Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically to a novel three-contact connector compatible with different terminal pins. Background Art

[0002] In the field of electronic communications, connectors are key components for signal transmission, and their performance and stability directly affect the operation of the entire system. Traditional connector terminal designs often use a single-point contact method, which can meet basic signal transmission needs in most cases. However, in actual applications, due to environmental factors (such as dust, moisture, vibration, etc.), non-conductive foreign matter may adhere to or enter the contact area, resulting in poor contact between contact points, which in turn causes problems such as poor signal transmission and poor conduction. These problems not only affect the quality of signal transmission, but may also cause system instability or even failure. Therefore, we have made improvements to this and proposed a new three-contact connector that is compatible with different terminal pins.

[0003] For example, a Chinese patent (publication number CN208655956U) discloses an FPC connector with a contact terminal spacing of one millimeter, wherein the contact terminal includes a contact terminal body, a first contact foot, a second contact foot, a K foot and a protrusion, wherein the first contact foot and the second contact foot are symmetrically arranged on the upper two sides of the contact terminal body, respectively, the K foot is arranged on the lower side of the contact terminal body, the second contact foot and the K foot are on the same side, a protrusion is provided on the upper part of the first contact foot close to the side of the second contact foot, and a protrusion is also provided on the upper part of the second contact foot close to the side of the first contact foot, and the contact terminal body, the first contact foot, the second contact foot, the K foot and the protrusion are arranged as a whole. Utility Model Content

[0004] The technical problem to be solved by the embodiments of the utility model is that the connector terminal adopts a single-point contact method. Due to the influence of environmental factors, non-conductive foreign matter may adhere to or enter the contact area, resulting in poor contact between the contact points.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] As an improved manner of the present invention, the lower clamping arm is bent and the auxiliary clamping arm is inclined.

[0008] As an improved manner of the utility model, the side of the terminal body close to the lower clamp arm is fixedly connected to the upper clamp arm located above the lower clamp arm, and the side of the terminal body away from the lower clamp arm is fixedly connected to the welding foot.

[0009] As an improved manner of the utility model, a positioning protrusion is arranged on the top of the terminal body, and the positioning protrusion is used for positioning the terminal body during installation.

[0010] As an improvement of the utility model, a base structure is arranged between the plurality of terminal structures, the base structure comprises a first side seat and a second side seat, and a plurality of module bases are detachably connected between the first side seat and the second side seat.

[0011] As an improvement of the utility model, a plurality of mounting grooves are provided on the module base, the first side seat and the second side seat, the terminal structure is arranged in the mounting groove, and one end of the welding foot away from the terminal body extends out from the module base.

[0013] As an improvement of the present invention, the bottoms of the first side seat and the second side seat are both provided with conductive sheets, and the conductive sheets are used to conduct static electricity on the base structure.

[0014] As an improved manner of the utility model, a cover is provided between the second side seat and the first side seat, and the cover is rotatably connected between the second side seat and the first side seat.

[0016] Compared with the prior art, the embodiments of the present invention mainly have the following beneficial effects:

[0017] In order to solve the problem that in the prior art, the connector terminal adopts a single-point contact method, and due to the influence of environmental factors, non-conductive foreign matter may adhere to or enter the contact area, resulting in poor contact between the contact points, the present application sets a first contact, a second contact and a third contact.

Since the possibility of foreign matter affecting the contact point is reduced, the present design can significantly reduce the failure rate of the connector caused by poor contact.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present invention belongs; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Reference to "embodiments" herein means that specific features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] As described in the background technology, in the field of electronic communications, connectors are key components for signal transmission, and their performance and stability directly affect the operation of the entire system. Traditional connector terminal designs often adopt a single-point contact method, which can meet basic signal transmission requirements in most cases. However, in actual applications, due to environmental factors (such as dust, moisture, vibration, etc.), non-conductive foreign matter may adhere to or enter the contact area, resulting in poor contact between contact points, and then causing problems such as poor signal transmission and poor conduction. These problems not only affect the quality of signal transmission, but may also cause system instability or even failure.

[0032] In order to solve this technical problem, the utility model provides a novel three-contact connector which is compatible with different terminal pins.

[0033] Specifically, please refer to Figure 1 The new three-contact connectors compatible with different terminal pins include:

[0034] Several terminal structures 1 include a terminal body 101, one side of the terminal body 101 is connected to a lower clamp arm 104, the top of the lower clamp arm 104 is fixedly connected to an auxiliary clamp arm 105, the top of the auxiliary clamp arm 105 is provided with a third contact 108, and the top of the lower clamp arm 104 is also provided with a first contact 106 and a second contact 107.

[0035] The utility model provides a novel three-contact connector compatible with different terminal pins. By setting the first contact 106, the second contact 107 and the third contact 108, the setting of the first contact 106, the second contact 107 and the third contact 108 makes the terminal structure 1 provided in the present application have three contacts. Compared with the traditional single-point contact design, the design of three contacts enables the connector to maintain a more stable contact state when affected by external forces or environmental factors, thereby reducing the occurrence of poor contact; even if one of the contacts is affected by foreign matter, the other two contacts can still maintain signal transmission, thereby ensuring the conductivity of the signal. Since the possibility of foreign matter affecting the contact points is reduced, the design can significantly reduce the failure rate of the connector due to poor contact.

