Description

Technical Field

[0001] The utility model relates to a connector component, and more specifically, to a connector component with an anti-electric shock function. Background Art

[0002] The connector assembly forms an electrical connection for current flow by assembling two connectors together. However, in the prior art, especially when the two connectors have not yet been assembled together, the live parts inside the connector assembly are not completely isolated from the outside, causing potential safety hazards such as electric shock to personnel.

[0003] Therefore, it is desirable to provide a connector assembly that can reduce or even eliminate the above-mentioned potential safety hazards. Utility Model Content

[0004] According to one aspect of the utility model, a connector assembly is proposed, comprising a first connector and a second connector, the first connector and the second connector being detachably assembled together, each of the first connector and the second connector comprising: a shell having: a bottom surface extending along an insertion direction; a first step portion extending along the insertion direction, opposite to the bottom surface; a second step portion extending along the insertion direction at a front side of the first step portion, opposite to the bottom surface, and closer to the bottom surface than the first step portion; a front opening arranged at the front side of the shell; a rear opening arranged at the rear side of the shell; a step opening arranged on the second step portion; a cavity formed by being partially surrounded by the shell; a pin in the cavity; a wire, one end of which is electrically connected to the pin and the other end of which is opened from the rear side extrude; wherein each of the first connector and the second connector further comprises: a slide plate capable of sliding on the second step portion between a first position that closes the step opening and a second position that does not close the step opening; a baffle plate fixed on the second step portion and on the front side of the slide plate, and when the connector assembly is assembled, the baffle plate of one of the first connector and the second connector drives the slide plate of the other of the first connector and the second connector to move from the first position to the second position; an elastic component, wherein the pin abuts against the elastic component, so that the pin of the first connector and the pin of the second connector are biased toward their respective step openings under the action of their respective elastic components, so that when the step opening is not closed, the pin of the first connector and the pin of the second connector can contact each other.

[0005] According to this solution, when the two connectors are not yet assembled together, the slide plate can close the opening on the second step portion of the connector housing, and when the two connectors are assembled, the slide plate of one connector is pushed open by the baffle plate of the other connector to expose the opening on the second step portion, providing space for the electrical contact of the pins of the two connectors. This avoids the exposure of the openings for pin contact on the respective connectors to the external environment when the two connectors are not yet assembled together, reducing or even eliminating the risk of accidental electric shock from the opening.

[0006] In some aspects, a baffle may close the front opening.

[0007] According to this solution, the front opening of the connector is prevented from being exposed to the external environment when the two connectors have not yet been assembled together, thereby reducing the risk of accidental electric shock from the front opening of the connector and further improving the safety of the connector.

[0008] In some aspects, each of the first connector and the second connector may further include a rear cover, which is arranged at the rear opening of the housing to partially close the rear opening, wherein the rear cover is provided with a through hole, and the wire extends through the through hole.

[0009] According to this solution, the rear opening of the connector is prevented from being exposed to the external environment, reducing the risk of accidental electric shock from the rear opening of the connector, thereby further improving the safety of the connector.

[0010] In some embodiments, the baffle may have a baffle protrusion protruding in a direction away from the bottom surface, and the skateboard may have a skateboard protrusion protruding in a direction away from the bottom surface. When the connector assembly is assembled, the baffle protrusion of one of the first connector and the second connector contacts the skateboard protrusion of the other of the first connector and the second connector to drive the skateboard protrusion of the other of the first connector and the second connector to move.

[0011] In some embodiments, the slide plate protrusion may have a first protrusion and a second protrusion extending along the insertion direction and spaced apart from each other, the first protrusion and the second protrusion include an entrance section located on the front side and approaching each other and a channel section with a constant width on the rear side of the entrance section, the entrance section is made of an elastic material, the size of the baffle protrusion is larger than the size of the entrance section, and the size of the baffle protrusion is smaller than the size of the channel section.

[0012] According to this solution, the baffle protrusion can make the entrance section elastically deform and enter the entrance section of the skateboard protrusion, and then move in the channel section of the skateboard protrusion, so that even if the skateboard is blocked and cannot move, the baffle can still drive the pin to move along the shell, reducing the demand for the moving stroke of the skateboard, which is conducive to the miniaturization of the entire component.

