Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus a repetitive description thereof will be omitted.

The words expressing the positions and directions described in the present utility model are described by taking the drawings as an example, but can be changed according to the needs, and all the changes are included in the protection scope of the present utility model.

As shown in fig. 1, a sleeve 100 of a terminal connector 300 according to an embodiment of the present utility model includes a body portion 2 and an elastic member 1 connected to each other.

The elastic member 1 may be integrally formed with the main body portion 2, and the elastic member 1 may be provided in plurality, and the plurality of elastic members 1 may be distributed on opposite sides of the main body portion 2 in a direction perpendicular to the insertion direction of the terminal 400, so that the plurality of elastic members 1 may abut against opposite sides of the terminal 400 to clamp the terminal 400; the elastic members 1 located at the same side of the main body 2 may be sequentially arranged, for example, the elastic members 1 located at the same side of the main body 2 may be arranged at equal intervals along the width direction thereof. The elastic member 1 is formed with a first side surface 14 on a side facing away from the terminal 400, and the elastic member 1 is provided with a plurality of contact portions protruding from the first side surface 14 toward the terminal 400, the contact portions being for elastically abutting against the terminal 400 to clamp the terminal 400. Moreover, the elastic modulus of one contact part can be larger than that of the other contact parts, so that the contact part with larger elastic modulus has larger clamping force than the other contact parts and is not easy to deform; if the terminal 400 vibrates, the elastic member 1 may rotate around the contact portion having a large elastic modulus to buffer the vibration of the terminal 400.

With further reference to fig. 2, in the present embodiment, the elastic member 1 may include a first contact portion 11, a second contact portion 12, and a third contact portion 13 protruding from the first side 14 toward the terminal 400, and the first contact portion 11, the second contact portion 12, and the third contact portion 13 are commonly used to sandwich the terminal 400. The first contact portion 11 may be disposed at a rear end of the elastic member 1 in the insertion direction of the terminal 400, the third contact portion 13 may be disposed at a front end of the elastic member 1 in the insertion direction of the terminal 400, and the second contact portion 12 may be disposed between the first contact portion 11 and the third contact portion 13, that is, during the insertion of the terminal 400, the terminal 400 is in contact with the first contact portion 11, the second contact portion 12, and the third contact portion 13 in this order.

The body 2 is formed with a receiving cavity 22, and the elastic member 1 extends from one side of the body 2 into the receiving cavity 22 along the insertion direction of the terminal 400. The main body 2 is also provided with a support portion 21 formed to protrude toward the elastic member 1. When the elastic member 1 is deformed by the terminal 400, the elastic member 1 deforms toward the supporting portion 21 and abuts against the supporting portion 21, so that the supporting portion 21 can support the elastic member 1, limit the deformation amplitude of the elastic member 1, and prevent the elastic member 1 from further deforming; the supporting force of the elastic member 1 generated when the supporting portion 21 supports the elastic member 1 can also be used to enhance the clamping effect of the elastic member 1 on the terminal 400.

Wherein the position of the support portion 21 may correspond to the position of the contact portion. Specifically, the projection of the support portion 21 formed on the elastic member 1 coincides with at least a portion of the contact portion, that is, at least a portion of the support portion 21 is located above the contact portion, so that the supporting force exerted by the support portion 21 on the elastic member 1 can act on the contact portion or a position adjacent to the contact portion. Since the elastic member 1 deforms by the relative force generated when the contact portion abuts against the terminal 400, the position of the supporting portion 21 is set to correspond to the position of the contact portion, the supporting effect of the supporting portion 21 on the elastic member 1 can be enhanced, excessive deformation of the elastic member 1 can be prevented more effectively, and the holding force applied to the terminal 400 by the contact portion can be increased.

The position of the support portion 21 may specifically correspond to the position of the first contact portion 11, i.e. the projection of the support portion 21 formed on the elastic member 1 coincides with at least part of the first contact portion 11.

In some embodiments, the supporting portion 21 may abut against a portion of the first side surface 14 adjacent to the outer periphery of the first contact portion 11, so as to avoid that after the supporting portion 21 directly abuts against the first contact portion 11, the elastic modulus of the first contact portion 11 is increased, so as to block the deformation of the first contact portion 11, and further affect the deformation of the elastic member 1. Specifically, the projection of the support portion 21 formed on the elastic member 1 partially coincides with the first contact portion 11, partially coincides with the first side surface 14, and the first contact portion 11 is farther from the support portion 21 than the first side surface 14. When the elastic member 1 deforms and abuts against the supporting portion 21, the supporting portion 21 abuts against a portion of the first side surface 14 adjacent to the outer periphery of the first contact portion 11, so as to apply a supporting force to the adjacent position of the first contact portion 11, thereby limiting the deformation range of the elastic member 1.

