Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples or figures are illustrative of the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1, 2 and 4, it comprises a female equipment socket 1 and a data line socket 2, wherein, as shown in fig. 7, the outer side of a shell 9 of the female equipment socket 1 is provided with two rows of output terminals 12 which are uniformly distributed; the two rows of output terminals 12 are connected with a data processing end inside the electronic equipment; the equipment female socket 1 is detachably mounted at the data input end of the electronic equipment through four fixing plates 10 which are symmetrically distributed on two sides of a shell 9 of the equipment female socket; as shown in fig. 6, the data line socket 2 is provided with a plug 6, and the data line socket 2 is connected with the equipment female socket 1 through the inserting fit of the plug 6 and the equipment female socket 1; the method is characterized in that: the equipment female socket 1 comprises a shell 9, an inserting plate 11, a supporting bar 18, a mounting slide block 19, a trigger plate spring 13 and a return spring 15, wherein as shown in fig. 8 and 12, one end of the inserting plate 11 is fixedly mounted on the inner end face of the shell 9, and the inserting plate 11 is provided with a data transmission pin which is electrically connected with a mobile phone; as shown in fig. 11 and 12, two supporting bars 18 are symmetrically installed on the upper and lower sides of the inserting plate 11 through sliding fit, and two installation sliders 19 are symmetrically installed on the left and right sides of the inserting plate 11 through sliding fit; as shown in fig. 14, 16 and 17, two first pin shafts 41 are symmetrically installed at two ends of the supporting bar 18, and two second pin shafts 42 are vertically symmetrically installed on the two installation sliders 19; the axes of the four first pins 41 and the four second pins 42 are in the same plane, and the plane is perpendicular to the direction in which the data line socket 2 is inserted into the equipment female socket 1; one end of each of the four trigger plate springs 13 is rotatably mounted on a first pin shaft 41 mounted on one corresponding end of the two support bars 18, and the other end of each of the four trigger plate springs 13 is rotatably mounted on a second pin shaft 42 mounted on one corresponding mounting slider 19 of the two mounting sliders 19; two trigger plate springs 13 positioned on the same side in the four trigger plate springs 13 are distributed in a left-right staggered manner; a return spring 15 which has a return effect on the two mounting sliders 19 is also mounted in the housing 9. The reason for designing the staggered distribution of the two trigger plate springs 13 on the same side is to increase the lengths of the two trigger plate springs 13, namely, increase the pre-pressure of the trigger plate springs 13, and ensure that the four trigger plate springs 13 have enough elasticity to drive the two support strips 18 to slide; under the normal non-triggered state, the force of the four trigger plate springs 13 on the two support bars 18 and the two mounting sliders 19 is a driving force in the vertical up-down direction, and under the driving force, the two support bars 18 and the two mounting sliders 19 are in a balanced state under the action of respective rails; when the two mounting sliders 19 are triggered to move backwards, the four trigger plate springs 13 have oblique component force deviating from the vertical direction to the driving force of the two support bars 18 and the two mounting sliders 19, and under the action of the oblique component force, the balance among the four trigger plate springs 13, the two support bars 18 and the two mounting sliders 19 is broken, and the two support bars 18 slide forwards under the component force; the four trigger leaf springs 13 are designed with a pre-stress.

As shown in fig. 15, the lower end of the swing plate 14 has an avoidance step 37, and the front end of the swing plate 14 has a smooth arc surface, as shown in fig. 8 and 12, the rear end of the swing plate 14 is rotatably mounted with the mounting rotating shaft 26, and the two swing plates 14 are symmetrically mounted on the inner side of the housing 9 through the corresponding mounting rotating shafts 26; the two swing plates 14 are positioned at the upper side and the lower side of the two support bars 18, and the two support bars 18 are in one-to-one corresponding contact with the side surfaces of the two swing plates 14 with the avoidance steps 37.

In a normal non-triggered state, the two swinging plates 14 are in a horizontal state under the support of the two support bars 18, and the two swinging plates 14 in the horizontal state tightly support the inserted data line socket 2; one end of the data wire insertion opening 2 extending into the shell 9 is in pressing contact with both sides of the supporting bar 18.

