Description

Technical Field

[0001] This application relates to the technical field of connectors, and particularly 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] Many electrical connectors are applied in a vibrating environment. For example, in an automobile, it is desired to prevent two mating connectors from being disengaged due to vibration in the operating environment or having poor contact.

[0004] In the related art, an electrical connector generally includes a wire-end component (connector male head) and a board-end component (connector female head). The wire-end component is used to be inserted into the board-end component to achieve electrical connection. Among them, the board-end component includes a board-end housing, and jacks are provided on the board-end housing. The wire-end component includes a wire-end housing, and a slot is provided on the wire-end housing. A terminal holder is arranged in the slot. The board-end terminal passes through the jack and is inserted into the slot of the wire-end housing inserted into the board-end housing, and is fixedly connected with the wire-end terminal arranged in the slot of the wire-end housing through the terminal holder. A fitting portion is arranged on the insertion surface of the board-end terminal of the board-end housing, and the fitting portion protrudes outside the board-end housing to facilitate accurate insertion of the board-end terminal. A terminal holder is arranged on the wire-end housing to fix the connection between the wire-end terminal and the board-end terminal. Two limiting arms are arranged on the insertion surface between the board-end housing and the wire-end housing to ensure the accuracy of insertion. Among them, the limiting arms can play a certain guiding role. However, since the diameter of the terminals is small and the terminals are arranged densely to improve the utilization rate, they are very easy to be skewed or misaligned, resulting in the wire-end terminals not being able to contact and electrically connect with the corresponding board-end terminals. Summary of the Invention

[0005] The embodiments of the present utility model provide a connector assembly and an electrical connector to solve the problems such as inaccurate docking, poor contact, and incorrect insertion between the wire-end terminals and the board-end terminals during the installation of the connector.

[0006] A connector assembly, comprising: a board-end housing provided with a slot, a password groove structure extending inward from the slot notch on the lower sidewall of the slot; a fixed card slot structure provided on the upper sidewall of the slot; a terminal jack for inserting a board-end terminal provided on the rear sidewall of the slot; a board-end terminal, one end of which is inserted into the board-end housing through the terminal jack, and tapered card protrusions are symmetrically provided on the hole wall of the board-end terminal corresponding to the terminal jack, and the board-end terminal is clamped with the terminal jack through the tapered card protrusions; a wire-end housing inserted into the slot, and an insertion channel is formed in the wire-end housing corresponding to the board-end terminal; a slider structure is provided on the wire-end housing to fit the password groove structure; a fixed spring buckle structure is provided on the wire-end housing corresponding to the fixed card slot structure.

[0007] In one embodiment, the password groove structure includes a plurality of rectangular grooves, and at least some of the rectangular grooves have different groove widths; the slider structure includes a plurality of rectangular sliders, and the plurality of rectangular sliders are inserted into the rectangular grooves one by one.

[0008] In one embodiment, at least some of the rectangular grooves have different groove depths; the height of the rectangular slider is adapted to the groove depth of the corresponding rectangular groove.

[0009] In one embodiment, a plurality of guiding grooves are provided on the upper sidewall of the slot along the insertion direction of the wire-end housing and the board-end housing; guiding blocks are provided on the upper end face of the wire-end housing corresponding to the guiding grooves.

[0010] In one embodiment, the arrangement position of the guiding grooves is symmetrical about the board-end terminal with the arrangement position of the password grooves.

[0011] In one embodiment, the fixed card slot is arranged at the middle position among the plurality of guiding grooves and is fixed in cooperation with the fixed spring buckle structure. In a vibration environment, the guiding grooves on both sides can further increase the connection stability between the fixed spring buckle structure and the fixed card slot structure.

[0012] In some embodiments, the fixed card slot structure may not be arranged at the middle position of the guiding grooves and may be arranged at any position of the connection between the board-end housing and the wire-end housing, including being arranged at the middle position of the password groove structure.

[0013] In one embodiment, the transverse distribution length of the password groove along the connector housing corresponds to the distribution length of the terminals.

[0014] In one embodiment, the outer side surface of the tapered card protrusion is inclined outward along the insertion direction of the board-end terminal.

[0015] In one of the embodiments, the board-end terminal and the terminal jack are in clearance fit, and the bilateral clearance is less than 0.5 mm. The outward protruding height of the conical clamping protrusion is 0.8 to 1.5 mm.

[0016] An electrical connector includes the connector assembly described in the above embodiment. The insertion channel of the wire-end housing is used to install the wire-end terminal, and the board-end terminal is inserted into the insertion channel to be in contact connection with the wire-end terminal.

