Problems solved by technology

However, the size of the portion of the locking piece that can be locked to the locking protrusion can only ensure the plate thickness of the locking piece, so the locking protrusion is located at a position that is offset from the plate in the direction of terminal arrangement relative to the locking piece. The location of the thick dimension, so that the locking of the connectors to each other cannot be achieved
In addition, since the above-mentioned engaging piece is made as a part of the socket-side locking metal fitting, its thickness is the same as that of other parts, so there is a limit to the above-mentioned plate thickness dimension.

no. 1 approach

[0048] figure 1 It is a perspective view of the receptacle connector 1 according to this embodiment and the plug connector 2 fitted thereto from above, and shows a state before the connectors are fitted. figure 2 is to make figure 1 It is a perspective view showing the receptacle connector 1 and the plug connector 2 upside down, and is a perspective view showing the plug connector 2 fitted from below.

[0049] The receptacle connector 1 in this embodiment and the plug connector 2 as a mating connector of the receptacle connector 1 are circuit board connectors arranged on the mounting surfaces of different circuit boards (not shown), respectively. and constituted in a direction at right angles to the surface of each circuit board ( figure 1 The up and down direction in the figure) is the connector assembly in the plugging and unplugging direction.

[0050] Such as figure 1 As shown, the receptacle connector 1 has: a receptacle-side housing 10, which is approximately in the...

no. 2 approach

[0105] In the first embodiment, although the lock release operation portion 31B is bent at an acute angle with respect to the connector width direction, in the second embodiment, the lock release operation portion is bent at a right angle toward the outside in the connector width direction. One point is different from the structure of the first embodiment. Figure 9 It is a transverse cross-sectional view of a part of the receptacle connector according to the second embodiment, showing a cross-section perpendicular to the direction in which the connector is inserted and removed. The shape of the receptacle connector of the second embodiment is the same as that of the first embodiment except for the base of the above-mentioned locking metal piece, therefore, for the same parts, "300" is added to the reference numerals of the first embodiment and omit its description.

[0106] Such as Figure 9 As shown, for the locking metal fitting 330 in the second embodiment, the two strip...

no. 3 approach

[0109] In the first embodiment, although at least a part of the locking portion 33 and the erected portion 32 are located in the inner groove portion 18B of the protruding wall 12, in the third embodiment, the locking portion and the erected portion of the locking metal piece are located in the terminal It differs from the structure of the first embodiment in that it is exposed in the arrangement direction and at a position different from the protruding wall of the socket-side housing, and is provided in the storage portion. Figure 10 It is a perspective view showing a receptacle connector 401 according to the third embodiment. The shape of the receptacle connector 401 of the third embodiment is the same as that of the receptacle connector 1 of the first embodiment except for the above-mentioned protruding wall of the receptacle-side housing. Add "400" to the base of the mark and omit its description.

[0110] Such as Figure 10 As shown, the protruding wall 412 of the rece...

Abstract

PROBLEM TO BE SOLVED: To provide an electric connector for a circuit board capable of ensuring a stable locked state of lock parts by enlarging a protruding amount of the lock parts of lock fittings provided in the electric connector for the circuit board, and an electric connector assembly.SOLUTION: A lock fitting 30 includes: a base part which includes a portion extending in a terminal array direction at a lower position of a housing 10; a rising part which rises upwards from a portion of the base part within a range between end walls 15 in the terminal array direction; and a lock part 33 which protrudes from an upper portion of the rising part closer to the end wall 15 and can be locked upwards to a locked part which is provided in an opposite connector 2. The base part of the lock fitting 30 includes an elastic deformation portion 31C-1 which is elastically deformed in the terminal array direction so as to allow the rising part and the lock part 33 to move in the terminal array direction away from the end wall 15 corresponding to the lock fitting 30, when external force in the terminal array direction is applied in a connector fitting process.

Description

technical field [0001] The present invention relates to an electrical connector for a circuit board and an electrical connector assembly including the electrical connector for a circuit board and a mating connector, wherein the electrical connector for a circuit board is arranged on a mounting surface of a circuit board, and the mating connector The up-and-down direction at right angles to the mounting surface is regarded as the connector insertion and extraction direction, and is fitted and connected to the circuit board from above with the electrical connector. Background technique [0002] Such an electrical connector assembly is disclosed in Patent Document 1, for example. In this Patent Document 1, the receptacle-side housing of the receptacle connector has a rectangular planar shape, and the receptacle-side terminals are aligned and held with the longitudinal direction thereof being the terminal arrangement direction. The receptacle-side housing has a bottom wall faci...
