Description

Technical Field

[0001] The utility model belongs to the technical field of automotive and engine electronic control wire harness accessories, and particularly relates to a fixed housing for a wire harness connector with a glue injection hole. Background Art

[0002] As the neural network of an automobile, the automotive wire harness plays the role of power distribution and signal transmission. The stable transmission of signals is crucial for the automobile to exhibit good handling and safety performance.

[0003] Water ingress at the wire harness plug, that is, the connector part, is a common failure mode that causes corrosion and poor contact of the automotive wire harness, resulting in unstable signals. Currently, the connectors used in some automotive and engine wire harnesses cannot adapt to various complex working conditions. Water containing various impurities and having different acidities or alkalinities easily penetrates into the interior of the mating part of the connector through the gaps between the multi-strand wires, causing electrical connection and corrosion at the contact part, seriously affecting the normal performance of the automobile. Therefore, it is particularly important to improve the waterproof performance of the plug-in. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the utility model provides a fixed housing for a wire harness connector with a glue injection hole, which has the advantages of simple structure and convenient use, and solves the problems mentioned in the above background art.

[0005] The utility model provides the following technical solution: a fixed housing for a wire harness connector with a glue injection hole, one side of the left housing and the right housing is connected by a connecting piece and can rotate relatively. When the left housing and the right housing are closed, they enclose a cavity. The left housing and the right housing are respectively provided with locking parts for locking the left and right housings when closed. One end of the cavity is provided with a plurality of limiting strips for connecting a corrugated pipe, and the other end of the cavity is provided with a plurality of limiting protrusions for connecting a connector. The left housing and the right housing are provided with through glue injection holes, and the axis of the glue injection hole is not parallel to the axis of the first cavity.

[0006] It further includes a glue injection hole plug. The glue injection hole plug includes an end part and a plug part. The outer diameter of the plug part and the inner diameter of the glue injection hole are in interference fit. The plug part can be a threaded structure, which is more convenient to rotate and screw into the glue injection hole while ensuring sealing through interference fit. The glue injection hole plug is one of the sealing means for plugging the glue injection hole.

[0007] On each side of the opening and closing sides of the left protective shell and the right protective shell, there is a positioning plate, and corresponding fixing holes are provided on the positioning plate. The fixing member passes through the fixing holes to connect the positioning plate with the corresponding structures of the vehicle and the engine. After installation, the fixing holes on the left protective shell and the right protective shell coincide. The fixing member can be a cable tie or a screw. The cable tie passes through the fixing hole and is fixed to the corresponding position of the vehicle and the engine, or the screw passes through the fixing hole and is fixed to the corresponding position of the vehicle and the engine. Through the designed positioning plate, fixing holes and fixing members, it is convenient to fix the connector at the corresponding position of the vehicle and the engine and determine its position.

[0008] The connecting member is a connecting piece, and the connecting piece is V-shaped. The connecting piece is made of a flexible material, such as rubber or plastic. The connecting piece can deform as the left protective shell and the right protective shell rotate relative to each other, or in other words, in different opening or closing states. When the left protective shell and the right protective shell are opened, the connecting piece expands into a V shape. When the left protective shell and the right protective shell are closed, the two inner surfaces of the V shape of the connecting piece abut against each other.

[0009] Between the lowermost limiting strip that closely cooperates with the wave crest of the corrugated pipe and the uppermost limiting convex block that closely cooperates with the connector is a first cavity, which defines the maximum space for injecting glue, and the glue will not continue to flow towards the corrugated pipe or the connector. At least one side of the connecting piece is provided with a retaining piece, and the length of the retaining piece along the radial direction of the protective shell is the height between the lowermost limiting strip and the uppermost limiting convex block. That is, when the left protective shell and the right protective shell are closed, the upper surface of the retaining piece abuts against the lowermost limiting strip, and the lower surface abuts against the uppermost limiting convex block, so as to prevent the glue from flowing into the inner surfaces that abut against each other between the connecting pieces when the left protective shell and the right protective shell are closed and glue is injected.

[0010] The locking members are a buckle and a clamping block that cooperate with each other, and are respectively provided on the left protective shell and the right protective shell. Preferably, two sets of locking members are provided, near the upper and lower openings of the protective shell, and the clamping is firm. One set of locking members refers to a buckle and a cooperating clamping block.

[0011] The area where the limiting strip and the limiting convex block are located is the connecting part. A clamping ring is provided on one of the protective shells within the horizontal range corresponding to the connecting part. The clamping ring is a non-closed ring shape, and a clamping ring groove is provided at the corresponding position on the other protective shell. When the left protective shell and the right protective shell are closed, the clamping ring groove is used to accommodate the clamping ring. At least two sets of clamping rings are provided. One set of clamping rings is provided in the upper connecting part, that is, the connecting part area where the limiting strip is located. One set of clamping rings is on the left and right side walls of the left protective shell.