[0017] In some embodiments, the password slot is formed by a plurality of rectangular columns arranged at intervals, and a chute is formed between two adjacent rectangular sliders in the slider structure. The chute and the rectangular column are in cooperation, and the cooperation between the password slot and the slider structure forms a combined locking structure.

[0018] In some embodiments, the chute has the same structure as the password slot, and the rectangular column has the same structure as the rectangular slider.

[0019] In some embodiments, the rectangular slider includes a positioning block. The height of the positioning block is greater than the height of the other rectangular sliders. The lower edge of one end of the positioning block corresponding to the insertion direction of the board-end housing and the wire-end housing protrudes from the wire-end housing to preferentially contact the password slot structure of the board-end housing. To not affect the adaptation position of the wire-end housing and the board-end housing, one end of the positioning block corresponding to the direction of insertion into the board-end housing is an inclined surface, where the lower edge of the positioning block extends toward the direction of insertion into the board-end housing, and the upper edge of the positioning block is flush with the end of the wire-end housing. The board-end housing is provided with an avoidance space corresponding to the password slot structure of the positioning block to eliminate the interference of the positioning block on the relative position of the board-end housing and the wire-end housing.

[0020] In some embodiments, the fixed card slot structure is provided with a baffle plate facing the inside of the board-end housing at the slot opening of the slot of the board-end housing. After the board-end housing and the wire-end housing are inserted and connected, the fixed snap structure is snapped into the fixed card slot structure, and the baffle plate stops at the slot opening of the board-end housing to prevent the fixed snap structure from coming out, further improving the connection stability of the electrical connector.

[0021] The above connector assembly and electrical connector have at least the following beneficial effects:

[0022] The wire-end housing is inserted and connected to the board-end housing. The relative positions of the wire-end housing and the board-end housing are accurately determined through the cooperation of the password groove structure and the slider structure. After the wire-end housing and the board-end housing are installed in place, the positions of the wire-end housing and the board-end housing are fixed through the fixed card slot and the fixed snap. The relative position of the board-end terminal and the board-end housing is fixed by the extrusion fit between the conical convex and the inner wall of the terminal jack, thereby determining the relative position of the board-end terminal and the wire-end housing, enabling the board-end terminal to be accurately inserted into the insertion channel to connect with the wire-end terminal, improving the installation stability of the electrical connector, and at the same time enhancing the anti-vibration performance of the electrical connector.

[0038] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0039] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be a middle element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a middle element at the same time. The terms "vertical", "horizontal", "left",

[0040] "right" and similar expressions are only for the purpose of illustration. 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 the present invention belongs. The terms used herein in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0041] Refer to Figures 1 to 12As shown, the utility model discloses a connector assembly 11, which includes a board-end housing 11a, board-end terminals 11b, and a wire-end housing 11c. The board-end housing 11a has a rectangular profile with an opening on the side. One end of the wire-end housing 11c is inserted into the board-end housing 11a for plug-in connection. Corresponding to the plug-in structure of the board-end housing 11a and the wire-end housing 11c, the board-end housing 11a is provided with a slot 11a1 that extends inward from the side opening. The lower sidewall of the slot 11a1 is provided with a password slot structure 11a2 that extends inward from the slot opening of the slot 11a1. The password slot structure 11a2 is composed of a combination of multiple slots with different slot widths, different slot depths, or both different slot widths and slot depths. Among them, different combinations of slot width dimensions (or slot depth dimensions) form the password of the password slot structure. The number of slots in the password slot structure 11a2 constitutes the number of password digits. The more slots there are, the more password digits are formed, and thus the stronger the anti-misconnection function. The slider structure 11c2 cooperates with the password slot structure 11a2 to jointly form an anti-misconnection plug structure.

[0042] Exemplarily, the password slot structure 11a2 is set to five rectangular slots, and the slot widths of the five rectangular slots are 5 mm, 6 mm, 7 mm, 9 mm, and 10 mm respectively. The configured slider structure 11c2 includes five rectangular sliders, and the width dimensions of the rectangular sliders corresponding to the five rectangular slots are respectively adapted to 5 mm, 6 mm, 7 mm, 9 mm, and 10 mm. During the plug-in process of the board-end housing 11a and the wire-end housing 11c, each rectangular slider can only be inserted into the rectangular slot with a corresponding size, which can play a role in accurate plug-in. At the same time, the password slot structure 11a2 can also adjust the plug-in decryption degree by setting the fit tolerance between the rectangular slot and the rectangular slider to adjust the installation difficulty.