In the invention, under the state that a data line socket 2 is normally inserted into an equipment female socket 1, a first slot 7 formed in the data line socket 2 is embedded in an upper swing plate 14 and a lower swing plate 14, a second slot 8 formed in the data line socket 2 is embedded in an inserting plate 11, the two swing plates 14 are supported by two supporting bars 18 and are in a horizontal state, and the first slot 7 formed in the data line socket 2 is in close contact; when the two supporting bars 18 are triggered to slide forwards and the two supporting bars 18 are in contact fit with the avoidance steps 37 formed on the two swing plates 14, the two supporting bars 18 lose the support for the two swing plates 14, the two swing plates 14 swing downwards, and a gap appears between the two swing plates 14 and the first slot 7 formed in the data line socket 2, so that the data line socket 2 can be better ensured to exit the equipment female socket 1.

Under the state that the data line socket 2 is inserted into the equipment female socket 1, the data line socket 2 swings left and right relative to the equipment female socket 1 and pushes the two mounting sliders 19 to move backwards, the two mounting sliders 19 move backwards and drive the two support bars 18 to slide forwards through the corresponding trigger plate springs 13, and the support bars 18 push the data line socket 2 outwards; meanwhile, the two support bars 18 are in contact fit with the avoidance steps 37 formed on the two swing plates 14, at the moment, the two support bars 18 lose support for the two swing plates 14, the two swing plates 14 swing downwards, a gap is formed between the two swing plates 14 and the first slot 7 formed in the data line socket 2, and the tightening effect on the data line socket 2 is lost.

As shown in fig. 13, two first trapezoidal guide slots 21 are symmetrically formed on both upper and lower end surfaces of the board 11, two sliding slots 23 are symmetrically formed on both side surfaces of one end of the board 11 fixed to the inner end surface of the housing 9, and two second trapezoidal guide slots 22 are symmetrically formed in both the two sliding slots 23; as shown in fig. 16, two first trapezoidal guide blocks 39 are symmetrically installed on the support bars 18, as shown in fig. 10 and 11, the two support bars 18 are respectively installed on the upper and lower sides of the board 11 through the two first trapezoidal guide blocks 39 thereon and the first trapezoidal guide grooves 21 opened on the board 11 in a sliding fit manner; the two first trapezoidal guide blocks 39 are in sliding fit with the first trapezoidal guide grooves 21 to play a role in guiding and limiting the corresponding support bars 18, so that the support bars 18 can only slide forwards along the corresponding first trapezoidal guide grooves 21; as shown in fig. 16, the mounting sliders 19 are provided with second trapezoidal guide blocks 29, and as shown in fig. 10 and 11, the two mounting sliders 19 are mounted in the two sliding grooves 23 through the second trapezoidal guide blocks 29 in sliding fit with the second trapezoidal guide grooves 22 formed in the insert plate 11; as shown in fig. 16 and 17, one end of each of the two return springs 15 is fixedly mounted on the corresponding mounting slider 19, and the other end of each of the two return springs 15 is fixedly mounted on the inner end surface of the housing 9; the second trapezoidal guide block 29 is in sliding fit with the second trapezoidal guide groove 22 to guide and limit the installation sliding block 19, so that the installation sliding block 19 can only slide backwards along the corresponding second trapezoidal guide groove 22.

As shown in fig. 12 and 16, two ends of the two support bars 18 are respectively and fixedly installed with a first L-shaped trigger plate 24, two installation sliders 19 are respectively and fixedly installed with a second L-shaped trigger plate 25, the upper and lower ends of the two second L-shaped trigger plates 25 are respectively and symmetrically installed with two force transmission plates 40, the two force transmission plates 40 installed on the same second L-shaped trigger plate 25 are in contact fit with the two first L-shaped trigger plates 24 on the same side, and the two force transmission plates 40 are located at the rear sides of the two first L-shaped trigger plates; in the state that the data line socket 2 is inserted into the equipment female socket 1, one end of the data line socket 2 inserted into the equipment female socket 1 is in contact with the four first L-shaped trigger plates 24; in a normal non-triggered state, the four first trapezoidal guide grooves 21 formed in the inserting plate 11 limit the backward movement of the two supporting bars 18.

