Next, with reference to the drawings, a terminal 100 according to an embodiment of the present utility model is described.

As shown in fig. 1 and 2, the terminal 100 includes a main body 1, the main body 1 including a mating portion 11, the mating portion 11 having a resilient arm 111 and a stopper 112, the resilient arm 111 being adapted to be in electrical contact with the first connector 101; with the engagement of the first connection member 101 with the elastic arm 111, the first connection member 101 pushes the elastic arm 111 to deflect the elastic arm 111 to provide the insertion space for the first connection member 101, while the elastic arm 111 is deformed, the elastic arm 111 has a tendency to return to the original shape to apply a force to the first connection member 101 so as to be in electrical contact with the first connection member 101 at the contact portion 1113, so that the contact portion 1113 presses the first connection member 101 to achieve reliable electrical connection of the terminal 100 and the first connection member 101.

Wherein the stopper 112 is configured to: the contact portion 1113 and the first connector 101 are in electrical contact, the abutting piece 112 directly or indirectly applies a force towards the first connector 101 to the corresponding elastic arm 111, and the abutting piece 112 applies a force towards the first connector 101 to the elastic arm 111 so as to increase the contact force between the contact portion 1113 and the first connector 101, thereby being beneficial to increasing the friction force between the contact portion 1113 and the first connector 101, improving the reliability of the electrical contact between the contact portion 1113 and the first connector 101, reducing the risk of the first connector 101 falling out from the insertion cavity 11a, ensuring stable fit between the first connector 101 and the terminal 100, and further ensuring the reliability and stability of the electrical connection between the terminal 100 and the first connector 101.

When the terminal 100 is used in an electrical connector, the electrical connector can be ensured to be suitable for complex working conditions and complex use environments (such as high-frequency vibration, cold and hot environments, high-dust and high-humidity environments, etc.), and still ensure the reliability and stability of electrical connection of the electrical connector.

As shown in fig. 1 and 2, the stopper 112 includes a first stopper 1121 and a second stopper 1122, the first stopper 1121 being configured to: when the contact portion 1113 is in electrical contact with the first connector 101, the first stopper 1121 directly or indirectly applies a force toward the first connector 101 to the corresponding elastic arm 111; the second stopper 1122 is configured to: when the elastic arms 111 are in electrical contact with the first connector 102, the second stop 1122 directly or indirectly applies a force to the corresponding elastic arms 111 toward the first connector 101.

While the elastic arm 111 has a first area and a second area, at least a portion of the first stop 1121 is adapted to overlap the first area, at least a portion of the second stop 1122 is adapted to overlap the second area, when the elastic arm 111 is in electrical contact with the first connector 101, the first stop 1121 is adapted to apply a force to the first area to bring the elastic arm 111 close to the first connector 101, and the second stop 1122 is adapted to apply a force to the second area to bring the elastic arm 111 close to the first connector 101.

It will be appreciated that the first stop 1121 is adapted to be in point contact, or line contact, or surface contact with a first region, and the second stop 1122 is adapted to be in point contact, or line contact, or surface contact with a second region.

It can be seen that the first stopper 1121 and the second stopper 1122 of the same stopper 112 may apply a force to the same elastic arm 111, and the positions where the first stopper 1121 and the second stopper 112 apply a force to the elastic arm 111 are different. So as to effectively promote the contact pressure between the elastic arm 111 and the first connecting piece 101 when the elastic arm 111 is in electrical contact with the first connecting piece 101, and ensure the reliability and stability of the electrical connection between the elastic arm 111 and the first connecting piece 101.

It will be appreciated that when the elastic arm 111 is not electrically connected to the first connector 101, the first abutment 1121 may directly or indirectly apply a force to the elastic arm 111, so that the elastic arm 111 has a tendency to deflect towards the position where the first connector 101 electrically connected to the elastic arm 111 is located, so that when the elastic arm 111 is electrically contacted to the first connector 101, the first abutment 1121 may provide a larger force, and the electrical connection is ensured to be reliable and stable; alternatively, when the elastic arm 111 is not electrically connected to the first connector 101, the first stopping member 1121 may be disposed at a distance from or in contact with the elastic arm 111, where the first stopping member 1121 may not apply a force to the elastic arm 111, and when the elastic arm 111 is electrically connected to the first connector 101, the first stopping member 1121 applies a force to the elastic arm 111 to ensure a reliable connection between the elastic arm 111 and the first connector 101.