[0043] The wire-end housing 11c is adapted to the password slot structure 11a2, and is provided with a slider structure 11c2. The slider structure 11c2 is tightly fitted and inserted into the password slot structure 11a2. Corresponding to the password parameters of different password slots, the slider structure 11c2 is set with corresponding fitting parameters, which can accurately prevent misinsertion. The upper side wall of the slot 11a1 is provided with a fixed card slot structure 11a3, and the wire-end housing 11c is provided with a fixed snap structure 11c3 corresponding to the fixed card slot structure 11a3. After the board-end housing 11a and the wire-end housing 11c are correctly inserted, the fixed snap structure 11c3 pops up upwards and is clamped into the fixed card slot structure 11a3, locking the relative positions of the wire-end housing 11c and the board-end housing 11a, and further strengthening the connection between the wire-end housing 11c and the board-end housing 11a. The rear side wall of the slot 11a1 is provided with a terminal jack 11a4 for inserting the board-end terminal 11b. One end of the board-end terminal 11b is inserted into the board-end housing 11a through the terminal jack 11a4. The insertion direction of the board-end terminal 11b into the board-end housing 11a is parallel to the extension direction of the password slot. The terminal jack 11a4 is a strip-shaped hole, which extends inward from the rear side wall of the board-end housing 11a, and the extension direction is the same as the insertion direction of the board-end terminal 11b in the board-end housing 11a. The board-end terminal 11b is symmetrically provided with tapered card protrusions 11b1 on the hole walls corresponding to the terminal jack 11a4. The tapered card protrusions 11b1 protrude outward on both sides of the board-end terminal 11b. The board-end terminal 11b is clamped with the terminal jack 11a4 through the tapered card protrusions 11b1. The board-end terminal 11b is made of a rigid material and is clamped with the terminal jack 11a4 through the tapered card protrusions 11b1, so that the relative position of the board-end terminal 11b and the board-end housing 11a can be accurately fixed. The wire-end housing 11c is formed with an insertion channel 11c1 corresponding to the board-end terminal 11b. During the insertion process of the wire-end housing 11c and the board-end housing 11a, the wire-end housing 11c and the board-end housing 11a can be inserted along an accurate track through the cooperation of the password slot and the slider structure 11c2. The board-end terminal 11b maintains an accurate relative position with the board-end housing 11a through the tapered card protrusion 11b1 structure. In this way, the board-end terminal 11b can be accurately inserted into the insertion channel 11c1 of the wire-end housing 11c. In the actual application process, a wire-end terminal and a terminal fixer are fixedly arranged in the insertion channel 11c1 of the wire-end housing 11c. The board-end terminal 11b enters the insertion channel 11c1 of the wire-end terminal along an accurate track and is in contact connection with the wire-end terminal, increasing the connection accuracy and stability of the electrical connector 10.

[0044] Reference Figures 1 to 6As shown, in one embodiment, the password slot structure 11a2 includes a plurality of rectangular slots, and at least some of the rectangular slots have different slot widths. By matching different slot widths with different slider widths, incorrect insertion is ensured to be avoided. At the same time, the fitting error between the rectangular slot and the rectangular slider is smaller than the allowable fitting error between the board-end terminal 11b and the insertion channel 11c1. The slider structure 11c2 includes a plurality of rectangular sliders, and the plurality of rectangular sliders are inserted into the rectangular slots one by one. The outer end of the rectangular slider is flush with or extends beyond the end of the end of the wire-end housing 11c inserted into the board-end housing 11a, so that the contact fit between the password slot and the slider structure 11c2 precedes the contact fit between the wire-end housing 11c and the board-end housing 11a, thereby reducing the probability of incorrect insertion operation.

[0045] In some embodiments, the password slot structure 11a2 is formed by a plurality of rectangular columns arranged at intervals, and a chute is formed between two adjacent rectangular sliders in the slider structure 11c2. The chute and the rectangular column form a fit, and together with the fit between the password slot and the slider structure 11c2, a combined locking structure is formed.

[0046] In some embodiments, the chute is the same as the password slot structure 11a2, and the structure of the rectangular column is the same as that of the rectangular slider.

[0047] Reference Figure 12 As shown, in some embodiments, the slider structure 11c2 includes a positioning block 11c5. The height of the positioning block 11c5 is greater than the height of other rectangular sliders. The lower edge of one end of the positioning block 11c5 corresponding to the insertion direction of the board-end housing 11a and the wire-end housing 11c protrudes from the wire-end housing 11c to preferentially contact the password slot of the board-end housing 11a. To avoid affecting the fitting position of the wire-end housing 11c and the board-end housing 11a, one end of the positioning block 11c5 corresponding to the direction of insertion into the board-end housing 11a is an inclined surface, wherein the lower edge of the positioning block 11c5 extends toward the direction of insertion into the board-end housing 11a, and the upper edge of the positioning block 11c5 is flush with the end of the wire-end housing 11c. The board-end housing 11a is provided with an avoidance space corresponding to the password slot of the positioning block 11c5 to eliminate the interference of the positioning block 11c5 on the relative position of the board-end housing 11a and the wire-end housing 11c.

