Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, the use of directional terms such as "upper, lower, left, right" generally means upper, lower, left, right as viewed with reference to the accompanying drawings, unless otherwise specified; "inner and outer" refer to the inner and outer relative to the profile of the components themselves. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

According to an aspect of the present application, there is provided an electrical connector, wherein the electrical connector comprises:

a housing 10 having a socket 11 on a top surface for receiving a carrier;

a socket member 20, wherein the socket member 20 is movably mounted in the housing 10, the socket member 20 has a socket 21 capable of aligning and communicating with the socket 11, and a first contact 211 is disposed in the socket;

the lead 30 is arranged by penetrating the base 10 and is connected with the first contact 211;

a locking member 40, the locking member 40 rotatably penetrates the seat body 10 and always abuts against the slot member 20, the outer periphery of the locking member 40 abutting against the slot member 20 has a position with a distance different from the rotation axis of the locking member 40, the exposed portion of the locking member 40 exposed outside the seat body 10 can be operated to rotate the locking member 40 relative to the seat body 10, so that the slot member 20 is switched from an unlocking state in which the slot 21 is aligned with the socket 11 to a locking state in which the slot 21 is staggered with the socket 11, wherein in the locking state, the slot member 20 and the seat body 10 can be relatively fixed.

In the electrical connector of the present application, the locking member 40 is rotationally operated to drive the socket member 20 to complete the locking, i.e., the mounting of the carrier 60, without applying an additional force to the carrier 60, thereby preventing damage to the electrical components on the carrier 60 during mounting.

Specifically, in the unlocked state, the carrier 60 is placed into the socket 21 from the socket 11 such that the second contacts 61 on the carrier 60 contact the first contacts 211 in the socket 21. Subsequently, by operating the exposed portion to rotate the locking member 40, different peripheral positions of the locking member 40 can be abutted to the slot member 20, when the locking member 40 rotates from a position where the peripheral distance is closer to the rotation axis to a position farther away, the locking member 40 abuts to push the slot member 20 to move linearly relative to the seat body 10 to a locking state, and the slot member 20 can be kept relatively fixed with the seat body 10 in the locking state, so that the installation of the carrier 60 is completed. In this process, no additional manipulation or application of force to the carrier 60 is required, avoiding damage to the electrical components on the carrier 60.

Similarly, in the locked state, by releasing the relative fixation between the socket member 20 and the housing 10 and rotating the locking member 40 in the reverse direction, the socket member 20 can move in the reverse direction, thereby returning to the unlocked state. This process also avoids the need to work on the carrier 60 and avoids damage to the electrical components on the carrier 60.

The relative fixing of the socket member 20 to the holder body 10 in the locking state can be provided by the locking member 40 or by another structure. Further, the reverse movement of the socket member 20 from the locked state to the unlocked state may be triggered by the lock member 40 or by another structure.

For example, the lock member 40 may be used only for switching, when the rotation of the lock member 40 drives the slot member 20 to switch to the locked state, the slot member 20 may be held in the locked state by another limit structure, for example, the slot member 20 may be moved into a limit groove in which a groove bottom can be raised and lowered to be held in the locked state, when switching from the locked state to the unlocked state is required, the groove bottom of the limit groove may be operated to be lifted to a position where the slot member 20 can be separated, and the slot member 20 may be linked with the lock member 40 (for example, the lock member 40 may be provided with a shaft coinciding with a rotation axis thereof, the slot member 20 may be connected with a rope wound around the shaft of the lock member 40, so that the slot member 20 is pulled by withdrawing the rope when the lock member 40 rotates), so that the slot member 20 is moved to return to the unlocked state when the lock member 40 rotates in the reverse direction.

Preferably, the housing 10 has an accommodating chamber for inserting the locking member 40, one side of the accommodating chamber is open to allow the locking member 40 to contact the socket member 20, the locking member 40 includes a rod 41 inserted into the accommodating chamber, and an outer peripheral surface of the rod 41 has a pressing portion 411 (corresponding to a portion closer to the rotation axis of the locking member 40) for pressing and contacting the socket member 20 and a locking portion 412 (corresponding to a portion farther from the rotation axis of the locking member 40) for surface contacting the socket member 20. Specifically, when the lock member 40 is rotated in the unlocked state, the lock member 40 contacts the socket member 20 via the urging portion 41 to urge the socket member 20 to move to the locked state; in the locked state, the lock member 40 rotates to come into surface contact with the socket member 20 through the lock portion 412, thereby increasing the contact surface and the frictional force with the socket member 20, so that the socket member 20 is maintained in the locked state.

