Signal connector with short circuit protection structure

The present invention is a signal connector, especially a signal connector having a short-circuit proof structure, which prevents foreign matter (such as metal chips) from falling into the connection hole, thereby effectively preventing foreign matter from being used to transmit different polarities. A short circuit occurs between the power supply or the terminals of different types of signals.

According to the advancement of communication technology and electronic technology, electronic devices with various functions, such as mobile power devices that can be carried around for continuous power supply of mobile phones, mobile phones that enable people to communicate at both ends of the world, can satisfy people anytime, anywhere. Listening to the music of the Walkman and the Personal Computer that can help people deal with things... have become indispensable tools for modern people's lives and work. Nowadays, different kinds of electronic devices can be integrated into one another, making it impossible to use the mobile phone to listen to music, or to use the personal computer to make calls, etc., is no longer an unreachable dream. In order to receive external electronic signals and power, the electronic devices usually have a signal connector disposed on the body of each electronic device. The signal connector is used to transmit electronic components or power supply connecting components or accessory accessories. The main function is to provide bridging between various electronic devices, and to ensure that the electronic signals between them can be accurately transmitted, so that the electronic devices can be connected into a complete system by the signal connectors, thereby transmitting electrons to each other. Signals or power supplies, each of which has different types and structures depending on the application object, frequency, power and application environment, and is widely used in computers and computer weeks. In the side equipment or industrial equipment, telecommunications and communications, automobiles, transportation, household appliances, medical products, etc., it is an indispensable component of the electronic device to achieve a predetermined function.

However, since each of the signal connectors has a socket, a foreign object (such as metal shavings) is accidentally dropped into the connector hole when the signal connector is not used frequently. The insertion of the signal connector into an electronic device without the knowledge of the user will also result in the transmission of the different polarity power sources or different types of signals in the signal connector. An electrical short circuit between the terminals causes damage to the related electronic components, thereby greatly reducing the service life of the electronic device or the signal connector.

Therefore, the creators have thought of designing a signal connector with a short-circuit-proof structure in view of the aforementioned problems and deficiencies of the conventional signal connector, which is an important subject to be solved here.

1 is an exploded perspective view of a preferred embodiment of the present invention; and FIG. 2 is an exploded perspective view of a preferred embodiment of the present invention.

The present invention is a signal connector having a short-circuit proof structure, as shown in FIGS. 1 and 2, which is a preferred embodiment of the present invention. The signal connector 1 includes a first connector 11 and a second connection. The first connector 11 includes a first insulating base 111 and a first metal housing 113. The first end of the first insulating base 111 is convexly provided with a tongue 1113, and the first A plurality of first connecting terminals 115 are embedded in the insulating base 111. One end of the first connecting terminals 115 is exposed on one side of the tongue plate 1113, and the other end is the first insulating seat 111. The first connection terminal 115 is used for transmitting power signals. In practical applications, the first connection terminal 115 can also be designed to transmit other interfaces. The type of signal, not limited by the power signal, is first and foremost.

A first spacer portion 117 is disposed on the top surface of the tongue plate 1113. The first spacer portion 117 is located between the first connection terminals 115 and is parallel to one end of the first connection terminals 115.

The first recess 127 Corresponding to the position of the first spacing portion 117, the second connecting terminal 125 is divided into two terminals for respectively transmitting different polarity power sources or different kinds of signals; the second metal housing 123 The configuration is matched with the second insulating base 121 to enable the second insulating base 121 to be assembled. The second metal housing 123.

Referring to FIGS. 1 and 2, the first connection terminals 115 further include a positive connection terminal 115a and a negative connection terminal 115b. The length of the positive connection terminal 115a is smaller than the negative connection terminal 115b to the tongue. In the case where the board 1113 is inserted into the insertion slot 1211, the second connection terminal 125 is prevented from first touching the positive connection terminal 115a, thereby causing the positive connection terminal 115a to generate a spark, so that the first and second connectors are The related parts of 11, 12 cause burnt or malfunction problems.

In this manner, when the first connector 11 is inserted into the second connector 12, the first and second connection terminals 115 and 125 respectively transmit the same polarity power source or the same type of signal. When the corresponding terminal phase is electrically connected, the first spacer portion 117 can be engaged with the first recess 127 such that the accommodating space 1213 is separated into two independent spaces, and accordingly, if there is a small foreign matter If the first spacer 117 and the first recess 127 are not able to be smoothly fitted, the first spacer 117 and the first recess 127 may be smoothly inserted. The problem of the presence of the foreign matter can be immediately known, and the short circuit between the terminals of the first connection terminal 115 (or the second connection terminal 125) for transmitting different polarity power sources or different types of signals can be effectively avoided.

The second spacer portion 118 is located between the third connection terminals 116 and is parallel to one end of the third connection terminals 116. The inner wall surface of the insertion slot 1211 corresponds to the third connection terminals 116. And a plurality of fourth connecting terminals 126 and a second recess 128 are recessed in the second spacer portion 118, and the second recess 128 is located between the fourth connecting terminals 126, and One end of the fourth connection terminal 126 is parallel to each other, and the position of the second groove 128 corresponds to the position of the second spacer 118.

In the preferred embodiment of the present invention, the third connection terminals 116 further include a positive connection terminal 116a and a negative connection terminal 116b, and the position of the positive connection terminal 116a in the third connection terminal 116 is Corresponding to the position of the negative connection terminal 115b in the first connection terminal 115, when the user inserts the first connector 11 into the second connector 12, the user does not need to identify whether the first connector 11 is It can be directly or reversely inserted into the second connector 12.

According to the above, it is only the preferred embodiment of the present creation, but the author of the present invention The scope of Zhang's rights is not limited to this. Anyone who is familiar with the art, according to the technical content disclosed in this creation, can easily think of the equivalent changes, and should not fall within the protection scope of this creation.