In short, the first stop 1121 may directly or indirectly apply a force to the elastic arm 111 at any time to increase the contact pressure between the elastic arm 111 and the first connector 101 during the whole process that the first connector 101 starts pushing the elastic arm 111 to deform the elastic arm 111 until the first connector 101 makes electrical contact with the elastic arm 111.

Similarly, when the elastic arm 111 is not electrically connected to the first connector 101, the second abutting element 1122 can directly or indirectly apply a force to the elastic arm 111, so that the elastic arm 111 has a tendency to deflect towards the position where the first connector 101 electrically connected to the elastic arm 111 is located, so that when the elastic arm 111 is electrically contacted to the first connector 101, the second abutting element 1122 can provide a larger force, and the electrical connection is ensured to be reliable and stable; alternatively, when the contact portion 1113 is not electrically connected to the first connector 101, the second stopper 1122 may be spaced apart from or in contact with the elastic arm 111, where the second stopper 1122 may not apply a force to the elastic arm 111, and when the elastic arm 111 is electrically connected to the first connector 101, the second stopper 1122 applies a force to the elastic arm 111 to ensure reliable connection between the elastic arm 111 and the first connector 101.

In short, the second stopper 1122 may directly or indirectly exert a force on the elastic arm 111 at any time during the whole process that the first connector 101 starts pushing the elastic arm 111 to deform the elastic arm 111 until the first connector 101 makes electrical contact with the elastic arm 111, so as to increase the contact pressure between the elastic arm 111 and the first connector 101.

In the whole process that the first connector 101 starts to push the elastic arm 111 to deform the elastic arm 111 until the first connector 101 and the elastic arm 111 are in electrical contact, the moment when the first stopper 1121 applies the force to the elastic arm 111 is the same as or different from the moment when the second stopper 1122 applies the force to the elastic arm 111, and the sequence of the moment when the first stopper 1121 and the second stopper 1122 apply the force to the elastic arm 111 is not particularly limited. According to the terminal 100 of the embodiment of the utility model, the first abutting piece 1121 and the second abutting piece 1122 exert an acting force on the elastic arm 111 so as to increase the elastic contact force between the contact part 1113 and the first connecting piece 101 when the elastic arm 111 is electrically connected with the first connecting piece 101, thereby improving the stability and reliability of the electrical contact between the first connecting piece 101 and the contact part 1113, ensuring the stable and reliable electrical connection between the first connecting piece 101 and the terminal 100, enabling the terminal 100 to be suitable for complex working conditions and complex use environments, and improving the applicability and applicability of the terminal 100; when the terminal 100 is used in an electrical connector, reliability and stability of the electrical connection of the electrical connector under complex operating conditions can be ensured.

In some embodiments, as shown in fig. 2, the first area and the second area are sequentially arranged along the length direction of the elastic arm 111, and then the first abutment 1121 and the second abutment 1122 are sequentially arranged along the length direction of the elastic arm 111, so that the first abutment 1121 and the second abutment 1122 have enough arrangement space, and meanwhile, the overlapping area of the first abutment 1121 and the first area and the overlapping area of the second abutment 1122 and the second area are facilitated to be lifted, so that the reliable acting force exerted by the abutment 112 on the elastic arm 111 is ensured.