[0012] The inner diameter sizes of the multiple limiting strips become smaller as they get closer to the glue injection hole. This design is for the limiting strips to fit corrugated pipes of different sizes. Within the adaptable range, as the limiting strips that are connected and matched get closer to the glue injection hole, the sizes of the wave crests and wave troughs of the corrugated pipe gradually become smaller.

[0013] The glue injection holes on the left protective shell and the right protective shell correspond to each other in position. When the two are closed, the axes of the glue injection holes are on the same straight line. Two glue injection holes are designed, which are respectively located on the left protective shell and the right protective shell. One consideration is that when using one glue injection hole for glue injection, the other glue injection hole is convenient for exhaust. Another consideration is that if there is only one glue injection hole, it cannot ensure that the area to be filled between the guides and between the wire and the connector is filled with glue. When this situation occurs, glue injection is also required from both sides respectively, and two glue injection holes can ensure the glue injection effect.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] A fixed protective shell of a wire harness connector with glue injection holes designed by the utility model, after the protective shell, the corrugated pipe and the connector are installed and adapted and closed, glue is injected into the protective shell through the glue injection holes to complete the sealing between the wires and between the wire and the tail of the connector. The cost is relatively low, but the actual effect is very good, avoiding moisture from entering the mating part of the connector through the gap between the multi-strand wire and the tail of the connector; the design of the baffle on the connecting piece, as well as the design of the limiting strip and the limiting convex block, cooperate to limit the glue injection area and avoid glue leakage; the added positioning plate, fixing holes and fixing parts are used for the installation of the connector on the vehicle and the engine, which is convenient for determining the position; the cooperation of the snap ring and the snap ring groove can further limit the position of the corrugated pipe, and the locking part is used for locking when the protective shell is closed.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Specific embodiment 1: Please refer to Figures 1-3 , a fixed protective shell for a wire harness connector with a glue injection hole. One side of the left protective shell 1 and the right protective shell 2 is connected by a connecting piece and can rotate relative to each other. This relative rotation occurs during the process of converting between the open and closed states of the two. When the left protective shell 1 and the right protective shell 2 are closed, they enclose a cavity. The left protective shell 1 and the right protective shell 2 are respectively provided with locking parts for locking the left and right protective shells 2 when closed. One end of the cavity is open and provided with a plurality of limit strips 3 for connecting the corrugated pipe. The other end of the cavity is open and provided with a plurality of limit bumps for connecting the connector. The number of limit bumps is related to the connected connector and is at least two, which can hold the upper and lower surfaces of a convex edge connected to the connector to prevent the connector from moving back and forth along the axis. As Figure 1 shown, in this specific embodiment, it is exemplified that there are 3 limit strips 3, which are respectively defined as the first limit strip 31, the second limit strip 32, and the third limit strip 33 from top to bottom for the convenience of description. The limit strip 3 is used to be stuck and connected with the corrugated pipe. There are 3 limit bumps, which are respectively the first limit bump 41, the second limit bump 42, and the third limit bump 43 from top to bottom. The left protective shell 1 and the right protective shell 2 are provided with through glue injection holes 10, and the axis of the glue injection hole 10 is not parallel to the axis of the first cavity 9.

[0024] It further includes a glue injection hole plug 11. The glue injection hole plug 11 includes an end portion and a plug portion. The outer diameter of the plug portion is in interference fit with the inner diameter of the glue injection hole 10. The plug portion can be a threaded structure, which is more convenient to rotate and screw into the glue injection hole 10 while ensuring interference fit and sealing. The glue injection hole plug 11 is one of the sealing means for plugging the glue injection hole 10. The installation and cooperation of the glue injection hole plug 11 with the left housing 1 and the right housing 2 are as follows Figure 2 shown. When injecting glue, one end of the housing of the present utility model connected to the connector can be inclined downward or perpendicular downward. When injecting glue, the glue flows downward, that is, toward the connector direction, and flows to the connector to complete the sealing between the wires and between the wires and the tail of the connector. Due to the fluidity of the glue, the glue injection through the glue injection hole on one side is relatively slow. It can be coordinated with the glue injection holes respectively provided on the upper surfaces of the left and right housings, and the glue is injected from both sides in cooperation.

