[0002] In the fields of oil exploration, geological survey and similar industries, logging technology is an important means to obtain underground geological information. The precision and adaptability of its equipment are crucial for data accuracy and operation efficiency. With the continuous progress of logging technology, logging instruments are increasingly developing towards miniaturization and integration, and at the same time, more complex and diverse requirements are put forward for the design of supporting connectors. The design of traditional connector sockets often follows the symmetry principle, that is, the same pin arrangement is adopted at both ends of the socket. For example, both ends are arranged in a circumferential uniform distribution of 7 cores. Although this design is convenient for standardized production and installation, it has limitations when facing space limitations, equipment compatibility requirements or special detection requirements under specific working conditions. For example, in some logging operations, due to the extremely compact internal space of the instrument, the traditional symmetric arrangement cannot be adapted, resulting in ineffective installation. In addition, with the increasing personalized needs of customers for logging equipment, higher requirements are also put forward for the customization service of connector sockets.

[0006] Further, a first cover plate is detachably arranged at the inner bottom of the groove. A first first-order stepped hole corresponding to each jack is formed in the first cover plate, and the large-diameter hole of the first first-order stepped hole is close to the inner bottom of the groove. The jack is a second-order stepped hole, and the second-order stepped hole sequentially includes a first large-diameter hole, a small-diameter hole, and a second large-diameter hole from a position far from the groove to a position close to the groove. One end of the conductor cylinder abuts against one end of the second large-diameter hole close to the small-diameter hole, and the other end of the conductor cylinder abuts against the large-diameter hole of the first first-order stepped hole.

A second first-order stepped hole corresponding to each pin hole is formed in the second cover plate, and the large-diameter hole of the second first-order stepped hole is close to the end face of the covered bowl. The pin hole is a third first-order stepped hole, and the large-diameter hole of the third first-order stepped hole is close to the second cover plate. A boss is arranged on a part of the pin extending into the pin hole, and the boss abuts between the large-diameter hole of the second first-order stepped hole and the large-diameter hole of the third first-order stepped hole.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] An electrical connector socket for a petroleum logging instrument provided by the utility model is different from sockets with the same pin arrangement at both ends. The pins are flexibly arranged in an area on one side of the upper end surface of the bowl-shaped cover. Wires are arranged in the groove, and the wires are used to achieve one-to-one corresponding electrical connection between the pins and the conductor cylinders in the jacks.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0025] Combined with Figures 1 to 4 As shown, the embodiment of the present utility model provides an electrical connector socket for a petroleum logging instrument, including a columnar base 1. A groove 2 is formed on one end face of the columnar base 1, and a plurality of jacks penetrating the groove 2 are formed on the other end face of the columnar base 1. A conductor tube 3 is arranged in each jack. The groove 2 is detachably covered with a cover bowl 4. Pin holes equal in number to the jacks are formed in a side area on the upper end face of the cover bowl 4. A pin 5 is arranged in each pin hole. The part of each pin 5 extending out of the cover bowl 4 is horizontally bent in the same direction. Each pin 5 is correspondingly connected to a conductor tube 3 through a wire 6.

[0026] Specifically, the columnar base 1 is made of an insulating material. The overall shape of the columnar base 1 is cylindrical. A circular groove 2 is formed in the central area of one end face of the columnar base 1, and the depth of the groove 2 is designed according to actual needs. On the other end face of the columnar base 1, a plurality of jacks are formed according to design requirements. These jacks are circumferentially distributed around the axis of the columnar base 1. A conductor tube 3 is fixedly installed in each jack. The conductor tube 3 is made of a material with good electrical conductivity (such as copper or gold-plated copper alloy) and is used to transmit electrical signals.