Of course, in other embodiments of the present application, the first area and the second area may also be disposed sequentially along the width direction of the elastic arm 111, and it may also be ensured that the abutment 112 applies a reliable force to the elastic arm 111. In some embodiments, as shown in fig. 2, at least one of the first and second abutments 1121, 1122 is configured to: the contact portion 1113 is spaced from the elastic arm 111 when separated from the first connector 101, so as to simplify the processing of the terminal 100, which may include the following aspects: 1. the first stopper 1121 is spaced apart from the elastic arm 111 when the contact portion 1113 is separated from the first connector 101; 2. the second stopper 1122 is spaced apart from the elastic arm 111 when the contact portion 1113 is separated from the first connector 101; 3. the first stopper 1121 and the second stopper 1122 are provided at intervals from the elastic arm 111 when the contact portion 1113 is separated from the first connector 101.

For example, when the contact portion 1113 is separated from the first connector 101, the first stopper 1121 and the second stopper 1122 are spaced from the elastic arm 111, so that a certain distance is reserved between the first stopper 1121 and the second stopper 1122 and the elastic arm 111, and at this time, the elastic arm 111, the first stopper 1121 and the second stopper 1122 may be in a natural state; in the process of inserting the first connector 101 into the inserting cavity 11a, after the first connector 101 pushes the contact portion 1113 to deform the elastic arm 111 by a certain amount, the first stop member 1121 and the second stop member 1122 cooperate with the elastic arm 111 to apply a force to the elastic arm 111, which is beneficial to ensuring that the first connector 101 receives a resistance with a proper size in the process of inserting the first connector 101 into the inserting cavity 11a and ensuring the installation feel of the first connector 101.

Of course, the arrangement of the stopper 112 is not limited thereto; in other embodiments, the first and second abutments 1121 and 1122 are each configured to: when the contact portion 1113 is separated from the first connector 101, the first stopper 1121 and the second stopper 1122 are respectively provided in contact with the elastic arm 111,

The cavity wall of the insertion cavity 11a is provided with an elastic arm 111 and an abutting piece 112, the elastic arm 111 and the abutting piece 112 are both located in the insertion cavity 11a, the insertion cavity 11a can protect the elastic arm 111 and the abutting piece 112 to a certain extent, and the use reliability of the elastic arm 111 and the abutting piece 112 is facilitated to be improved.

In some embodiments, as shown in fig. 1-3, the resilient arm 111 is cantilevered, and the resilient arm 111 has a first fixed end 1111 and a first free end 1112; the first fixed end 1111 is disposed near the mating opening 11b with respect to the first free end 1112, and then the first fixed end 1111 is located between the mating opening 11b and the first free end 1112 in the longitudinal direction of the mating portion 11 (or the longitudinal direction of the elastic arm 111), and the elastic arm 111 may play a certain guiding role for the mounting of the first connector 111. In the example of fig. 2, along the mating direction of the first connector 101 (for example, the direction from front to back in fig. 2), the mating space formed between the side wall of the mating cavity 11a opposite to the elastic arm 111 and the elastic arm 111 is gradually reduced, so that the elastic arm 111 can guide the first connector 101 to be quickly mated with the mating cavity 11a, and quick and accurate mating between the first connector 101 and the mating cavity 11a is ensured.

In other embodiments, the first free end 1112 is disposed near the mating opening 11b relative to the first fixed end 1111, i.e. the first fixed end 1111 is disposed far from the mating opening 11b relative to the first free end 1112, so that the first free end 1112 is located between the mating opening 11b and the first fixed end 1111 along the length direction of the mating portion 11, and the first connector 101 can be smoothly mated with the mating cavity 11a to be electrically connected with the elastic arm 111.

It can be appreciated that, when the first fixed end 1111 is disposed close to the mating opening 11b relative to the first free end 1112, the guiding portion 113 shields at least a portion of the first fixed end 1111 to avoid damage between the first connecting member 101 and the first fixed end 1111 when the first connecting member 101 is mated with the mating cavity 11 a; when the first free end 1122 is disposed near the mating opening 11b relative to the first fixed end 1111, the guiding portion 113 shields at least a portion of the first free end 1122 to prevent damage between the first connector 101 and the first free end 1122 when the first connector 101 is mated with the mating cavity 11 a.