[0025] Positioning plates 5 are respectively provided on one side of the opening and closing of the left housing 1 and the right housing 2. Corresponding fixing holes 6 are provided on the positioning plates 5. Fixing members pass through the fixing holes 6 to connect the positioning plates 5 with the corresponding structures of the vehicle and the engine. After installation, the fixing holes 6 on the left housing 1 and the right housing 2 coincide. The fixing members (not shown in the drawings) can be cable ties or screws. The cable ties pass through the fixing holes 6 and are fixed to the corresponding positions of the vehicle and the engine, or the screws pass through the fixing holes 6 and are fixed to the corresponding positions of the vehicle and the engine. Through the designed positioning plates 5, fixing holes 6 and fixing members, it is convenient to fix at the corresponding position of the vehicle engine and determine the position of the connector.

[0026] The connecting member is a connecting piece 12. The connecting piece 12 is V-shaped. The connecting piece 12 is made of a flexible material, such as rubber or plastic. The connecting piece 12 can deform as the left housing 1 and the right housing 2 rotate relative to each other, or in other words, in different opening or closing states. When the left housing 1 and the right housing 2 are opened, the connecting piece 12 expands into a V shape. When the left housing 1 and the right housing 2 are closed, the two inner surfaces of the V shape of the connecting piece 12 are in contact with each other.

[0027] Between the lowermost limiting strip 3 that closely cooperates with the wave crest of the corrugated pipe and the uppermost limiting convex block 4 that closely cooperates with the connector is a first cavity 9, which defines the maximum space for injecting glue. Correspondingly, in this specific embodiment, the lowermost limiting strip 3 that closely cooperates with the wave crest of the corrugated pipe, the limiting strip 3 is the third limiting strip 33, and the uppermost limiting convex block 4 that closely cooperates with the connector, the limiting convex block 4 is the first limiting convex block 41. Due to the close cooperation between the corrugated pipe and the limiting strip 3 with corresponding inner diameter dimensions, and the close cooperation between the connector and the corresponding limiting convex block 4, the sealing performance of the two ends of the closed housing during glue injection is ensured, and the glue will not continue to flow toward the corrugated pipe or the connector. At least one side of the connecting piece 12 is provided with a baffle 13, as Figure 3As shown in the figure, the length of the baffle 13 in the radial direction of the protective shell is the height between the lowermost limiting strip 3 and the uppermost limiting bump 4. That is, when the left protective shell 1 and the right protective shell 2 are closed, the upper surface of the baffle 13 abuts against the lowermost limiting strip 3 (the third limiting strip 33), and the lower surface abuts against the uppermost limiting bump 4 (the first limiting bump 41), so as to prevent glue from flowing into the inner surfaces where the connecting pieces 12 abut against each other when the left protective shell 1 and the right protective shell 2 are closed and glue is injected.

[0028] The locking parts are the mutually cooperating buckle 7 and the latch 8, which are respectively arranged on the left protective shell 1 and the right protective shell 2. Preferably, two sets of locking parts are provided. Near the upper and lower openings of the protective shell, the clamping and fixing are firm. One set of locking parts refers to a buckle 7 and a matching latch 8.

[0029] The area where the limiting strip 3 and the limiting bump 4 are located is the connecting part. A clamping ring 14 is horizontally arranged on one of the protective shells corresponding to the position of the connecting part. The clamping ring 14 is a non-closed ring, and the clamping ring 14 is used to clamp the outer diameter of the corrugated pipe or the connector, and cooperate with the limiting strip 3 or the limiting bump 4 to increase the connection stability between the corrugated pipe or the connector and the protective shell. A clamping ring groove 15 is arranged at the corresponding position on the other protective shell. When the left protective shell 1 and the right protective shell 2 are closed, the clamping ring groove is used to accommodate the clamping ring 14. At least two sets of clamping rings 14 are provided. One set of clamping rings 14 is arranged in the upper connecting part, that is, the connecting part area where the limiting strip 3 is located. One set of clamping rings 14 is on the left and right side walls of the left protective shell 1. The second set of clamping rings 14 is arranged in the lower part of the connecting part, that is, the area where the connecting bump is located, and is used to connect the connector.

[0030] The glue injection holes 10 on the left protective shell 1 and the right protective shell 2 are in corresponding positions. When the two are closed, the axes of the glue injection holes 10 are on the same straight line. Two glue injection holes 10 are designed, which are respectively located on the left protective shell 1 and the right protective shell 2. One reason is that when using one glue injection hole 10 for injecting glue, the other glue injection hole 10 is convenient for exhausting air. Another reason is that if there is only one glue injection hole 10, it cannot ensure that the injection is full. Filling full means the sealing between the wires and between the wires and the tail of the connector. When this situation occurs, it is also necessary to inject glue from both sides respectively. Two glue injection holes 10 can ensure the glue injection effect.

