Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an electrical connector. Background Art

[0002] Electrical connectors are also often referred to as circuit connectors or electronic connectors, which can be used to bridge two electrical components on a circuit, enabling current or signals to flow from one electrical component to another. Since electrical connectors are easy to be made into standardized components and have high electrical connection reliability, they are particularly suitable for modular components.

[0003] In the related art, an electrical connector generally includes a wire end component (connector male head) and a board end component (connector female socket). The wire end component is used to be inserted into the board end component to achieve electrical connection. Among them, raised board end terminals are usually arranged in the board end component, and the board end terminals are docked with the interfaces in the wire end component. During use, the wire end component is likely to tilt during the process of being inserted into the board end component, making the contact position between the wire end component and the board end terminals inaccurate. In this case, if the wire end terminals continue to be inserted into the board end terminals, it will cause problems such as the board end terminals being squeezed and deformed or even damaged. Summary of the Utility Model

[0005] An electrical connector includes a wire end component including an extending end, and a wire end terminal is arranged in the extending end; a board end component provided with a slot, and a board end terminal protrudes from the bottom wall of the slot; the slot is used to insert the extending end so that the board end terminal is cooperatively connected with the wire end terminal; a first anti-misinsertion structure arranged on the outer side wall of the extending end; a second anti-misinsertion structure arranged on the inner side wall of the slot; when the extending end is skewed during the process of moving into the slot, as the skewing amount increases, the first anti-misinsertion structure and the second anti-misinsertion structure are gradually clamped tightly to limit the skewing amount; a plurality of terminal locking members respectively fix the wire end terminals on the opposite side surfaces of the extending end to determine the relative positions of the wire end terminals and the board end terminals.

[0006] In one of the embodiments, the plurality of terminal locking members include: a first locking member fixedly corresponding to the wire end terminal on the upper wall of the extending end; and a plurality of second locking members sequentially and spacedly distributed corresponding to the first locking member on the lower wall of the extending end.

[0007] In one of the embodiments, the distance between the end of the board end terminal and the notch of the slot is greater than the depth of the extending end inserted into the slot when the first anti-misinsertion structure and the second anti-misinsertion structure are stuck to each other.

[0008] In one embodiment, when the first anti-misinsertion structure and the second anti-misinsertion structure are stuck to each other, the distance between the end of the protruding end and the board-end terminal is greater than 5 mm.

[0009] In one embodiment, the first anti-misinsertion structure includes a plurality of chutes extending along the direction in which the protruding end is inserted into the slot and the outer side wall of the end of the protruding end; the second anti-misinsertion structure includes a plurality of strip-shaped protrusions and the inner side wall of the slot opening. The strip-shaped protrusions correspond to the chutes one by one; there is a first clearance fit between the strip-shaped protrusions and the two side walls of the chutes and between the outer wall of the protruding end and the inner wall of the slot in the width direction of the electrical connector; there is a second clearance fit between the outer side wall of the end of the protruding end and the inner side wall of the slot opening in the height direction of the electrical connector; during the process of inserting the protruding end into the slot, when the inclination angle of the protruding end in the width direction of the electrical connector is greater than a first angle, the strip-shaped protrusion abuts against and is stuck to the two side walls of the corresponding chute; when the inclination angle of the protruding end in the height direction of the electrical connector is greater than a second angle, the outer side wall of the protruding end abuts against and is stuck to the inner side wall of the slot opening.

[0010] In one embodiment, the first clearance is equal to the second clearance, and the first angle is equal to the second angle, and both are 5° to 16°.

[0011] In one embodiment, the outer end of the chute is flush with the end of the protruding end; one end of the strip-shaped protrusion corresponding to the chute is flush with the port of the slot, or one end of the strip-shaped protrusion corresponding to the chute protrudes outside the port of the slot. In one embodiment, the protruding end includes a plurality of jacks, and the plurality of jacks extend from the end face of the protruding end to the inside of the protruding end corresponding to the board-end terminal; wire-end terminals are provided in the jacks; the mating length between the board-end terminal and the wire-end terminal is greater than 1 mm.

[0012] In one embodiment, the number of the chutes is multiple, and a plurality of the chutes are symmetrically arranged on the outer side walls on both sides of the protruding end along the height direction of the protruding end; along the width direction of the protruding end, a plurality of the chutes are spaced apart and distributed on the outer wall of the protruding end.