In some embodiments, as shown in fig. 2, the guide portion 113 extends in a direction perpendicular to the axial direction of the insertion port 11b, so that the guide portion 113 is simple in structure and convenient to process.

In other embodiments, in the direction perpendicular to the axial direction of the mating opening 11b, the guiding portion 113 is disposed obliquely toward the elastic arm 111, so that the guiding portion 113 can properly reduce the opening size of the mating opening 11b, which is convenient for the mating opening 11b to guide the first connector 101 to be mated with the mating cavity 11a through the mating opening 11b, and is convenient for the user to operate.

The guide portion 113 is inclined toward the elastic arm 111, for example, the guide portion 113 is inclined toward the elastic arm 111 in a straight line shape, or the guide portion 113 is inclined toward the elastic arm 111 in a curved shape.

In some embodiments, as shown in fig. 1, the plurality of cavity walls of the mating cavity 11a include an upper cavity wall 13, a lower cavity wall 14, a first side cavity wall 15 and a second side cavity wall 16, the first side cavity wall 15 and the second side cavity wall 16 are respectively disposed on opposite sides (e.g., left and right sides in fig. 1) of the lower cavity wall 14, the upper cavity wall 13 includes a first top wall 131 and a second top wall 132, the first top wall 131 is disposed on a side (e.g., upper side in fig. 1) of the second top wall 132 facing away from the lower cavity wall 14, the first side cavity wall 15 is connected between the first top wall 131 and the lower cavity wall 14, the second side cavity wall 16 is connected between the second top wall 132 and the lower cavity wall 14, and the mating cavity 11a is formed among the second top wall 132, the first side cavity wall 15, the second side cavity wall 16 and the lower cavity wall 14; the stopping member 112 is disposed on the first top wall 131, and the elastic arm 111 is disposed on the second top wall 132. Thereby, the bending molding of the terminal 100 is facilitated.

In some embodiments, as shown in fig. 1-3, the elastic arm 111 is disposed in cantilever, and the elastic arm 111 has a first fixed end 1111 and a first free end 1122, and the elastic arm 111 further has a contact portion 1113, where the first area and the second area are located on two sides of the contact portion 1113 in the length direction of the elastic arm 111, respectively, so that the force applied by the first connector 101 to the elastic arm 111 is located between the force applied by the first stopper 1121 to the elastic arm 111 and the force applied by the second stopper 1122 to the elastic arm 111, so as to ensure that the elastic arm 111 bears enough pressing force to be stably located in a position where the elastic arm 111 is matched with the first connector 101, and further ensure that the elastic arm 111 is matched with the first connector 101 stably.

For example, as shown in fig. 2, one of the first area and the second area is located on a side (e.g., a front side in fig. 2) of the contact portion 1113 away from the first free end 1112, and the other of the first area and the second area is located on a side (e.g., a rear side in fig. 2) of the contact portion 1113 away from the first fixed end 1111, so that the force applied by the first stopping member 1121 to the elastic arm 111 and the force applied by the second stopping member 1122 to the elastic arm 111 may be located on two sides of the force applied by the first connecting member 101 to the elastic arm 111, respectively, so as to ensure that the elastic arm 111 is stressed more uniformly in the mating cavity 11a, and has good stability, which is beneficial to avoid the tendency of the elastic arm 111 to deflect relative to the first fixed end 1111 under the actions of the stopping member 112 and the first connecting member 101, so as to reduce the bearing capacity at the first fixed end 1111, so as to ensure that the elastic arm 111 is reliably set.

In other embodiments of the present application, the first region and the second region may also be both located on the same side of the contact portion 1113 in the length direction of the elastic arm 111, and the first region and the second region may be sequentially arranged in the width direction of the elastic arm 111; at this time, the first stopper 1121 and the second stopper 1122 may be sequentially arranged in the width direction of the elastic arm 111, and the first stopper 1121 and the second stopper 1122 may be provided on the same side wall or the opposite side wall of the mating portion 11.

