[0007] According to another exemplary embodiment of the present invention, the first length of the first electrical contact portion in the longitudinal direction is less than the second length of the second electrical contact portion in the longitudinal direction.

[0008] According to another exemplary embodiment of the present invention, a slot is defined between the pair of first elastic arms, the pair of second elastic arms and the base to allow the mating terminal to be inserted, wherein the first elastic arm has an inclined guiding feature in an insertion port at the front end of the slot for guiding the mating terminal to be inserted into the slot in the correct orientation.

[0009] According to another exemplary embodiment of the present invention, the first elastic arm further includes an end portion opposite to the base in the height direction, the inclined guide feature and the first electrical contact portion are formed on the end portion, the inclined guide feature extends backward from the front end of the end portion and inclined toward the base portion, and is connected to the front end of the first electrical contact portion.

[0010] According to another exemplary embodiment of the present invention, the base includes a bottom wall and a tongue-shaped portion extending rearward and upward obliquely from the bottom wall, at least a portion of the tongue-shaped portion being opposite to the second electrical contact portion in the height direction, and in the lateral direction, the tongue-shaped portion being located in the middle of the base, and the first electrical contact portions of the pair of first elastic arms being located on both sides of the tongue-shaped portion.

[0011] According to another exemplary embodiment of the present invention, the tongue-shaped portion includes: a main body portion adapted to cooperate with the second elastic arm to clamp the mating terminal inserted into the connecting terminal, and adapted to engage with the mating terminal to lock the mating terminal; and an unlocking portion formed by bending upward from the rear end of the main body portion. The connecting terminal further includes a tongue-shaped portion reinforcing rib, the tongue-shaped portion reinforcing rib being formed protrudingly on the inner or outer surface of the tongue-shaped portion and extending from the main body portion to the unlocking portion.

[0012] According to another exemplary embodiment of the present invention, the connecting terminal further includes: a front reinforcing rib, which is protrudingly formed on the inner or outer surface of the base and disposed in front of the connection portion between the bottom wall and the tongue-shaped portion or the connection portion.

[0013] According to another exemplary embodiment of the present invention, the connecting terminal further includes: a first reinforcing rib, which is protrudingly formed on the inner or outer surface of the first elastic arm and extends toward the free end of the first elastic arm and the base, respectively.

[0014] According to another exemplary embodiment of the present invention, the connecting terminal further includes: a second reinforcing rib, which is protrudingly formed on the inner or outer surface of the second elastic arm and extends toward the free end of the second elastic arm and the base, respectively.

[0015] According to another exemplary embodiment of the present invention, the connecting terminal further includes: a cable connecting portion located at the rear end of the connecting terminal and adapted to be fixedly and electrically connected to a cable; a transition portion connected between the base and the cable connecting portion; and an intermediate reinforcing rib protrudingly formed on the inner or outer surface of the transition portion and extending toward the base and the cable connecting portion, respectively.

The multiple pairs of elastic arms provide multiple electrical contacts staggered in the transverse and longitudinal directions. When the mating terminal is inserted into the connecting terminal longitudinally, the mating terminal gradually contacts the multiple electrical contacts in the longitudinal direction, thereby further reducing the insertion force. Furthermore, the multiple electrical contacts contacting the mating terminal at different positions in the transverse and longitudinal directions ensures stable and reliable electrical contact with the mating terminal, improving the current-carrying capacity of the connecting terminal. Additionally, a pair of first elastic arms can guide the mating terminal to be inserted at the correct angle between a pair of second elastic arms and the base, and even if the mating terminal is not inserted correctly, causing deformation or even breakage of the first elastic arms, the second elastic arms can still ensure reliable electrical contact with the mating terminal.

Detailed Implementation

[0023] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of this utility model with reference to the accompanying drawings is intended to explain the overall concept of this utility model and should not be construed as a limitation thereof.

[0024] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0025] According to a general technical concept of the present invention, a connecting terminal is provided. The connecting terminal includes: a base; a pair of first elastic arms respectively connected to opposite sides of the base in a laterally oriented direction, and each including a first electrical contact portion adapted to make electrical contact with a mating terminal inserted between the base and the pair of first elastic arms; and a pair of second elastic arms respectively connected to the opposite sides of the base in a laterally oriented direction, and each including a second electrical contact portion adapted to make electrical contact with the mating terminal inserted between the base and the pair of second elastic arms. The pair of first elastic arms are located at the front end in a longitudinal direction of the connecting terminal and are spaced apart from the pair of second elastic arms in the longitudinal direction. In the lateral direction, the first electrical contacts of the pair of first elastic arms have a first distance, and the second electrical contacts of the pair of second elastic arms have a second distance, wherein the first distance is different from the second distance.

[0026] According to another general technical concept of the present invention, a connector is provided. The connector includes: a housing; and the aforementioned connecting terminals, which are inserted into the housing.

