Description

Male connector and data cable

Technical Field

The present application relates to the technical field of data cables, and in particular to a male connector and a data cable.

Background technique

The male connector is a component of the data cable, which is used to plug into the female connector set on the terminal to achieve signal and/or electrical transmission. There are many types of male connectors. For example, as mobile phones continue to develop towards thinner and lighter, Apple has launched a smaller lightning male connector, also known as a "lightning" male connector.

The lightning male connector includes a male connector body made of insulating material, with 8 signal pins (PIN pins are a metal material used in connectors to conduct electricity (signals)) on the front and back sides respectively. The 8 signal pins on the front and the 8 signal pins on the back have the same function. It can work normally when the front or back side is inserted into the interface, so there is no need to distinguish the front and back sides when using it, which saves trouble and effort.

However, there are only 8 signal pins in the lightning male connector to transmit signals or electricity, and there are fewer lines for transmitting signals or electricity, which may limit the functions of the lightning male connector. For example, when the lightning male connector is used for charging, it cannot be used to transmit audio signals. The lightning male connector cannot be used as a transmission component for headphones and chargers at the same time.

Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

The male connector of the present application can be a Type-C male connector or a lightning male connector. The concept of the present application is described in detail below using the lightning male connector as an example.

The lightning male connector is used to be inserted into the female connector. The female connector can be set on a mobile terminal (such as a mobile phone, a tablet computer) or on other devices. The female connector for inserting the lightning male connector of this application is the same as the existing female connector, with 8 connection pins in the middle and 2 empty pins (short pins) at both ends.

As shown in Figure 1, the lightning male connector includes a male connector body 1 and a signal pin 2 and an auxiliary signal pin 3 arranged on the male connector body 1. The signal pin 2 overlaps with the connection pin of the female connector, and the auxiliary signal pin 3 overlaps with the empty pin of the female connector. By adding the auxiliary signal pin 3, the signal and/or electrical transmission line is increased, thereby improving the use occasions of the lightning male connector. For example, when the signal pin 2 is used for charging, the auxiliary signal pin 3 can be used to transmit audio signals, so that the lightning male connector can be used as an audio transmission device while charging.

The lightning male connector can be configured in a variety of ways, which are described in detail below using a specific embodiment as an example.

Embodiment 1

The signal pin 2 and the male connector body 1 can be the same as the existing ones to facilitate the setting and reduce the cost of the lightning male connector. The signal pin 2 is a generally long strip metal terminal 21, and the male connector body 1 is an injection molded body, through which the metal terminal 21 is fixed.

The arrangement of the metal terminals 21 is the same as the existing ones. There are 16 metal terminals 21 in the male plug body 1. The 16 metal terminals 21 are arranged in two layers, forming 8 signal pins 2 located on the front side of the male plug body 1 and 8 signal pins 2 located on the back side of the male plug body 1, so that the lightning male plug does not need to distinguish between the front and back sides when in use. The rear end of the metal terminal 21 is located at the rear end of the male plug body 1, extending out of the male plug body 1, and is used to connect with the transmission line of the data line to realize signal or electricity transmission. Of course, the number of signal pins set on the front or back side of the male plug body 1 may not be 8.

The outer side of the male body 1 is provided with a metal shell 31, and the metal shell 31 is used as an auxiliary signal pin 3. The front end of the metal shell 31 extends to the front end of the male body 1, and is used to overlap with the empty pin of the female connector. The rear end of the metal shell 31 is provided with a connecting terminal 33, which is connected to the transmission line through the connecting terminal 33 to realize signal or electrical transmission.

The metal shell 31 can be processed by an existing mold, and the processed metal shell 31 is the same as the existing metal shell 31. A metal ring 32 is sleeved on the rear end of the metal shell 31, and a connecting terminal 33 is arranged on the metal ring 32. By setting in the above manner, it can be processed on the basis of the existing lightning male connector, which is low in cost, convenient in processing, and saves trouble and labor.

