Description

[Technical Field]

[0001] This utility model belongs to the field of connector technology, and in particular relates to a connector that can automatically detect the insertion status. [Background Technology]

[0002] When a female connector and a male connector are plugged into each other, if it is necessary to sense the plugging action of the male connector, a detection terminal and a short-circuit spring are generally provided inside the female connector to transmit the plugging signal through the electrical contact between the detection terminal and the short-circuit spring. Existing technology generally uses a short-circuit detection method when the connector is pulled out. For example, a network communication socket with a short-circuit cap disclosed in Chinese Patent Publication No. CN202423732U, when the male connector is inserted, the male connector presses the detection terminal away from the short-circuit spring, thereby causing the detection terminal to contact the short-circuit spring. When the connector male is pulled out, the detection terminal springs back to contact the short-circuit spring, resulting in a short circuit. After repeated insertion of the male, the elasticity of the detection terminal decreases. When the connector male is pulled out, the detection terminal may not spring back to contact the short-circuit spring due to reduced elasticity, thus remaining in an open state. Therefore, even when the connector male is not inserted, the detection terminal may remain in an open state due to reduced elasticity, leading to both situations where the connector male is not inserted and misjudgments where the connector male is inserted, thus affecting the normal operation of the entire circuit.

[0003] Therefore, it is necessary to provide a connector that can automatically detect the mating status to solve the above-mentioned technical problems. [Utility Model Content]

[0004] The main purpose of this invention is to provide a connector that can automatically detect the insertion status. It is simple and convenient to automatically detect the insertion status, and it can also solve the problem of misjudgment of the insertion status, thereby improving the service life of the connector.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a connector capable of automatically detecting the insertion status, comprising a plastic shell and a plastic insert installed inside the plastic shell. The plastic shell and the plastic insert together form a insertion cavity for inserting a male connector. The plastic insert is provided with a signal terminal, a detection terminal, and a short-circuit spring extending into the insertion cavity. When the male connector is not inserted, the detection terminal is not in contact with the short-circuit spring and is in an open state. After the male connector is inserted, the male connector presses the detection terminal toward the short-circuit spring, causing the detection terminal to elastically deform and thus contact the short-circuit spring, resulting in a short-circuit state.

[0006] Furthermore, the signal terminal includes a vertically extending first welding portion, a first retaining portion that bends horizontally to one side from the upper end of the first welding portion, and a first contact portion that extends obliquely upward from the end of the first retaining portion to the opposite side.

[0007] Furthermore, the detection terminal includes a vertically extending second welding portion, a second retaining portion that bends horizontally to one side from the upper end of the second welding portion, and a second contact portion that extends obliquely upward from the end of the second retaining portion to the opposite side.

[0008] Furthermore, the short-circuit spring includes a retaining body extending horizontally front to back and a first spring and a second spring protruding upward from both ends of one side of the retaining body. The first spring and the second spring both gradually protrude from both sides toward the middle to form a raised contact portion that contacts the second contact portion. The raised contact portion is located below the second contact portion.

[0009] Furthermore, the plastic insert includes a horizontal insert portion and a vertical insert portion. The horizontal insert portion is provided with a plurality of receiving grooves for positioning the first holding portion and the second holding portion. The inner side of the connection between the horizontal insert portion and the vertical insert portion is provided with a positioning groove for positioning the holding body. The first spring and the second spring both extend toward one side of the horizontal insert portion and are located above the horizontal insert portion.

[0010] Furthermore, one side of the plastic shell is provided with an insertion port for inserting a male connector, and the other opposite side is a mounting port for installing the plastic insert. The mounting port includes a bottom mounting port that mates with the horizontal insert portion and a vertical mounting port that mates with the vertical insert portion.

[0011] Furthermore, the plastic shell is provided with a first wedge-shaped limiting block on the upper side of the mounting port, a guide limiting block in the middle, and a limiting groove at the bottom. The plastic insert is provided with a wedge-shaped limiting part that cooperates with the first wedge-shaped limiting block for limiting, a guide hole that cooperates with the guide limiting block for guiding and limiting, and a second wedge-shaped limiting block that cooperates with the limiting groove for limiting at the corresponding positions.

[0012] Furthermore, the middle of the plastic shell extends downward with a plurality of first limiting baffles that block one side of the holding body and restrict the movement of the holding body, and a first clearance gap is formed between two adjacent first limiting baffles to avoid the signal terminal.

[0013] Furthermore, a second limiting baffle extends downward from the middle of the plastic shell and is located above the protruding contact portion. A second clearance gap is formed between the second limiting baffle, the first limiting baffle, and the inner wall of the plastic shell to avoid the detection terminal.

