44 is a card block and the other is a card slot, the different geometric dimensions of the first connection structure 43 and the second connection structure 44 include but are not limited to: different cards Block or slot widths, different depths of blocks or slots, etc.

The working principle of the clamping block and the clamping groove as the foolproof structure 401 is similar to that of the internal thread and the external thread as the foolproof structure 401 , and details are not repeated here.

When the first foolproof structure 401 formed by the male head 41 of the electrical connector 4 and the female head 42 of the electrical connector 4 and the second foolproof structure 401 formed by the first connection structure 43 and the second connection structure 44 are simultaneously When existing, the above-mentioned arrangement of cables 1 provided in the embodiments of the present application is not only applicable to the integration and differentiation of two cables 1 , but also to the integration and differentiation of more than two cables 1 .

Taking the fool-proof identification of the three-way cable 1 as an example, one of the cables 1 can be provided with an infrared detector spectral channel, and the other two cables 1 can be provided with a visible light detector spectral channel. The electrical connectors 4 arranged on the cables 1 with the same function are the same, that is, they are identical two-way. In this way, based on the above-mentioned arrangement of the cables 1, the purpose of effectively distinguishing the multi-channel cables 1 can be achieved.

When used to distinguish three or more cables 1 with different functions, the first foolproof structure 401 composed of the electrical connector male head 41 and the electrical connector female head 42 can be used in combination, and The second foolproof structure 401 is formed by the first connection structure 43 and the second connection structure 44 .

Further, the electrical connector 4 can also have a third foolproof structure 401 to be combined with the above two foolproof structures 401. In some possible implementations, the foolproof structure 401 is an appearance structure. The structure is an identification mark disposed on the surface of the electrical connector 4 , that is, the electrical connector 4 has an identification mark, and the identification mark constitutes a foolproof structure 401 .

For example, the identification mark is at least one of a color mark and a pattern mark, for example, the electrical connectors 4 at different ends of the cable 1 can be provided with different color coatings, for example, red, blue, green, yellow, white etc., the electrical connectors 4 at different ends of the cable 1 can also be provided with different pattern marks, as shown in FIG. 7 , for example, the pattern marks include a first pattern mark 45 , such as the letter E to indicate a terminal, and also include a second pattern mark 45 . The pattern mark 46 is, for example, the letter S for the source end or the like.

When the identification mark is used as the foolproof structure 401, it can be matched with the first foolproof structure 401 formed by the male head 41 of the electrical connector 4 and the female head 42 of the electrical connector 4, as well as the first connection structure 43 and the second connection structure 44. The second foolproof structure 401 is used together, which is beneficial to simplify the manufacturing process of the electrical connector.