[0048] Reference Figures 1 to 5 As shown, in one embodiment, at least some of the rectangular slots have different slot depths. Among them, the depth of the rectangular slot can be defined by setting the height dimension of the slot edge. The height of the rectangular slider is adapted to the slot depth of the corresponding rectangular slot. The password method of the password slot includes setting the slot width and slot depth of the rectangular slot. Different slot depths correspond to different heights of the rectangular sliders, and different slot widths correspond to different widths of the rectangular sliders, further increasing the connection accuracy between the board-end housing 11a and the wire-end housing 11c.

[0049] Reference Figure 1 、 Figure 5 、 Figure 7 、Figure 8 , Figure 9 As shown in Figure 9 , in one embodiment, along the upper side wall of the slot 11a1, there are a plurality of guiding grooves 11a5 arranged along the insertion direction of the wire end housing 11c and the board end housing 11a. The extending direction of the guiding grooves 11a5 is the insertion direction of the wire end housing 11c and the board end housing 11a. The outer ends of the guiding grooves 11a5 are aligned with the slot openings of the slot 11a1 of the board end housing 11a to facilitate the insertion of the wire end housing 11c and the board end housing 11a. Corresponding to the guiding grooves 11a5, guiding blocks 11c4 are provided on the upper end face of the wire end housing 11c. The guiding grooves 11a5 include rectangular grooves, and the guiding blocks 11c4 are rectangular blocks corresponding to the guiding grooves 11a5. The outer ends of the guiding blocks 11c4 are aligned with or extend beyond the end of the wire end housing 11c inserted into the board end housing 11a.

[0050] Refer to Figures 1 to 5 As shown in Figures 1 to 5 , in one embodiment, the arrangement positions of the guiding grooves 11a5 and the password grooves are symmetric about the board end terminal 11b. The board end housing 11a has a rectangular profile. The board end terminal 11b is inserted into the board end housing 11a from the rear side wall of the board end housing 11a, and the insertion direction of the board end terminal 11b is perpendicular to the rear side wall of the board end housing 11a and parallel to the side wall of the board end housing 11a. Above the board end terminal 11b is the upper inner wall of the board end housing 11a, and the guiding grooves 11a5 are provided on the inner upper side wall of the board end housing 11a. The password grooves are provided on the lower side wall of the board end housing 11a. The extending direction of the guiding grooves 11a5 is the same as the extending direction of the password grooves and the insertion direction of the board end terminal 11b. The board end housing 11a is made of an integrally formed rigid material. By providing the guiding grooves 11a5 above the board end terminal 11b and the password groove structure 11a2 below, the relative positions of the board end housing 11a and the wire end housing 11c can be determined simultaneously on both sides of the board end terminal 11b, and the relative position of the board end terminal 11b of the board end housing 11a and the insertion channel 11c1 of the wire end housing 11c can be determined more accurately. At the same time, in the case of vibration during use, the guiding grooves 11a5 above the board end terminal 11b and the password grooves below the board end terminal 11b can fix the cooperation between the board end terminal 11b and the wire end terminal on both sides of the board end terminal 11b, which can strengthen the connection stability between the board end terminal 11b and the wire end terminal.

[0051] Refer to Figures 1 to 5 As shown in Figures 1 to 5 , in one embodiment, the guiding grooves 11a5 are symmetrically arranged on both sides of the fixed card slot structure 11a3 along the transverse direction of the connector housing. The fixed card slot is arranged at the middle position of a plurality of guiding grooves 11a5 and is fixed in cooperation with the fixed snap structure 11c3. In a vibrating environment, the guiding grooves 11a5 on both sides can further increase the connection stability between the fixed snap structure 11c3 and the fixed card slot structure.

[0052] In some embodiments, the fixed card slot structure 11a3 may not be provided at the middle position of the guide slot 11a5, and may be provided at any position of the connection between the board-end housing 11a and the wire-end housing 11c, including the middle position of the password slot structure 11a2.

[0053] Refer to Figure 9 As shown, the fixed card slot structure 11a3 is provided with a baffle facing the inside of the board-end housing 11a at the notch of the slot 11a1 corresponding to the board-end housing 11a. After the board-end housing 11a and the wire-end housing 11c are plugged together, the fixed snap structure 11c3 is snapped into the fixed card slot structure 11a3, and the baffle stops at the notch of the board-end housing 11a to prevent the fixed snap structure 11c3 from coming out, further improving the connection stability of the electrical connector 10.

