Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector with stable mating. Background Technology

[0002] In the circuit connection system of electronic devices, connectors are key components for signal and current transmission, and the connection stability between the male and female heads is an important guarantee for signal and data transmission.

[0003] For example, a male connector has a pinhole on its insertion end. When it is inserted into a female connector, the pins on the female connector are inserted into the pinhole of the male connector and make close contact with the conductive sheet inside the pinhole. By utilizing the conductivity of the conductive sheet, signal and data transmission is achieved.

[0004] However, most of the conductive sheets inside the pinholes of male connectors are currently ordinary annular copper sheets, which are fixed to the inner wall of the pinhole by bonding, pre-embedding, or other methods. When the pins of the female connector are inserted into the pinhole, the outer circumference of the pins contacts the inner wall of the conductive sheet, so that the male connector and the female connector are fixed by the friction between the pins and the conductive sheet. This single fixing method has the problem of unstable connection when the connector is subjected to external forces such as vibration and impact, which leads to poor contact and transmission interruption.

[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a connector with stable insertion, comprising a wire connection segment, a plug segment, and a pinhole penetrating the wire connection segment and the plug segment, wherein a conductive sheet is disposed inside the pinhole; The conductive sheet is a tubular body with spring contacts inside. Multiple spring contacts are evenly arranged along the circumference of the conductive sheet, and one end of the conductive sheet protrudes from the surface of the wire connection section and is provided with a contact pin.

[0008] As a further embodiment of this utility model: the spring is formed by stamping and bending into the conductive sheet, and a groove is formed on the conductive sheet, and it is integrally connected with the conductive sheet.

[0009] As a further embodiment of this utility model: the spring sheet is composed of an inclined section and a pressing section, the inclined section is inclined inward toward the conductive sheet in the direction of the contact pin, and is connected to the pressing section.

[0010] As a further embodiment of this utility model: the spring is disposed near the end face of the plug segment.

[0011] As a further embodiment of this utility model: the power contact pin has an annular groove.

[0012] As a further embodiment of this utility model: a wire groove is provided at the end of the power contact pin, and the wire groove is connected to the annular groove.

[0013] As a further embodiment of this utility model: a plug is provided on the peripheral surface of the conductive sheet near the power receiving pin, and a slot corresponding to the plug and communicating with the pin hole is provided on the wire connecting section.

[0014] As a further embodiment of this utility model: the insert block is chamfered, and the internal shape of the slot is the same as that of the insert block.

[0015] As a further embodiment of this utility model: a positioning slot is provided on the plug segment.

[0016] As a further embodiment of this utility model: a retaining ring is provided between the line connecting section and the plug section.

[0017] Compared with the prior art, the beneficial effects of this technical solution are as follows: the wire connection section is used to connect with the external cable, and when the cable is sleeved on the wire connection section, the internal wires are electrically connected to the conductive plate through the contact pins. When the male connector is inserted into the female connector, the plug section mates with the female connector, and the pins on the female connector are inserted into the pin holes on the plug section and contact the conductive plate inside the pin hole. At the same time, the spring is squeezed to deform it until the pin of the female connector is inserted into place. At this time, the deformation of the spring generates a clamping force on the pin of the female connector. The multiple springs evenly arranged on the circumference work together to apply a clamping force on the pin, forming a fixing force, thereby improving the stability of the pin in the pin hole and avoiding poor contact and transmission interruption when subjected to external forces such as vibration and impact, thus improving the reliability of transmission.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 A connector with stable insertion includes a wire connection segment 1, a plug segment 2, and a pinhole 3 penetrating the wire connection segment 1 and the plug segment 2, wherein a conductive sheet 4 is disposed inside the pinhole 3. The conductive sheet 4 is a tubular body with springs 5 ​​inside. Multiple springs 5 ​​are evenly arranged along the circumference of the conductive sheet 4, and one end of the conductive sheet 4 protrudes from the surface of the wire connection section 1 and is provided with a power contact pin 6.