[0013] In some embodiments, a blocking surface can be formed at the boundary between the second step portion and the first step portion. When the slide moves to the blocking surface and is blocked by the blocking surface, the baffle of one of the first connector and the second connector passes through the entrance section of the other of the first connector and the second connector into the corresponding channel section and continues to move in the corresponding channel section.

[0014] In some embodiments, the skateboard may have a skateboard retaining portion, and the baffle may have a baffle retaining portion. When the first connector is not assembled with the second connector, the skateboard retaining portion of the first connector is retained in a first position by the baffle retaining portion of the first connector, and the skateboard retaining portion of the second connector is retained in the first position by the baffle retaining portion of the second connector.

[0015] According to this solution, when the connector assembly has not yet been assembled, the slide plate is maintained in a position that closes the step opening by the cooperation between the slide plate retaining portion and the baffle retaining portion, so that the slide plate will not accidentally leave the position of the closed step opening due to other disturbances to cause potential risk of electric shock, thereby further enhancing the safety of the connector assembly.

[0016] In some embodiments, the elastic component may be provided with a connection hole, and the pin may be provided with a pin protrusion, and the pin protrusion is inserted into the connection hole.

[0017] In some solutions, the elastic component may be a spring sheet having a curved surface and a flat portion, the connecting hole is provided on the curved surface, and the flat portion is provided with a fixing hole for fixing the spring sheet to the housing.

[0018] In some embodiments, both ends of the curved surface may contact the bottom surface of the housing, with one end being fixed and the other end being able to move along the bottom surface of the housing.

[0019] In some embodiments, the shell may also include a locking portion and a mating locking portion. When the first connector and the second connector are assembled in place, the locking portion of the first connector cooperates with the mating locking portion of the second connector, and the locking portion of the second connector cooperates with the mating locking portion of the first connector to lock the first connector and the second connector together.

[0020] In some solutions, the first connector and the second connector may be completely identical, and when the first connector and the second connector are assembled in place, the second step portion of the first connector faces the second step portion of the second connector.

DETAILED DESCRIPTION

[0037] In order to make the purpose, scheme and advantages of the technical solution of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described in conjunction with the drawings of the specific embodiments of the utility model. Unless otherwise specified, the terms used in this article have the usual meanings in the art. The same reference numerals in the drawings represent the same components.

[0038] For a clearer description, unless otherwise expressly stated, the meanings of the directional terms appearing in this article are as follows: insertion direction refers to the respective moving directions of the connectors when the two connectors are assembled together, the front side refers to the side close to the other connector when the two connectors are assembled together, and the rear side refers to the side away from the other connector when the two connectors are assembled together.

[0039] Figure 1 A schematic diagram of a connector assembly 10 according to an embodiment of the present utility model is shown, and the connector assembly 10 is formed by assembling a first connector 100 and a second connector 200 together along an insertion direction. Because the first connector 100 is very similar to or even completely identical to the second connector 200, for the sake of brevity, the first connector 100 will be described in detail below, and unnecessary repetitive descriptions of the second connector 200 will be omitted. It should be understood that, in the following, the technical features described for the first connector 100 are basically also applicable to the second connector 200.

[0040] Figure 2 The schematic diagram of the first connector 100 according to the embodiment of the utility model is shown. The first connector 100 mainly includes a housing 110, a cavity 120 partially surrounded by the housing 110, a pin 130 and a wire 140 in the cavity 120, one end of the wire 140 is electrically connected to the pin 130, and the other end extends from the rear of the housing 110 to be electrically connected to an external device. Figure 3 and Figure 4As shown, the housing 110 includes a bottom surface 111 extending in the insertion direction, a first step portion 112 and a second step portion 113, and a front opening 114 and a rear opening 115 respectively arranged at the front and rear sides of the housing 110. The housing 110 has a step opening 116 for the pins 130 of the first connector 100 to contact the pins 230 of the second connector 200, and the step opening 116 is arranged on the second step portion 113. When the first connector 100 and the second connector 200 are assembled together, the second step portion 113 of the first connector 100 faces the second step portion of the second connector 200, and the current can be conducted in the connector assembly 10 via the wire 140 of the first connector 100, the pin 130 of the first connector 100, the pin 230 of the second connector 200, and the wire 240 of the second connector 200 in sequence (such as Fig. 6A and Figure 6B shown).