[0014] Compared with the prior art, the beneficial effects of this utility model of a connector capable of automatically detecting the insertion status are as follows: when the male head is not inserted, the detection terminal and the shorting spring are not in contact and are in an open state; after the male head is inserted, the male head presses the detection terminal towards the shorting spring, causing the detection terminal to elastically deform and thus contact the shorting spring, putting it in a short-circuit state. This allows for automatic detection of the insertion status, which is simple and convenient. Moreover, the change from an open state to a short-circuit state between the detection terminal and the shorting spring is achieved by the male head pressing the detection terminal and the shorting spring into contact, avoiding the problem of the detection terminal and the shorting spring failing to make contact. Therefore, it can solve the problem of misjudgment of the insertion status due to poor contact in the prior art, thereby improving the service life of the connector. [Attached Image Description]

Detailed Implementation Methods

[0030] Please refer to Figures 1-7 This embodiment is a connector 100 that can automatically detect the insertion status. It can detect whether the male connector is inserted. The connector 100 that can automatically detect the insertion status includes a plastic shell 1 and a plastic core 2 installed in the plastic shell 1. The plastic shell 1 and the plastic core 2 together form a insertion cavity 3 for the male connector to be inserted. The plastic core 2 is provided with a signal terminal 4, a detection terminal 5 and a short-circuit spring 6 that extend into the insertion cavity 3. When the male connector is not inserted, the detection terminal 5 and the short-circuit spring 6 are not in contact and are in an open state. After the male connector is inserted, the male connector squeezes the detection terminal 5 toward the short-circuit spring 6, causing the detection terminal 5 to elastically deform and thus contact the short-circuit spring 6, and is in a short-circuit state.

[0031] The signal terminal 4 includes a vertically extending first soldering portion 41, a first retaining portion 42 that bends horizontally to one side from the upper end of the first soldering portion 41, and a first contact portion 43 that extends obliquely upward from the end of the first retaining portion 42 to the opposite side.

[0032] The detection terminal 5 includes a vertically extending second welding portion 51, a second retaining portion 52 that bends horizontally to one side from the upper end of the second welding portion 51, and a second contact portion 53 that extends obliquely upward from the end of the second retaining portion 52 to the opposite side.

[0033] The short-circuit spring 6 includes a retaining body 61 extending horizontally from front to back, and a first spring 62 and a second spring 63 protruding upward from both ends of the retaining body 61. The first spring 62 and the second spring 63 are both inverted V-shaped. The first spring 62 and the second spring 63 gradually protrude from both sides towards the middle to form a raised contact portion 64 that contacts the second contact portion 53. The raised contact portion 64 is located below the second contact portion 53.

[0034] In this embodiment, the signal terminal 4 and the detection terminal 5 have the same structure and are both metal elastic elements with a large elastic deformation. Four signal terminals 4 and four detection terminals 5 are provided, with the four signal terminals 4 located in the middle. Two detection terminals 5 are provided on the front side and two on the rear side of each signal terminal 4. When the male connector is inserted into the insertion cavity 3, all four signal terminals 4 and four detection terminals 5 contact the metal terminals on the surface of the male connector to achieve electrical connection. Furthermore, all four signal terminals 4 and four detection terminals 5 are pressed downwards by the male connector, and the two front detection terminals 5 contact the protruding contact portion 64 of the first spring piece 62. When in a short-circuit state, the two rear detection terminals will contact the protruding contact portion 64 of the second spring 63 and be in a short-circuit state. When the male connector is inserted into the insertion cavity 3, the detection terminal 5 and the short-circuit spring 6 change from an open state to a short-circuit state, which can automatically detect the insertion state. It is simple and convenient. Moreover, the change from an open state to a short-circuit state between the detection terminal 5 and the short-circuit spring 6 is achieved by the male connector pressing the detection terminal and the short-circuit spring 6 into contact. There will be no problem that the detection terminal 5 and the short-circuit spring 6 cannot make contact. Therefore, it can solve the problem of misjudgment of insertion state detection due to poor contact in the prior art, and can also improve the service life of the connector.

[0035] In other embodiments, the structures of signal terminal 4 and detection terminal 5 may also be different, and can be set according to the actual structure, without limitation here.

[0036] In another embodiment, the number and location of the signal terminals 4 and the detection terminals 5 can be determined according to the actual circuit wiring and are not limited here.