[0013] In one embodiment, along the width direction of the protruding end, a plurality of the chutes are symmetrically distributed with respect to the midline in the width direction of the protruding end.

[0014] In one embodiment, an anti-wear pad is provided on the inner wall of the slot corresponding to the end of the protruding end; the materials of the first anti-misinsertion structure, the second anti-misinsertion structure and the anti-wear pad are all plastic materials.

[0015] The above electrical connector has at least the following beneficial effects:

[0016] Since the electrical connector includes a wire-end component and a board-end component, the wire-end component, as the male connector of the connector, includes a protruding end, and the board-end component, as the female connector of the connector, is provided with a slot. When the wire-end component is inserted and connected to the board-end component, the protruding end is inserted into the slot. A board-end terminal protrudes from the bottom of the slot, and a jack is provided at one end of the protruding end extending into the slot. The board-end terminal is inserted into the jack to contact and connect with the wire-end terminal (PIN needle) in the jack, realizing the electrical connection between the wire segment connector and the board-end component. A first anti-misinsertion structure is provided on the side wall of the end of the protruding end, and a second anti-misinsertion structure is provided on the inner wall of the slot. When the protruding end is vertically inserted into the slot, the board-end terminal can accurately be inserted into the jack to be butt-connected with the protruding end. When the protruding end is inserted into the slot in a skewed state, the interfaces of the board-end terminal and the protruding end cannot accurately correspond. Before the protruding end touches the board-end terminal, the first anti-misinsertion structure and the second anti-misinsertion structure are mutually abutted and jammed to limit the protruding end from continuing to move into the slot, so that the protruding end will not touch the board-end terminal, avoiding the board-end terminal from being squeezed and deformed and damaged. Only when the insertion angle of the protruding end is adjusted so that it is no longer skewed or the skewed angle is within the specified range, the first anti-misinsertion structure and the second anti-misinsertion structure are released from the jammed state, enabling the protruding end to continue to move into the slot. In this case, the board-end terminal and the wire-end terminal can accurately correspond, enabling the board-end terminal to be smoothly inserted into the wire-end interface to realize the electrical connection between the wire-end component and the board-end component, reducing misinsertion and improving the service life and connection safety of the connector.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] Referring to Figures 1 to 11 as shown, this utility model discloses an electrical connector 10, which includes a wire-end assembly 11, a board-end assembly 12, a first anti-misinsertion structure 113, a second anti-misinsertion structure 123 and a plurality of terminal locking members 16. The wire-end assembly 11 is pluggably connected to the board-end assembly 12 and is plugged and unplugged in accordance with the Figure 2 and Figure 6 plugging direction therein to achieve electrical connection. The wire-end assembly 11 and the board-end assembly 12 can be respectively connected to two electrical components, and the two electrical components are electrically connected by plugging and connecting the wire-end assembly 11 and the board-end assembly 12 to perform power transmission or data transmission. In some embodiments, the wire-end assembly 11 can be used to connect an electronic control module of an electrical device (such as a medical device, a household appliance, etc.), and the board-end assembly 12 can be used to connect another electronic control module of the same electrical device. By plugging and connecting the wire-end assembly 11 and the board-end assembly 12, the electrical connection between the two electronic control modules is achieved, and then the current and data transmission between the two electronic control modules is realized. Exemplarily, the wire-end assembly 11 is connected to the display of a medical device, and the board-end assembly 12 is connected to the controller of the medical device. After the wire-end assembly 11 and the board-end assembly 12 are connected, the current and data transmission between the controller and the display can be realized.

