Description

Technical Field

[0001] The invention relates to the technical field of electronic connectors, and in particular to an electrical connector capable of measuring the number of plugging and unplugging times. Background Art

[0002] Electrical connectors are mainly used for electrical connections between circuit systems and are widely used in industries such as manned spaceflight, satellite communications, national defense equipment, and automobile manufacturing. With the advancement of science and technology and the upgrading of national defense weapons and equipment, higher requirements are placed on the quality and reliability of electrical connectors.

[0003] In application scenarios where electrical connectors need to be repeatedly plugged and unplugged, it is necessary to continuously ensure that the electrical connector and the entire circuit are in a good state of connectivity. The butt end is plugged into the electrical connector to achieve circuit connectivity. When the butt end is continuously plugged and unplugged from the electrical connector, the contact part of the electrical connector will be subject to certain wear and tear. Moreover, each electrical connector has a certain plug-in and unplug life. When this number of plug-in and unplugging times is exceeded, the wear of the electrical connector will become more serious, and may even cause problems such as poor contact and breakage in the electrical connector, thereby affecting the performance and stability of the electrical connector, and further affecting the stability of the connected circuit. Summary of the invention

[0004] In order to solve the above technical problem, the present invention provides an electrical connector capable of measuring the number of plugging and unplugging operations.

[0005] The present invention is achieved through the following technical solutions.

[0007] Preferably, the housing comprises a connecting portion and a containing portion, the connecting portion is sleeved on the connecting base, an containing cavity is formed between the containing portion and the outer peripheral side of the connecting base, and a cover plate is provided on the end surface of the containing cavity.

[0008] Preferably, the plug-in detection mechanism comprises a spring pin, a spring and a sensing element, wherein the spring pin is slidably inserted into the connecting portion, one end of the spring pin is inserted into the accommodating cavity, and the other end is placed outside the connecting base; one end of the spring is connected to the spring pin, and the other end is in contact with the sensing element, and the sensing element is arranged in the accommodating cavity.

[0009] Preferably, the signal acquisition mechanism includes a circuit board, a battery and a display screen. The circuit board is installed in the accommodating cavity. The circuit board is electrically connected to the sensing element. The circuit board is also electrically connected to the display screen. The display screen is arranged outside the accommodating portion. The battery is connected to the circuit board and the battery is placed in the accommodating cavity.

[0010] Preferably, a sealing gasket is provided between the housing and the cover plate.

[0011] Preferably, a connecting ring is sleeved on the connecting base, and one side of the connecting ring is in contact with an end of the spring pin away from the spring.

[0015] The beneficial effects of the present invention are:

[0016] 1. When the docking end is plugged into the connection base, the spring pin is subjected to pressure in the direction of the spring through the docking end, so that the spring pin moves into the accommodating cavity to push the spring to contract. At the same time, part of the thrust causes the spring to conflict with the sensing element, so that the sensing element is subjected to pressure. The sensing element feeds back the pressure signal to the circuit board, and the circuit board then feeds back the processed signal to the display screen. The display screen shows the cumulative number of signals fed back by the sensing element to the circuit board, and the number of plugging and unplugging of the docking end on the electrical connector can be intuitively observed. When the number of plugging and unplugging of the docking end on the electrical connector reaches the upper limit of the number of plugging and unplugging of the electrical connector, the electrical connector is replaced in time. It has an early warning prompt function to avoid poor circuit contact during the use of the electrical connector, thereby ensuring the safety performance between circuits.

[0017] 2. The spring pin and the docking end are separated by a connecting ring so that the connecting end and the docking end do not come into direct contact. On the one hand, the docking end is protected during the plug-in and unplug-out counting process, and on the other hand, the plug-in and unplug-out counting process is avoided as much as possible to affect the flow of the electrical connector circuit.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] In the embodiments of this application, refer to Figure 1 and Figure 2 , including a shell, the shell is composed of a connecting base 3 and a shell 2, the connecting base 3 is connected to a base assembly 1, and is used for an electrical connector to form a channel for signal transmission;

[0025] The outer shell 2 is sleeved on the connecting base 3, and the outer shell 2 includes a connecting part 21 and a accommodating part 22. The connecting part 21 is fixedly connected to the connecting base 3, and an accommodating chamber 4 is formed between the accommodating part 22 and the outer peripheral side of the connecting base 3; a limiting groove 18 is also provided on the inner side wall of the accommodating part 22, and the limiting groove 18 is arranged at the opening of the accommodating part 22. A cover plate 12 is provided on the limiting groove 18, and a sealing gasket 11 is provided between the limiting groove 18 and the cover plate 12. A plurality of threaded holes are provided on the sealing gasket 11 and the cover plate 12, and a plurality of threaded holes are threadedly penetrated by screws 13 and are threadedly connected to the bottom wall of the limiting groove 18, and the cover plate 12 and the sealing gasket 11 are fixed to the limiting groove 18, so that the cover plate 12 and the sealing gasket 11 seal the open end of the accommodating part 22, and the accommodating chamber 4 is in a closed state, so that the interior of the accommodating chamber 4 has a dustproof and waterproof effect.

[0026] In the embodiments of this application, refer to Figure 2The connection base 3 is provided with a plug-in detection mechanism, and the connection base 3 is also provided with a signal collection mechanism.