[0027] Similarly, the covered bowl 4 is made of an insulating material that matches the columnar base 1, and its shape is adapted to the groove 2 to ensure that it can be tightly covered on the groove 2. On the upper end surface of the covered bowl 4, pin holes equal in number to the jacks are provided in a one-side area (non-central symmetric position). The size and shape of these pin holes are designed according to the specific specifications of the pins 5 to ensure that the pins 5 can be firmly inserted and maintain good electrical contact. A pin 5 is arranged in each pin hole. The pin 5 is made of a material with good electrical conductivity. One end of it extends into the pin hole and is connected to the wire 6, and the other end extends out of the covered bowl 4 and is horizontally bent in the same direction. This design not only facilitates the connection with external devices or cables but also effectively reduces space occupation and improves the flexibility of connection. To achieve the electrical connection between the pin 5 and the conductor cylinder 3, an insulated wire 6 is used for connection. One end of the wire 6 is fixed to the pin 5 by welding, crimping or other reliable connection methods, and the other end passes through the corresponding channels of the covered bowl 4 and the columnar base 1 and finally realizes electrical connection with the conductor cylinder 3. During the connection process, it is necessary to ensure that the insulating layer of the wire 6 is intact to avoid safety hazards such as short circuits or electric leakage.

[0028] During assembly, the fabricated covered bowl 4 is covered on the groove 2 of the columnar base 1 and fixed by screws, buckles or other fastening devices. Subsequently, electrical performance tests are carried out on the connector socket, including insulation resistance test, contact resistance test, signal transmission performance test, etc., to ensure that it meets the design requirements.

[0029] Through the above specific implementation manners, an electrical connector socket for a petroleum logging instrument provided by the present utility model has an asymmetric pin arrangement method, can flexibly adapt to the space layout and pin arrangement requirements of different logging instruments, and improves the compatibility and personalized service ability of logging equipment. At the same time, the socket also has the advantages of simple structure, convenient installation, stable electrical performance, etc., and can be widely used in petroleum exploration, geological survey and similar industrial fields.

[0030] In an implementable manner, as Figure 1 shown, a first cover plate 7 is detachably arranged at the inner bottom of the groove 2. The first cover plate 7 is provided with first first-order stepped holes corresponding to the jacks one by one, and the large-diameter holes of the first first-order stepped holes are close to the inner bottom of the groove 2. The jacks are second-order stepped holes, and the second-order stepped holes are, from the position far from the groove 2 to the position close to the groove 2, a first large-diameter hole, a small-diameter hole and a second large-diameter hole in sequence. One end of the conductor cylinder 3 abuts against one end of the second large-diameter hole close to the small-diameter hole, and the other end of the conductor cylinder 3 abuts against the large-diameter hole of the first first-order stepped hole. The wire 6 passes through the small-diameter hole of the first first-order stepped hole and then is connected to the corresponding conductor cylinder 3.

[0031] Specifically, the first cover plate 7 is made of an insulating material that matches the columnar base 1 and the cover bowl 4. Its shape and size match the inner bottom of the groove 2 to ensure a tight fit and stable installation. On the first cover plate 7, corresponding first-order stepped holes are provided according to the number and positions of the jacks. The design of the first-order stepped holes is to cooperate with the jacks (i.e., the second-order stepped holes) to form a stable support and positioning structure. Specifically, the large-diameter hole part of the first-order stepped hole is close to the inner bottom of the groove 2 for docking with the second large-diameter hole of the jack, while the small-diameter hole part is used to pass through the wire 6 and connect with the conductor cylinder 3.

[0032] As one of the key components of the connector, the jack is designed as a second-order stepped hole, which is successively the first large-diameter hole, the small-diameter hole, and the second large-diameter hole from the position far from the groove 2 to the position close to the groove 2. This design facilitates the installation and positioning of the conductor cylinder 3. One end of the conductor cylinder 3 abuts against one end of the second large-diameter hole close to the small-diameter hole to form a stable mechanical support, and the other end is connected to it after the wire 6 passes through the small-diameter hole of the first-order stepped hole, realizing the transmission of electrical signals. During the connection process, it is necessary to ensure that the connection between the wire 6 and the conductor cylinder 3 is firm and reliable to avoid electrical failures caused by loosening or falling off.

