Description

Technical Field

[0001] This utility model relates to automotive electrical signal connectors, and more particularly to a bend-through cylinder connector. Background Technology

[0002] Cylinder-through connectors are the connection medium used in automotive transmissions to achieve electrical connections between the inside and outside of the cylinders. They are commonly used in automotive transmissions or engines to transmit electrical signals between the cylinders. In practical applications, due to the limited space and environment of the transmission or engine, it is difficult to insert matching external connectors. Therefore, in the specific application environment inside a car, the original structural design no longer meets the application requirements of easy insertion and operation of cylinder-through connectors. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a bend-type cylinder connector that is suitable for narrow installation spaces and facilitates plug-in operation, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A bendable cylinder connector includes a connector housing that is bent at 90°. A curing colloid is disposed within the connector housing, and multiple L-shaped pins are inserted through the curing colloid. The two ends of each pin extend to the inner sides of the openings at both ends of the connector housing. The connector housing includes a flange portion with two symmetrically arranged connector bushings. The connector housing also includes an outer connecting portion and an inner connecting portion, with the flange portion located outside the inner connecting portion.

[0006] Preferably, the cured adhesive contains two rows of PIN pins.

[0007] Preferably, the connector bushing is an "I"-shaped bushing with an outer annular groove.

[0008] Preferably, the connector housing is a plastic housing.

[0009] Preferably, two sealing ring grooves are formed on the outer side of the inner connecting part, and a sealing ring is provided in the sealing ring groove.

[0010] In the elbow-type cylinder connector disclosed in this utility model, the connector housing serves as the main housing structure, which is used to fix the cylinder and provide space for multiple pins. The two symmetrical connector bushings on the flange are used to achieve a fixed connection. For the internal structure of the connector housing, the multiple pins are fixed by the cured adhesive. The two ends of the pins extend to the inner sides of the openings at both ends of the connector housing to facilitate mating. Since the connector housing is bent at 90° and the multiple pins are bent in an "L" shape, the cylinder connector of this utility model is not only suitable for narrow installation spaces, but also convenient for assembly personnel to insert and operate, thus better meeting the application requirements.

[0016] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0017] This utility model discloses a bend-type cylinder connector, combined with... Figures 1 to 5 As shown, it includes a connector housing 1, which is bent at 90°. A curing colloid 2 is provided inside the connector housing 1. A plurality of L-shaped PIN pins 3 are inserted through the curing colloid 2. The two ends of the PIN pins 3 extend to the inner sides of the openings at both ends of the connector housing 1. The connector housing 1 includes a flange 4, on which two symmetrically arranged connector bushings 5 ​​are provided. The connector housing 1 includes an outer connecting part 10 and an inner connecting part 11. The flange 4 is located on the outer side of the inner connecting part 11.

[0018] In the above structure, the connector housing 1 serves as the main housing structure, which is used to fix the cylinder and provide space for multiple PIN pins 3. The two symmetrical connector bushings 5 ​​provided on the flange 4 are used to achieve the purpose of fixed connection. For the internal structure of the connector housing 1, the multiple PIN pins 3 are fixed by the curing adhesive 2. The two ends of the PIN pins 3 extend to the inner side of the openings at both ends of the connector housing 1 to facilitate insertion and matching. Since the connector housing 1 is bent at 90° and the multiple PIN pins 3 are bent in an "L" shape, the cylinder connector of this utility model is not only suitable for narrow installation spaces, but also convenient for assembly personnel to insert and operate, thus better meeting the application requirements.

[0019] As a preferred embodiment, the cured colloid 2 is provided with two rows of PIN pins 3.

[0020] To facilitate screw fixing, in this embodiment, the connector bushing 5 is an "I"-shaped bushing with an outer annular groove 50.

[0021] Furthermore, the connector housing 1 is a plastic housing.

[0022] In this embodiment, the two ends of the elbow cylinder connector form a 90° angle with the axial direction of the fitting frame opening, thus forming the elbow cylinder connector structure. In the actual production process: when the cylinder connector housing is injection molded, the PIN pins and bushings should be fixed on the fixture in advance before injection molding, so that the PIN pins, bushings and plastic shell are fixed as a whole. Then, the injection molded product is subjected to a glue curing process to eliminate the gap between the PIN pins and the plastic shell and ensure the airtightness of the product. Finally, the sealing ring is assembled on the cured product, and other testing processes are carried out according to the drawing requirements.

[0023] As a preferred sealing method, in this embodiment, two sealing ring grooves 12 are formed on the outer side of the inner connecting part 11, and a sealing ring 13 is provided in the sealing ring groove 12.

[0024] In this embodiment, the through-cylinder connector serves as an electrical signal relay medium, mating with both the external and internal cylinder connectors to achieve electrical connection between the inside and outside of the cylinder. Because the connection environment of an automotive transmission or engine block is relatively small and limited, a certain amount of space is required when mating the other end of the connector. Therefore, this invention employs a bent through-cylinder connector structure design. This bent through-cylinder connector design structurally changes the usage direction of the mating end, making the height of the mated through-cylinder connector relatively lower, thus facilitating the insertion operation.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