[0027] In the embodiments of this application, refer to Figure 1 and Figure 2 The plug-in detection mechanism includes a spring needle 5, a spring 6 and a sensing element 7. A slide groove 19 is provided on the connecting portion 21. One end of the slide groove 19 is communicated with the accommodating cavity 4, and the other end is communicated with the outside of the connecting base 3. The spring needle 5 is slidably inserted into the slide groove 19. One end of the spring needle 5 penetrates into the accommodating cavity 4, and the other end is placed on the outside of the connecting base 3; one end of the spring 6 is connected to the spring needle 5, and the other end is in contact with the sensing element 7. The sensing element 7 is fixedly arranged in the accommodating cavity 4. By hitting the spring needle 5, the spring 6 is pushed by the spring needle 5, so that the spring 6 is compressed and one end of the spring 6 also contacts the sensing element 7, so that the sensing element 7 is subjected to pressure from the spring 6, thereby realizing signal collection.

[0028] In the embodiments of this application, refer to Figure 1 and Figure 2 The signal acquisition mechanism includes a circuit board 9, a battery 8 and a display screen 10. The circuit board 9 is electrically connected to the sensing element 7. The inner side of the circuit board 9 is set in a semicircular arc shape, which is convenient for installing the circuit board 9 in the accommodating cavity 4, while avoiding affecting the installation of the spring 6 and the sensing element 7; the circuit board 9 is also electrically connected to the display screen 10, and a card slot 17 is opened through the shell 2. The display screen 10 is carded in the card slot 17, which is convenient for viewing the data on the display screen 10; the battery 8 is placed in the accommodating cavity 4, and a socket is provided on the circuit board 9. The battery 8 is provided with a plug. The plug is adapted to be connected with the socket, which is convenient for the battery 8 to power the circuit board 9 and the sensing element 7, and also realizes the detachable connection between the battery 8 and the circuit board 9, and is convenient for replacing the battery 8.

[0029] The battery 8 continuously provides power to the circuit board 9 and the sensing element 7. At the same time, a detection sensing module and a micro control unit module are arranged between the sensing element 7 and the circuit board 9. The pressure exerted on the sensing element 7 is detected by the sensing element 7 and the detection sensing module, and the detected signal is fed back to the circuit board 9 through the micro control processing module. At the same time, the signal is processed by the micro control processing module and displayed on the display screen 10.

[0030] In order to count the number of times the docking terminal 14 is plugged in and out, when the docking terminal 14 is connected to the connecting base 3, the spring pin 5 slides in the slide groove 19 into the accommodating cavity 4, so that the spring 6 is subjected to a thrust. At the same time, one end of the spring 6 is pressed against the sensing element 7 while the spring 6 is in a compressed state, so that the sensing element 7 is subjected to pressure. The sensing element 7 feeds back the pressure received to the circuit board 9, and the circuit board 9 processes multiple signals and displays the processed signals on the display screen 10, so that the number of times the docking terminal 14 is plugged in and out can be known intuitively.

[0031] In order to avoid direct contact between the spring pin 5 and the butt end 14, in the embodiment of the present application, refer to Figure 2 and Figure 3 An annular groove 16 is provided on the outer peripheral side of the connecting base 3, and a connecting ring 15 is sleeved in the annular groove 16. The connecting ring 15 and the two sides of the annular groove 16 are in clearance fit, so that the connecting ring 15 can achieve slight movement on both sides of the annular groove 16, and at the same time, one side of the connecting ring 15 contacts the end of the spring needle 5 away from the spring 6. When the docking end 14 is plugged into the connecting base 3, the end of the connecting ring 15 away from the spring needle 5 contacts the docking end 14, pushing the connecting ring 15 toward the spring needle 5, so that the sensing element 7 is subjected to a certain pressure, thereby realizing signal collection, and at the same time avoiding direct contact between the spring needle 5 and the docking end 14, protecting the docking end 14, thereby ensuring the circuit connection between the docking end 14 and the electrical connector, and avoiding circuit short circuit.

[0032] Each time the docking terminal 14 is plugged in, the connecting ring 15 pushes the spring pin 5 once, so that the sensing element 7 senses a signal once, and the accumulated signal times are accumulated in sequence and displayed on the display screen 10; each time the plugged docking terminal 14 is unplugged, the docking terminal 14 no longer presses against the connecting ring 15, and the connecting ring 15 has no thrust on the spring pin 5. At this time, the spring 6 acts on itself to move the spring pin 5 away from the accommodating cavity 4, so as to facilitate the spring pin 5 to return to its original position, thereby facilitating the collection and counting of signals when the docking terminal 14 is plugged into the electrical connector next time.

[0033] The working principle of this embodiment is as follows: when the docking end 14 is placed on the connecting base 3, the spring pin 5 is resisted by the connecting ring 15, pushing the spring pin 5 to move in the slide groove 19 and move into the accommodating chamber 4, pushing the spring 6 to contract. At the same time, some pressure causes the spring 6 to resist the sensing element 7, so that the sensing element 7 is subjected to pressure, and the pressure signal is fed back to the circuit board 9. The circuit board 9 then accumulates and processes the signal and feeds it back to the display screen 10. The accumulated signal count is displayed on the display screen 10, thereby counting and displaying the plug-in and unplugging times of the docking end 14. When the plug-in and unplugging times of the docking end 14 on the electrical connector reach the upper limit of the plug-in and unplugging times of the electrical connector, the electrical connector is replaced in time, which has an early warning prompt function to avoid poor circuit contact during use of the electrical connector, thereby ensuring the safety performance between circuits.