[0041] The openings (front opening 114, rear opening 115, and step opening 116) of the housing 110 facilitate wiring, but because the openings are exposed to the external environment, they also create potential safety hazards (for example, a person accidentally contacts a live component (for example, pin 130) inside the housing 110 through the opening, thereby causing an electric shock accident). In particular, for the step opening 116, because the live pin 130 protrudes from the step opening 116 to electrically contact with the pin of another connector, an electric shock accident is more likely to occur.

[0042] In order to reduce the above-mentioned safety hazards, the first connector 100 further includes a slide plate 150 for closing the step opening 116, a baffle plate 160 for driving the slide plate 150 to move, and an elastic component 170 for biasing the pin 130. Specifically, the slide plate 150 can move from a first position to a second position on the second step portion 113. In the first position, the slide plate 150 closes the step opening 116 (corresponding to the unassembled state of the connector assembly 10), and in the second position, the slide plate 150 does not close the step opening 116 (corresponding to the assembled state of the connector assembly 10). The baffle plate 160 is fixed to the second step portion 113 and is at the front side of the slide plate 150. When the connector assembly 10 is assembled, the baffle plate 160 of the first connector 100 drives the slide plate of the second connector 200 to move from the first position to the second position. The pin 130 abuts against the elastic component 170, so that the pin 130 of the first connector 100 and the pin 230 of the second connector 200 are biased toward their respective step openings 116 under the action of their respective elastic components 170. According to the connector assembly 10 as described above, when the connector assembly 10 is in an unassembled state, the slide plate 150 closes the step opening 116 to ensure that no electric shock accident (such as Figure 5A and Figure 5BWhen the connector assembly 10 is assembled, the baffle 160 moves the slide plate 150 to expose the step opening 116, and then the pins 130 contact each other through the step opening 116 under the action of the elastic member 170, thereby achieving electrical connection between the first connector 100 and the second connector 200.

[0043] Preferably, the baffle 160 of the first connector 100 can close the front opening 114 of the housing 110 of the first connector 100. In this way, when the connector assembly 10 is not assembled, the front opening 114 of the first connector 100 is prevented from being exposed to the external environment, thereby reducing the risk of accidental electric shock from the front opening 114 of the first connector 100, and further improving the safety of the connector assembly 10.

[0044] Preferably, if Fig.13 As shown, the first connector 100 may further include a rear cover 180, which is arranged at the rear opening 115 of the housing 110 to partially close the rear opening 115, wherein the rear cover 180 is provided with a through hole 182 (such as Fig.12 As shown in FIG. 1 , the wire 140 extends out through the through hole 182 to be electrically connected to an external device. In this way, the rear opening 115 of the first connector 100 is prevented from being exposed to the external environment, reducing the risk of accidental electric shock from the rear opening 115 of the first connector 100, thereby further improving the safety of the connector assembly 10.

[0045] Optionally, the baffle 160 may have a baffle protrusion 162 protruding in a direction away from the bottom surface 111 of the shell 110, and the slide plate 150 may have slide plate protrusions 152, 154 protruding in a direction away from the bottom surface 111 of the shell 110. When the connector assembly 10 is assembled, the baffle protrusion 162 of the first connector 100 contacts the slide plate protrusions 152, 154 of the second connector 200 to drive the slide plate protrusions 152, 154 of the second connector 200 to move from the first position to the second position to expose the step opening 116, thereby providing space for the pins 130 of the first connector 100 and the pins 230 of the second connector 200 to contact each other.

[0046] Preferably, if Figure 7As shown, the slide plate protrusion may include a first protrusion 152 and a second protrusion 154 extending in the insertion direction and spaced apart from each other, the first protrusion 152 and the second protrusion 154 including an entrance section 156 located at the front side and approaching each other and a channel section 158 having a constant width at the rear side of the entrance section 156, at least the entrance section 156 in the slide plate 150 is made of an elastic material, and the size of the baffle protrusion 162 is larger than the size of the entrance section 156 and smaller than the size of the channel section 158. In this way, the baffle protrusion 162 can make the entrance section 158 elastically deform (for example, open outward) and enter the entrance section 156 of the slide plate protrusion, and then move in the channel section 158 of the slide plate protrusion, so that even if the slide plate 150 is blocked and cannot move, the baffle 160 can still move on the slide plate of the other connector until the baffle 160 also moves to the blocking surface 118 and is blocked by the blocking surface 118, and the assembly between the first connector 100 and the second connector 200 is completely completed. The above arrangement reduces the requirement for the movement of the slide plate 150, which is conducive to the miniaturization of the entire assembly. At the same time, the entrance section 156 made of elastic material can provide tactile feedback to the user during the assembly of the connector assembly 10, so that the user can feel the progress of the assembly.