[0036] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0037] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0039] Embodiment 1 of the utility model of a three-contact connector compatible with different terminal pins

[0040] Please refer to Figure 1 The utility model discloses a three-contact connector compatible with different terminal pins, comprising: a plurality of terminal structures 1, wherein the terminal structure 1 comprises a terminal body 101, a lower clamp arm 104 is connected to one side of the terminal body 101, an auxiliary clamp arm 105 is fixedly connected to the top of the lower clamp arm 104, a third contact 108 is arranged on the top of the auxiliary clamp arm 105, a first contact 106 and a second contact 107 are also arranged on the top of the lower clamp arm 104, and the arrangement of the first contact 106, the second contact 107 and the third contact 108 makes the terminal structure 1 provided in the present application have three contacts. Compared with the traditional single-point contact design, the design of three contacts enables the connector to maintain a more stable contact state when affected by external force or environmental factors, thereby reducing the occurrence of poor contact; even if one of the contacts is affected by foreign matter, the other two contacts can still maintain signal transmission, thereby ensuring the conductivity of the signal. Since the possibility of foreign matter affecting the contact point is reduced, the present design can significantly reduce the failure rate of the connector caused by poor contact.

[0041] Further, such as Figure 1As shown, the lower clamp arm 104 is bent and the auxiliary clamp arm 105 is inclined. The bending of the lower clamp arm 104 and the inclination of the auxiliary clamp arm 105 cause the lower clamp arm 104 and the auxiliary clamp arm 105 to deform and generate a clamping force when the gold finger is inserted between the lower clamp arm 104, the auxiliary clamp arm 105 and the upper clamp arm 103, which can improve the firmness of the connection between the gold finger and the terminal structure 1, and can also maintain the connection between the gold finger and the first contact 106, the second contact 107 and the third contact 108.

[0042] Further, such as Figure 1 As shown, the side of the terminal body 101 close to the lower clamp arm 104 is fixedly connected to the upper clamp arm 103 located above the lower clamp arm 104, and the side of the terminal body 101 away from the lower clamp arm 104 is fixedly connected to the welding foot 102. The upper clamp arm 103 can cooperate with the lower clamp arm 104 and the auxiliary clamp arm 105 to clamp the gold finger.

[0043] Further, such as Figure 1 As shown, a positioning protrusion 109 is provided on the top of the terminal body 101 , and the positioning protrusion 109 is used for positioning the terminal body 101 during installation, so as to improve the uniformity of several terminal structures 1 after installation.

[0044] Embodiment 2 of the utility model of a three-contact connector compatible with different terminal pins

[0045] The utility model is further compatible with the three-contact connector of different terminal pins, such as Figure 2-Figure 4 As shown, a base structure 2 is arranged between several terminal structures 1, and the base structure 2 includes a first side seat 201 and a second side seat 202. Several module bases 204 are detachably connected between the first side seat 201 and the second side seat 202, that is, the base structure 2 provided in the present application adopts a modular design, and the specifications of the base structure 2 can be adjusted by adjusting the number of module bases 204 to meet different usage requirements, reduce mold opening costs and improve combination flexibility.

[0046] Further, such as Figure 2-Figure 3 As shown, a plurality of mounting grooves 203 are provided on the module base 204, the first side seat 201 and the second side seat 202, the terminal structure 1 is arranged in the mounting groove 203, and one end of the welding foot 102 away from the terminal body 101 extends out from the module base 204, and the module base 204 is arranged for the installation of the terminal structure 1.

[0047] Further, such as Figure 2As shown, a plurality of sockets 206 are provided on the module base 204 and the side of the first side seat 201 close to the second side seat 202. The second side seat 202 and the side of the module base 204 close to the first side seat 201 are fixedly connected with an insertion rod 205. One end of the insertion rod 205 is pointed, and the insertion rod 205 is plugged into the inner wall of the socket 206. The non-main body diameter of the insertion rod 205 is 0.05 mm larger than the inner diameter of the socket 206, so that the insertion rod 205 and the socket 206 can form an interference fit after being plugged in, so that the two are tightly connected. When the conductive sheet 207 and the welding foot 102 are welded to the welding pad, the overall structure is stable.

[0048] Further, such as Figure 2 As shown, the bottom of the first side seat 201 and the bottom of the second side seat 202 are both provided with a conductive sheet 207 , and the conductive sheet 207 is used to conduct static electricity on the base structure 2 to reduce the interference of static electricity on the base structure 2 .

[0049] When in use, the required number of module bases 204 is selected, and then the insertion rods 205 and the insertion holes 206 are plugged together to assemble the whole, and then the welding feet 102 and the conductive sheets 207 are welded to the corresponding welding positions.

[0050] Embodiment 3 of the utility model of a three-contact connector compatible with different terminal pins

[0051] The utility model is further compatible with the three-contact connector of different terminal pins, such as Figure 5-Figure 7 As shown, a cover 3 is provided between the second side seat 202 and the first side seat 201 , and the cover 3 is rotatably connected between the second side seat 202 and the first side seat 201 .

[0052] Further, such as Figure 6-Figure 7 As shown, both sides of the cover 3 are fixedly connected with connecting shafts 301, and the sides where the second side seat 202 and the first side seat 201 are close to each other are provided with connecting holes 4, and the outer surface of the connecting shaft 301 is plugged into the inner wall of the connecting hole 4. After confirming the number of module bases 204, a cover 3 of corresponding length is selected, and then the two connecting shafts 301 are plugged into the connecting holes 4 to complete the installation of the connecting holes 4. Since the first side seat 201 and the second side seat 202 are movable before welding, the cover 3 is easy to disassemble and assemble.

[0053] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model.
