[0037] The connector 2 is an electronic component used to connect devices for signal transmission, and usually has a wire harness inside. Due to the relatively weak strength of the wire harness itself, and for the consideration of protecting the connector 2 and the wire harness, injection molding treatment needs to be carried out on its exterior. To separate the injection molding material from the holes of the connector 2 and avoid the injection molding material affecting the internal structure of the connector 2 and the wire harness, a connector protection head 1 needs to be installed at one end where the connector 2 is connected to the wire harness.

[0038] Referring to Figure 1 - Figure 2 , the connector assembly of the embodiment of the present utility model includes a connector 2 and a connector protection head 1. Among them, the connector 2 includes a main body 21 and a raised edge 22, and the raised edge 22 is arranged at one end of the main body 21. The two protection parts of the connector protection head 1 are clamped and sleeved on the raised edge 22 for protecting the connector 2 and blocking the injection molding material to ensure the product performance.

[0039] Referring to Figure 3 - Figure 6 , the connector protection head 1 of the embodiment of the present utility model includes two protection parts, and the two protection parts are clamped with each other and installed on the raised edge 22 outside the holes of the connector 2 to realize the separation between the holes of the connector 2 and the external injection molding material, so that the injection molding process does not affect the internal structure of the connector 2 and the wire harness and ensures the product performance. Each protection part includes a covering structure, a first hook 15 and a second hook 16. Among them, the covering structure is used to block the adhesive material and install the protection part on the raised edge 22 of the connector 2. The first hook 15 of one protection part is used to cooperate with the second hook 16 of another protection part for clamping, so that the connector protection head 1 can be fixed in the vertical direction to ensure its function of blocking the adhesive material and realizing separation.

[0040] Referring to Figure 2 , the covering structure includes a first baffle 11, a covering part 12 and a second baffle 13 which are connected in sequence to form a covering groove 14. Among them, the first baffle 11 is located at the front end and is used to block one end of the holes of the connector 2 to prevent the adhesive material from entering.

[0041] Referring to Figure 2 、 Figure 4 , the second baffle 13 is located at the rear end, and the two second baffles 13 enclose a profiling groove. When the protection part is installed on the connector 2, the second baffle 13 contacts the rear end of the raised edge 22 of the connector 2 and is in profiling cooperation with the connection line between the raised edge 22 and the main body 21 of the connector 2 to realize better fixation. The covering part 12 connects the first baffle 11 and the second baffle 13, and its two ends in the axial direction of the connector 2 are respectively connected to the outermost edges of the first baffle 11 and the second baffle 13. The first baffle 11 and the second baffle 13 are arranged in parallel, and the first baffle 11, the covering part 12 and the second baffle 13 cooperate to be able to fix the protection part in the axial direction of the connector 2.

[0042] Reference Figure 2 - Figure 4 , at least one wire groove 111 with an opening is provided on the first baffle 11, and the two first baffles 11 are connected so that the corresponding wire grooves 111 are connected to form a wire hole, which is used to avoid the wire harness connected to the connector 2. According to the actual situation, the number of wire grooves 111 can be one, two or more. The shape of the wire groove 111 changes with the outer contour of the wire harness. For a single protective member, the opening area of ​​its wire groove 111 is half of the cross-sectional area of ​​the wire harness. For example, when the outer contour of the wire harness is circular, the shape of the wire groove 111 is semicircular. The first baffle 11, the covering portion 12 and the second baffle 13 form a semi-circular covering groove 14, which is used to accommodate the raised edge 22 of the connector 2 to achieve the positioning of the connector. The covering groove 14 has openings at both ends for matching with the covering groove 14 of another protective member. For a complete connector protective head 1, the covering structures of the two protective parts are arranged opposite to each other, and the two ends of the two covering grooves 14 are connected to form an annular limiting groove to better accommodate the raised edge 22 and achieve stable installation.