[0037] Referring to Figure 1 , Figure 12 , Figure 13 and Figure 14As shown, both the wire-end component 11 and the board-end component 12 are rectangular blocks. The wire-end component 11 includes a protruding end 111, which is also in the shape of a rectangular block. The board-end component 12 includes a slot 121, and the shape of the slot 121 matches the shape of the protruding end 111. A wire-end interface 112 is provided on the protruding end 111. A board-end terminal 122 adapted to the wire-end interface 112 protrudes from the bottom wall of the slot 121. The board-end terminals 122 correspond to the wire-end interfaces 112 one by one. The slot 121 is used to insert the protruding end 111 so that the board-end terminals 122 are embedded in the wire-end interfaces 112 to realize the electrical connection between the wire-end component 11 and the board-end component 12. During the process of continuously inserting the protruding end 111 into the slot 121, the wire-end interface 112 faces and gets closer to the bottom of the slot 121 until the board-end terminal 122 is inserted into the corresponding wire-end interface 112 and makes contact connection with the wire-end terminal 1122 inside the wire-end interface 112, thus realizing the electrical connection between the wire-end component 11 and the board-end component 12. A first anti-misinsertion structure 113 is provided on the side wall of the end of the protruding end 111; a second anti-misinsertion structure 123 corresponds to the first anti-misinsertion structure 113 and is provided on the inner side wall of the slot 121; the protruding end 111 and the slot 121 are rectangular blocks that cooperate with each other. For the convenience of installation, the outer dimension of the protruding end 111 is smaller than the inner dimension of the slot 121. During the process of the protruding end 111 being inserted obliquely into the slot 121, one end of the outer wall of the end of the protruding end 111 first inserts into the slot 121. At this time, without restriction, if one end of the protruding end 111 inserts too much into the slot 121, it will contact the top of the board-end terminal 122 in the slot 121, causing extrusion, resulting in deformation of the board-end terminal 122, and causing misalignment between the board-end terminal 122 and the wire-end interface 112, making it impossible to install. The first anti-misinsertion structure 113 and the second anti-misinsertion structure 123 are set to cooperate. During the process of the protruding end 111 of the wire-end component 11 being inserted obliquely into the slot 121, the first anti-misinsertion structure 113 and the second anti-misinsertion structure 123 are clamped with each other due to the angle inclination to limit the movement of the protruding end 111 into the slot 121. As the deflection angle of the protruding end 111 increases, the first anti-misinsertion structure 113 and the second anti-misinsertion structure 123 are gradually clamped. When the deflection angle of the protruding end 111 is greater than the critical angle, that is, along the width direction of the electrical connector 10, the deflection angle of the protruding end 111 is greater than the first angle, or along the height direction of the electrical connector 10, when the deflection angle of the protruding end 111 is greater than the second angle, the first anti-misinsertion structure 113 and the second anti-misinsertion structure 123 are locked with each other to limit the deflection amount of the protruding end 111 relative to the slot 121, preventing the protruding end 111 from accidentally touching the board-end terminal 122 and ensuring the accurate correspondence between the positions of the board-end terminal 122 and the wire-end terminal 1122. At the same time, a plurality of terminal locking members 16 fix the wire-end terminals 1122 on the opposite side surfaces of the protruding end 111 respectively to accurately define the relative positions of the wire-end terminals 1122 and the protruding end 111.The first anti-misinsertion structure 113 and the second anti-misinsertion structure 123 define the relative positions of the protruding end 111 and the slot, and further define the relative positions of the protruding end 111 and the board-end terminal 122, thereby determining the relative positions of the wire-end terminal 1122 and the board-end terminal 122, reducing the probability of misinsertion.

[0038] Reference Figures 11 to 14 As shown, mounting grooves for the terminal locking member 16 are provided on both the upper wall and the lower wall of the protruding end 111, and the first locking member 161 is snapped into the mounting groove. The locking claws of the first locking member 161 pass through the mounting groove and are embedded into the wire-end assembly 11 to lock the wire-end terminal 1122. On the lower wall of the protruding end 111, the second locking member 162 is snapped into the mounting groove, and the locking claws of the second locking member 162 pass through the mounting groove into the wire-end assembly 11 to lock the wire-end terminal 1122, thereby fixing the wire-end terminal 1122. Wherein, the number of the first locking member 161 and the second locking member 162 can both be one or more. When the number of the first locking member 161 or the second locking member 162 is multiple, the multiple first locking members 161 or the multiple second locking members 162 can fix the wire-end terminal 1122 from different positions dispersedly, increasing the fixing flexibility and stability of the wire-end terminal 1122.

[0039] Reference Figure 1 As shown, the distance between the end of the board-end terminal 122 and the notch of the slot 121 is marked as the letter c in Figure 1 , which is greater than the depth of the protruding end 111 inserted into the slot 121 when the first anti-misinsertion structure 113 and the second anti-misinsertion structure 123 are stuck to each other, marked as the letter b in Figure 1 . When the first anti-misinsertion structure 113 and the second anti-misinsertion structure 123 are stuck to each other, the protruding end 111 reaches the limit depth of being inserted into the slot 121 at a skewed angle and cannot be inserted into the slot 121 continuously. At this time, the distance between the end of the protruding end 111 and the board-end terminal 122 is marked as the letter l in Figure 1 . It can be seen from the figure that at this time, the protruding end 111 does not touch the board-end terminal 122 due to the clamping restriction of the first anti-misinsertion structure 113 and the second anti-misinsertion structure 123, so it will not cause extrusion to the board-end terminal 122. Since the first anti-misinsertion structure 113 and the second anti-misinsertion structure 123 are clamped at this time, indicating that the insertion inclination angle is too large. After adjusting the inclination angle, the wire-end interface 112 corresponds to the board-end terminal 122, and the wire-end terminal 1122 can be inserted into the board-end terminal 122 continuously to smoothly dock the board-end terminal 122 and the wire-end interface 112 to achieve electrical connection. Ensure the accuracy of the connection, reduce the number of repeated plugging and unplugging installations, and facilitate installation.