The pushing portion 411 may be in any suitable form, as long as it can provide pushing against the slot member 20 during rotation of the locking member 40. The pressing portion 411 is an elliptical surface, and the locking portion 412 is a flat surface. Thus, when the lock member 40 rotates from the unlocked state, the pressing portion 411 of the elliptical surface first contacts the socket member 20, and as the rotation proceeds, the contact position of the socket member 20 and the lock member 40 gradually separates from the rotation axis of the lock member 40 by the gradual expansion of the elliptical surface, so that the socket member 20 moves in a straight line to the locked state. When the locking state is reached, the locking member 40 rotates to enable the planar locking part 412 to be in surface contact with the slot member 20, so that the slot member 20 is kept in the locking state on one hand, and the rotation resistance between the locking part 412 and the slot member 20 is increased on the other hand, and the locking member 40 is prevented from rotating away from the locking state. For convenience of processing and fabrication, as shown in fig. 5, the rod body 41 is a rod with a uniform cross section, the cross section profile is substantially elliptical to form the pressing portion 411, and straight line segments are provided only at both ends of the major axis to form the locking portion 412.

In addition, in order to assist the locking state in which the locking portion 412 holds the socket member 20, it is preferable that a portion of the socket member 20 contacting the lever body 41 is provided with a recess 22. Thus, when the locked state is reached, the locking portion 412 enters the recess 22 and forms a snap fit, on the one hand, the slot member 20 is stably held in the locked state by the locking member 40, and on the other hand, a greater activating action is required to rotate the locking member 40, so that the locking member 40 is better prevented from being accidentally rotated. In order to avoid the locking portion 412 from being locked with the concave portion 22, the concave portion 22 is configured to be able to completely accommodate the locking portion 412, and the concave portion 22 may also be configured as an arc surface or an inclined surface.

In order to reset the socket member 20 from the locked state to the unlocked state, preferably, the electrical connector includes a reset member 50 mounted on the base 10, the reset member 50 and the locking member 40 respectively abut against two sides of the socket member 20, and the reset member 50 is configured to provide a reset force to the socket member 20 toward the unlocked state in the locked state. Therefore, when the unlocking is needed, the locking piece 40 is rotated reversely, the resetting force of the resetting piece 50 forces the slot piece 20 to abut against the locking piece 40 all the time and drives the plug piece 20 to drive the locking piece 40 to move reversely and reset.

The restoring member 50 may be in various suitable forms as long as it can abut the socket member 20 to provide the restoring force. To simplify the structure, the restoring member 50 includes a spring, as shown in fig. 3 and 6. To facilitate the installation of the spring, the housing 10 may be provided with a shaft portion 12, one end of the spring is fixed to the socket member 20, and the other end of the spring is wound around the shaft portion 12 and then fixed to the shaft portion 12. When the socket 20 is used, the spring can be in a free state in the unlocked state, and the spring is gradually compressed to accumulate the return elastic force in the process of moving the socket from the unlocked state to the locked state.

In order to ensure that the spring provides a linear force to the slot member 20 along a linear path from the unlocked state to the locked state, the holder body 10 may have a limiting cavity surrounding the shaft portion 12 to limit the spring to move only in the axial direction of the shaft portion 12. Wherein, the spacing cavity can be designed according to the specific form of the seat body 10. For example, when the base 10 is a separate structure of the base 14 and the top cover 15, which will be described below, the limiting cavity can be defined by the base 14 and the top cover 15 together.

In addition, in order to test electrical components on a plurality of carriers 60 simultaneously, a plurality of sockets 11 may be provided on the housing 10 and corresponding socket members 20 and locking members 40 may be installed. Preferably, as shown in fig. 1 to 4, the seat 10 has two sockets 11 symmetrically disposed about a width center line of the seat 10, the electrical connector has two slot members 20, a fixing seat 13 is disposed in a middle portion of the seat 10 in a width direction, two sides of the fixing seat 13 extend out of the shaft portion 12, and each shaft portion 12 is wound with the corresponding spring. In the illustrated embodiment, the mounting base 13 may be configured to provide support for the springs on both sides, and the locking member 40 and the socket member 20 on both sides may be independently operable.

In the present application, the housing 10 can be of various suitable forms, such as a single piece, and preferably, the housing 10 can be of a split structure for ease of maintenance and removal of components such as the socket member 20 located within the housing 10. Specifically, as shown in fig. 6, the base body 10 includes a base 14 and a top cover 15 detachably connected to each other, and the socket 11 is disposed on the top cover 15.