[0043] Reference Figure 4 - Figure 5 , the first hook 15 and the second hook 16 are respectively protruded at the two ends of the second baffle 13, and the second hook 16 on one protective member is correspondingly snap-connected with the first hook 15 on the other protective member. An avoidance groove 161 is formed between the second hook 16 and the second baffle 13, which is used to avoid the structure on the other protective member. When the two protective members are engaged, the first hook 15 and the second hook 16 are engaged at the rear end of the protective member to fix the protective member in the vertical direction. According to actual conditions, the first hook 15 and the second hook 16 can have guide surfaces with the same inclined direction, and the first hook 15 and the second hook 16 are elastic hooks. Therefore, when the two protective members are engaged, the first hook 15 of one protective member and the second hook 16 of the other protective member can be slidably snap-connected through the cooperation of the two guide surfaces.

[0044] Specifically, refer to Figure 4 When engaging, the guide surfaces of the first hook 15 and the second hook 16 first contact and slide along the guide direction. Since the first hook 15 and the second hook 16 are elastic, the squeezed first hook 15 and the second hook 16 are bent in the direction away from the guide surface. When sliding until the hook-shaped parts are staggered, the two guide surfaces are separated, and there is no squeezing between the first hook 15 and the second hook 16. At this time, the first hook 15 and the second hook 16 are elastically rebounded, so that they are in a mutually buckled state, and the two protective parts are fixed in the vertical direction.

[0045] In some embodiments, reference Figure 6 , Figure 7 , Figure 8, the protective member further includes a third hook 17 and a fourth hook 18 for further fixing between two protective members. The third hook 17 and the fourth hook 18 are disposed at the front end of the first baffle 11 and on both sides of the wire groove 111 respectively. The third hook 17 and the fourth hook 18 extend in opposite directions, and the third hook 17 extends downward out of the first baffle 11. That is to say, the third hook 17 and the fourth hook 18 extend vertically upward and downward. When engaging, the third hook 17 on one protective member is correspondingly snap-connected to the fourth hook 18 on another protective member, so as to fix the connector protection head 1 in a direction perpendicular to the axis of the connector 2. According to the actual situation, the third hook 17 and the fourth hook 18 may have guide surfaces with the same inclination direction, and the third hook 17 and the fourth hook 18 are elastic hooks. Therefore, when the two protective members are engaged, the third hook 17 of one protective member and the fourth hook 18 of another protective member can achieve a sliding snap connection through the cooperation of the two guide surfaces.

[0046] Specifically, referring to Figure 8 , when engaging, the guide surfaces of the third hook 17 and the fourth hook 18 come into contact first and slide along the guiding direction. Since the third hook 17 and the fourth hook 18 are elastic, the third hook 17 and the fourth hook 18 being squeezed bend respectively in the direction away from their guide surfaces. When sliding to the point where their hook-shaped parts are staggered, the two guide surfaces are separated, and there is no longer extrusion between the third hook 17 and the fourth hook 18. At this time, due to elastic rebound, the third hook 17 and the fourth hook 18 form a state of mutual engagement, so as to fix the two protective members in the vertical direction.

[0047] In some embodiments, referring to Figure 3 , Figure 5 - Figure 6 , the protective member further includes a sealing portion 113 for further enhancing the barrier effect of the protective member and preventing the rubber material from entering the interior of the connector 2 through the gap between the two protective members. The sealing portion 113 is wrapped and connected to one end surface of the wrapping structure and extends downward to the outside of the wrapping structure. For a single protective member, the third hook 17 and the first hook 15 are disposed on the sealing portion 113, and the third hook 17 and the first hook 15 are disposed at both ends of the sealing portion 113. When the two protective members are engaged, the sealing portion 113 on one protective member wraps around the outside of the other end of the wrapping structure of another protective member. That is to say, when the two protective members are engaged, referring to Figure 3 - Figure 4, the edges on the opposite sides of the first baffles 11 of the two protective parts are in contact, and the two sealing parts 113 cover the front of the gap formed by the connection of the two first baffles 11 to block the gap formed by the two first baffles 11. During the injection molding process, when the rubber material enters the connector protection head, due to the blocking of the sealing part, the rubber material needs to first enter the gap between the sealing part and the first baffle in the vertical direction, and then enter the gap between the two first baffles in the axial direction of the connector. That is to say, the setting of the sealing part increases the difficulty of the rubber material entering, effectively strengthens the blocking effect on the rubber material, and avoids the influence of the rubber material on the internal structure and wiring harness of the connector 2 during the injection molding process. At the same time, the avoidance groove 161 provided between the second hook 16 and the second baffle 13 can avoid the sealing part 113 on another protective part, so that after the engagement is formed, the end of the sealing part 113 of another protective part can be caught in the avoidance groove 161 of the current protective part. Since the hook-shaped part of the second hook 16 of the current protective part is arranged on the side far from the second baffle 13, the hook-shaped part of the second hook 16 and the second baffle 13 cover the sealing part 113 of another protective part, providing reinforcement for the fixation of the connector protection head 1 in the axial direction of the connector 2.