[0027] Figure 1 This is a perspective view of a connection terminal according to an exemplary embodiment of the present invention, taken from one viewpoint. Figure 2 show Figure 1A three-dimensional schematic diagram of the connection terminals viewed from another perspective; Figure 3 show Figure 1 A longitudinal sectional view of the connecting terminals in the middle; Figure 4 show Figure 3 A magnified view of point A in the image; Figure 5 show Figure 1 Front view of the connecting terminals.

[0028] like Figures 1 to 5 As shown, in an exemplary embodiment of this utility model, a connecting terminal is disclosed. The connecting terminal mainly includes a base 3, a pair of first elastic arms 1, and a pair of second elastic arms 2. The pair of first elastic arms 1 are respectively connected to opposite sides on the transverse X direction of the base 3, and each includes a first electrical contact portion 11 adapted to make electrical contact with a mating terminal (not shown) inserted between the base 3 and the pair of first elastic arms 1. The pair of second elastic arms 2 are respectively connected to opposite sides on the transverse X direction of the base 3, and each includes a second electrical contact portion 21 adapted to make electrical contact with a mating terminal inserted between the base 3 and the pair of second elastic arms 2. The pair of first elastic arms 1 are located at the front end on the longitudinal Y direction of the connecting terminal and are spaced apart from the pair of second elastic arms 2 on the longitudinal Y direction. On the transverse X direction, there is a first distance D1 between the first electrical contact portions 11 of the pair of first elastic arms 1, and a second distance D2 between the second electrical contact portions 21 of the pair of second elastic arms 2, wherein the first distance D1 is different from the second distance D2.

[0029] This connector terminal, by providing multiple pairs of elastic arms along the longitudinal direction Y, reduces the stiffness of each pair of elastic arms, thereby reducing the contact pressure applied to the mating terminal and thus reducing the insertion force. The multiple pairs of elastic arms provide multiple electrical contacts staggered in the transverse direction X and longitudinal direction Y. When the mating terminal is inserted into the connector terminal along the longitudinal direction Y, the mating terminal gradually contacts the multiple electrical contacts in the longitudinal direction Y, further reducing the insertion force. Furthermore, the different positions of the multiple electrical contacts in the transverse direction X and longitudinal direction Y ensure stable and reliable electrical contact with the mating terminal, improving the current-carrying capacity of the connector terminal. Additionally, a pair of first elastic arms 1 guides the mating terminal to be inserted at the correct angle between the base 3 and a pair of second elastic arms 2, and even if the mating terminal is not inserted correctly, causing deformation or even breakage of the first elastic arms 1, the second elastic arms 2 still ensure reliable electrical contact with the mating terminal.

[0030] In the illustrated embodiment, the connecting terminal includes two pairs of elastic arms spaced apart in the longitudinal Y direction. However, the present invention is not limited to the illustrated embodiment. For example, three or more pairs of elastic arms may also be spaced apart in the longitudinal Y direction.

[0031] like Figures 1 to 5As shown in the illustrated embodiment, the first distance D1 is greater than the second distance D2. Therefore, when the pair of first elastic arms 1 contact the mating terminals at their ends closer to the mating terminals in the lateral direction, they can effectively guide and limit the mating terminals, ensuring stable and accurate insertion into the connecting terminals.

[0032] like Figures 1 to 5 As shown in the illustrated embodiment, in the height direction Z, the third distance H1 from the first electrical contact 11 to the base 3 is greater than the fourth distance H2 from the second electrical contact 21 to the base 3. Therefore, the contact pressure applied by the first elastic arm 1 to the mating terminal is smaller, thereby reducing the overall contact pressure applied by the connecting terminal to the mating terminal and decreasing the insertion force.

[0033] like Figures 1 to 5 As shown in the illustrated embodiment, the first length L1 of the first electrical contact 11 in the longitudinal direction Y is less than the second length L2 of the second electrical contact 21 in the longitudinal direction Y. Therefore, the second electrical contact 21 has sufficient length so that even if the first elastic arm 1 fails, the second elastic arm 2 can still ensure reliable electrical contact with the mating terminal.

[0034] like Figures 1 to 5 As shown, in the illustrated embodiment, a slot 4 is defined between a pair of first resilient arms 1, a pair of second resilient arms 2, and a base 3, allowing mating terminals to be inserted. The first resilient arms 1 have an inclined guide feature 12 located in an insertion port at the front end of the slot 4 for guiding the mating terminals to be inserted into the slot 4 in the correct orientation.

[0035] like Figures 1 to 5 As shown in the illustrated embodiment, the first elastic arm 1 further includes an end portion 10 opposite to the base 3 in the height direction Z. An inclined guide feature 12 and a first electrical contact portion 11 are formed on the end portion 10. The inclined guide feature 12 extends backward from the front end of the end portion 10 and inclined toward the base 3, and is connected to the front end of the first electrical contact portion 11.

[0036] like Figures 1 to 5 As shown in the illustrated embodiment, the base 3 includes a bottom wall 31 and a tongue-shaped portion 32 extending rearward and upward at an angle from the bottom wall 31. At least a portion of the tongue-shaped portion 32 is opposite to the second electrical contact portion 21 in the height direction Z. In the transverse direction X, the tongue-shaped portion 32 is located in the middle of the base 3, and the first electrical contacts 11 of a pair of first elastic arms 1 are located on both sides of the tongue-shaped portion 32.