In some embodiments, as shown in fig. 2, the first stopping element 1121 and the second stopping element 1122 are disposed at intervals along the length direction of the elastic arm 111, where, with respect to the contact portion 1113, the first stopping element 1121 may be located at a side where the first area is located, and the second stopping element 1122 may be located at a side where the second area is located, so that the reaction force applied by the elastic arm 111 to the first stopping element 1121 does not affect the deformation of the second stopping element 1122, and the reaction force applied by the elastic arm 111 to the second stopping element 1122 does not affect the deformation of the first stopping element 1121, so as to ensure that the forces applied by the first stopping element 1121 and the second stopping element 1122 to the elastic arm 111 towards the first connecting element 101 are balanced, and improve the electrical connection stability between the first connecting element 101 and the contact portion 1113.

Of course, the first stopper 1121 may be located on the side of the second region with respect to the contact portion 1113, and the second stopper 1122 may be located on the side of the first region, and the first stopper 1121 and the second stopper 1122 may be disposed to intersect.

In some embodiments, as shown in fig. 1 and 2, the first stopping member 1121 is disposed in cantilever, and the first stopping member 1121 has a second fixed end and a second free end, the second fixed end is located outside the first fixed end 1111, the second free end is located on a side of the contact portion 1113 (e.g., a front side in fig. 2) away from the first free end 1112, and then the entire first stopping member 1121 is located on a side of the contact portion 1113 away from the first free end 1112, so as to simplify the structure of the first stopping member 1121.

In addition, the first stopping member 1121 is provided in a cantilever manner, so that the first stopping member 1121 has good deformability, so that when the first connecting member 101 is installed, an installation resistance with a proper size can be applied to the first connecting member 101 through the elastic arm 111, and when the first connecting member 101 is installed in place, an elastic extrusion force with a proper size can be applied to the first connecting member 101 through the elastic arm 111, so that the installation hand feeling of the first connecting member 101 is improved on the premise of ensuring that the first connecting member 101 is reliably connected with the elastic arm 111.

In the description of the present application, the direction "outer" is understood as the direction away from the mating cavity 11a in the cross section of the mating cavity 11a, and the opposite direction is "inner".

In some embodiments, as shown in fig. 1 and 2, the second stopping member 1122 is disposed in cantilever, and the second stopping member 1122 has a third fixed end and a third free end, the third fixed end is located outside the first free end 1112, the third free end is located on one side (e.g., the rear side in fig. 2) of the contact portion 1113 away from the first fixed end 1111, and then the whole second stopping member 1122 is located on one side of the contact portion 1113 away from the first fixed end 1111, so as to simplify the structure of the second stopping member 1122.

In addition, the second abutting piece 1122 is arranged in a cantilever manner, so that the second abutting piece 1122 has good deformability, and therefore when the first connecting piece 101 is installed, the elastic arm 111 can apply an installation resistance with a proper size to the first connecting piece 101, and when the first connecting piece 101 is installed in place, the elastic arm 111 can apply an elastic extrusion force with a proper size to the first connecting piece 101, so that the installation hand feeling of the first connecting piece 101 is improved on the premise of ensuring that the first connecting piece 101 is reliably connected with the elastic arm 111.

In some embodiments, as shown in fig. 1 and 2, the first stopper 1121 is cantilevered and has a second fixed end and a second free end, the second fixed end is located outside the first fixed end 1111, the second free end is located on a side of the contact portion 1113 away from the first free end 1112, the second stopper 1122 is cantilevered and has a third fixed end and a third free end, the third fixed end is located outside the first free end 1112, and the third free end is located on a side of the contact portion 1113 away from the first fixed end 1111.

In some embodiments, as shown in fig. 2, the elastic arm 111 includes a first elastic segment 1114 and a second elastic segment 1115, the contact portion 1113 is located at a connection position of the first elastic segment 1114 and the second elastic segment 1115, the first elastic segment 1114 extends inward from the first fixed end 1111, and the second elastic segment 1115 extends outward from one end of the first elastic segment 1114, so that the elastic arm 111 forms a structure similar to a V shape, which facilitates forming the contact portion 1113 as a rounded transition portion, so as to avoid the contact portion 1113 from scratching a plating layer of the first connector 101 during the assembly process of the contact portion 1113 and the first connector 101.