[0023] Specifically, the cable connection segment 1 is used to connect with an external cable (not shown in the figure). When the cable is sleeved on the cable connection segment 1, the internal wires are electrically connected to the conductive plate 4 through the electrical contact pin 6. When the male connector is inserted into the female connector, the plug segment 2 mates with the female connector, and the pins on the female connector are inserted into the pin holes 3 on the plug segment 2 and contact the conductive plate 4 inside the pin holes 3. At the same time, the spring sheet 5 is squeezed to deform it until the pins of the female connector are inserted into place. At this time, the deformation of the spring sheet 5 generates a clamping force on the pins of the female connector. The multiple spring sheets 5 evenly arranged on the circumference work together to apply a clamping force on the pins, forming a fixing force, thereby improving the stability of the pins in the pin holes and avoiding poor contact and transmission interruption when subjected to external forces such as vibration and impact, thus improving the reliability of transmission.

[0024] Based on the above embodiments, it is further proposed that the spring piece 5 is formed by stamping and bending into the conductive sheet 4, and a groove 7 is formed on the conductive sheet 4, which is integrally connected with the conductive sheet 4.

[0025] Specifically, the spring piece 5 and the conductive sheet 4 are an integral structure, requiring no additional splicing or welding. The spring piece 5 and the conductive sheet 4 maintain material continuity, avoiding gaps or weak stress points in the separate connection. The slot 7 formed during stamping and bending provides deformation space for the spring piece 5.

[0026] Based on the above embodiments, it is further proposed that the spring piece 5 is composed of an inclined section 8 and a pressing section 9. The inclined section 8 is inclined towards the conductive piece 4 in the direction of the contact pin 6 and is connected to the pressing section 9.

[0027] Specifically, the design of the inclined section 8 and the design of multiple spring contacts 5 evenly surrounding the periphery create a guide structure with a wide entrance and a narrow end inside the conductive sheet 4. When the plug section 2 is inserted into the female socket and the pin of the female socket is inserted into the pin hole 3, it contacts the inclined surface of the inclined section 8. The inclined section 8 gradually deforms as the pin is inserted, thereby ensuring smooth insertion of the pin and avoiding direct collision. After the pin is fully inserted, the pressing section 9 presses the pin to ensure that the pin is fixed in the pin hole 3.

[0028] Preferably, the spring piece 5 is positioned near the end face of the plug segment 2.

[0029] Based on the above embodiments, it is further proposed that the power contact pin 6 has an annular groove 10.

[0030] Specifically, the design of the annular groove 10 facilitates the winding of the wires for easy welding and fixing.

[0031] Based on the above embodiments, it is further proposed that a wire groove 11 be provided at the end of the power connection pin 6, and the wire groove 11 is connected to the annular groove 10.

[0032] Specifically, the opening of the wire passage groove 11 allows the wire to pass through the wire passage groove 11 before being wound around the annular groove 10, which can fix the wire and prevent problems such as the wire rotating or loosening.

[0033] Based on the above embodiments, it is further proposed that a plug 12 is provided on the peripheral surface of the conductive sheet 4 near the power receiving pin 6, and a slot 13 corresponding to the plug 12 and communicating with the pin hole 3 is provided on the wire connection section 1.

[0034] Specifically, when the conductive sheet 4 is installed inside the pinhole 3, whether by bonding or pre-embedding, the interlocking of the insert block 12 and the slot 13 can provide a fixing effect for the rotation direction of the conductive sheet 4, thereby preventing the conductive sheet 4 from becoming loose between the pinhole 3 under conditions of vibration, compression, or collision.

[0035] Preferably, the insert 12 is chamfered, and the internal shape of the slot 13 is the same as that of the insert 12.

[0036] Based on the above embodiments, it is further proposed that the plug segment 2 is provided with a positioning slot 14. The positioning slot 14 can prevent the male connector from being inserted into the wrong position when it is plugged into the female connector, which would cause the pin to not be inserted into the corresponding pin hole 3 and thus cause the pin to deform.

[0037] Based on the above embodiments, it is further proposed that a retaining ring 15 is provided between the line connecting section 1 and the plug section 2. The function of the retaining ring 15 is that when the line is assembled on the line connecting section 1, the retaining ring 15 can act as a support surface.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