[0037] like Figures 1 to 5As shown, in the illustrated embodiment, the tongue-shaped portion 32 includes a main body portion 320 and an unlocking portion 321. The main body portion 320 is adapted to cooperate with the second elastic arm 2 to clamp the mating terminal inserted into the connecting terminal, and is adapted to engage with the mating terminal to lock the mating terminal. The unlocking portion 321 is formed by bending upward from the rear end of the main body portion 320. The connecting terminal also includes a tongue-shaped portion reinforcing rib 53, which is formed protrudingly on the outer surface of the tongue-shaped portion 32 and extends from the main body portion 320 to the unlocking portion 321. However, the present invention is not limited to the illustrated embodiment; for example, the tongue-shaped portion reinforcing rib 53 may also be formed protrudingly on the inner surface of the tongue-shaped portion 32.

[0038] like Figures 1 to 5 As shown in the illustrated embodiment, a locking feature 320a is formed on the main body 320. The locking feature 320a is adapted to engage with the mating terminal when the mating terminal is inserted into the slot 4 to lock the mating terminal in the slot 4. For example, the locking feature 320a protrudes upward from the tongue-shaped portion 32. When the mating terminal is inserted into the slot 4, the locking feature 320a is inserted into the locking hole of the mating terminal to lock the mating terminal in the slot 4. When it is necessary to remove the mating terminal from the slot 4, the locking feature 320a can be disengaged from the locking hole of the mating terminal by pressing the unlocking portion 321 downward toward the base 3 to release the lock.

[0039] like Figures 1 to 5 As shown in the illustrated embodiment, the connecting terminal further includes a front reinforcing rib 50. The front reinforcing rib 50 is formed protrudingly on the inner surface of the base 3 and is disposed at the connection point between the bottom wall 31 and the tongue-shaped portion 32 or in front of the connection point. However, the present invention is not limited to the illustrated embodiment; for example, the front reinforcing rib 50 may also be formed protrudingly on the outer surface of the base 3.

[0040] like Figures 1 to 5 As shown in the illustrated embodiment, the connecting terminal further includes a first reinforcing rib 51. The first reinforcing rib 51 protrudes from the outer surface of the first elastic arm 1 and extends toward the free end and base 3 of the first elastic arm 1, respectively. However, the present invention is not limited to the illustrated embodiment; for example, the first reinforcing rib 51 may also protrude from the inner surface of the first elastic arm 1.

[0041] like Figures 1 to 5 As shown in the illustrated embodiment, the connecting terminal further includes a second reinforcing rib 52. The second reinforcing rib 52 protrudes from the outer surface of the second elastic arm 2 and extends toward the free end and base 3 of the second elastic arm 2, respectively. However, the present invention is not limited to the illustrated embodiment; for example, the second reinforcing rib 52 may also protrude from the inner surface of the second elastic arm 2.

[0042] like Figures 1 to 5As shown in the illustrated embodiment, the connecting terminal further includes a cable connection portion 7, a transition portion 8, and an intermediate reinforcing rib 54. The cable connection portion 7 is located at the rear end of the connecting terminal and is adapted to be fixed and electrically connected to a cable. The transition portion 8 connects the base 3 and the cable connection portion 7. The intermediate reinforcing rib 54 is formed protrudingly on the outer surface of the transition portion 8 and extends toward both the base 3 and the cable connection portion 7. However, the present invention is not limited to the illustrated embodiment; for example, the intermediate reinforcing rib 54 may also be formed protrudingly on the inner surface of the transition portion 8.

[0043] By setting front reinforcing rib 50, first reinforcing rib 51, second reinforcing rib 52, tongue-shaped reinforcing rib 53 and middle reinforcing rib 54, the strength of the corresponding parts of the connecting terminal can be improved, so that thinner materials can be used to manufacture the connecting terminal to reduce costs while ensuring that the connecting terminal has sufficient strength.

[0044] like Figures 1 to 5 As shown in the illustrated embodiment, the first elastic arm 1 and the second elastic arm 2 are respectively connected to the base 3 via opposite sidewalls 6 on the transverse X of the connecting terminal, and are bent upward and inward from the sidewalls 6 to form a hook shape. However, the present invention is not limited to the illustrated embodiment. For example, the first elastic arm 1 and / or the second elastic arm 2 may also be directly connected to the base 3 and bent upward and inward from the base 3 to form a hook shape, or the first elastic arm 1 and / or the second elastic arm 2 may also be formed in other shapes.

[0045] like Figures 1 to 5 As shown in the illustrated embodiment, the connecting terminal is a one-piece stamped part, which can reduce manufacturing costs and improve manufacturing efficiency.

[0046] Although not illustrated, another exemplary embodiment of the present invention also discloses a connector. The connector includes a housing and the aforementioned connecting terminals, which are inserted into the housing.

[0047] According to an exemplary embodiment of the present invention, the connector further includes a cable electrically connected to the cable connection portion 7 of the connection terminal and led out from the housing.