[0048] In some embodiments, referring to Figure 3 , Figure 6 , the connector protection head 1 further includes a protection block 112 for protecting the wiring harness. The protection block 112 protrudes from the front end face of the first baffle 11, and the wire groove 111 runs through the protection block 112 and the first baffle 11 from front to back, avoiding the situation that due to the relatively thin first baffle 11, it cannot provide effective support, making it easier for the wiring harness to form a fold angle on the outside of the part where the wiring harness enters the connector 2 and the connector protection head 1, resulting in wiring harness wear and internal wire breakage. The protection block 112 can make the wire hole formed by the wire groove 111 have a certain length, and the wiring harness located in the wire hole can be protected and will not be bent. At the same time, since the wiring harness in the wire hole has a certain length, for the wiring harness outside the wire hole, it can be more supported by the strength of the rubber sleeve wrapped around the wiring harness, avoiding the influence of the injection molding process on the wiring harness and ensuring the product performance.

[0049] When installing the connector protection head 1, referring to Figure 1 - Figure 4, the two protective parts are engaged in the vertical direction to wrap the convex flange 22. Among them, the first baffle 11 and the second baffle 13 are respectively arranged at the front end and the rear end of the convex flange 22 to fix the connector protection head 1 in the axial direction of the connector 2. Two sets of snap connections composed of the first hook 15 and the second hook 16 are located at the rear end of the convex flange 22 to provide fixation for the connector protection head 1 in the vertical direction. Two sets of snap connections composed of the third hook 17 and the fourth hook 18 are located at the front end of the convex flange 22 to provide fixation for the connector protection head 1 in the vertical direction. The two protective parts cooperate to form two sets of snap connections, which can avoid the problem that when only one side is fixed, the two protective parts will separate around the fixed side to form a gap, resulting in the entry of the rubber material, and effectively protect the connector 2.

[0050] At the same time, the snap connection at the front end of the convex flange 22 cooperates with the snap connection at the rear end of the convex flange 22 to achieve fixation in the axial direction of the connector 2. Since the connector protection head 1 has a certain length in the axial direction of the connector 2, when it is fixed only on one side in its axial direction, the two protective parts will turn over around the fixed side to form a gap, allowing the injection plastic material to enter the connector 2. Through the cooperation of the snap connections at the front end and the rear end of the convex flange 22 of the connector protection head 1, the injection plastic material is blocked, and the problem of the injection plastic material entering caused by the gap in the connector protection head 1 is avoided, so that the injection molding process does not affect the internal structure and wiring harness of the connector 2, ensuring the product performance.

[0051] The embodiment of the present application provides a connector protection head and a connector assembly. The connector protection head includes two protective parts, and each protective part includes a wrapping structure, a first hook and a second hook. Among them, the wrapping structure includes a first baffle, a wrapping part and a second baffle that are sequentially connected to form a wrapping groove. The first baffle and the second baffle are arranged in parallel, and both ends of the wrapping groove have openings. The first hook and the second hook respectively protrude from both ends of the second baffle. The first baffle can separate the connector from the injection plastic material, avoid the rubber material from entering the connector interior, and protect the product. The first baffle and the second baffle are connected through the wrapping structure, so that the connector protection head composed of the protective parts can be fixed in the axial direction of the connector. The first hook and the second hook cooperate to fix the connector protection head in the vertical direction. The wrapping groove wraps the convex flange of the connector. When the two protective parts are engaged, the connector protection head can be effectively fixed on the connector, achieving effective protection, separating the injection plastic material from the connector holes, and making the injection molding process not affect the internal structure and wiring harness of the connector, ensuring the product performance.

[0052] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