[0037] The plastic insert 2 is L-shaped and includes a horizontal insert portion 21 and a vertical insert portion 22. The horizontal insert portion 21 is provided with a plurality of receiving grooves 23 for positioning the first holding portion 42 and the second holding portion 52. The first welding portion 41 and the second welding portion 51 extend to the lower part of the horizontal insert portion 21, and the first contact portion 43 and the second contact portion 53 extend obliquely to the upper part of the horizontal insert portion 21. A positioning groove 24 for positioning and holding body 61 is provided on the inner side of the connection between the horizontal insert portion 21 and the vertical insert portion 22. The first spring piece 62 and the second spring piece 63 both extend toward one side of the horizontal insert portion 21 and are located above the horizontal insert portion 21.

[0038] The plastic housing 1 has an insertion port 11 for inserting a male connector on one side and an installation port 12 for installing the plastic insert 2 on the opposite side. The installation port 12 includes a bottom installation port that mates with the horizontal insert 21 and a vertical installation port that mates with the vertical insert 22. The plastic insert 2 and the plastic housing 1 are both elastic. When the plastic insert 2 is installed in place, the end of the horizontal insert 21 abuts against the side wall at the bottom of the plastic insert 2, and the upper end of the vertical insert 22 abuts against the inner wall at the upper end of the plastic insert 2. The plastic shell 1 has a first wedge-shaped limiting block 13 on the upper side of the mounting port 12, a guide limiting block 14 in the middle, and a limiting groove 15 at the bottom. The plastic insert 2 has a wedge-shaped limiting part 25 that cooperates with the first wedge-shaped limiting block 13 for limiting, a guide hole 26 that cooperates with the guide limiting block 14 for guiding and limiting, and a second wedge-shaped limiting block 27 that cooperates with the limiting groove 15 for limiting at the corresponding positions. The first wedge-shaped limiting block 13 is disposed on the inner side of the upper wall of the plastic shell 1. The wedge-shaped limiting part 25 is engaged with the inner side of the first wedge-shaped limiting block 13, which can restrict the plastic ferrule 2 from detaching from the plastic shell 1. The second wedge-shaped limiting block 27 is disposed on the upper surface of the horizontal ferrule part 21. The second wedge-shaped limiting block 27 is engaged with the limiting groove 15, which can further restrict the plastic ferrule 2 from detaching from the plastic shell 1, thereby improving the reliability of the connector. When the plastic ferrule 2 is installed into the plastic shell 1, the cooperation between the guide limiting block 14 and the guide hole 26 can not only play a guiding role, but also play a role in preventing errors. Furthermore, it can also restrict the movement of the plastic ferrule 2 in the front-back direction and the up-down direction within the plastic shell 1.

[0039] The retaining body 61 is flat, and correspondingly, the positioning groove 24 and the retaining body 61 are shaped like horizontal grooves. To prevent the short-circuit spring 6 from dislodging from the positioning groove 24, a plurality of first limiting baffles 16 extend downward from the middle of the plastic shell 1, blocking one side of the retaining body 61 and restricting its movement. The first limiting baffles 16 are located on the side with the first spring 62 and the second spring 63, which can restrict the retaining body 61 from dislodging from the positioning groove 24, thereby preventing the positions of the first spring 62 and the second spring 63 from shifting. Since the signal terminal 4 and the detection terminal 5 extend upward at an angle, a first clearance gap 17 is formed between two adjacent first limiting baffles 16 to avoid the signal terminal 4. Each first clearance gap 17 accommodates one signal terminal 4, which can prevent interference caused by the elastic deformation of the signal terminal 4 when the male connector is inserted, thereby improving safety and reliability. Therefore, the first limiting baffles 16 not only restrict the short-circuit spring 6 from dislodging from the positioning groove 24, but also improve safety and reliability. Since the first spring 62 and the second spring 63 are higher than the holding body 61, and both the first spring 62 and the second spring 63 have multiple detection terminals 5, in order to avoid interference between the multiple detection terminals 5, a second limiting baffle 18 extends downward from the middle of the plastic shell 1 and is located above the protruding contact portion 64. The structure of the second limiting baffle 18 is the same as that of the first limiting baffle 16, except that the second limiting baffle 18 is located above the first limiting baffle 16. A second clearance gap 19 is formed between the second limiting baffle 18, the first limiting baffle 16, and the inner wall of the plastic shell 1 to avoid the detection terminals 5. Each second clearance gap 19 contains one detection terminal 5, which can prevent interference when the detection terminal 5 is elastically deformed when the male head is inserted, thereby improving safety and reliability.

[0040] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