With further reference to fig. 3, in some embodiments, the first contact portion 11 may be a three-dimensional protrusion, and a length of at least a portion of a projection of the support portion 21 formed on the elastic member 1 in the first direction is greater than a length of the first contact portion 11 at a corresponding position in the first direction; that is, in the second direction perpendicular to the first direction, the length of the projection in the first direction at the same position is longer than the length of the first contact portion 11 in the first direction at that position, and the support portion 21 can bridge the recess formed in the first side surface 14 of the first contact portion 11 in the first direction, so that the portion of the support portion 21 beyond the first contact portion 11 at the corresponding position can abut against the portion of the first side surface 14 adjacent to the outer periphery of the first contact portion 11. The first direction may be a width direction of the elastic member 1, and the second direction may be a length direction of the elastic member 1. The length of the opposite ends of the support portion 21 in the second direction in the first direction may be greater than the length of the first contact portion 11 at the corresponding position in the first direction, and the length of the intermediate portion of the support portion 21 in the second direction in the first direction may be greater than or less than the length of the first contact portion 11 at the corresponding position in the first direction. And/or, a length of at least a portion of the projection of the support portion 21 formed on the elastic member 1 in the second direction is greater than a length of the first contact portion 11 at the corresponding position in the second direction. That is, the length of the projection of the support portion 21 located at the same position in the first direction in the second direction is longer than the length of the first contact portion 11 located at the same position in the second direction, and the support portion 21 may span the recess formed on the first side surface 14 by the first contact portion 11 in the second direction, so that the portion of the support portion 21 beyond the first contact portion 11 at the corresponding position may abut against the portion of the first side surface 14 adjacent to the outer periphery of the first contact portion 11. Wherein. The first contact portion 11 may specifically be a spherical structure integrally punched from the elastic member 1.

In still other embodiments, the first contact portion 11 may be an arch-shaped protrusion formed by integral bending. The length of the support portion 21 in the second direction is longer than the length of the first contact portion 11 in the second direction, so that a portion of the support portion 21 beyond the first contact portion 11 in the second direction can abut against a portion of the first side surface 14 adjacent to the outer periphery of the first contact portion 11.

In some embodiments, the elastic modulus of the first contact portion 11 may be greater than the elastic modulus of the second contact portion 12 and the third contact portion 13, so that the terminal 400 vibrates, and the elastic member 1 may rotate around the first contact portion 11. By providing the support portion 21 so as to correspond to the first contact portion 11 having a large elastic modulus, the rotational movement of the elastic member 1 around the first contact portion 11 is prevented from being affected by the increase in elastic modulus caused by the abutment of the other contact portion with the support portion 21.

In some embodiments, the support portion 21 and the elastic member 1 are separated from each other when the first contact portion 11 does not abut against the terminal 400; after the first contact portion 11 abuts against the terminal 400, the elastic member 1 is deformed toward the substrate 200 by the force of the terminal 400, and the support portion 21 abuts against the elastic member 1. Therefore, when the elastic member 1 is connected with the terminal 400, a gap for generating a certain deformation amount can be reserved between the supporting portion 21 and the elastic member 1, and then the elastic member 1 is abutted against the supporting portion 21, so that when the elastic member 1 is just abutted against the supporting portion 21, the clamping force on the terminal 400 is generated by each contact portion of the elastic member 1, and the situation that after the supporting portion 21 limits the deformation of the elastic member 1, the clamping force on the terminal 400 is insufficient by other contact portions of the elastic member 1 except the first contact portion 11 is avoided; moreover, when the terminal 400 is just connected with the sleeve 100, the gap between the supporting portion 21 and the elastic member 1 can facilitate the deformation of the elastic member 1 at this time, so as to facilitate the movement of the terminal 400 and further facilitate the installation between the terminal 400 and the terminal sleeve 100.