As shown in Figures 2 and 3, a connecting terminal 33 is respectively set at the opposite ends of the metal ring 32. When the metal ring 32 is sleeved on the male head body 1, the two connecting terminals 33 are respectively located on both sides of the male head body 1, and can be located in the middle of the side for easy setting. When the front side of the lightning male head is inserted into the female head connector, signal or electricity transmission can be achieved through the two connecting terminals 33 and the metal shell 31. When the back side of the lightning male head is inserted into the female head connector, signal or electricity transmission is also achieved through the two connecting terminals 33 and the metal shell 31. With such a setting, the structure is simple, and fewer connecting terminals 33 are set, so that at most two transmission lines are added, and the number of additional transmission lines is small.

As mentioned above, the male body 1 and the metal shell 31 can be processed by existing methods. The male body 1 processed by the existing technology is provided with grooves on both sides, and the metal shell 31 is roughly the same shape as the male body 1. The metal shell 31 is also provided with grooves 311 corresponding to the grooves of the male body 1 on both sides (as shown in Figure 4). In the prior art, a lug is provided in the shell of the female connector, and a grounding wire connected to the shell is provided outside the shell. When the lightning male connector is inserted into the female connector, the lug is stuck in the groove of the metal shell 31, and the empty pin is overlapped on the metal shell 31. The lightning male connector is grounded through the lug, metal shell 31, empty pin and grounding wire to prevent static electricity.

In the present application, the metal shell 31 can be insulated from the female connector in order to realize that the metal shell 31 can be used as the auxiliary signal pin 3. In the present application, the metal shell 31 can be insulated from the female connector in a variety of ways.

In the first example, after the metal shell 31 is processed, the groove 311 of the metal shell 31 is hollowed out. When the metal shell 31 is installed on the male connector body 1, the insulated male connector body 1 is exposed. When the lightning male connector is inserted into the female connector, the ear of the female connector contacts the male connector body 1 to achieve insulation between the metal shell 31 and the female connector. With this arrangement, the metal shell 31 is slightly modified, and the female connector can use the existing female connector, which has a simple structure, is easy to process, and has a low cost.

In the second example, after the metal shell 31 is processed, an insulating layer (paint or plastic) is provided in the groove 311 of the metal shell 31. When the lightning male connector is inserted into the female connector, the ear of the female connector contacts the insulating layer of the metal shell 31, thereby achieving insulation between the metal shell 31 and the female connector. With such a configuration, the metal shell 31 is slightly modified, and the female connector can use an existing female connector, which has a simple structure, is easy to process, and has a low cost.

In the third example, an insulating layer may be provided on the ear of the female connector. When the lightning male connector is inserted into the female connector, the insulating layer of the ear is used to insulate the metal shell 31 from the female connector.

In the fourth example, the metal shell 31 and the ear are the same as the existing ones, and no changes are made, but no grounding wire is provided on the female connector. In this way, the metal shell 31 can also be used as the auxiliary signal pin 3.

Embodiment 2

As shown in FIG5 , the male connector body 1 is still an injection molded body, the male connector body 1 is wrapped with a circuit board 4, and the signal pin 2 is soldered on the circuit board 4. The circuit board 4 and the male connector body 1 are arranged in the same manner as in the prior art, and both sides of the circuit board 4 are provided with signal pins 2, and the arrangement of the signal pins 2 is also the same as in the prior art, so as to reduce the processing cost of the lightning male connector.

The signal pin 2 is a thin sheet welded on the circuit board 4. Eight signal pins 2 are arranged on both sides of the circuit board 4. The signal pin 2 is set at the front end of the circuit board 4. The male plug body 1 is exposed at the rear end of the circuit board 4. The transmission line of the data line is welded to the circuit board 4, and the conduction between the signal pin 2 and the transmission line is achieved through the circuit board 4.

