Background

In the prior art, an electrical connector is provided, which includes a male component and a female component each having an electrical terminal, wherein when the male component is connected to the female component, the electrical terminal in the male component is electrically connected to the electrical terminal in the female component.

Detailed Description

In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.

The following description of the embodiments of the connecting assembly disclosed in the present invention with reference to fig. 1 to 12 shows specific embodiments, and those skilled in the art can understand the advantages and effects of the present invention from the disclosure of the present specification. However, the following disclosure is not intended to limit the scope of the invention, and those skilled in the art can implement the invention in other different embodiments based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the drawings of the present invention are merely schematic illustrations and are not drawn to actual dimensions. Furthermore, although the terms first, second, third, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used primarily to distinguish between elements.

First embodiment

Referring to fig. 1 and 2, a connecting assembly according to a first embodiment of the present invention includes a first connector 1 shown in fig. 1 and a second connector 2 shown in fig. 2. The connecting component is applied to the electrical connection of an electronic equipment system, wherein a first connector 1 is arranged on first equipment in the system, and a second connector 2 is arranged on second equipment in the system. In detail, in the present embodiment, the connecting component is implemented as an electrical connector of the ultrasonic detector, wherein the first connector 1 is connected to the cable W of the ultrasonic probe, as shown in fig. 1; the second connector 2 is integrated with a monitor screen M (or, the first device is an ultrasonic probe, and the second device is a monitor screen or a host), as shown in fig. 2. However, the present invention is not limited thereto; in other embodiments, the connecting component can also be implemented as an electrical connector of other kinds of transmission equipment, wherein the first connector 1 and the second connector 2 are respectively integrated into one of a transmission plug and a transmission socket of the transmission equipment. In addition, in a variation, the first connector 1 can also be integrated into the monitor screen M, and the second connector 2 is connected to the cable W of the ultrasonic probe (or, the first device is the monitor screen or the host, and the second device is the ultrasonic probe).

Referring to fig. 1, the first connector 1 has a housing 13, and a first electrical terminal 11 and a first connector 12 disposed in the housing 13. The first connecting member 12 has a slot 120, and an end 1201 of the slot 120 forms an opening P at a side 121 of the first connecting member 12. In this embodiment, the number of the card slots 120 is two, however, the invention is not limited thereto, and the number of the card slots 120 may be any other number.

Referring to fig. 2, the second connector 2 has a second connector 22 and a second electrical terminal 21 corresponding to the first electrical terminal 11, wherein the second connector 22 has a number of protrusions 220 corresponding to the number and position of the slots 120. Preferably, for the convenience of assembly and connection, when the first connector 1 and the second connector 2 are connected and the relative position therebetween is as shown in fig. 3, the first electrical terminal located in the housing 13 is electrically connected to the second electrical terminal located in the screen M (for clarity, only the housing 13, the first connector 12, the screen M and the second connector 22 are shown in fig. 3, and other elements are omitted). Preferably, when the protrusion 220 of the second connector 22 is located at the opening P, the first electrical terminal 11 and the second electrical terminal 21 can contact each other to start electrical connection.

Further, the first connecting member 12 is movable between a starting position and a locking position, in fig. 3 and 4, the first connecting member 12 is in the starting position. Fig. 4 shows a schematic view of the first connector 12 and the second connector 22 in fig. 3. As shown in fig. 4, when the first connecting member 12 is located at the initial position, the protrusion 220 can enter one end 1201 of the slot 120 along the first direction D1 from the opening P of the first connecting member 12, so as to bring the first connector 1 and the second connector 2 into the relative positions shown in fig. 3.

Fig. 5 and 6 show the relative positions of the first connector 1 and the second connector 2 when the first connector 12 is located at the locked position, and fig. 6 is a schematic view of the first connector 12 and the second connector 22 in fig. 5. The protrusion 220 is movable in the card slot 120 along a second direction D2 after entering the end 1201 of the card slot 120 from the opening P in fig. 3, and the second direction D2 is not parallel to the first direction D1. In detail, in the embodiment, the protrusion 220 is substantially stationary, and when the first connector 12 moves from the initial position of fig. 3 to the locking position of fig. 5, the protrusion 220 moves from one end 1201 to the other end 1202 of the slot 120 relative to the first connector 12, as shown in fig. 6. In this embodiment, the second direction D2 is substantially parallel to the extending direction of the slot 120, and the extending direction of the slot 120 is substantially parallel to the side 121 of the first connecting element 12. Thus, when the protrusion 220 moves to the other end 1202 of the card slot 120, the first electrical terminal 11 of the first connector 1 can still be electrically connected to the second electrical terminal 21 of the second connector 2, and the first connector 1 can be locked to the second connector 2 by the mutual engagement between the protrusion 220 and the card slot 120, so that the connection between the first connector 1 and the second connector 2 is not easily loosened by an external force (for example, when the cable W is pulled), and the electrical connection between the first electrical terminal 11 and the second electrical terminal 21 is further strengthened.