[0031] Working process:

[0032] A wire harness connector fixing housing with glue injection holes. When the housing, bellows, and connector are installed and adapted, and the left housing 1 and the right housing 2 are closed, the buckle 7 and the buckle 7 are locked, and the baffle 13 naturally extends into the inner wall of the left housing 1 or the right housing 2 to prevent glue from flowing into the connection pieces 12 during glue injection. Glue is injected into the housing through the glue injection holes 10, and the two glue injection holes 10 are injected with glue respectively. When the injection is full, the sealing between the wires and between the wire and the tail of the connector is completed. The cost is relatively low, but the actual effect is good, which avoids moisture from entering the mating part of the connector through the gap between the multi-strand wire and the tail of the connector; the design of the baffle 13 on the connection piece 12, as well as the design of the limiting strip 3 and the limiting convex block 4, cooperate to limit the glue injection area and prevent glue leakage. The added positioning plate 5, fixing holes 6, and fixing parts are used for installation in the vehicle to facilitate positioning. The cooperation of the snap ring 14 and the snap ring groove 15 can further limit the position of the bellows, and the locking part is used to lock when the housing is closed. Specific Embodiment 2

[0033] The difference between this specific embodiment and Specific Embodiment 1 is that the limiting strip 3 is used to be stuck and connected to the bellows. For bellows of different sizes, the inner diameters of the adapted limiting strips 3 are different, so limiting strips 3 with different inner diameter sizes are applicable. In this specific embodiment, the inner diameter sizes of the limiting strip 3 gradually decrease from the first limiting strip 31 to the third limiting strip 33.

[0034] The inner diameter sizes of the plurality of limiting strips 3 are smaller closer to the glue injection hole 10. This design is for the limiting strip 3 to be suitable for connecting bellows of different sizes. Within the adaptable range, as the sizes of the wave crests and wave troughs of the bellows become smaller, the limiting strip 3 for connection and cooperation gets closer to the glue injection hole 10.

[0035] Between the lowermost limiting strip 3 that closely cooperates with the wave crest of the corrugated pipe and the uppermost limiting projection 4 that closely cooperates with the connector is a first cavity 9, which defines the maximum space for injecting glue. Corresponding to this specific embodiment, if the limiting strip 3 adapted to the corrugated pipe is the third limiting strip 33 and the limiting projection 4 that closely cooperates with the connector is the first limiting projection 41, then the corresponding first cavity 9 is the cavity between the lower surface of the first limiting strip 31 and the upper surface of the first limiting projection 41; if the limiting strip that closely cooperates with the corrugated pipe is the second limiting strip 32 and the limiting projection 4 that closely cooperates with the connector is the second limiting projection 42, then the first cavity 9 is the cavity between the lower surface of the second limiting strip 32 and the upper surface of the second limiting projection 42. That is, the range of the first cavity 9 is not fixed and is the cavity formed by the corrugated pipe and the limiting strip 3, the connector and the limiting projection 4, and the inner walls of the left housing 1 and the right housing 2. Since the corrugated pipe closely cooperates with the limiting strip 3 of the corresponding inner diameter size and the connector closely cooperates with the corresponding limiting projection 4, the sealing performance of the two ends of the closed housing during glue injection is ensured, and the glue will not continue to flow to the corrugated pipe or the connector. At least one side of the connecting piece 12 is provided with a baffle 13, and the length of the baffle 13 in the radial direction of the housing is the height between the lowermost limiting strip 3 and the uppermost limiting projection 4. That is, when the left housing 1 and the right housing 2 are closed, the upper surface of the baffle 13 abuts against the lowermost limiting strip 3, and the lower surface abuts against the uppermost limiting projection 4, so as to prevent the glue from flowing into the inner surface where the connecting pieces 12 abut against each other when the left housing 1 and the right housing 2 are closed and glue is injected. The baffle 13 can be provided with a notch to adapt to the second limiting strip 32, the second limiting projection, etc. Specific Embodiment 3

[0036] The difference between this specific embodiment and Specific Embodiment 1 is that, as Figure 4 shown, the positioning plate 5 includes a first positioning plate 16 and a second positioning plate 17. The axes of the first positioning plate 16 and the second positioning plate 17 are non-parallel or non-coincident, and there is an included angle between them. The left side of the first positioning plate 16 is connected to the left housing 1 or the right housing 2, and the second positioning plate 17 can be connected to the corresponding parts of the vehicle and the engine through fixing parts. The fixing holes 6 include a first fixing hole 18 and a second fixing hole 19. The first fixing hole 18 is on the first positioning plate 16, and the second fixing hole 19 is on the second positioning plate 17. This design is for multi-directional fixing, and the fixing positions are designed as described above, one longitudinal hole and one transverse hole, which is convenient for determining the position.