So that each elastic member 1 can be restrained by the supporting portion 21 to avoid excessive deformation. One support portion 21 may correspond to one elastic member 1 to limit the deformation amplitude of the one elastic member 1, or one support portion 21 may correspond to a plurality of elastic members 1 to limit the deformation amplitude of the plurality of elastic members 1.

With further reference to fig. 4, in some embodiments, a plurality of support portions 21 may be provided, and each elastic member 1 corresponds to at least one support portion 21. Specifically, the number of the supporting portions 21 is the same as the number of the elastic members 1 and corresponds to one another one by one, so that each supporting portion 21 is used to limit the deformation amplitude of one elastic member 1, and more specifically, the plurality of supporting portions 21 are disposed at intervals in the main body portion 2 and correspond to the first contact portions 11 of the elastic members 1 one by one.

With further reference to fig. 5, in still other embodiments, one support 21 may be used to support a plurality of elastic members 1 to limit the magnitude of deformation of the plurality of elastic members 1. Specifically, the support portion 21 is an integral support portion 21 extending in the arrangement direction of the elastic members 1 and corresponds to the plurality of first contact portions 11, and when the plurality of elastic members 1 extend in the width direction thereof, the support portion 21 extends in the width direction of the elastic members 1. Also, the supporting portion 21 may form projections on the plurality of elastic members 1, and the projections of the supporting portion 21 on the plurality of elastic members 1 and the plurality of first contact portions 11 are at least partially overlapped, so that one supporting portion 21 may simultaneously support the plurality of first contact portions 11 of the plurality of elastic members 1 to limit the deformation amplitude of the plurality of elastic members 1. Preferably, the support portion 21 is projected on the plurality of elastic members 1, partially overlapped with the plurality of first contact portions 11, partially overlapped with the first side surface 14 of the plurality of elastic members 1 adjacent to the outer peripheral portion of the first contact portions 11, so that the support portion 21 can abut against the first side surface 14 of the plurality of elastic members 1. By controlling the extension length of the support portion 21, one support portion 21 may correspond to two, three, or the like number of elastic pieces 1, and in this embodiment, one support portion 21 may correspond to a plurality of elastic pieces 1 located on the same side of the main body portion 2.

As shown in fig. 6, a terminal connector 300 according to the present utility model includes a substrate 200 and the sleeve 100 sleeved on the substrate 200, wherein an elastic member 1 of the sleeve 100 is accommodated in the substrate 200, and a main body 2 of the sleeve 100 is sleeved outside the substrate 200. The substrate 200 is provided with a receiving chamber 201 for receiving the terminal 400. The sleeve 100 is sleeved on the substrate 200, so that at least a part of the substrate 200 is accommodated in the accommodating cavity 22 formed by the terminal sleeve 100. The elastic member 1 in the sleeve 100 may extend into the accommodation chamber 201 in the insertion direction of the terminal 400 such that at least a portion of the substrate 200 is located between the body portion 2 and the elastic member 1. The main body 2 is provided with a support 21 penetrating the substrate 200 toward the elastic member 1.

With further reference to fig. 7 and 8, the supporting portion 21 is formed by recessing the surface of the main body portion 2 toward the direction of the substrate 200, and the supporting portion 21 protrudes from the inner surface of the substrate 200 and enters the accommodating chamber 201. To facilitate the coupling of the support portion 21 and the elastic member 1, the substrate 200 may be provided with a relief hole 202, where the relief hole 202 penetrates the substrate 200, and the dimension of the relief hole 202 is adapted to the support portion 21. When the base plate 200 is connected with the sleeve 100, at least a portion of the supporting portion 21 passes through the avoidance hole 202 of the base plate 200 and extends into the accommodating cavity 201, so that the elastic member 1 located in the accommodating cavity 201 can be abutted against the supporting portion 21 after being deformed, and the supporting portion 21 provides supporting force for the elastic member 1, so that the elastic member 1 is prevented from being excessively deformed, the clamping force of the elastic member 1 is increased, and the service life of the terminal connecting member 300 is prolonged. In addition, when the supporting portion 21 is disposed in the avoidance hole 202, the supporting portion 21 may cooperate with a sidewall forming the avoidance hole 202, so as to increase the binding force between the sleeve 100 and the substrate 200, so as to limit the relative movement between the substrate 200 and the sleeve 100, prevent the two from being separated, increase the reliability of electrical contact between the two, and also facilitate positioning the positions of the substrate 200 and the sleeve 100.