Wherein, the first elastic segment 1114 is adapted to be attached to the first stopping member 1121, and then the first elastic segment 1114 is adapted to be in surface contact with the first stopping member 1121, and the second elastic segment 1115 is adapted to be attached to the second stopping member 1122, and then the second elastic segment 1115 is adapted to be in surface contact with the second stopping member 1122, and the second elastic segment 1115 extends outwards, so that the second stopping member 1122 applies a force to the elastic arm 111 through the second elastic segment 1115, that is, the second elastic segment 1115 can provide a good force application position for the second stopping member 1112.

In the process of inserting the first connecting piece 101 into the insertion cavity 11a, the first abutting piece 1121 is in surface contact with the first elastic section 1114 to provide a force applied to the first elastic section 1114, and the second abutting piece 1122 is in surface contact with the second elastic section 1115 to provide a force applied to the second elastic section 1115, so that the acting area of the abutting piece 112 on the elastic arm 111 is conveniently increased, the stress of the elastic arm 111 is facilitated to be dispersed, the elastic capability of the elastic arm 111 is ensured, the electric connection of the contact portion 1113 and the first connecting piece 101 is ensured to be stable and reliable, and the first connecting piece 101 and the terminal 100 are prevented from being separated due to vibration and the like.

For example, in the example of fig. 2, when the first connector 101 is not mounted (the terminal 100 is in a natural state, as shown in fig. 2), the inclination direction of the first stopper 1121 and the inclination direction of the first elastic section 1114 are substantially parallel in order to ensure a contact area between the first stopper 1121 and the first elastic section 1114 during the mounting of the first connector 101; of course, the inclination direction of the first stopper 1121 and the inclination direction of the first elastic section 1114 may also be non-parallel in the natural state of the terminal 100.

Also, in the example of fig. 2, when the first connector 101 is not mounted, the inclination direction of the second stopper 1122 and the inclination direction of the second elastic section 1115 are substantially parallel so as to ensure a contact area between the second stopper 1122 and the second elastic section 1115 during the mounting of the first connector 101; of course, in the natural state of the terminal 100, the inclination direction of the second stopper 1122 and the inclination direction of the second elastic section 1115 may not be parallel.

In some embodiments, as shown in fig. 2, the length of the first elastic section 1114 is greater than the length of the second elastic section 1115, so that when the first fixed end 1111 is disposed close to the mating port 11b with respect to the first free end 1112, the first elastic section 1114 may form a longer guide path for guiding the first connector 101 to facilitate quick installation of the first connector 101; moreover, the elastic capability of the first elastic section 1114 is larger than that of the second elastic section 1115, so that the first elastic section 1114 has resistance with a proper size to the installation of the first connecting piece 101, the installation of the first connecting piece 101 is further facilitated, and the first connecting piece 101 can be clamped by the reaction force applied by the first elastic section 1114 to the first connecting piece 101, so that the first connecting piece 101 is not easy to break out of the plug-in matching cavity 11a, and the connection reliability of the first connecting piece 101 and the terminal 100 is ensured.

In some embodiments, as shown in fig. 2, the first stop 1121 has a length L1, the elastic arm 111 has a length L2, 30% L1/L2 80%, and the first stop 1121 provides sufficient force to the elastic arm 111 to enhance the elastic contact force of the contact portion 1113 with the first connector 101, maintaining the reliability and stability of the electrical connection of the terminal 100 with the first connector 101; it is also convenient to make the first stopper 1121 provide a resistance of an appropriate magnitude to the installation of the first connector 101 to ensure the installation feel and convenience of the first connector 101.

Alternatively, L1/L2 may be 30%, or 50%, or 75%, or 80%, etc.

Further, the L1/L2 is more than or equal to 50% and less than or equal to 80%; alternatively, L1/L2 may be 50%, or 65%, or 70%, or 80%, etc.