Further, referring to fig. 6, in the present embodiment, a distance between one end 1201 of the card slot 120 close to the opening P and the other end 1202 far from the opening P and the side 121 is substantially the same. However, the present invention is not limited thereto. In other embodiments, the other end 1202 of the opening P may be designed to be farther away from the side 121 than the one end 1201 of the opening P, so that the protrusion 220 can enhance the contact force between the first connector 1 and the second connector 2 when moving along the slot 120 from the one end 1201 to the other end 1202.

Referring to fig. 6, in the present embodiment, the slot 120 is bent away from the side 121 to form a bent portion 1203. With the bent portion 1203, when the protrusion 220 of the second connecting member 22 moves to the other end 1202 of the slot 120, the protrusion is not easily moved back to the opening P along the slot 120 due to the blocking of the bent portion 1203, and is further locked to the other end 1202 of the slot 120. Therefore, the bent portion 1203 is disposed to further enhance the locking between the first connecting member 12 and the second connecting member 22. However, the invention is not limited to the above, and in other embodiments, the card slot 120 may not have the bent portion 1203, and the protrusion 220 is fastened to the other end 1202 of the card slot 120 by other structural methods.

Referring to fig. 7, a cross-sectional front view of the first joint 1 of fig. 3 along the cross-sectional line X is shown. In another variation of the present invention, the first connector 12 further includes a guiding slot 122 penetrating through the first connector 12, and the first connector 1 has a number of positioning protrusions 131 corresponding to the number of guiding slots 122. Preferably, the positioning salient point 131 may be arranged inside the housing 13 of the first connector 1, or may be arranged outside the housing 13 of the first connector 1; in another embodiment, the positioning bumps 131 can also be disposed adjacent to the first connector 1 in the device to which the first connector 1 is mounted. As shown in fig. 7, each positioning bump 131 is located in the guide slot 122, and the extending direction of the guide slot 122 is parallel to the second direction D2. The positioning protrusion 131 preferably has a size approximately equal to the width of the guiding slot 122, such that when the first connecting element 12 is displaced between the initial position and the locked position along the second direction D2 or opposite to the second direction D2 (fig. 7 illustrates the case where the first connecting element 12 is located at the initial position), the guiding slot 122 is guided by the positioning protrusion 123 to slide along the second direction D2 or opposite to the second direction D2, so as to assist the first connecting element 12 to be linearly displaced between the initial position and the locked position. This prevents the first connecting member 12 from shifting between the initial position and the locking position, and reduces the resistance of the protrusion 220 of the second connecting member 22 during displacement in the slot 120.

Referring to fig. 8, in an alternative embodiment, the first connector includes a button 14 connected to the first connecting member 12 (only the first connecting member 12, the second connecting member 22 and the button 14 are shown in fig. 8, and the rest of the components are omitted). In this variation, as shown in fig. 8, the first connecting member 12 further includes a button hole 123 for a portion of the button member 14 to be disposed therein, so that the button member 14 is locked with the first connecting member 12. However, the present invention is not limited thereto; in other embodiments, the button member 14 may be connected to the first connecting member 12 in other manners. In the present embodiment, by connecting the button member 14 to the first connecting member 12, the button member 14 drives the first connecting member 12 to actuate, so that the user can further control the displacement of the first connecting member 12 between the initial position and the locked position by controlling the button member 14 to move along the second direction D2 or opposite to the second direction D2 (fig. 8 is taken as an example when the first connecting member 12 is driven to the locked position by the button member 14). It should be emphasized that in other embodiments of the present invention, the first connecting member 12 can be moved between the initial position and the locking position by other mechanisms, and is not limited to the button member 14 of this variation.

Fig. 9A is a schematic cross-sectional view of the first connector 1 when the first connecting element 12 is located at the initial position. Specifically, in the present variation, the button 14 has at least one hook structure 141, and the first connector 1 includes a tenon 151 disposed at an end of a moving path of the button, so that when the button 14 drives the first connecting element 12 to move to the locking position (as shown in fig. 9B), the hook structure 141 can be engaged with the tenon 151. In this embodiment, the protrusion 220 of the second connector 22 moves to the other end 1202 of the slot 120 when the first connector 12 moves to the locking position, and is fixed to the end 1202 by the arrangement of the hook structure 141 and the tenon 151, so that this variation can further strengthen the protrusion 220 fixed to the other end 1202 of the slot 120, and prevent the protrusion 220 from moving back to the end 1201 of the slot 120 close to the opening P in the direction opposite to the second direction D2 when the first electrical terminal 11 is electrically connected to the second electrical terminal 21, or even sliding out of the slot 120 from the opening P, thereby causing the interruption of the electrical connection.