[0033] Preferably, the small-diameter hole of each jack is a tapered hole, and the small end of the tapered hole faces the second large-diameter hole. The tapered hole has a guiding function, improving the accuracy and smoothness when the plug is inserted into the jack. That is to say, the small-diameter hole of each jack is designed as a tapered hole, where the small end of the tapered hole faces the second large-diameter hole. This design enables the jack to gradually guide the plug into the correct position when the plug approaches, ensuring that the plug can be inserted smoothly and steadily, while reducing the risk of damage or electrical failures caused by improper insertion. This guiding function not only improves the insertion efficiency of the plug but also reduces the requirement for operation accuracy, enabling reliable electrical connection even in relatively harsh working environments.

[0034] It can be seen that the design of the tapered hole enhances the guiding function of the jack, improves the alignment accuracy between the plug and the jack, and reduces the risk of poor electrical contact or short circuit caused by misalignment.

[0035] In an implementable manner, as Figure 1 shown, a second cover plate 8 is detachably connected to the end face of the cover bowl 4 facing the groove 2. Second-order stepped holes corresponding to the pin holes are provided on the second cover plate 8, and the large-diameter holes of the second-order stepped holes are close to the end face of the cover bowl 4. The pin holes are third-order stepped holes, and the large-diameter holes of the third-order stepped holes are close to the second cover plate 8. A boss is provided on the part of the pin 5 extending into the pin hole, and the boss abuts between the large-diameter holes of the second-order stepped hole and the third-order stepped hole.

[0036] Specifically, the second cover plate 8 is designed to be detachably connected to one end face of the covered bowl 4 facing the groove 2, making the replacement and maintenance of the second cover plate 8 convenient and fast. At the same time, it also improves the modularity and maintainability of the entire connector. The second cover plate 8 is made of a material matching that of the covered bowl 4. On the second cover plate 8, corresponding second first-order stepped holes are provided according to the number and positions of the pin holes. The large-diameter hole part of the second first-order stepped hole is close to the end face of the covered bowl 4 for docking with the large-diameter hole part of the pin hole (i.e., the third first-order stepped hole). This design not only facilitates the insertion and positioning of the pin 5 but also provides sufficient supporting area to ensure a stable connection between the pin 5 and the connector. The pin hole is designed as a third first-order stepped hole, and its large-diameter hole part is close to the second cover plate 8. A boss is provided on the part of the pin 5 extending into the pin hole. This design is to form contact and support between the large-diameter hole of the second first-order stepped hole and the large-diameter hole of the third first-order stepped hole. The design of the second cover plate 8 and the second first-order stepped holes thereon makes the connection between the pin 5 and the connector more stable and reliable, avoiding electrical failures caused by the loosening or misalignment of the pin 5.

[0037] Preferably, as shown in combination with Figures 1 to 4 the second cover plate 8 and the covered bowl 4 are connected by a first bolt 9; the covered bowl 4, the first cover plate 7, and the columnar base 1 are connected by a second bolt 10. That is to say, the connection between the second cover plate 8 and the covered bowl 4 by the first bolt 9 can ensure the stable installation of the second cover plate 8 on the covered bowl 4. The covered bowl 4, the first cover plate 7, and the columnar base 1 are connected by the second bolt 10. By using bolt connection, close contact and support can be formed between the components, ensuring that the connector socket will not become loose or fall off during use. Bolt connection has the property of being detachable, making it convenient and fast to operate when components need to be replaced or repaired.