[0047] Preferably, a blocking surface 118 may be formed at the boundary between the second step portion 113 and the first step portion 112. When the slide plate 150 of the first connector 100 moves to the blocking surface 118 and is blocked by the blocking surface 118, although the step opening 116 of the first connector is no longer closed by the slide plate 150 of the first connector 100 (at the same time, the step opening of the second connector 200 is no longer closed by the slide plate of the second connector 200), at this time, the step opening 116 of the first connector is closed by the baffle of the second connector 200 (such as Figure 5A and Figure 5B Next, the baffle of the second connector 100 passes through the inlet section 156 of the slide plate 150 of the first connector 100 and enters the corresponding channel section 158 and continues to move in the corresponding channel section 158 until the baffle of the second connector 200 no longer closes the step opening 116, so as to provide space for the contact between the pin 130 of the first connector 100 and the pin 230 of the second connector 200 (as shown in FIG. Fig. 6A and Figure 6B shown).

[0048] Preferably, the slide plate 150 may have a slide plate holding portion 159, and the baffle plate 160 may have a baffle plate holding portion 164 (eg, Figure 8 When the first connector 100 is not assembled with the second connector 200, the slide plate holding portion 159 of the first connector 100 is held in the first position (as shown in FIG. Fig. 9As described above). In this way, when the connector assembly 10 has not been assembled, the slide plate 150 is maintained at a position that closes the step opening 116 by the cooperation between the slide plate retaining portion 159 and the baffle retaining portion 164, so that the slide plate 150 will not accidentally leave the position of closing the step opening 116 due to other disturbances to cause a potential risk of electric shock through the step opening 116, further enhancing the safety of the connector assembly 10. When the connector assembly 10 is assembled, the thrust of the baffle of the second connector 200 pushing the slide plate 150 of the first connector 100 is greater than the holding force of the baffle retaining portion 164 of the first connector 100 on the slide plate retaining portion 159 of the first connector 100, so that the slide plate 150 of the first connector 100 overcomes the holding force of the baffle retaining portion 164 on the slide plate retaining portion 159 and moves.

[0049] Preferably, the elastic component 170 may be provided with a connection hole 176, and the pin 130 may be provided with a pin protrusion 132 (such as Fig.10 As shown), the pin protrusion 132 is inserted into the connection hole 176. In addition, as shown Fig.11 As shown, the elastic member 170 may be a spring sheet having a curved surface 172 and a flat portion 174, a connecting hole 176 being provided on the curved surface 172, and a fixing hole 178 for fixing the spring sheet 170 to the housing 110 being provided on the flat portion 174. More preferably, both ends of the curved surface 172 may contact the bottom surface 111 of the housing 110, and one end ( Figure 5A and Figure 5B The right end of the Figure 5A and Figure 5B The left end of the housing 100 can slide along the bottom surface 111 of the housing 100. It should be understood that the left and right directions in the figure are only examples.

[0050] In addition, the housing 110 may further include a locking portion 190 and a mating locking portion 192. When the first connector 100 and the second connector 200 are assembled in place, the locking portion 190 of the first connector 100 cooperates with the mating locking portion of the second connector 200 to lock the first connector 100 and the second connector 200 together. When it is necessary to disassemble the connector assembly 10, press (for example, Fig. 6A and Figure 6B The pressing portion 194 is pressed downward in the middle of the connector 190 to rotate the locking portion 190 in a direction away from the housing 110, thereby unlocking the locking portion 190 and the mating locking portion 192, and then a pulling force is applied in a direction opposite to the insertion direction to disassemble the first connector 100 from the second connector 200. In this way, the self-locking structure makes it difficult for the connector assembly 10 to be disassembled by unexpected external disturbances when the connector assembly 10 is in an assembled state, thereby enhancing the stability of the connector assembly 10.

[0051] This document describes in detail several exemplary embodiments of the present invention with reference to preferred embodiments. However, it will be understood by those skilled in the art that, without departing from the concept of the present invention, various modifications and variations may be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present invention may be combined without exceeding the protection scope of the present invention, which is determined by the appended claims.