Referring to fig. 9A and 9B, in addition, in the present embodiment, the button 14 further includes a second hook structure 142, and the first connector 1 has a second tenon 152 correspondingly. By the arrangement of the second hook structure 142 and the second tenon 152, when the first connecting member 12 is located at the initial position, the second hook structure 142 and the second tenon 152 can be engaged with each other, as shown in fig. 9A. Thus, the first connecting element 12 can be fixed relative to the housing 13 by the locking mechanism of the hook structure (141, 142) and the locking tenon element (151, 152) in both the initial position and the locking position. Thus, the first connecting member 12 can be switched between three states of "being locked at the initial position", "being locked at the locked position", and "moving between the initial position and the locked position", so as to reduce the requirement of the user to adjust the position of the button member 14, and further facilitate the operation of the user on the first connector 1.

In summary, in the embodiment, by the arrangement of the slot 120 of the first connecting element 12 and the protrusion 220 of the second connecting element 22, the first connector 1 and the second connector 2 can be aligned by the protrusion 220 and the slot 120 when connected, so as to reduce the probability of misalignment during connection, and on the other hand, by the engagement between the protrusion 220 and the slot 120, the electrical connection between the first electrical terminal 11 of the first connector 1 and the second electrical terminal 21 of the second connector 2 is enhanced, and the influence of external force factors such as impact and pulling on the connection assembly on the electrical connection between the first electrical terminal 11 and the second electrical terminal 21 is avoided.

In addition, by the bent portion 1203 of the card slot 120, the present embodiment can enhance the engagement between the protruding portion 220 and the card slot 120, and further enhance the electrical connection between the first electrical terminal and the second electrical terminal 21. Preferably, the present embodiment further includes a button 14, wherein a user can control the first connecting element 12 to move between the initial position and the locking position by operating the button 14, and the hook 141 of the button and the tenon 151 of the first connector 1 can make the first connecting element 12 engage with the housing 13 when moving to the initial position and the locking position, respectively. In this way, on the one hand, the electrical connection between the first electrical terminal 11 and the second electrical terminal 21 can be further strengthened, and on the other hand, the operation of the button 14 by the user is also facilitated.

Second embodiment

Please refer to fig. 10 to 12, which illustrate schematic views of a connecting assembly according to a second embodiment of the present invention in different operating states. The main difference between the present embodiment and the previous embodiment is that in the previous embodiment, the first connecting member 12 can be moved between the initial position and the locking position by being driven by the button member 14; in this embodiment, the first connecting element 12 is actuated between the initial position (shown in fig. 11) and the locking position (shown in fig. 12) by an elastic element 16 disposed in the housing 13, and the engaging groove 120 has a structure corresponding to such an actuation manner (described below). For clarity, fig. 10 to 12 only show the first connecting member 12, the second connecting member 22 and the elastic member 16, and the rest elements are omitted. In addition, the same elements in the second embodiment as those in the first embodiment are denoted by the same element numbers, and the structure and function thereof are substantially the same as those in the previous embodiment, and are not repeated in this embodiment.

Referring to fig. 10, the relative position of the first connector 12 and the second connector 22 is shown before alignment, wherein the protrusion 220 of the second connector 22 is aligned with the opening P of the slot 120 of the first connector 12. In fig. 10, the first end 161 of the elastic member 16 is configured to be connected to the inside of the housing 13 of the first connector 1, the second end 162 is configured to be connected to the first connecting member 12, and the elastic member 16 is in a compressed or natural extension state. Specifically, the "compression" is relative to the balance point of the system of resilient members 16 and first connecting member 12. For example, in the present embodiment, the balance point refers to a position where the elastic member 16 is stretched by the gravity of the first connecting member 12 and then is stationary.

As shown in fig. 10, in the present embodiment, the card slot 120 has a turning portion 1204, wherein the opening P to the turning portion 1204 defines a first direction D1, the turning portion to the other end 1202 of the card slot 120 defines a second direction D2, and the first direction D1 is not parallel to the second direction D2. Referring to fig. 11, more specifically, the first direction D1 has a component opposite to the second direction D2, and the extending direction of the elastic element 16 is substantially parallel to the second direction D2, such that when the protrusion 220 enters the slot 120 along the first direction D1 and is located at the turning portion 1204, the elastic element 16 is further compressed to generate a restoring force along the third direction D3, wherein the third direction D3 is opposite to the second direction D2. In other words, the length L1 of the elastic member 16 in FIG. 10 is greater than the length L2 of the elastic member 16 in FIG. 11.