The auxiliary signal pin 3 is also a thin sheet welded on the circuit board 4. The signal pin 2 is arranged in the middle of the front end of the circuit board 4, and the auxiliary signal pin 3 is arranged on both sides of the front end of the circuit board 4. The auxiliary signal pin 3 includes a first part 34 and a second part 35 connected to each other (as shown in Figure 6). The first part 34 is located at the front end of the signal pin 2 and extends along the arrangement direction of the signal pin 2. The second part 35 is located at the side end of the signal pin 2, and the extension direction is the same as the extension direction of the signal pin 2. Such a configuration facilitates the conduction of the auxiliary signal pin 3 and the transmission line through the circuit board 4, and facilitates the overlap of the auxiliary signal pin 3 with the empty pin of the female connector.

Two mounting positions are provided on each surface of the circuit board 4, which are located outside the signal pin 2, and one auxiliary signal pin 3 is provided on one mounting position to facilitate the arrangement of the auxiliary signal pin 3. One to four auxiliary signal pins 3 may be provided on the circuit board 4. When the number of the auxiliary signal pins 3 is less than the number of mounting positions, any mounting position may be selected to install the auxiliary signal pin 3.

The outer side of the male plug body 1 can be sleeved with a metal shell 31 as needed to improve the firmness of the lightning male plug; or the metal shell 31 can be omitted as needed to simplify the structure and reduce costs. When the metal shell 31 is sleeved on the outer side of the male plug body 1, the metal shell 31 needs to be processed to have an avoidance position for the auxiliary signal pin 3 to leave a gap between the auxiliary signal pin 3, and the metal shell 31 is different from the existing metal shell 31 and does not overlap with the empty pin to prevent the metal shell 31 from being electrically connected. At this time, the groove of the metal shell 31 located on the side of the male plug body 1 can be hollowed out, an insulating layer can be set, or no treatment can be done.

Of course, the above is just an example description, and the lightning male connector can also be set in other ways.

When the male connector is another male connector, such as a Type-C male connector, the auxiliary signal pin can be set in the same way as the auxiliary signal pin of the lightning male connector. For example, the metal shell of the Type-C male connector can be constructed as an auxiliary signal pin to overlap with the empty pin of the female connector; or a metal contact can be set as an auxiliary signal pin, and the setting position of the auxiliary signal pin is specifically arranged according to the shape of the male connector body. The female connector that is inserted into the Type-C male connector can be the same as the existing one.

The data line of the present application includes a transmission line and a male connector connected to the transmission line. The male connector is the above-mentioned male connector. In the data line of the present application, an auxiliary signal pin is added to increase the signal or electrical transmission line, thereby improving the use occasions of the male connector. For example, when the signal pin is used for charging, the auxiliary signal pin can be used to transmit an audio signal, so that the male connector can be used as an audio transmission device while charging.

Regardless of which of the above embodiments, the auxiliary signal pin 3 and the signal pin 2 are connected to different transmission lines so that the auxiliary signal pin 3 can transmit a signal or electricity through the transmission line. For example, in Embodiment 1, 16 metal terminals 21 and two connecting terminals 33 are exposed at the rear end of the male plug body 1, and the two connecting terminals 33 are respectively connected to two transmission lines, and 2 metal terminals 21 of the 16 metal terminals 21 (the 2 metal terminals 21 corresponding to the front and back positions of the male plug body 1) are connected to one transmission line, and a total of 10 transmission lines are set. Of course, 9 transmission lines can also be set, and one of the connecting terminals 33 is not connected to the transmission line. In Embodiment 2, no matter how many auxiliary signal pins 3 are set, 10 transmission lines can be set.

After the male connector and the transmission line are welded, a plastic shell can be wrapped around the outside of the male connector and the transmission line to prevent leakage of the data line and improve the aesthetics and service life of the data line.

The auxiliary signal pin 3 can be selectively used for grounding or transmitting signals or transmitting electricity. When the auxiliary signal pin 3 can be used for grounding, a grounding wire or the like can be set in the data line.

The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