[0038] In one implementable manner, each pin hole is waist-shaped, and the part of the pin 5 extending into the pin hole is waist-shaped. By adopting the waist-shaped structure, the rotation of the pin 5 after insertion is prevented, thereby improving the connection stability and reliability. More specifically, each pin hole is designed to be waist-shaped, that is, its cross-sectional shape is similar to an elongated rectangle or oval. This design enables the pin hole to maintain a certain width while increasing the dimension in the length direction, providing more stable support and positioning for the pin 5. Corresponding to the waist-shaped pin hole, the part of the pin 5 extending into the pin hole is also designed to be waist-shaped. This design makes the cross-sectional shape of the pin 5 closely match that of the pin hole after the pin 5 is inserted into the pin hole, forming a structure similar to a "lock". This structure not only enhances the contact area and friction between the pin 5 and the pin hole, but also effectively prevents the rotation of the pin 5 when subjected to external forces. When the pin 5 is inserted into the waist-shaped pin hole, its waist-shaped part fits with the shape of the pin hole, forming a stable mating relationship. Due to the special nature of the waist-shaped structure, when the pin 5 is subjected to torque in the axial direction, it will be resisted by the side wall of the pin hole, thereby restricting its rotational freedom. This design reduces the risk of poor electrical contact or short circuit caused by pin rotation. At the same time, the design of the waist-shaped structure also simplifies the assembly process and improves production efficiency.

[0039] In one implementable manner, in combination with Figure 3 As shown, a number of pin holes are arranged in two rows, and the height of the pin 5 extending out of the cover bowl 4 in one row of pin holes is lower than the height of the pin 5 extending out of the cover bowl 4 in the other row of pin holes. By adopting the method of height dislocation, the interference problem between pins in different rows is effectively avoided, and the connection reliability and stability are improved.

[0040] Specifically, the connector socket arranges a number of pin holes in two rows. This layout method not only saves space and makes the connector socket more compact. To avoid the interference problem between pins in different rows, a design of pin height dislocation is adopted, that is, the height of the pin 5 extending out of the cover bowl 4 in one row of pin holes is lower than that of the pin 5 in the other row of pin holes. This height difference makes the pins in the two rows form a staggered layout in space, thus avoiding the possible mutual collision phenomenon during the connection process.

[0041] Preferably, in combination with Figure 4 As shown, a number of jacks are annularly and evenly arranged in an array around the central axis of the columnar base 1. The annular uniform array means that a number of jacks are arranged around the central axis of the columnar base 1 at equal intervals. This arrangement makes each jack located on the same circumference and keeps a uniform spacing between each other. The annular layout makes the jacks form a stable support structure inside the socket. At the same time, the annular layout enables the socket to adapt to the plug insertion requirements in different directions.

[0042] Preferably, in combination with Figure 1 As shown, an annular groove 11 is formed on the outer cylindrical surface of the columnar base 1, and the annular groove 11 is used to accommodate the sealing ring. The annular groove 11 is formed on the outer cylindrical surface of the columnar base 1. When the connector socket is connected to other devices, the sealing ring is compressed and closely adheres to the connection interface, forming a reliable sealing barrier to effectively prevent external liquids, dust and other impurities from entering the connector, providing a reliable guarantee for the electrical connection in the harsh environment of oil well logging.

[0043] In an embodiment, in combination with Figure 3 As shown, a guide post 12 is provided on the end face of the covered bowl 4 away from the groove 2. The guide post 12 is located on the side of the outermost two pins 5 and is used for guiding and positioning with the device to be mated. Specifically, the guide post 12 is located on the side of the outermost two pins 5. Such a layout will neither interfere with the normal functions of the pins 5 nor effectively provide a guiding effect for the docking between the connector socket and the device to be mated. When the connector socket approaches the device to be mated, the guide post 12 will first contact the corresponding structure on the device, guiding the socket to move in a predetermined direction and path until it reaches the correct docking position, ensuring that the connector socket can accurately find the correct position during the docking process, thereby improving the reliability and stability of the connection, enhancing the accuracy and efficiency of the connection, reducing the risk of docking errors caused by improper manual operation, and reducing the failure rate and maintenance cost of the device.