Referring to fig. 12, according to the above-mentioned technical solution, when the protrusion 220 enters the slot 120 and moves to the turning portion 1204, the first connecting element 12 can be driven by the elastic element 16 to move along the third direction D3, and meanwhile, since the second connector 2 is in a stationary state relative to the first connector 1, the protrusion 220 on the second connecting element 22 will move from one end 1201 of the slot 120 close to the opening P to the other end 1202 of the slot 120 along the second direction D2 relative to the first connecting element 12. In the embodiment, when the protrusion 220 is located at the turning portion 1204, the first electrical terminal 11 of the first connector 1 is electrically connected to the second electrical terminal 21 of the second connector 2, and when the protrusion 220 moves to the other end 1202 of the card slot 120 and is clamped to the end 1202 of the card slot 120, the electrical connection between the first electrical terminal 11 and the second electrical terminal 21 can be further prevented from being broken due to the influence of external force.

In addition, the elastic member 16 in fig. 12 is preferably in a natural stretched or slightly compressed state. Therefore, when the elastic element 16 is in a natural extension state in fig. 12, that is, the elastic element 16 is extended to a balance point only by the gravity of the first connecting element 12, and at this time, because the elastic element 16 is in a static balance state, the interaction force between the protruding portion 220 and the slot 120 is extremely small, so that the protruding portion 220 can be prevented from leaving the other end 1202 of the slot 120 due to the force; when the elastic member 16 is in the micro-compressed state in fig. 12, the elastic member 16 has a restoring force along the third direction D3, so that an interaction force between the protrusion 220 and the other end 1202 of the slot 120 along the second direction D2 (protrusion 220 to slot 120) and the third direction D3 (slot 120 to protrusion 220) is provided between the protrusion 220 and the other end 1202 of the slot 120, and the engaging force of the protrusion 220 in the slot 120 is increased.

It should be noted that fig. 10 to 12 are only one embodiment of the present invention, and the present invention is not limited thereto. For example, in fig. 10 to 12, the elastic member 16 is disposed above the first connecting member 12, and in another variation, the elastic member 16 may be disposed below the first connecting member 12, for example. In this variation, when the protrusion 220 of the second connector 22 does not enter the slot 120, the elastic member 16 is in a natural compression state; then, by moving the first connecting member 12, the elastic member 16 is stretched until the protrusion 220 is at the same height as the opening P of the side 121 and can enter the slot 120; when the protrusion 220 moves from the opening P to the turning portion 1204 relative to the first connecting element 12, the elastic element 16 further extends and has a restoring force along the third direction D3, so that the elastic element 16 drives the first connecting element 12 to move along the third direction D3, the protrusion 220 moves from the end 1201 of the card slot 120 close to the opening P to the other end of the card slot 120 along the second direction D2.

In this embodiment, by the arrangement of the elastic element 16 and the bent portion 1204 of the card slot 120, after the protruding portion 220 enters the bent portion 1204 of the card slot 120, the protruding portion can move to the other end 1202 of the card slot 120 relative to the first connecting element 12 by the restoring force of the elastic element 16, so as to enhance the electrical connection between the first electrical terminal 11 and the second electrical terminal 21, and simplify the fastening mechanism between the protruding portion 220 and the card slot 120. In addition, the invention does not limit the releasing manner of the clamping mechanism between the first connecting piece 12 and the second connecting piece 22. For example, in one embodiment, the protrusion 220 can be moved away from the engagement position by providing a button on the first connector 12 to move the first connector 12, or in another embodiment, the housing 13 can be pulled by hand to compress the resilient member 16 to move the first connector 12 away from the second connector 22.

In summary, by the technical solution of the embodiment of the present invention, in the connecting assembly of the present invention, through the technical solutions that "the opening P is formed at the side 121 of the first connector 12 by the one end 1201 of the slot 120" and "when the first connector 12 is at the initial position, the protrusion 220 of the second connector 22 can enter the slot 120 from the opening P along the first direction D1", so that when the first connector 12 moves from the initial position to the locking position, the protrusion 220 moves in the slot 120 along the second direction D2, and the first electrical terminal can always maintain the electrical connection with the second electrical terminal during the movement of the first connector 12 relative to the second connector 13. Due to the mutual matching of the first connecting piece and the second connecting piece, even if the ultrasonic probe/machine table moves and pulls the cable in the detection execution process, the first connecting piece and the second connecting piece in the connecting assembly can still keep stable electric connection of the first electric terminal and the second electric terminal within a certain relative displacement range.