The four first L-shaped trigger plates 24 have elasticity. In the invention, under the condition that the data line socket 2 is inserted into the equipment female socket 1, one end of the data line socket 2 inserted into the equipment female socket 1 is contacted with four first L-shaped trigger plates 24; when the data line socket 2 swings left and right relative to the equipment female socket 1, one end of the data line socket 2 inserted into the equipment female socket 1 extrudes the two first L-shaped trigger plates 24 on one side, and in order to ensure that when the data line socket 2 swings left and right relative to the equipment female socket 1, the two mounting sliding blocks 19 are triggered preferentially and move backwards, and then the four trigger plate springs 13 drive the supporting bars 18 to slide forwards, so that the data line socket 2 exits from the equipment female socket 1 and is disconnected; therefore, the first L-shaped trigger plates 24 are designed to have elasticity, when the two first L-shaped trigger plates 24 on one side are pressed, the two first L-shaped trigger plates 24 drive the supporting bars 18 on which the two first L-shaped trigger plates 24 are installed to move backwards, and because the supporting bars 18 are limited by the first trapezoidal guide grooves 21 formed in the inserting plate 11 to move backwards, the two first L-shaped trigger plates 24 on the side are deformed after being pressed, and the second L-shaped trigger plates 25 in contact with the two first L-shaped trigger plates 24 are pressed through deformation, so that the installation slide blocks 19 on the same side are pushed to move backwards through the second L-shaped trigger plates 25.

As shown in fig. 5, 9 and 12, two support blocks 5 are symmetrically mounted on the inner end surface of the housing 9, and one ends of the two support blocks 5 away from the inner end surface of the housing 9 have arc surfaces; under the state that the data line socket 2 is inserted into the equipment female socket 1, one end of the data line socket 2 inserted into the equipment female socket 1 is in contact with the highest point of the upper cambered surfaces of the two supporting blocks 5. The support block 5 functions to provide a side-to-side swinging support for the data line socket 2 inserted into the female socket 1 of the device.

As shown in fig. 9 and 12, four pressing plate springs 17 are mounted on the inner end surface of the housing 9 in a vertically symmetrical manner, and one end of each pressing plate spring 17 away from the inner end surface of the housing 9 is in contact with and press-fitted to the two swing plates 14. The function of the pressure plate spring 17 designed by the invention is that when the corresponding swing plate 14 loses the supporting function of the corresponding supporting bar 18, one end of the pressure plate spring 17 contacting with the corresponding swing plate 14 presses the corresponding swing plate 14 downwards, so that the swing plate 14 swings downwards.

As shown in fig. 15, two limit plates 38 are symmetrically installed on each of the two swing plates 14, an arc surface 35 is provided at the front end of each limit plate 38, and a slot 36 is provided on each limit plate 38.

In the invention, under the state that the data line socket 2 is normally inserted into the equipment female socket 1, the four semicircular protrusions 3 arranged on the data line socket 2 are just clamped in the four clamping grooves 36 formed in the four limiting plates 38, and the data line socket 2 inserted into the equipment female socket 1 is limited by the matching of the four clamping grooves 36 and the four semicircular protrusions 3; when the data line socket 2 swings left and right relative to the equipment female socket 1, the four semicircular protrusions 3 and the corresponding clamping grooves 36 are dislocated and disengaged, and the data line socket 2 cannot be influenced to exit the equipment female socket 1; when the data line socket 2 swings up and down relative to the equipment female socket 1, the four semicircular protrusions 3 and the corresponding clamping grooves 36 can be dislocated and disengaged, and the data line socket 2 can not be influenced to exit the equipment female socket 1.

The return spring 15 is a compression spring.

The four semicircular bulges 3 arranged on the data wire socket 2 are made of rubber materials. Rubber materials have elasticity, make things convenient for inserting and extracting of data line socket 2, still can not influence equipment female socket 1 spacing to data line socket 2 simultaneously.

The limit plate 38 is fixedly mounted on the wobble plate 14 by welding.

The invention designs the interface of the mobile phone, although the structure is relatively complicated compared with the traditional structure, on the premise of large annual demand of the mobile phone, the mass production of the interface can greatly reduce the cost of the interface; the invention avoids the times of disassembling the mobile phone in the life cycle of the mobile phone by using a relatively complex structure, prolongs the service life of the mobile phone to a certain extent, and ensures that information is not leaked.