[0054] Refer to Figures 1 to 6 As shown, in one embodiment, the distribution length of the password slot structure 11a2 along the transverse direction of the electrical connector 10 corresponds to the distribution length of the terminals. The password slot is provided below the board-end terminals 11b. The board-end terminals 11b are distributed transversely and are arranged in multiple rows in the up-down direction. The password slot is provided below the board-end terminals 11b. Along the transverse direction, the two ends of the password slot correspond to the two ends of the board-end terminals 11b, or extend to the outside of the two ends of the board-end terminals 11b to ensure the limitation of the positions of all the board-end terminals 11b.

[0055] Refer to Figures 1 to 4 As shown, in one embodiment, the outer side surface of the tapered convex 11b1 inclines outward along the insertion direction of the board-end terminal 11b. The tapered outer side surface of the tapered convex 11b1 inclines outward from the insertion end to the tail end of the board-end terminal 11b. During the process of inserting the board-end terminal 11b into the terminal jack 11a4, the tapered convex 11b1 is continuously inserted into the terminal jack 11a4 from the small end of the taper to the large end of the taper. When the large end of the taper is inserted into the terminal jack 11a4, the large end of the taper is stuck with the hole wall of the terminal jack 11a4. Since the tapered convex 11b1 is a symmetric structure, the accuracy of the position of the board-end terminal 11b can be guaranteed.

[0056] Refer to Figures 1 to 4As shown, in one of the embodiments, the board-end terminal 11b and the terminal jack 11a4 are in clearance fit, and the bilateral clearance is less than 0.5 mm. The height of the tapered convex 11b1 protruding outward is 0.8 to 1.5 mm. The terminal jack 11a4 and the board-end terminal 11b are in clearance fit, but the bilateral clearance is set to be less than 0.5 mm. The tapered convex 11b1 protrudes symmetrically outward on both sides of the board-end terminal 11b, enabling the board-end terminal 11b to be inserted into the center of the terminal jack 11a4, so that the unilateral clearance between the board-end terminal 11b and the inner wall of the terminal jack 11a4 remains less than 0.25 mm. The height of the tapered convex 11b1 protruding outward is 0.8 mm to 1.5 mm, making the tapered convex 11b1 and the terminal jack 11a4 in interference fit to fix the relative position of the board-end terminal 11b and the board-end housing 11a.

[0057] In some embodiments, the tapered convex 11b1 is an elastic convex. The elastic convex can move towards the direction close to the board-end terminal when being pressed, and can bounce towards the direction away from the board-end terminal when the pressing is released. Among them, the elastic convex can be a rigid part made of an elastic material or connected to the board-end terminal through an elastic member such as a spring.

[0058] Reference Figures 1 to 11 As shown, the present utility model discloses an electrical connector 10, including the connector assembly 11 of the above embodiment. The insertion channel 11c1 of the wire-end housing 11c is used to install the wire-end terminal, and the board-end terminal 11b is inserted into the insertion channel 11c1 to be in contact connection with the wire-end terminal.

[0059] The electrical connection includes a board-end housing 11a and a wire-end housing 11c. The board-end housing 11a and the wire-end housing 11c are plugged in according to the above embodiment. The wire-end housing 11c and the board-end housing 11a are plugged and connected. The relative position of the wire-end housing 11c and the board-end housing 11a is accurately determined through the cooperation of the password groove structure 11a2 and the slider structure 11c2. After the wire-end housing 11c and the board-end housing 11a are installed in place, the positions of the wire-end housing 11c and the board-end housing 11a are fixed through the fixing card slot and the fixing snap. By using the extrusion fit between the tapered convex 11b1 and the inner wall of the terminal jack 11a4, the relative position of the board-end terminal 11b and the board-end housing 11a is fixed, thereby determining the relative position of the board-end terminal 11b and the wire-end housing 11c, enabling the board-end terminal 11b to be accurately inserted into the insertion channel 11c1 to be connected with the wire-end terminal, improving the installation stability of the electrical connector 10, and at the same time improving the anti-vibration performance of the electrical connector 10.

[0060] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, the above embodiments

[0061] All possible combinations of the various technical features are described. However, as long as there are no contradictions in the combinations of these technical features, they should all be considered to be within the scope described in this specification.

[0062] The above-described embodiments only express several implementation manners of the present utility model. The description is relatively specific and detailed, but

[0063] it should not be construed as a limitation on the scope of the utility model patent for this reason. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