[0040] Reference Figure 1As shown, in some of these embodiments, when the first anti-misinsertion structure 113 and the second anti-misinsertion structure 123 are stuck to each other, the distance between the end of the protruding end 111 and the board-end terminal 122 is as Figure 1 indicated by the letter l in [figure reference]. Set l to be greater than 5 mm to prevent the protruding end 111 from exceeding the insertion depth in the case of being tightly clamped due to excessive force, which can increase the stability of the anti-misinsertion effect.

[0041] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 As shown, in some of these embodiments, the first anti-misinsertion structure 113 includes a plurality of sliding grooves 1131 extending along the direction in which the protruding end 111 is inserted into the slot 121 and the outer side wall of the end of the protruding end 111; the groove walls of the sliding grooves 1131 are parallel to the outer wall of the protruding end 111 and perpendicular to the end face of the protruding end 111. The second anti-misinsertion structure 123 includes a plurality of strip-shaped protrusions 1231 and the inner side wall of the slot opening of the slot 121, and the strip-shaped protrusions 1231 correspond to the sliding grooves 1131 one by one; during the connection process of the wire-end assembly 11 and the board-end assembly 12, the strip-shaped protrusions 1231 are inserted into the sliding grooves 1131, and the side walls of the strip-shaped protrusions 1231 are parallel to the inner walls of the sliding grooves 1131, and the outer side wall of the protruding end 111 cooperates with and is parallel to the corresponding inner side wall of the slot 121. There is a first clearance fit 13 between the two side walls of the strip-shaped protrusions 1231 and the sliding grooves 1131 and between the outer wall of the protruding end 111 and the inner wall of the slot 121 in the width direction of the electrical connector 10; there is a second clearance fit 14 between the outer side wall of the end of the protruding end 111 and the inner side wall of the slot opening of the slot 121 in the height direction of the electrical connector 10; during the process of the protruding end 111 being inserted into the slot 121, when the inclination angle of the protruding end 111 in the width direction of the electrical connector 10 is greater than the first angle, the groove walls of the corresponding sliding grooves 1131 in the width direction of the electrical connector 10 and the side walls of the strip-shaped protrusions 1231 are no longer parallel, generating a relative angle. At this time, the strip-shaped protrusions 1231 are in contact with and clamped against the two side walls of the corresponding sliding grooves 1131, generating a frictional force opposite to the direction of the protruding end 111 moving towards the inside of the slot 121, preventing the protruding end 111 from continuing to move into the slot 121. Similarly, when the inclination angle of the protruding end 111 in the height direction of the electrical connector 10 is greater than the second angle, the outer side wall of the protruding end 111 in the height direction of the electrical connector 10 is in contact with and clamped against the inner side wall of the slot opening of the slot 121.

[0042] In some embodiments, by adjusting the clearance size of the first clearance fit 13 or the second clearance fit 14 between the protruding end 111 and the slot 121, the depth b of the protruding end 111 extending into the slot 121 in the clamped state can be controlled. For example, increasing the clearance size of the first clearance fit 13, along the width direction of the electrical connector 10, in the clamped state of the protruding end 111 and the slot 121, the greater the depth b of the protruding end 111 extending into the slot 121, and vice versa; increasing the clearance size of the second clearance fit 14, along the height direction of the electrical connector 10, in the clamped state of the protruding end 111 and the slot 121, the greater the depth of the protruding end 111 extending into the slot 121, and vice versa;

[0043] Reference Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in some of these embodiments, the first clearance is equal to the second clearance, and the first angle (such as the one labeled by the letter a in Figure 1 ) is equal to the second angle (such as the one labeled by the letter a1 in Figure 7 ), and both are 5° to 16°.

