Description

Technical Field

[0001] This utility model belongs to the field of compressor connector technology, specifically relating to a connector for a sealed terminal block of a refrigerator compressor. Background Technology

[0002] The main problem encountered by traditional compressor connectors when assembling wire harnesses is the insufficient stability of the terminals. Specifically, during or after assembly, the terminals may fall off the wire harness, leading to electrical connection failure. This may be due to reasons such as loose riveting, poor material compatibility, or excessive mechanical stress. Secondly, the metal terminal structure is not well adapted to the stepped design of the connector, making it easy for the terminals to come off the plastic housing connector due to external forces during use. Utility Model Content

[0003] The present invention aims to provide a connector for the sealed terminal of a refrigerator compressor, thereby solving some technical problems existing in the existing compressor connectors.

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

[0005] A connector for a sealed terminal block of a refrigerator compressor includes a connector housing and a locking plate. The connector housing has a terminal socket, and the locking plate includes a locking tongue and a connecting arm. The locking tongue is inserted into the terminal socket. Two wedge-shaped protrusions are also provided on the surface of the connector housing. The connecting arm is located above the locking tongue and is integrally formed with the locking tongue. A limiting hole is provided on the connecting arm. When the locking tongue is inserted into the terminal socket, the connecting arm moves on the upper surface of the connector housing, and the wedge-shaped protrusions slide into the limiting hole of the connecting arm.

[0006] Furthermore, the length of the locking tongue is set to be able to press against the head of the metal terminal inside the terminal socket.

[0007] Furthermore, the number of terminal sockets, locking tongues, and connecting arms corresponds accordingly.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: The connector shell surface of this utility model is provided with two wedge-shaped protrusions, which can slide into the limiting hole on the connecting arm during the assembly of the locking piece; this fit can prevent the locking piece from coming out, thereby resisting the pulling force of the metal terminal in the direction of the wire; after assembly, the locking tongue can press against the head of the metal terminal inside the terminal socket, preventing it from moving backward, reducing the activity space of the metal terminal in the connector shell, and reducing the risk of damage caused by relative movement.

[0009] This invention effectively solves the problem of terminal detachment / loss of wires in traditional connectors, providing a more reliable electrical connection solution for refrigerator compressors. By ensuring that the metal terminals are firmly fixed inside the connector, it not only improves the performance of the product but also extends its service life. In addition, because the number of terminal sockets, locking tongues and connecting arms are matched, it ensures that each terminal can be locked and protected accordingly, making the entire connection system more coordinated and consistent. Attached Figure Description

[0010] The accompanying drawings are provided to further illustrate the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation thereof. In the drawings:

[0014] Figure 4 for Figure 3 The left view. Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The present invention will be further described in detail below with reference to the embodiments.

[0017] like Figure 1-4 As shown, a specific embodiment 1 of the connector for the sealed terminal block of a refrigerator compressor provided by this utility model is as follows:

[0018] A connector for a sealed terminal block of a refrigerator compressor includes a connector housing 1 and a locking plate 2. The connector housing 1 has a terminal socket 3. The locking plate 2 includes a locking tongue 4 and a connecting arm 5. The locking tongue 4 is inserted into the terminal socket 3. Two wedge-shaped protrusions 6 are also provided on the surface of the connector housing 1. The connecting arm 5 is located above the locking tongue 4 and is integrally formed with the locking tongue 4. A limiting hole 7 is provided on the connecting arm 5. When the locking tongue 4 is inserted into the terminal socket 3, the connecting arm 5 moves on the upper surface of the connector housing 1, and the wedge-shaped protrusions 6 slide into the limiting hole 7 of the connecting arm 5.

[0019] To prevent the metal terminals riveted to the wires from falling out of the connector housing 1, this embodiment uses a locking plate 2 to assemble with the connector housing 1. The wedge-shaped protrusion 6 engages with the limiting hole 7. After assembly, the limiting hole 7 prevents the wedge-shaped protrusion 6 from dislodging, resisting the pulling force in the direction of the metal terminal wire. This completely avoids terminal deformation and damage to the connector housing 1 that could lead to terminal detachment. After assembly, the locking tongue 4 can hold the head of the metal terminal inside the terminal socket 3, preventing the terminal from retracting. This significantly reduces the movement space of the metal terminal inside the connector housing 1, lowering the risk of damage due to relative movement between the metal terminal and the connector housing 1. The number of terminal sockets 3, locking tongues 4, and connecting arms 5 corresponds to the number of terminals.

[0020] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