In addition, the carrier 60 may be fully inserted into the socket member 20 or mostly inserted into the socket member 20 in the present application. In contrast to the unlocked state, in the locked state, socket member 20 and carrier 60 received therein are moved relative to housing 10 such that socket 21 of socket member 20 is no longer aligned with socket 11 such that socket member 20 and carrier 60 therein are positioned within housing 10, and thus housing 10 can provide a stop for carrier 60 in socket member 20 from above. To facilitate access to the carrier 60, the carrier 60 may have a main body 62 for mounting electrical components (e.g. a non-implanted end) and a handle portion 63 projecting from the main body 62, the main body 62 may be fully received within the socket 21, and to facilitate placement of the projecting handle portion 63 when the socket member 20 is switched to the locked condition, as shown in fig. 1, the cover 15 may have a notch 16 extending from the socket 11 to align with a portion of the socket 21 in the locked condition. When the socket member 20 is switched from the unlocked state to the locked state, the handle portion 63 can be moved from the socket 11 to the notch 16.

In order to ensure the moving path of the slot member 20, a guide portion for guiding the movement of the slot member 20 may be provided on the base 14. Specifically, as shown in fig. 4, the guiding portion may be a sliding groove 141 on the base 14.

In this application, base 15 with can correspond to be provided with on the locking piece 40 and be used for only allowing under the unlocked state the locking piece is followed the unlocked state moves to the limit structure of locked state to prevent that locking piece 40 from rotating to opposite direction from the unlocked state, provide the feel of correct operation action for the operator simultaneously. Specifically, the middle portion of the rod 41 has a substantially elliptical cross-section for abutting against the socket 20, a boss 413 may be disposed at an end of the rod 41, and the base 15 may be provided with a limit protrusion 142 abutting against the boss 413 in an unlocked state. In the unlocked state, the boss 413 contacts the stopper projection 142, so that the lever body 41 can only rotate in a direction toward the locked state. If the operator rotates the lever 41 in the reverse direction, the operator will be blocked by the limiting protrusion 142 to get a tactile alert, and the operator can know the correct direction of the operation.

According to another aspect of the present application, a test assembly is provided, wherein the test assembly comprises a carrier 60 for receiving a test element and an electrical connector of the present application, the socket 11 being adapted to receive the carrier 60 such that the first contact 211 is in contact with a corresponding second contact 61 of the test element on the carrier 60.

The use of the test assembly of the preferred embodiment of the present application is described below in conjunction with the drawings. Wherein the lock member 40 includes a rod body 41 having a substantially elliptical cross section, and the outer periphery has a plane parallel to the axis as a lock portion 412 and an arc-shaped pressing portion 411, and the end of the rod body 41 has a grip 42 for operation. The base 10 comprises a base 14 and a top cover 15 which are clamped with each other. The top cover 15 is provided with two sockets 11, the middle part of the base 14 is provided with a fixed seat 13, and two sides of the fixed seat 13 are respectively provided with a shaft part 12 to wind two springs serving as the reset pieces 50, wherein the springs are in a free state of natural extension in an unlocking state. The base 14 and the top cover 15 together define a containing cavity of the locking member 40 and a limiting cavity of the spring, the two containing cavities are located at two side positions of the seat body 10, and the slot member 20 is located between the containing cavity and the fixed seat 13. As shown in fig. 7, a plurality of non-implanted ends are provided on the carrier 60. A plurality of first contacts 211 are provided in the socket 21 to contact the second contacts 61 of the respective non-implanted ends. When in use:

first, the electrical connector is put in the unlocked state, i.e. the slot 21 is aligned with the socket 11.

The carrier 60 is then placed into the slot 21 via the socket 11 such that the handle portion 63 of the carrier 60 corresponds to the location of the indentation 16. When the carrier 60 is placed in the socket 21, the first contact 211 is in contact with the second contact 61.

Subsequently, the corresponding lock member 40 is rotated, so that the pushing portion 411 pushes the slot member 20 to move toward the locked state until the lock member 40 rotates to be engaged with the concave portion 22 of the slot member 21 through the lock portion 412, and at this time, both sides of the slot member 20 abut against the lock member 40 and the spring respectively to be balanced, and the slot member is locked in the locked state. In the locked state, the test can be stably performed.

After the test is completed, the lock member 40 is rotated in the reverse direction, so that the lock portion 412 is disengaged from the recess 22, and the socket member 21 and the lock member 40 are returned to the unlocked state by the return force of the spring.

With the present application, locking and unlocking of the socket member 20, i.e., mounting and dismounting of the carrier 60, is accomplished by rotationally operating the locking member 40 without applying an additional force to the carrier 60, avoiding damage to the electrical components on the carrier 60 during mounting and dismounting.

The electrical connector and the test assembly are particularly suitable for the switching and testing of electrical elements which are small in size and easy to damage under repeated plugging and unplugging forces, such as non-implanted ends in the medical industry.

The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, many simple modifications can be made to the technical solution of the invention. The present application includes the combination of individual features in any suitable manner. The invention is not described in detail in order to avoid unnecessary repetition. Such simple modifications and combinations should be considered within the scope of the present disclosure as well.