[0044] Reference Figure 1 , Figure 3 and Figure 4 As shown, in some of these embodiments, the outer end of the sliding groove 1131 is flush with the end of the protruding end 111, so that the groove wall of the sliding groove can extend to the end of the protruding end 111, so that the strip-shaped protrusion 1231 can first contact the sliding groove 1131. When the protruding end 111 is inserted into the slot 121 obliquely, the strip-shaped protrusion 1231 can first form an angle with the sliding groove 1131 and abut against the side wall of the sliding groove 1131, so as to reduce the length of the end of the protruding end 111 inserted obliquely into the slot 121 and reduce the installation time. One end of the strip-shaped protrusion 1231 corresponding to the sliding groove 1131 is flush with the port of the slot 121 as shown in Figure 3 , or, one end of the strip-shaped protrusion 1231 corresponding to the sliding groove 1131 protrudes outside the port of the slot 121 as shown in Figure 4 . When the strip-shaped protrusion 1231 protrudes outside the port of the slot 121, the strip-shaped protrusion 1231 contacts and cooperates with the sliding groove 1131 earlier than the slot 121, which is convenient for observing the installation and cooperation situation, and can be clamped before the protruding end 111 and the slot 121 come into contact and cooperate when the protruding end 111 is inserted into the slot 121 obliquely, improving the anti-misinsertion stability. Among them, the number of strip-shaped protrusions 1231 is multiple, and some of the strip-shaped protrusions 1231 can be set to protrude outside the port of the slot 121.

[0045] Reference Figure 2 , Figure 9 , Figure 10As shown, in some of these embodiments, the wire-end interface 112 includes a plurality of jacks 1121, and the number of board-end terminals is also a plurality and corresponds one-to-one with the plurality of jacks 1121. The plurality of jacks 1121 extend from the end face of the protruding end 111 into the protruding end 111; the extending direction of the jacks 1121 is parallel to the insertion and extraction direction of the wire-end assembly 11 and the board-end assembly 12. A wire-end terminal 1122 is provided in the jack 1121; as Figure 1 indicated by the letter H in 0, the mating length between the board-end terminal 122 and the wire-end terminal 1122 is greater than 1 mm. Optionally, the mating length between the board-end terminal 122 and the wire-end terminal 1122 is 1 mm to 4 mm. By setting the lengths of the board-end terminal 122 and the wire-end terminal 1122 and the distance between the end of the wire-end terminal 1122 and the end face of the protruding end 111, the mating dimension between the wire-end terminal 1122 and the board-end terminal 122 is controlled. For example, by setting the distance between the wire-end terminal 1122 and the end face of the protruding end 111 to be less than 2 mm, after the protruding end 111 extends into the slot 121, the board-end terminal 122 can contact and mate with the wire-end terminal 1122 after being inserted 2 mm deep into the jack 1121.

[0046] Reference Figure 2 As shown, in some of these embodiments, the number of the chutes 1131 is a plurality, and a plurality of chutes 1131 are symmetrically arranged on the outer walls on both sides of the protruding end 111 along the height direction of the protruding end 111; along the width direction of the protruding end 111, a plurality of chutes 1131 are spaced apart and distributed on the outer wall of the protruding end 111.

[0047] Reference Figure 11 As shown, in some embodiments, the number of the chutes 1131 is a plurality, and a plurality of chutes 1131 are arranged on the outer walls on both sides of the protruding end 111 in an asymmetric form along the height direction of the protruding end 111; along the width direction of the protruding end 111, a plurality of chutes 1131 are spaced apart and distributed on the outer wall of the protruding end 111. By distributing in an asymmetric form, the stress positions on the two side walls in the height direction of the protruding end 111 are staggered, which can reduce the stress intensity of the protruding end 111 and avoid damage to the protruding end 111 due to stress fatigue during multiple insertions and extractions of the wire-end assembly 11 and the board-end assembly 12.

[0048] In some embodiments, the groove width dimensions of at least some of the plurality of chutes 1131 are not equal to the groove width dimensions of other chutes 1131. Correspondingly, the width dimension of the strip-shaped convex block 1231 corresponding to the chute 1131 also changes with the change of the groove width dimension of the chute 1131.

[0049] Reference Figure 2As shown, in some of these embodiments, along the width direction of the protruding end 111, a plurality of sliding grooves 1131 are symmetrically distributed relative to the midline of the width direction of the protruding end 111, where the midline position is as Figure 2 shown by the dashed line in
